Effect of Starting Powder Particle Size on the Thermoelectric Properties of Hot-Pressed BiSbTe Alloys.

P-type BiSbTe polycrystalline pellets were fabricated using different methods: melting and mechanical alloying, followed by hot-press sintering. The effect of starting powder particle size on the thermoelectric properties was investigated in samples prepared using powders of different particle sizes (with micro- and/or nano-scale dimensions). A peak (350 K) of ~1.

3D Composite U(VI) Adsorbents Based on Alginate Hydrogels and Oxidized Biochar Obtained from .

3D naturally derived composites consisting of calcium alginate hydrogels (CA) and oxidized biochar obtained from (ox-LC) were synthesized and further evaluated as adsorbents for the removal of U(VI) from aqueous media. Batch-type experiments were conducted to investigate the effect of various physicochemical parameters on the adsorption performance of materials. The maximum adsorption capacity (q) was 1.

Evidence of Biorealistic Synaptic Behavior in Diffusive Li-based Two-terminal Resistive Switching Devices.

Following the recent advances in artificial synaptic devices and the renewed interest regarding artificial intelligence and neuromorphic computing, a new two-terminal resistive switching device, based on mobile Li ions is hereby explored. Emulation of neural functionalities in a biorealistic manner has been recently implemented through the use of synaptic devices with diffusive dynamics. Mimicking of the spontaneous synaptic weight relaxation of neuron cells, which is regulated by the concentration kinetics of positively charged ions like Ca, is facilitated through the conductance relaxation of such diffusive devices.

Impact of Job Satisfaction on Greek Nurses' Health-Related Quality of Life.

Background: Employee job satisfaction and its relationship with health and quality of life has been an issue of major concern over the past decades. Nurses experience difficult working conditions that affect their job satisfaction, health, and quality of life.

Methods: A cross-sectional study was undertaken in three general hospitals and their respective health centers.

Occurrence and variability of iodinated trihalomethanes concentrations within two drinking-water distribution networks.

Non-iodo-containing trihalomethanes (TTHM) are frequently detected in chlorinated tap water and currently regulated against their carcinogenic potential. Iodinated THM (ITHM) may also form in disinfected with chlorine waters that are high in iodine content, but little is known about their magnitude and variability within the drinking-water pipe distribution network of urban areas. The main objective of this study was to determine the magnitude and variability of ITHM and TTHM levels and their corresponding daily intake estimates within the drinking water distribution systems of Limassol and Nicosia cities of Cyprus, using tap samples collected from individual households (n=37).

Arsonoliposomes for the potential treatment of medulloblastoma.

Purpose: To investigate the arsonoliposome effect on medulloblastoma cells (VC312Rs) related to uptake, endocytotic mechanism and cell viability.

Methods: VC312R viability in presence of either arsonoliposomes or stealth liposomes was studied using MTT assay for 1-4 days. Fibroblasts (3T3) were used as control.

In vivo distribution of arsenic after i.p. injection of arsonoliposomes in balb-c mice.

We recently showed that arsonoliposomes (novel arsenic containg liposomes) demonstrate differential toxicity towards various types of cancer and normal cells, in cell culture studies, as well as anti-parasitic activity. In this study, the in-vivo distribution of the active moiety of these vesicles, As, is evaluated. Sonicated arsonoliposomes were prepared using the arsonolipid with palmitic acid acyl chain (C16) mixed with egg-phosphatidyl choline (PC) and cholesterol (Chol) [C16/PC/Chol at 8:12:10 mol/mol/mol].
