5-Alkyl derivatives of benzotriazole (1–12 carbon atom long alkyl chain) were tested as inhibitors of pure iron corrosion in sulphuric or hydrochloric acid at 25°C and pure copper corrosion in acidic sulphate and saline solutions at 30°C. This series of compounds was more efficient in contrasting copper than iron corr…
The effect of flow on crystallization is commonly attributed to entropic reduction, which is caused by stretch and orientation of polymer chains but overlooks the role of flow on final-state free energy. With the aid of in situ synchrotron radiation wide-angle X-ray diffraction (WAXD) and a homemade constrained uniaxi…
This study examined the feasibility of using a sintered Ag/AgCl electrode as a combined reference (RE) and counter electrode (CE) for polarization measurements in thin film solutions. The combined electrode provided uniform current distribution without altering the thin film electrolyte composition. This approach avoi…

Scheme of pen processing resulting in “curtain” effect of Pd.
Coupling seed-mediated co-reduction with galvanic replacement for the first time provides a route to trimetallic (Ag-Au-Pd) nanostructures with hollow interiors. Moreover, manipulating the synthetic conditions can suppress galvanic replacement and facilitate formation of trimetallic core@shell (Ag@Au-Pd) nanostructure…
The effect of Pluronic block copolymers F127 and P123 on aqueous dispersions of graphene oxide (GO) was studied.
With the rapid growing of nanotechnology, the effects of nanomaterials released into the environment on plants have drawn more and more attention. Iron is an element essential for plant growth and development. Iron is involved in chlorophyll formation; iron deficiency will cause a plant disorder known as chlorosis. Ho…
FORMULATION AND CHARACTERIZATION OF EPIGALLOCATECHIN GALLATE NANOPARTICLES EGCG have variety of therapeutic advantages including HIV.

Best results were obtained when the alkoxy group on the thiophene ring was closer to the donor moiety.
We investigated the rotational dynamics of single microparticles during their internalization by macrophage cells. The microparticles used were triblock patchy particles that display two fluorescent patches on their two poles. The optical anisotropy made it possible to directly visualize and quantify the orientation a…
Thermoregulated POM-type ionic liquid gels show reversible phase transformation, increasing conductivities. And W-containing compounds have higher conductivity than the Mo-containing one, like the Dawson-type one compared with the Keggin-type one.
Multilayered particles are emerging as a powerful platform in pharmaceutics, especially for targeted, triggered and sustained drug delivery. These novel delivery systems exhibit advantages over single-layered particles, such as mitigating burst release of drugs. In this article, an overview of recent developments in t…
Supramolecular interactions between the terminal pyridyl groups and TCNQ radicals induce structural distortions in [Co(pyterpy) <sub>2</sub> ](TCNQ) <sub>2</sub> spin-crossover materials.
Whilst the corrosion protection of steel in aqueous chloride environments by the rare earth inhibitor lanthanum 4-hydroxycinnamate is well known, the influence of the structural variation of the organic component as well as the nature of the metal centre has not previously been addressed. Herein we show that praseodym…
A simple SERS immunosensor based on AuNRs assembly was developed for rapid detection of specific antigen in early diagnostics.
In conjunction with the constrained density functional theory, a valence-bond representation has been employed to model the migration of anionic polaron in bulk rutile TiO2. It was found that the charge delocalization of a self-trapped electron proceeded predominately along the c crystal axis of rutile, thus exhibitin…
Pearlman's catalyst, nominally Pd(OH)2/C, is widely used as for hydrogenation reactions and C-C coupling reactions. Contrary to the accepted view, we show that Pearlman's catalyst as prepared and after drying consists of carbon supported (mostly) nano-particulate hydrous palladium oxide capped with a monolayer of hydr…
Nanohybrids from waterborne polyurethane, poly(vinyl alcohol) and silver nanoparticles of ultrasmall sizes (5.1 ± 0.6 nm) are facilely obtained by directly one-step dual-spinneret electrospinning fabrication in water without additional chemicals.
Density functional theory with dispersion-correction (DFT-D) was employed to study the effects of vacancy and pressure on the structure and initial decomposition of crystalline 5-nitro-2,4-dihydro-3H-1,2,4-triazol-3-one (β-NTO), a high-energy insensitive explosive. A comparative analysis of the chemical behaviors of N…
