A partially biobased self-blowing and self-hardening polyurethane foam from glucose-based non-isocyanate polyurethanes (g-NIPU) was prepared by reaction of glucose with dimethyl carbonate hexamethylene diamine. However, these types generally require a high foaming temperature. In this paper, based on g-NIPU at room temperature using maleic acid as an initiator glutaraldehyde crosslinker. Water absorption, compression resistance, fire resistance were tested. Scanning electron microscopy (SEM)...
Ambient temperature self-blowing mimosa tannin-based non-isocyanate polyurethane (NIPU) rigid foam was produced, based on a formulation of resin. A citric acid and glutaraldehyde mixture served as blowing agent used to provide foaming energy cross-link the tannin-derived products synthesize NIPU foams. Series foams containing different amount were prepared. The reaction mechanism investigated by Fourier Trasform InfraRed (FT-IR), Matrix Assisted Laser Desorption Ionization (MALDI-TOF) mass...
One strategy for utilizing ammonia as an energy vector is to replace conventional hydrocarbons with hydrogen-enriched in existing or retrofitted combustors. However, the strong differential diffusion effect of hydrogen can significantly alter combustion properties and cause challenges combustor operability. Therefore, this numerical study performs a systematic investigation on fundamental ammonia/hydrogen fuel blends. The investigated span from initiation combustion, i.e., ignition,...
This study characterized and demonstrated the bistability (including both structural functional stability) of aerobic granular sludge (AGS) that was self-cultivated in a continuous flow membrane bioreactor for treatment real municipal wastewater (50 t/d). The results indicated elevated Ca2+ concentrations (28.44-34.21 mg/L) led to close proximity with extracellular polymeric substance (EPS) secreted by microorganisms (dominated denitrifying polyphosphate-accumulating organisms...
A highly diastereo‐ and enantioselective all‐carbon‐based Diels–Alder reaction of conjugated vinyl azides with β,γ‐unsaturated α‐keto esters amides was achieved. With C1‐symmetric imidazolidine‐pyrroloimidazolone pyridine as the tridentate ligand Cu(OTf)2 Lewis acid, diverse chiral fused spiro cyclohexenes an azido group containing three continuous stereogenic centers were obtained in good yields (up to 92% yield), excellent diastereoselectivities >20:1 dr) enantioselectivities 99% ee)....
Accurate quantification of heat release rate (HRR) profiles is useful for identifying important combustion processes in practical engines. This study aims to show whether the conventional HRR markers can still be used highly stretched premixed methane/air flames with and without hydrogen addition. The correlation formaldehyde-based molar concentrations, [H][CH2O] [OH][CH2O], numerically studied CH4/air CH4/H2/air flames. Two types are considered: spherically expanding flame (SEF) starting...
Statistically optimized near field acoustic holography (SONAH) is usually based on the assumption that all sources are one side of measurement plane whereas other source free. An extension SONAH procedure with an array pressure-velocity probes has recently been suggested. alternative method uses a double layer pressure transducers. Both methods make it possible to distinguish between two sides and thus suppress influence extraneous noise reflections coming from “wrong” side. This letter...
Ambient temperature self-blowing tannin–furanic foams have been prepared by substituting a great part—even majority—of furfuryl alcohol with humins, polyfuranic material derived from the acid treatment at high of fructose. Closed-cell were room and curing, while interconnected-cell 80 °C this being due to more vigorous evaporation solvent. These appear present similar characteristics as other based only on alcohol. A series tannin–humins–furfuryl oligomer structures defined indicating that...
