Molecular Detection and Genetic Diversity of Bat‐Associated Bartonella spp. in Bat Ectoparasites Collected From Ratchaburi Province, Thailand

open access: yesVeterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Bat ectoparasites collected from four insectivorous bat species were identified through mitochondrial gene analysis. This study provides the first evidence of bat‐associated Bartonella species in ectoparasites, including bat flies (Phthiridium sp., Raymondia sp.

Frequency‐Dependent Seismic Velocity Variations Reveal Layered Aquifer Behavior Under Groundwater Fluctuations

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Frequency‐dependent seismic velocity variations (dv/v) provide depth‐resolved constraints on aquifer behavior under groundwater fluctuations. We analyze 17 years of dv/v time series from ambient noise interferometry in the Chiang Mai Basin, Thailand, and observe contrasting dv/v behavior below and above 1 Hz. By integrating GPS, meteorological,

Investigating the Effects of Build Height on Mechanical Behavior of Large‐Scale Laser Wire Directed Energy Deposited Nickel Titanium Alloy

open access: yesAdvanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
Laser wire directed energy deposition process was leveraged to fabricate large scale NiTi alloy wall. Evaluation of build‐height‐dependent tribo‐mechanical properties revealed significant differences in location specific sample characteristics. The middle region achieved optimal performance (superior wear resistance, balanced strength‐ductility ...

Impact of Various Sleeve Materials on Temperature Variations During Guided Endodontic Access Cavity Preparation Utilizing Finite‐Element Analysis

open access: yesClinical and Experimental Dental Research, Volume 12, Issue 1, February 2026.
ABSTRACT Purpose Guided endodontics allows precise access in challenging cases such as calcified canals; however, drilling can generate temperature increases that risk damaging periradicular tissues. This study aimed to evaluate the influence of different sleeve materials—zirconia, cobalt‐chromium (CoCr), and titanium—on temperature changes during ...

Emerging Triboelectric Nanogenerators for In‐Body Implantation

open access: yesSmall Methods, Volume 10, Issue 3, 9 February 2026.
This review explores functional implantable triboelectric nanogenerators in biomedical applications, discussing their mechanisms, electricity generation, and design approaches. To solve postimplantation challenges, four types of triboelectric nanogenerators (TENGs) are introduced: stretchable, bioadhesive, on‐demand biodegradable, and multiresponsive ...

Damage Behavior of Ni‐B and Ni‐B‐TiO2 Coatings on AISI P20 Steel Under Indentation and Bending

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 2, Page 559-573, February 2026.
ABSTRACT This study examines the influence of TiO2 nanoparticles on the structure, mechanical properties, and fracture behavior of Ni‐B coatings applied to heat‐treated AISI P20 steel. Mechanical performance was assessed through indentation and step‐by‐step three‐point bending tests on both coated and uncoated substrates.

Experimental Analysis and Physics‐Based Analytical Model on Twisted and Coiled Artificial Muscles

open access: yesAdvanced Engineering Materials, Volume 28, Issue 2, January 21, 2026.
Twisted and coiled artificial muscles made from silver‐coated nylon fibers are investigated through experiments and analytical modeling. The actuators achieve contractions up to 19.3% and specific work of 8 kJ kg−1, though efficiency remains limited (≈0.15%) by thermal losses.
