The Elusive [B(ReO4)4]− Anion in the Non‐Centrosymmetric Crystal Structure of K[B(ReO4)4]

open access: yesAngewandte Chemie International Edition, EarlyView.
Colorless crystals of K[B(ReO4)4] have been obtained from the reaction of KReO4 with B2O3 in a melt of Re2O7. According to single‐crystal structure analysis the compound has an anion which is built up by four (ReO4)‐tetrahedra coordinated to a central boron atom. Furthermore, the compound has been investigated by Raman spectroscopy and DFT calculations

Overview of Research Progress and Development of Cathode Materials for Aqueous Na‐Ion Batteries

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Aqueous sodium‐ion batteries (ASIBs) have now been viewed as the promising energy storage technique for the grid application due to their intrinsic safety and cost‐effectiveness. However, their energy density and cycling stability are still unsatisfactory accompanied by the narrow electrochemical stability window of water and parasitic side ...

Generalized Polyhedral DC Optimization Problems

open access: yes
The problem of minimizing the difference of two lower semicontinuous, proper, convex functions (a DC function) on a nonempty closed convex set in a locally convex Hausdorff topological vector space is studied in this paper.

Invariant manifold dynamics VIA polyhedral representation

open access: yes, 2015
In recent years, manifold dynamics has assumed an increasing relevance for analysis and design of low-energy missions, both in the Earth-Moon system and in alternative multibody environments, and several space missions have already taken advantage of the

Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.
