International Journal of Dentistry, Volume 2026, Issue 1, 2026.Background Thermographic‐infrared changes during osteotomy surgery depend on the type of motor used, size, and system of the dental implant. This study undertakes the evaluation of these thermal variations for successful optimization of dependent surgical procedures while aiming toward reduced thermal damage to the bone tissue.

Analytical and numerical computation of air-gap magnetic fields in brushless motors with surface permanent magnets [PDF]
, 2000 This paper extends the theory of the air-gap magnetic field in permanent-magnet (PM) brushless motors. Scalar and vector potential solutions to the field equations are brought together to unify many of the important practical methods already in use.

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1394-1403, November 2025.Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration

Advanced Materials, Volume 37, Issue 41, October 16, 2025.Nanometer‐resolution mapping of individual quantum emitters in hexagonal boron nitride is achieved, allowing us to identify the 440 nm blue emitter as a substituted vertical carbon dimer. Leveraging this atomic‐level insight, the deterministic creation of isolated single 440 nm blue emitters is demonstrated through localized electron beam irradiation ...
