Discovery of a Bow-shock Nebula Around the Z Cam-type Cataclysmic Variable SY Cancri

The Astronomical Journal
We report the serendipitous discovery of a bow-shock nebula around the cataclysmic variable (CV) SY Cancri. In addition, SY Cnc lies near the edge of a faint H α -emitting nebula with a diameter of about $15^{\prime} $ .

Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

Advanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.

High-resolution X-Ray Spectroscopy of the Nova-like Cataclysmic Variable BZ Cam Using Chandra HETG: Diagnosis of the ADAF-like (Advective) Hot Flow

The Astrophysical Journal
Nova-likes, such as BZ Cam, are high-state cataclysmic variables showing hard X-ray emission that can be characterized by advective hot flows in the inner accretion disk.

Thermoresponsive Self‐Healing Carbon Nanotube‐Reinforced Dual‐Network Hydrogels for Wearable Sensors and Information Concealment

Advanced Materials Technologies, EarlyView.
A CNT‐reinforced dual‐network hydrogel combines ionic liquid‐mediated thermoresponsiveness, dynamic covalent crosslinking, and conductive nanostructures within a single adaptive material. The hydrogel exhibits ultrafast gelation, autonomous self‐healing, >1000% stretchability, reversible optical switching, and stable electromechanical sensing, enabling

Innate Immunocompetent hiPSC‐Derived Neurospheroids Capture Early CNS Responses to rAAV

Advanced Science, EarlyView.
Knowledge of human CNS immune responses to AAV‐based gene therapies remains limited due to the lack of immune‐competent human models. Here, a hiPSC‐derived 3D neuroimmune platform integrating neurospheroids and microglia is established using stirred‐tank bioreactors.

Minute-Cadence Observations of the LAMOST Fields with the TMTS: IV—Catalog of Cataclysmic Variables from the First 3-yr Survey

Universe
The Tsinghua University–Ma Huateng Telescopes for Survey (TMTS) started to monitor the LAMOST plates in 2020, leading to the discovery of numerous short-period eclipsing binaries, peculiar pulsators, flare stars, and other variable objects.

Robust Photocatalytic Hydrogen Evolution Over a Conjugated Metal‐Organic Framework Heterojunction

Advanced Science, EarlyView.
We report a conjugated coordination polymer, Cd‐TMT (TMT = 1,3,5‐trimercaptotriazine), featuring an intrinsic molecular‐level charge transport network. The conjugated TMT ligands facilitate strong intra‐ligand charge transfer, while their ordered π‐π stacking along the [111] direction establishes a continuous pathway for directional electron migration,

Models for various aspects of dwarf novae and nova-like stars [PDF]

, 1993
The first attempts to explain the nature of dwarf novae were based on the assumption of single-star phenomena, in which emission lines were assumed to be caused by circumstellar gas shells.

High-resolution spectroscopy and spectropolarimetry of some late F- / early G-type Sun-like stars as targets for Zeeman Doppler imaging [PDF]

, 2011
High-resolution spectroscopy and spectropolarimetry have been undertaken at the Anglo-Australian Telescope in order to identify suitable targets for magnetic studies of young Sun-like stars, for the proxy study of early solar evolution.
