A new variety in natural fibre and is first of its kind i.e. Palmyra Palm botanically called Borassus Flabellifer ‘petiole fibre’ is introduced in the present work. The main aim of the work is to extract the neat fibre and is characterized for its tensile and surface characteristics. The composites are fabricated by r…
Bismuth antimony (Bi 1−x Sb x ) is one of the most important materials systems for fundamental materials science, condensed matter physics, low temperature thermoelectrics, infrared applications, and beyond.
Microporous nickel phosphite [Ni11(HPO3)8(OH)6] nanocrystals were prepared using a hydrothermal method, and were successfully applied as a positive electrode in a flexible all solid-state asymmetric supercapacitor. Because of the specific micro/nanostructure, the flexible solid-state asymmetric supercapacitor can achi…
We describe the synthesis of charge-stabilised gold and silver nanoparticles by a modified Turkevich method and their interaction with a selection of cationic and anionic dyes. It was found that gold nanoparticles interact strongly with cationic dyes and in some cases enhanced absorption was observed by UV-visible spe…
Nickel ferrite (NiFe 2 O 4 ) is synthesized by using auto combustion method with citric acid as a chelating agent. The formation of single phase nickel ferrite was confirmed through powder X-ray diffraction. The vibrational analysis was confirmed through fourier transform infrared spectroscopic (FTIR) analysis. The co…
Stimulated emission depletion (STED) and structured illumination (SIM) are two commonly used techniques for super-resolution imaging. However, the performance of these two techniques has never been quantitatively compared side-by-side. Taking advantage of the non-photobleaching characteristic of NV centres in fluoresc…
Ce(3+) ions are introduced into the lattice of Y2Mo3O12 with a sol-gel method with the aim to reduce its hygroscopicity and pursue the interaction of crystal water molecules with the building block. It is found that Ce(3+) ions occupy the positions of Y(3+) in the lattice and have the function of expelling crystal wat…
Al2O3-covered SiC/epoxy composites were prepared using a simple sol–gel method. The results of FE-SEM, TGA, and XPS indicated that the surfaces of the SiC particles had a large, dense, and homogenous distribution of Al2O3. It was found that the introduction of Al2O3 on the SiC surface improved the interfacial adhesion…
A new copper–silver–thiostannate, [enH][Cu 2 AgSnS 4 ] ( 1 ), which features a quaternary two dimensional anionic [Cu 2 AgSnS 4 ] − layer, has been solvothermally synthesized.
Strategies often ignored could become very important for the preparation of high quality graphene and its functionalization.
Optical and photocatalytic properties of β-NaYF 4 :5% Tb 3+ phosphor crystals with multiform morphologies fabricated via a binary capping agent system.
In this communication we report for the first time the use of azobenzene modified glycoconjugates to establish optical control over bioactive ligands at a supramolecular β-cyclodextrin (β-CD) surface. Several studies were conducted to investigate the photoresponsive immobilization of proteins and bacteria on these sup…
The present study demonstrates that highly water-dispersed graphene nanoribbons dispersed by carboxyphenylated substituents and conjugated to aquated Gd(3+) ions can serve as a high-performance contrast agent (CA) for applications in T1- and T2-weighted magnetic resonance imaging (MRI) with relaxivity (r1,2) values ou…
We attached anti-human serum albumin (anti-HSA) affibody ligands on bacterial cellulose (BC) by EDC–NHS-mediated covalent conjugation and physical adsorption and demonstrate their application for tubular biofiltration of blood proteins.
Multiplexed surface enhanced Raman scattering (SERS) substrates, which enable chemically selective detection of two or more target analytes from a complex chemical mixture, are highly attractive for chemical detection in real-world settings. We introduce a new approach called plasmonic calligraphy that involves the fo…
Trimetallic nanocages possess inter-metallic synergies among elements and are able to generate significant SERS signal enhancement due to “hot spot” formation.
Composite films of polypropylene (PP) and modified calcium carbonate (CaCO 3 ) were prepared in a twin screw extruder with particle content varying from 0.5, 1.0, and 1.5 phr. The CaCO 3 surface was modified by palmitic acid (PA) at 1, 3, and 5%wt. The modified CaCO 3 surface was characterized by FTIR and XRD to indic…

In this study CsH 2 PO 4 /polyvinylidene fluoride (PVDF) composite electrolytes were prepared by a slurry casting method and their application in intermediate temperature fuel cells (ITFCs) was investigated. The composite electrolytes consisted of a physical dispersion of CsH 2 PO 4 particles in the PVDF polymer netwo…
The development of cerium-rich layers on anodized pure aluminum and AA7075 T6 aluminum alloy has been investigated using scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectroscopy. The surfaces of pure aluminum and AA7075 T6 were pre-treated by alkaline etching and HNO 3 desmut…
