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.
Researchers reviewed advances in alloy-based anodes for rechargeable magnesium batteries, comparing Mg-free hosts, Mg-containing alloys and alloy-derived surface modifications as routes to improve reversibility, Mg²? transport and electrolyte compatibility. The review finds that material structure and interphase chemistry strongly influence performance, while higher alloy-anode operating potentials can reduce full-cell voltage, and practical validation remains a major research priority.
A research team at the University of Vienna led by physicist Jani Kotakoski demonstrates how the shape of nanopores in hexagonal boron nitride - the electrically insulating counterpart to graphene, also known as "white graphene" - can be precisely controlled at the atomic level. Electron irradiation in ultra-high vacuum creates circular pores, while adding small amounts of oxygen yields triangular pores. The nanopore engineering presented in the journal Nature Communications thus unlocks new applications in filtration, DNA sequencing, catalysis, and quantum technologies.
