Unraveling the Morphological and Functional Maturation Mechanisms Underlying Human Neural Development Using iPSCs‐Derived Neuronal Model

open access: yesAdvanced Science, EarlyView.
Using human induced pluripotent stem cells (hiPSCs)‐derived neuronal model, Tian and colleagues reveal that voltage‐gated calcium channels Cav1.2 and Cav1.3, and their mediated calcium ion influx, are essential for early morphogenesis of human neuronal development, while ECEL1 underlies human neuronal functional developmental maturation through CALM3 ...

Cellulose-binding domains as a tool for paper recycling [PDF]

open access: yes, 2003
Treatment of secondary paper fibres with cellulose-binding domains allows for improvements of pulp drainability and of paper mechanical properties. The interfacial system fibrewater- fibre, and after drying, fibre-air-fibre, may be affected by the CBD ...

From Grave to Cradle: Kombucha Waste for Sustainable Electronics

open access: yesAdvanced Science, EarlyView.
This study introduces a sustainable method to purify kombucha bacterial cellulose (KBC) with sodium bicarbonate and hydrogen peroxide, avoiding harsh chemicals. KBC films are patterned with gold and function as pressure sensors for flatfoot gait detection. At the end‐of‐life, the KBC‐based device biodegrades in soil, leaving environmentally benign gold

Photocatalytically Activated Cu‐N1S3 Single‐Atom Nanozyme: Enhancing Enzyme Activities and Antibacterial Synergy for Highly Efficient Fruit Preservation

open access: yesAdvanced Science, EarlyView.
This study presents S‐coordinated Cu single‐atom nanozymes (Cu/CNS) fabricated via mild photocatalytic self‐assembly strategy. The nanozyme exhibits exceptional multi‐enzyme activity and near‐perfect antimicrobial efficacy. Incorporated into chitosan‐gelatin film, it enables pH‐responsive, broad‐spectrum fruit preservation, more than doubling the shelf‐

The Effects of Washing between Hydrogen Peroxide Bleaching Stages on Brightness Reversion of a Spruce High-Yield Pulp [PDF]

open access: yes, 1996
The final brightness of a bleached high-yield pulp paper product is a very important factor in determining the quality of the pulp and the product. If the brightness of this product tends to revert in time, then the quality of the product could be viewed

Elevator‐Like Hollow Channels in Porous Scaffolds Accelerate Vascularized Bone Regeneration via NETs‐Fibrin‐Mediated Macrophage Recruitment

open access: yesAdvanced Science, EarlyView.
This study demonstrates that how hollow‐channel scaffolds promote vascularized bone regeneration via an immunomodulatory mechanism. The channel structures facilitate the formation of a neutrophil extracellular traps‐fibrin scaffold that recruits vascular endothelial growth factor A (VEGF‐A)‐secreting M2 macrophages to drive angiogenesis. Combining this

Mountain bananas from the french west indies [PDF]

open access: yes, 2007
Banana production is a key economic resource in the French West Indies. It is essential that growers in this region enhance their sales by proposing new products-such as mountain bananas-in response to high market competition from other exporting regions

A Tangentially Sensitive Tactile Sensor Reveals the Stick‐Slip Mechanism and Enhances Robotic Tactile Sensing

open access: yesAdvanced Science, EarlyView.
An ultralight, multilayer anisotropic tactile sensor—an artificial Pacinian corpuscle—exhibits ultrahigh tangential sensitivity (1022 kPa−1) and spatiotemporal sensing. It discriminates static, sliding, and rolling contacts, detects incipient stick–slip via high‑frequency signatures, and enhances robotic touch (100%/98.18% accuracy for active/passive ...
