Nitrogen ion implanted InP based photo-switch

Optics Express, 2012
An Indium Phosphide-based device, switched by telecommunication wavelength laser pulses capable of operating at microwave frequencies up to 15 GHz has been designed and fabricated. Initial results confirm that using high energy nitrogen ion implantation to create EL-2 type trapping levels produces a photocarrier recombination time of a few picoseconds.

Bio‐Inspired Biopolymeric Implantable Platform for Localized and Sustained Drug Delivery in Solid Tumor Treatment

Advanced Functional Materials, EarlyView.
A bio‐inspired biopolymeric implantable drug delivery platform enables localized and sustained release of 7‐ethyl‐10‐hydroxycamptothecin (SN‐38) in solid tumor treatment. The three‐dimensional (3D) structured crosslinked‐chitosan implants are fabricated via 3D‐printed molds and provide drug release over 3 months, significantly inhibiting tumor growth ...

Dose-effect relationship of edible fungi with low-energy heavy-ion implantation

Fushe yanjiu yu fushe gongyi xuebao, 2021
To reveal the dose-effect relationship of edible fungi via low-energy heavy-ion implantation, the conidia of three species of edible fungi were irradiated with 15 keV nitrogen ions at different dosages (0, 2, 4, 6, 8, 10, 12, and 14)×1015 cm-2.
