Numerous plants are recognized for their phytotoxic and inhibitory influence on growth of cultivated crops. This study was conducted to probe the allelopathic effect of Calotropis procera water extract on the seed germination and seedling vigor of wheat. C. procera extract with 1:20 w/v concentration was applied on th…
Two dimensional metallic photonic band gap (PBG) structures, which have higher power handling capability, have been analyzed for their dispersion characteristics. The analysis has been performed using flnite difierence time domain (FDTD) method based on the regular orthogonal Yee's cell. A simplifled unit cell of tria…
Thermal manikins were created with the intention to design and model protective clothing insulation for specific conditions, e.g. military clothing and clothing for divers. At present thermal manikins have a broader use, i.e. to assess the effect of clothing on a human body, to assess its influence on thermal comfort…
We studied radical polymerization in methyl methacrylate solution with methyl pheophorbide a and its copper complex. We have shown the possibility of controlled synthesis of copolymers with controllable molecular weight characteristics when reaction medium parameters are varied. We have established that the compositio…
We present an overview of laser methods for nanostructuring of surfaces that are in the focus of ongoing research activities of our Institute (LP3). The methods imply the removal of material by laser radiation to provide either spontaneous nanostructuring of laser–illuminated surface or its controlled nano–modificatio…
Three nanostructured platinum-niobium supported on Vulcan XC-72R carbon black materials were prepared as catalysts for the ethanol electroxidation: (i) deposition of platinum and niobium on Vulcan XC-72R carbon black, (ii) platinum decorated on a mixture of commercial amorphous Nb 2 O 5 /carbon black, and (iii) the sa…
The MIAplex® device is a miniaturized detector, devoted to the high sensitive detection of superparamagnetic nanoprobes for multiparametric immunoassays. It measures a signal corresponding to the second derivative of the magnetization around zero field. Like any new technology, the real success of the MIAplex® detecto…
The objective of the present study was to investigate the use of propranolol-magnesium aluminium silicate intercalated complexes as drug reservoirs in hydroxypropylmethylcellulose tablets. The matrix tablets containing the complexes were prepared and characterised with respect to propranolol release and were subsequen…
This study investigated the degradation mechanism of Ti substrate-based dye-sensitized solar cells (DSSCs) after a thermal aging test. The deteriorated component of Ti-based DSSCs was clarified by chemical impedance spectroscopy and scanning electron microscope. This indicated that an unfavorable reaction occurred on…
The present contribution gives an overview about recent research on a thermal barrier coating (TBC) system consisted of (i) an intermetallic MCrAlY-alloy Bondcoat (BC) applied by vacuum plasma spraying (VPS) and (ii) an Yttria Stabilised Zirconia (YSZ) top coat air plasma sprayed (APS) at Forschungszentrum Juelich, In…
We report for the first time the multi-gram scale solution growth of α-aluminium fluoride trihydrate (α-AlF3·3H2O) nanorods (NRs) under low supersaturation conditions, and their conversion to porous β-AlF3 NRs. Electron microscopy analysis shows that the NRs yielded from the optimized conditions have an average length…
The formation mechanism of the sub-block microstructure in lath martensite is explained by a two-type-slip deformation (TTSD) model. To simulate the sub-block structure morphology, the TTSD model is coupled with the phase field method resulting in the elastoplastic phase field model. The sub-block structure of lath ma…
The objective of the present study was to simultaneously evaluate the effect of a postharvest treatment on the pepper's antioxidant content and its ability to retain its economical value during the postharvest period. The fruits were pretreated by modified atmosphere packaging (MAP) with or without treatment with 1-me…
Using epifluorescence microscopy, the configuration of myelin figures that are formed upon hydration of lipid stack was studied qualitatively. Little knowledge is currently available for conditions that determine the diameter of myelin figures and their degree of multilamellarity. Examining more than 300 samples, we r…
Physical vapor deposition of tin-doped lead selenide (Sn/PbSe) thin films on SiO2glass is described. Interaction of high-energy Ar+ions bombardment on the doped PbSe films is discussed by XRD analysis. The improvement of optical band gap of Sn/PbSe films irradiated by different doses of irradiation was studied using t…
We report on a new route for creating multi-component micelles employing a specifically designed triblock copolymer, C18PEG10-block-NIPAAM54-block-(AMPTMA(+))16, combining hydrophobic and hydrophilic segments as well as a polyelectrolyte end block. By interaction with an oppositely charged surfactant (SDS), the block…
Scanning electrochemical microscopy (SECM) experiments were undertaken to study the EC ' mechanism, e.g. where a product of the electrode reaction reacts to regenerate the starting material. Digital simulations of the two dimensional SECM were carried out and the results tested with the known EC ' system of Fe(CN) 6 4…
The Self Excited Induction Generator (SEIG) is an isolated power source whose terminal voltage and frequency are controlled by the excitation of the capacitance or the load impedance. This paper presents a method for calculating the minimum excitation capacitance using the equivalent circuit approach for analyzing the…
This preliminary research project has been conducted to evaluate different elastic polymer materials in terms of their applicability in peripheral nerve regeneration. Poly(tetrafluoroetylene-co-difluorovinylidene-co-propylene), poly(L-lactide-co-D,L-lactide), and polyurethane were used for the manufacture of tubular i…
A detailed computational study on the reaction mechanisms of the thermal activation of methane by the bare complex [Ni(H)(OH)](+) has been conducted. The experimentally observed reaction features, i.e. the ligand exchange Ni(H) → Ni(CH(3)), the H/D scrambling between the incoming methane and the hydrido ligand of the…
