Flexible Implantable Silicon Carbide Multi‐Electrode Array (MEA) for Cell Multichannel Recording and Cell Ablation

open access: yesAdvanced Materials Technologies, EarlyView.
Flexible silicon carbide (SiC) microelectrode arrays enable high‐fidelity, multichannel cell extracellular recording and precise localized ablation. SiC has been extensively evaluated to persist long‐term in chronic physiological conditions while remaining robust, with excellent electrical and electrochemical stability.

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

open access: yesAdvanced 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 ...

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

open access: yes, 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 ...

Nanocellulose Alleviates Intrahepatic Cholestasis of Pregnancy via Gut Microbiota‐Mediated Bile Acid Homeostasis

open access: yesAdvanced Science, EarlyView.
Nanocellulose, derived from microcrystalline cellulose (MCC) through sulfuric acid hydrolysis or mechanical grinding to produce CNC or CNF, was tested in a rat ICP model. Particularly, CNF improved gut microbiota composition, reduced secondary bile acid metabolism, and restored bile acid homeostasis through modulation of the gut–liver axis.

The structure of the dust layer over the Taklimakan desert during the dust storm in April 2002 as observed using a depolarization lidar [PDF]

open access: yes, 2008
In April 2002, a severe dust storm occurred in the Taklimakan Desert. A large amount of the dust was lifted up by the dust storm and gradually removed in the following few days.

Integrated Opto–Biomechatronics For Single Muscle Fibre Structure‐Function Assessment: The MyoRobot 3.0

open access: yesAdvanced Science, EarlyView.
We present the MyoRobot 3.0, an advanced platform that combines high‐resolution imaging with automated mechanical testing to improve the accuracy of single muscle fibre analysis. The system tracks fibre diameter changes during stretch, preventing major stress miscalculations.

NMI Regulates Adipose Adaptive Thermogenesis Through TLR4/IRF3 Signaling to Promote Obesity

open access: yesAdvanced Science, EarlyView.
Adipose tissue‐derived NMI is secreted under metabolic stress and suppresses adaptive thermogenesis through TLR4/IRF3 signaling, repressing the PPARα/PGC‐1α/UCP1 thermogenic transcriptional program. Genetic ablation or anti ‐ NMI monoclonal antibody treatment enhances energy expenditure, protects against DIO, and ameliorates adipose tissue inflammation,
