Enhanced thermal stability and flame retardancy of PLA through intumescent flame retardant with B-modified ZSM-5 as a synergistic agent

open access: yeseXPRESS Polymer Letters
In order to improve the inherent flammability of polylactic acid (PLA) and make this new biodegradable material more widely used, B-modified ZSM-5 (B/Z5) was designed as synergistic agent of intumescent flame retardant (IFR), composed of ammonium ...

É morfologia? [PDF]

open access: yesLinguística, 2009
This article focuses on two aspects pointed out as attributes of blends and acronyms: they are not universal and they are intentional. Their nonuniversality derives from the necessity of a writing system.

The blending of blended learning

open access: yesASCILITE Publications, 2011
Along with the increasing emphasis placed on blended learning approaches in higher education, has come a need to engage and support staff in developing knowledge and skills for designing and managing blended learning curricula. This paper describes one strategy for such support: an elective course within an existing Graduate Certificate in Higher ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Preparation and thermal properties of flame retardant phthalonitrile/epoxy blends

open access: yesScience and Engineering of Composite Materials, 2012
The blends were successfully prepared by the copolymerization of 2,2-bis [4-(3, 4-dicyanophenoxy) phenyl] propane (BAPh) and epoxy resins E-44 (EP) in the presence of 4,4′-diaminodiphenyl sulfone (DDS) as curing additive.

Solid state polymerization: its action on thermal and rheological properties of PET/PC reactive blends [PDF]

open access: yesPolímeros, 2013
The solid state polymerization (SSP) of PET/PC reactive extrusion blends - with and without cobalt catalyst - at different polymer ratios was studied. Thermal and rheological evaluations were performed. DSC results showed changes in the PET's Tg, Tch, Tm

Thermophysical, and rheological insights of polyethylene/wax blends

open access: yesFrontiers in Chemical Engineering
Blending wax with polyethylene (PE) has garnered significant attention in recent years due to its potential to enhance processing capabilities of polyethylene-based products. The miscibility of polyethylene and low molecular mass wax blends is a critical

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
