Performance Evaluation of 3D-Printed ABS and Carbon Fiber-reinforced ABS Polymeric Spur Gears

BioResources
Acrylonitrile butadiene styrene (ABS) polymer and carbon fiber reinforced acrylonitrile butadiene styrene (CF/ABS) spur gears were 3D-printed using fusion deposition modeling (FDM) with different fillet radii of 0.25, 0.50, and 0.75 mm.

pH Determination in Grape Must by Benchtop NMR Spectroscopy

ChemFoodChem, EarlyView.
Benchtop NMR spectroscopy enables electrode‐free pH determination in grape must. By modeling tartaric acid's chemical shift variation, pH is derived directly from NMR spectra alongside standard composition parameters. Validated against 100 samples, this integrated approach tracks pH changes during acidification, deacidification, and fermentation ...

Fatigue properties of spring reinforces polymer gears

, 2005
Failure of gears, occur surface pressure stress and fracture at base of teeth. For steel gears, it is known that process of carburizing increases fatigue strength. Internal stress on the surface increases of fracture fatigue strength. In this study fatigue properties of polypropylene gear reinforced with 1.2 mm wire diameter metallic springs was ...

Partially Biobased Polyurethanes With Reversibly Crosslinkable Furan Units Toward Recyclable Thermosetting Textile Fibres

Chemistry – A European Journal, EarlyView.
A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

Chemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,
