15/11/2021· sensors into something a lowcost chip (like the BIS0001) can sense. Lenses PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens

Splitting CO2 into CO and O2 by a single catalyst | PNAS


25/9/2012· The metal complex [(tpy)(Mebimpy)RuII(S)]2+ (tpy = 2,2′ : 6′,2′′terpyridine; Mebimpy = 3methyl1pyridylbenzimidazol2ylidene; S = solvent) is a robust, reactive electrocatalyst toward both water oxidation to oxygen and carbon dioxide reduction to carbon monoxide. Here we describe its use as a single electrocatalyst for CO2 splitting, CO2 → CO + 1/2 O2, in a twocompartment ...
