The double-degenerate model for the progenitors of type Ia supernovae
The double-degenerate (DD) model, involving the merging of massive double carbon-oxygen white dwarfs (CO WDs) driven by gravitational wave radiation, is one of the classical pathways for the formation of type Ia supernovae (SNe Ia). Recently, it has been

Is There A Pure Electronic Ferroelectric?
The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

The Extremes of Thermonuclear Supernovae
The majority of thermonuclear explosions in the Universe seem to proceed in a rather standardised way, as explosions of carbon-oxygen (CO) white dwarfs in binary systems, leading to 'normal' Type Ia supernovae (SNe Ia).

Designing Memristive Materials for Artificial Dynamic Intelligence
Key characteristics required of memristors for realizing next‐generation computing, along with modeling approaches employed to analyze their underlying mechanisms. These modeling techniques span from the atomic scale to the array scale and cover temporal scales ranging from picoseconds to microseconds. Hardware architectures inspired by neural networks

The origin of ultra-compact binaries [PDF]
The origin of ultra-compact binaries composed of a neutron star and a low-mass (about 0.06 solar mass) white dwarf is considered. Taking account of the systemic losses of mass and angular momentum, it was found that a serious difficulty exists in the ...

From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...

Nearly 180° Field‐of‐View Metalens for Miniaturized Imaging Systems
A compact, single‐layer metalens is developed with an ultra‐wide field of view of ≈180 degrees. Utilizing a unique quadratic phase profile, this metalens overcomes traditional issues like axial and color dispersion. It operates across red, green, and blue wavelengths with non‐polarized light, promising enhanced imaging capabilities for integration into
