| 1 | An Experimental Study on Nanofluids Convective Heat Transfer Through a Straight Tube under Constant Heat Flux显示文摘In this work, the laminar convective heat transfer performance and the pressure drop of water-based nanofluids containing Al2O3, TiO2 and SiO2 nanoparticles flowing through a straight circular tube were experimentally investigated. The experimental results showed that addition of small amounts of nano-sized Al2O3 and TiO2 particles to de-ionized water increased heat transfer coefficients considerably, while the SiO2 nanofluids showed the opposite behavior attracting the authors' interests. An average of 16% and 8.2% increase in heat transfer coefficient were observed with the average of 28% and 15% penalty in pressure drop for Al2O3 and TiO2 nanofluids. | Ahmad Azari Mansour Kalbasi Masoud Derakhshandeh Masoud Rahimi | 2013 | Chinese Journal of Chemical Engineering2013，21，10： | 5 |
| 2 | Interventions of natural and synthetic agents in inflammatory bowel disease, modulation of nitric oxide pathways显示文摘Inflammatory bowel disease(IBD)refers to a group of disorders characterized by chronic inflammation of the gastrointestinal(GI)tract.The elevated levels of nitric oxide(NO)in serum and affected tissues;mainly synthesized by the inducible nitric oxide synthase(iNOS)enzyme;can exacerbate GI inflammation and is one of the major biomarkers of GI inflammation.Various natural and synthetic agents are able to ameliorate GI inflammation and decrease iNOS expression to the extent comparable with some IBD drugs.Thereby,the purpose of this study was to gather a list of natural or synthetic mediators capable of modulating IBD through the NO pathway.Electronic databases including Google Scholar and PubMed were searched from 1980 to May 2018.We found that polyphenols and particularly flavonoids are able to markedly attenuate NO production and iNOS expression through the nuclear factorκB(NF-κB)and JAK/STAT signaling pathways.Prebiotics and probiotics can also alter the GI microbiota and reduce NO expression in IBD models through a broad array of mechanisms.A number of synthetic molecules have been found to suppress NO expression either dependent on the NF-κB signaling pathway(i.e.,dexamethasone,pioglitazone,tropisetron)or independent from this pathway(i.e.,nicotine,prednisolone,celecoxib,β-adrenoceptor antagonists).Co-administration of natural and synthetic agents can affect the tissue level of NO and may improve IBD symptoms mainly by modulating the Toll like receptor-4 and NF-κB signaling pathways. | Aida Kamalian Masoud Sohrabi Asl Mahsa Dolatshahi Khashayar Afshari Shiva Shamshiri Nazanin Momeni Roudsari Saeideh Momtaz Roja Rahimi Mohammad Abdollahi Amir Hossein Abdolghaffari | 2020 | World Journal of Gastroenterology2020，26，24： | 5 |

| 4 | Gas–liquid flow mass transfer in a T-shape microreactor stimulated with 1.7 MHz ultrasound waves显示文摘This paper describes the application of ultrasound waves on hydrodynamics and mass transfer characteristics in the gas–liquid flow in a T-shape microreactor with a diameter of 800 μm. A 1.7 MHz piezoelectric transducer(PZT) was employed to induce the vibration in this microreactor. Liquid side volumetric mass transfer coefficients were measured by physical and chemical methods of CO_2 absorption into water and Na OH solution. The approach of absorption of CO_2 into a 1 mol·L^(-1) Na OH solution was used for analysis of interfacial areas. With the help of a photography system, the fluid flow patterns inside the microreactor were analyzed. The effects of superficial liquid velocity, initial concentration of Na OH, superficial CO_2 gas velocity and length of microreactor on the mass transfer rate were investigated. The comparison between sonicated and plain microreactors(microreactor with and without ultrasound) shows that the ultrasound wave irradiation has a significant effect on kLa and interfacial area at various operational conditions. For the microreactor length of 12 cm, ultrasound waves improved kLa and interfacial area about 21% and 22%, respectively. From this study, it can be concluded that ultrasound wave irradiation in microreactor has a great effect on the mass transfer rate. This study suggests a new enhancement technique to establish high interfacial area and kLa in microreactors. | Mona Akbari Masoud Rahimi Mahboubeh Faryadi | 2017 | Chinese Journal of Chemical Engineering2017，25，9： | 4 |
