Tunable and Degradable Dynamic Thermosets from Compatibilized Polyhydroxyalkanoate Blends.
ACS Sustain Chem Eng

Renewable Resources and Enabling Sciences Center, National Renewable Energy Laboratory, Golden, Colorado 80401, United States.
Polyhydroxyalkanoates (PHAs) are versatile, biobased polyesters that are often targeted for use as degradable thermoplastic replacements for polyolefins. Given the substantial chemical diversity of PHA, their potential as cross-linked polymers could also enable similar platforms for reversible, degradable thermosets. In this work, we genetically engineered KT2440 to synthesize poly(3-hydroxybutyrate--3-hydroxyundecenoate) (PHBU), which contains both 3-hydroxybutyrate and unsaturated 3-hydroxyundecenoate components.

Despite being abundantly available and nutritious, corn stover and Ceara rubber tree leaves are rarely used as livestock feed. However, these agriculture byproducts contain hard to digest nutrients to be used as feed for livestock. This study evaluates the fermentation characteristics (pH levels, ammoniacal nitrogen (N-NH3), and total volatile fatty acid (VFA) production and nutrient digestibility (dry matter digestibility_DMD, organic matter digestibility_OMD) of a silage-based diet composed of a mixture of corn stover and Ceara rubber tree leaves in Etawa crossbred goats in vitro.

Statement Of Problem: Discoloration and the deterioration of mechanical properties lead to the replacement of maxillofacial prostheses. However, studies on the change in color and mechanical properties of high viscosity elastomers are lacking.
Purpose: The purpose of this in vitro study was to evaluate the influence of artificial aging on the mechanical and optical properties of high-consistency silicone elastomer (HCR) and compare these properties with a widely used liquid silicone rubber (LSR).
Biphasic Aromatic Amine-Cured Polybutadiene Polyurethane-Ureas for Simultaneous Bonding of Materials with Different Polarities.
Langmuir
March 2025
Center of Modern Analysis, Nanjing University, Nanjing 210023, China.
In this study, aromatic amine curing agents (A-HD, A-NPG, and A-DCP) were synthesized through the Michael addition of 3-aminobenzylamine with 1,6-hexanediol diacrylate, neopentyl glycol diacrylate, and octahydro-1H-4,7-methanoindene-1,5-diyldimethanediyl bisprop-2-enoate, respectively. The incorporation of these aromatic amine curing agents into low-polarity polybutadiene polyurethane-ureas balanced the polar and dispersion components of surface energy, enhancing the simultaneous bonding performance with materials of different polarities. Atomic force microscopy revealed that the prepared polybutadiene polyurethane-ureas exhibited a significant microphase separation between the soft and hard segments.

Department of Endodontics, School and Hospital of Stomatology, Wenzhou Medical University, Wenzhou, Zhejiang Province, People's Republic of China.
Objectives: To investigate the effectiveness of instrumentation using Protaper Next (PN; Dentsply Sirona, Maillefer, Ballaigues, Switzerland) and Waveone Gold (WG; Dentsply Sirona, Maillefer, Ballaigues, Switzerland) systems on the area of untouched surface (US), accumulated hard tissue debris (AHTD), and the filling ability of two obturation techniques on the volume percentage (vol%) of voids within C-shaped root canals of mandibular first premolars.
Methods: A total of 64 mandibular first premolars with C-shaped canals were scanned, matched, and subsequently assigned to two shaping groups (n = 32): PN and WG. After instrumentation, the specimens were randomly allocated into two obturation subgroups (n = 16): continuous wave compaction (CWC) and single-cone (SC) techniques.
