A novel route was invented for utilizing thermal energy (at an elevated temperature of 110 ± 2 °C) to synthesize and crosslink gels from resorcinol formaldehyde without using catalysts or buffers. The outcome are identified by various techniques such as Fourier transform infrared, Raman spectroscopy, gravimetric analysis, X-ray diffraction, nano-scanning electron microscopy, energy-dispersive s...

A hybrid material reduced graphene oxide based organic nanocomposite was synthesized from graphite by modified Hummers method, which is further chemically to form (rGO) and with resorcinol through a solvothermal process oxide-resorcinol (rGO-R) obtained. The materials surface morphology structural compositions were studied X-ray diffraction (XRD) scanning electron microscope (SEM) their optical...

O estudo diz respeito ao comportamento oscilatório de resorcinol como substrato orgânico na reação de Belousov-Zhabotinsky (BZ) em presença de diferentes íons metálicos como catalisadores no meio aquoso ácido. Verifica-se que íons Mn como catalisador são mais reativos que íons Fe. Variando o meio aquoso ácido observa-se que as espécies protonadas são mais facilmente formadas em ácido sulfúrico ...

This study determined if any of four endodontic solutions would have a softening effect on resorcinol-formalin paste and if there were any differences in the solvent action between these solutions. Resorcinol, formalin, and zinc oxide were mixed and allowed to set for 30 days. The solutions tested were 0.9% sodium chloride, 5.25% sodium hypochlorite, chloroform, and Endosolv R. Seven samples pe...

Many members of the TetR family control the transcription of genes involved in multidrug resistance and pathogenicity. RolR (ResorcinolRegulator), the recently reported TetR-type regulator for aromatic catabolism from Corynebacterium glutamicum, distinguishes itself by low sequence similarities and different regulation from the previously known members of the TetR family. Here we report the cry...

The primary functions of root hairs are to increase the root surface area and to aid plants in water and nutrient uptake. However, some root hairs also have secretory functions and exude bioactive secondary metabolites. Sorghum (Sorghum bicolor) root hairs release a substantial amount of phenolic lipids including sorgoleone, a 3-pentadecatriene benzoquinone. The activity of the key enzymes invo...
