Reactive membrane, and a carbon layer on at least one is modified to yield a porous substrate, active sites were deposited on a porous substrate. And partially deoxygenated least, active site comprises a metal species that are chemically bonded to the carbon layer. Method for forming a reactive...
(e.g., RuO2, IrO2) has been widely reported, the sustainable large-scale commercial use of such catalysts is severely impeded by their scarcity, high cost, and electrochemical instability.2Great effort has therefore been devoted to the development of economically viable, highly efficient, and ...
Rh(I)/dppe-catalyzed cycloisomerizations of BCBs are intermolecular reactions, and the Rh catalyst tends to attack the external carbon via TS18. This is facilitated by the fact that the substituents on the highlighted carbon atom (black circle) in TS18 can easily assume a staggered conformation...
There are a variety of potential ways to do this, including buildingdirect-air-capture machines, deployingreactive mineralsthat can tie up the carbon dioxide, and convertingplants into bio-oiland then injecting it deep underground. The general promise is that these approaches...
Crisis management is as necessary as it is reactive. A proactive approach is needed to shape the company’s future and its contribution to society. While optimizing the allocation of resources works best under stable circumstances, disruption makes that impossible. It’s time to move away f...
Nanoscale science may provide fuel cell developers with some much sought after answers. For example, gold is usually an unreactive metal. However, when reduced to nanometer size, gold particles can be as effective a catalyst as platinum.
Samset1 Black carbon (BC), unlike most aerosol types, absorbs solar radiation. However, the quantification of its climate impact is uncertain and presently under debate. Recently, attention has been drawn both to a likely underestimation of global BC emissions in climate models, and an ...

A group of heterocyclic macrocycle organic compounds composed of four modified pyrrole subunits interconnected at their α-carbon atoms by methine bridges. Singlet oxygen The reactive oxygen species 1O2. Urocanic acid (UCA). A breakdown (deamination) product of histidine that is an important epidermal...
This anticipatory expression may confer an adaptive advantage, as stress caused by reactive oxygen species is the most critical stress to anaerobes such as SRMs. The ability of D. vulgaris to grow syntrophically with methanogens allows its distribution and evolution in environments that are depleted ...
