Advanced Engineering Materials, EarlyView.A robot‐assisted laser processing method is proposed that enables the formation of surface‐tilted microanchors on metal substrates to improve metal–polymer joining. Using a six‐axis robotic platform, the laser beam's incidence angle, scanning path, and interline pitch can be precisely controlled, allowing the deliberate overlap of heat‐affected zones ...

Large-scale Evolution of Seconds-long Relativistic Jets from Black Hole–Neutron Star Mergers
The Astrophysical Journal Letters, 2023 We present the first numerical simulations that track the evolution of a black hole–neutron star (BH–NS) merger from premerger to r ≳ 10 ^11 cm. The disk that forms after a merger of mass ratio q = 2 ejects massive disk winds (3–5 × 10 ^−2 M _⊙ ).

Advanced Engineering Materials, EarlyView.The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.

The absence of jets in cataclysmic variable stars
, 2004 We show that the recently developed thermal model which successfully describes how jets are launched by young stellar objects, when applied to system containing disk-accreting white dwarfs naturally explain the otherwise surprising absence of jets in ...

Inverse-Compton drag on a Highly Magnetized GRB jet in Stellar Envelope [PDF]
, 2015 The collimation and evolution of relativistic outflows in $\gamma$-ray bursts (GRBs) are determined by their interaction with the stellar envelope through which they travel before reaching the much larger distance where the energy is dissipated and ...

Development of SiC Nanocomposites Using Direct Ink Writing Process
Advanced Engineering Materials, EarlyView.Herein, feedstock inks containing polycarbosilane and various concentrations of SiC nanoparticles (SiCnp) are investigated for fabricating ceramic matrix composites using a DIW 3D printing process. Characterization results from physical measurement, microstructure analysis, and thermal and flexural testing suggested that high‐performance CMC samples ...

M17 MIR: A Massive Star Is Forming via Episodic Mass Accretion
The Astrophysical Journal LettersWe analyzed the Atacama Large Millimeter/submillimeter Array (ALMA) band 6 data for the outbursting massive protostar M17 MIR. The ALMA CO J = 2–1 data reveal a collimated and bipolar north–south outflow from M17 MIR.

The Astrophysical Journal Letters, 2023 Spiral structures have been detected in evolved protostellar disks, driving the disk accretion toward the central protostars to facilitate star formation. However, it is still unclear if these structures can form earlier in young protostellar disks. With
