DOI: 10.1016/j.apsusc.2020.145398
Abstract: Abstract Zeolite catalysts (ZSM-5) were synthesized using different ratios of structure directing agents (SDA) and Si/Al, and the synthesized ZSM-5 samples were used in the endothermic decomposition reaction of exo-tetrahydrodicyclopentadiene (exo-THDCP). The ZSM-5 synthesized with… read more here.

DOI: 10.3390/biomimetics7020054
Abstract: The aim of this study was to investigate the effects of two process-directing agents (polyaspartic acid and osteopontin) used in a polymer-induced liquid-precursor (PILP) process on the remineralization of bacteria-induced enamel demineralization. Enamel demineralization lesions… read more here.
