Unusual product from the acid-catalyzed one-pot, multicomponent reaction of thiocarbohydrazide, aldehydes, and phenacyl bromides
(
Taylor & Francis
, 2017 , Article)
A one-pot, three-component protocol for the synthesis of novel five-membered thiazole ring bonded to two hydrazone motifs is described. The acid-catalyzed reaction of one equivalent of thiocarbohydrazide, two equivalents ...
Ac-conductivity analysis of the effects of partial dealumination and γ-irradiation on the electric features of HZSM-5
(
Elsevier
, 1996 , Article)
For illustrating such titled effects, analysis of the electric impedance, capacitance, and dielectric loss dependences on the frequency W (0.1–100 kHz) and temperature T (373–673 K) is correlated at 0.8 V for γ-irradiated ...
Evidence by ac-conductivity for the higher mobility of boron (over aluminium)-associated Brønsted sites in boron-modified HZSM-5
(
Elsevier
, 1996 , Article)
A correlation ac-conductivity analysis is performed at 102–105 Hz, 373–613 K and 0.8 V for characterizing the effect of increasing boron incorporation in HZSM-5 lattice on altered electric features in BZSM-5 samples of ...
Understanding the Origin of the Ultrahigh Rate Performance of a SiO2-Modified LiNi0.5Mn1.5O4 Cathode for Lithium-Ion Batteries
(
American Chemical Society
, 2019 , Article)
LiNi0.5Mn1.5O4 (LNMO) is one of the most promising cathode materials for next-generation lithium-ion batteries for rapid charging–discharging applications. The surfaces of LNMO samples are coated with different amounts ...
