Room-temperature-operating highly sensitive mid-wavelength infrared (MWIR) photodetectors are utilized in a large number of important applications, including night vision, communications, and optical radar. Many previous studies have demonstrated uncooled MWIR using 2D narrow-bandgap semiconductors. To date, most these works atomically thin flakes, simple van der Waals (vdW) heterostructures, or p-n junctions as absorbers, which difficulty meeting the requirements for state-of-the-art with...
Abstract Simultaneously mitigating both photovoltage and photocurrent losses is crucial for organic solar cells (OSCs) to approach the Shockley–Queisser limit of ideal efficiency. Incorporating a narrower bandgap nonfullerene acceptor (NFA) as guest component into host donor:NFA system broadens absorption spectrum. However, this can also increase nonradiative decay rate according energy‐gap law. In work, ternary OSCs are constructed by combining narrow AQx‐2F (as NFA) with lower eC9 NFA),...
Oral delivery of peptide/protein drugs has attracted worldwide attention due to its good patient compliance and convenience administration. Orally administered nanocarriers always encounter the rigorous defenses gastrointestinal tract, which mainly consist mucus epithelium barriers. However, diametrically opposite surface properties are required for penetration high epithelial uptake. Here, bovine serum albumin (BSA) is adsorbed cationic liposomes (CLs) form protein corona (PcCLs). The aim...
Significance Lipid vesicles such as liposomes are widely present in biological systems and drug delivery applications. Numerous studies have focused on their roles intercellular communication, signaling, trafficking. Little is known, however, about the correlation between temperature transport rate of these media. Here, we report a temperature- rigidity-mediated rapid mechanism by which attain optimal diffusivity near phase transition temperature. Remarkably, with around body observed to...
Abstract Silicon (Si)‐based photodetectors are cost‐effective, eco‐friendly, and compatible with on‐chip complementary metal‐oxide‐semiconductor (CMOS) technology. However, expanding their photoresponse into the short‐wavelength‐infrared region beyond 1.1 µm remains challenging because of intrinsic bandgap Si. In this study, an ion implantation sulfur‐doped Si‐based infrared photodetector featuring a blocked impurity band (BIB) structure is investigated. The detector achieves extended...
Solid-state infrared-to-visible photon up-conversion is important for spectral-tailoring applications. However, existing systems not only suffer from low efficiencies and a need high excitation intensity, but also exhibit limited selection of materials complex fabrication processes. Herein, we propose sensitizer with bulk-heterojunction structure, comprising both an energy donor acceptor, triplet-triplet annihilation devices. The occurs through charge separation at the donor-acceptor...
Neural stem cells (NSCs) are critical for brain development and maintenance of neurogenesis. However, the molecular mechanisms that regulate NSC proliferation differentiation remain unclear. Mysm1 is a deubiquitinase essential self-renewal several cells. It unknown whether plays an important role in NSCs. Here, we found was expressed NSCs its expression increased with age mice. Mice knockdown by crossing floxed mice Nestin-Cre exhibited abnormal microcephaly. deletion promoted apoptosis,...
The very long wavelength infrared (VLWIR, >14 µm) spectral band is an indispensable part of new-generation remote sensing. Mercury cadmium telluride (HgCdTe or MCT) has shown excellent potential across the entire band. However, dark current, which extremely sensitive to technological level and small Cd composition, severely limits performance VLWIR HgCdTe photodiodes. In this study, cut-off wavelengths up 15 µm for devices with novel P-G-I (including wide bandgap p-type cap layer, grading...
Laser scanning 3D imaging technology, because it can obtain accurate three-dimensional surface data, has been widely used in the search for wrecks and rescue operations, underwater resource development, other fields. At present, conventional spinning laser system maintains a relatively fixed light window. However, low-light situations underwater, rotation of device causes some degree water fluctuation, which warps strip data that sensor receives about object’s surface. To solve this problem,...
