Multipulse lightning currents and metal-Oxide arresters
, 1997 Multiple stroke lightning ground flashes can impose surges of exceptional severity on exposed distribution surge arresters. This paper describes a series of tests on metal-oxide (MO) arresters and varistors to study surface flashover mechanisms.

FEBS Open Bio, EarlyView.UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Researches on grounding modes of the AC/DC hybrid system with various distributed renewable energy
The Journal of Engineering, 2019 With the considerable demand for distributed renewable energy and the significant increase of generalised DC loads, such as IT equipment, DC air-conditioner, electric vehicle, the traditional AC distribution network is no longer efficient.

Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...
