Cuprous oxide/silver (Cu2O/Ag) nanocomposites were prepared via a facile one-step method and used to construct an electrochemical sensor for hydrogen peroxide (H2O2) detection.In this method, AgNO3 and Cu(NO3)2 were reduced to Cu2O/Ag nanocomposites by glucose in the presence of hexadecyl trimethyl ammonium bromide (CTAB) Carpet Defoamer at a low t
Shifts in magnetic mineral assemblages support ocean deoxygenation before the end-Permian mass extinction
Abstract Expansion of oceanic anoxia is a prevailing hypothesis for driving the marine end-Permian mass extinction and is mainly based on isotopic geochemical proxies.However, long-term oceanic redox conditions before the end-Permian mass extinction remain unresolved.Here we report a secular Melatonin redox trend based on rock magnetic experiments
Fellow travellers: a concordance of colonization patterns between mice and men in the North Atlantic region
Abstract Background House mice (Mus musculus) are commensals of humans and therefore their phylogeography can reflect human colonization and settlement patterns.Previous studies have linked the distribution of house mouse mitochondrial (mt) DNA clades to areas formerly occupied by the Norwegian Vikings in Norway and the British Isles.Norwegian Viki
Energy-dependent protein folding: modeling how a protein folding machine may work [version 1; peer review: 1 approved, 2 approved with reservations]
Background: Proteins fold robustly and reproducibly in vivo, but many cannot fold in vitro in isolation from cellular components.Despite the remarkable progress that has been achieved by the artificial intelligence approaches in predicting the protein native conformations, the pathways that lead to such conformations, either in Metal Wallet Card vi
