Opposite Trends in Glass Transition and Vogel Temperatures in Long‐Chain Branched Poly(l‐Lactic Acid)

open access: yesJournal of Polymer Science, EarlyView.
The glass transition temperature (Tg), as determined by conventional DSC, increases from 326 K to 329 K while the Vogel temperature (Tv) decreases from 271 K to 255 K as the number of branch points per molecule increases from 0 to 3.3. ABSTRACT Poly(l‐lactic acid) (PLLA) is widely used as both a commodity thermoplastic and for engineering applications,

VTMaxBox: A reproducible practical tool for measuring voluntary thermal maximum in terrestrial ectotherms

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Thermal traits are central to understanding how ectotherms respond to environmental warming. However, not all thermal traits describe the same biological process. Critical thermal maxima quantify physiological failure, whereas preferred temperatures describe thermal selection under choice conditions.

Estimating the total mortality of seabirds following a marine heat wave

open access: yesConservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Scientists’ warning on the global destruction of rock outcrop ecosystems

open access: yesConservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Impact of Gentamicin‐Impregnated Collagen Sponge on the Incidence of Access Related Infections After Full‐Support Microaxial Flow Pump Therapy

open access: yesArtificial Organs, Volume 50, Issue 8, Page 1153-1163, August 2026.
Local application of gentamicin for wound closure after full‐support microaxial flow pump therapy. ABSTRACT Background Surgically implanted microaxial flow pumps (mAFP) are increasingly used for cardiogenic shock treatment. Standard mAFP explantation is performed bedside with a shortening of the vascular prosthesis, which may represent a potential ...
