Spatiotemporal variability of hydrogen and oxygen stable isotopes in the Han River Basin and the regional hydrological implication

Frontiers in Earth Science
Characterization of the spatiotemporal variability of stable isotopes (δ18O and δD) in the surface water of the Han River Basin (HRB) is critical for tracing basin-scale hydrological cycle processes, identifying moisture-source dynamics, and optimizing ...

Global modelling of H₂ mixing ratios and isotopic compositions with the TM5 model [PDF]

, 2011
The isotopic composition of molecular hydrogen (H2) contains independent information for constraining the global H2 budget. To explore this, we have implemented hydrogen sources and sinks, including their stable isotopic composition and isotope ...

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Determining Biogenic Content of Biogas by Measuring Stable Isotopologues 12CH4, 13CH4, and CH3D with a Mid-Infrared Direct Absorption Laser Spectrometer

Sensors, 2018
A tunable laser absorption spectrometer (TLAS) was developed for the simultaneous measurement of δ13C and δD values of methane (CH4). A mid-infrared interband cascade laser (ICL) emitting around 3.27 µm was used to measure the absorption of the three ...

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

盐生荒漠土壤水稳定氢、氧同位素组成季节动态/Analysis on Seasonal Dynamics of δ18O and δD in Soil Water at a Saline Desert Site in the Southeastern Junggar Basin[J]

, 2014
对准噶尔盆地东南缘降水和土壤水稳定氢、氧同位素组成(δ18O和δD)进行了测定,分析了降水中δ18O和δD值的季节变化规律、表层土壤水中188O和δD值对降水脉冲的动态响应以及不同深度土壤水中188O和δD值的变化特征.结果表明:该区域大气降水线为δD=7.691 δ18O+4.606;降水与表层土壤水中188O和18值表现出明显的季节变化特征;表层土壤水中δ18O和δD值、质量含水量对降水脉冲响应显著,且不同量级的降水导致不同程度的响应.利用LSD法对0～300 ...

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.
