Preparation and Properties of Natural Bamboo Fiber-Reinforced Recycled Aggregate Concrete.

To promote resource reuse and the green, low-carbon transformation of the construction industry, this study uses recycled aggregate from crushed waste concrete and natural bamboo fibers to formulate bamboo fiber-reinforced recycled-aggregate concrete. This study investigates the effects of natural bamboo fiber (NBF) content, NBF length, and the water-to-cement ratio on the performance of concrete through an orthogonal experiment to determine the optimal mixing proportions of NBF-reinforced concrete. Additionally, recycled aggregate completely replaced natural aggregate.

Magnetic core-shell FeO@CuO and FeO@CuO-Cu materials as catalysts for aerobic oxidation of benzylic alcohols assisted by TEMPO and -methylimidazole.

In this work, core-shell FeO@CuO and FeO@CuO-Cu nanomaterials for aerobic oxidation of benzylic alcohols are reported with 2,2,6,6-tetramethylpiperidine--oxyl (TEMPO) and -methylimidazole (NMI) as the co-catalysts. To anchor CuO nanoparticles around the magnetic particles under solvothermal conditions, the magnetic material FeO was modified by grafting a layer of l-lysine (l-Lys) to introduce -NH groups at the surface of the magnetic particles. With amine groups as the anchor, Cu(NO) was used to co-precipitate the desired CuO by using ethylene glycol as the reducing agent.

Diiron(ii) pentacarbonyl complexes as CO-releasing molecules: their synthesis, characterization, CO-releasing behaviour and biocompatibility.

Four diiron(ii) carbonyl complexes, [Fe2(μ-SR)3(CO)5X] (X- = Br-, I-; R = CH2CH3, CH2CH2CH3) were facilely synthesized by reacting [Fe(CO)4X2] with monothiolates. Their potential as carbon monoxide-releasing molecules (CORMs) was systematically investigated, revealing that their CO-releasing behaviour is highly solvent-dependent. Specifically, in dimethyl sulfoxide (DMSO), the CO-releasing kinetics were fast.
