Abstract The novel hybrid catalyst Cu@IA‐SBA‐15 was synthesized by anchoring isatoic anhydride on amino‐functionalized SBA‐15. The synthesized process pursued by grafting of Cu(II) to catch desired product. 2D‐hexagonally ordered mesoporous of bidentate ligand characterized by X‐ray diffraction spectroscopy (XRD), N 2…
Fringescalesardinella or TambanSisik bones have been discovered can be utilized as sunscreen agent in cosmeceuticals. Its flesh is the main ingredient in keropoklekor or fish crackers in Malaysia and the bones contained very high hydroxyapatite (HAp), (Ca10(PO4)6(OH)2) compound which exhibit as UV light absorber. The…
The enhanced efficiency of the sodium dodecyl benzene sulphonate (SDBS) by the addition of trisodium phosphate and sodium benzoate on the corrosion inhibition of Mg-Al-Zn-Mn alloy in aqueous ethylene glycol solution (30%) containing chloride ions was studied by potentiodynamic polarization technique and electrochemica…
Up-conversion nanoparticles (UCNP) under near-infrared (NIR) light irradiation have been well investigated in the field of bio-imaging. However, the low up-conversion luminescence (UCL) intensity limits applications. Plasmonic modulation has been proposed as an effective tool to adjust the luminescence intensity and l…
Liposomes have been widely researched as drug delivery systems; however, the solid state form of drug inside the liposome, whether it is in solution or in a solid state, is often not studied. The solid state properties of the drug inside the liposomes are important, as they dictate the drug release behavior when the l…
A fast response (sub-milliseconds) and polarisation-independent blue-phase liquid crystal (BPLC) microlens array with periodical double layer electrodes using different dielectric layers is proposed. The bottom double layer electrodes are coated with transparent and different dielectric layers to generate linearly var…
This paper describes the preparation and characterization of CG/Co(OH)2 electrode obtained by electrodeposition of cobalt hydroxide on expanded carbon graphite electrode (CG) for potential application as energy storage devices. The CG electrodes used in this work were obtained from exhausted batteries. Firstly, the CG…
Abstract Liquid‐based thermochromics can be incorporated into an arbitrarily shaped container and provide a visual map of the temperature changes within its volume. However, photochemical degradation, narrow temperature range of operation, and the need for stringent encapsulation processes are challenges that can limi…
B and p38 pathways. Moreover, the ability of the nanocluster to protect neuronal cells to against microglial cytotoxins was also evaluated. Treating neuronal cells with the nanoclusters could protect them from cytotoxicity induced by supernatants of stimulated microglia cells through up-regulating of hemeoxygenase-1 (…
We report a strategy of using small cations to construct ionic liquid octahydrotriborate. The novel liquid Li(NH3)B3H8, prepared by a facile reaction of NH4B3H8 with LiH, froze below -33.4 °C and crystallized into a monoclinic unit cell with lattice parameters of a = 8.813(1) Å, b = 8.8626(1) Å, c = 8.2076(1) Å, and β…
Zero-field splitting (ZFS) of three high-spin Co(I) ( S = 1) clathrochelate complexes was determined by frequency-domain Fourier-transform THz-EPR (FD-FT THz-EPR). The following axial and rhombic ZFS values ( D and E, respectively) were determined: [N( n -Bu) 4 ]Co I (GmCl 2 ) 3 (BPh) 2 ( 1, D / hc = +16.43(1) cm –1,…
Medium-chain-length (MCL) polyhydroxyalkanoates (PHAs) of near homopolymeric composition are unnatural polymers, having almost identical repeating units throughout the polymer chain. These homopolymeric PHAs can be produced by β-oxidation defective bacterial hosts. Escherichia coli is an attractive workhorse for the p…
Colorimetric oxygen indicators can be applied for non-destructive testing in packaging; especially in modified atmosphere packaging (MAP). In this paper; titanium dioxide (TiO₂) nanotube; which is used as a semiconductor photocatalyst in oxygen indicators; was synthesized via a microwave-assisted hydrothermal method.…
Engineering heat transport at the nanoscale is important for thermal management in modern technology, but precisely how thermal resistance is affected by geometry and length scale has been a topic of debate. This study identifies a key parameter, the spatial frequency of a heating pattern, that governs thermal transpo…
19 F MRI requires biocompatible and non-toxic soluble contrast agents with high fluorine content and with suitable 19 F relaxation times. Probes based on a DOTP chelate with 12 magnetically equivalent fluorine atoms (DOTP-tfe) and a lanthanide(III) ion shortening the relaxation times were prepared and tested. Complexe…
Herein we present an in-depth study of precursor derived tungsten sulfides, with a focus on their micro- and local structures. We prepared a new tetrathiotungstate based precursor (N2H5)2WS4 and unveiled the details of its unique decomposition mechanism by a combination of in situ and ex situ analytical techniques. Up…
Changes in chemical state and structural transformations occurring in a series of MO x /CeO 2 (M = Cu, Ni and Fe) powder catalysts upon reaction with methane were investigated using in situ time-resolved X-ray diffraction (TR-XRD), ex situ X-ray absorption near edge structure (XANES)/extended X-ray absorption fine str…
