Conventionally, chromium is deposited from hexavalent chromium baths containing extremely toxic compounds of Cr (VI). Due to serious health and environmental concerns of Cr (VI), trivalent chromium bath is proposed as a counter approach towards greener and safer chromium plating. In the present work, chromium coatings…
In this paper, taken the deep-sea transformer as the research goal and based on the numerical model method, the finite two-dimensional numerical model of deep-sea transformer is established by ANSYS and the leakage magnetic field and winding loss of the transformer are calculated. Then based on the two-dimensional num…
New approaches that build on the traditional methods for materials synthesis and characterization are discussed with a specific focus on realizing novel intermetallics. Indeed, advances in the computational modeling of solids using density functional theory in combination with structure prediction algorithms have led…
Purpose In this study, it is aimed to synthesize ultraviolet (UV)-curable water-borne polyurethane acrylate (WPUA) binders using different types of polyols (poly (propylene glycol), PPG1000 and PPG2000 and poly (ethylene glycol), PEG1000 and PEG2000) at different molecular weights, DMPA (2,2-bis(hydroxymethyl) propion…
Several full-dimensional potential energy surfaces (PESs) are reported for vibrating CO adsorbates at two coverages on a rigid NaCl(100) surface based on first principles calculations. These PESs reveal a rather flat energy landscape for physisorption of vibrationless CO on NaCl(100), evidenced by various C-down adsor…
Seismic isolation is one of the most effective options for passive protection of structures. In this paper, the effectiveness of Shape Memory Alloy (SMA) based Natural Rubber Bearing (NRB) with Double Cross (DC) SMA wire configuration is presented. Based on the aspect ratio (R) two types of DC-SMA NRBs are considered:…
Using the method of time-resolved magnetic field effect in radiation-induced fluorescence, primary radical cations (RCs) in irradiated poly(isobutylene) (PIB) have been detected for the first time. A comparison of experimental results with the data of quantum chemical calculations suggests that the initial geometry of…
Degradation of Congo red dye was studied using synthesized nano TiO 2 and carbon under visible light. The nano materials were synthesized by sol-gel and co-precipitation doped TiO 2 methods. The synthesized nanoparticles were characterized by XRD and SEM. The band gap energy was found to be 2.88 eV. All the experiment…
Synthetic polymers that are brittle at or below room temperature need additives to expand their toughness over a broad temperature range. As graft rubber technology developed, it became apparent that, in addition to grafted particles, a fraction of much larger rubber particles was needed. R. Czerwinski patented a meth…
We experimentally demonstrate the use of orbital angular momentum (OAM) modes as a degree of freedom to facilitate the networking functions of carrying header information and orthogonal channel coding. First, for carrying channel header information, we transmit a 10 Gb/s on–off keying (OOK) data channel as a Gaussian…
Hydrogels are three dimensional cross linked polymer networks, linked through chemical or physical interactions, and has the capacity to absorb large amounts of water. Hydrogels that are biocompatible have medicinal applications. The water absorbency of gels may depend on pH, temperature, ionic strength. Acrylamide (A…
High-energy incident particles from both pulsed and continuous radiation sources can induce significant damage to the structure of a material by creating vacancy-interstitial pairs and other more complex defects, and this leads typically to localized melting. In this work, we present evidence via molecular dynamics si…
Response represents the management of diversion suspicions and, therefore, potentially materialised diversion risk. Investigations are technical activities that involve the management of a range of risks and should not be undertaken lightly. A key benefit is that detection informs good risk assessment and control plan…
Reduction of threading dislocation density (TDD) in epitaxial germanium (Ge) on silicon (Si) has been one of the most important challenges for the realization of monolithically integrated photonics circuits. The present paper describes methods of theoretical calculation and experimental verification of a novel model f…
Silver nanoparticles (Ag NPs)are in great trend these days because of their miraculous and unique properties which is quite helpful in the medical field. Various methods over the years have been devised to synthesize silver nanoparticles. In this research one such green method is presented i.e. synthesis of Ag NPs usi…
La abrasión es una importante acción mecánica que afecta a los elementos de concreto que soportan tránsito intenso o conducen líquidos. Los factores que más influyen en la resistencia a la abrasión de este material son la dosificación de la mezcla, la resistencia de los agregados, el acabado y el curado. En muchas par…
Cerium(IV) oxide (CeO₂) powder is shock compressed using the Precision High Energy-density Liner Implosion eXperiment (PHELIX) platform. Experimental results are compared against several modeling approaches. Compaction behavior is best captured with a P-∝ model, which calculates CeO₂ powder bulk densities within 80-99…
Water is a precious resource but due to the increased population and industrialization, the amount of water used for various purposes like drinking, sanitization and industrial use has also increased. The industrial wastewater is many a times coloured due to the type of impurities present in it. The wastewater from th…
Alizarin Red is a water soluble anthraquinone dye used extensively in the textile industry as a staining agent and is considered to be one of the most recalcitrant and durable pollutants. Fenton reaction can be used to destroy a wide variety of organic compounds: a ferrous ion reacts with hydrogen peroxide (H2O2) to f…
Graphene is one of the most suitable nanomaterials to enhance the mechanical properties of the base material. In the present work graphene has been considered as a filler material to enhance the mechanical properties of different base materials namely; gold (Au), aluminum (Al), copper (Cu), iron (Fe) and magnesium (Mg…
