There has been a revolution in nanotechnology and nanomedicine. Since 1980, there has been a remarkable increase in approved nano-based pharmaceutical products. These novel nano-based systems can either be therapeutic agents themselves, or else act as vehicles to carry different active pharmaceutical agents into speci…
Abstract As the world is marching into the era of the internet of things (IoTs) and artificial intelligence, the most vital development for hardware is a multifunctional array of sensing systems, which forms the foundation of the fourth industrial revolution toward an intelligent world. Given the need for mobility of…
Nano Cellulose is commonly produced by the top-down enzymatic, mechanical and/or chemical treatments. In contrast, Bacterial Nano Cellulose (BNC) can be obtained by a bottom-up approach, where is biosynthesized from glucose using the direct action of specific bacterial strains. BNC impart attractive combinations of bi…
RbBr nanocubes were transformed from solid to hollow nanostructure under e-beam irradiation while maintaining the size, exterior shape, and crystalline structure. The process of the morphological evolution was studied by in situ TEM characterization at atomic resolution. The transformation was attributed to combinatio…
in the ZnO membrane transferred onto a flexible polyethylene naphthalate substrate. Theoretical simulations reveal that it is a synergetic effect of the increased quantum efficiency via Purcell effect and the improved optical gain due to vertical directional waveguiding of the membrane, which functions as a Fabry-Pero…

Bismuth vanadate (BiVO 4 ) is an important semiconductor with wide applications, but in-depth understanding of its fundamental dynamic behaviors is still lacking. To address this issue, the comprehensive analysis of structure, internal friction (IF), modulus, dielectric, and impedance spectra was employed to unambiguo…
Two series of zinc tetraarylporphyrins containing four [Formula: see text],[Formula: see text]′-pyrrole fused butano or benzo groups were synthesized and characterized as to their electrochemical and spectroelectrochemical properties in nonaqueous media. The examined compounds are represented as butano(Ar) 4 PorZn and…
Acrylonitrile butadiene styrene rubber (NBR) has been widely applied in the automotive industry. However, unfilled NBR has poor properties. The purpose of this publication was to study the effects of carbon black (CB) variations on the thermal degradation and swelling resistance of NBR blends. The CB used in this stud…
surfaces. The etching porcess increases the surface roughness, therefore, the gradient of refractive index between air and silicon substrate is reduced. As a result, the Fresnel reflection is supressed. Our results demonstrate an efficient way of anti-reflective coating for solar cells.
Abstract Cyclic d / l peptides (CPs) assemble spontaneously via backbone H‐bonding to form extended nanostructures. These modular materials have great potential as versatile bionanomaterials. However, the useful development of CP nanomaterials requires practical methods to direct and control their assembly. In this wo…
Recovered carbon black (rCB), a very economical and abundance source of material, is transformed into dazzling multicolour fluorescence and visual display for the first time by way of a scanning focused laser treatment. This laser-initiated process is both straightforward and versatile, catering to both micro- and mac…
Silicone dioxide (SiO2) was extracted from baggase charcoal obtained from sugar factory. The charcoal was firstly dried at 105 °C for 2 hours followed by ashing at 800 °C and 900 °C. Treated baggase was then washed with 3% HCl under stirring at 240 rpm at 200 °C for 2 hours. Subsequently, to neutralise the pH, the aci…
Based on experimental studies of acoustic wave velocities in TlInSe2 crystals, all components of their elastic stiffness and compliance tensors are determined. TlInSe2 has three acoustic axes parallel to the principal crystallographic directions. The lowest velocities of acoustic eigenwaves are used to estimate the ac…
To investigate dependence of strain rate of tensile test for iron-based superalloy SUH660 (A286), tensile tests were conducted for the specimens in 70 MPa hydrogen gas and air at 150°C. Nominal stress-nominal strain curve of each strain rate in 70 MPa hydrogen gas showed same behavior to maximum load via yield point i…
Nanosilica (nS) are synthesized using the sol-gel method, with tetraethylorthosilicate (TEOS) as precursors, ammonia (NH 3 ) as base catalysts, water as hydrolysis and ethanol as solvents. Polyvinyl alcohol is added to the sol solution, serving as a capping agent. The purpose of this research is to know functional gro…
We study electrohydrodynamic convection (EHC) patterns in twisted nematic liquid crystal (TNCL) cells with an initial homeotropic alignment. In addition, we demonstrate switching characteristics due to the transition between the 90\ifmmode^\circ\else\textdegree\fi{} and $\ensuremath{-}{90}^{\ensuremath{\circ}}$ twiste…
Poly(ethylene) glycol (PEG)/ZrSiO 4 composites have been prepared and their thermomechanical propertis have been characterized using a dynamic mechanical analyzer (DMA). PEG 4000 was used as the matrix and a ZrSiO 4 powder, extracted from puya sand Kereng Pangi, Central Kalimantan, was used as the filler. ZrSiO 4 weig…
The aim of this study is to investigate the production conditions of silver nanoparticles (NPs) in the presence of AgNO3 with the fungal cytoplasmic fluid (FCF) of white rot fungus Coriolus versicolor. In this study, parameters such as pH, AgNO3 concentration and FCF ratio of C. versicolor were optimized. C. versicolo…
