Valorization of Textile Waste: Enzymatic Upcycling of Terephthalic Acid Toward a Sustainable PET Value Chain

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT The rapid expansion of the global textile industry, driven by the fast‐fashion paradigm, which is characterized by low‐cost, short‐lived garments made from inexpensive synthetic fibers, has intensified environmental pressures through increased waste generation, resource depletion, microplastic pollution, and greenhouse gas emissions ...

Quantitative Partitioning of Photoautotrophic and Photoheterotrophic Contributions During Mixotrophic Growth of Scenedesmus obliquus

Biotechnology and Bioengineering, EarlyView.
Carbon and oxygen fluxes during photoautotrophic, photoheterotrophic and mixotrophic growth of Scenedesmus obliquus. ABSTRACT Mixotrophic growth of microalgae involves the simultaneous assimilation of inorganic and organic carbon sources, but the quantitative contributions of photoautotrophic and photoheterotrophic metabolisms remain poorly resolved ...

Processing‐Induced Changes in Bioactive Compounds, Physicochemical, Nutritional, and Sensory Properties of Asian Salted Noodles Fortified With Red Beetroot Flour

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Asian salted noodles (ASN) are popular in East and Southeast Asia and in parts of Europe and the Americas. However, ASN are deficient in certain nutrients (e.g., vitamins, minerals, and dietary fiber) and bioactive compounds.

Decarboxylative sulfation by persulfates

Chemical Science
Decarboxylative radical sulfation is achieved with persulfates functioning as both oxidants and sulfating agents to facilitate C–OSO 3 − bond formation. Synthesis of organosulfates from carboxylic-acid-based drugs may improve their metabolic profiles.

Interface‐Engineered Li–Ni–O/Ni Heterostructures With Tunable Vacancies on Biochar Enable Biomass‐to‐Hydrogen Conversion

Carbon Energy, EarlyView.
This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

Recent Developments in Azomethine Ylide-Initiated Double Cycloadditions

Molecules
Azomethine ylides (AMYs) have a nitrogen–carbon double bond and an electron lone pair on the nitrogen atom. They are essential 1,3-dipoles for [3+2] cycloadditions in the synthesis of pyrrolidine-containing heterocycles.

CO2‐Driven Synthesis of Holey Edge‐Carboxylated Graphene for Tunable Electronic Interactions in Cu–CeO2‐Catalyzed Water‐Gas Shift Reaction

Carbon Energy, EarlyView.
Holey‐structured, edge‐carboxylated graphene with a controlled specific surface area was synthesized using an environmentally friendly, CO2‐activated, KOH‐free ball‐milling process. ABSTRACT Graphene, notable for its high specific surface area, is ideal for catalyst support but faces challenges under harsh thermal catalytic conditions.

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate

Chemistry – A European Journal, EarlyView.
A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.
