Viboon Tangwarodomnukun, Ketsada Khamwiset, Huan Qi

The International Journal of Advanced Manufacturing Technology > 2019 > 104 > 9-12 > 3629-3645

Over-melting and vaporization of resin matrix are usually found along a cut in the laser machining of carbon fiber reinforced plastic (CFRP). This is considered as the heat-affected zone (HAZ) and it has to be minimized to avoid the delamination of CFRP laminates. This paper presents the use of water flow to cool down the CFRP during the laser machining process. A thin flowing water layer induced...

Cancer Letters > 2017 > 402 > C > 81-92

Multidrug resistance (MDR) interferes with the efficiency of chemotherapy. Therefore, developing novel anti-cancer agents that can overcome MDR is necessary. Here, we screened a series of colchicine binding site inhibitors (CBSIs) and found that 5-(3, 4, 5-trimethoxybenzoyl)-4-methyl-2-(p-tolyl) imidazol (BZML) displayed potent cytotoxic activity against both A549 and A549/Taxol cells.

Lan Lu, Huan Qi, Jie Zhu, Wen Xia Sun, more

Biomedicine & Pharmacotherapy > 2017 > 92 > C > 187-195

In the past 30 years, a variety of phage libraries have been extensively utilized to identify and develop tumor homing peptides (THPs). THPs specifically bind to tumor cells or elements of the tumor microenvironment while no or low affinity to normal cells. In this regard, the efficacy of therapeutic agents in cancer therapy can be enhanced by targeting strategies based on coupling with THPs that...

Annals of Nuclear Energy > 2017 > 99 > C > 328-334

In steam generators and other heat exchangers, there are a lot of tube bundles subjected to two-phase cross-flow. The fluctuating pressure on tube bundle structure caused by turbulence can induce structural vibration. The power spectral density (PSD) of buffeting force is usually required as the input of random vibration analysis. Since there is no generally accepted method to compute the normalized...
