In this study, we utilized a mandrel rotating collector consisting of two parallel, electrically conductive pieces of tape to fabricate aligned electrospun polycaprolactone/gelatin (PG) and carbon nanotube/polycaprolactone/gelatin (PGC) nanofibrous matrices. Furthermore, we examined the biological performance of the P…
The optimum bleaching parameters (clay dose and bleaching time) for palm kernel oil were determined using alkaline activated clay locally sourced in Nigerian. Activation was carried out using NaOH and KOH. The raw and activated clay samples were characterized using XRD and XRF. Bleached oil was analyzed for % colour r…
A theoretical approach coupling dynamic self-consistent field (SCF) theory for inhomogeneous polymeric fluids and variable cell shape (VCS) method for automatically adjusting cell shape and size is developed to investigate ordered microstructures and the ordering mechanisms of block copolymer melts. Using this simulat…
A new approach to dynamical determination of the active zone in the framework of the hybrid model (quantum mechanics/ molecular mechanics) is developed in this work. The proposed approach is based on using of the original method for calculation of the local stress on the atoms of structure, experiencing different exte…
microcapsules by cross-linking of the stabilizing particles of an inverse Pickering emulsion droplet at the interface. This was achieved by the ring-opening aminolysis reaction of the maleic anhydride residue of poly(St-co-MAh) with amine-functionalized silica particles that stabilized the Pickering emulsion. The cros…
Supported Pd/fiber glass, Pd/γ-Al 2 O 3 /fiber glass, Pd/γ-Al 2 O 3 catalysts were prepared by Surface Self-propagating Thermal Synthesis (SSTS) and tested in selective hydrogenation of acetylene to ethylene in the presence of CO. Temperature change in local liquid-phase surrounding of Pd atoms was monitored by XAFS i…
Carbon nanocapule (CNC)@MnO 2 core-shell particles are prepared with a reaction of KMnO 4 with CNC at 90°C. Birnessite-type MnO 2 nanoflakes are grown on CNC seeds, resulting in CNC@MnO 2 particles with a petal-like structure. The electrochemical characteristics of the prepared materials show that the highest specific…
The intense significance of biological molecules in our everyday lives has prompted the research into the analysis, identification and quantification of these molecules. Recently, surface-enhanced Raman scattering (SERS) study is identified as one of the effective techniques to detect and quantify such bio-molecules,…
Young's and shear moduli of carbon nanoscroll obtained through molecular structural mechanics considering various geometrical parameters.
Biodegradable copolyesteramide was synthesized from L-lactic acid oligomers and polyamide monomers to improve the properties of poly(lactic acid). The oligomer was synthesized from L-lactic acid using direct polycondensation process at 170 oC, 30 torr for 7 h. p-Toluenesulfonic acid used as a catalyst. From 1H NMR ana…
Highly crystalline Y2O3:Eu3+ yolk–shell phosphor powders with enhanced photoluminescence intensity are successfully prepared by spray pyrolysis. The Y2O3:Eu3+ yolk–shell powder is formed directly from each droplet containing yttrium and europium salts and sucrose inside a hot-wall reactor that is maintained at 900 °C.…
Organic nonlinear optical material of 4-bromo-4’-methyl benzylidene aniline (BMBA) was synthesized and single crystal of BMBA was grown by solvent evaporation method at room temperature using ethanol as solvent. The crystalline nature of the grown crystals was confirmed using powder X-ray diffraction studies. The crys…
A system for measuring Seebeck coefficient was constructed and applied to Bi 2 Te 3x Se x (x = 0.150.6) samples without harmful dopants, prepared by mechanical alloying (MA) followed by hot pressing (HP). The constructed thermal contact method system, using single and multiple T values, gave Seebeck coefficients of a…
To investigate how the structures and magnetic properties of azido–copper( ii ) chain compounds are influenced by substituents on the phenylacetic acid coligands, three new azido-bridged Cu( ii ) compounds have been successfully obtained, and structurally and magnetically characterized.
We demonstrate a sophisticated and unique method of Au deposition exclusively inside mesoporous silica, in clear contrast to conventional methods requiring surface modification with organic functional groups interacting with Au.
The effects of the surface roughness of a silicon dioxide substrate on the mechanical properties and Raman scattering of graphene prepared by chemical vapor deposition were investigated.
The role of Bi2O3addition on the structural and magnetic properties of NiCuZn-Tb ferrites with composition Ni0.5Cu0.25Zn0.25Tb0.1Fe1.9O4+xBi2O3has been investigated, where values of x (in wt %) are 0, 1, 2 and 3. Samples were prepared by the sol-gel auto combustion synthesis. The crystallographic, structural and magne…
Edge functionalized graphite were prepared by Friedel–Crafts acylation with l -phenylalanine. The functionalized nanoplatelates are highly dispersible in polar solvents and shows enhanced electron transfer capability compared to pristine graphite.

For the first time, metastable wurtzite CuInS2 nanocrystals and films were successfully synthesized from aqueous solution under atmospheric conditions. The CuInS2 nanocrystals were prepared by stirring and reflux of a metal salt and sodium sulfide in aqueous solution containing thioglycolic acid as a stabilizer. The g…
