Safeguarding the Photoluminescence of Silver Sulfide Nanocrystals in Biological Environments via Silica Shielding

open access: yesSmall, EarlyView.
Interactions with biomolecules can alter the photoluminescence of Ag2S nanocrystals, undermining near‐infrared imaging and thermometry. Incorporation into dendritic silica minimizes these interactions and preserves emission intensity, spectral response, and lifetime in plasma and whole blood. This shielding enables more reliable imaging and temperature

Measuring Public Sentiment on Corporate Sustainability Through Big Data and Social Media Analytics

open access: yesBusiness Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT Currently, corporate sustainability is primarily assessed through companies' own sustainability reports and evaluations conducted by NGOs and rating agencies. These approaches present several limitations, including potential reporting bias and limited transparency in evaluation methodologies. In response, this paper proposes CSR‐IRIS‐v2, a big

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

open access: yesBoreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

HvPHO1 Controls a Glucose 1‐Phosphate–SnRK1 Signalling Module That Coordinates Starch Accumulation in Barley Endosperm

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Developing barley grains must balance the use of imported sucrose between soluble sugars and storage starch, but how this balance is controlled remains unclear. Here we show that loss of the plastidial α‐glucan phosphorylase HvPHO1 causes starch and soluble sugars to accumulate concurrently in barley grains.
