Temperature is one of the controlling factors determining chemical structure char. We employed advanced solid-state 13C NMR techniques to characterize maple wood and its chars produced under N2 at temperatures from 300 700 °C. Our results indicated that °C char was primarily composed residues biopolymers such as lignin cellulose. Carbohydrates are completely lost for prepared 350 At 400 °C, most ligno-cellulosic features consisted predominantly aromatic structures. By 500 sp3-hybridized...
Synthesized siderite was used to remove As(III) and As(V) from water solutions under anoxic conditions oxic conditions. Results showed that As adsorption on synthetic around 10 mg/g calculated with Langmuir isotherm. However, the ranged between 115 121 mg/g, which 11 times higher than It found 75% transformed into goethite during adsorption. had lower capacity conditions, although its a little suggested coexistence of bimineral mineral transformation probably contributed robust extended...
A novel composite absorbent was developed based on dissolved cellulose fibers (as matrix) reinforced with microfibrillated (MFC). Both and were functionally modified using an organic solvent-free approach to introduce carboxyl groups onto the surface of MFC. To further enhance adsorption capacity, nanosized CaCO3 added as a pore forming agent during formation cellulose/MFC (CMFC) composites removed in acidic conditions afterward. The structure morphology as-synthesized adsorbents identified...
Manganese oxide (MnOx) is a considerable candidate for supercapacitor electrode materials owing to its large theoretical capacitance and low price, but performance generally limited by unsatisfactory cycle poor conductivity. Herein, Mn2O3@MnO2 composite nanofibers have been prepared via electrospinning hydrothermal methods. Adjusting the KMnO4 precursor concentration during process, core–shell with variable compositional ratios of MnO2 Mn2O3 obtained. The hierarchically structure synergistic...
Abstract Deep eutectic solvents (DESs) have been considered as novel and economic alternatives to traditional lubricants because of their similar physicochemical performance. In this study, choline chloride (ChCl) DESs were successfully synthesized via hydrogen-bonding networks urea thiourea the hydrogen bond donors (HBDs). The as-synthesized ChCl-urea ChCl-thiourea had excellent thermal stability displayed good lubrication between steel/steel tribo-pairs. friction coefficient wear rate DES...
Abstract Nanofibers prepared by electrospinning technology possess large specific surface area and adjustable fiber diameter. Zein is a hydrophobic plant protein that can interact with pollutants in the air. In this work, using polyvinyl alcohol (PVA) as auxiliary spinning polymer, zein based nanofiber materials are for air filtration varying zein/PVA ratio well alcoholysis degree. With increase of content, diameter nanofibers decreases gradually, PVA low degree exhibit better...

Polymers PE-1 and PE-2 attained thermal decomposition temperatures 305 223 °C glass transition 113 108 °C, exhibited only negligible decay SHG signal baked at 85 over hundreds hours, respectively. The coefficients poled films from were 26.3 35.8 pm/V, These results indicated that this class can be used preparation electro-optic devices.
Oil/water separation is a field of high significance as it might efficiently resolve the contamination industrial oily wastewater and other oil/water pollution. In this paper, an environmentally-friendly hydrophobic aerogel with porosity low density was successfully synthesized renewable pomelo peels (PPs) precursors. Typically, series sponge aerogels (HPSA-0, HPSA-1 HPSA-2) were facilely prepared via high-speed dispersion, freeze-drying silanization methyltrimethoxysilane. Indeed, physical...
Thermally activated delayed fluorescent (TADF) emitters have received great attention in organic light-emitting diodes and laser because of high exciton utilization efficiency low optical loss caused by triplets. However, the direct observation lasing emission from nondoped TADF microcrystals has yet to be reported. Here, we demonstrated a three-color (green, yellow, red) microlaser three with well-controlled geometries. The temperature-dependent dynamic analyses testify that regenerated...
