A simple yet reproducible method to deposit high quality aluminium oxide (AlOx) film by spray coating is presented. Excellent thickness and refractive index uniformity is demonstrated. The AlOx film was found to be nearly stoichiometric with an oxygen to aluminium ratio of 1.7 from X-ray photoel...

The development of resistance in both stored grain and field insect pests to conventional insecticides, coupled with increased consumer awareness of the consequences of their residual toxicity in food crops and environmental contamination have led agro-chemical researchers to reappraise the use ...

Recently, various types of porous surfaces have been demonstrated for lubricant (e.g., oil) impregnated omniphobic surfaces. However, the retention of the lubricating liquid within the porous layer and the omniphobic durability still remain challenges. Here, the omniphobic durability of the oil-...

Mesoporous silica nanoparticles (MSNs) have been extensively investigated as drug delivery carriers due to their unique properties. Although MSNs synthesized using a very economic source of silica, sodium silicate, are promising carriers for drug delivery, information regarding their biocompatib...

Due to the shortage of fresh water, sea water has been considered as a promising alternative for mineral flotation. Sodium silicate (SS) was used to eliminate the negative influence due to the application of sea water for chalcopyrite flotation and the related mechanisms were studied. Flotation ...

We adopted sodium silicate to prepare composites of La(Fe, Si)13 hydrides in this work. A homogenous and continuous matrix of sodium silicate was formed at a relatively low solidification temperature. No counter diffusion between the matrix and the grains of La(Fe, Si)13 hydrides was observed. T...

The effect of polyhydroxy xanthan on the corresponding hydration process of cement and regulation mechanism was discussed, then sodium silicate as coagulant was added into the xanthan-retarded cement paste and its accelerating mechanism for the retarding effect of xanthan was investigated. The r...

With high theoretical energy density and the natural abundance of S, lithium-sulfur (Li–S) batteries are considered to be the promising next generation high-energy rechargeable energy storage devices. However, issues including electronical insulation of S, the lithium polysulfides (LiPSs) disso...

Hydrogen sulfide (H2S) is a gasotransmitter that regulates cellular homeostasis and impacts on multiple physiological and pathophysiological processes. However, it exerts many of its biological actions indirectly via the formation of H2S-derived sulfane sulfur species/polysulfides. Because of th...

SummaryThe shuttling of dissolved sodium polysulfides through conventional porous separators has been a challenging issue with the development of room temperature sodium-sulfur (RT Na-S) batteries. In this study, a NASICON-type Na+-ion solid-electrolyte membrane, Na3Zr2Si2PO12, is used as a poly...

A detailed study of kinetics of reaction between hydrogen sulfide and orthorhombic cyclooctasulfur at environmentally relevant conditions, which results in formation of inorganic polysulfides, was performed. Rates of reaction were measured as a function of pH, temperature and concentrations of S...

SummaryCysteine persulfide and cysteine polysulfides are cysteine derivatives having sulfane sulfur atoms bound to cysteine thiol. Accumulating evidence has suggested that cysteine persulfides/polysulfides are abundant in prokaryotes and eukaryotes and play important roles in diverse biological ...

Construction, components, and some properties of the bromine-polysulfide redox flow cell (Br/polyS RFC) are discussed in this section. For the bromine-polysulfide cell, various electrode materials, including activated carbon, carbon/graphite felt, nickel foam, and metal-coated graphite felt, are...

In-situ formation of pure olivine NaFePO4 from chemically synthesized LiFePO4 nanoparticles via an electrochemical ion-exchange route in sodium salt containing aqueous electrolyte is reported. Both in-situ electrochemical quartz crystal microbalance (EQCM) and in-situ X-ray diffraction (XRD) mea...

Though carbon-based porous materials have improved lithium-sulfur (Li-S) battery performance remarkably, the poor adsorption of polysulfides and their sluggish reaction kinetics limits them from practical application. On the other hand, the presence of lithium metal especially under the highly r...

The sodium-sulfur (Na-S) battery is a well-known large-scale electrochemical storage option. The disadvantages of this particular battery technology result from its high operation temperature. Room temperature sodium-sulfur (RT Na-S) batteries would overcome these issues, but have issues of thei...

There has been increasing interest in sodium-sulfur (Na-S) batteries as an option for low-cost grid-scale energy storage. However, traditional Na-S batteries operate at high temperatures, raising concerns about long-term maintenance costs and safety. On the other hand, room-temperature Na-S batt...

In this study, carbon molecular sieves (CMS) were produced from chestnut shell by chemical activation process followed by chemical vapor deposition (CVD) of methane. The influences of deposition temperature (800–900 °C), time (15–60 min) and flow rate of CH4 (100–300 mL/min) on pore developm...
