Multistage Model via Integrated Wind Thermal Energy Storage

Prof. H. Khaloiea et al., and his collaborative research team from various countries ( Shahid Bahonar University of Kerman, University of Bonab, Iran, University of Vaasa, Finland, Aalborg University, Denmark, University of Salerno, Italy, Faculty of Engineering of the University of Porto, Portugal) have reported a three-stage stochastic multi-objective offering framework or model-based upon a mixed-integer programming formulation for spinning reserve markets via Wind Thermal Energy Storage (WTES) generation were proposed. The utilization of renewable energy resources would have become one of the most essential requirements in our human life. Renewable energy resources like wind, or other integrated resources, were widely considered in various power systems, in particularly for the self-schedule offering of the strategic problems. Renewable energy resources were further divided into five general groups viz ., solar power, wind power, biomass, hydropower, and geothermal process [ 1

Perspectives of Tropical Cyclone Intensification

CYCLONE: “ A natural system of winds rotating inwards to an area of low barometric pressure, with the clockwise (southern hemisphere) or an anticlockwise (northern hemisphere) or with a circulation, and depression.” Tropical Cyclones (TC) are detected with the probability of their location, track, speed, and impacted link to anthropogenic climate change and their related analysis can be illustrated with observed scientific data, previous prediction, and satellite support over the global nature. TC motion is a central issue for the prediction and mitigation efforts, as it affects the location of storm-related damages. When TCs move slowly, the accumulated damage by TCs can be intensifying with a responsible one for a specific location. Global researcher's care in the new technical development of TC-permitting global and suitable regional climate simulations gives an opportunity for the research study to TC activities under altering climate conditions. The dynamical models (in sim

Gold nanocages: Photothermal related applications

Gold Nanocages  (AuNCs) are made up with a ultra-thin and porous walls of Au or Au-based alloys. It is the class of hollow, porous gold nanoparticles ranging in the size from 10 to over 150 nm. Generally, AuNCs are created by reacting silver nanoparticles with chloroauric acid (HAuCl 4 ) in boiling water. When AuNCs are irradiated with light, it exhibit a high efficiency for light-to-heat conversion and a large absorption cross section, making them effective photothermal transducers. Tuned AuNCs significantly absorb visible and near-infrared regions to optimize their interaction with the light at different wavelengths. AuNCs exhibits better photo-stability compared to the conventional organic dyes. These perspectives are of AuNCs synthesis and their use in applications involving photothermal conversion. Figure 1. Structure of NanoRod, NanoShell, NanoCage and AuNCs.  Recently, Qiu et al ., have reviewed the synthetic methods of AuNCs and their photothermal related applications, was rep

Minimal Cytotoxicity of Water-Soluble SiQDs with Blood Plasma Proteins Interaction

Prof. C. Shanmugavel et al., and his research collaboration team (from various universities at Japan) have been investigated on the interaction of blood plasma proteins and water-soluble silicon quantum dots (SiQDs) for the minimal cytotoxicity. This research investigation was reported in nanomaterials of MDPI publication journal and published on  13 th  November 2020. In this research article, they have reported on the conformational changes of blood plasma proteins during the interaction with near-infrared light-emitting nanoparticles, which comprised with assembled Pluronic-F127 coated semiconductor (silicon) QDs terminated with decane monolayers.   The semiconductor QDs have chosen as an alternative, owing to its high quantum yield and low photo bleaching characters by various researchers and scientists. Other previous research studies have also showed that the QDs has exhibited a molecular interaction with various proteins, which consists of toxic heavy metal ions (like mercury s

Multiple Perspective of Two Dimensional Materials

Ethan C. Ahn, from (The University of Texas at San Antonio, USA) deliberately discussed about the Two dimensional (2D) materials at the developing stages of electronic and magnetic properties with morphological materials as spintronic devices. 2D materials have gained more attentive for the utilization of inorganic semiconductors applications in this decades. A worldwide space is been occupied with 2D materials with their unique physical perspectives [ 1 ]. Scientists and technologists were interested to preface and details about the emerging society of 2D nanomaterials and spintronic devices. Highlights of 2D materials and their advantages in spin logic switches, spin valves, and spin transistors were specifically examined. They have also introduce the spin-orbit and spin-valley coupled properties of 2D materials to explore their potential to address the crucial issues of contemporary electronics. Finally, they have highlighted the major challenges in integrating 2D materials into spi

Pottery Shard CNTs Discovery in Sixth Century: Keeladi, Tamilnadu, India

Prof. Manivannan et al., and his research collaboration team have been investigated the discovery of carbon nanotubes in sixth century BC potteries that have obtained from Keeladi, Tamilandu, India. This investigation has reported in Nature publication journal of “Scientific Reports” on 13 th November 2020 [ 1 ]. This is one of the most interesting reports and scientific research from Keeladi excavation located in the southern part of India. Keeladi Excavation: The excavation was first started in Pallisanthai Thidal which is in the north of Manalur, about a kilometer east of the town of Keeladi in Sivagangai district, Tamilnadu, India. Number of various archaeological residues were found in this excavation, when plowing the land around the site. The first survey was conducted in 2013 in the vicinity of the Vaigai river, 293 sites were identified during the study including Keeladi, and all this sites have an archaeological residues [ 2 ]. A part of excavation, researchers found carbon

“Integrating Renewable Energy System: Repowering Project”

Delightful of massive activities and goals to develop energy management of the following organization/agency: Global Wind Energy Council (GWEC), United Nations Framework Convention on Climate Change (UNFCCC), International Energy Agency (IEA), International Renewable Energy Agency (IRENA), and Renewables Global Status Report (REN21). The key to today’s need of sustainable energy challenges to ensure the wind power technology which they announced specifically was established with their economic benefits of low cost schemes. Nowadays, in the wind energy sector, assessing the technical and economical calculations for the repowering of wind farms are increased at various countries such as European, India, China, and United States. The roles of GWEC were developed over 1,500 companies, institutions, and organizations worldwide (80 countries). Their team assisted to implement the wind energy productions with the following ideas of manufacturer, developer, spare part suppliers, research in
