Separating PHB from Microorganism Broth

, 1999
目前“白色污染”正日益严重地威胁着自然环境，它造成了如土地质量严重退化而使农业减产等许多问题，世界各国也为寻找对策进行了大量的研究，其中使用可降解塑料是一个最有前途、最有效的办法，PHB（聚－β－羟基丁酸）正是其中研究最早、应用前景最广泛的生物可降解材料。但是，目前由于其成本较高，与廉价的石油工业高分子材料在价格上无法竞争，影响了它的广泛使用。为了降低成本，提高生产效率，本文针对发酵法生产PHB过程中存在的，发酵液难以分离沉淀，非有机溶剂提取PHB时分子量严重降低等问题，

Functional Anatomy of the Pharynx of Glycera tridactyla Schmarda, 1861 (Annelida: Glyceriformia: Glyceridae)

Journal of Morphology, Volume 287, Issue 6, June 2026.
Micro‐CT technology was used to investigate the functional anatomy of the pharynx in the polychaete Glycera tridactyla. The study revealed a complex system of pharyngeal muscles, including ring muscles, retensor muscles, intestinal retractor muscles, and longitudinal muscles of the buccal tube and oesophagus.

Obtenção e caracterização de filmes de PHB e de blendas de PHB com borracha natural

, 2008
Filmes de PHB puro e de blendas de PHB com borracha natural foram obtidos por prensagem a quente e por “casting” e foram avaliados segundo as propriedades morfológicas, estruturais, térmicas e mecânicas, além de sua suscetibilidade à biodegradação.

Design and Statistical Optimization of PLA Organoclay‐Based Dispersions for Recyclable Packaging Paper

Polymer Engineering &Science, Volume 66, Issue 6, Page 4321-4333, June 2026.
Through experimental design, polylactic acid (PLA)—organoclay dispersions were optimized to produce biobased coatings that have a high barrier potential while maintaining repulpability, promoting sustainable packaging solutions. ABSTRACT Performance and recyclability of paper coatings depend on precise control of polymer, surfactant, filler ...

Melt Electrospinning of Poly (ε‐Caprolactone)/Polyethylene Oxide/Polyethylene Glycol—Hydroxyapatite Nanocomposite Fibers: Morphology, Properties, and Hydrolytic Degradation

Polymer Engineering &Science, Volume 66, Issue 6, Page 4521-4536, June 2026.
The fabrication of nanocomposite fibers based on a ternary PCL/PEO/PEG blend reinforced with hydroxyapatite nanoparticles via melt electrospinning resulted in improved nanoparticle uniformity, fine‐tuning of the microstructure and mechanical properties, and accelerated hydrolytic degradation; features that make this system a promising platform for bone

Reductive Transformation of ALD TeO2 into Continuous and Impurity‐Free Tellurium Films

Small, Volume 22, Issue 32, 8 June 2026.
Atomic layer deposition forms a conformal TeO2 template that transforms to elemental Te through TeH2 mediated reduction using Te(SiMe3)2 and NH3. The transformation is self‐limiting and yields continuous crystalline Te with oxygen‐free bulk and interface even at ultrathin thicknesses.
