Morphology of Nanostructured Tantalum Oxide Controls Stem Cell Differentiation and Improves Corrosion Behavior
Tantalum is receiving increasing attention in the biomedical field due to its biocompatible nature and superior mechanical properties. However, the bioinert nature of tantalum still poses a challenge and limits its integration into the bone tissue. To addr ...
Washington2023Unidirectional penetration approach for characterizing sulfate attack mechanisms on cement mortars and pastes
Karen Scrivener, Qiao Wang, William Wilson
Degradation of cementitious materials by sulfate ions is commonly classified into chemical and physical sulfate attack. So-called "physical" attack dominates in many field situations, but laboratory testing focuses on "chemical" attack under full-immersion ...
PERGAMON-ELSEVIER SCIENCE LTD2023Homogenization theory captures macroscopic flow discontinuities across Janus membranes
François Gallaire, Pier Giuseppe Ledda, Giuseppe Antonio Zampogna, Kevin Wittkowski
Janus membranes, thin permeable structures with chemical and geometrical asymmetric properties, show great potential in industrial separation processes. Yet the link between the micro- and macro-scale behaviours of these membranes needs to be established r ...
CAMBRIDGE UNIV PRESS2023An explainability framework for deep learning on chemical reactions exemplified by enzyme-catalysed reaction classification
Assigning or proposing a catalysing enzyme given a chemical or biochemical reaction is of great interest to life sciences and chemistry alike. The exploration and design of metabolic pathways and the challenge of finding more sustainable enzyme-catalysed a ...
2023Two-dimensional Hubbard model at finite temperature: Weak, strong, and long correlation regimes
We investigate the momentum-resolved spin and charge susceptibilities, as well as the chemical potential and double occupancy in the two-dimensional Hubbard model as functions of doping, temperature, and interaction strength. Through these quantities, we i ...
AMER PHYSICAL SOC2022High-content, arrayed compound screens with rhinovirus, influenza A virus and herpes simplex virus infections
Gerardo Turcatti, Fabien Kuttler
Viruses are genetically and structurally diverse, and outnumber cells by orders of magnitude. They can cause acute and chronic infections, suppress, or exacerbate immunity, or dysregulate survival and growth of cells. To identify chemical agents with pro- ...
2022Assessing Analytical Methods for the Rapid Detection of Lead Adulteration in the Global Spice Market
Lead adulteration of spices, primarily via Pb chromate compounds, has been documented globally as a growing public health concern. Currently, Pb detection in spices relies primarily on expensive and time-consuming laboratory analyses. Advancing rapid Pb de ...
AMER CHEMICAL SOC2022Monodisperse Selectively Permeable Hydrogel Capsules Made from Single Emulsion Drops
Esther Amstad, Alexandre Louis André Persat, Huachuan Du, Mathias Steinacher, Alice Cont
Capsules are often used to protect chemical and biological entities from the environment, to control the timing and location of their release, or to facilitate the collection of waste. Their performance depends on the thickness and composition of their she ...
2021Transport signatures of temperature-induced chemical potential shift and Lifshitz transition in layered type-II Weyl semimetal TaIrTe4
Oleg Yazyev, Quansheng Wu, Meng Yang
Temperature-induced Lifshitz transitions have been identified in several materials. Their chemical potential shows a substantial shift with changing temperature. The common feature of these materials is the coexistence of electron and hole pockets in the v ...
IOP PUBLISHING LTD2021Dissipation-Driven Selection under Finite Diffusion: Hints from Equilibrium and Separation of Time Scales
Paolo De Los Rios, Daniel Maria Busiello, Shiling Liang
When exposed to a thermal gradient, reaction networks can convert thermal energy into the chemical selection of states that would be unfavourable at equilibrium. The kinetics of reaction paths, and thus how fast they dissipate available energy, might be do ...
