The aim of this work was to reduce microleakage in giomer restorations by using innovative materials in both adhesive systems and light-cured dental giomer. Two adhesive systems with different primers were investigated. The innovative compounds in the primers were acrylic acid (AA)/itaconic acid (IA) copolymer modified with methacrylic groups and AA/IA/N-acryloyl-L-leucine copolymer grafted with methacrylic groups. In addition, the investigated new giomer G contains a pre-reacted glass based on the latter copolymer. The commercial Beautifil II giomer and the FL-Bond II adhesive system were used for comparison. Microleakage was evaluated by determining the scores and percentages of dye penetration lengths after thermocycling of a series of light-cured dental giomer restorations performed on 42 premolars extracted for orthodontic reasons. A lower microleakage value was recorded for the adhesive system containing the AA/IA/N-acryloyl-L-leucine copolymer grafted with methacrylic groups than for the commercial adhesive, which was in substantial agreement with SEM and AFM investigations. In this case, remarkable dentin sealing and a strong adhesion at the giomer restoration�tooth interface was observed, and the innovative adhesive was proven to be promising for dental applications.

In a recent companion paper, a three-dimensional isotropic elastic micromechanical framework was developed to predict the mechanical behaviors of the innovative asphalt patching materials reinforced with a high-toughness, low-viscosity nanomolecular resin, dicyclopentadiene (DCPD), under the splitting tension test (ASTM D6931). By taking advantage of the previously proposed isotropic elastic-damage framework and considering the plastic behaviors of asphalt mastic, a class of elasto-damage-plastic model, based on a continuum thermodynamic framework, is proposed within an initial elastic strain energy-based formulation to predict the behaviors of the innovative materials more accurately. Specifically, the governing damage evolution is characterized through the effective stress concept in conjunction with the hypothesis of strain equivalence; the plastic flow is introduced by means of an additive split of the stress tensor. Corresponding computational algorithms are implemented into three-dimensional finite elements numerical simulations, and the outcomes are systemically compared with suitably designed experimental results.

Metalloporphyrins (MP) and metallophtalocyanines (MPc) are innovative materials with catalytic properties that have attracted attention for their application for diverse electrochemical purposes. The presence of metallic centers in their structure offers a redox-active behavior that is being applied in the design of solid electrodes for the quantification of biomolecules, water contaminants, and pharmaceuticals, among others. Herein, we collect the recent information about porphyrin and phthalocyanine complexes as modifiers of electrodes, and the important aspects of the design, characterization, and application of these electrodes.
