Microstructural, thermo-optical, mechanical and tribological behaviours of vacuum heat treated ultra thin SS304 foils, Palai, Debajyoti, Bhattacharya, Manjima, Mallick, Amitava Basu, Bera, Parthasarathi, Sharma, Anand Kumar, Mukhopadhyay, Anoop Kumar, Dey, Arjun
The device performances of an amorphous indium gallium zinc oxide transparent thin-film transistor (a-IGZO TFT) were improved by using a Ti-doped GaZnO (GTZO) as the channel capping layer in this study. The GTZO thin film exhibited a high carrier concentration of 1.5 × 1021cm-3and served as both a carrier supplement a…
Carbon nanotubes (CNTs) may be useful due to their sound thermo-mechanical properties. The present work deals with the evaluation and analysis of elastic properties and coefficient of thermal expansions (CTEs) of a CNTs-based 2D plane woven fabric composite material system where the CNTs are radially grown on the surf…
Выполнено исследование композитов Al/НС, Ni/НС, Ti/НС и Ni/Al/HC, полученных методом низкотемпературной ионной имплантации нержавеющей стали (НС). Синтезированные композиты изучены методами традиционного рентгеноструктурного анализа, рентгеноструктурного анализа тонких плёнок, рентгеновской фотоэлектронной спектроскоп…
Recent research in the field of gecko-inspired dry adhesive has focused on modifying the material and structural properties of polymer-based nanohairs. Polymers such as polystyrene (PS), high-density polyethylene (HDPE), ultraviolet curable epoxy (SU-8), polyurethane acrylate (PUA), polycarbonate (PC), and polydimethy…
The aim of this study is to design a spinneret that can be used efficiently for the manufacturing of coaxial composite filaments. Poly(ethylene terephthalate) was used as resin matrix with 99.9% pure copper filament as the core. The characterization of the polymer was done to determine polymer thermal and rheological…
Bulk metallic glass (BMG) and BMG-graphite composites were fabricated using spark plasma sintering at the sintering temperature of 575 °C and holding time of 15 min. The sintered composites exhibited partial crystallization and the presence of distributed porosity and graphite particles. The effect of graphite reinfor…
Abstract A new approach for the enzymatic synthesis of methyl β-d-glucoside was proposed, based on commercially available cellulase and cellulose pretreated with phosphonium-based amino acid ionic liquid/cosolvent. The pretreatments were quite effective and methyl β-d-glucoside was successfully synthesized with 40% yi…
The structural, elastic, electronic, and optical properties of BaCuO2 are investigated using the plane-wave ultrasoft pseudo-potential technique, which is based on the first-principle density functional theory (DFT) with generalized gradient approximation (GGA). The calculated structural parameters show a good agreeme…
The thickening behavior and synergistic mechanism of the mixed system of the hydrophobically associating polymer (HAP-S) (acrylamide/acrylate-EOm-POn/sodium acrylate terpolymer) with small molecular weight and the acrylamide/N-isooctyl acrylamide/sodium acrylate terpolymer (HAP-L) with large molecular weight were inve…
Cracking due to corrosion in bed joint reinforcement over openings in masonry facades in the Scandinavian post-war building stock generates increasing retrofitting needs. Removal of the reinforcement can be both costly and labor intensive. The results of retrofitting works are often sub-optimal due to casual inspectio…
Thermal vibration of a rectangular single-layered graphene sheet (RSLGS) with initial stress is investigated by a semiquantum molecular dynamics (SQMD) method on the basis of modified Langevin dynamics. The quantum effect in the thermal vibration of RSLGS is accounted by introducing a quantum thermal bath. The spectru…
This investigation focuses on the study of the solidification mechanism of compacted graphite cast iron (CGI). The solidification macrostructure was revealed in cast samples using a special technique known as direct austempering after solidification (DAAS). The microstructure was revealed by colour etching. The result…
The encapsulation of Altretamine (ALT) and Thiotepa (THI) as neurotoxic anticancer drugs in Cucurbit[[Formula: see text]]uril (CB[[Formula: see text]]) family of macrocycles ([Formula: see text],8) have been investigated and their potential in drug delivery, ability to provide physical and chemical stability, improvin…
Poly(vinyl alcohol) (PVA)/powdered ethyl acrylate rubber (ACM) composite hydrogels were prepared through in situ chemical cross-linking. The addition of ACM could accelerate the cross-linking reaction of PVA, and increase pore nucleus, resulting in a decrease of pore size and formation of a homogeneous and compact por…
In the interfacial superconductor Bi2Te3/Fe1+yTe, two dimensional superconductivity occurs in direct vicinity to the surface state of a topological insulator. If this state were to become involved in superconductivity, under certain conditions a topological superconducting state could be formed, which is of high inter…
New polymeric cadmium complexes, α-[CdLCl2]n (1), [CdL2Cl2]n (2) and β-[CdLCl2]n (3) (L = 4-amino-2,1,3-benzothiadiazole), were obtained as products of the reaction of CdCl2 with L. The synthetic procedures allowing isolation of pure 1–3 were optimized. The structures of 1–3 were established by single-crystal X-ray di…
Nucleation and growth mechanisms in Co, Cu, and Co x Cu 100– x single films, and in Co x Cu 100– x /Cu bilayers, electrodeposited on Cu 70 Zn 30 brass substrates, are studied by the constant potential technique. The recorded current–time transients (CTTs) are rather complex, and they extend for long times. Co, Cu, and…
SnO2 is an attractive anode material for lithium-ion batteries (LIBs) due to its high theoretical specific capacity (1491 mAh g(-1)), low cost, and environmental benignity. The main challenges for SnO2 anodes are their low intrinsic conductivity and poor cycling stability associated with their large volume changes dur…
Nonradiative recombination is one of the key electronic processes in semiconductor devices. In this study, we demonstrate that nonradiative recombination rate of intermolecular charge-transfer (CT) exciton at organic heterojunction increases exponentially with decreasing energy difference between the LUMO of acceptor…
