Advances in Topological Thermoelectrics: Harnessing Quantum Materials for Energy Applications

Advanced Materials, EarlyView.
Topological materials offer a novel platform for thermoelectric energy conversion through unique band features, including band inversion, linear Dirac bands, surface states, and Berry curvature. These quantum characteristics enable enhanced longitudinal and transverse thermoelectric effects, establishing topological thermoelectrics as a promising ...

Can Life develop in the expanded habitable zones around Red Giant Stars?

, 2005
We present some new ideas about the possibility of life developing around sub-giant and red giant stars. Our study concerns the temporal evolution of the habitable zone.

Giant Circularly Polarized Luminescence Driven by Excited‐State Hybridization Between Molecular Emitters and Chiral Environments

Advanced Materials, EarlyView.
A fundamental chiroptical response amplification mechanism is revealed to massively enhance molecular helicene chiral emitters. The luminescent dissymmetry factor of the helicene emitter is amplified by 133 times through excited‐state hybridization with a polymeric chiral environment.

Optimizing the tip of the red giant branch distance estimator [PDF]

Proceedings of the International Astronomical Union, 2005
Until very recently, our knowledge of the local peculiar velocity field has been severely hampered by the lack of reliable distance measurements. HST has dramatically changed this situation, allowing astronomers to obtain accurate distances to more than 150 nearby galaxies.

Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

Advanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.

BV Stellar Photometry of 23 Galactic Globular Clusters [PDF]

Journal of Astronomy and Space Sciences, 1998
We report V-(B - V) CCD Color Magnitude Diagrams (CMDs) for 23 southern Galactic globular clusters. Limiting magnitudes for each cluster are between 18 and 20 magnitudes in V.

Human Schlafen 14 Cleavage of Short Double‐Stranded RNAs Underpins its Antiviral Activity

Advanced Science, EarlyView.
SLFN14 is associated with human diseases. SLFN14 is found to cleave RNAs containing short duplexes. The cryo‐EM structures of SLFN14 and SLFN14‐hairpin RNA complex reveal that SLFN14 assembles into a ring‐like dimer; two RNase domains form an RNA‐binding groove accommodating a hairpin RNA.

ON THE EVOLUTIONARY HISTORY OF PROGENITORS OF EHBS AND RELATED BINARY SYSTEMS BASED ON ANALYSIS OF THEIR OBSERVED PROPERTIES

Odessa Astronomical Publications, 2007
It has been shown quite recently (Morales-Rueda et al., 2003) that dB stars, extreme horisontal branch (EHB) objects in high probability all belong to binary systems.

Variations in Star Formation History and the Red Giant Branch Tip [PDF]

The Astrophysical Journal, 2004
We examine the reliability of the tip of the red giant branch (TRGB) as a distance indicator for stellar populations with different star formation histories (SFHs) when photometric errors and completeness corrections at the TRGB are small. In general, the TRGB-distance method is insensitive to the shape of the SFH except when it produces a stellar ...
