A new technique to partially embed different types of nanoparticles into the surface of polymer materials such as plastics has been developed by University of Leicester scientists.
Researchers developed a pre-embedded solid-solid redox mediation strategy that mixes sulfur and iodine at the nanoscale inside mesoporous carbon to accelerate sulfur conversion in all-solid-state lithium-sulfur batteries. The iodine redox chemistry enabled fast charging, long cycle life, and strong performance at higher active-material loadings across several sulfide solid electrolytes.
A joint research team led by Professors Seunghyun Baik and Joonmyung Choi from the School of Mechanical Engineering of Sungkyunkwan University (SKKU) has developed a new nanocomposite material whose electrical and thermal conductivities increase as it is stretched, successfully applying it to stable heat dissipation for foldable phones.
When light travels through a strongly scattering material, such as biological tissue or other disordered opaque media, it follows many different paths and produces a seemingly random speckle pattern.
Researchers used thermal treatment or laser processing to tune polyacrylonitrile (PAN) fiber mats into separate thermoresistive temperature and piezoresistive pressure-sensing elements for flexible monitoring in high-temperature environments. The platform measured temperatures from 25 to 300 °C and pressures from 0 to 480 kPa, while combined loading above roughly 180 °C and 150 kPa exposed a structural limit.
Your shiny new smartphone and laptop can multitask between video calls, superfast searches, and detailed data crunching because of small, powerful microchips - the digital brains behind every computer's brawn.

A research team led by Dr. Taehoon Kim of the Composites & Convergence Materials Research Division at the Korea Institute of Materials Science (KIMS), headed by President Chul-jin Choi, has collaborated with research teams led by Dr. Seon Joon Kim and Dr. Jaewoo Kim of the Korea Institute of Science and Technology (KIST) to develop an ultrathin composite film that combines electromagnetic interference (EMI) shielding, infrared (IR) stealth, and high mechanical strength.
A review in Advanced Materials examines how biointegrated batteries are being engineered to combine energy storage with electrical stimulation, electrochemical therapy, and controlled drug delivery. The authors highlight how electrode chemistry, flexible and biodegradable materials, hydrogels, conductive polymers, and device architecture determine how these batteries interact with tissue and generate therapeutic outputs.
A review of durable superhydrophobic materials reframes surface design around three dominant failure modes: structural degradation, loss of low-surface-energy chemistry, and coating-substrate interfacial failure. The authors connect fabrication choices with failure-matched testing and examine fluorine-free chemistries, protected architectures, self-healing systems, and interface engineering as routes toward longer service life in demanding environments.
