A thermoreversible gelatin‐based gel forms a soft, conformal bioelectronic interface on complex biological surfaces. The flowable precursor penetrates hair‐dense regions, solidifies in situ, and maintains low impedance through adaptive contact and hydration retention.

Sco X-1 is the brightest observed extrasolar X-ray source, which is a neutron star (NS) low-mass X-ray binary (LMXB) and is thought to have a strong potential for continuous gravitational waves (CW) detection due to its high accretion rate and relative ...

High-mass X-ray Binaries and OB-runaway Stars
High-mass X-ray binaries (HMXBs) represent an important phase in the evolution of massive binary systems. HMXBs provide unique diagnostics to test massive-star evolution, to probe the physics of radiation-driven winds, to study the process of mass accretion, and to measure fundamental parameters of compact objects.

Mg─Te chalcogenides address the leakage scaling trade‐off in ultrathin selector‐only memory. Structural partitioning in multiphase Mg─Te, combined with highly ionic Mg─Te bonding and Hf interfacial engineering, supports reliable 5 nm thickness operation at low write voltage with suppressed leakage current, narrow threshold voltage distributions, 10 ns ...

Quasiperiodic Oscillations in a Highly Magnetized Ultracompact X-Ray Binary 4U 1626-67
We report the detection of mHz quasiperiodic oscillations (QPOs) in four Nuclear Spectroscopic Telescope Array observations of 4U 1626–67 during its recent spin-down episode.

A sulfur‐doped lignin‐derived carbon‐coated Ni‐NiO‐MoO2 nanorod array was synthesized, exhibiting enhanced UOR performance ‐ due to lattice‐strain and built‐in electric field effects by multiphase heterogeneous interface in Ni‐NiO‐MoO2@SC, excellent corrosion resistance, mass‐transport ability, and long‐term stability (500 mA cm−2 at 1.53 V for 500 h ...

Highly Polarized Intrinsic Emission and Its Orthogonal Counterpart in Vela X-1
Vela X-1 is one of the most archetypal wind-fed X-ray pulsars (XRPs), and the emergence of its orthogonal polarization states reveals distinctive polarimetric properties.

Neutron star masses in X-ray binaries [PDF]
We discuss the determination of neutron star masses in X-ray binaries and explain the importance of such measurements. Examples are given of two of our recent neutron star mass determinations, in Cen X-3 and Vela X-1. We then discuss prospects for improving such measurements with SALT and the possibility of determining only the seventh neutron star ...

X-ray views of neutron star low-mass X-ray binaries
A neutron star low-mass X-ray binary is a binary stellar system with a neutron star and a low-mass companion star rotating around each other. In this system the neutron star accretes mass from the companion, and as this matter falls into the deep potential well of the neutron star, the gravitational potential energy is released primarily in the X-ray ...
