CVD Nanocrystalline Diamond Film Doped with Eu.

This paper submits experimental results of a study directed towards the formation of Eu ions' luminescent centers in CVD diamond films. A new approach is based on use of diamond nanoparticles with a surface modified with Eu ions for seeding at CVD growth. Nanocrystalline diamond films (NCD) doped with Eu have been grown from the gas phase on silicon substrates by microwave plasma-assisted CVD at a frequency of 2.

Total full-thickness skin grafting for treating patients with extensive facial burn injury: A 10-year experience.

Introduction: Facial burns are not only a severe burn injury, but result in psychological disturbance. The improvement of the methods of treating facial burns remains topical. The aim of the study was to evaluate the effectiveness of approach based on full-thickness skin autografting for facial burn injuries.

Testing the effectiveness and implementation of a brief version of the Common Elements Treatment Approach (CETA) in Ukraine: a study protocol for a randomized controlled trial.

Background: Mental illness is a major public health concern. Despite progress understanding which treatments work, a significant treatment gap remains. An ongoing concern is treatment length.

The origin of the piezoelectric effect in pyroelectric crystals.

The physical mechanism of piezoelectricity arising in crystals of all pyroelectric classes is described and discussed in detail. The piezoelectric effect of these crystals is postulated to be a consequence of changes in their spontaneous polarization under the impact of external forces (electric fields, mechanical stresses). This study shows which piezoelectric coefficients do exist in pyroelectric crystals.
