We study a stationary wetting problem on rough and inhomogeneous solid surfaces. We derive a new formula for the apparent contact angle by an asymptotic two-scale homogenization method. The formula reduces to a modified Wenzel equation for geometrically rough surfaces and a modified Cassie equation for chemically inho…
In this study, kinetic examinations on boronized AISI 304 Stainless Steel samples were described. Samples were boronized in indirect heated fluidized bed furnace consists of Ekabor 1? boronizing agent at 1123, 1223 and 1323 K for 1,2 and 4 hours. Morphologically and typically examinations of borides formed on the surf…
A promising technique has been developed to encapsulate clove oil in ethyl cellulose (EC) microcapsules using an emulsion solvent evaporation method. The method consists of emulsifying the oil with variations of core (clove oil) loading (1.5, 3.0 and 4.5) ml into EC shell material crosslinked by epichlorohydrin (ECH).…
Abstract This manuscript describes a novel approach for the preparation of composites based on cellulose paper (CP) modified with polypyrrole (PPy) and bromophenol blue (BPB) (CP/PPy/BPB). Cellulose fibers are suitable for uniformly retaining the polymer in its doped form, once BPB can be used as a negatively charged…
Currently, nanotechnology makes an impact in all spheres of human life and creates increasing excitement especially in the field of biomedicine and bionanotechnology. The important symbiosis between nanotechnology and green chemistry is the use of bioactive chemicals for the synthesis of nanoparticles. The present res…
Engineering scale superlubricity was realized by the fingerprint-like carbon films, which offer exciting application opportunity in vehicles, turbines, and manufacturing equipment.
Facile formation of silk fibroin/gelatin-heparin hybrid hydrogels for affinity-based growth factor sequestration and release.
The influence of the annealing temperature on the solubility and nucleating efficiency of TMBH has been clarified.
Pr <sup>3+</sup> /Yb <sup>3+</sup> doped materials have been widely reported as quantum-cutting materials in recent times.
To explore the utility of Si negative electrodes (NEs), we fabricated a new hybrid capacitor system using a Li pre-doped Si (Li alloyed Si) NE, denoted Si-CAP [Li alloyed Si | activated carbon (AC)]. The Si-CAP cell exhibited a relatively high charge/discharge capacity and higher cell voltage than that of a reference…
Recent reports of successful synthesis of atomically thin boron films have raised great prospects of discovering novel electronic and transport properties in a new type of 2D materials. Here we show by first-principles calculations that monolayer and bilayer γ-B28 films are intrinsically metallic while the thicker fil…
The synthesis of highly stable silver colloids has been successfully achieved by using reducing/stabilizer amino-functionalized polymers without the aid of any other external agent. The polymer coated inorganic nanoparticles have been detailed characterized via scattering, imaging and UV-Vis spectroscopy. The combinat…
The atmospheric corrosion behavior of zinc in the presence of NaCl has been investigated using well-controlled laboratory exposures in 95% RH air at ten different temperatures in the range −4 to 22°C. Results show that a critical temperature (∼ −0.5°C) exists in zinc corrosion above which the rate of corrosion is cons…
A mesostructured tin phosphate (SnPi) material has been prepared in the presence of an amphiphilic block copolymer (F127), tin chloride (SnCl <sub>4</sub> ), and phosphoric acid (H <sub>3</sub> PO <sub>4</sub> ) in an ethanol–water mixed solvent medium.
Compacted graphite iron (CGI) is considered to be one of the most promising materials for many automotive applications and has adopted by some automotive companies. Comparing to widely used flake graphite iron (FGI), CGI has superior physical and mechanical properties. The main drawback of this material is known to be…
The ability to detect and monitor toxic and greenhouse gases is highly important, however to achieve this at room temperature and allow for remote sensing applications is a significant challenge.
Mefenamic acid (MFA) and Nicotinamide (NIC) cocrystal formation in co-milling treatment was investigated by x-ray powder diffractometry (XRPD). Two polymorphic form of Mefenamic acid (MFA form I and MFA form II) were used to form a cocrystal with nicotinamide. Co-milling treatment was carried out at room temperature i…
A novel sensor was developed for the detection of kojic acid by blocking the formation of fluorescent poly T-templated Cu NPs.
Red-orange Sm3+ doped in CaMgPO4Cl halophosphate phosphor excited at 405 nm was prepared by combustion synthesis. The structure and properties were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and photoluminescence (PL) technique. The photoluminescence properties were studied by taking…
