Reversible pH‐Responsive Surface: From Superhydrophobicity to Superhydrophilicity

Advanced Materials (2005)

Xi Yu Zhongqiang Wang Yang Jiang Fei Shi Xianfeng Zhang

A pH-responsive surface has been fabricated by chemisorption of HS(CH2)9CH3 and HS(CH2)10COOH in an appropriate ratio onto a fractal-like gold structure. The surface exhibits superhydrophobicity in an acidic environment and superhydrophilicity under basic conditions. The Figure (right, top) shows an acid droplet on the gold surface, while the image below it shows a base droplet.

Pyrolysis characteristics and kinetics of Prunus avium L. leaves using thermogravimetric analysis

BioResources (2023)

Quan Li Fangzhi Zhu Fei Shi Nan Zhang Huimin Zhang

Differences in the pyrolysis characteristics of leaves of sweet cherry tree (Prunus avium L.) under rain-shelter cultivation (RS) or under open-field cultivation (CK) were analysed using thermogravimetry (TG), derivative thermogravimetry (DTG), and differential scanning calorimetry (DSC) at three heating rates of 10, 20, and 30 °C·min-1. There were two obvious mass loss peaks at 280 °C and 330 °C, which were manifested by the slow pyrolysis of hemicellulose in the low temperature region and the rapid pyrolysis of cellulose in the high temperature region, respectively. The curve in the pyrolysis range after 440 °C was stable, and the mass change corresponded to the pyrolysis of a small amount of macromolecular organic extracts and inorganic salts. When the temperature reached 600 °C, approximately 69% and 73% of the CK and RS leaves were thermally destroyed, respectively. The Coats-Redfern method was used for kinetic calculations to obtain an activation energy of 29.8 to 36.1 kJ·mol-1 in the first-order pyrolysis kinetics stage. The second-order pyrolysis kinetics stage can fit the pyrolysis process well. A significant difference was observed in the pyrolysis characteristics or the kinetics between CK and RS, which were related to the heating rate and the hemicellulose content, cellulose content, and lignin ratio in each sample.

New BN/SiOC aerogel composites fabricated by the sol-gel method with excellent thermal insulation performance at high temperature

Materials & Design (2019)

Haixia Yang Chunming Li Xiandong Yue Jianchun Huo Feng Ye

Although pure silicon oxycarbide (SiOC) aerogels have unique properties of low density and high temperature resistance, they are still difficult to apply at a large scale due to brittleness. To overcome this drawback, a strong boron nitride/silicon oxycarbide (BN/SiOC) aerogel composite with high-temperature resistance and thermal insulation was prepared by the sol-gel method and pyrolysis of the precursor aerogel. The microstructural, mechanical and thermal insulation properties of the composites were investigated, and the effect of the BN content on the microstructure and properties was also clarified. The results indicate that the obtained mesoporous composites exhibit low thermal conductivity (0.04–0.20 Wm−1 K−1) and high-temperature resistance (∼1300 °C). As the BN content increased from 0 to 15 vol %, the compressive strength of the composites increased from 2.2 to 20.3 MPa. The obtained composites exhibit considerable promise in high-temperature thermal insulation applications.

Experimental Investigation of Biomass Slag Deposit on the Surface of Super-Heaters

Advanced materials research (2013)

Fei Shi Lu An Bao Min Sun

Growing attention had been drawn to the use of biomass as fuel for electricity generation in China. However, as a fairly new imported technology in localization, it had met serious problems with slagging and fouling of the super-heaters. The slag deposit on the first super-heaters in a biomass boiler was characterized by XRD, SEM-EDS and XRF to make clear the reason for the slag deposit. According to the results, alkali metal such as K, Na and Ca were predominant in the slag deposit. NaCl and KCl in the form of halite and sylvite were confirmed by XRD.
