Pump‐Probe Imaging of Ultrafast Laser Percussion Drilling of Glass in Single Pulse, MHz‐ and GHz‐Burst Regimes

Advanced Materials Interfaces, Volume 12, Issue 10, May 19, 2025.
Pump‐probe shadowgraphy of glass drilling is shown with a femtosecond laser operating in MHz‐ and GHz‐burst regime. A comparison with standard femtosecond micro‐processing using repetitive single pulses is provided. The ablation plume lifetime is measured in all three regimes, and the drilling dynamics of Through Glass Via (TGV) in GHz‐burst mode are ...

Effect of Spatial and Temporal Urban Isolation on the Genetic Diversity, Acoustic Variation, and Morphological Characteristics of an Urban Survivor Bird Species

Ecology and Evolution, Volume 15, Issue 4, April 2025.
Urbanization fragments habitats and isolates populations, reducing gene flow and driving divergence in genetic, acoustic, and morphological traits. Over ten years, isolated populations of white‐eared ground‐sparrows exhibited increased inbreeding, altered song characteristics, and changes in body and beak size, with significant correlations found ...

Early colonization of New Caledonia by ultrasonic crickets from New Guinea (Orthoptera: Gryllidae: Eneopterinae): Historical biogeography and description of a new genus

Systematic Entomology, Volume 50, Issue 2, Page 269-295, April 2025.
We describe Kanakinthus koniambo, a new genus and species of the subtribe Lebinthina endemic to New Caledonia using ultrasonic calls, and three new species of the genus Agnothecous. We provide a robust dated phylogeny of the subfamily Eneopterinae using eight molecular markers and a comprehensive taxon sampling with a focus on the Western Pacific ...

Interface triboelectricity

EcoEnergy, Volume 3, Issue 1, Page 105-130, March 2025.
This review systematically examines the working modes and fundamental mechanisms of liquid–solid triboelectric nanogenerators (TENGs), including the Wang Transition, hybrid EDL model, and tribovoltaic effects. The study provides insights into charge transfer at the liquid–solid interface and highlights broad applications in energy harvesting.

Gharial acoustic signaling: Novel underwater pops are temporally based, context‐dependent, seasonally stable, male‐specific, and individually distinctive

Journal of Anatomy, Volume 246, Issue 3, Page 415-443, March 2025.
Male gharials (Gavialis gangeticus) produce loud underwater POPs by rapid jaw clapping 1–3×. POPs are temporally based, context‐dependent, seasonally stable, and individually distinctive. The bulbous, cartilaginous “ghara” atop the snout is a sexually dimorphic unique feature.
