Observation of Catalytic Variability of Single Enzyme Zeolitic Imidazole Framework‐8 Nanoparticles

Advanced Materials Interfaces, EarlyView.
A microwell‐based fluorescence method characterizes the catalytic activity of single enzyme zeolitic imidazole framework‐8 (ZIF‐8) nanoparticles (NPs). Horseradish peroxidase (HRP) and bovine serum albumin (BSA) are loaded into ZIF‐8 NPs and reveal subpopulations of catalytic activity at single‐particle resolution.

Programmable Microscale Actuation of Hydrogels With Tunable Response via Printing on Particles

Advanced Materials Technologies, EarlyView.
We fabricate microscale hydrogels with precisely tunable phase transition temperatures (23–60 °C) by particle‐templated two‐photon polymerization using chemically tailored inks. Multi‐material printing enables stepwise thermal actuation through sequential volume changes at distinct VPTTs, while pH‐dependent hysteresis drives anisotropic actuation with ...

Optimizing Ordering Policies for Imperfect Inventory Systems Integrating Trade Credit and Carbon Emission [PDF]

International Journal of Mathematical, Engineering and Management Sciences
Reducing carbon emissions is about protecting the future, in which the greatest treasures are clean air, a stable temperature and a thriving planet, not only about saving the environment.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
