The measurement of carbon emissions on the customer side is a prerequisite for low-carbon dispatch and carbon trading, and the calculation of carbon emissions per kWh is a necessary condition for ...

Emissions of volatile organic compounds (VOCs) from the chemical industry are intricate. Large uncertainties exist in the estimation of VOC emission intensities. Measurement- and calculation-based ...

The suppression of spontaneous emission introduced by a two-dimensional honeycomb-rod photonic bandgap structure is evaluated using the plane-wave expansion theory. An analysis of the out-of-plane ...

The radioligand [11C] N-methylspiprone (NMSP) has been used to assess relative and absolute D2 dopamine receptor densities in the living human brain with positron emission tomography (PET). In those ...

We have evaluated a novel in vitro cell-based human blood−brain barrier (BBB) model that could predict in vivo human brain penetration for compounds with different BBB permeabilities using the ...
