Forced Periodic Operation of Methanol Synthesis in an Isothermal Gradientless Reactor
(Wiley, 2022)
Methanol synthesis from synthesis gas with heterogeneous Cu/ZnO/Al2O3 catalysts in an isothermal gradientless reactor is described. In a theoretical study, the potential of forced periodic operation (FPO) for improving ...
Three Types of Films from Liquid-phase-exfoliated Graphene for Use as Humidity Sensors and Respiration Monitors
(MYU K.K., 2022)
Measuring relative humidity is important for a myriad of industries, including production, agriculture, environmental monitoring, and medicine. Thin-film, fast-response sensors are particularly interesting for wearable ...
Synthesis of the new lost foam refractory coatings based on talc / Синтеза нових “lost foam” ватросталних премаза на бази талка
(Journal of the Serbian Chemical Society, 2022)
This paper is focused on the preparation procedures, using a talc-based filler, to improve the rheologic properties of the lost foam refractory coatings. Talc, with grain size of 40 .m, was mechanically activated in a ...
PS-BBICS: Pulse stretching bulk built-in current sensor for on-chip measurement of single event transients
(Elsevier, 2022)
The bulk built-in current sensor (BBICS) is a cost-effective solution for detection of energetic particle strikes in integrated circuits. With an appropriate number of BBICSs distributed across the chip, the soft error ...
Ultra wideband bandpass filters with specified relative bandwidth
(Berlin : Walter de Gruyter GmbH, 2022)
Algorithm for the realization of the broad range of values of wide relative bandwidth (RBW) bandpass filter is introduced. Algorithm is based on periodic ideal cells each with short-ended stub. Theory is developed for a ...
Supercapacitive properties of the alkali metal hydroxides-activated carbons obtained from sucrose / Суперкапацитативна својства угљеничних материјала добијених из сахарозе и активираних хидроксидима алкалних метала
(Belgrade : Serbian Chemical Society, 2022)
The influence of different hydroxides, applied to activate carbon black, on the electrochemical properties of activated carbon was investigated. The carbon material was prepared by hydrothermal treatment of sucrose and ...
Novel composite based on zirconia and graphite. First results of application for synthetic dyes removal
(Universitatea Babes-Bolyai, Catedra de Filosofie Sistematica, 2022)
In this research composite based on zirconia and graphite was synthesized using the sol-gel method. Aim of this research is to activate and increase the photocatalytic activity of ZrO2 by combining with graphite-based ...
Comparison of non-destructive techniques and conventionally used spectrometric techniques for determination of elements in plant samples (coniferous leaves) / Поређење недеструктивних и конвенционално коришћених спектометријских техника за одређивање елемената у биљном материјалу (иглице четинара)
(Journal of the Serbian Chemical Society, 2022)
Conventionally used spectrometric techniques of inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma optical emission spectrometry (ICP-MS) usually involve time-consuming sample ...
Star-shaped poly(ε-caprolactones) with well-defined architecture as potential drug carriers / Разгранати поли (ε-капролактони) са добро одређеном архитектуром као потенцијални носачи лекова
(Serbia : Serbian Chemical Society, 2022)
The present study reports the potential application of star-shaped poly(ε-caprolactones) with different number of arms as new drug delivery matrix. Linear and star-shaped PCL ibuprofen loaded microspheres were prepared ...
Enhancing mechanical properties of 3D printed thermoplastic polymers by annealing in moulds
(SAGE, 2022)
Five series of specimens with two different print orientations (−45/45 and 0/90) and two print layer thicknesses (0.1 and 0.2 mm) were made. In total 60 specimens with 100% filament infill were made. One specimen series ...
