Faster Than Light and EM-Wave Anomalous Propagation

Huang Zhixun

Strategic Study of CAE 2000, Volume 2, Issue 10,   Pages 80-92

Abstract:

In this paper, the historic background of the study on faster than light (FTL) and the possibility of working within the frame work of special relativity are discussed. The previous experimental studies with single photon, laser pulse and microwaves have revealed superluminal behavior in the quantum tunneling process. That phenomenon exists only in the case of special physical condition. The analogy between classical Telegraphist equation and Klein-gordon equation can be used to study particle tunneling and superluminal behavior. A discussion on the FTL experiment by Dr. L. Wang recently is included. Remarks on the future of FTL research is given in this article.

Flow cytometric assessment of the effects of chlorine, chloramine, and UV on bacteria by using nucleic acid stains and 5-cyano-2,3-ditolyltetrazolium chloride

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 6, doi: 10.1007/s11783-016-0884-4

Abstract: Flow cytometry based on nucleic acid stains and CTC was established and optimized. Membrane of is more resistant to chlorine/chloramine than . The metabolic activity of bacteria persisted after the cytomembranewas damaged. showed more resistance to UV irradiation than by FCM. MP-UV was a stronger inhibitor of metabolic activity than LP-UV. Flow cytometry (FCM) has been widely used in multi-parametric assessment of cells in various research fields, especially in environmental sciences. This study detected the metabolic activity of and by using an FCM method based on 5-cyano-2,3-ditolyltetrazolium chloride (CTC); the accuracy of this method was enhanced by adding SYTO 9 and 10% R2A broth. The disinfection effects of chlorine, chloramine, and UV were subsequently evaluated by FCM methods. Chlorine demonstrated stronger and faster destructive effects on cytomembrane than chloramine, and nucleic acids decomposed afterwards. The metabolic activity of the bacteria persisted after the cytomembranewas damaged as detected using CTC. Low-pressure (LP) UV or medium-pressure (MP) UV treatments exerted no significant effects on membrane permeability. The metabolic activity of the bacteria decreased with increasing UV dosage, and MP-UV was a stronger inhibitor of metabolic activity than LP-UV. Furthermore, the membrane of Gram-positive was more resistant to chlorine/chloramine than that of Gram-negative . In addition, showed higher resistance to UV irradiation than .

VITHM1 mediated green synthesis of silver nanoparticles: Mechanism and biological applications

Mani Abirami, Krishnan Kannabiran

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 4,   Pages 542-551 doi: 10.1007/s11705-016-1599-6

Abstract: We present the microbial green synthesis of silver nanoparticles (NPs) by VITHM1 strain (MTCC No. 12465). The secondary metabolites in the cell free supernatant of this bacterium when incubated with 1 mmol/L AgNO , mediated the biological synthesis of AgNPs. The synthesized AgNPs were characterized by UV-visible spectrum, X-ray diffraction (XRD), atomic force microscope, scanning electron microscopy equipped with energy dispersive spectroscopy, transmission electron microscopy, FT-IR spectroscopy, dynamic light scattering and zeta potential. They were highly stable and, spherical in shape with the average size of 30?50 nm. The secondary metabolites involved in the formation of AgNPs were identified gas chromatography-mass spectrography. The 3D structure of the unit cell of the synthesized AgNPs was determined using XRD data base. The synthesized AgNPs exhibited significant antibacterial activity against tested bacterial pathogens, and did not show haemolysis on human red blood cells. This green synthesis could provide a new platform to explore and use AgNPs as antibacterial therapeutic agents.

Enhanced disinfection of <em>Escherichia coliem> and bacteriophage

Guiying RAO, Kristen S. BRASTAD, Qianyi ZHANG, Rebecca ROBINSON, Zhen HE, Ying LI

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 4, doi: 10.1007/s11783-016-0854-x

Abstract: A novel photocatalytic Ag-Cu-TiO nanowire membrane was fabricated. Bacteria and virus disinfection was improved by co-depositing Ag and Cu onto membrane. Synergetic photocatalytic effects and free metal ions of Ag and Cu contribute to disinfection. 7.68 log removal of and 4.02 log removal of bacteriophage MS2 were achieved. Titanium dioxide (TiO ) is a widely used photocatalyst that has been demonstrated for microorganism disinfection in drinking water. In this study, a new material with a novel structure, silver and copper loaded TiO nanowire membrane (Cu-Ag-TiO ) was prepared and evaluated for its efficiency to inactivate and bacteriophage MS2. Enhanced photo-activated bactericidal and virucidal activities were obtained by the Cu-Ag-TiO membrane than by the TiO , Ag-TiO and Cu-TiO membranes under both dark and UV light illumination. The better performance was attributed to the synergies of enhanced membrane photoactivity by loading silver and copper on the membrane and the synergistic effect between the free silver and copper ions in water. At the end of a 30 min test of dead-end filtration under 254 nm UV irradiation, the Cu-Ag-TiO membrane was able to obtain an removal of 7.68 log and bacteriophage MS2 removal of 4.02 log, which have met the US EPA standard. The free metal ions coming off the membrane have concentrations of less than 10 ppb in the water effluent, far below the US EPA maximum contaminant level for silver and copper ions in drinking water. Therefore, the photo-activated disinfection by the Cu-Ag-TiO membrane is a viable technique for meeting drinking water treatment standards of microbiological water purifiers.
