Development of a Sustainable Biocatalytic Process for Geranyl Benzoate Production Using Immobilized Lipase

ChemistryOpen, EarlyView.
This study optimized solvent‐free geranyl benzoate production using Lipozyme 435, achieving 72% conversion in 6 hours. Open reactors improved yields (>99% in 48 hours) by removing inhibitorymethanol. Methyl benzoate reduced enzyme activity by 54%, though Lipura Flex showed better resistance. Human cell tests confirmed no cytotoxicity.

Mapping Photosynthesis Solely from Solar-Induced Chlorophyll Fluorescence: A Global, Fine-Resolution Dataset of Gross Primary Production Derived from OCO-2

Remote Sensing, 2019
Accurately quantifying gross primary production (GPP) globally is critical for assessing plant productivity, carbon balance, and carbon-climate feedbacks, while current GPP estimates exhibit substantial uncertainty. Solar-induced chlorophyll fluorescence

What factors influence the uptake of GPP (Green Public Procurement) practices? New evidence from an Italian survey [PDF]

Green Public Procurement (GPP) is becoming a cornerstone of environmental policies both at European Union and Member State level. Drawing upon a database of public authorities located in three Italian Regions, this paper assesses the determinants and ...

Dysregulated proteolytic cascades in Netherton syndrome: from molecular pathology to preclinical drug testing

The Journal of Pathology, EarlyView.
Abstract Netherton syndrome (NS) is a rare, severe, and often life‐threatening disease for which current therapeutic approaches are limited and show variable effectiveness. NS is characterized by excessive epidermal desquamation that results in a highly defective epidermal barrier, constitutive skin inflammation, allergies, and hair abnormalities.

Recyclability of Polystyrene Bead Foams: Degradation Behavior over 10 Extrusion Cycles

Polymer Engineering &Science, EarlyView.
This study investigates the multi‐cycle recycling of expanded polystyrene bead foam blended with virgin material. Material degradation is monitored by MFI, GPC, and mechanical testing. The results demonstrate that long‐term recyclability is feasible without progressive property loss, and that secondary high‐shear steps such as extrusion and pelletizing

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

PLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.
