Testing & Analysis

Move beyond ASTM D395 compression set to stress relaxation and DMA to predict contact stress retention and leakage risk in high-performance seals.

Researchers developed a novel, bio-based composite, enhanced with essential oil and chitosan, designed specifically for cosmetics packaging.

Moving beyond Melt Flow Index: select rheological measurements that match the deformation modes of injection molding and film blowing.

Optical sieve microcavities shift color when they trap nanoplastics, enabling fast detection, sizing, and counting with a standard microscope.

The European Chemicals Agency (ECHA) met to re-evaluate its 2023 proposal regarding per- and polyfluoroalkyl substances (PFAS).

Green coagulation and nanocellulose foams improve microplastic removal, yet integration challenges include clogging and media handling.

Machine learning (ML) enables rapid design of antimicrobial peptide (AMP)-mimetic polymers to treat bacterial infections.

Dynamic covalent networks allow crosslinked polyethylene to flow, weld, and relax stress during processing.

Fouling comes from additive volatility and interfacial energetics. Early shifts in cavity-pressure and ejector-force trends reveal their growth and prompt planned interventions.

As biomonitors, lichens show how green spaces buffer urban areas from atmospheric microplastic pollution.

PFAS contamination is now systemic across the UK. Engineers and regulators must decide between incremental control and full chemical elimination.

A new sodium-based method upcycles PTFE into fluorochemicals at room temperature, reducing PFAS risk and recovering valuable fluorine.
