A High-Performance Aqueous Zinc-Bromine Static Battery.

iScience 2020 Aug 9;23(8):101348. Epub 2020 Jul 9.

State Key Laboratory of Chem/Biosensing and Chemometrics, College of Chemistry and Chemical Engineering, Hunan University, Changsha 410082, P.R. China; Advanced Catalytic Engineering Research Center of the Ministry of Education, Hunan University, Changsha 410082, P.R. China. Electronic address:

The highly reversible zinc-bromine redox couple has been successfully applied in the zinc-bromine flow batteries; however, non-electroactive pump/pipe/reservoir parts and ion-selective membranes are essential to suppress the bromine diffusion. This work demonstrates a zinc-bromine static (non-flow) battery without these auxiliary parts and utilizing glass fiber separator, which overcomes the high self-discharge rate and low energy efficiency while the advantages of the zinc-bromine chemistry are well preserved. It is achieved by a multifunctional additive, tetrapropylammonium bromide (TPABr), which not only mitigates the bromine cross-diffusion by regulating the fluidic bromine to a condensed solid phase but also provides a favorable interface for zinc electrodeposition toward non-dendritic growth.

Sci Rep 2020 03 24;10(1):5316. Epub 2020 Mar 24.

Museo del Jurásico de Asturias (MUJA), 33328, Colunga, Asturias, Spain.

Trace fossils represent the primary source of information on the evolution of animal behaviour through deep time, and provide exceptional insights into complex life strategies that would be otherwise impossible to infer from the study of body parts alone. Here, we describe unusual trace fossils found in marginal-marine, storm- and river-flood deposits from the Middle Devonian Naranco Formation of Asturias (northern Spain) that constitute the first evidence for infaunal moulting in a non-trilobite euarthropod. The trace fossils are preserved in convex hyporelief, and include two main morphological variants that reflect a behavioural continuum. Read More

Unique pelvic fin in a tetrapod-like fossil fish, and the evolution of limb patterning.

Proc Natl Acad Sci U S A 2018 11 5;115(47):12005-12010. Epub 2018 Nov 5.

Subdepartment of Evolution and Development, Department of Organismal Biology, Uppsala University, 752 36 Uppsala, Sweden.

All living tetrapods have a one-to-two branching pattern in the embryonic proximal limb skeleton, with a single element at the base of the limb (the humerus or femur) that articulates distally with two parallel radials (the ulna and radius or the tibia and fibula). This pattern is also seen in the fossilized remains of stem-tetrapods, including the fishlike members of the group, in which despite the absence of digits, the proximal parts of the fin skeleton clearly resemble those of later tetrapods. However, little is known about the developmental mechanisms that establish and canalize this highly conserved pattern. Read More
