How Proton Incorporation Reshapes Lattice Dynamics In BaSnO3‐Type Proton Conductors

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Yttrium‐doped BaSnO3 exhibits isotope‐dependent changes in its low‐energy vibrational density of states upon hydration. Comparison of dry, H2O‐, and D2O‐treated samples re‐veals mass‐dependent phonon renormalization linked to proton dynamics near oxygen va‐cancies, providing experimental insight into hydrogen‐coupled lattice excitations in proton ...

Neoplasias mamária e esplênica em cadela

Pubvet
No tocante às neoplasias mamárias e esplênicas em cães, a abordagem terapêutica cirúrgica é frequentemente o método de escolha, dado seu potencial curativo e a possibilidade de análise histopatológica subsequente.

Nódulos fibro-histiocíticos no baço de uma cadela: relato de caso

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2007
Descreve-se a ocorrência de múltiplos nódulos fibro-histiocíticos no baço de uma cadela Rottweiler, de sete anos. O diagnóstico foi feito por histopatologia e confirmado por imunoistoquímica positiva para ED1, CD18, vimentina e lisozima.

Complex Iridium Oxides Converge In Structure And Reactivity During Acidic Oxygen Evolution Electrocatalysis

Advanced Energy Materials, Volume 16, Issue 29, 5 August 2026.
Ir‐based double perovskites restructure during acidic oxygen evolution electrocatalysis through dissolution of non‐Ir cations and convergence toward IrOx active‐site motifs with similar structure and intrinsic activity across compositions. The identity of the dissolving cations controls dissolution and surface reconstruction kinetics, clarifying how ...

Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropods

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices.

Along the Benthic to Holoplanktonic Continuum: Seafloor Affinity Increases Distance‐Decay Rates Among Abyssal Communities

Global Ecology and Biogeography, Volume 35, Issue 8, August 2026.
ABSTRACT Aim Marine species ranges are often large, contributing to relatively high community similarity over space, with decreased ranges expected among taxa that have lower dispersal and/or higher substrate requirements. We tested for a weakening of biogeographic structuring among dispersing abyssal taxa along the benthic to holoplanktonic habitat ...

Influence of Alkaline Earth Barium on the Microstructure, Corrosion Behavior, and Cytocompatibility of Biodegradable Zinc

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Biodegradable Zn‐based alloys are promising candidates for temporary implants, yet excessive Zn2+ release during degradation may induce cytotoxicity and adverse tissue responses. In this study, Zn‐xBa alloys (x = 0.1 wt%, 0.5 wt%, 1.0 wt% and 3.0 wt%) were developed to achieve controlled corrosion behaviors with improved biocompatibility.

Aragonite Saturation Horizon Variability Along North Pacific Seamounts and Implications for Deep‐Sea Coral Reefs

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The 2014 discovery of living deep‐sea coral reefs along the Northwest Hawaiian Islands (NWHI) and lower Emperor Seamount Chain (ESC), despite the North Pacific's shallow aragonite saturation horizon (ASH) and high CaCO3 dissolution rates, underscores the need to understand the local seawater chemistry where these reefs persist. We investigated

Genomic Insights Into Population Structure and Demographic History of White Anglerfish (Lophius piscatorius) Throughout Its Range

Evolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Understanding population structure and clarifying species boundaries are essential for the sustainable management of exploited marine species. Although genomic resources for shallow‐water taxa have expanded rapidly, open‐water species remain comparatively understudied.
