Abstract

The development of new diamond based bio-mechanically active hybrid nano-structured scaffolds for cartilage cells tissue engineering are proposed in this study. Innovative tissue engineering biomimetic materials based on hydrogel have shown attractive physical, biological and mechanical properties in several biomedical applications. A highly biocompatible novel hybrid material based on nanodiamonds and hydrophilic poly-(hydroxyl-ethyl-methacrylate) (pHEMA) is proposed. The aim of this paper is to describe the chemical and analytical procedures for the preparation of nanofilled hybrid composites possessing biomimetic, osteoconductive and osteoinductivity properties that can be useful in the design of bio-mechanically active innovative bone scaffolding systems for stem cell differentiation and growth. A more rigid and rubber transparent hybrid nano-composites are predicted to posses improved mechanical strength overwhelming one of the major weaknesses of hydrogels, which is due their poor mechanical characteristics, for applications in biomedical structural application.

Abstract

Homeopathy or homoeopathy (from the Greek hómoios, “similar” and páthos, “suffering” or “disease”) is a science created by Samuel Hahnemann in 1796. The homeopathic practice rests on three principles: The similarity, the individualization of cases and the infinitesimal. The use of the infinitesimal was proposed by Hahnemann in the early nineteenth century with the publication of “Organon der Heilkunst” (Organon of the art of healing). The compounds used do not become homeopathic unless they respect the principle of similarity, according to which a patient should be treated with a substance producing experimentally in a healthy person symptoms similar to those presented by the affected person, use of the substance being adapted to the patient thanks to the principle of individualization according to which the homeopath analyzes all the symptoms of the person and not only those related to the disease. Substances chosen according to this method can be administered in non-toxic weighted doses, but most prescribers use them in dilutions, sometimes very large, which have previously been subjected to very high and very frequent vibrations. Although some clinical trials produce positive results, multiple systematic reviews indicate that this is due to chance, questionable research methods, or publication biases. Despite a certain popularity, the therapeutic efficacy of homeopathy has not been demonstrated as a general and permanent solution. The vast majority of the scientific and medical community considers that homeopathy is a pseudo-science coming into contradiction with current knowledge in chemistry and biology established after the fundamental principles of homeopathy themselves proposed more than two Centuries. In particular, they point out that certain homeopathic dilutions are such that the excipient no longer contains a single molecule of the diluted remedy and therefore can’t act chemically. Moreover, the fact that effects are observed is disputed by published meta-analyzes which conclude that homeopathy has not demonstrated its clinical efficacy beyond the placebo effect and yet, the Homeopathy works, despite some malicious feedback.

Abstract

The implementation of the Ion Plating Plasma Assisted technology in the area of surface functionalization for structural color and relic preservation applications is presented. Interferometric structural colors on irregular bumped Titanium surfaces and transparent and achromatic nano films on ancient ceramic artifact have been investigated. Titanium metal and ceramic supports have been utilized for the surface functionalization tests: A metallic electron beam additive manufactured Titanium component and an ancient tile of the XIX century, which was characterized by strong chromatic valence and by a mixed porous and glazed surfaces, have been considered. A reactive magnetron sputtering Ion Plating Plasma Assisted apparatus operating in Argon or Oxygen atmospheres for TiO2 and SiO2 deposition has been utilized. Preliminary tests with two plasma treatments were carried out for optimal processing conditions definition. TiO2 nano-film deposition on irregular Ti surfaces has generated light direction depending color-changing surfaces while good achromatic and transparent coatings were obtained by using SiO2 coating. The high processing flexibility of the Ion plating technology is discussed. The SiO2 IPPA surfaces treatment resulted more convenient for restorative and preservation ancient historical tile was used to finally test the optimized process with Ion Beam Electron Microscopy, which was carried out on the tile porous structure, confirmed the high flexibility and efficiency of the innovative IPPA technology.

Abstract

Hydrogen is the number 1 element in the Mendeleev table, which is practically the smallest known element. From an energy point of view, hydrogen is of particular importance, being the key element for obtaining renewable and sustainable energy, either in the form of nuclear fusion energy or as a supportive element of nuclear fission energy by enriching its fuel or by burning it in thermal burners, or thermal or external combustion engines. Hydrogen, together with oxygen and with nitrogen and phosphorus are the four vital elements, which together make up the ATP energy molecule that donates the energy of living matter at the cellular scale. That is why we considered it necessary to study several structural aspects of nuclear hydrogen in the presented paper. The dimensions and shape of the existing hydrogen nuclei will be analyzed for the purpose of their description as accurately as possible, given that the dimensions of a particular type of hydrogen nucleus are not constant, varying dynamically depending on the linear displacement speed of the nucleus. The paper examines only the three isotopic forms of nuclear hydrogen, known as relatively stable, the first completely stable and the next two relatively stable. From the fourth isotopic form up, the stability is almost inexistent, the life of such an isotope being ephemeral, which is why we did not consider it necessary to study these ephemeral forms of existence of hydrogen isotopes equal to or greater than four. The immediate applications of the theory presented are the obtaining of fusion energy, industrial. • Dimensions and shape of the existing hydrogen nuclei. • Dimensions of a particular type of hydrogen nucleus are not constant, varying dynamically depending on the linear displacement speed of the nucleus. • Paper examines only the three isotopic forms of nuclear hydrogen, known as relatively stable. • Immediate applications of the theory presented are the obtaining of fusion energy, industrial.
