Genetic Impacts on the Structure and Mechanics of Cellulose Made by Bacteria

open access: yesAdvanced Science, EarlyView.
A genetic mutation in a protease of a cellulose‐overproducing evolved bacterium significantly affects the proteome, structure, and mechanical properties of bio‐fabricated cellulose pellicles. By overexpressing synthase proteins that build the cellulose‐forming biological machinery of the cell, the evolved bacterium generates dense, stiff, and strong ...

A Self‐Adaptive Reconfigurable Metasurface for Electromagnetic Wave Sensing and Dynamic Reflection Control

open access: yesAdvanced Science, EarlyView.
Reconfigurable metasurfaces typically require human intervention or complex, resource‐heavy processes. This innovative self‐adaptive metasurface senses an incident wave's direction, adjusting reflection in real‐time using a simple electronics module. It eliminates external controllers, reducing response time, energy consumption, and costs. Applications

Harnessing Dynamic Electrostatic Fields for Energy Generation with Diode Cells

open access: yesAdvanced Science, EarlyView.
Stationary diode cells (DiCes) are fabricated to harvest energy from dynamically changing electrostatic fields by leveraging the unique current modulation properties of diodes. The DiCes can directly output DC voltage and current. Their applications range from energy harvesting and powering implanted devices to use in sensors.
