DNA from salmon testes was solubilised in two bio-based ionic liquids up to 3.5% w/w in 6 h. No structural degradation of the molecule was observed for the sample solubilised in choline-indole-3-acetate (chol-IAA). However, the molecule was found to be denatured in choline-indole-3-butyrate (chol-IBA). The structural and chemical stability of the DNA molecules after six months of storage in the...

Recently, the use of fibers has become an attractive option to be implemented as reinforcement in Asphalt Concrete (AC) mixtures. Nonetheless, few studies have been carried out evaluate recyclability potential AC mixtures incorporating fibers. In this study, reinforcing effect polyacrylonitrile (PAN) is investigated. Air voids, Marshall stability, indirect tensile strength (ITS), moisture sensi...

Sulfonated polystyrene/montmorillonite nanocomposite (OMMT/PS-SO3H) was prepared and used as a novel, efficient and inexpensive heterogeneous acid catalyst in the one-pot reaction three-component Mannich reaction of ketones, aromatic aldehydes and amines under solvent-free conditions. The catalyst was characterized by XRD, SEM, TG, BET and FT-IR techniques. This method has advantages...

A novel Geotrichum candidum aldehyde dehydrogenase (GcALDH) effectively oxidized aldehydes to carboxylic acids under mild conditions. Nonetheless, the free form of GcALDH still had a limitation in stability and recyclability. Herein, overcome these limitations, this study achieved immobilization by organic-inorganic nanocrystal formation. The exhibited 261 ± 40 % activity comparing enzyme. It a...

The first effective organopolymerization of the biorenewable "non-polymerizable" γ-butyrolactone (γ-BL) to a high-molecular-weight metal-free recyclable polyester is reported. The superbase tert-Bu-P4 is found to directly initiate this polymerization through deprotonation of γ-BL to generate reactive enolate species. When combined with a suitable alcohol, the tert-Bu-P4 -based system rapidly co...

Herein we report for the first time fabrication of reverse bumpy ball (RBB)-type-nanoreactor-based flexible peroxidase-mimic membrane reactors (MRs). The RBB-type nanoreactors with gold nanoparticles embedded in the inner walls of carbon shells were loaded on nylon membranes through a facile filtration approach. The as-prepared flexible catalytic membrane was studied as a peroxidase-mimic MR. I...
