The effect of the partial substitution of x = 0.02 Fe for Cu in the stabilized (Bi, Pb):2223 phase has been investigated by magnetoresistivity measurements up to 0.7 T. The intra- and intergranular transitions as a function of magnetic field were analysed using versus T curves.

The partial substitution of Fe for Cu on the electrical and magnetic properties of (Bi1.6Pb0.4)(Sr1.8Ba0.2)Ca2(Cu1−xFex)3Oy (0 × 0.05) has been investigated by electrical resistance, magnetic a.c. and static susceptibilities measurements. The superconducting transition temperatureTc decreases with increasing Fe concentration and the samples are characterized by a linear temperature dependence of the electrical resistance above2Tc. The excess conductivity was analyzed. The inter- and intragrain critical ...

The intergranular properties of ( Y 1-x-y Zr x Ca y ) Ba 2 Cu 3 O 7-δ ceramics were studies by using temperature-dependent ac susceptibility measurements at zero dc magnetic field. The intergranular critical current density was determined from ac susceptibility data by varying the field amplitude H ac . From the imaginary part of the complex susceptibility, χ″(T), we have determined the temperature dependence of the critical current density by using the Bean's model. The ac field dependencies of the intergrain ...

Viral infections occupy an essential place in modern medicine, particularly a large group of diseases caused by the influenza viruses. They are rapidly transmitted and mutate quickly, which can lead to significant socio-economic consequences. Silver nanoparticles (AgNPs) are considered to be an effective antimicrobial agent. This study shows that they have strong antiviral properties against the influenza A virus infection. Their absence of cytotoxicity at inhibitory concentrations demonstrates that ...

ZnO nanocrystals doped with Nd, Gd, and Er were synthesized using a soft chemical process in ambient atmosphere. Pseudospherical and hexagonal nanocrystals (NC) of the wurtzite phase with a mean size of (7.4 ± 1.7) nm were obtained. The presence of rare earth (RE) dopants was confirmed by X-ray fluorescence (XRF) spectroscopy. The ZnO nanocrystals exhibited simultaneously narrow excitonic- and broad trap/surface-related photoluminescence (PL), both of which were affected by doping with RE atoms. Doping ...

Using first-principles electronic structure calculations performed within the B1-WC hybrid functional, we study the thickness and strain dependency of electronic and thermoelectric (TE) properties of transition-metal dichalcogenides (TMDs). We consider both 2H (MoS2, MoSe2, MoTe2, WS2, WSe2, WTe2) and 1T (SnS2, SnSe2, HfS2, HfSe2, HfTe2, ZrS2, ZrSe2) structures and identify those TMDs with a high TE potential (WSe2, MoTe2, and SnSe2). The thickness and strain significantly change the electronic properties ...

Proprioception, the sense of limb and body position, generates a map of the body that is essential for proper motor control, yet we know little about precisely how neurons in proprioceptive pathways are wired. Defining the anatomy of secondary neurons in the spinal cord that integrate and relay proprioceptive and potentially cutaneous information from the periphery to the cerebellum is fundamental to understanding how proprioceptive circuits function. Here, we define the unique anatomic trajectories ...

Nanostructured alloy powders of SmCo5 + 10 wt% Fe obtained using recycled material were studied for the first time. The SmCo5 precursor was obtained from commercial magnets recycled by hydrogen decrepitation. The results were compared with identically processed samples obtained using virgin SmCo5 raw material. The samples were synthesized by dry high-energy ball-milling and subsequent heat treatment. Robust soft/hard exchange coupling was observed—with large coercivity, which is essential for commercial ...

Prof. Pietro Omodeo (University of Siena, Italy), the world-renowned earthworm taxonomist and evolutionary biologist, was born in Cefalù, Sicily, Italy on the 27th September, 1919. He celebrates his 100th birthday in 2019 and members of the international community of earthworm taxonomists salute him with Petroscolex centenarius gen. et sp. nov., a new megadrile taxon discovered in 1991 by him but which has not been formally described until now. The many important contributions of Omodeo to oligochaetological ...

Abstract Androsta-1,4-dien-17β-ol-3-one, also known as boldenone, is an anabolic-androgenic steroid derived from testosterone. The crystal structures of boldenone base, boldenone acetate, boldenone propionate, boldenone cypionate and a boldenone acetate polymorph obtained by high throughput screening were investigated. Hirshfeld surfaces and fingerprint plots breakdown revealed that the molecular packing in the crystals are driven by dominant H⋯H intermolecular contacts, followed by O⋯H/H⋯O contacts ...

Detailed theoretical and experimental investigations on the electronic and magnetic properties of the Mn2Co1−xVxAl Heusler compounds are presented. The magnetization vs. temperature measurements on the Mn2Co1−xVxAl Heusler compounds show a decrease of the Curie temperature with V content, between 745 K (x = 0) and 671 K (x = 0.5). Ferrimagnetic near fully compensated behaviour with the saturation magnetization of 0.29 μB/f.u. has been obtained experimentally for Mn2Co0.5V0.5Al alloy, in slight disagreement ...

Transparent thin films of Al-doped ZnO (AZO), Ga-doped ZnO (GZO) and codoped Al + Ga ZnO (AGZO) were deposited on soda-lime glass by RF magnetron sputtering. The influence of aluminum and gallium concentrations in zinc oxide (ZnO) films on structural and optical properties of thin films were studied. XRD results shown that the obtained films were with a hexagonal wurtzite structure and preferentially oriented perpendicular to the substrate surface. Atomic force microscopy (AFM) evidenced that the type ...

Abstract Dendrobaena byblica (Rosa, 1893) is a Circum-Mediterranean species complex composed of at least 17 nominal taxa. Regarding the most important species characters (clitellum and tubercles) the worms belonging to the genus Fitzingeria Zicsi, 1978 seem to be very close to the D. byblica species group. Here we provide the first molecular phylogenetic analysis of the byblica species group and the Fitzingeria species, and show that the genus Fitzingeria is polyphyletic and groups together with the ...

Detailed theoretical and experimental investigations on the electronic and magnetic properties of the Heusler compounds Mn2-xCoxVAl with L21 structure are presented. The samples have been examined by X-ray diffraction, magnetization measurements and X-ray photoemission. The magnetic measurements show that the Curie temperatures decrease with Co content, ranging between 771 K (x = 0) and 289 K (x = 1), while the magnetization of the samples follows the Slater-Pauling rule. Additionally, electronic band ...

Sexuality education for children and adolescents plays a crucial part in their sexual and reproductive health and general well-being.

The structural, electronic and magnetic behavior of the as-cast and annealed Mn50Al46Ni4 and Mn54Al46 alloys was investigated. It was found that annealing at 470 °C promotes the formation of the τ phase in both alloys, however, all of the prepared samples were phase mixtures. The τ phase was found along with the κ phase (CsCl-type structure) only in the Mn50Al46Ni4 alloy. M(T) curves show two transitions at 437 K and 634 K corresponding to the ferromagnetic κ and τ phases, respectively. A maximum ...

Significance Ricin toxin (RT) is a CDC-designated select agent that can be dispersed as an aerosol. In mammals, aerosolized RT causes rapid and irreversible necrosis of the lung epithelium, multifocal hemorrhagic edema, and death within 24–36 h. A safe and effective recombinant subunit vaccine (RiVax) has been developed and formulated as a thermostable, lyophilized, adjuvant-containing “powder.” This formulation of RiVax elicited neutralizing antibodies against RT, which protected macaques from the ...
