- Stable and compatible cathode materials are a key factor for realizing the low-temperature (LT, ≤600 °C) operation and practical implementations of solid oxide fuel cells (SOFCs). In this study, perovskite oxides SrFe1-xTixO3-δ (x < = 0.1), with various ratios of Ti doping, are prepared by a sol-gel method for cathode material for LT-SOFCs. The structure, morphology and thermo-gravimetric characteristics of the resultant SFT powders are investigated. It is found that the Ti is successfully doped into SrFeO3-δ to form a single phase cubic perovskite structure and crystal structure of SFT shows better stability than SrFeO3-δ. The dc electrical conductivity and electrochemical properties of SFT are measured and analysed by four-probe and electrochemical impedance spectra (EIS) measurements, respectively. The obtained SFT exhibits a very low polarization resistance (Rp),.01 Ωcm2 at 600◦C. The SFT powders using as cathode in fuel cell devices, exhibit maximum power density of 551 mW cm−2 with open circuit voltage (OCV) of 1.15 V at 600◦C. The good performance of the SFT cathode indicates a high rate of oxygen diffusion through the material at cathode. By enabling operation at low temperatures, SFT cathodes may result in a practical implementation of SOFCs.

- Viruses play an important role in cancerogenesis. It is estimated that approximately 20% of all cancers are linked to infectious agents. The viral genes modulate the physiological machinery of infected cells that lead to cell transformation and development of cancer. One of the important adoptive responses by the cancer cells is their metabolic change to cope up with continuous requirement of cell survival and proliferation. In this review we will focus on how DNA viruses alter the glucose metabolism of transformed cells. Tumor DNA viruses enhance “aerobic” glycolysis upon virus-induced cell transformation, supporting rapid cell proliferation and showing the Warburg effect. Moreover, viral proteins enhance glucose uptake and controls tumor microenvironment, promoting metastasizing of the tumor cells.

- Agricultural production has external costs embedded in different forms. These externalities have not yet been internalized in the market's prices. The study applied a basin-wide systematic approach to manage river salinity, which is one of the most vexatious of these externalities, and needs urgent remediation. The application of the approach is exemplarily demonstrated for the Murray Darling Basin (MDB) in Australia. An in-depth economic analysis indicates that in the upper areas, plant-based options are suitable and economically viable, while in middle and downstream parts of the MDB, more options are suitable such as irrigation management, subsurface drainage and effluent reuse, and salt interception systems and Sequential Biological Concentration (SBC). The SBC differs from most other options since it provides direct economic benefits to the operators and is profitable. We adopt Pigouvian recommendations as polluters pay principle to internalize externality. Charging salinity credits in terms of polluters pay principle (e.g. in this case of about A$53 t-1) would result in attractive economic returns even at higher level of salinity, thus offering sufficient incentives to invest in relevant salinity management strategy. We recommended that potential salinity mitigation technique should consider regional characteristics and that it should be focused on high impact salinity zones to increase the effectiveness of the effort.
