Abstract:

Abstract One of the emerging problems in medicine and dentistry today is how to replace and regenerate damaged tissue. Currently used implants are inert and need to be replaced after a certain period. Therefore, the aim is to develop a bioactive multicomponent material that can promote tissue regeneration. Hydrogels are the focus of research in this field because of their similarity to the natural extracellular matrix and their good biocompatibility. Nevertheless, hydrogels often have insufficient mechanical properties for handling and implantation. Therefore, methods of hydrogel reinforcement

Abstract The solution-gate graphene field effect transistor (Sg-GFET), as a popular sensing platform, its applications are still hindered by the deficiency in all-solid-state, due to the dependence on liquid-state gate-dielectric. Inspired by DNA hydrogel which can provide microporous architecture to accommodate the fluidic analyte, moreover, its combination with graphene is believed to foster electron transport in the field of electrochemistry. We are interested to take advantage of DNA hydrogel's solid-state and capability for holding solution, and investigate whether it can replace the trad

Abstract:

The dependence of the band structure of lanthanum hybrides on hydrogen concentration is investigated by considering an approximate model Hamiltonian that takes into account the hybridization of the d and hydrogen-derived s bands. A Green's function technique is used to obtain the hybrid bands in the Hartree–Fock approximation. The model is used to discuss the role of H concentration and the s–d interaction on the observed metal–semiconductor phase transition in LaHx.

<em>This work looks at optimizing the performance of proton exchange membrane and solar hydrogen fuel cell in a hybrid system for efficient power generation using artificial intelligence. This kind of decentralized system is frequently located in remote and inaccessible areas with no access to electric  grid. How to control and handle power is one key issue confronting hybrid renewable power generation system due to their unstable nature. Fuel cell is integrated with the photovoltaic as a means of support since the PV is not dependable during bad weather or at night. The data used for the

Abstract:

In a technically advanced world where demand is increasing very fast especially large number of non-linear loads and electric vehicles has led to energy crisis and pollution of grid power. Depleting conventional energy sources and environmental concerns has led to integration of large number of distributed energy resources (DERs) at distributional level to resolve problem of energy crisis and reduce emissions. With grid connected to different types of DERs, it is very challenging to manage the power flow, resolve energy crisis and maintain good power quality. Improper energy management may lea

Intra-city travel is a significant part of urban life and a fully functional intra-city transit system will help in reducing the number of private vehicles on the road, thus reducing pollution and traffic congestions. A robust urban transit system helps in the physical expansion of city limits, making education, job, and medical facilities accessible to people living in city fringe areas. This will help in depopulating the Central Business District areas and optimization of real estate cost. Heavy Rail Based Metro Transit system has improved living conditions in Metropolitan cities.

Abstract:

Nano TiO2, one of the most effective photocatalysts, has extensive usein fields such as air purification, sweage treatment, water spitting, reduction of CO2, and solar cells. Nowadays, the most promising method to recycle nano TiO2during the photocatalysis is to immobilize TiO2onto matrix, such as polyvinyl alcohol (PVA). However, due to the slow water permeability of PVA after cross-linking, the pollutants could not contact with nano TiO2photocatalyst in time. To overcome this problem, we dispersed calcium carbonate particles into a PVA-TiO2 mixture and then filmed the glass. PVA-TiO2-CaCO3 f

Abstract:

The hybrid hydrogen storage method consists of the combination of both solid-state metal hydrides and gas hydrogen storage. This method is regarded as a promising trade-off solution between the already developed high-pressure storage reservoir, utilized in the automobile industry, and solid-state storage through the formation of metal hydrides. Therefore, it is possible to lower the hydrogen pressure and to increase the hydrogen volumetric density.

AbstractControlling the adverse effects of global warming on human communities requires reducing carbon dioxide emissions and developing clean energy resources. Fossil fuel overuse damages the environment and raises sustainability concerns. As a resource‐rich element, cobalt oxide hybrids have attracted considerable attention as low‐priced and eco‐friendly electrocatalysts. Alkaline solutions disperse Co3O4 easily despite its highly stable nature, which arises from the reverse spinel structures of Co.

Organic-inorganic hybrid perovskites have gained great attention as promising photocatalysts for hydrogen generation. However, due to their poor stability in water, the use of aqueous hydrohalic acid solutions is specifically required for an efficient hydrogen evolution. Herein, three novel photoactive lead-free hybrid perovskites based on bismuth and triazolium cations (denoted as IEF-15, IEF-16, and IEF-17) were synthesized and fully characterized (structural, compositional, optical, etc.). Further, these solids were proposed as photocatalysts for the challenging gas phase overall water spli

Abstract:

Solid oxide fuel cells (SOFC) have developed to a mature technology, able to achieve electrical efficiencies beyond 60%. This makes them particularly suitable for off-grid applications, where SOFCs can supply both electricity and heat at high efficiency. Concerns related to lifetime, particularly when operated dynamically, and the high investment cost are however still the main obstacles toward a widespread adoption of this technology. In this paper, we propose a hybrid cogeneration system that attempts to overcome these limitations, in which the SOFC mainly provides the baseload of the system

It is estimated that the total cost of abnormal conditions to US process industries is around $20 billion dollars in annual losses. The hydrotreatment (HDT) of diesel fuel in petroleum refineries is a conversion process that leads to high profitable economical returns. However, this is a difficult process to control because it is operated continuously, with high hydrogen pressures and it is also subject to disturbances in feed properties and catalyst performance. So, the automatic detection of fault and diagnosis plays an important role in this context. In this work, a hybrid approach based on

Alternative electrocatalyst materials such as transition metal oxides and sulfides can undergo insertion reactions that change their properties.
