Fully Printed Organic Electrochemical Transistors With Low‐Resistance Electrodes on Planarized 3D‐Printed Substrates

open access: yesAdvanced Materials Technologies, EarlyView.
This paper explores integrating organic electrochemical transistors (OECTs) with planarized 3D‐printed substrates, utilizing ironing to enhance surface suitability for printing, dispense printing for thick, low‐resistance silver electrodes, and inkjet printing for semiconductor deposition.

Secular evolution and cylindrical rotation in boxy/peanut bulges: impact of initially rotating classical bulges

open access: yes, 2013
Boxy/peanut bulges are believed to originate from galactic discs through secular processes. A little explored question is how this evolution would be modified if the initial disc was assembled around a preexisting classical bulge.

Planetary nebulae in the inner Milky Way [PDF]

open access: yes, 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.

White Light Generation From YAG:Ce‐Doped Phosphate Glass‐Based Composite Fibers

open access: yesAdvanced Optical Materials, EarlyView.
The first white‐light‐emitting composite fiber based on YAG:Ce3+ phosphors in phosphate glass is developed. The glass composition is custom‐engineered to enhance thermal stability and to match YAG:Ce3+ refractive index, ensuring composite transparency.

Unifying the planar bar and the boxy bulge of the Milky Way

open access: yesEPJ Web of Conferences, 2012
For some time the Milky Way has been understood as a barred disk galaxy. Star count observations have provided evidence for two bars at apparently different orientations, the boxy bulge and a long planar bar.

Circularly Polarized Structural Color Pigments Tunable Across the Full Visible Spectrum

open access: yesAdvanced Optical Materials, EarlyView.
By infusing black dye into spherical shells of polymerized cholesteric liquid crystal, blue, green and red omnidirectional retroreflectors of circularly polarized structural color are achieved. They can be laid out on arbitrary surfaces without any need for index matching binder to define graphical information for robots and Augmented Reality devices ...

Kinematics of the X-shaped Milky Way Bulge: Expectations from a Self-consistent N-body Model

open access: yes, 2015
We explore the kinematics (both the radial velocity and the proper motion) of the vertical X-shaped feature in the Milky Way with an N-body bar/bulge model.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Stellar Proper Motions in the Galactic Bulge from deep HST ACS/WFC Photometry

open access: yes, 2008
We present stellar proper motions in the Galactic bulge from the Sagittarius Window Eclipsing Extrasolar Search (SWEEPS) project using ACS/WFC on HST. Proper motions are extracted for more than 180,000 objects, with >81,000 measured to accuracy better ...
