Emerging locally delivered antimicrobial and immunomodulatory approaches for the prevention/treatment of peri‐implant diseases

open access: yesPeriodontology 2000, EarlyView.
Abstract Peri‐implant diseases are dysbiosis‐mediated inflammatory disorders that occur in susceptible hosts. Antimicrobials and immunomodulatory agents therefore might be pertinent as adjunctive measures in the treatment of such disorders. The aim of this narrative review was to examine the existing evidence and assess the effectiveness of emerging ...

Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

open access: yesExperimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

1.5 µm Emission Properties of Erbium‐Implanted Thin‐Film Lithium Niobate

open access: yesAdvanced Optical Materials, Volume 14, Issue 34, 11 September 2026.
Optically active Er3+ ions are incorporated into x‐cut lithium niobate on insulator utilising a focused ion‐beam implantation method capable of sub‐100 nm precision. The implanted regions exhibit telecom‐band emission, with a reduction in photoluminescence intensity and lifetime below 50 K, consistent with pyroelectric‐field effects in the host ...

High‐Power Continuous‐Wave Optical Waveguiding in a Semiconductor Nanowire

open access: yesAdvanced Photonics Research, Volume 7, Issue 9, September 2026.
An in‐line fiber–nanowire–fiber configuration provides efficient coupling of 1550 nm continuous‐wave light into and out of a single CdS nanowire. The output power increases linearly with input power, reaching 1.8 W and corresponding to a guided power of 2.5 W, demonstrating watt‐level continuous‐wave optical waveguiding in a subwavelength semiconductor
