Arylsilane Cross-Coupling Agent The cross-coupling reaction is a highly useful methodology for the formation of carbon-carbon bonds. It involves two reagents, with one typically being a suitable organometallic reagent - the nucleophile - and the other a suitable organic substrate, normally an unsaturated halide, tosylate or similar - the electrophile.
Halloysite nanotubes (HNTs) are naturally-occurring alu-minosilies [7,8] chemically similar to kaolin [7,9-13], and are mined from deposits in China, the United States and Brazil, among others [10]. They are inexpensive compared to carbon nanotubes [10,12

A coupling agent for the mechanical improvement of a synthetic composite can, for example, in some cases as well be used as an adhesion promoter between a coating and the substrate. Irrespective of the definition, these additives can positively influence the adhesion of coatings on aged paintwork, the tolerance towards of surface impurities, and the resistance to moisture and corrosion.

Here, we engineered M13 bacteriophage to stabilize single-walled carbon nanotubes for selective, targeted imaging of ovarian tumors. These nanoprobes fluoresce at longer near-infrared wavelengths than current probes, thereby improving noninvasive detection of small, deep tumors and guidance for surgical removal of submillimeter tumors.
Single-wall carbon nanotubes (SWNTs) are highly conjugated carbon tubes that are a few nanometers in diameter and can be up to millimeters in length. 1 1.M. S. Dresselhaus, G. Dresselhaus, and P. C.

To alleviate the kinetic barriers associated with ORR (oxygen reduction reaction) and OER (oxygen evolution reaction) in electrochemical systems, efficient nonprecious electroalysts are urgently required. Here we report a facile soft-template mediated approach for fabriion of nanostructured cobalt–iron double sulfides that are covalently entrapped in nitrogen-doped mesoporous graphitic
2008/6/5· Using carbon nanotubes, MIT chemical engineers have built the most sensitive electronic detector yet for sensing deadly gases such as the nerve agent sarin. The technology, which could also detect mustard gas, ammonia and VX nerve agents, has potential to be used as a low-cost, low-energy device that could be carried in a pocket or deployed inside a building to monitor hazardous chemicals.
Aflatoxins are the secondary metabolites of Aspergillus flavus and Aspergillus parasiticus and are highly toxic and carcinogenic, teratogenic and mutagenic. Ingestion of crops and food contaminated by aflatoxins causes extremely serious harm to human and animal health. Therefore, there is an urgent need for a selective, sensitive and simple method for the determination of aflatoxins. Due to
