Tomographic microscopy of functionally graded polymer-derived SiCN ceramics with tunable gradients
Jürgen Brugger, Lorenz Hagelüken
Polymer-derived ceramics (PDCs) are a very attractive class of materials due to their excellent properties such as resistance to high temperatures and harsh environments, adjustability of mechanical and functional behavior, and compatibility with a broad r ...
London2024Large-cage occupation and quantum dynamics of hydrogen molecules in sII clathrate hydrates
Richard Gaal, Livia Eleonora Bove Kado, Umbertoluca Ranieri
Hydrogen clathrate hydrates are ice-like crystalline substances in which hydrogen molecules are trapped inside polyhedral cages formed by the water molecules. Small cages can host only a single H-2 molecule, while each large cage can be occupied by up to f ...
Aip Publishing2024Flash Melting Amorphous Ice
Marcel Drabbels, Ulrich Lorenz, Constantin Richard Krüger, Nathan Junior Mowry, Gabriele Bongiovanni
Water can be vitrified if it is cooled at high rates, which makes it possible to outrun crystallization in so-called no man’s land, a range of deeply supercooled temperatures where water crystallizes rapidly. Here, we study the reverse process in pure wate ...
2024Cyclic Peptides for Drug Development
Christian Heinis, Xinjian Ji, Alexander Lund Nielsen
Cyclic peptides combine a number of favorable properties that make them attractive for drug development. Today, more than 40 therapeutics based on cyclic peptides are in use, and new, powerful technologies for their development suggest that this number cou ...
2024Ion Spectroscopy Reveals Structural Difference for Proteins Microhydrated by Retention and Condensation of Water
Protein ubiquitin in its +7 charge state microhydrated by 5 and 10 water molecules has been interrogated in the gas phase by cold ion UV/IR spectroscopy. The complexes were formed either by condensing water onto the unfolded bare proteins in a temperature- ...
Washington2024Structure and dynamics of liquid water from ab initio simulations: adding Minnesota density functionals to Jacob's ladder
Ursula Röthlisberger, Justin Villard, Martin Peter Bircher
The accurate representation of the structural and dynamical properties of water is essential for simulating the unique behavior of this ubiquitous solvent. Here we assess the current status of describing liquid water using ab initio molecular dynamics, wit ...
Cambridge2024Reactions of hypobromous acid with dimethyl selenide, dimethyl diselenide and other organic selenium compounds: kinetics and product formation
Selenium (Se) is an essential micronutrient for many living organisms particularly due to its unique redox properties. We recently found that the sulfur (S) analog for dimethyl selenide (DMSe), i.e. dimethyl sulfide (DMS), reacts fast with the marine oxida ...
Cambridge2024Nanolithography of the nanocorral structure of chemisorbed oxygen atoms on the graphitic lattice
Kumar Varoon Agrawal, Shaoxian Li
Controlled atomic patterning is an attractive tool to fine tune properties of graphitic lattice. Several O-functionalized derivatives of graphitic lattice have been widely studied, e.g., graphene oxide, reduced graphene oxide, and functionalized carbon nan ...
Oxford2024Highly Hygroscopic Aerosols Facilitate Summer and Early‐Autumn Cloud Formation at Extremely Low Concentrations Over the Central Arctic Ocean
Julia Schmale, Andrea Baccarini
Arctic clouds are sensitive to atmospheric particles since these are sometimes in such low concentrations that clouds cannot always form under supersaturated water vapor conditions. This is especially true in the late summer, when aerosol concentrations ar ...
2024Multilayer diffusion-barrier composites based on microfibrillated cellulose from wood, bacterial and algae sources
This work is driven by the effort towards increased environmental sustainability and aims to develop a new food packaging material based on renewable materials, and more specifically cellulose as the most abundant biomass resource on Earth. Focus was on mi ...
