Modeling the Impact of Electrolyte Flow on Heat Management in a Li-Ion Convection Cell by Gao, Weiran, Drake, Javit, Brushett, Fikile R

“…We show, through physics-based electrothermal modeling and dimensional analysis of a single, planar LIB cell, that electrolyte convection can simultaneously draw heat from the cell and suppress heat generation from entropy change, charge-transfer, and ohmic losses, and that the cell temperature rise can be effectively mitigated when heat removal matches or exceeds heat generation. …”

Induced-charge electro-osmosis by Squires, Todd M., Bazant, Martin Z.

“…We describe the general phenomenon of ‘induced-charge electro-osmosis’ (ICEO) – the nonlinear electro-osmotic slip that occurs when an applied field acts on the ionic charge it induces around a polarizable surface. …”

A model for wet-casting polymeric membranes incorporating nonequilibrium interfacial dynamics, vitrification and convection by Lee, Hanyong., Krantz, William B., Hwang, Sun-Tak.

“…The predictions for initial casting-solution thicknesses of 75 and 125 m are markedly different. When densification induced convection is included, the 125 m film is predicted to enter well into the metastable region, thereby allowing supersaturation that promotes macrovoid defects. …”

A memory-efficient high-throughput architecture for lifting-based multi-level 2-D DWT by Hu, Yusong, Jong, Ching Chuen

“…The synthesis results in 90 nm CMOS process show that the proposed architecture achieves a better area-delay product by 60% and higher throughput by 97% when compared to the best existing design for the CDF (Cohen-Daubechies-Favreau) 9/7 2-D DWT.…”

Dye-sensitized Pt@TiO2 core–shell nanostructures for the efficient photocatalytic generation of hydrogen by Cao, Shao-Wen, Fang, Jun, Yin, Lisha, Liao, Yusen, Xue, Can

“…The dye-sensitization of these Pt@TiO2 core–shell structures allows for a high photocatalytic activity for the generation of hydrogen from proton reduction under visible-light irradiation. When the dyes and TiO2 were co-excited through the combination of two irradiation beams with different wavelengths, a synergic effect was observed, which led to a greatly enhanced H2 generation yield. …”

The road more travelled : how user-generated content can lead to homogenized travel journalism by Duffy, Andrew

“…Employing interviews and a survey, it finds that homogeneous travel attitudes and reports are highly influential in directing them in what to see and what to think about it—maintaining existing power relations and ideologies of tourism. Even when they actively expressed a desire for heterogeneous alternative viewpoints and agendas, Internet media directed them back towards mainstream tourist themes. …”

Hole-transporting small molecules based on thiophene cores for high efficiency perovskite solar cells by Mhaisalkar, Subodh Gautam, Li, Hairong, Fu, Kunwu, Boix, Pablo P., Wong, Lydia H., Hagfeldt, Anders, Grätzel, Michael, Grimsdale, Andrew C.

“…Two new electron-rich molecules, 2,3,4,5-tetra[4,4′-bis(methoxyphenyl)aminophen-4“-yl]-thiophene (H111) and 4,4′,5,5′-tetra[4,4′-bis(methoxyphenyl)aminophen-4”-yl]-2,2′-bithiophene (H112), which contain thiophene cores with arylamine side groups, are reported. When used as the hole-transporting material (HTM) in perovskite-based solar cell devices, power conversion efficiencies of up to 15.4 % under AM 1.5G solar simulation were obtained. …”

Rate-distortion optimized sparse coding with ordered dictionary for image set compression by Zhang, Xinfeng, Lin, Weisi, Zhang, Yabin, Wang, Shiqi, Ma, Siwei, Duan, Lingyu, Gao, Wen

“…In order to improve coding efficiency, the dictionary atoms are reordered according to their use frequencies when representing the representative image. As such, the remaining images can be efficiently compressed with sparse coding based on the reordered dictionary that is highly adaptive to the content of the image set. …”
