Calibration of ultrafiltration membranes against size exclusion chromatography columns [PDF]
Using the extension of the concept of universal calibration parameter, yielding a relation between the hydrodynamic volume of molecules and the elution volume in sizeexclusionchromatography (SEC), to retention coefficients in ultrafiltration (UF), we ...

A glass‐ceramic from the BaO‐SiO2 chemical system emits light under mechanical loading provided it was submitted to UV irradiation prior to mechanical loading. This phenomenon is known as elasto‐mechanoluminescnence and, in the present case, it occurs thanks to the incorporation of a few percents of europium and holmium and an original synthesis route ...

Trophic status and phytoplankton in Lake Bidighinzu [PDF]
From March 1988 to April 1989 a survey was carried out on the phytoplankton of Lake Bidighinzu, a hypertrophic reservoir in Northern Sardinia. The purpose of this work was to assess the general limnological conditions of the reservoir after a diversion ...

White‐Light Emission in Zeolitic Imidazolate Framework Glasses
Broadband blue emission is discovered in ZIF‐62 through vitrification and hot‐pressing. This emission is significantly enhanced and redshifted when the ZIF‐62 glass is annealed above the critical temperature (1.07Tg), being attributed to an enhancement of ligand‐to‐ligand charge transfer.

This study focuses on the supramolecular self‐assembly of a newly developed family of compounds featuring s‐tetrazine. In particular, we highlight structure‐property relations and how gelation and mesogenic properties can be directed as a consequence of different side chains introduced in the system.
