1. On Estimation of Adhesive Strength of Implants Bioactive Coating with Titanium by Density Functional Theory and Molecular Dynamics Simulations
One of the ways to improve and accelerate osseointegration of a surgical implant with bone is application of biocompatible coatings, in particular, hydroxyapatite (HAp). Since the cases of delamination of the coating take place in dental practice, it is very important to estimate the adhesive strength of HAp with the implant. A measure of the coating-to-subs

2. A New Phe-Free Protein Substitute Engineered to Allow a Physiological Absorption of Free Amino Acids for Phenylketonuria
Abstract An innovative technology (Physiomimic Technology) has been applied to amino acids (AAs) formulated for patients with phenylketonuria, with the objective of masking AA taste and odor and prolonging AA release in the gut, allowing a physiological absorption. This technology entails that the AAs are processed with functional additives that are able to

3. Thermal Spraying Processes and Amorphous Alloys: Macro-Indicators of Patent Activity
Thermal spraying processes allows high cooling rates and can favor the formation of amorphous microstructures. Amorphous metallic coatings can result in superior mechanical and functional properties. To follow new technological development and innovation paths, indicators based on patent data can be assembled to support technological forecasting assessments

4. Microencapsulation of plum (Prunus salicina Lindl.) phenolics by spray drying technology and storage stability
Abstract To improve the stability of the phenolic extracts from plum fruit (Prunus salicina Lindl.), the microencapsulation conditions of spray drying were optimized by the response surface method. The Box-Behnken experimental results indicated the optimal conditions involved an inlet air temperature of 142.8 °C, a core material content of 23.7% and a feed

5. Analysis of Compositional Modification of Commercial Aluminum Bronzes to Obtain Functional Shape Memory Properties
In copper-based shape memory alloys (SMAs), some exceptional phenomena, such as the shape memory effect (SME) or superelasticity (SE), are observable. However, commercial aluminum bronzes, Cu3Al-based alloys, do not present these functional properties (SME and/or SE) in their original state. Thus, since one of the main copper-based SMA systems is the Cu-Al-N

6. Hybrid Self-Assembled Materials Constituted by Ferromagnetic Nanoparticles and Tannic Acid: a Theoretical and Experimental Investigation
Hybrid magnetite materials are interesting for both biomedical and catalytic applications due to their well-known biocompatibility, as well as their magnetic and electric properties. In this work we prepared Fe3O4 nanoparticles (NPs) coated with tannic acid (TA), a natural polyphenol, through two different synthetic routes, aiming to understand the influence

7. An experimental simulation model for coated paper drying
Due to the lack of information regarding the phenomena of mass, heat, and momentum transfer in coated paper drying, substantial research work still needs to be done. A simulation model for coated paper drying is introduced which integrates heat and mass transfer mechanisms. In the model, the coated paper was assumed to have 3 layers (coated layer, wet and dr

8. Crosslinkable potato starch-based graft copolymer emulsion for humidity controlling coatings
A new kind of crosslinkable potato starch-based graft copolymer emulsion (PoSt-g-BMD) has been prepared using butyl acrylate (BA) and methyl methacrylate (MMA) as main monomers, and diacetone acrylamide (DAAM) as functional monomer. The keto-carbonyl group of DAAM in PoSt-g-BMD copolymer could react with adipic dihydrazide (ADH) at ambient temperature to for

9. Electrical conductivity and thermal properties of functionalized carbon nanotubes/polyurethane composites
Multi-walled carbon nanotubes (MWCNTs) functionalized with amine and carboxyl groups were used to prepare polyurethane/MWCNT nanocomposites in two distinct concentrations: a lower value of 1 mass% (spray coating) and a higher one of ~50 mass% (buckypaper based). The MWCNT-NH2 sample contained only 0.5 mass% of amine groups, whereas MWCNT-COOH contained 5 mas

10. UTILIZAÇÃO DO AGREGADO SIDERÚRGICO (ESCÓRIA DE ACIARIA) EM REVESTIMENTO ASFÁLTICO TIPO TRATAMENTO SUPERFICIAL / UTILIZAÇÃO DO AGREGADO SIDERÚRGICO (ESCÓRIA DE ACIARIA) EM REVESTIMENTO ASFÁLTICO TIPO TRATAMENTO SUPERFICIAL
Environmental sustainability requires preventive or mitigating environmental impacts caused by industrial production activities, to preserve non-renewable mineral resources. In this sense, this work is to evaluate through experimental studies predominantly by laboratory testing and field application the use of steel slag produced by Arcelor Mittal Tubarão i

11. PREPARAÇÃO, CARACTERIZAÇÃO E ESTUDOS ELETROQUÍMICOS DE ELETRODOS MODIFICADOS COM DIFERENTES MONOCAMADAS AUTOORGANIZADAS
In this work were studied investigated different types of modifiers for the formation of self-assembled monolayers on the gold surface. The monolayers used were formed by different structural arrangements, alkyl chains and functional groups. The thiols groups used were: 3-mercaptopropionic acid (MPA), thiolactic acid (TLA), cystamine (CYS) and 11-mercaptound

12. Revestimento ativo enriquecido com aminoácidos em feijão-comum / Active coating enriched with amino acids in common bean
Beans is one the most consumed legumes in developing countries. However, this food is also consumed in developed countries, although in small amounts. Bean is the third legume more important of world. The parameters that confer the bean its technological and nutritional quality are related with genetic variation, and environmental and their interaction. The
