| 1 | Mechanisms and field test of solution mining by self-resonating cavitating water jets显示文摘Rapid solution mining is the key to cavern construction in salt formations. Rapid solution mining technology with self-resonating cavitating water jets is described in this paper. It can generate three main physical effects: helical flow dissolution, self-resonating cavitating jet erosion, and ultrasonic waves. A self-resonating cavitating nozzle was also designed with the principles based on theory of fluid transients and hydro-acoustics. Under ambient pressure, the experimental results show that the impulse amplitude of pressure reaches a peak at a standoff distance of 5-13 times the nozzle outlet diameter and the cutting ability of self-resonating cavitating jets is twice that of conventional jets under the same conditions. Compared with the conventional mining method, the field test indicates that rapid solution mining technology with self-resonating cavitating jets can speed the construction by more than 2 times at the pocket stage of cavern development. | Song Xianzhi Li Gensheng Yuan Jinping Tian Zhonglan Shen Ruichen Yuan Guangjie Huang Zhongwei | 2010 | Petroleum Science2010，7，3： | 5 |
| 2 | Key technologies and practice for gas field storage facility construction of complex geological conditions in China显示文摘In view of complex geological characteristics and alternating loading conditions associated with cyclic large amount of gas injection and withdrawal in underground gas storage(UGS) of China, a series of key gas storage construction technologies were established, mainly including UGS site selection and evaluation, key index design, well drilling and completion, surface engineering and operational risk warning and assessment, etc. The effect of field application was discussed and summarized. Firstly, trap dynamic sealing capacity evaluation technology for conversion of UGS from the fault depleted or partially depleted gas reservoirs. A key index design method mainly based on the effective gas storage capacity design for water flooded heterogeneous gas reservoirs was proposed. To effectively guide the engineering construction of UGS, the safe well drilling, high quality cementing and high pressure and large flow surface injection and production engineering optimization suitable for long-term alternate loading condition and ultra-deep and ultra-low temperature formation were developed. The core surface equipment like high pressure gas injection compressor can be manufactured by our own. Last, the full-system operational risk warning and assessment technology for UGS was set up. The above 5 key technologies have been utilized in site selection, development scheme design, engineering construction and annual operations of 6 UGS groups, e.g. the Hutubi UGS in Xinjiang. To date, designed main indexes are highly consistent with actural performance, the 6 UGS groups have the load capacity of over 7.5 billion cubic meters of working gas volume and all the storage facilities have been running efficiently and safely. | MA Xinhua ZHENG Dewen SHEN Ruichen WANG Chunyan LUO Jinheng SUN Junchang | 2018 | Petroleum Exploration and Development2018，45，3： | 2 |

| 7 | Reactive nano-essential oils for sustained release of essential oils and application to wallpaper显示文摘Essential oils are a volatile and aromatic substance with a variety of active biological activities.However,the excessive volatility and inconvenience of the use of essential oils limit their applications.In this study,we developed a reactive mesoporous silica nanoparticle(rMSNs)based on cyanuric chloride modification for essential oil encapsulation and commodity adhesion.The large pore volume and specific surface area of rMSNs facilitate the nanoparticles adhering to a large amount of essential oil and achieve the sustained release of essential oil,thus prolonging the fragrance retention time of essential oils.The reactive nanoessential oils can form covalent bonds with the wallpaper,thereby remarkably improving the adhesion of the reactive nano-essential oils on the wallpaper and preventing the reactive nano-essential oil from deadhering from the wallpaper.The active nano essential oil simultaneously overcomes the intense volatility of the essential oil and inconvenience in use,has a simple preparation process and low cost,and has great application potential. | Qiulian Hao Huan Peng Ruichen Zhao Jianze Wang Zhiguo Lu Jingwen Wang Jie Shen Yunwei Niu Zuobing Xiao Guiying Liu Jifu Hao Xin Zhang | 2022 | Chinese Chemical Letters2022，33，1： | 0 |

| 9 | Construction of high stability indium gallium zinc oxide transistor biosensors for reliable detection of bladder cancer-associated microRNA显示文摘Bladder cancer is the most common malignant tumours with high morbidity, mortality and recurrence.However, currently developed detection methods for bladder cancer-associated urine biomarkers are hindered by their extremely low abundance. Hence, the exploration of a highly sensitive and selective approach for the detection of trace bladder cancer-associated biomarkers in human urine is of vital importance for the diagnosis of bladder cancer. Herein, we developed a highly reliable indium gallium zinc oxide field effect transistor(IGZO FET) biosensor for the detection of bladder cancer-related biomarker micro RNA. The single-stranded DNA-functionalized IGZO FET biosensors exhibit high sensing reproducibility and stability with an ultralow detection limit of 19.8 amol/L. The device could also be used for quantitative detection of trace micro RNA in human urine samples and can effectively distinguish bladder cancer patients from healthy donors. The development of high performance IGZO FET biosensors presents new opportunities for the achievement of early-stage diagnosis of bladder cancer. | Jing Guo Ruichen Shen Xuejie Shen Bo Zeng Nianjun Yang Huageng Liang Yanbing Yang Quan Yuan | 2022 | Chinese Chemical Letters2022，33，2： | 0 |
| 10 | A STIR nucleic acid drug delivery system for stirring phenotypic switch of microglia in Parkinson’s disease treatments显示文摘Neuroinflammation is one of the three important pathological features in neurodegenerative diseases including Parkinson’s disease(PD).The regulation of neuroinflammation can reduce the severity of neurological damage to alleviate diseases.Numerous studies have shown that the phenotype switch of microglia is tightly associated with the nuclear factorκB(NF-κB)-mediated inflammatory pathway.Therefore,the small interfering RNA(siRNA)therapy for downregulating the expression of NF-κB,provides a promising therapeutic strategy for Parkinson’s disease treatments.Considering the brain delivery challenges of siRNA,a sequential targeting inflammation regulation(STIR)delivery system based on poly(amino acid)s is developed to improve the therapeutic effects of Parkinson’s disease treatments.The STIR system sequentially targets the blood–brain barrier and the microglia to enhance the effective concentration of siRNA in the targeted microglia.The results demonstrate that the STIR nanoparticles can transform microglial phenotypes and regulate brain inflammation,thus achieving neuronal recovery and abnormal aggregation ofα-synuclein protein(α-syn)reduction in the treatment of Parkinson’s disease.Herein,this STIR delivery system provides a promising therapeutic platform in PD treatments and has great potential for other neurodegenerative diseases’therapies. | Yanyue Wu Wenli Wang Xinyu Qiu Zhiguo Lu Weihong Ji Jie Shen Huan Peng Ruichen Zhao Jingwen Wang Tianlu Zhang Jun Yang Xin Zhang | 2023 | Nano Research2023，16，5： | 0 |
