Micro-Raman structural responses of nano-mechanical properties of different coal grades
Meikuang Anquan, 2022 The mechanical properties of coal are heterogeneous and in multi-scale. Understanding the coal mechanical properties and structure in nano-scale is the key to know the fracturing transformation and crack expansion mechanisms of coal reservoirs.

The Immobilization of Hyaluronic Acid in 3D Hydrogel Scaffolds Modulates Macrophage Polarization
Advanced Biology, EarlyView.This study explores the use of collagen‐hyaluronic acid (HA) hydrogels for the 3D culture of macrophages, providing a useful tool for modelling macrophage behavior in tissues and diseases. It highlights how hydrogel composition, mechanical properties, and preparation methods influence macrophage behavior, revealing for the first time that HA's ...

Advanced Biology, EarlyView.The unrolling of the peltate leaves in Syngonium podophyllum is analyzed and quantified (left‐hand side to center). These measurements serve to verify a mathematical model for leaf unrolling based on the model used in Schmidt (2007). An additional formula for obtaining a layer mismatch from a prescribed radius is derived.
