Milk Protein Concentration Using Negatively Charged Ultrafiltration Membranes

open access: yesFoods, 2018
In this work, milk protein concentrate (MPC) was made using wide-pore negatively charged ultrafiltration membranes. The charged membranes were used for a six-fold volume concentration of skim milk and subsequent diafiltration to mimic the industrial MPC ...

Oxymatrine Inhibits Epithelial‐Mesenchymal Transition to Alleviate Airway Remodeling in Chronic Obstructive Pulmonary Disease by Suppressing the TGF‐β1/Smad Pathway

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study explored the therapeutic efficacy of oxymatrine (OMT, C15H24N2O2) in a murine model of cigarette smoke (CS)‐induced chronic obstructive pulmonary disease (COPD) and elucidated its underlying mechanisms. A COPD model was established in mice through prolonged exposure to CS, followed by intraperitoneal administration of OMT (50 mg/kg)

Modified polyethersulfone ultrafiltration membranes modified with citric acid crosslinked β-cyclodextrin for enhanced performance and azo dyes removal efficiency

open access: yesMaterials Research Express
Polyethersulfone (PES) polymer-based membranes with enhanced properties and performance were fabricated. A hydrophilic β -cyclodextrin ( β -CD) crosslinked with citric acid (CA), was used as an additive and polyethylene glycol 400 (PEG 400) was used as ...

Sediment trap preservative choice impacts particle‐associated microbial community composition

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Understanding and quantifying the microbial contribution to particulate organic matter (POM) flux and carbon cycling in the ocean relies largely on the collection of sinking POM. A critical aspect of evaluating microbial communities on sediment trap‐collected POM is their preservation until recovery and sample processing.

Process intensification of esterification reaction for the production of propyl butyrate by pervaporation [PDF]

open access: yes, 2017
Pervaporation is a membrane separation process vastly used for purification in chemical and allied industries. Esterification reaction can be intensified and enhanced by coupling with pervaporation reactor (PVR). Polyvinyl alcohol (PVA)/polyethersulfone (

Arsonic Acid Functional Polymers Enable Stabilization of Iron Oxide Nanoparticles in Aqueous Solution

open access: yesMacromolecular Rapid Communications, EarlyView.
Arsonic acid containing diblock copolymers are developed to incorporate arsonic acid moieties for surface anchoring to IONPs, along with water soluble PEG blocks to impart colloidal stability in aqueous environments. The resulting polymer‐coated IONPs are evaluated for stability in physiological media and cytocompatibility.

Hollow Fiber Membranes of Blends of Polyethersulfone and Sulfonated Polymers

open access: yesMembranes, 2018
Hollow fiber membranes (HFM) are fabricated from blend solutions of a polyethersulfone (PESU) with a sulfonated PESU (sPESU) or a sulfonated polyphenylenesulfone (sPPSU). The influence of different additives in the dope solution and different bore fluids

Study of improved resins for advanced supersonic technology composites. Part 1: Heteroaromatic polymers containing ether groups. Part 2: Curing chemistry of aromatic polymers and composite studies [PDF]

open access: yes
Fourteen ether-containing, aromatic dianhydrides have been synthesized from N-phenyl-3 or 4-nitrophthalimide and various bisphenols. The process involves nucleophilic displacement of activated nitro groups with bisphenolate ions.
