Coating‐Free Nanoscratching for Liquid‐Crystal Alignment on PCB‐Compatible Millimeter‐Wave Reflective Unit Cells

Advanced Materials Technologies, EarlyView.
Direct nanoscratching with a 500 nm diamond lapping film creates groove‐guided liquid‐crystal alignment interfaces on PCB‐compatible Cu‐patterned RF substrates within minutes, eliminating polymer coating and high‐temperature baking. The coating‐free process enables optical/molecular alignment validation and voltage‐programmable 28 GHz reflection‐phase ...

The Evolution of the Mars Year (MY) 35 Anomalous Spring Dust Storm and Its Influence on the Chryse and Utopia Plains

Remote Sensing
Dust storms have a significant impact on the Martian atmosphere and climate. Previous studies have found that regional and global dust storms mainly occur in the Mars perihelion season.

Thermospheric density responses to Martian dust storm in autumn based on MAVEN data

Geodesy and Geodynamics, 2022
The unique seasonal surface dust storms on Mars have a significant impact on the Martian atmosphere. However, due to the lack of observations, semi-empirical models are difficult to simulate the density changes in the thermosphere with the existence of ...

Optimizing Stratification in Binary Colloidal Supraparticles

Advanced Science, EarlyView.
Supraparticles from binary particle populations show stratification when dried at high Péclet numbers. In spray‐dried systems at high initial particle concentration and fast drying conditions optimal combinations of particle size ratios and volume fractions that produce maximal stratification are found both in experiment and simulation, contrasting the

Mesoporous Catalytic‐Adsorptive Nanoregulator Orchestrates Biofilm eDNA/LPS Disassembly and TLR9/TLR4 Immune Reprogramming to Resolve Diabetic Foot Infections

Advanced Science, EarlyView.
Chronic diabetic wounds are hindered by a “dual trap” of biofilm resistance and hyperinflammation. A mesoporous catalytic‐adsorptive nano‐regulator is developed to dismantle this barrier through simultaneous eDNA degradation and LPS sequestration. By silencing TLR4/9‐mediated signaling, the platform clears resilient pathogens and reprograms the immune ...

Self‐Sustaining Lactate Depletion Nanoplatform Remodels Tumor Microenvironment and Augments Synergistic Photodynamic/Photothermal/Chemodynamic/Starvation Therapy for Eradication of Colon Cancer

Advanced Science, EarlyView.
The HILA nanoplatform integrates HMnO2, LOX, and ICG to orchestrate multimodal therapy (starvation, chemodynamic, photodynamic, and photothermal) for achieving efficient colon cancer eradication. The established HMnO2‐LOX catalytic cycle continuously consumes lactate, acidifys microenvironment, relieves hypoxia, and generats reactive oxygen species ...

Atmospheric controls on mineral dust emission from the Bodélé Depression, Chad: The role of the low level jet [PDF]

, 2005
Atmospheric aerosols play an important though uncertain role in the Earth's climate system. The Bodélé Depression in Chad stands out as the planet's largest source of dust, yet very little is known about the atmospheric circulation that maintain this ...
