Investigation on temperature-dependent optoelectronic properties of MoSe nanosheet/Si heterojunction photodetectors.

MoSe nanosheet/Si heterojunction photodetectors were fabricated by a mechanical exfoliation method, and their electrical and optical properties at different temperatures were investigated. It was found that the MoSe nanosheet/Si heterojunction device exhibited excellent rectification characteristics at room temperature, and the rectification ratio gradually decreased with the decrease of temperature. The temperature-dependent electrical properties of the MoSe/Si heterojunction device were actually caused by the inhomogeneity of the potential barrier.

Aluminum surface lattice resonances for enhanced near-infrared performance in asymmetric environments.

Aluminum (Al) is a cost-effective alternative to noble metals for plasmonics, particularly in the ultraviolet (UV) and visible regions. However, in the near-infrared (NIR) region, its performance is hindered by interband transitions (IBTs) at around 825 nm, leading to increased optical losses and broad resonances. Surface lattice resonances (SLRs) offer a promising solution by enhancing the plasmonic quality factor (-factor) through coherent coupling of localized surface plasmon (LSP) modes with Rayleigh anomalies.

In vivo self-assembled siRNAs ameliorate neurological pathology in TDP-43-associated neurodegenerative disease.

Abnormal accumulation of TAR DNA-binding protein-43 (TDP-43) is a hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Small interfering RNAs (siRNAs) targeting TDP-43 offer potential therapeutic strategies for these diseases. However, efficient and safe delivery of siRNAs to the central nervous system (CNS) remains a critical challenge.

H5N1 influenza virus-like particles based on BEVS induce robust functional antibodies and immune responses.

Avian influenza virus infections pose a potential pandemic threat. The currently licensed vaccines have inherent limitations, emphasizing the urgent need for improved influenza vaccines. Here, we developed a novel hemagglutinin (HA) virus-like particle (VLP) vaccine candidate through the baculovirus expression vector system (BEVS).

Copine family members: Their molecular mechanisms in tumor progression and therapy resistance and their value in tumor diagnosis and prognosis evaluation.

Malignant tumors present a major global health burden, as they generally have a poor prognosis, and the efficacy of available treatments is limited. Copine family members (CPNEs) play crucial roles in the regulation of tumor cell proliferation, metastasis, and therapeutic resistance, as well as in tumor diagnosis and prognostic risk stratification. CPNEs can facilitate tumor cell survival by regulating cell cycle progression and cell death.
