When the bias continues to increase to 0.25 V, the current decreases to zero due to the disappeared transmission peak. It is quite interesting that the insulator-like state can be maintained until the bias increases to 1.0 V. illusFtirgautiroen 4,(wa)esdheofwinsetthheebfaonlldow...
XRD, FTIR and NMR analyses revealed that a series of reactions occurred in the dehydrogenation of the composite. The prior interaction between LiH and Mg–B–N–H yielded intermediate LiBH4, which subsequently reacted with Mg(NH2)2 and LiH in molar ratio of 1:6:9 to form Li2Mg2(NH)3 ...
According to its FTIR spectrum, the absorption peaks of the B-H stretching modes of the BH4 group, the BH2 deformation bands, and N-H stretches can still be observed, but clearly decreased. Meanwhile, a new absorption peak of the B-N vibration is observed from 1700 cm−1 to 1750 cm...

Electrochemical methods, FTIR, 1H NMR and UV–vis analysis confirm that the resulting polymer is a copolymer rather than a blend or a composite of the respective homopolymers. Spectroelectrochemical analysis reveals that the copolymer film has distinct electrochromic properties from that of the BPL ...

The deconvolution of the normalized PL spectra shows that each PL spectrum is composed of four emission bands which peak at approximately the same energies of 2.1, 2.2 and 2.4 eV and whose intensities and widths depend upon the structure of the complexes. FTIR and ellipsometry are employed to ...
A possible calcium binding site in D1 protein: A fluorescence and FTIR study of the interaction between lanthanides and a synthetic peptide A peptide ranging from residue 229 to 240 of the D1 protein of Photosystem (PS) II was synthesized and lanthanides were used as candidates of calcium. Fl...

XRD and FTIR results show that the structure of LiCe(BH4)(3)Cl does not change before and after hydrogen absorption/desorption, indicating it plays the catalytic effect. The hydrogen desorption activation energy of Mg(NH2)(2)-2LiH doped with 0.03LiCe(BH4)(3)Cl was reduced by 37.5%. The ...
