The effects of PHB-g-MA types on the mechanical, thermal, morphological, structural, and rheological properties of polyhydroxybutyrate biopolymers.

This study investigates the grafting of polyhydroxybutyrate (PHB) chains with maleic anhydride (MA) in concentrations ranging from 5 % to 10 % by weight. This process was conducted during microwave treatment and using a reactive extruder, employing benzoyl peroxide (BPO) as the initiator. The impact of these methods on PHB's overall properties was thoroughly investigated.

Biopolymer blends of polyhydroxybutyrate and polylactic acid reinforced with cellulose nanofibrils.

Poly(lactic acid) (PLA) was used in an effort to enhance the mechanical properties of poly(hydroxybutyrate) (PHB) and the blends were reinforced with cellulose nanofibrils (CNF). The conventional and dynamic mechanical, morphological, thermal and rheological properties of the obtained composite blends were determined. The results showed that the mechanical properties of neat PHB noticeably increased attributable to the good interaction between the biopolymers and CNF from the scanning electron microscopy (SEM) characterization.

Psychological wellbeing of Turkish university students with physical impairments: an evaluation within the stress-vulnerability paradigm.

Generally, universities in developing countries offer little in the way of provisions and support (material, emotional, etc.) for disabled students. Therefore, disabled students experience considerable burdens and barriers in their educational life.
