Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

open access: yesAdvanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

open access: yesAdvanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation

open access: yesAdvanced Science, EarlyView.
A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...

Inside the Microreactor: In Situ Real‐Time Observation of Vapor–Liquid–Solid Growth of Monolayer TMDCs

open access: yesAdvanced Science, EarlyView.
In situ observation of VLS growth in a confined microreactor reveals various growth modes of monolayer TMDCs, including abnormal ribbon growth and particle‐driven growth. The confined space and precursor balance influence droplet behavior and growth dynamics, offering new insights into the controlled synthesis of TMDCs via the VLS mechanism.

Production of Titanium Oxide by Alkali Treatment

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1958
目的:従来,酸化チタンは,イルメナイト,砂鉄,チタンスラグ等のチタン原料を濃硫酸で分解する酸法で作られている。われわれは,従来の方法とは全く異なったカセイソーダと過酸化水素とによって,TiO2を溶出するアルカリ法とでもいうべき新方法の工業的可能性を検討し,その方法の確立を目的とした。特長:酸を使用しないため,鉄分で汚染されない製品がえられる。また,酸法と異なって,直接,加水分解によって被覆力,着色力の強いルチル型の製品がえられる。結果:メタチタン酸ナトリウムの加水分解による水和酸化チタンは,カセイソーダと過酸化水素に可溶化することがわかり,アルカリ法による酸化チタン製法の主工程を確立し,優秀な製品がえられた。
