Chalcogenide glasses of (Se90Te10)100-x Inx (x = 0, 3, 6, 9, 11) alloys are prepared by melt quench technique.
Differential scanning calorimetry (DSC) technique with different heating rate is used to study the dependence of
the glass transition temperature (Tg) and fragility dynamics m on the In content in the Se-Te matrix. It is
observed an increase of Tg with increasing In content. The glass transition temperature is differently defined
according to the different degree of conversion of the glass. The activation energy of the glass transition (Eg) is
evaluated using Kissinger, Moynihan kinetic and the partial area (isoconversional) methods. Analysis of experimental data shows that Eg changes with the degree of conversion from the glassy to the supercooled phase.
The variation of the fragility with indium content is attributed to the formation of network structure. The
employed theoretical models to describe the kinetics of the glass transition are valid

Chalcogenide Se90Sb10 thin films are deposited by thermal evaporation from the bulk alloy. X-ray diffraction
examination for the annealed films shows the amorphous-crystalline transformation. This is beneficial for optical
disk data storage technology. The crystallinity is improved by increasing the annealing temperature. The films
annealed at relatively low temperatures exhibit highly transparence reaching to about 90% at incident light of
wavelength of 900 nm. The as-prepared and annealed Se90Sb10 films reveal an indirect allowed optical transition. The annealed film at 473 K has an optical band gap of 1.676 eV which is suitable value for solar cell as
photovoltaic application. Both the indirect optical energy band gap (Eg) and the oscillator energy (Eo) decrease
whereas the oscillator strength (Ed) increases with increasing the annealing temperature. The annealing increases the conductivity and decreases the activation energy for conduction resulting in enhancement of film
properties for adapting to solar cells

The Japanese government has recently set an ambitious
target to reduce its CO2 emissions by expanding renewables
and nuclear power plants (NPPs). Perception of nuclear
power, however, has always been an issue in Japan. This
research reports the results of a survey regarding public
acceptance of NPPs in three community groups and
associations with some of its influencing factors. The
samples are taken from one site near a plant under
construction (Kaminoseki), another near a plant in operation
(Hamaoka) and one without plants nearby (Kyoto). Among
the findings, the preference to expand nuclear power was 28
percent, while that to decrease it was 11 percent. In
addition, the community acceptance may shift from 28 to 65
percent in a special case of constrained acceptance. People
living near the planning and the consumption sites had the
highest acceptance rates and the least polarised view towards
NPPs expansion. Among the analysed factors of influence,
“Inclusion in the decision process” had a significant
correlation with both cases of acceptance (b=0.22). Some
measures to improve community acceptance before plans for
NPPs expansion are included as recommendations.

Determination of the radioactive isotopes concentrations in the petroleum waste of sludge and sand is an
essential issue not only to refineries, industrial processing, waste disposal and transports but also, to human health and the
environment. As these radioactive isotopes are radiation risky, therefore they should be assessed and controlled. Moreover,
they might contain heavy and toxic elements which cause hazardous pollution. This paper will focus on the evaluation of
the concentrations of metals, heavy and toxic elements in sludge samples from different petroleum companies’ sites located
in the eastern Egyptian desert. Five sludge oil samples were elementally analyzed by Neutron Activation Analysis (NAA)
technique. The samples were irradiate using the irradiation box inside the Egyptian second research reactor (ETRR-2)
(rabbit irradiation system) for 4 hours and then counted after 14 days using HPGe detector. 18 isotopes named (Ca, Sc, Cr,
Fe, Co, Zn, Br, Rb, Sr, Ag, Sb, Cs, Ba, Eu, Yb, Lu, Hf, and Ta) were detected with different concentrations in the samples
under investigation. The isotopes of Ca, Fe, Sr, and Ba had high concentrations compared with other isotopes in the
samples. The toxic element of barium with high concentration and other trace elements with low concentrations were
detected in the samples. High concentration of Fe trace elements above the standard level was detected in all samples. The
outcomes of the study imply that more monitoring is needed for the petroleum waste in these locations to minimize the
environmental pollution and to minimize the radiation risk for the workers.

The treatment of drug-resistant cancer is a clinical challenge, hence screening for novel anticancer drugs is critically important. In the present study we investigated the anti-tumor potential of three plant-derived flavone compounds 3-hydroxy flavone (3-HF), 6-hydroxy flavone (6-HF) and 7-hydroxy flavone (7-HF) either alone or combined with silica nanoparticles (3-HF+NP, 6-HF+NP and 7-HF+NP) on the human breast carcinoma cell lines MDA-MB-231 and MCF-7, as well as on non-tumorigenic normal breast epithelial cells (MCF-10). The IC50 values of these flavone compounds loaded with NP (flavones+NP) in these cell lines were determined to be 1.5µg/ml without affecting the viability of normal MCF-10 cells. Additionally, we found that combination of flavones with NP significantly induced apoptosis in MCF-7 and MDA-MB-231 cancer cells using annexin-V/PI double staining followed by flow cytometry analysis. Furthermore, flavones+NP increased the expression of cytochrome C and caspase 9 mediating growth arrest of these cancer cells. Most importantly, combination of flavones with NP significantly abolished the expression of ATF-3, which in turn is responsible for the proliferation and invasion of bone metastatic breast cancer cells. Our data revealed the potential therapeutic effects of these flavones in fighting breast cancer cells and provided the first insight concerning the underlying molecular mechanisms.
