Rosin-derived porous microspheres with robust selective cationic dye adsorption
Adsorption Dyes Methylene blue Crystal violet Rosin Polymer microspheres
2023/12/15
The utilization of rosin to fabricate functional polymers has attracted great attention due to its unique structure and property. Herein, we prepared a new type of carboxyl-containing cross-linked ros...
Highly selective production of renewable p-xylene from bio-based2,5-dimethylfuran and ethylene over Al-modified H-Beta zeolites
p-xylene ethylene Al-modified H-Beta zeolites
2023/6/19
Highly selective synthesis of renewable p-xylene (PX) from bio-based 2,5-dimethylfuran (DMF) and ethylene was successfully realized on H-Beta zeolite catalysts with further Al-modifications. The influ...

Efficient Selective Identity-Based Encryption Without Random Oracles
Random Oracles Identity-Based Encryption
2015/8/5
We construct two efficient Identity Based Encryption (IBE) systems that are selective identity secure without the random oracle model Selective identity secure IBE is a slightly weaker security model ...
Effects of crystallinity of ZSM-5 zeolite on para-selective tert-butylation of ethylbenzene（图）
ZSM-5, Fluoride medium p-selectivity Ethylbenzene Tert-butylation, Zeolite
2013/9/27
Highly crystalline ZSM-5 zeolites are important for para-selective alkylation of alkyl aromatics, because they carry few external acid sites for isomerization of p-dialkyl products. Such zeolites (Si/...
Solvent-Free Selective Cross-Aldol Condensation of Ketones with Aromatic Aldehydes Efficiently Catalyzed by a Reusable Supported Acidic Ionic Liquid（图）
