Accumulation of Poly(3-hydroxybutyrate) Helps Bacterial Cells to Survive Freezing.

PLoS ONE, 2016
Accumulation of polyhydroxybutyrate (PHB) seems to be a common metabolic strategy adopted by many bacteria to cope with cold environments. This work aimed at evaluating and understanding the cryoprotective effect of PHB.

Progress in Biodegradable Nonwoven Materials for Personal Protective Applications

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
ABSTRACT Personal protective equipment generates large waste streams, underscoring the need for materials that deliver protection without persistent environmental costs. This study reviews biodegradable nonwoven options and relates material choice and disposal routes to barrier performance, comfort, and footprint.

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

The FEBS Journal, Volume 293, Issue 15, Page 4724-4743, August 2026.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Scalable Wheat Bran‐Algae Composites for Edible Electronics with Spray‐Coated Food‐Grade Conductive Inks

Advanced Electronic Materials, Volume 12, Issue 13, 6 July 2026.
A fully edible wheat bran–algae substrate is fabricated through scalable mould‐compression and spray‐coating, enabling robust, food‐grade platforms for sustainable electronics. A chitosan barrier improves water resistance and ink compatibility, while activated‐carbon conductive films form uniform electrodes with Ohmic behaviour.

Compatibilization and Reinforcement of PHB/PBAT Blends via Sequential Blending of Surface‐Modified Cellulose

Polymer Engineering &Science, Volume 66, Issue 7, Page 5358-5370, July 2026.
Sequential blending improved the mechancial properties of PHB/PBAT/cellulose composites as compared to the one‐step batch mixing method. ABSTRACT Polyhydroxybutyrate (PHB) is a natural and biodegradable polymer generated by bacteria. While its applications to potentially replace petroleum‐based plastics are severely limited due to its brittleness and ...

Shear Piezoelectricity in Poly(L‐Lactic Acid): From Molecular Chirality to Regenerative Materials Design

Small Structures, Volume 7, Issue 7, July 2026.
This review highlights how PLLA's molecular chirality and noncentrosymmetric chain packing generate intrinsic shear piezoelectricity without electrical poling, while crystallinity, optical purity, and molecular orientation define its design space. By distinguishing intrinsic d14 from device‐level outputs and connecting processing strategies to tissue ...

Thermo-mechanical characterization of PHB/PCL blend incorporated with carbon nanotubes

eXPRESS Polymer Letters
Polyhydroxybutyrate (PHB) is a polymer with great application potential; however, its brittleness and low mechanical strength restrict its use in many fields. This study investigated a strategy to overcome the mechanical limitations of PHB by blending it

Manipulation of Polyhydroxybutyrate Properties through Blending with Ethyl-Cellulose for a Composite Biomaterial

International Journal of Polymer Science, 2011
Polyhydroxybutyrate (PHB) is widely used as a biomaterial in medical and tissue-engineering applications, a relatively high crystallinity limits its application. Blending PHB with ethyl-cellulose (EtC) was readily achieved to reduce PHB crystallinity and
