Lianchen等将脱矿牙釉质样品浸在10000ppm的PAMAM-COOH溶液中30分钟,然后在钙磷含或不含氟的溶液中20小时。SEM和FTIR表明,诱导的HAP晶体具有类似自然完好的牙釉质的结构和形态。因此,PAMAM-COOH可以诱导HAP晶体,成为脱矿釉质的有机模板。在此,晶体的生长是直接发生的,但持续时间是...
The attenuated total reflection (ATR) Fourier transform infrared (FTIR) spectra were obtained using a Thermo scientific Nicolet iS10 spectrometer. The Brunauer-Emmett-Teller (BET) surface areas of the as-prepared powder samples were measured using a Quantachrome ChemBET TPR/TPD analyzer equipped with...
Combined with the analysis of in situ ATR-FTIR spectroscopy technology, the photocatalytic reduction mechanism of Cr(VI) is confirmed as a proton coupled electron transfer process. The improved photocatalytic activity of the Sn4+ self-doped SnS can be attributed to the enhanced photoabsorption ...

New compounds of bimetallic trimethyltin(IV) germapropionates have been synthesized and characterized by elemental analyses, FTIR, and multinuclear nmr (1H,13C,119Sn) spectroscopies. These compounds show fourcoordinated structure in solution and pentacoordinated structure in solid state. The crystal ...
