New nanoporous carbons with extremely high mesopore volumes and surface areas have been produced using silica nanoparticles as templates. The polymerization of resorcinol and formaldehyde (RF) in the presence of silica sol particles generated RF gel-silica nanocomposites. Carbonization followed by HF etching of silica templates generated nanoporous carbons with pore sizes predominantly in the range of 10−100 nm. These carbons exhibited very high pore volumes of >4 cm3/g and high surface areas of

A simple preparative method for mesoporous carbons with high pore volumes using surfactant stabilized silica particles as templates is reported.

Nanocrystalline TiO2 photocatalysts: We have synthesized highly crystalline TiO2 nanocrystals by the controlled sol–gel reaction of titanium tetraisopropoxide in aqueous solution at room temperature. Anatase nanorods, spherical anatase nanocrystals, and rutile nanorods were synthesized (see HRTEM image of the latter). The anatase nanorods show much better photocatalytic activities for Eosin Y, phenol photooxidation, and E. coli inactivation than Degussa P-25. Supporting information for this arti

The aim of this paper is to critically assess the extent to which the concept of second modernity and reflexive modernization proposed by Beck and Grande is relevant to East Asia. Concepts such as driving forces, human agency, objective-structural versus cultural-discursive dimensions, radicalizing versus deficiencies aspects of modernity, push versus pull factors are used to clarify the basic conditions of this historical transformation. Utilizing these conceptual schemes, this paper has advanc

Although the incidence of bleeding complications during extracorporeal membrane oxygenator (ECMO) support has decreased in various trials, bleeding is still the most fatal complication. We investigated the ideal dosage and efficacy of nafamostat mesilate for use with ECMO in patients with acute cardiac or respiratory failure. We assessed 73 consecutive patients who received ECMO due to acute cardiac or respiratory failure between January 2006 and December 2009. To evaluate the efficacy of nafamo

Discrete single-walled carbon nanotubes (SWCNTs) with uniform diameters of 3.0 and 1.8 nm were synthesized using binary arrays that were composed of monodisperse zirconia nanoparticles with a particle size of 2.0 nm and monodisperse iron oxide nanoparticles with particle sizes of 3.3 and 1.8 nm as catalysts for chemical vapor deposition of methane. The agglomeration of iron oxide nanoparticles during the SWCNT growth was prevented by embedding the active catalyst nanoparticles in an inactive zir

We conclude that ECMO insertion within 60 min of the arrival of patients with AMI and CA at the ED appears to be a good option for maintaining myocardial and systemic perfusion, thereby increasing the survival rate of these patients.
