Dissimilar joining of reduced activation ferritic–martensitic steel to AISI 316LN austenitic stainless steel is carried out by brazing in inert atmosphere at three different temperatures, i.e. 980, 1020 and 1040°C using AWS BNi-2 powder. The braze joints are characterised by scanning electron microscopy, X-ray diffrac…
Abstract Epitaxial growth of graphene on SiC is a scalable procedure that does not require any further transfer step, making this an ideal platform for graphene nanostructure fabrication. Focused ion beam (FIB) is a very promising tool for exploring the reduction of the lateral dimension of graphene on SiC to the nano…
Abstract The preparation and characterization of a new family of four polyoxothiometalate (POTM) clusters are reported, with varying size and complexity, based upon the dimeric [Mo 2 O 2 S 2 (H 2 O) 6 ] 2+ cation with the general formula (NMe 4 ) a K b [(Mo 2 O 2 S 2 ) c (TeO 4 ) d (C 4 O 4 ) e (OH) f ] where a , b ,…
The present study focused on the synthesis of spherical silver nanoparticles (Ag NPs) using Gundelia tournefortii L. aerial part extract. The plant extract could reduce silver ions into Ag NPs. To identify the compounds responsible for the reduction of silver ions, functional groups present in plant extract were inves…
Two cyanide-bridged compounds based on the Fe II cation and the anisotropic [Mo III (CN) 7 ] 4– anion, namely, {Fe 2 (H 2 O) 5 [Mo(CN) 7 ]·5H 2 O} n ( 1 ) and {[NH 2 (CH 3 ) 2 ] 2 Fe 5 (H 2 O) 10 [Mo(CN) 7 ] 3 ·8H 2 O} n ( 2 ), have been prepared. Single crystal X-ray analyses revealed that their structures exhibit di…
A family of tri‐β‐substituted porphyrins, MTPP(CH 3 ) 2 X (M = 2H, Co, Ni, Cu and Zn; X = NO 2 or CHO; TPP = tetraphenylporphyrin), was synthesized and characterized by various spectroscopic techniques. The single‐crystal X‐ray structures of NiTPP(CH 3 ) 2 CHO and H 2 TPP(CH 3 ) 2 NO 2 revealed ruffled and saddle conf…
Mycotic keratitis is mainly responsible for vision loss caused by various fungi. Sometimes, proper treatment of such infection is not possible due to unavailability of effective antifungal agents and development of resistance of such fungi to antimycotic drugs. Hence, it is necessary to search for potential antifungal…
Green synthesis of silver nanoparticles (AgNPs) is an interesting issue of the nanoscience and nanotechnology due to their unique properties. In the present study, Ginkgo biloba L. leaf extract was used to synthesise AgNPs. The effects of quantity of leaves, concentration of Ag nitrate (AgNO 3 ), reaction temperature,…
In this paper, PE100 pipes with the diameter of 200 mm and the thickness of 11.9 mm were used as material. The welded joints were obtained in different welding pressures with the optimal welding temperature of 220[Formula: see text]C. Reheating process on the welded joints with the temperature of 130[Formula: see text…
Abstract This article is concerned with the invisibility cloaking in electromagnetic wave scattering from a new perspective. We are especially interested in achieving the invisibility cloaking by completely regular and isotropic mediums. Our study is based on an interior transmission eigenvalue problem. We propose a c…
This study evaluated the feasibility of bioplastics production by various ratio of sorghum starch and cellulose from red seaweed Eucheuma spinossum, and the use of glycerol as plasticizer and sorghum stalks as filler. Solid-liquid matrix transition should be far over the operating temperature of gelatinization and ext…
Abstract Vanadium dioxide (VO 2 ), one of the most promising phase-change smart materials, has shown strong frequency tuning capabilities in MEMS resonators. In this paper, we demonstrate the potential use of VO 2 -based MEMS devices as second-order kilohertz (kHz) bandpass filters with tunable band selectivity and ad…
An expeditious synthetic protocol for the construction of glycodendrimers is illustrated using the newly discovered “onion peel” strategy. The onion peel approach and orthogonal coupling strategies were accomplished with rationally design sequential modifications of cyanuric acid. Carefully chosen building blocks and…
The Vickers hardness of various AlX (X = N, P, As) compound polymorphs were calculated with the bond resistance model. Thermodynamic properties, such as vibrational entropy, constant volume specific heat and Debye temperatures, were calculated using phonon dispersion relations and phonon density of states (DOS). The c…
In this paper, potassium sodium niobate (KNN) nanopowders were successfully obtained by sol–gel combustion method. According to thermogravimetric analysis (TGA) results, the produced xerogel was calcined at 500[Formula: see text]C, 600[Formula: see text]C, and 700[Formula: see text]C to obtain KNN powders. The structu…
In this work, we investigate the adsorption of carbon dioxide on rhodium (Rh) nanocrystals as well as its catalytic reaction with hydrogen, at the nanoscale, using field ion microscopy (FIM), video-field emission microscopy (FEM), and one-dimensional atom probe (1DAP). A FEM pattern-and-brightness analysis during the…
Various structural features, such as proton disorder or noncovalent interactions, determine the existence of switchable nonlinear optical properties under varying external conditions.
