We report the structure of an aluminum borohydride ethylenediamine complex, Al(EDA) 3 ·3BH 4 ·EDA. This structure was successfully determined using X-ray powder diffraction and was supported by first-principles calculations. The complex can be described as a mononuclear complex exhibiting three-dimensional supramolecu…
Inversion layer technique can increase the centre frequency ( f 0 ) and the −6 dB bandwidth of the ultrasound transducer without reducing thickness of active material. However, it suffers from the reduced −6 dB bandwidth when the centre frequency is increased more than 1.5 f 0 . A modified inversion technique is propo…
Fabrication of fluoride phosphate glass optical fibers using the extrusion method for preform fabrication has been studied using the commercial Schott N‐FK51A glass. The extrusion step was found to create a surface layer of differing composition from the bulk glass material, leading to defects drawn down onto the opti…
With the aid of 2D computer simulations, the whole colloidal crystallization process for particles interacting with a short-ranged attractive potential is described, emphazising the visualization of the different subprocesses at the particle level. Starting with a supercooled homogeneous fluid, the system undergoes a…
Stable alkenyl succinic anhydride (ASA) emulsions with approximately 25% of ASA were prepared by using native maize starch and laponite particles as stabilizers. The morphology, sizing performance, and storage stability of the as-prepared ASA emulsions were evaluated. It was surprisingly found that the introduction of…
Interplay between a charge density wave (CDW) and superconductivity in LaPt2(Si1-x Ge x )2 has been studied by electrical transport and magnetic measurements. LaPt2Si2 crystallizes in CaBe2Ge2 type structure which shows a first order structural phase transition from tetragonal to orthorhombic accompanied by a CDW tran…
This paper proposes a new design paradigm which allows for a modular approach to replacing a homogeneous optical lens system with a higher-performance GRadient-INdex (GRIN) lens system using a WaveFront Matching (WFM) method. In multi-lens GRIN systems, a full-system-optimization approach can be challenging due to the…
A simple and effective decoupled finite element analysis method was developed for simulating both the piezoelectric and flexoelectric effects of zinc oxide (ZnO) and barium titanate (BTO) nanowires (NWs). The piezoelectric potential distribution on a ZnO NW was calculated under three deformation conditions (cantilever…
The use of vegetable oils to replace fossil feedstock has become an area of opportunity and a priority for study in the field of polymer science. Vegetable oils are considered as renewable resources with high potential, low c... | Find, read and cite all the research you need on Tech Science Press
This paper demonstrates the possible usage of TiOx thin films synthesized by atomic layer deposition as a microbolometer active material. Thin film electrical resistance is investigated as a function of thermal annealing. It is found that the temperature coefficient of resistance values can be controlled by coating/an…
We study multiple tearing of a thin, elastic, brittle sheet indented with a rigid cone. The n cracks initially prepared symmetrically propagate radially for n≥4. However, if n<4 the radial symmetry is broken and fractures spontaneously intertwine along logarithmic spiral paths, respecting order n rotational symmetry.…
A novel strategy named pulsed propylene method was developed to prepare fine grained SiC layer. The SiC layer was uniformly coated on ceramic microspheres by fluidized bed chemical vapor deposition. Propylene was introduced into the deposition system in pulsed form at proper time intervals. By adjusting the propylene…
The cold plasma techniques are widely applied to create new materials possessing unique properties, which cannot be prepared by any other methods. Among the many interesting substances produced with the participation of cold plasma, a special place is occupied by materials with catalytic properties. The chapter gives…
Nowadays many techniques are used for the surface modification of fabrics and textiles. Two fundamental techniques based on vacuum deposition are known as chemical vapor deposition (CVD) and physical vapor deposition (PVD). In this chapter, the effect of plasma-enhanced physical and chemical vapor deposition on textil…
Aliphatic chains were introduced into the macromolecule of kraft lignin using aliphatic chlorides as esterification reagents. The hydrophobicity of esterified lignin (EL) was enhanced as compared to the original lignin. EL was further used as a macromolecular coupling agent in poly(butylene succinate)/chemi-thermomech…
A series of quinoline-labeled water-soluble copolymers, synthesized through free radical copolymerization of vinyl-modified quinoline derivatives with water-soluble monomers such as the nonionic N, N -dimethylacrylamide (DMAM), the anionic sodium 2-acrylamidomethylpropanesulfonate (AMPSNa), and the cationic methacryla…
This study is focused on structural changes induced by increasing treatment temperature of sol‐gel–derived La 2 O 3 ∙Al 2 O 3 ∙Ga 2 O 3 ∙5B 2 O 3 system. The structure of samples heated for 30 min up to 900°C was investigated by X‐ray diffraction ( XRD ), Fourier transform infrared ( FTIR ) spectroscopy, and magic‐ang…
Food safety is becoming an increasing concern in the United States. This study investigated the effects of ultraviolet-C (UV-C) light as a postpackaging bactericidal treatment on the quality of English cucumber packaged in polyethylene (PE) film. Escherichia coli k-12 was used as a surrogate microbe. The microbial gro…
OBJECTIVES: As a parenchymal cell, the photoreceptor is more susceptible to alterations in outer micro-environmental conditions than other cells. In the present study, we aimed to investigate inhibitory effects of zinc oxide (ZnO) nanoparticles on expression of manganese superoxide dismutase (MnSOD) in murine photorec…
A novel triazine oligoimides containing silicone charring agent (TSCA) was prepared and used as charring agents in poly(ethylene terephthalate) (PET)/hexakis (4‐phenoxy) cyclotriphosphazene (PNCP) flame retardant system. Limited oxygen index, microscale combustion calorimetry, thermogravimetric analyses, and environme…
