Rational Design of Bearing‐Construction Nanoreactor for Photocatalytic Application
Ag nanoparticle supported by an inner SiO2 core and guarded by an outer TiO2 shell: this creative SiO2‐Ag@TiO2 catalyst was synthesized by a partially chemical template‐etching method. Based on related experimental results, SiO2‐Ag@TiO2 exhibits excellent photoactivity.

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...

Pollution to Solution: Understanding and Addressing Microplastic Contamination in the Environment
ABSTRACT In general, plastic pollution results from the unintentional release of macroplastic materials into the environment as well as the deliberate production and usage of small plastic particles (micro‐ and nano‐sized plastic particles) in a variety of consumer products micro and nanoplastics in filtrate freshwater and marine environments because ...

The Promise of Solid Lubricants for a Sustainable Future
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?
