Frequency Analysis of a Superconducting Magnetic Bearing System in Ring Spinning Using an Eddy Current Damper

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT The conventional ring‐spinning process has been used for over a century, being one of the most used processes in the textile industry. However, this process has some disadvantages at high spindle speeds, such as friction in the traveler/ring components that generates heat, resulting in yarn breakages or lower‐quality production.

Proximal Pulmonary Artery Stiffening as a Biomarker of Cardiopulmonary Aging

Aging Cell, Volume 25, Issue 2, February 2026.
Mouse models revealed age‐associated increased circumferential stiffness of the proximal pulmonary artery that was associated with reorientation of collagen and decreased function of the lung and right ventricle. Age‐related transcriptional changes were indicative of senescence, ECM turnover, TGFβ signaling, and altered intercellular signaling among ...

Tranexamic Acid for Hyperpigmentation Disorders: A Literature Review on Efficacy and Safety in Melasma and PIH

Journal of Cosmetic Dermatology, Volume 25, Issue 2, February 2026.
ABSTRACT Background Hyperpigmentation disorders, including melasma and post‐inflammatory hyperpigmentation (PIH), are common dermatologic conditions associated with significant cosmetic and psychological burden. Tranexamic acid (TXA), an antifibrinolytic agent, has gained increasing attention due to its anti‐inflammatory and antimelanogenic properties.

Davemaoite Elasticity Reveals Slab‐Induced Heterogeneity in the Mantle Transition Zone

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The observed 2%–7% low‐shear velocity (VS) anomalies near the subducted slab at the bottom mantle transition zone (MTZ) indicate strong lateral heterogeneity, which is commonly attributed to subducted oceanic crust. However, davemaoite, a major constituent of the subducted oceanic crust, has been poorly constrained in its elasticity, hindering

Virus Enhanced Microrobots for Biofilm Eradication

Advanced Materials, Volume 38, Issue 2, 8 January 2026.
Biofilms resist antimicrobials across medicine, industry, and environments. We present virus‐conjugated microrobots synthesized hydrothermally and magnetically actuated. Their motion and viral specificity enable targeted binding, penetration, and delivery, outperforming bare microrobots.

Mechanoluminescent Aluminum Nitride Crystal for Super‐Sensitive Optical Manometry, Thermometry and Force Sensing

Advanced Materials, Volume 38, Issue 1, 2 January 2026.
This study reports the first discovery of intrinsic mechanoluminescence in undoped AlN crystals, accompanied by pronounced photoluminescence and persistent luminescence. It further demonstrates a defect‐emission–driven multifunctional optical sensing platform for force, pressure, and temperature detection, achieving exceptional sensitivities.
