The structure of traditional, linear phenol-formaldehyde (PF) resins and phenol-furfural (P-Furan) resins has been investigated by matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectroscopy. The structure of a variety of oligomers has been obtained and the structures present in each of the two types of resins related to the reagent used either formaldehyde or furfu...

Metal Binder Jetting emerged and it has been developing an additive manufacturing method. type, binder ratio, sintering process, atmosphere couldn’t be transparently determined due to its development stage. In this study, effect of temperature was investigated parts’ microstructure which manufactured by Additive Manufacturing. manufacturing, SS316L metal powder used as a raw material, ultraviol...

The Front Cover illustrates a green factory where furfuryl alcohol is happily converted to high valued angelica lactones and levulinic acid as it passes through the NbOPO4 “catalyst gate” while sadly unspoiled on Nb2O5 in rainy wet day. In their Research Article, M. A. Fraga co-workers show that hydrolysis occurs Brønsted sites strength critical process. Mixtures of organic solvent water hinder...

The aim of this article is to test the properties of foundry moulding sands with a new bicomponent organic binder. The new binder is the composition of phenol-furfuryl resin, commonly used in foundry practice and biodegradable material – polycaprolactone. The paper presents the research of strength properties, thermal destruction and thermal deformation of moulding sands with a new bicomponent ...

In this work the photocatalytic (PC) and photoelectrocatalytic (PEC) reforming of furfuryl alcohol (FA) under environmental friendly conditions was investigated. Both H2 evolution partial oxidation to furfuraldehyde were followed. For first time TiO2 based photocatalysts studied activity home prepared compared with that commercial ones both UVA simulated solar irradiation. PEC tests performed b...

The effect of nickel precursors and the temperature annealing to obtain intermetallic Ni3Sn2 alloy catalysts on its activity selectivity in selective hydrogenation biomass-derived furfural (FFald) were investigated. Two types (c.a., i) metal (Ni°) derived from Raney®nickel ii) ion (Ni2+) chloride) employed as starting materials via hydrothermal at 423 K for 24 h followed by reduction with H2 el...
