Materials providing broadband light antireflection have applications as highly transparent window coatings, military camouflage, and coatings for efficiently coupling light into solar cells and out of light-emitting diodes. In this work, densely packed silicon nanotextures with feature sizes smaller than 50 nm enhance…
The inability to visualize the true extent of cancers represents a significant challenge in many areas of oncology. The margins of most cancer types are not well demarcated because the cancer diffusely infiltrates the surrounding tissues. Furthermore, cancers may be multifocal and characterized by the presence of micr…
Responsive graphene oxide sheets form non-covalent networks with optimum rheological properties for 3D printing. These networks have shear thinning behavior and sufficiently high elastic shear modulus (G') to build self-supporting 3D structures by direct write assembly. Drying and thermal reduction leads to ultra-ligh…
Hexagonal boron nitride (h-BN) has attracted significant attention because of its superior properties as well as its potential as an ideal dielectric layer for graphene-based devices. The h-BN films obtained via chemical vapour deposition in earlier reports are always polycrystalline with small grains because of high…
An optical anisotropic nature of black phosphorus (BP) is revealed by angle-resolved polarized Raman spectroscopy (ARPRS), and for the first time, an all-optical method was realized to identify the crystal orientation of BP sheets, that is, the zigzag and armchair directions. We found that Raman intensities of Ag(1),…
First-principles calculations are performed to investigate the interaction of physisorbed small molecules, including CO, H 2, H 2 O, NH 3, NO, NO 2, and O 2, with phosphorene, and their energetics, charge transfer, and magnetic moment are evaluated on the basis of dispersion-corrected density functional theory. Our ca…
The first circularly polarized OLED (CP-OLED) based on a chiral lanthanide complex is developed. With a simple architecture, this proof-of-concept device attains the highest polarization reported so far and additionally presents the first example of a Ln-based OLED that can be turned into a CP-OLED, fully retaining th…
As a reliable and scalable precursor of graphene, graphene oxide (GO) is of great importance. However, the environmentally hazardous heavy metals and poisonous gases, explosion risk and long reaction times involved in the current synthesis methods of GO increase the production costs and hinder its real applications. H…
Pickering emulsions are surfactant-free dispersions of two immiscible fluids that are kinetically stabilized by colloidal particles. For ecological reasons, these systems have undergone a resurgence of interest to mitigate the use of synthetic surfactants and solvents. Moreover, the use of colloidal particles as stabi…
The effect of thermal cycling through an interval of B2-L1 0 martensitic transformation (MT) under action of external stress and tensile stress-assistant ageing on the two-way shape memory effect in [ 23]-oriented Co 40 Ni 33 Al 27 (at.%) single crystals are investigated. For the first time it is experimentally establ…
This article presents the results of investigation into changes in the stored energy during the process of plastic deformation. It has been shown that the value of stored energy increases with the degree of deformation and the higher this value the lower the deformation temperature. The stored energy decreases with in…
In the present investigation the Thermal conductivity in particulate filler filled (Pine wood dust) epoxy composites at different volume fractions (6.5%, 11.3%,26.8% and 35.9%) have been determined experimentally by using Forced Convection apparatus. The composites of pine wood dust particles of 150 micron size have b…
Amphiphobic surfaces are being promisingly applied in numerous fundamental and industrial applications. A transparent amphiphobic coating was fabricated by combining fluoroalkyl silane copolymer (PFAS) with SiO2 nanoparticles. Dodecafluoroheptylmethacrylate (DFMA) and γ-methacryloxypropyltrimethoxysilane (γ-MPS) were…
Functional optical metamaterials usually consist of absorbing, anisotropic, and often noncentrosymmetric structures of a size that is only a few times smaller than the wavelength of visible light. If the structures were substantially smaller, excitation of higher-order electromagnetic multipoles in them, including mag…
The bond-stretch isomers are characterized by a principal change in the bond-length with the rest of the molecule being unaltered. The electronic structure regulates the bond stretch isomerism phenomenon in which has been investigated with density functional theory, ab initio CASSCF, highly efficient n-electron valenc…

In this paper, we have demonstrated magnetic ordering of single cobalt layer added on graphene using relativistic density functional theory at the level of generalized gradient approximation. We have shown that the single Co layer added on graphene show ferromagnetic ordering with perpendicular alignment to the graphe…
Data are presented which confirm that the SnSe2-Bi2Se3 system has a eutectic phase diagram, with a eutectic at 67 mol % SnSe2, melting at 831 ± 5 K. The thermoelectric properties of the eutectic alloy in this system have been studied for the first time in the temperature range 300–600 K. The results demonstrate that t…
Single crystalline p-type CdTe:Sb nanobelts were fabricated using an Au-catalyzed chemical vapor deposition method. Low carrier concentration and low mobility even at high Sb incorporation manifest compensation in the system. From cross examination of temperature-dependent charge transport and photoluminescence measur…
Elastomers, usually, are reinforced with reinforcing filler in order to improve their mechanical properties like tensile strength and abrasion resistance. The efficiency of this reinforcement is correlated with different factors like filler structure, surface area, and polymer–filler interactions. This study presents…
