(
Wiley-Blackwell
, 2019 , Article)
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 ...

Upgrading Calcium Bentonite to Sodium Bentonite Using Seawater and Soda Ash
(
American Chemical Society
, 2019 , Article)
In this paper, a new method is introduced to produce sodium bentonite by treating calcium bentonite using seawater to eliminate the use of freshwater and reduces the amount of soda ash required for the treatment, which ...
