In this era of plastics dominated world, it remains a fact that there exists an everincreasing margin between the volume of waste plastics generated and the volume recycled [1]. Of the total plastic waste, recyclable thermoplastics like polyethylene, polystyrene, polypropylene and PVC account for nearly 78% of the tot…
In this work single crystal fiber growth by the micro-pulling-down technique and the structural and spectroscopic characterizations of undoped and Nd3+-doped double molybdate LiLa(MoO4)2 are reported. The optimization of the growth conditions was studied in order to avoid facet formation. The grown fibers are free of…
We describe the design and synthesis of ferrocene dimers and trimers bridged by an oligothiophene spacer as both cathodic and anodic multiple redox-active organic–organometallic hybrid molecules. The electrochemical properties of all compounds were examined by cyclic voltammetry (CV). The voltammograms showed differen…
Sometimes polymer layer was coated on gold later for detection and improvement the sensor performence. So, the properties of nanostructures gave rised to interest in biosensing. Nano particles and Nano tube have improved the sensitivity, selectivity, and multiplexing capacity in biosensors. Different types of nanostru…
A new hybrid pyrazine-terpyridine ligand L (C(34)H(22)N(8)) and its complexes with different transition metal ions, M (M = Mn(II) 1, Zn(II) 2, Fe(II) 3, Co(II) 4, Cu(II) 5 and Cd(II) 6), have been synthesised. In the presence of a nitrate counter-anion, both Cu(II) and Cd(II) give complexes in which the ratio M:L is 2…
By the early 90s, K. S. Suslick had developed a method using high-intensity ultrasound to make aqueous suspensions of proteinaceous microcapsules filled with water-insoluble liquids. This method was extended on the one hand to include (instead of proteins) starch, chitosan, DNA, RNA, PEG, and more. The second directio…
Jack bean (Canavalia ensiformis) is the source of interesting proteins that contribute to modern biochemistry, and urease is the primary of these proteins. Owing to its role and occurrence in nature, urease has become a part of extensive studies. In this study, jack bean urease (JBU) was purified by immobilized metal…
The deparation of phenylalanine (Phe) enantiomers by reactive liquid–liquid extraction with (s)-BINAP-metal complexes as enantioselective extractants was investigated. Metal complexes formed by different central ions with (s)-BINAP as a ligand were used as chiral extractants, among which the CuPF 6 -(s)-BINAP complex…
We propose a general approach that allows one to reveal factors causing production errors in the course of the deposition process controlled by broadband optical monitoring. We consider computational experiments simulating the real deposition process as a crucial point of this approach. We demonstrate application of t…
The study of propagating surface plasmons (PSPs) is an important aspect of the understanding of the interaction between light and metallic surfaces. One of the key concepts related to PSPs, is the dispersion relation. This relation is the basis for understanding of coupling of light to PSPs, by using special approache…
High-density wood is required in wood flooring, especially in engineered wood flooring (EWF) designed for heavy-duty applications. However, high-density wood resources are limited and their cost is high. A densification treatment makes it possible for low- or moderate-density woods to replace harder species by modifyi…
Nd:YAG lasers with output power levels of tens of watts, a nearly diffraction-limited beam quality, and a linearly polarized continuous wave output are commonly pumped by laser diodes at a wavelength around 808 nm, where the pump light spectrum is matched well to the absorption maximum of Nd:YAG. As a consequence, low…
We demonstrate that mercury and antimony compounds with chalcogens (Q = S, Se, Te) and halogens (X = I, Cl, Br) can be a promising family for radiation detection materials. Chalcogen p-orbitals are usually located near the Fermi level and they are responsible for relative high mobilities but at the same time band gap…
Single crystals of Ln(2)Fe(4)Sb(5) (Ln = La-Nd and Sm) were grown from an inert Bi flux. Measurements of the single crystal X-ray diffraction revealed that these compounds crystallize in the tetragonal space group I4/mmm with lattice parameters of a ≈ 4 Å, c ≈ 26 Å, V ≈ 500 Å(3), and Z = 2. This crystal structure cons…
Jenseits von Eisentrifluorid: Matrixisolations-IR-Spektroskopie und hochgenaue quantenchemische Rechnungen ermöglichten die Charakterisierung von Eisentetrafluorid, einer bislang unbekannten Spezies. FeF4 wurde bei kryogenen Temperaturen durch Coabscheidung von Fluor und mithilfe von Laserstrahlung verdampften Eisenat…
This work reports on the dc performance of AlGaN/GaN metal-oxide-semiconductor high electron mobility transistors (MOSHEMTs) grown on Si (1 1 1) substrate and the study of current dispersion in these devices using various widely adopted methods. The MOSHEMTs were fabricated using a very thin (4.2 nm) SiO 2 film as the…
Navy blue crystals of a two-coordinate homoleptic palladium complex with two phosphinyl radical ligands was synthesized by a simple ligand-exchange reaction. Significant π interactions between orbitals of Pd and the SOMO of phosphinyl radicals are responsible for the diamagnetic character, the intense blue color, and…
This paper deals with the product design, engineering, and material selection intended for the manufacturing of an eco-friendly chair. The final product is expected to combine design attributes with technical and legal feasibility with the implementation of new bio-based materials. Considering the industrial design, a…
We have demonstrated cost-effective ITO-free polymer solar cells (PSCs) with ink-jet-printed current collecting Ag grids in combination with highly conductive PEDOT:PSS as a composite transparent electrode. By ink-jetting of Ag nano-particle solution, we were able to obtain ink-jet-printed Ag grids with sheet resistan…
We investigate the influence of temperature on the self-assembly of 2,6,11-tricarboxydecyloxy-3,7,10-triundecyloxy triphenylene (asym-TTT) adsorbed on HOPG using scanning tunneling microscopy (STM) at the liquid/solid interface. We show that the packing structures of 2D self-assembled asym-TTT can be precisely tuned b…
