We have fabricated multi-stacked InGaAs/AlGaAs quantum dot (QD) solar cells on GaAs (311)B substrate in order to clarify the structural, optical, and electrical properties of QDs which exhibit superior in-plane spatial ordering and the effect of a large energy band offset using AlGaAs matrix layer. It was confirmed th…
Indentation-flattening compound deformation technology (IFCDT) is defined, and the characteristics of IFCDT are discussed. Microstructure evolution of dynamic recrystallisation of AZ31 magnesium alloy during IFCDT was simulated by cellular automaton method (CA). Dynamic recrystallisation of AZ31 magnesium alloy deform…
Organic-inorganic hybrid perovskites are attracting intense research effort due to their impressive performance in solar cells. Carrier recombination at defects is detrimental to the device performance. While the bulk carrier parameters in the perovskites such as mobility and bulk carrier lifetime show sufficient char…
The existence of small amount of retained austenite in precipitation hardening stainless steels (PHSS) is known to be effective to improve the ductility caused by transformation-induced plasticity. However, the detailed mechanism is yet inadequately understood. In the present study, two types of PHSS are prepared and…
Fine spherical glass particles on a Si substrate were removed using the adhesive force between them and a polyethylene (PE) film or polyurethane (PU) rubber sheet. The PE film or PU rubber sheet was placed on the Si substrate on which spherical glass particles with a diameter of 0.3–1.5 μm were adhered. The film/sheet…
The vertical-cavity surface-emitting laser (VCSEL) is a well-established light source for sensing and short-reach optical links. The surface emission allows wafer-scale testing enabling low-cost manufacturing, while the VCSELs’ small modal volume leads to low power consumption, high-speed modulation at small currents,…
The behavior of the fracture processes of a metal nanostructure under deformation in the temperature range 0-550 K was investigated by the molecular dynamics method. An ideal copper crystal was used as a sample in the form of a rectangular parallelepiped with the number of crystalline cells nx = 50, ny = nz = 5 along…

We show that octylamine-modified poly-(acrylic acid) is adopted to wrap hydrophobic upconversion nanoparticles (UCNPs), and the UCNPs are further biofunctionalized and applied to integrate luminescence imaging with optical tweezers for detecting microRNA-21 sequences.
Determination of the natural radionuclide contents of soil and rock samples collected from some mountains and valleys in Sinai, Egypt, has been carried out using gamma spectrometric techniques. The total average concentrations of radionuclides 226Ra, 238U, 232Th, and 40K were (51.37, 50.02, 19.34, and 286.66 Bq/kg), r…
In this thesis, the interactions between MoS2 and dysprosium have been investigated by spectroscopic and diffractive techniques. As the experimental research on dysprosium compounds is scarce, the possible applications of these could be many. Depending on the stoichiometry of the compound, it may contribute in fields…

Computational results on the external surface structure of ZIF-8
Serial femtosecond crystallography is the process for which an ultrafast free-electron x-ray laser diffracts a protein crystal into its atomic structural basis. From these atomic structures, scientists can better understand the functions of the diffracted proteins. This is important because the protein structures obta…
Shape memory alloys (SMAs) are materials that show reversible, thermo-elastic, diffusionless, displacive (solid to solid) phase transformation, due to the application of temperature and/ or stress (/strain). Among different SMAs, NiTi is a popular one. NiTi shows reversible phase transformation, the shape memory effec…

High prevalence and mortality cases of prostate cancer (PCa) have increased around the world, particularly in developing countries. Several forthcoming factors have been revealed nowadays, one of them is due to the incapability of the diagnostic methods to produce reliable results, which impacts negatively on cancer-t…

Changes in the surface microgeometry of multilayer graphene films, as a result of hydrogen adsorption (1% mass.), have been examined by the method of low-temperature fractal sorption of nitrogen. It is established that hydrogen atmosphere treatment leads to the significant development of graphene surface and lowers th…
