| 1 | Low-overpotential electrochemical ammonia synthesis using BiOCl-modified 2D titanium carbide MXene显示文摘Electrochemical synthesis of ammonia has the advantages of low energy consumption and promising environmental protection,as compared to the traditional Haber-Bosch process.However,the commercial utilization of this novel system is limited by the low Faradaic efficiency,poor ammonia yield and high overpotential due to the strong NN bond and the dominant competing reaction of hydrogen evolution reaction(HER).Herein,a BiOCl-modified two-dimensional(2D)titanium carbide MXenes nanocomposite(BiOCl@Ti_(3)C_(2)T_(x))is proposed as a promising electrocatalyst for ambient nitrogen(N_(2))reduction reaction with excellent catalytic performance and superior long-term stability at low overpotential.In 0.1 mol/L HCl,this catalyst attains a high Faradic efficiency of 11.98%and a NH_(3)yield of 4.06μg h^(-1)cm^(-2)at-0.10 V(vs.RHE),benefiting from its strong interaction of Bi 6p band with the N 2p orbitals,combined with its large specific surface area and the facile electron transfer. | Yu Wang Munkhbayar Batmunkh Hui Mao Hui Li Baohua Jia Shuyao Wu Daliang Liu Ximing Song Ying Sun Tianyi Ma | 2022 | Chinese Chemical Letters2022，33，1： | 2 |
| 2 | High-efficiency Extraction of Bitumen from Oil Sands Using Mixture of Ionic Liquid [Emim][BF_(4)] and Dichloromethane显示文摘An ionic liquid(IL),1-ethyl-3-methyl imidazolium tetrafluoroborate([Emim][BF_(4)]),was used to enhance bitumen recovery from oil sands by dichloromethane solvent extraction.A multiphase system could be formed by simply mixing the components at ambient temperature,consisting of sands and clays,mixtures of ionic liquid and dichloromethane,and concentrated bitumen layer.The results demonstrated that[Emim][BF_(4)]increased the bitumen recovery up to 92%.Much less clay fines were found in the recovered bitumen than those formed by using dichloromethane solvent extraction alone,and the dichloromethane residue was not detected in the spent sands.We proposed that[Emim][BF_(4)]had an ability to reduce the adhesion of bitumen to sand,resulting in an improved separation efficiency.Furthermore,[Emim][BF_(4)]could facilitate the transfer of the extracted bitumen to the surface interface,and then the bitumen was auto-partitioned to a separate immiscible phase for ease of harvesting.This technology circumvented the issue of high consumption of distillation energy due to separation of bitumen phase and low boiling point of dichloromethane.[Emim][BF_(4)]and dichloromethane could be readily recycled through the system and used repeatedly.After ten cycles,the bitumen recovery remained above 88%.Initial scale-up work suggested that this approach would form the basis for a viable large-scale process. | Sun Yinlu Sun Yizhuo Jia Yushan Yuan Wei Song Ximing | 2021 | China Petroleum Processing & Petrochemical Technology2021，23，2： | 2 |
| 3 | DGP1,a drought-induced guard cell-specific promoter and its function analysis in tobacco plants显示文摘The genetic regulation of stomatal movement mainly depends on an efficient control system of gene expression, and guard cell-specific promoter is becoming the best choice. Here we combined the dehydration responsive element (DRE) with guard cell specific element (GCSE) to construct a novel promoter, DGP1. Histochemical assays in transgenic tobacco carrying β -glucuronidase (gus) gene fused to DGP1 demonstrated that GUS activity was found to be highly inducible by drought treatment and specifically restricted to guard cells. No GUS activity was detected in roots, stems or flowers after treatment. Further quantitative analysis showed that GUS activity in the epidermal strips was apparently induced by dehydration and dramatically increased with the elongation of treatment. The GUS activity after 8 h treatment was 179 times that of those without treatment. Although GUS activity in roots, stems or mesophyll increased after treatment, no great changes were observed. These results suggested that DGP1 could drive target gene expressed in guard cells when plant is subjected to drought stress. And this gets us prepared to control opening and closing of stomata through plant gene engineering. | LI Jun GONG Ximing LIN Huiqiong SONG Quanbo CHEN Jia WANG Xuechen | 2005 | Science China(Life Sciences)2005，48，2： | 1 |
