Abstract: The sustainable production of polymers and materials derived from renewable feedstocks such as biomass is vital to addressing the current climate and environmental challenges. In particular, finding a replacement for current widely used curable resins containing undesired components with both health and environmental issues, such as bisphenol-A and styrene, is of great interest and vital for a sustainable society. In this work, we disclose the preparation and fabrication of an all-biobased curable resin. The devised resin consists of a polyester component based on fumaric acid, itaconic acid, 2,5-furandicarboxylic acid, 1,4-butanediol, and reactive diluents acting as both solvents and viscosity enhancers. Importantly, the complete process was performed solvent-free, thus promoting its industrial applications. The cured biobased resin demonstrates very good thermal properties (stable up to 415°C), the ability to resist deformation based on the high Young's modulus of ~775 MPa, and chem. resistance based on the swelling index and gel content. We envision the disclosed biobased resin having tailorable properties suitable for industrial applications.

Abstract: The electrocatalytic hydrogenation of 5-hydroxymethylfurfural (HMF) to 2,5-bis(hydroxymethyl)furan (BHMF) is an alternative to conventional heterogeneous catalysis with H2 at high temperatures and pressures. Although Ag is the most representative electrocatalyst, it works only under limited conditions. This study synthesizes highly porous dendritic Bi, Sn, and BiSn electrocatalysts using an in situ generated hydrogen bubble template. Density functional theory computations on the adsorption energy and elementary hydrogenation reaction steps of HMF predict the superiority of Bi to Sn and the intermediate behavior of BiSn between Bi and Sn. The dendritic BiSn catalyst generates a current density of ～144 mA cm?2 at a faradaic efficiency (FE) of ～100% for BHMF production at pH ～ 7 (corresponding to the BHMF production rate of ～2.7 mmol h?1 cm?2) in prolonged electrolysis. Considering the material cost (

YieldReaction ConditionsOperation in experiment
72 %Spectr. at 100℃; for 10 h; 1.8 g of sucrose,0.271 g of GeCl4, 0.091 g of BBr3, and 20 mL of n-propanol were added to 50 mL of a polyTetrafluoroethylene-lined stainless steel reactor,Heated to l00 ° C,The reaction was carried out at that temperature for 10 h. Filtration,To remove unreacted sucrose and other insoluble impurities,The solvent was removed by rotary evaporation,2 mL H20 was added and the organic phase was extracted with methyl isobutyl ketone,The resulting organic phase was rotary evaporated to a high purity furan derivative,The isolated yield was 83percent. The qualitative analysis of the reaction products was carried out by gas chromatography-mass spectrometry (GC-MS)And with the standard material (HMF,5-propoxymethylfurfural and propyl propionate) in gas chromatography (GC) were compared and confirmed. Quantitative analysis of the yield distribution of different furan derivatives was confirmed by 1H NMR,The product distribution results are:5-propoxymethylfurfural was 72percent, HMF was 9percentPropyl propionate was 19percent
