And lower non-radiative recombination loss of 0.168 eV is further achieved in PM1:BTP-eC9 organic solar cell (19.10% efficiency), giving great promise to future organic solar cell research.Similar content being viewed by others Mastering morphology of non-fullerene acceptors towards long-term ...
2p, the exothermic characteristic of the PAL membrane was consistent with that of pure PAN, which can be ascribed to the high PAN content in the composite membrane. The glass transition temperature (Tg) of pure PAN membrane was about 112.1 °C, whereas the bare PLLA powders exhibited a ...
Furthermore, even if we were to hold that the chemical vapor was "smoke" within the meaning of the policy, it was the result of the degreaser's malfunctioning. Because the operation of the degreaser is an "industrial operation," this incident is specifically excluded from coverage under the ...
The BET method is less suitable for the analysis of micropores, as N2 has a diameter slightly greater than that of the Ps atom (1.06 Ǻ), meaning the latter cannot penetrate closed pores. The two methods applied to medium-sized pores yielded identical results, as the free volume (ΔR)...
This is the term that chemists use to define all this family and even more. Etymologically the word polymer comes from Greek origins and is formed by two parts: poly- meaning many, and -meros meaning parts. Therefore, from the chemical point of view, everything that is composed of many ...
However, they observed that the temperature difference (ΔT) of the material during the stretching phase was higher than that in the recovery stage, meaning that undesired dissipative phenomena occurred. Coativy et al. examined the elastocaloric effect of thermoplastic polyurethane (TPU), noting ...
The meaning of Poincare theorem is important for high temperature plasma confinement. Considering the boundary surface of the magnetic confinement, the plasma will leak from the zero point of a magnetic field vector. To confine the hot plasma, the surface must be covered by non-zero magnetic ...
