High‐Performance Polymer‐derived Ceramics in LCD 3D Printing
Advanced Science, EarlyView.This study highlights the potential of silicon oxycarbide‐based formulations for producing polymer‐derived ceramics with superior properties via LCD 3D printing. VMM‐based ceramics demonstrate a remarkable 50‐fold increase in compressive strength (up to 17 MPa) compared to SPR‐684, along with exceptional high‐temperature survivability (up to 1500 °C ...

Spring and Power in Hovering Ornithopters
Advanced Intelligent Systems, EarlyView.Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

Phase Separation in Giant Planets: Inhomogeneous Evolution of Saturn [PDF]
Icarus 164 (2003) 228-243, 2003 We present the first models of Jupiter and Saturn to couple their evolution to both a radiative-atmosphere grid and to high-pressure phase diagrams of hydrogen with helium and other admixtures. We find that prior calculated phase diagrams in which Saturn's interior reaches a region of predicted helium immiscibility do not allow enough energy release to

Pressure‐Driven Reactivity in Dense Methane‐Nitrogen Mixtures
Angewandte Chemie International Edition, Accepted Article.Carbon, nitrogen, and hydrogen are among the most abundant elements in the solar system, and our understanding of their interactions is fundamental to prebiotic chemistry. CH4 and N2 are the simplest archetypical molecules formed by these elements and are both markedly stable under extremes of pressure.

Stellar Physics and General Relativity
Astronomische Nachrichten, EarlyView.ABSTRACT The general theory of relativity is currently established as the most precise theory of gravity supported by observations, and its application is diverse ranging from astronomy to cosmology, while its application to astrophysics has been restricted only to compact stars due to the assumption that the Newtonian approximation is sufficient for ...

Validation of SATURN, a free, electronic, self‐administered cognitive screening test
Alzheimer’s & Dementia: Translational Research & Clinical Interventions, 2020 Background Cognitive screening is limited by clinician time and variability in administration and scoring. We therefore developed Self‐Administered Tasks Uncovering Risk of Neurodegeneration (SATURN), a free, public‐domain, self‐administered, and ...
