The external beam line of the Laboratory for Material Analysis with Ion Beams (LAMFI) is a versatile setup for multi-technique analysis. X-ray detectors for Particle Induced X-rays Emission (PIXE) measurements, a Gamma-ray detector for Particle Induced Gamma- ray Emission (PIGE), and a particle detector for scattering…
In this study, a non-commercial ceramic compound with high corrosion resistance based on Na2O, Al2O3, SiO2, K2O, CaO, TiO2, FeO and others, was developed and stabilized in an aqueous media. The enamel coatings were developed over stainless steel 316L at 7.5 V and 30, 60 and 90 secounds by electrophoretic deposition te…
Capacitance measurements were made on an array of parallel ZnO nanowires embedded in a polymer matrix and provided with two electrodes perpendicular to the nanowires. The capacitance monotonically increased, and saturated at large negative (depleting) and large positive (accumulating) voltages. A qualitative explanati…
Abstract This paper focuses on the dislocation configurations that show up during the annihilation of a perfect dislocation vacancy dipole. Indeed unexpected transient dislocation core structures can be evidenced out of the atomistic structures computed during this annihilation process. Using the Geometric Phase Analy…
The recent progress in nanocomposites and nanomaterials is varied and occupies various fields. Nanocomposites can be prepared with a variety of special physical, thermal, and other unique properties. On the other hand, self-assembly technique is playing an important role in preparing well-defined multilevel nanostruct…

The 292 papers are grouped as follows: Chapter 1: Additive Manufacturing Research;Chapter 2: Advances in Mechanics; Chapter 3: Fluid Mechanic and Heat Transfer;Ch…
新潟県糸魚川市中央部には，日本を代表する構造線の一つである糸魚川-静岡構造線が存在し，その西側には，西南日本を構成する地帯の構成岩が狭い範囲に分布する．その中の蓮華変成岩類と超苦鉄質岩からなる蓮華帯は，古生代に東アジアの大陸縁辺部の沈み込み帯で形成されたとされている．その後，飛騨変成岩類や飛騨花崗岩類などからなる大陸地域とペルム紀やジュラ紀付加体との間で生じた造構作用によって，蓮華帯は両者間に位置するようになり，その造構作用に伴って形成された地質体を保持している．これらの地質体を解析することは，上記の造構作用の実態を明らかにする上で重要である．●本コースでは，まず2015年3月にリニューアルしたフォッサマグナミュージアムで，見学コ…
Nach dem Lesen nicht vernichten: Die Entwicklung eines Diarylbenzobis(thiadiazol)-Derivats mit thermisch schaltbaren Isomeren, die wegen des hohen sterischen Anspruchs einzeln isoliert werden können, stellt einen wichtigen Fortschritt in der Datenverarbeitung mit photochromen Verbindungen dar. Damit stehen photochrome…
The authors conduct an experimental study of the dynamics of secondary (diffusely scattered and fluorescent) X‐ray radiation originating from the moving grains of minerals and offer a semi‐quantitative explanation for it. They compare the secondary radiation's amplitudes for the free falling grains of natural diamond…
Composite coatings based on PEEK and Lignin were obtained by EPD. The addition of Lignin had some beneficial effects, the most relevant being an increased coating adhesion on conductive substrates. Before using in EPD suspensions, Lignin was functionalised by a carbonyl group. This functionalisation produced chemical…
Bilayered magnetic films (Co50Fe50 (CoFe)/Metglas) were RF sputtered on both (001)-oriented and (011)-oriented PMN-PT (lead magnesium niobate-lead titanate) substrates. Electric field-controlled magnetization changes were observed in all these samples: 65 nm CoFe/24 nm Metglas/(001) PMN-PT, 65 nm CoFe/24 nm Metglas/(0…
The thermal energy storage material, namely hexadecyl ammonium tetrachloro cadmate (n-C16H33NH3)2CdCl4, which belongs to the organic–inorganic hybrid layered compounds, was synthesized as an example of long-chain complexes of the series (n-CnH2n+1NH3)2CdCl4 (n = 8–18). The ac conductivity σac(ω, T) and the complex die…
Carbon nanotubes (CNTs) and graphene hold a great promise for the development of miniaturized chemical sensors because of (1) greater adsorptive capacity due to large surface area to volume ratio, (2) better modulation of electrical properties (e.g., capacitance and resistance) upon exposure to analytes due to a great…
We present a theoretical framework for evaluating effective interactions between localized spins mediated by itinerant electrons in double-exchange models. Performing the expansion with respect to the spin-dependent part of the electron hopping terms, we show a systematic way of constructing the effective spin model i…
45S5 bioactive glass (BG) based multilayer coatings on stainless steel were produced by a combination of electrophoretic deposition (EPD) and layer-by-layer (LbL) deposition. The properties of the multilayer coating were tested with different characterization methods including SEM, FTIR, XRD, laser profilometer and wa…
Electrophoretic deposition of ligand-free platinum nanoparticles has been studied to elucidate how wettability, indicated by contact angle measurements, is linked to vital parameters of the electrophoretic deposition process. These parameters, namely the colloid concentration, electric field strength and deposition ti…
Quality by design (QbD) is a risk management and science-based approach laid down by the ICH as well as other Regulatory agencies to enhance pharmaceutical development throughout a product’s lifecycle. Poly(lactide-co-glycolic acid) (PLGA) is the material of choice for development of depot particulate formulations due…
The individual noble metal nanoparticles (NPs) are combined to form alloys with improved optical response, cost effectiveness and better stability. The selection of noble metal alloy NPs for their better use in plasmonic applications is being made on the bases of surface plasmon resonance peak position, its intensity…
Current study focuses on the exploration of Saccharum spontaneum to fabricate polymer green composite in polypropylene matrix with malic anhydride-grafted compatibilizer. Analysis by thermogravimetric showed slight deviation in thermal stability only at higher kans grass-filler loading, but significant improvement was…
Yersinia enterocolitica is a Gram-negative bacterium that causes yersiniosis, a zoonotic disease affecting the gastrointestinal tract of humans, cattle, and pigs, among others. The lipopolysaccharide of Y. enterocolitica O:8 contains an unusual sugar, 6-deoxy-d-gulose, which requires four enzymes for its biosynthesis.…
