Abstract Hunger and chronic undernourishment impact over 800 million people, which translates to ≈10.7% of the world's population. While countries are increasingly making efforts reduce poverty hunger by pursuing sustainable energy agricultural practices, a third food produced around globe still is wasted never consumed. Reducing shortages vital in this effort often addressed development genetically modified produce or chemical additives inedible coatings, create additional health...
Abstract Covalent organic frameworks (COFs) have emerged as an exciting new class of porous materials constructed by building blocks via dynamic covalent bonds. They been extensively explored potentially superior candidates for electrode materials, electrolytes, and separators, due to their tunable chemistry, tailorable structures, well‐defined pores. These features enable rational design targeted functionalities, facilitate the penetration enhance ion transport. This review provides...
Natural wood has served as a foundational material for buildings, furniture, and architectural structures millennia, typically shaped through subtractive manufacturing techniques. However, this process often generates substantial waste, leading to inefficiency increased production costs. A potential opportunity arises if complex can be created additive processes. Here, we demonstrate an additive-free, water-based ink made of lignin cellulose, the primary building blocks natural wood, that...

Corrosion by sulfur compounds is a long-standing challenge in many engineering applications. Specifically, designing coating that protects metals from both abiotic and biotic forms of corrosion remains an elusive goal. Here we report atomically thin layers (∼4) hexagonal boron nitride (hBN) act as protective to inhibit the underlying copper (Cu) surfaces (∼6-7-fold lower than bare Cu) (sulfuric acid sodium sulfide) (sulfate-reducing bacteria medium) environments. The resistance hBN...
3D printed, stimuli-responsive materials that reversibly actuate between programmed shapes are promising for applications ranging from biomedical implants to soft robotics.
