Large Anomalous and Topological Hall Effect and Nernst Effect in a Dirac Kagome Magnet Fe3Ge
Advanced Functional Materials, EarlyView.Fe3Ge, a Kagome‐lattice magnet, exhibits remarkable anomalous Hall and Nernst effects, with transverse thermoelectric conductivity surpassing or comaprable to some well‐known ferromagnets. First‐principles calculations attribute these to Berry curvature from massive Dirac gaps. Additionally, topological Hall and Nernst signals emerge from field‐induced

Evidence of hydrological control of Sr behavior in stream water (Strengbach catchment, Vosges mountains, France) [PDF]
, 2002 Strontium and particularly 87Sr/86Sr ratios in stream water have often been used to calculate weathering rates in catchments. Nevertheless, in the literature, discharge variation effects on the geochemical behavior of Sr are often omitted or considered ...

Stable carbon isotope ratio of submerged freshwater macrophytes1,1 [PDF]
Limnology and Oceanography, 1982 The stable carbon isotope ratio of submerged freshwater macrophytes is substantially higher than that of terrestrial C3 plants. This difference is consistent with the high diffusion resistance to inorganic carbon flux in the aquatic medium but also appears to be a function of the more negative carbon ratio of the dissolved inorganic carbon available to

Advanced Functional Materials, EarlyView.A sequence‐encoded supramolecular construct containing two accessible toeholds is developed herein for enabling multiple editing operations. By introducing specific input strands, it is possible to selectively erase or rewrite digital content through parallel or series toehold‐mediated strand displacement (PTMSD or STMSD).

Stable Isotope Ratios in Hair and Teeth Reflect Biologic Rhythms
PLoS ONE, 2007 Biologic rhythms give insight into normal physiology and disease. They can be used as biomarkers for neuronal degenerations. We present a diverse data set to show that hair and teeth contain an extended record of biologic rhythms, and that analysis of these tissues could yield signals of neurodegenerations.

Chemical stability of levoglucosan: An isotopic perspective
Geophysical Research Letters, 2016 The chemical stability of levoglucosan was studied by exploring its isotopic fractionation during the oxidation by hydroxyl radicals. Aqueous solutions as well as mixed (NH4)2SO4‐levoglucosan particles were exposed to OH.
