Dynamic transformation from a one-dimensional water tape (2T6(2)) with a boat conformation, one-dimensional water chain, to no water was observed in a benzoimidazole-based nonporous organic solid, which shows a non-linear optics and luminescence response upon one-dimensional water removal and uptake.
Fifty years ago, one of the worldwide first industrial production processes to produce fission-Mo-99 for medical use had been started at ZfK Rossendorf (now: HZDR, Germany). On the occasion of this anniversary, it is worth to mention that this original process (called LITEMOL now) together with its target concept used…
Groundwater in the Eastern Croatia, as well in the South-eastern Hungary, contains relatively high concentrations of arsenic that can cause chronic toxicity to humans. Therefore, the aim to find an effective composite adsorbent that can be applied for arsenic water remediation by introducing it in the groundwater trea…
Poly(3-hexylthiophene)-functionalized siloxane nanoparticles were prepared by a modified Stöber method. The photovoltaic performance of P3HT-nanohybrids with C60 derivative PCBM was evaluated. The device made from 1 : 1 blends of P3HT-NPs:PCBM showed reasonably good photovoltaic performance with a power conversion eff…
A comparison study on the performance characteristics and surface characterization of two different solid-contact selective potentiometric thrombin aptasensors, one exploiting a network of single-walled carbon nanotubes (SWCNTs) and the other the polyaniline (PANI), both acting as a transducing element, is described i…
Because of the significantly-increasing work-function variation (WFV) in high-k/metal-gate technology in sub-30-nm nodes, a simple but reasonable model for quantitatively estimating the WFV is currently required. In this study, a Monte Carlo simulation for statistically generating the grain sizes following two differe…
Based on the confinement effect of the CB[8] cavity, a new strategy for explosives detection was developed by using a naphthalene embedded CB[8] complex as receptor. It was found that, dependent on the electronic structures and size of the tested explosives, the trapping of such analytes can significantly influence th…
Functional nontoxic cadmium telluride (CdTe) quantum dots (QDs) have been synthesized using a natural functional glycolipid belonging to the family of sophorolipids (SL) as a surface-modifying agent.
The separation performance of a polymeric-supported hybrid silica membrane in the dehydration process of a butanol–water mixture at 95 °C has been enhanced by applying a bias to the substrate during the plasma deposition.
Controlled release formulations for local, in vivo drug delivery are of growing interest to device manufacturers, research scientists, and clinicians; however, most research characterizing controlled release formulations occurs in vitro because the spatial and temporal distribution of drug delivery is difficult to mea…
We present an experimental investigation of the dynamics of rod impact on bare or uncovered PBX 9501 explosive. By weight, PBX 9501 contains 95% octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine, commonly known as HMX. The plastic binder is Estane combined with a nitro-plasticizer made of bis(2,2-dinitropropyl)acetal a…
The structural preferences of nanoparticles are important for understanding their chemical properties and potential applications, and remain widely debated. Based on recent experimental observations, we present calculations on the stability of high-symmetry AuN and PdN clusters of various structural motifs, performing…
Topological surface states, while protected by time-reversal symmetry in the bulk limit, can be missing in films with thicknesses much greater than the decay lengths of the surface states. This novel effect is demonstrated theoretically in Bi2Se3, the best known topological insulator. When the spin-orbit-coupling stre…
We have prepared the (5-chloro-quinolin-8-yloxy) acetic acid and characterized it by using infrared, Raman and multi-dimensional nuclear magnetic resonance spectroscopies. The density functional theory (DFT) together with the 6-31G* and 6-311++G** basis sets were used to study its structure and vibrational properties.…
In this work, aluminium-doped zinc oxide (AZO) was deposited via RF magnetron sputtering on glass substrates having different surface energies at room temperature. The different surface energies were developed by passivation of alkylsilane self-assembled monolayers (SAMs) with various hydrocarbon chain lengths on subs…
Radial heterojunction photodiodes based on a silicon nanowire arrays (SiNWs)-zinc oxide (ZnO) core-shell structure is demonstrated in this report. The heterojunction can be constructed by spin-coating ZnO nanoparticles onto SiNWs and a low temperature post-annealing process (<270 °C). The photodiode displays typical d…
Al-Cr-Fe coatings have been widely used in the surface engineering field of materials, due to their excellent corrosion resistance to water vapor and fused salt deposits. In this study, a new two-step approach was developed to prepare Al-Cr-Fe coatings on surfaces of SUS430 stainless steels. First, the Cr/Al composite…
Photoelectrodes were used to treat synthetic textile wastewater contaminated with indanthrene blue dye. Two media of treatment were used (NaCl and Na2SO4), with variations on temperature, pH, current density, dye and chloride concentration. A modified Pechini method was applied to obtain Ti/Ru-based electrodes (Ti, Ru…
Single-crystalline wurtzite ZnS nanobelts exhibiting enhanced narrow band-edge luminescence at room temperature have been synthesized readily through a one-step mild hydrothermal process involving ternary solvents of hydrazine, ethylenediamine, and water.
This study investigated the regeneration of waste edible oil using a food additive (calcium silicate, CAS). Waste edible oil was prepared by combined heat and aeration treatment. Moreover, the deterioration of edible oil by combined heat and aeration treatment was greater than that by heat treatment alone. The acid va…
