Previous theoretical reports have described the oxidation of few-layer black phosphorus and its effects on the electronic properties. Theoretically, native oxide layers bring opportunities for band gap engineering, but the detection of the different types of oxides is still a challenge at the experimental level. In this work, we uncover a correlation between thermal processes and Raman shift for the A g 1 , B 2g , and A g 2 vibrational modes. The thermal expansion coefficients (temperature range, 290–485 K) for the A g 1 , B 2g , and A g 2 were −0.015, −0.027, and −0.028 cm –1 K –1 , respectively. Differential scanning calorimetry analysis shows an endothermic process centered at 528 K, and it was related with a mass increase according to thermogravimetric analysis. Raman shift temperature dependence was correlated to theoretical lattice thermal expansion, and a significant deviation was detected in the stacking direction at 500 K.

Nanostructured composite dispersions containing magnetic nanoparticles (MNPs) and graphene oxide (GO) lamellae have been prepared by a simple and easily scalable room temperature procedure. We show that, owing to the enormous surface area and negative surface charge developed in aqueous GO suspensions, large amounts of positively charged MNPs can be electrostatically attached to the layered host. is procedure is superior to many previous synthesis pathways because it exploits the chargeregulated adhesion of naked MNPs to GO resulting in the formation of stable and uniform nanocomposite materials in a wide composition range without any preliminary functionalization steps or harsh conditions that may lead to chemical degradation of the graphene-based nanosheets.

Jelen összefoglaló mű célja, hogy útmutatót adjon az epidermolysis bullosa mindennapi ellátásában, a betegek orális egészségének és ezen keresztül életminőségük színvonalának emelésében, valamint támogassa a magyar általános orvosok, bőrgyógyászok és a fogorvosok közötti kooperációt. A nemzetközi irodalom alapján segítséget szeretnénk nyújtani abban, hogy a beteget gondozó bőrgyógyász vagy a háziorvos mikor vonjon be szájüreggel foglalkozó szakembert, illetve a fogorvosnak, hogy milyen fő prevenciós vagy azon túlmutató teendői vannak. A fogorvosi kezelés különböző aspektusain keresztül bemutatjuk, hogy egy fogorvos milyen módon láthatja el a pácienseket további sebek vagy fájdalom okozása nélkül, valamint milyen beavatkozásokat és hogyan tud számukra megvalósítani.

Kulcsszavak: epidermolysis bullosa, fogászat, orális egészség, útmutató, terápia Epidermolysis bullosa: oral manifestations and their treatmentsThe aim of this comprehensive article is to provide guidelines for the daily treatment of patients with epidermolysis bullosa, thus contributing to the attainment of their higher quality of life through the improvement of their oral health. Moreover, it is our intention to facilitate the cooperation among Hungarian general practitioners, dermatologists and dentists. Relying on recent research findings of the international literature, we intend to help general practitioners or dermatologists treating epidermolysis bullosa patients on a daily basis by identifying symptoms that require consulting an oral professional on the one hand, and to present the most important prevention strategies and further treatments advised for dentists on the other. Focusing on various aspects of dental treatment, we specify how a dentist can treat the patient without causing additional wounds or pain, and what kinds of therapy are justified by this approach. Rövidítések DDEB = domináns dystrophiás epidermolysis bullosa; DEB = dystrophiás epidermolysis bullosa; DMF = (decayed, missing, filled) szuvas, hiányzó, tömött; EB = epidermolysis bullosa; EBS = epidermolysis bullosa simplex; IgA = immunglobulin-A; JEB = junctionalis epidermolysis bullosa; RDEB = recesszív dys trophiás epidermolysis bullosa Az epidermolysis bullosa (EB) ritka örökletes bőrbeteg-ség, amely a bőrön és nyálkahártyafelszíneken akár kisebb mechanikai behatásra is hólyagképződéshez vezethet. A hámban, illetve a hám-kötőszöveti határon, a basalis membrán zónaterületén alakul ki szétválás a struktúrfehérjék defektusa, esetleg teljes hiánya miatt.

Resin based composite restorative materials and their effect on oral and general health Literature reviewIn dentistry, more and more new materials are becoming commercially available to facilitate a more perfect healing activity. It has to be realized that beyond their restorative function in the tooth or in the oral cavity by themselves, these materials are also placed into a dinamically changing medium, thereby they interact not only with their direct environment, but with the whole organism. Keeping this in mind, it is mandatory to know not only about their properties and handling, but also their local and systematic effects in order to minimize or avoid the potential harmful impact on the tissues or on the whole body. The authors with this review would like to give an insight, a small guideline for the daily use of resin based materials, based on the international and Hungarian scientific literature data. The goal is, besides reinforcing our knowledge, to create a safer conditions and environment for the patient, the dentist, and the whole medical team during treatment for the patient, the dentist, and the whole medical team.
