High-strength cellulose nanofiber/graphene oxide hybrid filament made by continuous processing and its humidity monitoring

open access: yesScientific Reports, 2021
Human-made natural-fiber-based filaments are attractive for natural fiber-reinforced polymer (NFRP) composites. However, the composites' moisture distribution is critical, and humidity monitoring in the NFRP composites is essential to secure stability ...

Improving the Thermal Properties of Polycarbonate via the Copolymerization of a Small Amount of Bisphenol Fluorene with Bisphenol A

open access: yesInternational Journal of Polymer Science, 2022
Polycarbonate is an attractive transparent plastic with high mechanical/thermal properties. A family of copolycarbonates of bisphenol-A (BPA), 9, 9-bis (4-hydroxyphenyl) fluorene (BHPF), and diphenyl carbonate (DPC) were prepared by a transesterification

Weinberg’s Compositeness

open access: yesSymmetry, 2022
Nearly 60 years ago, Weinberg suggested a criterion for particle “compositeness”, which has acquired a new life with the discovery of new, exotic hadrons. His idea resonates with model-based intuition. I discuss the role it plays in the context of another of Weinberg’s creations, the model-independent framework of effective field theories.

Effect of pretreatment on microstructural stability and mechanical property in a spray formed Al-Zn-Mg-Cu alloy

open access: yesMaterials & Design, 2021
Aluminum alloys fabricated by spray forming (SF) technology are commonly followed by hot-working without heat treatments. A new approach that is a pretreatment before hot-working is proposed in the present work.

Synergistic Adsorption of Heavy Metal Ions and Organic Pollutants by Supramolecular Polysaccharide Composite Materials from Cellulose, Chitosan and Crown Ether [PDF]

open access: yes, 2014
We have developed a simple one-step method to synthesize novel supramolecular polysaccharide composites from cellulose (CEL), chitosan (CS) and benzo-15-crown 5 (B15C5). Butylmethylimidazolium chloride [BMIm+Cl−], an ionic liquid (IL), was used as a sole

Counting Composites [PDF]

open access: yesAustralasian Journal of Philosophy, 2021
I defend the thesis that Composition Entails Identity (CEI): that is, a whole is identical to all of its parts, taken together. CEI seems to be inconsistent, since it seems to require that the parts of a whole possess incompatible number properties (for instance, being one thing and being many things).

Carbon nanotubes and silver flakes filled epoxy resin for new hybrid conductive adhesives [PDF]

open access: yes, 2011
Combining conductive micro and nanofillers is a new way to improve electrical conductivity. Micrometric silver flakes and nanometric carbon nanotubes (CNTs) exhibit high electrical conductivity.

Penetration impact testing of self-reinforced composites [PDF]

open access: yes, 2014
Penetration impact resistance is one of the key advantages of self-reinforced composites. This is typically measured using the same setup as for brittle fibre composites.
