Magnetic resonance imaging (MRI) is one of the most important tools in clinical diagnostic and biological research. Lately, the development of 19F based MRI methods has been receiving increased attention due to its ability to overcome specific drawbacks associated with standard 1H MRI techniques. When combined, 1H and…
Three-dimensional (3D) biodegradable composite porous scaffolds made of a biopolymer matrix (chitosan) and a bioactive glass (FastOs®BG-Z4) were fabricated via freeze drying as guides for nerve tissue engineering applications. For this purpose, chitosan was dissolved in aqueous solutions of lactic acid (LA, 1 wt.%) to…
SnS is of interest for use as an absorber layer and the wider energy bandgap phases e.g. SnS2, Sn2S3 and Sn/S/O alloys of interest as Cd-free buffer layers for use in thin film solar cells. In this work thin films of tinsulphide have been thermally evaporated onto sodaÂÂlime glass substrates with the aim of optimisin…
The public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of informat…
Il lavoro di ricerca di dottorato ha avuto come oggetto lo sviluppo di un sistema di analisi integrato (in vivo e in vitro) basato su modelli eucariotici (lievito e piante superiori) che ha consentito di studiare fenomeni di tossicità e resistenza nei confronti di nanomateriali importanti dal punto di vista ambientale…
The aim of this research project was to develop new structural materials from the paper plastic laminate (PPL) waste stream. PPLs containing both paper fibre and plastic coatings are problematic for non-thermal recycling options. The current end of life disposal for PPL is primarily landfill. This work focuses on comb…
Various excipients are used in the pharmaceutical tablet industries to present desirable properties in the final product. All excipients should have suitable flowability to produce homogenous distribution at the point of mixing. In addition, the excipients have to be hydrophilic as a disintegrant, have proper compacti…
東京電力は、2号機原子炉建屋5階のオペレーティングフロアからの燃料取り出し準備として遮へい・除染計画を立案するため、当該フロアの状況調査を行い、空間線量率が数十mSv/hから数百mSv/hであることをロボットで確認しているが、汚染部位計測には至っていない。そこで、原子力機構は自ら開発したガンマカメラであるgamma-eyeIIの汚染部位計測への適用性を事前に確認したうえで、当該フロアの詳細な汚染分布や汚染密度の情報収集を実施した。事前確認の結果、gamma-eyeIIが比較的高い空間線量率環境下にあっても、当該フロアに想定された高い汚染部位を計測可能であることを確認した。そして当該フロアの汚染部位計測の結果、調査範囲の主たる汚染源…

The ground state of twist-bend nematic liquid crystals is a heliconical molecular arrangement in which the nematic director precesses uniformly about an axis, making a fixed angle with it. Both precession senses are allowed in the ground state of these phases. When one of the two \emph{helicities} is prescribed, a sin…
Στα πλαίσια της διδακτορικής διατριβής πραγματοποιήθηκε η σύνθεση και οφυσικοχημικός 65 νέων συμπλόκων ενώσεων και μελετήθηκε η βιολογική συμπεριφορά τόσοτων ελεύθερων ligands όσο και των συμπλόκων ενώσεων του Zn(ΙΙ), Cu(ΙΙ) και Mn(ΙΙ) ήMn(III), με κινολόνες πρώτης, δεύτερης, τρίτης και τέταρτης γενιάς, με ΜΣΑΦ της τά…
Peculiarities of the behavior of some optical characteristics of orientationally ordered wall-adjacent layers of nonmesogenic liquids – epitropic liquid crystals (ELC) – are analyzed. A suggested model develops the well-known Maier–Saupe–Neugebauer theory and takes a two-component structure of ELC (dynamic equilibrium…
L'encapsulation de principes actifs, qu'elle soit permanente ou à relargage contrôlé, a des applications dans des domaines aussi variés que la pharmacie, l'agrochimie, l'alimentaire, la cosmétique, le textile, le bâtiment. Cet article décrit comment à partir d'une problématique propre au domaine de la cosmétique, qu'e…
Vous avez des difficultés de soudage avec des thermoplastiques ? La géométrie du plan de joint est complexe et les matériaux sont fragiles ? Cette fiche vous permettra de découvrir et maîtriser les spécificités du soudage à gaz chaud (azote) des thermoplastiques.
This paper delves into the abnormal surface diffusion of particles in external time-periodic field. The relationship of surface diffusion enhancement as a function of amplitude and frequency of external fields has been studied. It has been shown that the diffusion coefficient can significantly be increased (by several…
What's your bike made from, steel, titanium, carbon fibre? How about wood? It's the newest, oldest bicycle building material.
Aura Energy Ltd managing director Bob Beeson has every reason to be optimistic about the future of uranium if recent analytical commentary holds true.
Plastik ürünlerin üretilmeden önce analizinin yapılarak değerlendirilmesi üreticiler için pek çok kazanç sağlamaktadır. Bu çalışmada da günlük hayatta sıklıkla kullanılan plastik bir bardağın baskı analizi bilgisayar destekli programla (Autodesk Moldflow) yapılmıştır. Analiz için 16oz büyüklüğündeki bir bardak çizilmi…
The interfacial electronic structure of the organic material- tris(8-hydroxyquinolinato)aluminum (Alq3) forming an interface with cobalt metal has been investigated in this research. The primary characterization method used in this research was near-edge X-ray absorption fine structure (NEXAFS) spectroscopy which prob…
For the past decades, researchers indicate that persistent scaling of conventional silicon Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) reaching its physical limit at 10nm, resulted in its performance degradation as the search continues for a low-power and high speed, density and reliability devices. The…
