The local electron power dissipation has been calculated in a field-effect nanowire transistor using a quantum transport formalism. Two different channel cross sections and optical and acoustic phonon mechanisms were considered. The phonon models used reproduce the phonon limited mobility in the cross sections studied…
Cell biomedical behavior is influenced by a number of factors, and the extracellular matrix (ECM) of the cellular microenvironment affects certain cancer cells. In the current study, U‑2OS cells were cultured on gold surfaces modified with different terminal chemical groups [methyl (‑CH3), amino (‑NH2), hydroxyl (‑OH)…
At keV energies, many electronic processes contribute to the emission of secondary electrons in the interaction of highly charged ions on surfaces. To unravel contributions resulting from isolated hollow atoms in front of the surface or embedded in the electron gas of the target, heavy highly charged Ar and Xe ions ar…
The solubilities and the refractive indices of the KCl-KBr-H 2 O system at 323.15 K were studied with the isothermal dissolution method. The phase diagram and refractive index diagram were plotted for this system at 323.15 K. There is only one crystallization field of the solid solution K(Cl, Br). The system belongs t…
XFe 2 O 4 magnetic nanoparticles (X = Mn, Fe, Co, Ni, and Zn) were prepared by using two methods: coprecipitation and hydrothermal. The synthesized nanoparticles were compared according to the separation in an external magnetic field and finally, the hydrothermal method was specified as a better synthesis method. The…
Abstract The aim of this study was to determine the adsorption capacity of the smectite clays (from the overburden of the lignite deposit in Belchatow) for two anionic dyes, i.e. Reactive Blue 81 (RB-81) and Direct Blue 74 (DB-74). Additionally, the influence of the thermal and chemical (acid and alkali) clay modifica…
Although numerous kinds of waterborne, nacre-mimetic films with excellent properties have been fabricated via different assembly methods, it remains difficult to put those kinds of lightweight materials into practical applications because they are sensitive to water in the environment. Herein, a simple superhydrophobi…
A novel reaction pathway to synthesize the linear trinuclear clusters [Fe 3 (CO) 5 (κ 2 -diphosphine)(μ-dithiolate) 2 ] via the direct reaction of the dinuclear hexacarbonyl precursor [Fe 2 (CO) 6 (μ-dithiolate)] with the mononuclear species [Fe(CO) 2 (κ 2 -diphosphine)(κ 2 -dithiolate)] has been developed with diphos…
Graphite moderator bricks used within many UK gas-cooled nuclear reactors undergo harsh temperature and radiation gradients. They cause changes in material properties of graphite over extended periods of time. Consequently, models have been developed in order to understand and predict the complex stresses formed withi…

The cation exchange capacity and saturation of the sorptive complex with base cations are very important indicators for quality assessment of soils, because they define soil fertility and resistance to chemical degradation. The objective of the following study was to estimate the cation exchange capacity and saturatio…
In this work, the Er 3+ :Y 3 Al 5 O 12 as up-conversion luminescence agent was mixed with TiO 2 and the corresponding Er 3+ :Y 3 Al 5 O 12 /TiO 2 composite films were prepared on the one-sided surface of treated sheet glass through sol-gel dip-coating method. The prepared Er 3+ :Y 3 Al 5 O 12 /TiO 2 composite films we…
The optical power distribution and the symmetry of the lens components are two important attributes that decide the ultimate lens performance and characteristics. Lens form parameters W and S are the key criteria describing the two attributes mentioned above. Lens components with smaller W and S will have a good natur…
Copper (Cu) nanofilms have been prepared on a molybdenum (Mo) substrate by the electrodeposition method from the electrolyte solutions of copper sulfate (CuSO 4 ) and trisodium citrate (C 6 H 5 Na 3 O 7 ) added by surfactant PEG-6000. The growth kinetics and microstructures of films were investigated by cyclic voltamm…
We synthesized novel liquid crystalline semiconductors bearing an extended π-conjugated mesogen based on thieno[3,2-b]thiophene, which exhibit high solubility and low phase transition temperature. In particular, lateral methyl substitution to the mesogenic unit led to the formation of efficiently self-organized LC dom…
The current paper addresses the thermal characterisation of Miscibility Gap Alloys (MGAs). These novel materials combine two immiscible metallic phases with different melting temperatures. The fusible phase (i.e. the phase with a lower melting temperature) acts as a phase change material that stores latent heat (in ad…
Abstract Polyester fabric was treated with polyvinyl alcohol in alkaline medium. The moisture regain, water retention and wettability of the PVA treated polyester fabric were tested. The PVA treated PET fabric was dyed with disperse dye. The presence of PVA in the treated PET fabric was assessed by spot test. The trea…
To enable Cu fill of through-Si vias (TSV) with a high aspect ratio (diameter 3 μm, depth 50 μm), the electroless deposition of a Cu seed on Co liner material was investigated. The reducing agent glyoxylic acid showed anodic oxidation on Co, which did not appear for the case of formaldehyde. From electrochemical analy…
Advanced computational methods allow sampling of rare events and reveal multiple pathways in melting of metals [Also see Report by Samanta et al. ]
Acetonitrile solutions of nickel(II) acetylacetonate, which is ubiquitously used in different fields of organometallic chemistry and catalysis, were investigated by means of electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry (MS/MS). The detected Ni 2 (acac) 3 + ion with the binuclear Ni 2…
