The growth of solar energy generating systems starts in the 1970s with first applications of solar cell and photovoltaic (PV) technologies. The rapid decrease of manufacturing costs thanks to a massive growth in mass production of photovoltaic modules and subsequent help from government incentives that have facilitated the deployment of this technology in every sector.1 The introduction of renewable sources changed the background of the energy sector. The energy generated by biomass, geothermal, wind, photovoltaic (PV) and concentrated solar thermal (CST) plants has introduced indeed new challenges for energy operators who have had to address energy market needs differently. The United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto protocol have led to agreement between nations on climate change and the need to reduce greenhouse gas emissions. The mitigation of CO2 and NOx pushed energy operators to rely on variety of ‘‘green” energy production technologies. Thus, the development and installation of photovoltaics and wind plants widely increased during past three decades generating a learning curve for both manufacturers and energy market operators. The downside of both renewable technologies is the intermittence of electrical generation as it is function of weather conditions. A full conversion to solar and wind energy is not then a feasible solution to satisfy a flexible and continuous energy market demand, hence these technologies are usually employed to respond to energy peak requests, mostly.

The phase shift’s influence of two strong-pulsed laser waves on effective interaction of electrons was studied. Considerable amplification of electrons repulsion in the certain range of phase shifts and waves intensities is shown. That leads to electrons scatter on greater distances than without an external field. The value of the distance can be greater on 2-3 orders of magnitude. Also, considerable influence of the phase shift of pulses of waves on the possibility of effective attraction of electrons is shown.

Gonorrhea is the second most prevalent sexually transmitted infection globally. Neisseria gonorrhoeae, the etiological agent of gonorrhea, is evolving into a superbug and may become untreatable due to its resistance to almost all the antibiotics available. There is a critical need for the development of alternative therapeutics. This pilot study aimed to investigate the potential of an innovative non-antibiotic approach, antimicrobial blue light (aBL), as an alternative therapeutic for gonococcal infections. We studied one ATCC strain (ATCC 700825) and one multidrug-resistant clinical strain of N. gonorrhoeae. The results demonstrated that both the strains are highly susceptible to aBL at 405nm. In planktonic suspensions, an exposure of 45 J/cm2 aBL reduced the survival fraction of colony-forming units (CFU) by 7.16-log10 for ATCC 700825 and 2.48-log10 for the clinical strain. When the aBL exposure was further increased to 54 J/cm2, a complete eradication of CFU (over 8-log10 CFU reduction) was achieved for ATCC 700825 and a reduction of 5.43-log10 CFU was obtained for the clinical strain. In addition, we observed that singlet oxygen plays a vital role in the antimicrobial effect of aBL on N. gonorrhoeae. In conclusion, the results of this pilot study suggest that aBL is a promising approach to combat gonococcal infections. Further studies are warranted in the analysis of the endogenous photosensitizers in N. gonorrhoeae cells, evaluation of the aBL efficacy against gonococcal infections in animal models, and investigation of the mechanism of action of aBL.
