While notable advances have been reported in the performance and short-term stability of spin-coated 2TPT-SCs up to 12 cm2(ref.25), these devices were yet limited to laboratory-scale tandem solar cells. Xiao
A cork that protects the oxygen content between two usesThe invention includes a bottle cap with a balloon in a cut bottle and an air vent to allow the air inlet or outlet of the bottle.PATRICK BONNET
Which process moves oxygen from the lungs into the blood? What are the two types of cellular respiration? What two processes fuel the carbon cycle? What are some uses of oxygen? What is the process of anaerobic respiration? What substance combines with oxygen in cellular respiration?
1. 1. During exercise of the squid Illex illecebrosus swimming up to 3 body lengths/sec, resting values at 15°C for both oxygen uptake (11.3 mM O 2/kg per hr) and ammonium excretion (1.4 mM NH 4/kg per hr) increased about five-fold; both parameters were always correlated with ...
Hydrogen peroxide (H2O2) is an efficient oxidant with multiple uses ranging from chemical synthesis to wastewater treatment. The in-situ H2O2 production via a two-electron oxygen reduction reaction (ORR) will bring H2O2 beyond its current applications. The development of carbon materials offers the ...

The oxygen evolution reaction has been envisaged on a two-dimensional graphyne (GY) nanosheet based on density functional theory framework. Local electronic/chemical environment on GY surface is significantly influenced and can be controlled by doping foreign atoms with different formats, which will ...
