Wolf-Rayet content of the Milky Way

open access: yes, 2015
An overview of the known Wolf-Rayet (WR) population of the Milky Way is presented, including a brief overview of historical catalogues and recent advances based on infrared photometric and spectroscopic observations resulting in the current census of 642

Rising from the Ashes: A Metallicity-dependent Star Formation Gap Splits the Milky Way’s α Sequences

open access: yesThe Astrophysical Journal
The elemental abundance distribution of stars encodes the history of the gas-phase abundance in the Milky Way. Without a large, unbiased sample of highly precise stellar ages, the exact timing and nature of this history must be inferred from the ...

Connecting Droplet Adhesion with Sperm Kinematics: A New Paradigm in Sperm Quality Monitoring

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates direct experimental evidence to establish a nonintuitive connection between the motion characteristics of self‐propelled sperm cells and their surface interaction. Simultaneous motion visualization and cantilever‐deflection‐based adhesion characterization reveal that sperm‐cell droplets with higher motility exhibit lower surface

Dynamical Models of the Milky Way in Action Space with LAMOST DR8 and Gaia EDR3

open access: yesThe Astrophysical Journal
This work explores dynamical models of the Milky Way (MW) by analyzing a sample of 86,109 K giant stars selected through cross-matching the LAMOST DR8 and Gaia EDR3 surveys. Our earlier torus models of Q. Wang et al.

A Sustainable Route From Quartz to Bifunctional Material with Adsorbed Lanthanides for Enhanced Fluorescent Activation in Doxycycline Sensing

open access: yesAdvanced Materials Interfaces, EarlyView.
The aim of this study is to develop a sensor material based on natural quartz combined with La(III) and Ce(III), both detected in Ni‐MH batteries, as well as Eu(III), for reliable qualitative and quantitative analysis of doxycycline over a broad concentration range.
