Enhanced Electromagnetic Wave Absorption in Mapbi3 Hybrid Perovskite Through a Defect‐Tunable Green Synthesis

open access: yesSmall Structures, Volume 6, Issue 9, September 2025.
Mechanosynthesis allowed synthesizing and providing large amount of high‐quality MAPbI3 powders with defects tuned by grinding time. Mechanosynthesized MAPbI3 for 4 h dispersed in a polymeric matrix led to a marked enhancement in dielectric loss at 11.4 GHz, which makes this green synthesis approach promising for producing hybrid perovskites with ...

Diagnostic Performance of Four Serological Assays for Bovine Brucellosis and Optimised Cutoff Thresholds in an Endemic Region of Iran

open access: yesVeterinary Medicine and Science, Volume 11, Issue 5, September 2025.
A Venn diagram representing the overlaps and unique sets between four common serological tests used for Brucellosis detection: I‐ELISA, RBT, Wright and 2‐ME. Each circle corresponds to one of the tests, with varying levels of overlap indicating the number of positives shared between these tests.

Innovation and modernization of Gabčíkovo lock chambers

open access: yesStructural Concrete, Volume 26, Issue 4, Page 4015-4029, August 2025.
Abstract From 2019 to 2023, extensive innovation and modernization took place at the lock chambers of the Gabčíkovo waterworks to increase the safety and intensity of the water transport. The waterworks is located on the Danube River about 60 km southeast of Bratislava—the capital of Slovakia.

Population Decline for Plants in the California Floristic Province: Does Demography or Geography Determine Climate Change Vulnerability?

open access: yesDiversity and Distributions, Volume 31, Issue 8, August 2025.
ABSTRACT Aim The role of species' demography and geography can be difficult to disentangle when projecting future population decline under global change. By constructing and combining species‐specific ecological models for plants in a fire‐prone Mediterranean‐type ecosystem, we explored how demography and geography can differentially affect population ...

Shear Bearing Capacity Prediction of Steel-Fiber-Reinforced High-Strength Concrete Corbels on Modified Compression Field Theory

open access: yesBuildings
In order to analyze the shear mechanism of the steel-fiber high-strength concrete corbels, a calculation model for the shear bearing capacity of steel-fiber-reinforced high-strength concrete corbels was proposed based on the modified compression field ...

Gene Expression Shifts in Emperor Penguin Adaptation to the Extreme Antarctic Environment

open access: yesMolecular Ecology, Volume 34, Issue 15, August 2025.
ABSTRACT Gene expression can accelerate ecological divergence by rapidly tweaking the response of an organism to novel environments, with more divergent environments exerting stronger selection and supposedly, requiring faster adaptive responses. Organisms adapted to extreme environments provide ideal systems to test this hypothesis, particularly when ...
