Design of High‐Performance MnCo1.5Cu0.5O4 Spinel Contact Material with Optimized Electrical Conductivity and Thermal Stability for Solid Oxide Electrolysis Cells by Cu Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cu‐doped spinel MnCo1.5Cu0.5O4 exhibits excellent conductivity and stability as SOC contact material. After 1000‐h aging at 850 °C, the contact layer maintains a 10 mΩ cm2 ASR value, and a single‐cell stack achieves a H2O/CO2 co‐electrolysis power density of 0.52 W cm−2.

Occupation du sol et organisation du monde chez les Small Nambas du Sud Malakula (Vanuatu)

, 1998
In the mid 1970's, the Small Nambas of South Malakula were the last heathens to continue with the old Melanesian ways of living. In this pyramidal society, social status and spiritual beliefs were mixed. They were represented on the ground by artifacts and various symbolic taboos. The whole area was divided between pig and human territories.

One‐Pot Spray Pyrolysis Fabrication of Multi‐Phase Lithium Manganese Oxide Microsphere Cathodes for Enhanced Lithium‐Ion Battery Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sr‐LMO microspheres were synthesized by one‐pot spray pyrolysis, forming multi‐phase lithium manganese oxide with Sr‐doped LiMn2O4, Sr2Mn2O5, and Li2MnO3‐like domains. This structure refines particles, suppresses Jahn–Teller distortion, and adds Li+ pathways, delivering superior cycling stability and rate performance over undoped and commercial LMO ...

Clinical outcomes and learning curve of MRgLITT system for drug‐resistant epilepsy in China: A single‐center retrospective study

Epilepsia Open, EarlyView.
Abstract Objective Magnetic resonance‐guided laser interstitial thermal therapy (MRgLITT) is a minimally invasive technique that allows for real‐time magnetic resonance imaging (MRI) monitoring and precise ablation of epileptogenic lesions. This study reports our initial clinical experience with a domestically developed MRgLITT system in patients with ...

Integrating Remote Sensing and Machine Learning for Enhanced Surface Urban Heat Island Analysis and Its Impact on Building Energy Demand

Energy Science &Engineering, EarlyView.
Satellite (MODIS) mapping links Urban Heat Island (UHI) intensity to city‐scale energy demand—higher daytime cooling demand and altered nighttime heating demand—supporting targeted mitigation and planning. ABSTRACT This study examines the surface urban heat island (SUHI) effect on building energy consumption in Tehran from 1998 to 2024, utilizing MODIS

Catalyst Functionalization for Elevating Performance in Ammonia Protonic Ceramic Fuel Cells via Relay Thermo‐Electrocatalysis

Exploration, EarlyView.
Direct ammonia proton ceramic fuel cell (NH3‐PCFC) typically underperforms at intermediate temperatures due to slow ammonia decomposition at the anode. By applying a Ru/CZ4 catalytic layer, this study enhances ammonia decomposition, with NH3‐PCFC power density at 650°C reaching 93.7% of H2‐fueled PCFC, offering valuable insights into optimizing fuel ...

Multifunctional ionic liquid boosts the efficiency of hole transport layer‐free carbon‐based perovskite solar cells beyond 20%

FlexMat, EarlyView.
HTL‐free carbon‐based PSCs are promising in stability but limited by efficiency. Systematic screening identifies DMAFo as an optimized ionic‐liquid additive: the DMA+ regulates lattice distortion and relieves residual stress, while Fo‒ passivates halide vacancies, and ameliorates band‐alignment.
