Advances in sulfur conversion-associated enhanced biological phosphorus removal in sulfate-rich wastewater treatment: A review.

Recently an innovative sulfur conversion-associated enhanced biological phosphorus removal (S-EBPR) process has been developed for treating sulfate-rich wastewater. This process has successfully integrated sulfur (S), carbon (C), nitrogen (N) and P cycles for simultaneous metabolism or removal of C, N and P; moreover this new process relies on the synergy among the slow-growing sulfate-reducing bacteria and sulfur-oxidizing bacteria, hence generating little excess sludge. To elucidate this new process, researchers have investigated the microorganisms proliferated in the system, identified the biochemical pathways and assessed the impact of operational and environmental factors on process performance as well as trials on process optimization.

Biodegradation Assessment of Poly (Lactic Acid) Filled with Functionalized Titania Nanoparticles (PLA/TiO) under Compost Conditions.

This paper presents a biodegradation study conducted for 90 days under standardized controlled composting conditions of poly (lactic acid) (PLA) filled with functionalized anatase-titania nanofiller (PLA/TiO nanocomposites). The surface morphology, thermal properties, percentage of biodegradation, and molecular weight changes at different incubation times were evaluated via visual inspection, scanning electron microscopy (SEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and gel permeation chromatography (GPC) by taking degraded samples from compost at the end of target biodegradation time interval. The rapid increase of crystallinity indicated that the PLA and PLA/TiO nanocomposites had heterogeneous degradation mechanisms under controlled composting conditions.

Strengthened and Thermally Resistant Poly(lactic acid)-Based Composite Nanofibers Prepared via Easy Stereocomplexation with Antibacterial Effects.

Strengthened poly(lactic acid) (PLA)-based materials with improved mechanical performance and improved thermal resistance, notably, are prepared by introducing stereocomplex crystallite (SC), an ideal filler, into the materials. Owing to the intermolecular hydrogen bond among the stereoisomer chains, the melting point of the special crystallite is up to 200 °C, which is 50 °C higher than the isostatic crystallite. The modulus of the PLA-based materials can be enhanced to several 100 MPa because of the integrated polymer chain arrangement.
