C 2012 American Chemical Society Graphene: The Game Changer? I t has only been eight years since the isolation of graphene 1 and over a year since the 2010 Nobel Prize in Physics was jointly awarded to Andre Geim and Konstantin Novoselov “for groundbreaking experiments regarding the two-dimensional material graphene.” Nevertheless, the number of graphene publications is still rapidly growing. T...

in this research at the first metoprolol drug and its fullerene derivative were optimized. natural bond orbital (nbo), nuclear indepndent chemical shift (nics) and finally ir calculations, for these compounds were carried out at the b3lyp/6-31g* quantum chemistry level. different parameters such as energy levels, the amount of chemical shift in different atoms, the amount of homo/lumo, chemical...

The review is stanch to supramolecular chemistry and theirvaious molecular assemblies. It mainly deals with applications of calix system, non-covalent interaction, fluorescence sensor, biosensor, nano biosensor. Recognition many moieties via suitable attached groups captivates the attention In addition it also highly selective specific towards bio molecules, anions, cations neutral substrate.

Analytical balance is at the heart of work by the famous French chemist Antoine Lavoisier, who relied on advanced instruments of the time that can still be discovered at the Arts et Métiers Museum in Paris. Analytical chemistry has been one of the fields of the Société Chimique de France (SCF) since its creation in 1857. The SCF was the owner of the journal Analusis , which merged with other na...

Synthesis of nano-scale fast ion conducting cubic Li Report Title A solution-based process was investigated for synthesizing cubic Li7La3Zr2O12 (LLZO), which is known to exhibit the unprecedented combination of fast ionic conductivity, and stability in air and against Li. Sol–gel chemistry was developed to prepare solid metal–oxide networks consisting of 10 nm cross-links that formed the cubic ...

A wide range of aa’vanced technology for existing and emerging products based on high temperature metal-ceramic composites used in aircrafts, cutting tools, lithium-ion based rechargeable batteries, superconductors, field emission based flat-panel displays, etc. employ micron to submicron sized ( 0.1 -10 microns) particulate precursors in their manufacturing process. Although there has been a s...

Metallic bone implants possess numerous problems limiting their long-term efficacy, such as poor prolonged osseointegration, stress shielding, and corrosion under in vivo environments. Such problems are compounded for bone cancer patients since numerous patients receive orthopedic implants after cancerous bone resection. Unfortunately, current orthopedic materials were not originally developed ...

One of the key steps in nanotechnology is our ability to engineer and fabricate low-dimensional nano-objects, such as quantum dots, nanowires, two-dimensional atomic layers or three-dimensional nano-porous systems. Here we report evidence of nanotunnel opening within the subsurface region of a wide band-gap semiconductor, silicon carbide. Such an effect is induced by selective hydrogen/deuteriu...
