Advanced Functional Materials, EarlyView.The disordered growth of dendrites, corrosion, parasitic side reactions, slow de‐solvation kinetics, and inherent safety risks significantly hinder the practical deployment of conventional liquid electrolyte zinc‐ion batteries. In contrast, the novel PU‐EG+DMPA‐Zn polyurethane quasi‐solid‐state electrolyte, enriched with abundant polar functional ...

The Optimum Flight Speeds of Flying Animals
Journal of Avian Biology, 1998 Conventional models of bird flight combine metabolic, mechanical, and aerodynamic components to calculate the rate of fuel consumption and power required for flight, from which we may derive the optimal speeds flying animals should use in different situations.

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study
Advanced Functional Materials, EarlyView.This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

The role of vortices in animal locomotion in fluids
Applied and Computational Mechanics, 2014 The aim of this paper is to show the significance of vortices in animal locomotion in fluids on two deliberately chosen examples. The first example concerns lift generation by bird and insect wings, the second example briefly mentiones swimming and ...

Behaviour of dairy cows subjected to an aversive veterinary procedure. [PDF]
Biotemas, 2009 On small dairy farms that lack appropriate handling facilities, cows can be restrained and subjected to veterinary inspection or treatment in their milking environment, which in turn might influence the behaviour of the animals, disrupting routine ...

PLoS ONE, 2010 BackgroundThe holotype of the theropod non-avian dinosaur Microraptor gui from the Early Cretaceous of China shows extensive preservation of feathers in a halo around the body and with flight feathers associated with both the fore and hindlimbs.

Growth hormone secretion during space flight and evaluation of the physiological responses of animals held in the research animal holding facility [PDF]
The spaceflight of the Research Animal Holding Facility (RAHF) on the Space Laboratory 3 (SL 3) provided the opportunity to evaluate the suitability of the RAHF for housing and maintaining experimental animals during spaceflight, and to determine changes

Advanced Functional Materials, EarlyView.An adapted processing for solvent‐free argyrodite solid electrolyte films based on insights into degradation mechanisms of the widely used binder polytetrafluoroethylene is presented. By adapting the dry film processing, long‐term cycling in Si||NMC pouch cells is demonstrated over more than 1000 cycles with a capacity retention of more than 80%, and ...

Journal of Avian BiologyMigratory birds are physiologically challenged by intense exercise while fasting during flights that may last hours to days. Exercise‐induced oxidative stress could compromise flight performance by inducing mitochondrial dysfunction in the flight muscle.
