Diagenetic isotope exchange in biocalcites for paleoclimate reconstruction

The oxygen isotope compositions of fossil biocalcites, such as foraminifera, bivalves, brachiopods, and belemnites have allowed for reconstructions of sea surface and deep ocean temperatures throughout the Phanerozoic and constitute the most important reco ...

Magneto-active elastic shells with tunable buckling strength

Pedro Miguel Nunes Pereira de Almeida Reis, Matteo Pezzulla, Dong Yan, Arefeh Abbasi

Shell buckling is central in many biological structures and advanced functional materials, even if, traditionally, this elastic instability has been regarded as a catastrophic phenomenon to be avoided for engineering structures. Either way, predicting crit ...

Nondestructive 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 ...

chi-Shell, a new spatial deployable lattice compared to traditional reticulated shells

Mark Pauly, Florin Isvoranu, Etienne Bouleau

The chi-Shells is a new kind of deployable reticulated shells that has features comparable to other traditional shells. Its deployment uses the mechanical properties of a beam grid to generate a three-dimensional shape. This new generation of reticulated s ...

X-Shell, a new spatial deployable lattice compared to traditional reticulated shells

Mark Pauly, Florin Isvoranu, Francis Julian Panetta, Etienne Bouleau

The χ-Shells is a new kind of deployable reticulated shells that has features comparable to other traditional shells. Its deployment uses the mechanical properties of a beam grid to generate a three-dimensional shape. This new generation of reticulated she ...

Tuning the Incorporation of Magnesium into Calcite during Its Crystallization from Additive-Free Aqueous Solution

Esther Amstad, Camelia Borca, Huachuan Du

Under ambient conditions, marine organisms are able to synthesize a variety of functional materials, ranging from eye lenses to protective shells through the meticulous control over magnesium incorporation into calcite during its crystallization. The mecha ...

Evolution of critical buckling conditions in imperfect bilayer shells through residual swelling

Pedro Miguel Nunes Pereira de Almeida Reis, Matteo Pezzulla, Dong Yan, Anna Lee

We propose and investigate a minimal mechanism that makes use of differential swelling to modify the critical buckling conditions of elastic bilayer shells, as measured by the knockdown factor. Our shells contain an engineered defect at the north pole and ...

Geometries and vibrational frequencies of small radicals: Performance of Coupled Cluster and more approximate methods

Jeremy Samuel Arey, Peter Rudolf Tentscher

We generated a new set of reference geometries of small radicals using experimental equilibrium structures, as well as a benchmark-quality coupled cluster additivity scheme including up to quadruples excitations (CCSDTQ). Using these geometries and a set o ...

Multi-Set Point Intermittent Contact (MUSIC) Mode Atomic Force Microscopy of Oligothiophene Fibrils

Holger Frauenrath, Liangfei Tian, Ruth Szilluweit

We developed MUSIC-mode atomic force microscopy (AFM) to emulate intermittent contact mode AFM without a feedback loop and in the absence of lateral forces. This single-pass approach is based On maps of amplitude-phase-distance curves and allows the height ...
