The Use of Natural Zeolite as A Catalyst for Esterification Reaction Between Glycerol and Oleic Acid
Reaktor, 2019 Natural zeolite in Indonesia generally divided into 2 types, which are mordernite and clinoptilolite. As far the use of zeolites is very limited. This experiment tries to use both types of natural zeolites to find out its work.

Natural zeolites: mineralogy and applications
European Journal of Mineralogy, 1991 After a brief description of the crystallochemical peculiarities of zeolites, which enable them to be used in many technological fields, the present and potential applications of natural zeolites are reviewed. The possibility of using Italian chabazite and phillipsite to reduce problems connected with nitrogen pollution is ...

Effect of characteristics of natural zeolites on their geopolymerization
Case Studies in Construction Materials, 2021 The properties of clinoptilolite-based geopolymers are investigated with a focus on the parameters affecting the reactivity of clinoptilolite in a geopolymer binder. A complete characterization of raw materials was carried out as well as a determination of the mineralogical composition, microstructure and mechanical properties of geopolymers.

Smart Electrospun Nanofibers for Controlled Oil‐Water Separation
Advanced Materials Interfaces, EarlyView.Stimuli‐responsive electrospun nanofibers are reviewed as advanced platforms for controlled oil/water separation. The effects of surface wettability, porous structure, and external stimuli, including pH, temperature, gas, and light, on separation performance are discussed.

Angewandte Chemie, EarlyView.Machine learning has digitalized heterogeneous catalysis from the top of the length scale downward: prediction at the atom and the material is now mature, yet the reactor and the process remain the open frontier. This critical review traces a decade of progress across the full catalytic value chain and asks where the next decade of impact must be won ...
