How Macroeconomic Instability Lowers Child Survival [PDF]

The reduction of child mortality is one of the most universally accepted millennium goals. However, a significant debate came out on the means of reaching it and on its realism with regard to the situation of most of the least developed countries.

Uncovering the Critical Role of Ni on Surface Lattice Stability in Anionic Redox Active Li1.2Ni0.2Mn0.6O2

Carbon Energy
Anionic redox reaction (ARR) can provide extra capacity beyond transition metal (TM) redox in lithium‐rich TM oxide cathodes. Practical ARR application is much hindered by the structure instability, particularly at the surface.

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.

Stability and grouting treatment of collapse goaf in shallow coal seams

Discover Applied Sciences
Based on the key stratum theory, a “short masonry beam” mechanical model was established to analyze the surface subsidence mechanism above the studied coal-mine goaf in a selected mining area of Ningxia, China. Rather than treating the short masonry beam

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Spatially Regulated Lithium Plating via Li2O‐Rich Interphase Enables Durable Fast‐Charging Hybrid Lithium Batteries

Advanced Functional Materials, EarlyView.
A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

Advanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Comparing the Onset of Pre-Activity of Leg Muscles between Athletes with Functional Ankle Instability and Healthy Athletes During Landing from a Jump

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2017
BACKGROUND AND OBJECTIVE: Functional ankle instability (FAI) is one of the most commonly debilitating complications of acute ankle sprain, which often results in the athlete staying away from exercise for a while. Disorder in the mechanism of feedforward

Study on the instability characteristics and influencing mechanism of coal-rock parting-coal structure under triaxial loading

Scientific Reports
Rockburst accidents are highly likely to take place during the mining of coal seams in bifurcated area. A conventional triaxial testing machine and an acoustic emission (AE) monitoring system are employed to investigate the failure and instability ...
