The effect of temperature on lithium isotope separation by electrodialysis using La0.57Li0.29TiO3 (LLTO) electrolyte was investigated in the range 298.15–323.15 K. rates mass 6 and 7 isotopes (6Li 7Li) moving through LLTO into pure water were determined inductively coupled spectrometry. An Arrhenius-type dependence observed for rate transfer 6Li 7Li electrodialysis. apparent activation energy t...

Thank you very much Dean. I am delighted to be back at the Law School this afternoon. As I look around the room, I see people from my past and present. I was a student of Professor Gorman and Professor Lesnick in the early 1970s. A few years later, I worked with individuals who are in the audience from the State Department of Education in Harrisburg. Richard Mandell' was part of the interviewin...

A more sums than differences (MSTD) set is a finite subset S of the integers such that |S + S| > |S − S|. We construct a new dense family of MSTD subsets of {0, 1, 2, . . . , n − 1}. Our construction gives Θ(2n/n) MSTD sets, improving the previous best construction with Ω(2/n) MSTD sets by Miller, Orosz, and Scheinerman.

When the random intersection graph G(n,m, p) proposed by Karoński, Scheinerman, and Singer-Cohen in [8] is compared with the independent-edge G(n, p), the evolutions are different under some values of m and equivalent under others. In particular, when m = nα and α > 6, the total variation distance between the graph random variables has limit 0.

In 1971 Trotter (or Bogart and Trotter) conjectured that every finite poset on at least 3 points has a pair whose removal does not decrease the dimension by more than 1. In 1992 Brightwell and Scheinerman introduced fractional dimension of posets, and they made a similar conjecture for fractional dimension. This paper settles this latter conjecture.

Cranberry juice is recognized for its nutraceutical properties. Recently, it was demonstrated that it is possible to enrich a cranberry juice in antioxidants from another cranberry juice by an electrodialysis with filtration membrane (EDFM) process. In order to transpose this technology on an industrial scale for the production of an antioxidant enriched cranberry juice, the present work aimed ...

Electro-convective vortices in ion concentration polarization under shear flow have been of practical relevance for desalination processes using electrodialysis. The phenomenon has been scientifically disregarded for decades, but is recently embraced by a growing fluid dynamics community due its complex superposition of multi-scale gradients in electrochemical potential and space charge interac...

Currently, there is an enormous amount of energy available from salinity gradients, which could be used for clean hydrogen production. Through the use of a favorable oxygen reduction reaction (ORR) cathode, the projected electrical energy generated by a single pass ammonium bicarbonate reverse electrodialysis (RED) system approached 78 W h m(-3). However, if RED is operated with the less favora...

Most commercial anion exchange membranes (AEMs) deploy quaternary ammonium moieties. Alternative cation moieties have been explored in AEMs for fuel cells, but there are no studies focused examining alternative tethered cations ionic separations—such as organic acid transport via electrodialysis. H-cell and conductivity experiments demonstrate that benzyl 1-methyl imidazolium groups polysulfone...
