In the present research, hexagonal boron nitride (h-BN) films were deposited by reactive high-power impulse magnetron sputtering (HiPIMS) of the pure boron target. Nitrogen was used as both a sputtering gas and a reactive gas. It was shown that, using only nitrogen gas, hexagonal-boron-phase thin films were synthesized successfully.

Article Synopsis
  • Researchers developed biosensors using graphene field-effect transistors (G-FETs) to detect the COVID-19 spike S protein and its receptor, ACE2.
  • They compared directly synthesized graphene on silicon substrates with commercially transferred graphene on glass, finding the former to have superior sensitivity.
  • Both G-FETs achieved a detection limit as low as 10 attograms/mL, with a notable voltage shift indicating the presence of the spike S protein at various concentrations.

BACKGROUND Midpalatal suture ossification varies in patients of different ages, which can lead to making inaccurate presumptions when considering effective treatment timing based on chronological age. Chronological age provides only general information, whereas dental development correlates with skeletal growth, which suggests that tooth mineralization could be considered to be a precise criterion for determining the midpalatal suture's maturity. The present study was conducted to investigate the association between third-molar mineralization and midpalatal suture's maturation stages using cone-beam computed tomography (CBCT) images.

In the present research, hydrogen-free diamond like carbon films with embedded copper nanoparticles (DLC:Cu) were grown by simultaneous DC magnetron sputtering of the graphite and copper targets. X-ray photoelectron spectroscopy was used to define the composition of the samples. Atomic force microscopy studies of diamond, like carbon films containing different amount of copper, revealed wide range of the surface morphologies as well as sizes and shapes of the embedded copper nanoclusters.

Background: An aesthetic smile has a number of components, and people generally equate a good dental appearance with success in many areas of life. The features that determine smile aesthetics could provide significant insights into post-treatment satisfaction and may predict a patient's objectives when undergoing treatment. The purpose of this study was to evaluate how smile characteristics are perceived by dental students.

Article Synopsis
  • The study aimed to explore how genetics and the environment influence the development of third molar root stages by examining 162 same-sex twins.
  • Results indicated that females showed earlier root development compared to males, and monozygotic twins had stronger similarities in their development stages than dizygotic twins.
  • The findings suggest that about 60-63% of the variability in root mineralization is due to genetic factors, while environmental factors contribute less significantly, with common environments at 25-27% and specific environments at about 14%.
