Thermal properties of poly(urethane-ester-siloxane)s based on hyperbranched polyester
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Novel polyurethanes (PUs) were synthesized using hydroxy-terminated hyperbranched polyester (BH-20) and 4,4'-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxy-terminated ethylene oxide-poly(dimethylsiloxa ...
A trapezoidal microstrip bandstop filter with efficient suppression of undesired stopbands
(National Institute of Optoelectronics, 2010)
A new bandstop filter implemented as a cascade of trapezoidally shaped cells is presented. The proposed bandstop filter suppresses many undesired stopbands at higher frequencies. The cell design is specified by two variables ...
New Experimental and Mechanistic Investigation on the KSCN-H2O2-NaOH-Cu(II)-Catalyzed Oscillating System (Orban-Epstein Reaction): Inhibitory Effects by Diphenols
(Wiley-Blackwell, Hoboken, 2015)
The KSCN-H2O2-NaOH-Cu(II)-catalyzed system is one of the few reactions in which chemical oscillations can be observed in batch conditions. In the present paper, this oscillating reaction was revisited in a wide range of ...
High Activity and Stability of Pt2Bi Catalyst in Formic Acid Oxidation
(Springer, New York, 2012)
Formic acid oxidation was studied on a new prepared Pt2Bi characterized by X-ray diffraction spectroscopy (phase composition), scanning tunneling microscopy (STM) (surface morphology), and COads stripping voltammetry ...
P-nitrophenol electro-oxidation on a btma(+)-bentonite-modified electrode
(Clay Minerals Soc, Chantilly, 2012)
Phenol and its derivatives arc regarded as 'priority pollutants' and p-nitrophenol (p-NP), in particular, is of great interest due to its toxicity and frequent presence in waste waters and fresh waters. Straightforward, ...
Atomic partial charges for mixed chloroammine chromium(III) complexes fitted to the molecular electrostatic potential
(Elsevier, 2012)
Using the RESP procedure partial atomic charges for six isomers of a series of octahedral complexes [Cr(NH3)(6-x)(Cl)(x)]((3-x)+) (x = 0, 1, 2, 3) were least-square fitted to the molecular electrostatic potential (MEP) ...
Ring- and side-group conformational properties of di-O-acylated xylopyranosides: A computational study
(Elsevier, 2015)
The conformational properties (C-4(1), C-1(4), and skew ring structures, side chain torsion) of methyl 2,4-(1) and 3,4-O-diacetyl (2) as well as 2,4-(3) and 3,4-O-dibenzoyl (4)-SS-D-xylopyranoside are calculated by ...
A second-order nonlinear model of monolayer adsorption in refractometric chemical sensors and biosensors case of equilibrium fluctuations
(Springer, Dordrecht, 2016)
In adsorption-based chemical and biological refractometric sensors the dependence of the refractive index of the sensing area on the number of adsorbed particles is used for detection and quantification of analytes. We ...
Low-pass filter with deep and wide stop band and controllable rejection bandwidth
(Cambridge Univ Press, Cambridge, 2015)
Novel design of low-pass microwave filters based on cascading of identical unit cells is proposed. Dispersion relation is used to determine the cell parameters for a given relative stop-band width. For a filter consisting ...
Analysis of solid waste from ships and modeling of its generation on the river Danube in Serbia
(Sage Publications Ltd, London, 2013)
This study focuses on the issues related to the waste management in river ports in general and, particularly, in ports on the river Danube's flow through Serbia. The ports of Apatin, Bezdan, Backa Palanka, Novi Sad, Belgrade, ...
