We study the formation and gravitational collapse of supersonically induced gas objects (SIGOs) in early universe. run cosmological hydrodynamics simulations SIGOs, including relative streaming motions between baryons dark matter. Our also follow nonequilibrium chemistry molecular hydrogen cooling primordial clouds. A number SIGOs are formed with fast-streaming 2 times rms velocity fluctuations...

Water trapped between MoS2 and graphene assumes a form of ice composed two planar hexagonal layers with non-tetrahedral geometry. Additional water does not wet these but forms three-dimensional droplets. Here, we have investigated the temperature induced dewetting dynamics confined The crystals gradually decrease in size increasing substrate completely vanish at about 80 °C. Further heating to ...

Background and objectives: Tragopogon graminifolius DC. is widely used in Iranian traditional medicine as a gastro-protective and wound healer agent.  In the present study the hepatoprotective property of T. graminifolius DC. aqueous extract (TGAE) was investigated against carbon tetrachloride (CCl4) induced hepatocellular injury in mice. Me...

BACKGROUND/AIMS Endothelin-1 (ET-1) and the α1-adrenoceptor agonist phenylephrine (PE) activate cAMP response element binding protein (CREB), a transcription factor implicated in cardiac hypertrophy. The signaling pathway involved in CREB activation by these hypertrophic stimuli is poorly understood. We examined signaling pathways for ET-1- or PE-induced cardiac CREB activation. ME...

Perovskite solar cells (PSCs) have a great potential for space applications due to their high specific power, low cost and defect tolerance. PSCs used in will be subjected high-energy particle irradiation, especially proton resulting the decline of photovoltaic (PV) performance. However, research on irradiation effects is still its infancy stage. In this work, CH<sub>3</sub>NH<su...

fragrant species of the genus salvia have been attributed many medicinal properties, which include anticancer activity. in the present study, cytotoxic properties of total methanol extract of salvia chloroleuca rech. f. & aellen and its fractions were investigated on mcf-7, a breast carcinoma cell line. malignant and non-malignant cells were cultured in rpmi medium and incubated with different ...

The expanding range of optoelectronic applications lead-halide perovskites requires their production in diverse forms (single crystals, thin- and thick-films or even nanocrystals), motivating the development materials processing deposition routes that are specifically suited for these structurally soft, low-melting semiconductors. Pressure-assisted compact pellets gaining popularity, necessitat...

To address the unsatisfactory pressure sensitivity of luminescent manometers, Eu2+-activated supersensitive microspheres operating in visible range are developed. A series Eu2+-doped Sr8Si4O12Cl8 materials synthesized as microspheres, and their structural spectroscopic properties studied theoretically experimentally. Excited at 350 nm, samples emit a bright cyan luminescence ambient conditions ...
