Construction of SnO buffer layer and analysis of its interface modification for Li and LiAlGe(PO) in solid-state batteries.

SnO layer between LiAlGe(PO) (LAGP) and lithium anode was prepared through simple scratch-coating process to improve interface properties. The physical phase, morphology, and electrochemical properties of Li/SnO/LAGP structure were characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, and electrochemical analytical methods. It was found that SnO layer effectively improved the interface stability of LAGP and lithium anode.

Nitrogen-rich energetic monoanionic salts of 3,4-bis(1H-5-tetrazolyl)furoxan.

3,4-Bis(1H-5-tetrazolyl)furoxan (H(2)BTF, 2) and its monoanionic salts that contain nitrogen-rich cations were readily synthesized and fully characterized by multinuclear NMR ((1)H, (13)C) and IR spectroscopy, differential scanning calorimetry (DSC), and elemental analyses. Hydrazinium (3) and 4-amino-1,2,4-triazolium (7) salts crystallized in the monoclinic space group P2(1)/n and have calculated densities of 1.820 and 1.

Energetic salts based on dipicrylamine and its amino derivative.

Energetic salts based on dipicrylamine and its amino derivative were synthesized. All salts were fully characterized by multinuclear NMR spectroscopy ((1)H, (13)C), vibrational spectroscopy (IR), and elemental analysis. Ethylenediammonium di-DPA (DPA=dipicrylamine) and 1,3-diaminoguanidinium DPA were further confirmed by single-crystal X-ray diffraction.

A metal-free aerobic oxidation of nitrotoluenes catalyzed by N,N',N″-trihydroxyisocyanuric acid (THICA) and a novel approach to the catalyst.

A metal-free catalytic system with N,N',N″-trihydroxyisocyanuric acid (THICA) as the catalyst for the oxidation of nitrotoluenes is introduced, and a novel Pd-free approach for the synthesis of THICA was developed. In a solution of acetic acid, THICA and concentrated nitric acid, nitrotoluenes especially polynitrotoluenes such as 2,4,6-trinitrotoluene (TNT), were converted into the desired carboxylic acids under 0.2 MPa of O(2) at 100°C with yields up to 99%.
