Weak X‐Ray to Visible Lights Detection Enabled by a 2D Multilayered Lead Iodide Perovskite with Iodine‐Substituted Spacer

open access: yesAdvanced Science, Volume 10, Issue 21, July 27, 2023., 2023
A single‐crystal photodetector based on a novel 2D bilayered lead iodide perovskite with iodine‐substituted spacer, (2‐iodopropylammonium)2(formamidine)Pb2I7, is successfully developed for simultaneously detecting broadband (X‐ray to visible regimes) and ultraweak (nW cm−2 or nGy s−1 scale) lights with excellent performance, which sheds light on future

Chloride Binding Modulated by Anion Receptors Bearing Tetrazine and Urea

open access: yesChemPhysChem, Volume 24, Issue 2, January 17, 2023., 2023
Structural modifications of a simple anion receptor bearing urea and tetrazine fragments were studied in both ground and excited states. Receptor 2 shows slightly improved chloride complexation compared to the published receptor 4. Abstract Modulation and fine‐tuning of the strength of weak interactions to bind anions are described in a series of ...

Understanding the Effects of Binders in Gas Sorption and Acidity of Aluminium Fumarate Extrudates

open access: yesChemistry – A European Journal, Volume 28, Issue 5, January 24, 2022., 2022
A pinch of binder, a pinch of MOF: The effect of co‐extruding aluminium fumarate with either clays or silica gel binders has been investigated. Textural, microscopic, and spectroscopic techniques show the changes in porosity and surface sites, and CO2 and CH4 adsorption isotherms fitted an ideal Jensen‐Seaton adsorption model.

Shortening of membrane lipid acyl chains compensates for phosphatidylcholine deficiency in choline‐auxotroph yeast

open access: yesThe EMBO Journal, Volume 40, Issue 20, 18 October 2021., 2021
The interplay between acetyl‐CoA carboxylase and fatty acid synthase regulates lipid acyl chain length, and renders phosphatidylcholine redundant in Saccharomyces cerevisiae. Abstract Phosphatidylcholine (PC) is an abundant membrane lipid component in most eukaryotes, including yeast, and has been assigned multiple functions in addition to acting as ...

Jatropha Oil as a Substituent for Palm Oil in Biobased Polyurethane

open access: yesInternational Journal of Polymer Science, Volume 2021, Issue 1, 2021., 2021
Polyurethanes (PUs) are unique polymers that can be tailored to suit certain applications and are increasingly used in many industrial fields. Petrochemicals are still used as the main compound to synthesize PUs. Today, environmental concerns arise in the research and technology innovations in developing PUs, especially from vegetable polyols which are

Critical assessment of the sustainability of deep eutectic solvents: a case study on six choline chloride-based mixtures [PDF]

open access: yes, 2022
An outline of the advantages, in terms of sustainability, of Deep Eutectic Solvents (DESs) is provided, by analyzing some of the most popular DESs, obtained by the combination of choline chloride, as a hydrogen bond acceptor, and six hydrogen bond donors.
