Notably, nitro coumarins 6 and 7 demonstrated noteworthy activity against acetylcholinesterase, although they did not exhibit antioxidant properties. Among the tested compounds, four flavones and one coumarin displayed dual activity as both inhibitors of acetylcholinesterase

Luminescence of silver, thulium and ytterbium doped oxyfluoride glasses Pure Appl. Chem. (IF 1.8) Pub Date : 2024-01-23 Mikhail V. Shestakov, Victor V. Moshchalkov
Silver and lanthanide (Tm3+, Yb3+) doped oxyfluoride glasses have been prepared by melt-quenching method. The absorption of the glasses was measured in the range from 350 to 550 nm revealing the absorption edges of Ag nanoclusters and Tm3+ transition. The photoluminescence spectra of the glasses were detected in the range from 400 to 1100 nm under excitation in the range from 300 to 500 nm. The photoluminescence

Definition of the pnictogen bond (IUPAC Recommendations 2023) Pure Appl. Chem. (IF 1.8) Pub Date : 2024-01-22 Giuseppe Resnati, David L. Bryce, Gautam R. Desiraju, Antonio Frontera, Ingo Krossing, Anthony C. Legon, Pierangelo Metrangolo, Francesco Nicotra, Kari Rissanen, Steve Scheiner, Giancarlo Terraneo
This recommendation proposes a definition for the term “pnictogen bond”; the term pnictogen bond designates a subset of the attractive interactions between an electrophilic region on a pnictogen atom in a molecular entity and a nucleophilic region in another, or the same, molecular entity.

Roles of electrostatics and intermolecular electronic motions in the structural and spectroscopic features of hydrogen- and halogen-bonded systems Pure Appl. Chem. (IF 1.8) Pub Date : 2024-01-20 Hajime Torii
It is widely recognized that electrostatics plays a central role in the intermolecular interactions in condensed phases, as evidenced by the “electrostatics + Lennard-Jones” form of the potential functions that are commonly used in classical molecular dynamics simulations. Then, do we understand all about electrostatics in condensed phases? In this review, recent theoretical advances in relation to

Exploring the potential of Meldrum’s acid-bearing chain extenders for mechanical recycling of PET Pure Appl. Chem. (IF 1.8) Pub Date : 2024-01-18 Yonca Alkan Goksu
Poly(ethylene terephthalate) (PET) is a widely used thermoplastic polymer with exceptional properties, making it a cornerstone in various industries. However, the extensive global demand for PET, particularly in the packaging sector, has led to significant ecological concerns due to inadequate recycling rates. This paper explores the potential of Meldrum’s acid-based chain extenders as a solution to

A brief guide to measurement uncertainty (IUPAC Technical Report) Pure Appl. Chem. (IF 1.8) Pub Date : 2024-01-18 Antonio Possolo, David Brynn Hibbert, Jürgen Stohner, Olha Bodnar, Juris Meija
This Brief Guide reintroduces readers to the main concepts and technical tools used for the evaluation and expression of measurement uncertainty, including both classical and Bayesian statistical methods. The general approach is the same that was adopted by the Guide to the Expression of Uncertainty in Measurement (GUM): quantities whose values are surrounded by uncertainty are modeled as random variables

Automating the production of [Fe18FF2(BnMe2-tacn)] and investigating radiostabilisers for use with high-activity [18F]F− Pure Appl. Chem. (IF 1.8) Pub Date : 2024-01-05 Madelaine S. Woodward, Danielle E. Runacres, Julian Grigg, Imtiaz Khan, William Levason, Graeme McRobbie, Gillian Reid
The manual radiofluorination and purification of [FeF3(BnMe2-tacn)] (tacn = 1,4,7-triazacyclononane) using 18F− in aqueous EtOH has been translated to a GE FASTLab™ automatic synthesis platform and optimised by conducting a series of low-activity radiolabelling experiments to explore the effects of varying the precursor concentration, temperature, heating time, addition of NaOAc buffer and EtOH:H2O

Hydrogen as an energy carrier: constraints and opportunities Pure Appl. Chem. (IF 1.8) Pub Date : 2024-01-04 Nicola Armaroli, Elisa Bandini, Andrea Barbieri
The use of molecular hydrogen (H2) in the energy sector faces several technical and economic hurdles related to its chemical and physical properties, particularly volumetric energy density and mass. The production, transport and storage of hydrogen, both in gas and liquid form, are intrinsically inefficient and expensive. Moreover, the mass production of green hydrogen would preferably use surpluses

Analysis of individual nanoscale block copolymer vesicles by atomic force microscopy combined with time-resolved fluorescence microscopy Pure Appl. Chem. (IF 1.8) Pub Date : 2024-01-04 Holger Schönherr, Sergey I. Druzhinin, Stephan Handschuh-Wang, Daniel Wesner
We report on the analysis of individual dye loaded block copolymer (BCP) vesicles via a combination of confocal laser scanning microscopy (CSLM)/fluorescence lifetime imaging microscopy (FLIM) on the one hand and atomic force microscopy (AFM) on the other hand. AFM measurements on ATTO 647N-loaded poly(styrene-block-poly(acrylic acid)) (PS115-b-PAA15) vesicles were carried out with high spatial resolution

A critical review of the quantification, analysis and detection of radionuclides in the environment using diffusive gradients in thin films (DGT): advances and perspectives Pure Appl. Chem. (IF 1.8) Pub Date : 2023-12-18 Leonardo Pantoja, Hemda Garelick
This critical review explores the quantification, analysis, and detection of radionuclides in the environment using the diffusive gradients in thin films (DGT) technique. Radionuclides, unstable isotopes emitting ionising radiation, are present in the environment due to natural and anthropogenic sources for which concerns are raised about their impact on human health and ecosystems. DGT offers a unique

Simple preparation of silicone rubber Pickering emulsions using silica nanoparticles for water-borne thermal protection coating Pure Appl. Chem. (IF 1.8) Pub Date : 2023-12-13 Chao Gao, Chen He, Yibing Zeng, Xiaohui Wu, Xue Yan, Xiaofeng Wu, Chenguang Li, Boqian Li, Anchao Feng
In this study, we aimed to develop stable silicone rubber Pickering emulsions by employing silica nanoparticles as stabilizers in order to produce a water-borne thermal protection coating. Initially, silica nanoparticles were synthesized using the Stöber method and subsequently functionalized with γ-glycidoxypropyltrimethoxysilane (GTMS). The size and grafting efficiency of the GTMS-modified silica
