AIChE Journal Article on Liquid-metal Membrane Technology Tops Altmetrics Charts

Schematic of the H2 permeation process through a dense liquid metal membrane involving sequential steps of: ① surface dissociative adsorption, ② subsurface penetration, ③ bulk metal diffusion, ④ egression to surface, and ⑤ reassociation of H atoms on the surface to form molecular H2.

New liquid-metal membrane technology may help make hydrogen fuel cell vehicles viable, read this AIChE Journal article for FREE here!

An AIChE Journal article, "Sandwiched Liquid Metal Membrane (SLiMM) for Hydrogen Purification" (AIChE Letter) by Ravindra Datta et al. of the Dept. of Chemical Engineering, Fuel Cell Center, Worcester Polytechnic Institute, discusses how new liquid-metal membrane technology may help make hydrogen fuel cell vehicles viable.

For the first time, the authors report a novel sandwiched liquid metal membrane (SLiMM) for hydrogen separation. Permeation experiments indicate that the Ga/SiC SLiMM has a permeability of 2.75 x 10-7 mol/ms * Pa0.5 formula at 500°C, which is 35 times higher than that for Pd under similar conditions. This promises a potential for application of SliMM in hydrogen purification.

The article, published in the May 2017 issue, has a very high Altmetric Attention Score of 86. This Attention Score is in the top 5% of all research outputs scored by Altmetric. This is one of the highest-scoring outputs from this source (#1 of 343). It is 92nd percentile compared to outputs of the same age. It is 80th percentile compared to outputs of the same age and source. More information appears online.

Altmetrics, which are “metrics and qualitative data that are complementary to traditional, citation-based metrics such as journal impact factor. Sourced from the Web, Altmetrics provide much information about how often journal articles and other scholarly outputs like datasets are discussed and used around the world.” Altmetrics track the use and discussion of research from online discussions and forums: social media, research blogs, public policy documents, news articles and more.

Each article published in AIChE journals (AIChE Journal, BioTM, BTPR, EP&SE, and PSP) on the Wiley Online Library includes an Altmetric score icon linked to an overview of attention for article published in the journal. Information is provided as to who is discussing the article, where those readers are located, and what their professions are.
