The characterization of as-deposited films by X-ray diffraction analysis revealed their amorphous nature. The optical constants of films were derived from transmittance spectra recorded in the 310–1100 nm wavelength range. All films were highly absorptive and showed a direct band to band transi

The subjunctive mood has been widely discussed from the perspective its selection in complements of volitional, directive and emotive-factive predicates (Picallo 1984, Raposo 1985, Ambar 1988, a.o.). Subjunctive questions and other type of subjunctive main clauses, on the other hand, have not been subject to much systematic research. Some works (Ambar 2016, Giannakidou 2016) suggest that, in main clauses, the selection of the subjunctive mood codifies the expression of the speaker’s evaluations. In line with this view, we discuss the syntactic expression of the Bulgarian dali-questions which d

Abstract Lead-composites products are usable materials for the personal protection of the patient from x-ray during radiation operations. Nevertheless, lead has high toxicity and environmental disadvantages. This research aims at the preparation of flexible, lead-free, and antibacterial composites for protection against x-ray radiation. At first, nanoparticles of molybdenum trioxide (MoO3), copper oxide (CuO), and tin (IV) oxide (SnO2) were synthesized with hydrothermal and sol-gel methods.

Single-layer MoS2-MoO3-x heterojunction nanosheets with visible-light-sensitive band gap energy and average lateral dimensions of ~70 nm were synthesized by using a two-step combined exfoliation method. The exfoliation was initiated from pristine MoS2, while some sulfur sites in expanded MoS2 sheets during exfoliating were substituted by ambient non-thermal oxygen, resulting in formation of α-MoO3-x crystalline domains. The morphological features, crystalline structure, phase formation, number of layers, and optical properties of the MoS2-MoO3-x nanosheets were determined by atomic force micro

For more than a century, cerebral cartography has been driven by investigations of structural and morphological properties of the brain across spatial scales and the temporal/functional phenomena that emerge from these underlying features. The next era of brain mapping will be driven by studies that consider both of these components of brain organization simultaneously—elucidating their interactions and dependencies. Using this guiding principle, we explored the origin of slowly fluctuating patterns of synchronization within the topological core of brain regions known as the rich club, implica
