Highly dispersive photonic crystal-based guiding structures

, 2006
Propagating modes supported by Photonic-Crystal guiding structures can demonstrate very high group velocity dispersion close to a cut-off. We investigate here the wavelength dependence of the dispersion for different Photonic Crystal structures.

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

FEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

Ferroelectricity-driven strain-mediated magnetoelectric coupling in two-dimensional multiferroic heterostructure

Nature Communications
In the post-Moore era, CMOS technology faces challenges in storage and power consumption. Two-dimensional van der Waals ferromagnets, with their atomically sharp interfaces, enable heterostructure with ferroelectric materials.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Non-volatile electric-field control of room-temperature ferromagnetism in Fe3GaTe2 heterostructures

Nature Communications
Van der Waals multiferroic structures hold promises for advancing the development of low-power multifunctional nanoelectronics devices, but single-phase two-dimensional multiferroic materials are limited.

Improved machine learning framework for prediction of phases and crystal structures of high entropy alloys

Journal of Alloys and Metallurgical Systems
High-entropy alloys (HEAs) are gaining popularity because of their remarkable properties controlled by phases and crystal structures. In addition to that, in the field of material informatics, machine learning (ML) techniques have gained considerable ...

Cognitive and Neuroimaging Divergence Between Juvenile and Adult FUS Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive motor neuron degeneration. Fused in sarcoma (FUS)‐associated juvenile ALS (jALS) represents a distinct and aggressive subgroup with rapid deterioration and poor prognosis.
