[Dental Magnetic Resonance Imaging: Practical insights and evaluation of benefits and drawbacks in dentistry and oral and maxillofacial surgery].

Dental magnetic resonance imaging (MRI) has long been perceived as overly complex, costly, and limited in availability. Despite the numerous advantages of this radiation-free, non-invasive procedure for soft tissue diagnostics in the head and neck region, its imaging capabilities for hard tissue, such as bones and teeth, have thus far remained limited in comparison to conventional X-ray technology. In recent years, however, technological advances have led to a notable enhancement in the image quality and the range of applications of dental MRI.

New global minimum conformers for the Pt and Pt clusters: low symmetric species featuring different active sites.

Context: The study of platinum (Pt) clusters and nanoparticles is essential due to their extensive range of potential technological applications, particularly in catalysis. The electronic properties that yield optimal catalytic performance at the nanoscale are significantly influenced by the size and structure of Pt clusters. This research aimed to identify the lowest-energy conformers for Pt , Pt , and Pt species using Density Functional Theory (DFT).

Bias-Free Access to Orbital Angular Momentum in Two-Dimensional Quantum Materials.

The demonstration of a topological band inversion constitutes the most elementary proof of a quantum spin Hall insulator (QSHI). On a fundamental level, such an inverted band gap is intrinsically related to the bulk Berry curvature, a gauge-invariant fingerprint of the wave function's quantum geometric properties in Hilbert space. Intimately tied to orbital angular momentum (OAM), the Berry curvature can be, in principle, extracted from circular dichroism in angle-resolved photoemission spectroscopy (CD-ARPES), were it not for interfering final state photoelectron emission channels that obscure the initial state OAM signature.
