Electrochemical CO2 reduction presents a sustainable route to the production of chemicals and fuels. Achieving narrow product distribution with heterogeneous Cu catalysts is challenging conventional material modifications offer limited control over selectivity. Here, we show that surface-immobilised molecular species can act as inhibitors for specific carbon products provide rational distributi...
A new metal organic framework containing high density of active Cu sites demonstrates 100% oxidative conversion of CO to CO(2).
We present theoretically-established values of the CO-to-H2 and C-to-H2 conversion factors that may be used to estimate the gas masses of external galaxies. We consider four distinct galaxy types, represented by M51, NGC6946, M82 and SMC N27. The physical parameters that best represent the conditions within the molecular clouds in each of the galaxy types are estimated using a χ analysis of sev...
The total oxidation of toluene at a wide temperature range (200–500 oC) over micro/mesoporous platinated catalysts has been investigated about activity, selectivity to CO2 and CO, catalyst's stability versus coke deposition and reaction kinetics. Kinetic of toluene oxidation was measured under various oxygen and toluene pressures and als...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
