The Kraft Break Sharply Divides Low-mass and Intermediate-mass Stars
The Astrophysical JournalMain-sequence stars transition at mid-F spectral types from slowly rotating (cooler stars) to rapidly rotating (hotter stars), a transition known as the Kraft Break and attributed to the disappearance of the outer convective envelope, causing magnetic ...

Beyond Mixing-length Theory: a step toward 321D
, 2015 We examine the physical basis for algorithms to replace mixing-length theory (MLT) in stellar evolutionary computations. Our 321D procedure is based on numerical solutions of the Navier-Stokes equations.

Pulsations as a Driver for LBV Variability [PDF]
, 2014 Among the most spectacular variable stars are the Luminous Blue Variables (LBVs), which can show three types of variability. The LBV phase of evolution is poorly understood, and the driving mechanisms for the variability are not known.

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries
Advanced Functional Materials, EarlyView.Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Magnetic Webs in Stellar Radiative Zones
The Astrophysical Journal LettersRotational evolution of stellar radiative zones is an old puzzle. We argue that angular momentum transport by turbulent processes induced by differential rotation is insufficient, and propose that a key role is played by “magnetic webs.” We define ...

Breaking Taylor–Proudman Balance by Magnetic Fields in Stellar Convection Zones [PDF]
The Astrophysical Journal Letters, 2018 Abstract We carry out high-resolution calculations for the stellar convection zone. The main purpose of this Letter is to investigate the effect of a small-scale dynamo on the differential rotation. The solar differential rotation deviates from the Taylor–Proudman state in which the angular velocity does not change along the rotational ...

Advanced Materials, EarlyView.Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Freeform Fabrication of Layered Halide Perovskite Nanowire Heterojunctions
Advanced Materials, EarlyView.‘All‐at‐once’ freeform fabrication of layered perovskite nanowire heterojunctions is realized by 3D printing employing meniscus‐guided crystallization. The integration of nanoscale additive manufacturing with layered halide perovskites will provide a versatile platform to freely design and realize highly stable perovskite‐based optoelectronic ...

The Astrophysical JournalSome physical processes that occur during a star's main-sequence evolution also affect its post-main-sequence evolution. It is well known that stars with masses above approximately 1.1 M _⊙ have well-mixed convective cores on the main sequence; however ...
