Probing and Tuning Strain‐Localized Exciton Emission in 2D Material Bubbles at Room Temperature

Advanced Materials, EarlyView.
This work provides an approach: 1) to directly visualize the associated exciton properties, revealing an intrinsic emission wavelength shift, and 2) actively modify local strain, enabling further exciton emission tuning. These findings provide direct insights into the strain‐localized emission dynamics in bubbles and establish a robust framework for ...

The Structure, Populations, and Kinematics of the Milky Way Central and Inner Bulge with OGLE, APOGEE, and Gaia Data

The Astrophysical Journal
We present an analysis of the structure, kinematics, and chemo-dynamical properties of the Milky Way bulge using RR Lyrae stars from Optical Gravitational Lensing Experiment (OGLE), and giant stars from APOGEE and Gaia that have distances placing them in

Analysis of inner fold and bulge defects on J55 steel for oil casing pipe

AIP Advances, 2019
Typical macroscopic and microscopic morphologies of inner fold and bulge defects of J55 oil casing pipe are observed, and inclusions and the metallographic structure near these defects are detected to obtain an understanding of the defect formation ...

The Gaia-ESO Survey: the most metal-poor stars in the Galactic bulge

, 2014
We present the first results of the EMBLA survey (Extremely Metal-poor BuLge stars with AAOmega), aimed at finding metal-poor stars in the Milky Way bulge, where the oldest stars should now preferentially reside.

Are there carbon stars in the Bulge? [PDF]

Symposium - International Astronomical Union, 1999
The Bulge carbon stars have been a mystery since their discovery by Azzopardi et al. (1991), because they are about too faint to be regarded as genuine AGB stars, if located inside the metal-rich Bulge . Part of the mystery can be solved if these carbon stars are related to the Sagittarius dwarf galaxy .

How Does a Delicate Insect Wing Resist Damage? Chitin Orientation Is Adapted to the Mechanical Demands at the Nanoscale

Advanced Materials, EarlyView.
Nanoscale chitin fiber orientations in the insect wing play a critical role in adapting to complex mechanical demands. These findings reveal two distinct and functionally adaptive chitin orientation patterns in the membranes that vary regionally, optimizing mechanical resilience and deformation control.

Planetary nebulae in the inner Milky Way [PDF]

, 2009
New abundances of planetary nebulae located towards the bulge of the Galaxy are derived based on observations made at LNA (Brazil). We present accurate abundances of the elements He, N, S, O, Ar, and Ne for 56 PNe located towards the galactic bulge.
