Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 9, September 2026.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

A cofactor‐promiscuous HMGR from the Lyme disease pathogen illuminates diversity in bacterial isoprenoid biosynthesis

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract The Lyme disease pathogen Borrelia burgdorferi contains a highly reduced genome lacking many primary metabolic pathways. However, B. burgdorferi retains the mevalonate pathway that synthesizes isopentenyl pyrophosphate (IPP), the precursor to the peptidoglycan carrier lipid.

Ni‐Induced Interface Refinement Enhances Strength‐Ductility Synergy in LPBF‐Processed Ti‐Mo‐Ni Alloy

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Microstructural refinement is a common strategy for strengthening additively manufactured titanium alloys because it promotes phase nucleation. Reducing the α/β interfacial formation energy is an effective way to increase the nucleation rate.

Synchronous Ultrasonic Impact Treatment for Regulating Microstructure and Properties of Laser‐Directed Energy Deposited In Situ TiC/Ti6Al4V Composites

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT In laser‐directed energy deposition (LDED) of TiC/Ti6Al4V composites, a low content of micron‐sized TiC provides a good strengthening effect on hardness and strength, but the improvement in plasticity remains a challenge. By introducing synchronous ultrasonic impact treatment (UIT) into the LDED process, an ultrasonic‐assisted LDED (UA‐LDED ...

GND Endorsements and Vote Share

open access: yes
Climate issues widely feature in policy discussions, but it is not clear if voters reward politicians who champion climate policies. In some countries, candidates and parties with an explicit climate agenda have done well in elections (Switzerland and ...
