Low NOx Methanol Diesel Engine with DME Torch Ignition Method.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B (1994)

Jianwei Guo Takemi Chikahisa Tadashi Murayama Masaharu Miyano

Dimethyl ether (DME) can be converted easily from methanol using γ-alumina catalyst, and it has very good compression ignition characteristics. The authors investigated a compression ignition methanol engine with aspiration of DME as an ignition improver, and reported that engine operation was sufficiently smooth without spark or glow plugs. In this study, the torch ignition method of DME was developed to reduce the necessary DME quantity and emissions. It was found that this method has greater potential for reducing the necessary DME quantity and for cleaner emissions compared to the aspiration method of DME.

Synthesis, Surface Property and Antimicrobial Activity of Cationic Gemini Surfactants Containing Adamantane and Amide Groups

Journal of Surfactants and Detergents (2014)

Xing Zhong Jianwei Guo Shuqin Fu Dongyu Zhu Jinping Peng

Abstract A series of novel cationic gemini surfactants, namely 1,3‐adamantanedicarboxylic acid bis(alkyldimethyl‐3‐ammoniopropyl amide) dibromide designated as [Ad‐2(amC n )] ( n = 12, 14, 16), containing adamantane, two amide groups, and two hydrocarbon chains, were synthesized from 1,3‐adamantanedicarboxylic acid. The surface‐active properties of the surfactants were investigated through surface tension and electrical conductivity measurement. A series of thermodynamic parameters such as standard free energy , enthalpy , and entropy of micellization were evaluated from electrical conductivity measurements in the temperature range from 288 to 308 K. The micellization for [Ad‐2(amC n )] is entropy‐driven at low temperature and enthalpy‐driven at high temperature. Further, the antimicrobial activity of the synthesized gemini surfactants against both Gram‐positive and Gram‐negative bacteria was also investigated, and this study showed that the compound [Ad‐2(amC 12 )] has excellent antibacterial activity against all studied bacteria.

Compatibilised and toughened of PLA/PCL blends via modified-chitosan linking amorphous regions: 4D printing and shape memory processes

Polymer Testing (2023)

Minzimo Song Shenghua Li Guiyou Zhu Jianwei Guo

It is valuable research to improve the compatibility and toughness of PLA/PCL blends while endowing them with shape memory & 4D printing capability. In this work, lactic acid/caprolactone-modified chitosan (mCS) was used to connect the amorphous region of PLA and PCL to achieve compatibilisation, toughening and 4D printing shape memory ability. The effects of different mCS additions on the morphology, crystalline behaviour, and thermal properties of PLA/PCL blends were observed to study the mechanism of compatibilisation and toughening. Adding 0.5 g mCS into 10 g PLA/PCL blends had the best compatibilisation and toughening effect. At the same time, the blends with this addition ratio had the best shape memory performance after 4D printing. The shape fixity and shape memory ratios of the 4D printing model were as high as 100% and 94.5%, respectively. This work provides a new way to fabricate biomedical devices and bionic components with 4D printing.

Preparation and applications of hydrophilic quaternary ammonium salt type polymeric antistatic agents

e-Polymers (2022)

Chenming Zhang Yihua Cui Shiping Lin Jianwei Guo

Abstract A novel ammonium salt type polymeric antistatic agent (PDSH) was synthesized from methacrylatoethyl trimethyl ammonium chloride, styrene, and 2-hydroxyethyl methacrylate via radical polymerization. Antistatic poly(acrylonitrile- co -butadiene- co -styrene) (ABS)/PDSH composites were prepared by blending PDSH with ABS resin. The results showed that the surface resistivity of ABS/PDSH composites with PDSH addition decreased significantly. The surface resistivity of ABS/PDSH composites containing 20 wt% PDSH was around 10 9 –10 10 Ω, which was about 10 6 times lower than that of neat ABS. At the same time, ABS/PDSH composites had good thermal stability and hydrophilicity. The PDSH was more uniformly dispersed within the ABS resin and had less influence on the mechanical properties of the composites. With the demonstrated properties, the prepared copolymer PDSH can serve as a well-integrated antistatic agent and display potential for the antistatic treatment of ABS.
