AB  - Lean management (LM) is a set of procedures and principles used in industrial processes for finding and eliminating useless activities. This paper presents the analysis of business practices in small-scale manufacturing enterprises in Serbia in comparison with defined LM principles. Application of LM standards to reduce waste and optimize production in SMEs in Serbia has not been investigated before, although this practice has been successfully used in neighboring countries. The importance of this approach is related to the benefits of improving business practices in SMEs in Serbia. This study shows that enterprises lack a system ensuring that the customer gets a quality product on time, the optimization of production and resources are limited, and a significant difference exists between job requirements and skills. The recommendations to improve operations include introduction of a monitoring and control system to ensure timely delivery and customer satisfaction, and introduction of various LM tools.

AB  - New product development in small manufacturing enterprises on the territory of Serbia was investigated on a representative sample of micro and small enterprises covering a broad range of businesses. It was found that market pull was the prevalent strategy for new product development, which was characterized by close collaboration with customers from the idea to the final product including the R&D activities. Besides customers, the main sources of ideas were competitors and trade fairs or exhibitions. The marketing activities associated with new product introduction were quite limited. These findings were compared with new product development practices in neighboring countries. Based on our findings we propose two measures to improve new product development in small manufacturing enterprises in Serbia: establish a closer cooperation with external knowledge centers (universities, research institutes, innovation centers) and set up innovation networks with complementary partners by actively using the open innovation concept.

AB  - A novel method combining a traditional immersion precipitation process for making membranes with photopolymerization and crosslinking of functional monomers included in the casting solution was used to prepare asymmetric polyethersulfone membranes with submicron particles incorporating glycidyl methacrylate copolymer. In order to introduce sulfonic groups, the epoxide rings of glycidyl methacrylate were opened using two methods. The first method was functionalization with sodium sulfite, and the second was functionalization with sulfuric acid and then grafting with 2-acrylamido-2-methylpropanesulfonic acid. The obtained membranes were characterized using infrared spectroscopy, conductometric titration and water permeability measurements. Scanning electron microscopy and atomic force microscopy were used to investigate the surface morphology and topology of the membranes. Dynamic adsorption of rhodamine B as a model dye was used to demonstrate the suitability of these novel membranes for membrane adsorption since the adsorption capacity for dye cations was much better for the membranes functionalized with sodium sulfite and the membranes grafted with 2-acrylamido-2-methylpropanesulfonic acid compared to the non-functionalized membranes.

AB  - Polyethersulfone membranes with integrated negatively-charged hydrogel of crosslinked poly (acrylamido-2-methylpropane sulfonic acid) were prepared by a combination of a liquid phase inversion process with photopolymerization and crosslinking of functional monomers included in the casting solution. A designed experiment was conducted to select the optimal composition for preparing membranes with a sufficient degree of swelling and ion exchange capacity. Scanning electron microscopy images revealed an ultrafine hybrid structure with an interconnected network of submicron particles embedded within the microporous polyethersulfone support. An intramembrane diffusion model was used to describe kinetics of heavy metal sorption by these hydrogels and the calculated apparent diffusion coefficients were 2-3 times larger than in commercial ion-exchange resins. Equilibrium sorption of heavy metals was described using a semi-empirical Langmuir model.

AB  - Asymmetric polyethersulfone membranes with submicron particles comprising crosslinked poly(glycidyl methacrylate-co-2-acrylamido-2-methylpropane sulfonic acid) were prepared by a combination of a traditional liquid phase inversion process for making membranes with photopolymerization and crosslinking of functional monomers included in the casting solution. Scanning electron microscope images of the membrane cross-section revealed a hybrid structure with an interconnected network of submicron particles embedded within the porous polyethersulfone support. Permeation of toluidine blue solutions through non-functionalized membranes showed a dramatic effect of 2-acrylamido-2-methylpropane sulfonic acid concentration in the casting solution on the dynamic adsorption performance. The epoxide groups present in glycidyl methacrylate copolymer were transformed into amine functionalities by ring opening under alkaline conditions. Permeation of dilute Cu2+ solutions through functionalized membranes demonstrated that the plate height for some of these membranes was an order of magnitude smaller than for commercial particle-filled membranes used in solid phase extraction.

AB  - Properties of sintered NdFeB magnets strongly depend on granulation and size distribution of constituent particles, which requires an efficient method for their separation into relatively narrow size fractions. We investigated two methods of magnetic particle separation from a mixture with different sizes using simulation by finite element method: magnetophoresis and gravity settling. In the case of magnetophoresis magnetic particles ranging in diameter from 1 to 10 m were deflected from the direction of continuous laminar flow by a perpendicular magnetic field. Larger particles were deflected from the direction of laminar flow more than smaller particles. The applied flow rate and strength and gradient of the applied magnetic field were the key parameters in controlling the deflection. The gravity settling model simulated spherical particles falling in heptane. Particles of various sizes were divided according to the time they needed to reach the bottom. The model used an axially symmetric fluid-flow simulation in a moving coordinate system connected with the particle, coupled with an ordinary differential equation for the force balance of the particle (gravity and drag force). The grain accelerated from standstill and rapidly reached its terminal velocity. This velocity was approximately proportional to the square of the particle radius, which led to clear separation of 5-10 um particles from those with a diameter of 1 um.

AB  - Improved permanent magnets are essential for emergent applications in electronic and electric devices. Different attempts have been made to produce nanoscale anisotropic rare-earth magnetic powder based on Nd-Fe-B material. Recently, high energy surfactant assisted ball milling has been proven to be an effective technique to produce anisotropic hard magnetic Nd-Fe-B nanoparticles. In this paper we are presenting our experimental results on high energy ball milling in planetary mill "Puverisette 7 premium line" from "Fritsch". Except milling material, there are several variables which influence the milling process for the selected mill type. They are: mechanical properties of the milling media material (bowls, balls, etc.), ball-to-powder ratio (BPR), extent of filling of the milling bowl, milling atmosphere, milling speed and duration, and type of solution and surfactant for wet milling. We are going to give influence of all these parameters on obtained NdFeB magnetic materials with nanosized dimensions starting from Nd2Fe14B HDD (Hydrogenated Disproportionated Desorbed) material.

AB  - Nanomembranes, freestanding quasi-2D structures with thickness of the order of tens of nm and smaller and a giant aspect ratio with lateral dimensions of the order of millimeters, even centimeters, represent an important building blocks in micro and nanosystems [1], corresponding to ubiquitous bilipid membranes in living cells [2]. In this contribution we present our results in theory, design and experimental fabrication of metallic and metal-dielectric nanomembranes with plasmonic properties, intended for the use in the field of sensing. We first consider different approaches to functionalization and nanostructuring of nanomembranes [3]. These include introduction of noble metal or transparent conductive oxides fillers directly into the nanomembrane, lamination (multilayering) and patterning by 2D arrays of subwavelength nanoholes. Within this context we describe our results on nanofabrication of 8 nm thick chromium-based composite nanomembranes. Biomimetic structures utilizing nanochannel-based pores are also considered. We further present our results related to the design of chemical and biological sensors based on nanomembranes with plasmonic metamaterial properties [4]. Such sensors function as refractometric devices utilizing evanescent near fields as optical concentrators and adsorption-desorption mechanism, which ensures their ultra-high sensitivity that reaches single molecule detection [5]. We present some results on chemical sensors utilizing nanomembranes exhibiting extraordinary optical transmission, as well as those based on doublefishnet structures. Finally we consider the enhancement of infrared detectors by nanomembranes [6] utilizing the designer plasmon mechanism [7].REFERENCES1. Jiang, C., Markutsya, S., Pikus, Y., and Tsukruk, V.

AB  - Asymmetric polyethersulfone membranes with submicron particles comprising crosslinked glycidyl methacrylate copolymer were prepared by a combination of a traditional immersion precipitation process for making membranes with photopolymerization and crosslinking of functional monomers included in the casting solution. As the concentration of polymerizable monomers increased the original macrovoid structure was replaced by a hybrid morphology with microglobules typical of macroporous methacrylate adsorbers embedded within microporous structure with no significant effects on water permeability. The epoxide groups present in glycidyl methacrylate copolymer were transformed into amine functionalities by ring opening under alkaline conditions. Permeation of Orange G solution at low transmembrane pressures was used to demonstrate suitability of these novel membranes for membrane adsorption.

AB  - Novel polyethersulfone membranes with integrated submicron adsorbent particles were prepared by combining photoirradiation with liquid phase inversion. These particles consist of cross-linked poly(glycidyl methacrylate-co-acrylamido-2-methylpropane sulfonic acid), pGMA-AMPS. After membrane preparation, the epoxide groups were reacted with diethylene triamine to incorporate amine functionalities. Membranes were characterized using FTIR-ATR, SEM and dynamic adsorption of copper from a dilute solution. Effects of monomer concentrations on the properties and separation performance of membrane adsorbers are presented.

PDMS network samples for this research were synthesized with the same composition, which are Sylgard 184 (Dow Corning, USA) silicone elastomer base and silicone elastomer curing agent, volume ratio 10:1. Mechanical testing of PDMS elastic properties and bond strength between membranes and oxidized Si wafers, were investigated applying pressurized bulge testing In this paper experimentally determined dependence of the PDMS membrane deflection on pressure load for different membrane thicknesses and sizes of square cavities in Si wafers are given. Also, the influence of different types of Si wafer structuring by anisotropic wet chemical etching on membrane bonding strength were considered.

AB  - A series of polyethersulfone membranes with integrated cross-linked poly(glycidyl methacrylate-co-2-acrylamido-2-methylpropane sulfonic acid) were synthesized using a combination of the traditional immersion precipitation process for making membranes and photopolymerization. Negative charges were introduced using AMPS as a reactive monomer. Presence of sulfonic groups was confirmed by FTIR-ATR spectra. Changes in membrane morphology as a function of AMPS concentration in the casting solution were investigated by SEM. Membrane charge was evaluated from streaming potential measurements using a specially constructed device. Dynamic adsorption of Rhodamine B was used to demonstrate effects of monomer concentration on the properties and separation performance.

AB  - Data tracking and hacking is especially dangerous in modern defence forces where classified data transmission must envolve cryptographic methods for secure and reliable data coding. The more unpredictable the cipher is, the more reliable is the message. Hardware random number generator or true random number generator (TRNG) is crucial part for every telecommunication system that involves secure and confidential electronic data transfer (official state agencies, e-banking, military data networks…) because it generates random numbers from a physical process which provides statistically random noise signals, which are trully unpredictable contrary to pseudo-random number generators generated by various software algorithms. A typical hardware random noise generators employs transducer to convert random physical process (thermal noise, photoelectric effect or other quantum phenomena) to electrical signal, amplifiers and AD convertors. On the other hand, pseudo-random number generation based on methods and algorithms may be examined by statistical tests for randomnes and proove if it is cryptographically secure. We analyze the possibility to implement adsorption-based sensors noise for the creation of allgorithm for pseudo-random number generaton and also the possibility of adsorption-based hardware random generator.

AB  - Polyethersulfone (PES) is frequently used for high-performance ultrafiltration membranes. Functionalization of PES membranes is required to introduce new groups for specific applications, such as affinity membranes for bioseparations [1]. Functionalization methods include bulk modification of PES material, blending of PES with another material, or surface modification of PES membranes [2]. In this work a novel method for introducing functional groups in asymmetric PES membranes is presented [3]. A cast film comprising PES, glycidyl methacrylate (GMA) and a common solvent was exposed to UV irradiation to form a gel of crosslinked polyGMA. The gel was then immersed in a water bath to create an asymmetric membrane with crosslinked polyGMA particles, as shown in Fig. 1. A simple treatment of these membranes with diethylene triamine was used to open the epoxide rings in polyGMA particles and introduce amine functional groups. The effects of monomer concentrations on the properties and separation performance of these novel membrane adsorbers will be presented.

AB  - Ultrafiltration (UF) membranes are currently used in industry for the concentration of proteins and other macromolecules. Performance of UF membranes is generally limited by a trade-off between permeability and selectivity [1]. However, electrically-charged ultrafiltration membranes can provide a dramatic improvement in ultrafiltration performance [2]. Novel UF membranes were made by combining traditional immersion precipitation process for making membranes with photopolymerization of the casting solution comprising polyethersulfone, glycidyl methacrylate and other reactive monomers. Negative charges were introduced either by initially using 2-acrylamido-2-methylpropane sulfonic acid as a reactive monomer, or were later created by epoxide ring opening of crosslinked glycidyl methacrylate. As shown in Fig. 1, selectivity of these membranes significantly improved as the concentration of negatively-charged groups in the membrane increased. The effects of membrane composition on the properties and separation performance of these novel UF membranes will be presented.

AB  - Hydrogels containing strong acid groups have been used in the past for the removal of heavy metals. Unfortunately such hydrogels exhibit poor mechanical properties and are generally difficult to handle. In this work we prepared asymmetric membranes incorporatingcross-linked 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) hydrogel by combining photopolymerization and liquid phase inversion. An experimental design measuring water content and ion-exchange capacity of these membranes was used to select the optimal membrane composition for the removal of Pb2+, Ni2+, and Cd2+ ions from aqueous solutions. The results demonstrated fast sorption kinetics and high capacity for the investigated metals.

AB  - Affinity-based devices utilizing plasmonic effects belong to the most sensitive chemical sensors. A membrane having a form which coincides with the distribution of surface electromagnetic waves coupled with collective oscillations of electron gas in the conductive part of the sensor represents an important building block for plasmonics. A way to boost selectivity of a plasmonic sensor is to functionalize such membrane and either to apply it on the sensor surface or even to use it as a stand-alone platform for sensing. In this work we considered a possibility to prepare multifunctional membranes for plasmonic sensing. In our experiments selectivity enhancement was achieved through the use of glycidyl methacrylate whose epoxy group is readily converted to a desired affinity group (e.g. amine, thiol, pyridine, dithiocarbamate) to preferently capture a targeted species. Further plasmonic functionalization was obtained by forming a thin hydrogel film through copolymerization of glycidyl methacrylate with mono- and multi-functional methacrylates and then incorporating silver nanoparticles within these nanocomposites. These plasmonic nanoparticles were produced either photochemically or by chemical reduction. Different schemes for plasmonic sensor selectivity enhancement using multifunctionalized glycidyl methacrylate membranes are considered.

AB  - Plasmonics is the basis for a novel generation of adsorption-based ultrasensitive (bio) chemical sensors. In nanoplasmonic sensors one utilizes nanocomposites typically in the form of thin films, comprising metal nanoparticles or ordered metal-dielectrics (plasmonic crystals). In this work we investigated thin functionalized hydrogel films with embedded silver nanoparticles. These films were prepared by copolymerizing glycidyl methacrylate with mono and multifunctional methacrylates using UV irradiation. The epoxy group in glycidyl methacrylate can then be converted by chemical means into a desired functionality to capture the targeted analyte. Silver nanoparticles were either photochemically generated in situ, or were introduced into hydrogels by chemical reduction. Differences in morphology and performance of these nanocomposites were investigated andwill be discussed.

AB  - We considered the possibility to fabricate multifunctional nanocomposite membranes as a platform for plasmonic metamaterials, simultaneously incorporating pores, built-in functional groups and active nanoparticles. To this purpose we combined lamination and inclusion of nanofillers into the membrane host. For the basic material we chose macroporous crosslinked copolymers based on glycidyl methacrylate (GMA). The epoxy group present in GMA molecule is readily transformed into various functional groups that further serve as affinity enhancers, ensuring the usability of the membranes as pre-concentrators of selected agents in plasmonic sensors. To form GMA-based membranes we used a recently proposed method combining the traditional immersion precipitation with photopolymerization and crosslinking of functional monomers. Further functionalization is obtained by in-situ formation of noble metal nanoparticles directly within the GMA host. In this way membranes with simultaneous plasmonic, adsorbent and catalytic functionality are obtained. We considered the use of the our structures for plasmonic chemical sensors where separator, pre-concentrator and binding agent are integrated with the plasmonic crystal, as well as for plasmonic enhancement of photocatalytic reactions in microreactors. Our approach gives a highly tailorable element compatible with microelectromechanical systems (MEMS) technologies and readily transferable across platforms.

AB  - Ultrafiltration has recently become popular as a promising separation method in many industrial processes covering fractionation and concentration steps in the food, pharmaceutical and biotechnology industries as much as in water and wastewater treatments. This paper presents the synthesis of novel asymmetric polyethersulfone membranes containing an interpenetrating network of poly(glycidyl methacrylate) (PGMA). In order to improve the properties and application range of membranes, the epoxy groups from PGMA are converted to amine groups by ring opening under alkaline conditions. Membranes before and after functionalization are characterized by FTIR-ATR, elememtal analysis and water permeability.

AB  - One of the important applications of subwavelength plasmonic optics is sensing of chemical and biological analytes [1]. Plasmonic sensors are based on tuning of either propagating surface waves (surface plasmon polaritons, SPP) or nonpropagating (localized) ones. The adsorption of analyte modifies the surface refractive index, ensuring ultrahigh sensitivities that may exceed 10–8 refractive index units, i.e. 1 ng/cm2 (0.003 monolayer) [2]. For all plasmonic sensors it is of interest to enhance their selectivity, since their operation is based solely on refractive index sensing, i.e. different materials with similar refractive indexes cause similar outputs. In this work we propose the integration of active plasmonic part with separator (e.g. membrane or nanomembrane with nanopores) and ligand binding the targeted analyte into a single structure. This may be done by membrane nanocompositing [3], e.g. by lamination (Fig. 1a) or volume structuring/pore formation (Fig. 1b). At the same one may use built-in (nano)pores to augment the effective surface for adsorption and thus vastly increase the amount of adsorbate. For our work we chose macroporous crosslinked copolymers (MCP) which are readily formed into membranes and keep a permanent well-developed porous structure. Particularly we used glycidyl methacrylate (GMA)-based MCP. GMA has already been successfully used for heavy and precious metals adsorption and enzyme immobilization [4]. For the formation of membranes comprising GMA we selected a new method combining traditional immersion precipitation with photopolymerization and crosslinking of functional monomers [5]. Our approach may be extended to other types of chemical and bio sensors.
