Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

Advanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

5-Hydroxytryptamine receptor 1D overexpression exacerbates gastric cancer proliferation, invasion, and angiogenesis by activating the Wnt/β-catenin signaling

BMC Cancer
Dysregulation of 5-Hydroxytryptamine and its receptors play important roles in the development and progression of malignant tumors. However, the biological role and underlying molecular mechanism of 5-Hydroxytryptamine Receptor 1D (HTR1D) gastric cancer (

Study of the winter 2005 Antarctica polar vortex [PDF]

, 2009
During winter and springtime, the flow above Antarctica at high altitude (upper troposphere and stratosphere) is dominated by the presence of a vortex centered above the continent. It lasts typically from August to November.

High-altitude medicine

Indian Journal of Occupational and Environmental Medicine, 2010
Sojourns to high altitude have become common for recreation and adventure purposes. In most individuals, gradual ascent to a high altitude leads to a series of adaptive changes in the body, termed as acclimatization. These include changes in the respiratory, cardiovascular, hematologic systems and cellular adaptations that enhance oxygen delivery to ...

The Impact of Catalyst Layer Composition and Structure on Performance and Durability of PEMWE Anodes

Advanced Materials Technologies, EarlyView.
This article explores a new type of anode for water electrolysis that uses less iridium, a rare and expensive metal. By combining stable iridium oxide with platinum and carbon‐based materials, the authors create a catalyst layer that maintains strong performance.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Activation of notch signaling pathway is a potential mechanism for mucin2 reduction and intestinal mucosal barrier dysfunction in high-altitude hypoxia

Scientific Reports
High-altitude hypoxia can cause gastrointestinal issues and damage the intestinal mucosal barrier, which is crucial for digestion and nutrient absorption. The Notch signaling pathway affects this barrier’s integrity. This study explores the Notch pathway’
