A spontaneously formed plasmonic-MoTe2 hybrid platform for ultrasensitive Raman enhancement
Cell Reports Physical Science, 2021 Summary: Development of highly sensitive, stable, and repeatable surface-enhanced Raman scattering (SERS) substrates is crucial for analytical detection, which is a challenge for traditional metallic structures.

Local manifestations of cometary activity [PDF]
, 2019 Comets are made of volatile and refractory material and naturally experience various degrees of sublimation as they orbit around the Sun. This gas release, accompanied by dust, represents what is traditionally described as activity.

SPERMICIDAL ACTIVITY OF SURFACE-ACTIVE AGENTS [PDF]
Reproduction, 1962 The spermicidal activities against human spermatozoa of a range of non-ionic, anionic and cationic surface-active agents have been determined with the method of Baker, Ransom & Tynen (1937). Although it has been concluded that surface-tension-lowering properties do not directly influence spermicidal power, the surfacetension/concentration curves of a ...

Accretion disk coronae of Intermediate Polar Cataclysmic Variables - 3D MagnetoHydro-Dynamic modeling and thermal X-ray emission [PDF]
, 2017 IPCVs contain a magnetic, rotating white dwarf surrounded by a magnetically truncated accretion disk. To explain their strong flickering X-ray emission, accretion has been successfully taken into account. Nevertheless, observations suggest that accretion

Mechanics of active surfaces [PDF]
Physical Review E, 2017 We derive a fully covariant theory of the mechanics of active surfaces. This theory provides a framework for the study of active biological or chemical processes at surfaces, such as the cell cortex, the mechanics of epithelial tissues, or reconstituted active systems on surfaces.
