Ultra‐High Nickel Oxides as Cathode Materials for High‐Energy Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ultra‐high nickel layered oxides are among the most promising cathode materials for high‐energy lithium‐ion batteries, offering high specific capacity and significant utilization in both conventional lithium‐ion batteries and solid‐state batteries. This review article introduces the basic structure of ultra‐high nickel layered oxides, then delves into ...

Perspective Projection of an Ellipse and an Ellipsoid for Analytical View Factor Evaluation

Heat Transfer, EarlyView.
ABSTRACT Radiative view factors are fundamental quantities for evaluating radiative heat transfer between different surfaces. While analytical expressions of view factors have been evaluated for various types of basic geometries, including circular disks and spheres, extending these solutions to more complex geometries, such as ellipses and ellipsoids ...

Numerical Methods for Solving Convection-Diffusion Problems [PDF]

, 2012
Convection-diffusion equations provide the basis for describing heat and mass transfer phenomena as well as processes of continuum mechanics. To handle flows in porous media, the fundamental issue is to model correctly the convective transport of ...

Grow With the Flow? Impact of Experimental Floods on Riparian Vegetation in an Alpine River

River Research and Applications, EarlyView.
ABSTRACT Experimental floods have been proposed as a measure to mitigate effects of river flow regulation, primarily vegetation encroachment, streambed colmation, and loss of bed and channel mobility. In this study, we investigated the short‐ and long‐term biogeomorphic effects of an experimental flood programme conducted in the Spöl River (Swiss Alps)

Hyperspectral imaging has a limited ability to remotely sense the onset of beech bark disease

Remote Sensing in Ecology and Conservation, EarlyView.
Although hyperspectral imaging is a powerful remote sensing tool, it proved ineffective in predicting the progression of beech bark disease, except in its later stages, both at the canopy and leaf levels. While some alterations in chlorophyll, water content, and canopy structure may have influenced foliar reflectance at the canopy scale, as suggested ...

DuckNet: an open‐source deep learning tool for waterfowl species identification in UAV imagery

Remote Sensing in Ecology and Conservation, EarlyView.
Using drones with thermal‐RGB sensors and a deep learning model (RetinaNet with ResNet‐50), we surveyed non‐breeding waterfowl across restored wetlands in the Mississippi Alluvial Valley. Our model, DuckNet, achieved high accuracy and offers an open‐source, customizable tool for automated waterfowl detection to support conservation monitoring ...

UAVs unveil the role of small scale vegetation structure on wader nest survival

Remote Sensing in Ecology and Conservation, EarlyView.
In this study, we combine high‐resolution vegetation structural metrics derived from unmanned aerial vehicle (UAV) imagery with on‐field wader nest survival monitoring. We show that the immediate vegetation height and heterogeneity within a 2‐meter buffer surrounding the clutch of the recorded ground‐nesting wader species positively influenced its ...

Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins

Remote Sensing in Ecology and Conservation, EarlyView.
Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

Integrating Building Footprints and Bioenergy Potential to Support Effective Decentralised Energy Planning: A Scalable Framework Based on Open Data

Sustainable Development, EarlyView.
ABSTRACT This study develops a high‐resolution workflow to assess rural bioenergy gaps by integrating building‐based energy demand and locally collectable biomass supply across Jianghan Plain, China. Building footprint, height and density were extracted from the 10 m 3D‐GloBFP dataset and aggregated to 1 km grids to approximate demand intensity. County‐

Vortex Ratchet Effect in a NbC Strip With a Periodic Edge Indentation

Small Methods, EarlyView.
The image shows the nanoprinting of a superconducting nanostructure using focused ion beam induced deposition (top left), overlaid with numerically simulated patterns of current and magnetic flux quanta (bottom). An edge indentation breaks spatial symmetry, modifying the current density distribution and inducing nonreciprocal magnetic flux dynamics the
