Excellent Comprehensive Electromechanical Properties in PZT‐Based Hard High‐Temperature Piezoceramics

open access: yesRare Metals, EarlyView.
ABSTRACT High‐power piezoelectric ceramics which have a wide operating temperature range are essential for sensor and actuator applications in extreme conditions. However, their development is fundamentally hindered by the inherent trade‐off among key parameters (TC, d33, Qm).

Regulating TGO Nucleation and Growth of MCrAlX Coatings via Femtosecond Laser Remelting: The Role of Reactive Elements in the Oxidation Resistance

open access: yesRare Metals, EarlyView.
ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

A link between increased temperature and avian body condition in a logged tropical forest

open access: yesConservation Biology, EarlyView.
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Heat Transfer in Porous Materials (1st Report Cooling Effect in Porous Metal Hollow Cylinder) [PDF]

open access: yes, 1973
One of the answers to the ever-increasing demands for materials able to withstand very high temperatures may be the use of porous materials cooled by the flow of fluid under pressure through the capillary passages inside the metal.Experimental studies of

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

open access: yesConservation Biology, EarlyView.
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

open access: yesConservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Evolutionary and environmental determinants of heat tolerance and acclimation capacity in herpetofauna

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Exploring heat tolerance and acclimation capacity can provide an effective approach to evaluating species’ sensitivity to extremely high temperatures due to climate warming. Despite some work on amphibian and reptile thermophysiological adaptation, related questions remain. We reviewed the literature to provide a synthesis of worldwide data on
