Sustainable levulinic acid production from inulin via hydrothermal conversion

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study investigates the hydrothermal conversion of inulin using potassium pyrosulfate to levulinic acid (LA). The Box–Behnken design approach was applied to optimize the conversion parameters and analyze the interactions influencing LA yield.

Mechanochemical synthesis Ba0.8Sr0.2TiO3 [PDF]

, 2011
Ba0.8Sr0.2TiO3 was prepared from the starting materials BaCO3, SrCO3 and TiO2 through solid state reaction. Mixture of these oxides was mechanically activated using a high-energy ball mill at different time intervals from 0 to 120 minutes. The crystal structure was determined by X-ray diffraction to obtain information about the composition of phase ...

Pt‐TiO2 mesoporous nanosystem co‐delivering phlorezin enables synergistic sonodynamic‐chemoimmunotherapy for hepatocellular carcinoma via directly targeting DDX5 and metabolic reprogramming modulation

BMEMat, EarlyView.
Abstract Hepatocellular carcinoma (HCC), ranking as the third leading cause of cancer‐related mortality globally, continues to pose significant therapeutic challenges. Here, we developed an innovative nanosystem, Phl@PT, based on Pt‐TiO2 nanoparticles for the co‐delivery of Phlorezin, presenting a novel approach for HCC treatment through sonodynamic ...

Advancing Upcycling and Regeneration of Spent LiFePO4: Failure Mechanisms and Recovery Strategies

Carbon Energy, EarlyView.
This review studies the failure mechanism to promote the upcycling regeneration of spent lithium iron phosphate (S‐LFP). It first summarizes the failure mechanisms of LFP batteries revealed via advanced characterization technologies and then explores the respective advantages and challenges of hydrometallurgy and direct regeneration methods.

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.

Bayesian Optimization of Solvent‐Free Thermal Amidation via Reactive Extrusion

Chemistry – A European Journal, EarlyView.
Thermal amidation between a carboxylic acid and an amine was successfully conducted in an extruder in the absence of solvent, coupling agent, or catalyst, relying on an adapted Bayesian Optimization protocol. Active pharmaceutical ingredient moclobemide was synthesized on a larger scale, achieving excellent yield and low Process Mass Intensity (PMI ...

Mechanochemical Synthesis of Lead-Free Halide Layered Double Perovskites: A Green and Scalable Approach. [PDF]

ChemSusChem
Herein we report a facile, green, and scalable synthetic alternative for the obtention of layered double perovskites (LDPs) via mechanosynthesis. This approach allows for the synthesis of phase‐pure LDPs in batches of up to 5 g within minutes. To our knowledge, this represents the largest scale and fastest synthesis of these materials reported to date.
