Synthesis of Ordered Mesoporous Silica with Tunable Morphologies and Pore Sizes via a Nonpolar Solvent-Assisted Stöber Method
(
American Chemical Society
, 2016 , Article)
A facile nonpolar solvent-assisted Stöber method has been developed to synthesize ordered mesoporous silica materials with tunable pore size and diverse morphologies and mesostructures by using cetyltrimethylammonium bromide ...
CTGF Loaded Electrospun Dual Porous Core-Shell Membrane For Diabetic Wound Healing
(
Dove Medical Press Ltd.
, 2019 , Article)
Purpose: Impairment of wound healing is a major issue in type-2 diabetes that often causes chronic infections, eventually leading to limb and/or organ amputation. Connective tissue growth factor (CTGF) is a signaling ...

The effect of initial and final curing conditions of ordinary concrete cast in regions with harsh environmental conditions on the compressive strength and microstructure of concrete is investigated in this research. More ...
Carbonization conditions influence the emission characteristics and the stability against photobleaching of nitrogen doped carbon dots
(
Royal Society of Chemistry
, 2017 , Article)
Carbon Dots (CDs), fabricated by hydrothermal bottom-up synthesis, are complex materials, whose optical properties are influenced by multiple factors. The presence of domains of conjugated sp2 carbon, which are formed upon ...
Multilayer-MCTDH approach to the energy transfer dynamics in the LH2 antenna complex
(
Institute of Physics Publishing
, 2017 , Article)
The multilayer multiconfiguration time-dependent Hartree method is used to study the coupled exciton–vibrational dynamics in a high-dimensional nonameric model of the LH2 antenna complex of purple bacteria. The exciton–vibrational ...
