Five-Membered Rings Create Off-Zero Modes in Nanographene
Oleg Yazyev, Kristians Cernevics, Ziyi Wang
The low-energy electronic structure of nanographenes can be tuned through zero-energy pi-electron states, typically referred to as zero-modes. Customizable electronic and magnetic structures have been engineered by coupling zero-modes through exchange and ...
Washington2023Mapping Orbital-Resolved Magnetism in Single Lanthanide Atoms
Harald Brune, Stefano Rusponi, Marina Pivetta, Fabio Donati, Aparajita Singha
Single lanthanide atoms and molecules are promising candidates for atomic data storage and quantum logic due to the long lifetime of their magnetic quantum states. Accessing and controlling these states through electrical transport requires precise knowled ...
AMER CHEMICAL SOC2021Nondestructive Prediction of the Buckling Load of Imperfect Shells
Tobias Schneider, Emmanuel Georges Albert Virot, Emilio José Lozano Vazquez
From soda cans to space rockets, thin-walled cylindrical shells are abundant, offering exceptional load carrying capacity at relatively low weight. However, the actual load at which any shell buckles and collapses is very sensitive to imperceptible defects ...
AMER PHYSICAL SOC2020Mechano-responsive microcapsules with uniform thin shells
Esther Amstad, Antoine Claude Jean Vian
Capsules often prolong the shelf-life of active ingredients, such as many types of drugs, food additives, or cosmetic substances, because they delay oxidation of these substances or prevent their reactions with molecules contained in the surrounding. If ca ...
2019Buckling of geometrically confined shells
We study the periodic buckling patterns that emerge when elastic shells are subjected to geometric confinement. Residual swelling provides access to range of shapes (saddles, rolled sheets, cylinders, and spherical sections) which vary in their extrinsic a ...
ROYAL SOC CHEMISTRY2019Capsules with submicron shells: production, stability, and leakage behavior
Capsules are often employed to prolong the shelf-life of active ingredients such as many drugs, food additives, or cosmetic substances because they delay their oxidation or prevent interactions with molecules contained in the surrounding. If designed prope ...
EPFL2018Scalable production of double emulsion drops with thin shells
Esther Amstad, Antoine Claude Jean Vian
Double emulsions are often used as containers to perform high throughput screening assays and as templates for capsules. These applications require double emulsions to be mechanically stable such that they do not coalesce during processing and storage. A p ...
2018On Establishing Buckling Knockdowns for Imperfection-Sensitive Shell Structures
This paper investigates issues that have arisen in recent efforts to revise long-standing knockdown factors for elastic shell buckling, which are widely regarded as being overly conservative for well-constructed shells. In particular, this paper focuses on ...
ASME2018Reducing the shell thickness of double emulsions using microfluidics
Esther Amstad, Antoine Claude Jean Vian
Double emulsion drops are well-suited templates to produce capsules whose dimensions can be conveniently tuned by adjusting those of the drops. To closely control the release kinetics of encapsulants, the composition and thickness of the capsule shell must ...
Springer Verlag2016Unusual Micrometric Calcite- Aragonite Interface in the Abalone Shell Haliotis similar to Mollusca, Gastropoda!
Species of Haliotis (abalone) show high variety in structure and mineralogy of the shell. One of the European species (Haliotis tuberculata) in particular has an unusual shell structure in which calcite and aragonite coexist at a microscale with small patc ...
