Mimicking Block Copolymer Self‐Assembly with One‐Pot Synthesized Polyphosphoester Gradient Copolymers

Advanced Functional Materials, EarlyView.
Degradable Polyphosphoester (PPE) gradient copolymers (GCPs) are synthesized via one‐pot copolymerization. We show that GCPs self‐assemble into nanostructures like polymersomes, effectively mimicking the behavior of traditional BCPs. The gradient strength is key, with softer gradients favoring micelles.

Organometallic Precursor‐Induced Gradient Architecture on Multilayer Nanoporous Graphene Membranes for Precise Organic Solvent Nanofiltration

Advanced Functional Materials, EarlyView.
Alumina growth narrows surface pores and seals non‐selective defects, enhancing selectivity while preserving the nanoporous graphene architecture. Additionally, the deposition enables gradient‐controlled structural modification, with intergrown alumina acting as a physical cross‐linker that stabilizes the laminar structure.

Airborne measurements of tropospheric ozone destruction and particulate bromide formation in the Arctic [PDF]

Aircraft profiles of O3 concentrations over the Arctic ice pack in spring exhibit a depletion of O3 beneath the surface temperature inversion. One such profile from the NOAA WP-3D Arctic Gas and Aerosol Sampling Program (AGASP) flights in April, 1986 ...

A pilot experiment to measure arctic pack-ice driving forces

, 1988
Pack-ice driving forces are synonymous with the limiting forces that can be transmitted through pack ice. Knowledge of this topic is important in relation to: ice loads on structures (the limiting driving force approach); ice motion modelling and forecasting; arctic ship routing.

Myeloperoxidase Luminol Reaction – A Novel Faecal Assay for Predicting Colonoscopy Findings in Patients with Ulcerative Colitis: A Pilot Cross‐Sectional Clinical Study

Advanced Healthcare Materials, EarlyView.
Can luminol detect faecal inflammation? This study explores the development and optimisation of a rapid novel assay ‐ Myeloperoxidase Luminol Reaction (MPOLR) for the detection of faecal myeloperoxidase activity. This simple and rapid luminol‐based approach competes with clinically validated faecal biomarkers in predicting endoscopic findings in ...
