Singlet oxygen-promoted one-pot synthesis of highly ordered mesoporous silica materials via the radical route

Abstract

The emergence of the free radical route has eliminated the need for a strong acid to catalyze the hydrolysis and condensation of silica species during the hydrothermal synthesis of highly...

Experimental investigation of mechanical properties of Kevlar fiber composite sandwich panel with truss core reinforced bynano‐SiO2

“…The face sheets and the core components of the sandwich panels used in this research are produced with resin epoxy/Kevlar fiber laminates. The laminated plates are fabricated from 14 layers of woven Kevlar (aramid) fiber (K29/1.44 g/cm 3 purchased from Toray company, Japan [29] ) with a thickness of 0.18 mm and resin epoxy (EPL1012; provided by Shell Chemicals company, [30,31] hexion specialty chemicals; Nanhai, China [32] ). The tensile modulus and tensile strength of the Kevlar fiber is 112 and 3 GPa, respectively.…”

Antioxidant Thermogelling Formulation for Burn Wound Healing

“…Hydrogels are three-dimensional macromolecular networks composed of hydrophilic polymers. [26][27][28] Due to the presence of hydrophilic functional groups in the polymer backbone, they possess the ability to retain water. [2][3][4][5][6][7][8][9]39] On the one hand, the damp hydrogels keep the wound moist and isolates the wound from the outside environment, [40] and on the other hand, the high water absorption ensures that the hydrogel can absorb wound exudate until the dissolution equilibrium.…”

Minutely dispersed ruthenium in tremella-like N-doped carbon for enhanced visible-light-driven photocatalytic hydrogen production by CdS quantum dots

“…[22][23][24] In addition, the decoration of noble metals with QDs usually leads to excessive loading and the low utilization of noble metals. To overcome these disadvantages, a suitable porous support should be employed, 25 so that the ratio of noble metal to QDs can be varied over a wide range on the surface of the support.…”
