Sustainable bioplastics manufacturing from renewable sources

open access: yesFEBS Open Bio, EarlyView.
Bioplastics are manufactured by using polymers from different bio‐based sources. These novel materials not only offer biodegradability but also possess various functional properties that make them suitable for diverse applications. Recent developments in the preparation of bioplastics are reported, highlighting the distinct properties of each type of ...

Coefficient of restitution for elastic disks

open access: yes, 1998
We calculate the coefficient of restitution, $\epsilon$, starting from a microscopic model of elastic disks. The theory is shown to agree with the approach of Hertz in the quasistatic limit, but predicts inelastic collisions for finite relative ...

Molecular Dynamics Simulations of Poly(dimethylsiloxane) Elasticity [PDF]

open access: yes, 2018
Cross-linked polymers have unique and advantageous properties due to the infinite elastic chains. Poly(dimethylsiloxane) (PDMS) belongs into a group of non-toxic, relatively inert and highly elastic polymers (elastomers).

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Numerical Investigation on Effective Elastic Modulus of Multifractal Porous Materials

open access: yesFractal and Fractional, 2022
The design of a novel material necessitates a fundamental understanding of its structure–property relation. Inorganic porous materials (media) such as natural soil and rock, and artificial ceramic and cement, exhibit multifractal characteristics in view ...

Oxidation-induced changes in mechanical properties of silicon nitride ceramics [PDF]

open access: yes, 1999
The effect of oxidation on the room-temperature mechanical properties of four different silicon nitride ceramics is investigated. The strength and the elastic modulus of the whole material and the hardness, the fracture toughness and the elastic ...
