Ketal Protection of Glycerol for Selective Electrosynthesis of Glyceric Acid in Highly Alkaline Media

open access: yesAngewandte Chemie, EarlyView.
Using a ketal‐protected glycerol derivative (solketal) as the oxidation substrate enables site‐selective electrooxidation that suppresses C–C cleavage on non‐noble catalysts. Highly alkaline conditions promote reactive solketal alkoxide formation, weaken the Cα─H bond to facilitate dehydrogenation, and buffer local acidification, enabling a record‐high

Not All Agreements Are Equal: Heterogeneous Effects of RTAs on Latin American Agri‐Food Exports, 1990–2019

open access: yesAgribusiness, EarlyView.
ABSTRACT Since the final decade of the 20th century, Latin American countries have increasingly regarded the signing of regional trade agreements (RTAs) as a promising strategy for expanding their exports. Within this context, the main objective of this study is to assess the impact of RTAs on agri‐food exports in Latin America over the period 1990 ...

Inverse Vulcanization Through Epoxide Chemistry: A Low Temperature Non‐Olefin Route to Sulfur‐Rich Polymer Networks

open access: yesAngewandte Chemie, EarlyView.
Epoxide monomers undergo base‐catalyzed ring‐opening copolymerization with elemental sulfur to afford sulfur‐rich polymers under mild conditions. The resulting materials exhibit excellent mechanical performance, strong adhesion (up to 10 MPa on stainless steel), and outstanding reprocessability.

Long‐Term Outcomes After Stoma Creation in Crohn's Disease: A Retrospective Cohort Study of 422 Patients

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Aim Stoma creation is often required in Crohn's disease (CD), most commonly because of progressive anorectal disease. As stoma closure strongly influences long‐term quality of life and surgical decision‐making, this study evaluated the indications and long‐term outcomes of stoma creation in patients with CD.

From Holocene stability to industrial acceleration: shifting patterns of carbon accumulation in North American boreal and temperate lakes

open access: yesEnvironmental Research Letters
Lakes play a crucial role in the continental carbon cycle by burying large amounts of terrestrial organic matter (OM) in their sediments. Recent increases in carbon accumulation rates (CAR) have been linked to anthropogenic climate and land-use changes ...

Pancreatic Atrophy: A Narrative Review and Surgical Interpretation

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Pancreatic parenchymal atrophy pattern and intraoperative margin assessment guide surgical strategy. ABSTRACT Despite recent advances in multimodal management, pancreatic ductal adenocarcinoma remains a fatal malignancy. Early detection of indirect findings of pancreatic ductal adenocarcinoma is essential to improve treatment outcomes, drawing ...

Asking the 5 W's for designing next‐generation bioprocessing

open access: yesAIChE Journal, EarlyView.
Abstract Biotechnology is expanding beyond traditional, centralized fermentation and toward next‐generation bioprocessing paradigms that emphasize flexible deployment outside the laboratory with application‐specific performance. However, many bioprocesses fail to translate beyond proof‐of‐concept into industrially viable systems because early design ...

National and International Monitoring of Student Literacy and Numeracy Attainment: The Case for Rigorous Macro and Micro Analysis

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT In her 2024 paper Are Australian students' academic skills declining? Interrogating 25 years of national and international standardised assessment data, Larsen compiled an impressive summary of major international (PISA, PIRLS and TIMSS) and national (NAPLAN) standardised assessments pertaining to literacy and numeracy.
