Dielectric behavior was compared experimentally between polyethylene terephthalate (PET) and poly(ethylene 2,6-naphthalate) (PEN). Due to their similar chemical structures, the two polymers exhibit many parallel dielectric properties. While the two polymers exhibit fairly similar thermally stimulated polarization and…
In this study, we performed optical visualization experiments on lightning impulse current discharge phenomena on carbon-fiber-reinforced plastic (CFRP) laminates. Lightning discharge is a phenomenon in which an extremely intense flash of light and heat is caused by a large electric current flow over a very short peri…
The paper considers 3D movable cellular automata (MCA) models of contact interactions involved in nanoindentation, sclerometry, and tribospectroscopy. The system under study is a titanium substrate with a harden coating. The substrate and coating materials are both described in the elastoplastic approximation. It is s…
Silicification is the replacement of original skeletal material accomplished through the concurrent dissolution of calcium carbonate and precipitation of silica. The processes is aided by the nucleation of silica to organic matter which surrounds the mineral crystallites within the shell. Factors that control silicifi…
The pairing and superfluid phenomena in a two-component ultracold atomic Fermi gas is an analogue of Cooper pairing and superconductivity in an electron system, in particular, the high T c superconductors. Owing to the various tunable parameters that have been made accessible experimentally in recent years, atomic Fer…
This paper presents the calculated demagnetization characteristics of different types of permanent magnet synchronous machines (PMSMs) under the influence of demagnetizing MMF contributed by the stator currents (i.e., armature reaction). The demagnetization of NdFeB magnets is quantified in terms of demagnetized magne…
Abstract Maraging steels are highly alloyed low-carbon iron-nickel martensite steels that possess an excellent combination of strength and toughness superior to that of most carbon-hardened steels. This article provides a detailed account of the formation of martensite in maraging steels. It discusses the heat treatme…
Neutron spectroscopy measurements of tritium beam transport at JET, Nocente, M., Albergante, M., Eriksson, J., Conroy, S., Ericsson, G., Farina, D., Hellesen, C., Källne, J., Popovichev, S., Tardocchi, M., Gorini, G., JET-EFDA contributors
Near-infrared dyes can be used as theranostic agents in cancer management, based on their optical imaging and localized hyperthermia capabilities. However, their clinical translatability is limited by issues such as photobleaching, short circulation times, and nonspecific biodistribution. Nanoconjugate formulations of…
An orthogonal self-assembled system consists of different structures which coexist independently. Furthermore, the characteristic properties of the respective "base systems", i.e. of the systems which contain only one of the structures, are retained in the orthogonal self-assembled system. We have identified gelled bi…
The results of studying the physical properties of thin CdTe films obtained by the thermal evaporation method have been presented. The optical constants and the band gap of the films under study have been determined (E g = 1.46 eV). It has been established based on the investigation of optical properties and the Raman…
Coffee bean (Coffea arabica) processing generates high amount of residues that are sources of environmental pollution. Therefore, an appropriate solution is needed. The objective of this study was to determine the potential of coffee pulp to produce briquettes and pellets. The study included pulp drying (using air, so…
The construction of heterojunction photocatalysts has received much attention in the field of photocatalytic H 2 production from water splitting. The surface phase junction of semiconductors is very important to the activity of heterojunction photocatalysts. In this study, an effective anatase–graphene–rutile heteroju…
The massive production of graphene by jet cavitation method with high productivity is demonstrated. Effects of the critical processing parameters on the product dispersions are studied systematically. Experimental results show that high yield of graphene flakes relies on appropriate initial concentration of graphite,…
ABSTRACT In this study, the effectiveness of free‐radical grafting as a compatibilization method applied to composites containing Kraft lignin (KL) and esterified lignin was comparatively investigated. Maleated lignin (ML) was first obtained via esterification of KL with maleic anhydride. KL and ML were respectively i…
Composite thermochromic and phase-change materials (CTPCM) containing bromocresolpurple, boric acid, and tetradecyl alcohol were prepared by sol–gel method. The thermochromic behavior and thermal properties of CTPCM were studied. The characterization of the CTPCM including the particle size, size distribution, FTIR sp…
Electrochemical aptasensors can detect different cancer biomarkers to provide point-of-care diagnosis that is low cost, rapid, specific and sensitive. In this work, we described the development of an electrochemical single-use aptasensor for detection and analysis of vascular endothelial growth factor (VEGF). Gold nan…
The new neutron spectrometer time-of-flight enhanced diagnostics (TOFED) for the EAST tokamak is presented and its characteristics are described in terms of simulation results, as well as the interface in the torus hall along with new neutral beam (NB) injectors. The use of TOFED for studies of the slowing down of NB-…
Self-heating in gallium nitride based high frequency, high electron mobility power transistors (GaN HEMTs) is inspected using micro-Raman thermography and 800 picosecond transient thermoreflectance imaging. The two methods provide complementary temperature information inside the semiconductor and on top metal layers o…
Epicocconone is a natural latent fluorophore that is widely used in biotechnology because of its large Stokes shift and lack of fluorescence in its unconjugated state. However, the low photostability and quantum yields of epicocconone have limited its wider use, and in the absence of a total synthesis, this limitation…
