Heterostructure‐Engineered Conductive MOFs Coupled with MoSe2@MXene Framework for Efficient and Selective Lithium Extraction from Salt Lake Brine via Capacitive Deionization

Advanced Science, EarlyView.
This schematic illustrates a capacitive deionization (CDI) system for the selective extraction of lithium from salt‐lake brine. The system employs a cathode fabricated from the Fe‐THBQ@MoSe2@MXene composite alongside an activated carbon (AC) anode. Upon applied voltage, the cathode demonstrates high efficiency in capturing Li+ ions while effectively ...

Olivine or Impact Melt: Nature of the "Orange" Material on Vesta from Dawn

, 2013
NASA's Dawn mission observed a great variety of colored terrains on asteroid (4) Vesta during its survey with the Framing Camera (FC). Here we present a detailed study of the orange material on Vesta, which was first observed in color ratio images ...

Spectral Energy Distributions of T Tauri and Herbig Ae Disks: Grain Mineralogy, Parameter Dependences, and Comparison with ISO LWS Observations [PDF]

, 2000
We improve upon the radiative, hydrostatic equilibrium models of passive circumstellar disks constructed by Chiang & Goldreich (1997). New features include (1) account for a range of particle sizes, (2) employment of laboratory-based optical constants of

In Situ Liquid‐Cell Transmission Electron Microscopy Insights Into Lithium‐Ion Battery Materials Degradation: Challenges and Emerging Solutions

Advanced Science, EarlyView.
Lithium‐ion battery degradation arises from complex, localized processes during operation, limiting long‐term performance. In situ electrochemical liquid cell TEM provides unique access to these mechanisms. This review summarizes degradation phenomena revealed by liquid cell TEM, traces the evolution of the three main cell designs, compares their ...

Trace element geochemistry of ordinary chondrite chondrules: the type I/type II chondrule dichotomy [PDF]

, 2015
We report trace element concentrations of silicate phases in chondrules from LL3 ordinary chondrites Bishunpur and Semarkona. Results are similar to previously reported data for carbonaceous chondrites, with rare earth element (REE) concentrations ...

Effect of Imidazolium Concentration in Densely Functional Polymer Binder on Robust Electrochemical Kinetics and Cycling Performance of Lithium Iron Phosphate Cathode

Advanced Energy and Sustainability Research, EarlyView.
The improved performance of the cathodic half‐cell containing poly(oxycarbonylmethylene 1‐allyl‐3‐methylimidazolium) (PMAI) binder (PMAI/LFP) is attributed to the ion conduction properties of imidazolium‐functionalized polymer, which participates in cathode‐electrolyte interphase (CEI) formation as confirmed by X‐ray photoelectron spectroscopy and ...

ECO: A new reference model of dry olivine electrical conductivity

Solid Earth Sciences
Electrically Conductive Olivine, ECO, is presented as a new reference model for the electrical conductivity of dry olivine. The model takes into account the prevailing redox state, temperature and pressure in the upper mantle, as well as their effects on

LiMnxFe1−XPO4 Anodefree Batteries: A Scalable, Low Cost, Energy Dense Lithium Cell Design

Batteries &Supercaps, EarlyView.
The development of next‐generation lithium batteries with even greater performance (storage capacity and lifetime) is required to open up new (demanding) applications such as electric aircraft and drones. In this study, we show that the anodefree LiMnxFe1−xPO4 cell design dramatically improves energy density while reducing manufacturing cost and design
