Ammonia Gas Sensor Fabricated by Multifunctional ZnO/GO Nanocomposites for Long‐Term, Self‐Powered Monitoring

open access: yesAdvanced Science, EarlyView.
Zinc oxide/graphene oxide (ZnO/GO) nanocomposites serve as a gas‐sensitive film for ammonia sensing and as high‐performance electrode materials in supercapacitors, simultaneously. A wearable contact‐separated triboelectric nanogenerator is designed to directly drive the ZnO/GO nanocomposites‐based ammonia sensor.

Button battery lodged in Meckel's diverticulum

open access: yesJournal of Pediatric Surgery Case Reports, 2018
Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract. It is relatively uncommon, however, for patients to become symptomatic and rarer still for foreign bodies to become lodged within a Meckel's diverticulum.

Bioinspired Ultrastrong and Ion‐Selective Gel Electrolytes by Interfacial Coacervation for High‐Performance Lithium‐Metal Batteries

open access: yesCarbon Energy, EarlyView.
An ultrastrong, hierarchically nanoporous gel polymer electrolyte (GPE) was fabricated via poly(ionic liquid)‐induced interfacial coacervation of cellulose nanofibrils. Its cascade ion‐conduction network enables dual‐mode Li⁺ transport via nanoconfinement and interstitial hopping. The GPE enables stable cycling of high mass loading battery (LiFePO₄, 16
