Exploring the compositional space of a metal–organic framework with ionic liqui...

The monitoring of atmospheric pollutants, especially non-methane-based volatile organic compounds (NMVOCs), is an important paradigm towards secure air quality surroundings. However, existing gas sensing technologies face challenges in selectively and sensitively detecting individual NMVOCs due to their low concentration in comparison to the main atmospheric components. In this research, the compositional space...

Temporary cement residues affect the bond strength and dentin penetration of se...

No. of bitstreams: 0 Previous issue date: 2021-01-01; This study evaluated the persistence of eugenol-containing (PR, Provy) or eugenol-free (RT, Relyx Temp, and TB, Temp Bond) temporary cement residues and its effects on push-out bond strength and dentinal penetration of the self-adhesive resin cement (Relyx U200). Eighty human roots were endodontically t...

Overview on thermoactive materials, simulations and applications

Thermoelectric (TE) materials have been attracting increasing interest once they are capable of directly convert temperature variations into electricity, being used in thermoelectric generators and thermoelectric sensor devices, among others. This work reports on the main principles of thermoelectric and thermomagnetic effects as well as the main materials used for the development of applications. Additionally,...

No. of bitstreams: 0 Previous issue date: 2020-01-01; Fondo Nacional de Desarrollo Científico y Tecnológico; Objective: This study assessed IL-1β and RANK-L levels in vivo and color stability of non-vital teeth bleached using hydrogen (35%) and carbamide (37%) peroxides 3 months after treatment. Materials and Methods: Fifty teeth were randomly divided into...

Design of ionic-liquid-based hybrid polymer materials with a magnetoactive and ...

Multifunctional materials with sensor and actuator capabilities are playing an increasing role in modern technology. In this scope, hybrid materials with magnetic sensing and electromechanical actuator response based on magnetic ionic liquids (MILs) and the polymer poly(vinylidene fluoride) (PVDF) have been developed. MILs comprising different cation alkyl chain lengths [Cnmim]+ and sharing the same anion [FeCl...

Effectiveness and effect of non-vital bleaching on the quality of life of patie...

Made available in DSpace on 2018-12-11T16:51:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-02-17; Objectives: The aim of this study was to evaluate the esthetic perception of patients at 6 months after bleaching of non-vital teeth with 35% of hydrogen peroxide and 37% of carbamide peroxide using a walking bleach technique. We also assessed psychosocial impacts as well as the clinical effectiveness a...

Quality of life and stability of tooth color change at three months after denta...

Made available in DSpace on 2018-12-11T16:55:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-01-01; Purpose: Intracoronary bleaching is a minimally invasive, alternative treatment that addresses aesthetic concerns related to non-vital teeth discoloration. However, to the best of our knowledge, no studies have assessed the psychosocial impacts of such procedures on patients’ aesthetic perceptions. The ...

Evaluación y clasificación en grupos empleando relaciones de preferencia borrosas

La presente propuesta trata el problema de obtener decisiones de consenso en grupo en situaciones de clasificación o evaluación, un tipo especial de problemas de clasificación multiparticipante donde se define una preferencia ordinal en el conjunto de categorías. Los problemas de clasificación y evaluación en grupo se transforman en un problema de ranking en grupo mucho más estudiado. Siguiendo las ideas de los...
