We report a facile nitrogenation/exfoliation process to prepare hybrid Ni-C-N nanosheets. These nanosheets are <2 nm thin, chemically stable, and metallically conductive. They serve as a robust catalyst for the hydrogen evolution reaction in 0.5 M H2SO4, or 1.0 M KOH or 1.0 M PBS (pH = 7). For example, they catalyze the hydrogen evolution reaction in 0.5 M(More)
A novel multifunctional peptide fluorescent chemosensor (DP-3) with a lysine backbone and double sides conjugated with histidine and dansyl groups has been designed and synthesized by solid phase synthesis. This chemosensor is a promising analytical tool for detecting Zn(2+), Cu(2+), and S(2-) based on different mechanisms in 100% aqueous solutions, and(More)
A novel metal-organic framework (MOF) was fabricated by spontaneous K(+)-induced supramolecular self-assembly with the embedded tripodal ligand units. When the 3D ligand was loaded onto Fe3O4@mSiO2 core-shell nanoparticles, it could effectively separate K(+) ions from a mixture of Na(+), K(+), Mg(2+), and Ca(2+) ions through nanoparticle-assisted MOF(More)
How to accurately predict electronic properties of a Columbic system with the electron density obtained from experiments such as X-ray crystallography is still an unresolved problem. The information-theoretic approach recently developed in the framework of density functional reactivity theory is one of the efforts to address the issue. In this work, using(More)
The synthesis of semiconducting nanoplates (NPs) with defined crystal phase is of particular interest, especially their intriguing properties related to the size, shape, and crystal phase. Herein, a liquid-state transformation process from hexagonal-phase CuS NPs is employed to fabricate the cubic-phase Cu2S NPs. The CuS NPs were converted into Cu2S NPs but(More)
Water-responsive shape-memory polymers (SMPs) are desirable for biomedical applications, but their limited shape recovery process is problematic. Herein, we demonstrate a shape-memory poly(vinyl alcohol) (SM-PVA) with programmable multistep shape recovery processes in water via a wettability contrast strategy. A hexamethyldisilazane (HMDS)-treated SiO2(More)
The first thiol-specific turn-on probe, BODIPY-TS, utilizing a thiosulfonate scaffold as the thiol recognition unit was reported. BODIPY-TS displays low toxicity, and features high sensitivity, fast response and quantitative reaction towards thiols. The structural novelty of BODIPY-TS would guide the development of novel thiol probes.
A novel peptide fluorescent chemosensor (H2L) with a lysine backbone and both -NH2 sites conjugated with cysteine and dansyl groups has been designed and synthesized by solid phase peptide synthesis with Fmoc chemistry. This chemosensor is a promising analytical tool for detecting Cd(2+) based on the photo-induced electron transfer (PET) effect by turn-on(More)
