Presently, sustainable energy as well efficient and economical conversion storage technologies has become important work in light of the rising environmental issues dependence on portable uninterrupted power sources. Increasingly more researchers are focusing harvesting converting solar energy, mechanical vibration, waste heat, wind to electricity. Electrical play a significant role demand for green energy. Rechargeable batteries or secondary batteries, such Li-ion Na-ion Mg-ion reversibly...
Expanding hydrated vanadate with transition metal cations collectively promotes and catalyzes fast more Zn-ion intercalation in aqueous batteries.
Layered double hydroxides (LDHs) have attracted tremendous interest for applications in energy harvest and storage. However, the aggregation of nanosheets compromises accessible active sites limits their electrochemical performance, especially at high rates. The present study reports synthesis highly dispersed NiFe-LDH anchored on reduced graphene oxide (NiFe-LDH/rGO) composites chemically bonded via a facile one-step hydrothermal method. Defect-riched rGO provides abundant heterogeneous...
Adjusting synthesis pH of EDTA chelate assisted precipitation FeHCF affects particle size, vacancies, water content, and redox activity.
In situ X-ray absorption spectroscopy and optical imaging confirm the role of selenium additives for enhancing power performance, increasing utilization, suppressing undesirable side reactions in Li–sulphur batteries.
To reach energy density demands greater than 3 mA h cm-2 for practical applications, the electrode structure of lithium-sulfur batteries must undergo an architectural redesign. Freestanding carbon nanofoam papers derived from resorcinol-formaldehyde aerogels provide a three-dimensional conductive mesoporous network while facilitating electrolyte transport. Vapor-phase sulfur infiltration fully penetrates >100 μm thick electrodes and conformally coats aerogel surface providing areal...
Pb-jarosite, Pb0.5Fe3(SO4)2(OH)6, was investigated for the first time as an intercalation cathode lithium-ion batteries. Despite having a lower theoretical specific capacity than its Na-jarosite analogue, NaFe3(SO4)2(OH)6, bulk Pb-jarosite displayed higher capacity, especially at current rates. The greater lithium storage is attributed to more kinetically facile diffusion of in evidenced by potentiostatic intermittent titration technique data, indicating average coefficient over 10 times...
In this research, the application of vacuum‐evaporated nanostructured ZnO thin films as a photoanode and its use in quantum dot‐sensitized solar cells (QDSSCs) is reported. Quantum dots (CdS/CdSe) are deposited through successive ionic layer adsorption reaction (SILAR) technique. Thirty nanometers average size nanoparticles synthesized from solution used source, resultant thickness starts 200 nm to 3 microns. Average crystal phase identification done by XRD. Scanning electron microscopy...
Freshwater, a resource critical to social and economic stability, can become temporarily inaccessible after natural disasters such as earthquakes hurricanes. Transport of water remote areas during emergencies is expensive potentially dangerous. Production fresh from local brackish saline resources requires compact, mobile energy-efficient devices. Reverse-osmosis (RO) uses high-pressure pumps that make down-sizing scales challenging, while an alternative RO, capacitive deionization (CDI)...
Sulfur-based batteries have emerged as a leading contender for next-generation energy storage owing to their high redox capacity and the global availability of elemental sulfur. Yet electronically insulating nature sulfur limits applicability this battery chemistry. Redox kinetics are enhanced by coating onto conductive, porous carbon scaffold 1 atomically mixing with selenium. 2 Electrochemical discharge S/Se blends exhibit additional voltage plateaus compared pure S cathode in-situ optical...
Lithium–sulfur (Li–S) batteries promise high energy density and sustainability advantages by using earth-abundant sulfur as a key component, yet practical performance is limited the complexity of sulfur-based redox reactions....
Potable water is an essential supply for humanitarian missions worldwide, yet delivering pre-purified to remote locations challenging, dangerous, and expensive. Therefore, it desirable develop deploy on-site portable desalination/water-purification equipment that draws on local sources. Present reverse-osmosis systems effectively desalinate seawater, but are energy time-intensive, require regular maintenance due membrane fouling, suffer from poor scalability. Capacitive deionization (CDI)...
Electrochemical approaches to water desalination show promise for processing brackish water, but continued progress relies on developing scalable electrode architectures with competitive capacity and uptake dynamics ion capture. Binder-free, device-ready carbon nanofoam papers (CNFPs) are one such candidate, where intermingled nanoscale networks of conductive pores balance the transport electrons ions throughout electrified interior. Microwave-assisted electroless deposition conformal...
