Wearable ultrasound devices for therapeutic applications
Shanghai Jiao Tong University Journal CenterPeer-Reviewed Publication
Wearable ultrasound devices represent a transformative advancement in therapeutic applications, offering noninvasive, continuous, and targeted treatment for deep tissues. These systems leverage flexible materials (e.g., piezoelectric composites, biodegradable polymers) and conformable designs to enable stable integration with dynamic anatomical surfaces. Key innovations include ultrasound-enhanced drug delivery through cavitation-mediated transdermal penetration, accelerated tissue regeneration via mechanical and electrical stimulation, and precise neuromodulation using focused acoustic waves. Recent developments demonstrate wireless operation, real-time monitoring, and closed-loop therapy, facilitated by energy-efficient transducers and AI-driven adaptive control. Despite progress, challenges persist in material durability, clinical validation, and scalable manufacturing. Future directions highlight the integration of nanomaterials, 3D-printed architectures, and multimodal sensing for personalized medicine. This technology holds significant potential to redefine chronic disease management, postoperative recovery, and neurorehabilitation, bridging the gap between clinical and home-based care.

Removal of hemicellulose from alkaline lignin improved electrochemical performance of hard carbon for sodium-ion battery application
Songshan Lake Materials LaboratoryPeer-Reviewed Publication
A research team from Queensland University of Technology has developed an effective strategy to enhance sodium-ion batteries (SIBs) by using lignin, a natural polymer, as sustainable precursor for hard carbon anodes. Lignin, which is a by-product of processing biomass, has chemical treated to eliminate its hemicellulose. The purified lignin was used to make hard carbon (HC) with improved structural properties, like short-range graphitic layers, fewer defects, and a better pore structure that facilitates sodium storage. Their findings demonstrated that removing hemicellulose significantly boosts the initial Coulombic efficiency (ICE, 76.1%) and the reversible capacity of the hard carbon (277.5 mAh g-1) , along with 86.1% capacity retention after 250 cycles. This study highlights that hemicellulose removal is a crucial first step in improving the electrochemical performance of lignin-derived HC.

Cooling paint harvests water from thin air
University of SydneyPeer-Reviewed Publication
University of Sydney and startup Dewpoint Innovations have developed paint-like substance that reflects 97 percent of sunlight and can cool the painted surface by up to six degrees below ambient temperature, cooling building and passively extracting water. The innovation could help cool urban heat islands and supplement tank water.
