γ-Valerolactone (GVL) is considered a very interesting green, bio-based platform chemical with high application potential. We here describe research activities on the one-pot catalytic synthesis of GVL from C6-sugar sources (D-glucose, D-fructose, sucrose and cellulose) using an acid catalyst in combination hydrogenation (Ru/C) either molecular hydrogen or formic as donor. When acid, highest yield (52 mol%) was obtained at 180 °C, 16 h reaction time D-fructose source. The major by-products...
A simple and fast method to prepare robust superhydrophobic octadecylphosphonic acid (ODPA) coating on oxidized copper mesh for self-cleaning oil/water separation is reported here. The substrate of the was first by immersion in an aqueous solution 1.0 M NaOH 0.05 K2S2O8 at room temperature 30 min, which then covered with micro- nanoscale Cu(OH)2 surface. Subsequently, immersed 2 × 10(-4) acid/tetrahydrofuran (ODPA/THF) solution, ODPA formed oxidised mesh. formation process takes place...
Solar energy, as a clean and renewable energy source, holds significant promise for addressing water shortages. Utilizing solar evaporation is seen an effective solution in this regard. While many existing interfacial photothermal systems rely on nanoparticles or graphene support materials, study introduced polydopamine (PDA) material due to its environmental friendliness excellent photon absorption characteristics that closely match the spectrum. Polystyrene (PS) was also porous structure...
A novel ultralight superhydrophobic-superoleophilic hybrid Carbon Nanotubes (CNTs) film with double-layer structures is fabricated by using vacuum filtration method. The CNTs can separate various surfactant-stabilized water-in-oil emulsions a separation efficiency higher than 99.3%. Moreover, the films be regenerated through simple and rapid combustion process within 2 s. In addition, still retains good hydrophobic properties under conditions of physical abrasion, strong acidic alkaline...
A series of epoxy vitrimers (EVs) with enhanced glass transition temperatures (Tgs) were synthesized by curing resin E51 different ratios phthalic anhydride and sebacic acid as agents, 1,5,7-triazabicyclic [4.4.0] dece-5-ene a transesterification catalyst, their dynamics, rheological properties, mechanical thermal stability comprehensively investigated. By adjusting the molar ratio to carboxylic in agent, Tgs EVs increased from 79 143 °C increase content. In particular, material EV-5.5 high...
Shape memory polymers (SMPs) have been applied in aerospace engineering as deployable space structures. In this work, the coupled finite element method (FEM) was established based on generalized Maxwell model and time–temperature equivalence principle (TTEP). The thermodynamic behavior shape effects of a single-arm deployment structure (F-DS) four-arm SMPs were analyzed using FEM. Good consistency obtained between experimental data simulation for tensile S-DS recovery forces, verifying that...
With the deepening of energy structure transformation, new sources such as photovoltaics and wind power are important means to achieve carbon neutrality in future. In order solve instability problem their use, research on electrochemical storage systems has become a key aspect. addition, lithium-ion batteries play an role electronic devices, but lower theoretical specific capacity makes it difficult meet needs large devices. Lithium-sulfur have density (2600 Wh•kg<sup>-1</sup>) (1675...
