Agglomeration during reactive extrusion of particle-based biomass pellets [PDF]

open access: yesEPJ Web of Conferences
Creating mechanically sound aggregates from powder or grain-like feedstocks is a fundamental challenge across industries. One example is the production of pellets from organic materials, like wood residues and cereal grains, for biofuel and animal feed ...

Investigation of the Reaction Kinetics of Poly(butylene terephthalate) and Epoxide Chain Extender

open access: yesMacromolecular Materials and Engineering, 2023
Polyesters, such as poly (butylene terephthalate) (PBT), owe a rather low melt strength, which is considered as not beneficial for foaming. To overcome this issue, a typical attempt is the incorporation of chemical modifications—so‐called chain extenders

Study of the compatibilizer effect in the properties of starch/polyester blends [PDF]

open access: yesPolímeros, 2013
The mechanical, viscoelastic and structural properties of starch/ poly (butylene adipate co-terephthalate) (PBAT) blown films produced by reactive extrusion were evaluated using citric acid (CA) and maleic anhydride (MA) as compatibilizers.

Esters of Cinnamic Acid as Green Plasticizers for Polylactide Formulations with Improved Ductility

open access: yesMacromolecular Materials and Engineering, 2023
This study demonstrates the potential of different cinnamate esters, namely methyl trans‐cinnamate (MC), isobutyl cinnamate (IBC), allyl cinnamate (AC), and ethyl cinnamate (EC), as environmentally friendly plasticizers for polylactide (PLA). Plasticized

Reactive Extrusion Grafting of Glycidyl Methacrylate onto Low-Density and Recycled Polyethylene Using Supercritical Carbon Dioxide

open access: yesApplied Sciences, 2022
Glycidyl methacrylate (GMA) was grafted onto (recycled) polyethylene (PE) to design a new adhesive with better mechanical properties compared to non-grafted PE.

Effect of process parameters on the properties of LDPE/sepiolite composites

open access: yesPolímeros
This study examines the effect of processing parameters and reactive extrusion on the mechanical, thermal, morphological, and rheological properties of low-density polyethylene (LDPE) and sepiolite composites (LDPE/sepiolite: 95/5 wt/wt) produced by in ...

Methyl methacrylate-styrene copolymers prepared by utilizing the Trommsdorff effect in an inverted two-stage extruder

open access: yesMaterials Research Express, 2020
In this work, the influence of initial viscosity on the Trommsdorff effect was firstly investigated, and it was confirmed that 1000 ± 100 Pa · s of viscosity could be a criterion of the Trommsdorff effect. On this basis, a new inverted two-stage extruder

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
