The recent strategies in preparation of cellulose nanocrystals (CNCs) and nanofibrils (CNFs) were described. CNCs CNFs are two types nanocelluloses (NCs), they possess various superior properties, such as large specific surface area, high tensile strength stiffness, low density, thermal expansion coefficient. Due to applications biomedical engineering, food, sensor, packaging, so on, there many studies conducted on CNFs. In this review, methods summarized, including mechanical, chemical,...
In the current work, a green and recyclable FeCl3-catalyzed deep eutectic solvent system (F-DES) was invented to fabricate cellulose nanocrystals (CNCs) with high yield excellent thermal stability. It found that optimum composition of composed oxalic acid dihydrate (Oxd), choline chloride (ChCl), FeCl3·6H2O in mass ratio 4:1:0.2 (corresponding molar 4.43:1:0.1). Results showed CNCs diameter range 5–20 nm length 50–300 could be isolated from bleached eucalyptus kraft pulp (BEKP) at (over 90%...
As a weak tricarboxylic acid, citric acid (CA) has been proposed for the preparation of cellulose nanocrystals (CNCs) due to its innocuous and easily recyclable nature. However, yield obtained CNCs is normally below 30% by CA hydrolysis acidity CA. In this work, FeCl3 was discovered as powerful catalyst enhance efficiency green highly efficient carboxylic thermostable CNCs. The maximum 80.28% could be achieved via FeCl3-catalyzed under optimal condition 85 wt % aqueous solution 0.02 mmol...
Polymer nanoparticles with low curvature, especially two-dimensional (2D) soft materials, are rich in functions and outstanding properties have received extensive attention. Crystallization-driven self-assembly (CDSA) of linear semicrystalline block copolymers is currently a common method constructing 2D platelets uniform size. Although accompanied by high controllability, this CDSA usually inevitably requires longer aging time lower assembly concentration, limiting the large-scale...
This study investigated the effectiveness and prospect of applying virtual simulation operation (VSO) as a novel teaching tool in clinical skill courses.A comparative test survey on effect VSO was conducted with course course. The group students received offline courses combined online practice. In contrast, control instructional video review. two groups were assessed using Chinese medical school medicine professional level questionnaire survey.The scored significantly higher than skills...
The tandem iminium cyclization and Smiles rearrangement of pyridinyloxyacetaldehyde 1 a primary amine generated novel pyrido[2,3-e]pyrrolo[1,2-a]pyrazine scaffold. TFA was discovered to be an efficient catalyst in the reactions with aromatic amines, whereas TiCl4 found superior case aliphatic amines. This methodology proved preparation library diversified derivatives.
An efficient and practical method has been developed for the synthesis of trans-4,5-disubstituted 3-carboxy-4,5-dihydropyrroles via an intramolecular iminium ion cyclization reaction readily accessible Baylis-Hillman derivatives aldehydes in moderate to high yield. These new dihydropyrroles could be easily converted pyrroles or pyrrolidines.
