Dose dependence of ferromagnetism in Co-implanted ZnO [PDF]
We have studied the structural, magnetic and electronic properties of Co-implanted ZnO (0001) films grown on Al2O3 (1120) substrates for different implantation doses and over a wide temperature range. Strong room temperature ferromagnetism is observed with magnetic parameters depending on the cobalt implantation dose.

Define metabolites diagnostic of peri‐implantitis and predictive of future radiographic bone‐level (RBL) destruction. Metabolomics via Proton‐Nuclear Magnetic Resonance Spectroscopy of peri‐implant crevicular fluid. Cadaverine/Lysine and Putrescine signatures predict peri‐implantitis, while alpha‐ketoglutarate diagnoses implant health.

Fatigue behaviour of titanium dental endosseous implants [PDF]
In this work two different titanium dental implants are analyzed in order to evaluate their mechanical strength. An ad-hoc designed experimental apparatus is prepared to test against fatigue these implants in a way that approximates as much as possible ...

Deep level transient spectroscopy study for the development of ion-implanted silicon field-effect transistors for spin-dependent transport [PDF]
A deep level transient spectroscopy (DLTS) study of defects created by low-fluence, low-energy ion implantation for development of ion-implanted silicon field-effect transistors for spin-dependent transport experiments is presented. Standard annealing strategies are considered to activate the implanted dopants and repair the implantation damage in ...

Abstract Neochelys is an exclusively European Eocene podocnemidid genus belonging to a linage that reached this continent at the early Eocene. The so far available anatomical information about it is relatively abundant, especially considering that of its shell, at least partially preserved for the eight valid species currently considered.

The loss of teeth followed by bone resorption often lead to defects in the alveolar ridge, making installation of dental implants difficult. Correction of such bone defects, especially lack of height of the ridge, is a difficult problem for all dental ...

Calculation of the substitutional fraction of ion-implanted He in an Fe target [PDF]
Ion-implantation is a useful technique to study irradiation damage in nuclear materials. To study He effects in nuclear fusion conditions, He is co-implanted with damage ions to reproduce the correct He/dpa ratios in the desired or available depth range.

Five‐Year Results of One‐Piece Zirconia Oral Implants Supporting Three‐Unit Fixed Dental Prostheses
ABSTRACT Objectives The purpose of the present prospective case series was to investigate the clinical and radiological outcome of one‐piece zirconia implants fabricated from 3Y‐TZP with a moderately roughened endosseous surface (Sa = 1.24 μm) to support three‐unit fixed dental prostheses (FDP) after five years in function. Materials and Methods Twenty‐
