Effects of hybrid metal oxide nanoparticles on the tribological and emission attributes of algae‐derived biofuel in compression ignition engines

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The growing demand for sustainable fuels has accelerated the development of algae‐derived biodiesel for compression‐ignition engines. In this study, Chlorella vulgaris methyl ester (AME) exhibited physicochemical properties comparable to diesel and satisfied ASTM D6751 fuel quality requirements, making it suitable for blending.

Thumba (Citrullus colocynthis L.) seed oil: a potential bio-lubricant base-stock

Grasas y Aceites, 2015
Thumba seed oil, a minor, renewable tree borne oil, was exploited for the preparation of biolubricant base-stocks. The different base-stocks prepared were epoxy thumba oil (ETO), branched, 2-ethylhexyl ester (T2-EtHE), and polyol esters, namely ...

The research progress in polyethylene oxide polymer electrolytes

FlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

Macromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Multi‐Scale 3D Printing of Magnetic Polymer Nanocomposites with Controlled Particle Dispersion and Hyperthermic Response

Small, EarlyView.
Dispersion of magnetic nanoflowers in trimethylolpropane ethoxylate triacrylate to generate photocurable nanocomposites is described. Particle dispersion provides processability and target AC‐field stimulated temperature increases. Complex (DLP) printed structures with submicron features are demonstrated, and the potential for stimulated release of ...

Highly Efficient and Cytocompatible Panchromatic Photoinitiators for Photopolymerization and High‐Resolution 3D Printing beyond 450 nm

Small, EarlyView.
Phenothiazine photoinitiators P1 and P2 exhibit panchromatic photoinitiation through efficient SET with iodonium salts. P2 enables rapid red‐light polymerization, while both systems perform under sunlight and smartphone light. P1 supports 460 nm DLP 3D printing and shows lower cytotoxicity than TPO, offering safer photoinitiators for high‐precision ...

Recyclable and Degradable Covalent Adaptable Polymer Networks (CANs) Based on Dynamic Thiol–Yne Reactions

Journal of Applied Polymer Science, Volume 143, Issue 44, November 20, 2026.
Covalent adaptable networks based on activated alkynes, that is, alkynones, and multifunctional thiols (three and tetrafunctional) are tested in two different recycling strategies: (i) mechanical recycling based on their vitrimeric properties and (ii) chemical recycling based on the reversible thiol addition on the vinylene compound.
