Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

The Bionic Interface: Considering the Material Mediated Electrical Stimulation of Stem Cells

open access: yesAdvanced Materials, EarlyView.
Electrical stimulation directs stem cell fate in tissue engineering. Cellular responses are influenced by membrane properties, intrinsic cell state, material charge‐transport characteristics, and the applied electrical signal. Additionally, a material’s ability to inject, store, and redistribute charge further modulates these responses.

The Co-ordination of Swimmeret Movements in the Crayfish, Procambarus Clarkii (Girard) [PDF]

open access: yes, 1960
1. Electrical activity recorded in the first roots of the abdominal nerve cord show bursts of activity which accompany rhythmic movements of the swimmerets. These bursts persist when a root is cut distal to the electrodes. 2.

Neuromorphic Visual Receptive Field Hardware with Vertically Integrated Indium‐Gallium‐Zinc‐Oxide Optoelectronic Memristors over Silicon Neuron Transistors

open access: yesAdvanced Materials, EarlyView.
This work proposes neuromorphic visual receptive field hardware with vertically integrated amorphous In‐Ga‐Zn‐O optoelectronic memristors and Si neuron transistors for retina‐inspired visual processing. The visual receptive field array, comprising ON‐ and OFF‐type cells, facilitates edge detection, thereby enhancing perception in complex images, such ...

Endoscopic Resection of the Tarsal Tunnel Ganglion

open access: yesArthroscopy Techniques, 2016
The tarsal tunnel ganglion is a cause of posterior tarsal tunnel syndrome. Open resection of the ganglion calls for release of the flexor retinaculum and dissection around the tibial neurovascular bundle. This can induce fibrosis around the tibial nerve.
