Hypochlorous acid (HOCl), as a highly potent oxidant, is well-known key "killer" for pathogens in the innate immune system. Recently, mounting evidence indicates that intracellular HOCl plays additional important roles regulating inflammation and cellular apoptosis. However, organelle(s) involved distribution of remain unknown, causing difficulty to fully exploit its biological functions signaling pathways various diseases. One main reasons lies lack effective chemical tools directly detect...
Abstract At present, the technological groundwork of atomically thin two-dimensional (2D) hetero-layered structures realized by successive film epitaxial growth is in principle constrained lattice matching prerequisite as well low yield and expensive production. Here, we artificially coordinate ultrathin 2D metal chalcogenides via a highly scalable self-surface charge exfoliation electrostatic coupling approach. Specifically, bulk are spontaneously exfoliated into layers...
Abstract Molecular rotors have played an important role in recent materials chemistry. Although several studies on functional containing molecular been reported for fluorescence sensing, this concept has yet to be realized two-dimensional (2D) materials. Here we report the preparation of all-carbon, π-conjugated 2D porous organic nanosheets, named NUS-24, which contain flexible tetraphenylethylene (TPE) units as rotors. NUS-24 nanosheets exhibit high stability, large lateral size, and...
Deuterium labeling is of great value in organic synthesis and the pharmaceutical industry. However, state-of-the-art C-H/C-D exchange using noble metal catalysts or strong bases/acids suffers from poor functional group tolerances, selectivity lack scope for generating molecular complexity. Herein, we demonstrate deuteration halides heavy water as reagent porous CdSe nanosheets catalyst. The mechanism involves generation highly active carbon deuterium radicals via photoinduced electron...
Doping the perovskite layer with a small amount of alkali metal ions can enhance photovoltaic efficiency solar cells.
Perovskite solar cells using highly pure PbI<sub>2</sub>exhibit an efficiency higher than that with low purity PbI<sub>2</sub>by 30–40%.
Abstract Although multiphoton-pumped lasing from a solution of chromophores is important in the emerging fields nonlinear optofluidics and bio-photonics, conventionally used organic dyes are often rendered unsuitable because relatively small multiphoton absorption cross-sections low photostability. Here, we demonstrate highly photostable, ultralow-threshold biexcitonic colloidal CdSe/CdS nanoplatelets within cuvette-based Fabry–Pérot optical resonator. We find that surprisingly exhibit an...
A spontaneous growth and assembly of non-layered Ni–B<sub>i</sub> into 2D nanosheets onto a graphene support, which demonstrate superior photo electro catalytic performance over pure aggregates.
A series of novel pyrazine–triphenylamine fused structures have been synthesized and the nonlinear optical absorptions these compounds can be overturned by protonation.
The presence of excess PbI<sub>2</sub>can affect the structure perovskites and photovoltaic performance perovskite solar cells. Increased open-circuit voltage could be achieved by introducing proper PbI<sub>2</sub>. However, shorter carrier lifetime increased recombination resistance were observed when an PbI<sub>2</sub>was used.
Planar heterojunction perovskite solar cells with MA<sub>1−x</sub>FA<sub>x</sub>PbI<sub>3−y</sub>Cl<sub>y</sub> can exhibit a high power conversion efficiency (PCE) of up to 18.14%.
Nitrophenols are important nitroaromatic compounds, both environmental pollutants and dangerous explosives, posing a devastating danger pollution threat to humans. It is vital detect efficiently trace nitrophenols in the environment. In this contribution, series of fully flexible cyclotriphosphazene-based COFs (FFCP COFs: HDADE, HBAPB, HBPDA), prepared with knot linkers different lengths, were used for sensing 2,4,6-trinitrophenol (TNP) p-nitrophenol (p-NP) real time excellent sensitivity...
KPFM study of various structures with a perovskite layer indicates unbalanced charge-carrier transport and extraction.
We report the synthesis of a perylene derivative (perylene tetracarboxylic di(propyl imidazole), abbreviated as PDI) that is coordinated with Co(II) ions to form coordination polymer [PDI–Co(Cl)2(H2O)2]n (abbreviated PDI-Co). The PDI-Co complex combines photoactivity dye electrocatalytic activity "Co(II)" center for photoelectrochemical hydrogen evolution reaction (HER). To improve charge transfer interactions, immobilized on reduced graphene oxide (rGO) via noncovalent interactions...
Photosensitizer is the key element in photodynamic therapy to generate singlet oxygen exert cytotoxic effects on cancerous or diseased tissues. Conventional organic photosensitizers generally have poor photostability. Nano-photosensitizers display high resistance photodegradation. However, toxicity of quantum dots and requirement UV light activation for ZnO TiO2 limit their practical applications. Here, we developed Au nanorod (Au NR)/ZnO core–shell nanostructures that integrate nanorods...
Biochemical sensors have found widespread applications in the fields of health and environment. As number biochemical continues to increase, their energy supply has emerged as a challenge. Self-powered based on triboelectric generators (TENGs) offer promising solution this However, current self-powered for situ detection liquid samples either suffer from low output signals, resulting insufficient sensitivity, or require relatively large sample volumes. To address these challenges, work...
