Biomimetic Solution Against Dewetting in High Hydrophobic Nanopore

04-May-2016 | fabien picaud; guillaume paris; Tijani Gharbi; sebastien balme; Mathilde Lepoitevin; Vidhyadevi Tangaraj; Mikhael Be ..., Soft Matter, 2016

A water molecule is the foundation of life and symbolizes the primary compound in every life system. While many of its properties are understood in bulk solvent, its behavior in small hydrophobic nanopore still raised fundamental questions. For instance, wetting/dewetting transition in ...

Mechanism of Initial Step of Germano-silicate Formation in Solution: a First-principles Molecular Dynamics Study

04-May-2016 | Thuat T Trinh; Xavier Rozanska; Francoise DELBECQ; Alain Tuel; Philippe Sautet, Physical Chemistry Chemical Physics, 2016

The condensation reactions between Ge(OH)4 and Si(OH)4 units in solution is studied to understand the mechanism and stable species during the initial steps of the formation process of Ge containing zeolites in basic conditions. The free energy of formation of (OH)3Ge-O-Ge-(OH)2O-, ...

The anticonvulsant sulfamide JNJ-26990990 and its S,S-dioxide analog strongly inhibit carbonic anhydrases: solution and X-ray crystallographic studies

04-May-2016 | Anna Di Fiore; Giuseppina De Simone; Vincenzo Alterio; Vincenzo Riccio; Jean-Yves Winum; Fabrizio Carta; Claudiu Supuran, Organic & Biomolecular Chemistry, 2016

JNJ-26990990 ((benzo[b]thien-3-yl)methyl)sulfamide, a sulfamide derivative structurally related to the antiepileptic drug zonisamide, was reported to be devoid of carbonic anhydrase (CA, EC 4.2.1.1) inhibitory properties. Here we report that JNJ-26990990 and its S,S-dioxide analog significantly ...

Phototriggered release of amine from a cucurbituril macrocycle

04-May-2016 | J. Vázquez; M. A. Romero; R. N. Dsouza; U. Pischel, Chemical Communication, 2016

A method for the phototriggered release of a biogenic amine from the host–guest complex with the cucurbit[7]uril macrocycle in aqueous solution was devised. The approach exploits a photoinduced pH jump from 8 to 5, combined with the pH-dependent switching of the competitive capacity of a guest ...

Dominant Factors Limiting Optical Gain in Layered Two-Dimensional Halide Perovskites Thin Films

04-May-2016 | Wee Kiang Chong; Krishnamurthy Thirumal; David Giovanni; Teck Wee Goh; Xuefeng Liu; Nripan Mathews; Subodh Gautam Mh ..., Physical Chemistry Chemical Physics, 2016

Semiconductors are the ubiquitous gain media for coherent light sources. Solution-processed three-dimensional (3D) halide perovskites (e.g., CH3NH3PbI3) with their outstanding room temperature optical gain properties is the latest member of this family. Their two-dimensional (2D) layered ...

The effects of chondroitin sulfate and serum albumin on the fibrillation of human islet amyloid polypeptide at phospholipid membranes

04-May-2016 | Yang Li; Li Wang; Tong Lu; Ying Wei; Fei Li, Physical Chemistry Chemical Physics, 2016

Glycosaminoglycans and serum albumin are important cellular components that regulate the fibril formation of proteins. Whereas the effects of cellular components on the fibrillation of amyloid proteins in bulk solution are widely studied, less attention has been paid to the effects of cellular ...

Highly stable, luminescent core-shell type methylammonium-octylammonium lead bromide layered perovskite nanoparticles

04-May-2016 | Saikat Bhaumik; Sjoerd Veldhuis; Yan Fong Ng; Mingjie Li; Subas Kumar Muduli; Tze Chien Sum; Bahulayan Damodaran; Su ..., Chemical Communication, 2016

A new protocol for the synthesis of highly stable (over 2 months in ambient) solution-processed core-shell type structure of mixed methylammonium-octylammonium lead bromide perovskite nanoparticles (5-12 nm), with spherical shape, color tunability in the blue to green spectral region (438-521 nm) ...

Catalyst-Free Aldol Reaction in a Water Medium

04-May-2016 | Yao, Weirong; Cui, Yanli; Wang, Peipei; Mao, Yangyi, Letters in Organic Chemistry, 2016

Abstract: Background: With growing interest in developing environmentally friendly reactions and atom-economic processes in recent years, the utilization of water as a solvent has attracted a great deal of attention. This is not only for its low-cost, safe and environmentally benign nature, ...

New (green) methodology for efficient hydrazine cleavage

04-May-2016 | Lenka Kubovicova; Kristýna Bürglová; Jan Hlavac, Organic & Biomolecular Chemistry, 2016

An efficient method for removal of hydrazine group from (hetero)aromatic substrates has been developed. It can be realized both on solid support and in solution by synthesis employing low concentrated solution of trimethylsilanolate in tetrahydrofuran or N,N-dimethylformamide. For water-soluble ...

A New Insight into the Isotropic - Nematic Phase Transition in Lyotropic Solutions of Semiflexible Polymers: Density-Functional Theory Tested by Molecular Dynamics

04-May-2016 | Sergei Egorov; Andrey Ivanov Milchev; Peter Virnau; Kurt Binder, Soft Matter, 2016

Semiflexible polymers in solution are studied for a wide range of both contour length $L$ and persistence length $\ell_p$ as function of monomer concentration under good solvent conditions. Both density-functional theory (DFT) and Molecular Dynamics (MD) simulation methods are used, and very good ...
