Pretreatment Effects of Conventional and Reactive Extrusion on LLDPE Waste Pyrolysis

Polymer Engineering &Science, EarlyView.
Schematic overview of the pyrolysis study using original and pretreated LLDPE waste samples. Pretreatment was performed via twin‐screw extrusion at 450°C: without additives (REX), with peroxide (REX‐RO2), or with polypropylene (REX–PP). All four samples underwent pyrolysis at 450°C–475°C for 15–45 min.

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Social, Technological, Economic, and Policy Factors in the Circular Economy Transition in Brazil

Sustainable Development, EarlyView.
ABSTRACT A well‐functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi‐structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

Small, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

(Dis)information Systems: a Systemic View of Disinformation

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Disinformation is an ancient social phenomenon that has found a favourable environment for dissemination in internet‐based social networks. While the scientific community seeks to address the problem by creating specific tools to detect and classify the various types of false information, we argue that systems thinking is necessary to ...

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

steel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...
