p‐Cu(OH)2/n‐SrTiO3 Heterojunction for Efficient Photocatalytic Hydrogen Production

open access: yesAdvanced Sustainable Systems, EarlyView.
Improving the efficiency of photocatalysts in the hydrogen evolution reaction relies on developing cost‐effective co‐catalysts. This study focuses on p‐Cu(OH)2/n‐SrTiO3 heterojunctions for efficient hydrogen production. 1 wt.% Cu‐based co‐catalyst significantly enhances performance, achieving ≈3.5 times higher hydrogen production compared to pristine ...

Multi‐Omics and ‐Organ Insights into Energy Metabolic Adaptations in Early Sepsis Onset

open access: yesAdvanced Science, EarlyView.
This study shows that patients at risk of sepsis have a distinct metabolite and lipid signature, including serine and aminoadipic acid, in their serum before clinical diagnosis. A mouse model of sepsis with a compatible serum signature reveals underlying metabolic changes, including mitochondrial adaptation, altered serine‐dependent purine metabolism ...

Heme/NADH Mimics Co‐Decorated Allosteric Capsules for Regulating Oxygen Activation and Upregulating Intracellular Methionine Depletion

open access: yesAdvanced Science, EarlyView.
Through modifying the switchable µ‐oxo bridged FeIII‐porphyrins moiety and NADH mimics into a metal‐organic capsule, multiple responsive manners for O2 activation, chemical oxygenation and metabolic transformation have been demonstrated for upregulating intracellular methionine depletion and accumulation of methionine sulfoxide to achieve effective ...

Six mechanisms used on the SSM/1 radiometer [PDF]

open access: yes, 1985
Future USAF Block 5D Defense Meteorological Satellites will carry a scanning microwave radiometer sensor (SSM/1). SSM/1 senses the emission of microwave energy and returns to earth data used to determine weather conditions, such as rainfall rates, soil ...
