Sodium metazirconate (Na2ZrO3) was synthesized, by solid-state reaction, and characterized. Water sorption experiments were performed using N2 and CO2 as carrier gases. In the absence of CO2, Na2ZrO3 showed considerably high water vapor sorption owing to two different processes, hydroxylation an...

Sodium niobate thin films doped with manganese (NN), and NN films modified with 5 or 10 mol % calcium zirconate (CZ) on platinized silicon substrates were prepared by chemical solution deposition. The 250-nm-thick films crystallize in a perovskite phase with fine, equiaxed grains. The NN films e...

Sodium zirconate (Na2ZrO3) was tested as a basic catalyst for the production of biodiesel using a soybean oil transesterification reaction. Initially, Na2ZrO3 was synthesized via a solid-state reaction. The structure and microstructure of the catalyst were characterized using X-ray diffraction, ...

The sodium oxide activity established by the equilibrium between Na2ZrO3(s) and ZrO2(s) is subject to a continual change upon varying the composition of the phase mixture. This is revealed from the results of a solid state electrochemical approach that allows sensitive differentiation between un...

NiO-doped sodium zirconate ceramics with different amounts of NiO (between 0 and 10 wt%) were synthetized and characterized by powder XRD, SEM-EDS and N2 physisorption. Structural and microstructural characteristics of a Na2ZrO3 based-ceramic were maintained in all NiO-containing samples. These ...

The dielectric, piezoelectric, and electromechanical properties of B-site cobalt-modified sodium lanthanum bismuth titanate (Na0.5La0.5Bi4Ti4O15, NLBT) piezoelectric ceramics were investigated. The piezoelectric properties of NLBT ceramics can be enhanced by cobalt modifications. The NLBT cerami...

There have been an increasing interest in finding a replacement for the chromating process due to environmental and health concerns. Hence, in this study Chrome-free chemical conversion coatings were deposited on the surface of cold-rolled steel (CRS) on the basis of Titanium (TiCC), Titanium-Ni...

Nanoparticle amorphous lanthanum borate with a particle size of 20–40 nm was prepared with a Replacing Solvent Dry technique and characterized using TEM and XRD. Its tribological properties as a wear resistance additive of lubricating oil were evaluated with a four-ball tribotester. The wear sc...

Lanthanum-doped titanium-zirconium-molybdenum (La-TZM) alloy was prepared by powder metallurgy and rolling process. The processing crack and crack initiation mechanisms of La-TZM alloy after sintering, hot rolling and cold rolling were studied by scanning and transmission electron microscopy. Th...

Pure natural cellulose (softwood pulp) modified with cellulase is allowed to react with sodium hydroxide in a muller, and changes in structure and properties are investigated by FTIR and DSC. The reactivity of cellulose for some dissolving and derivatization processes is shown to be improved by ...

The electrochemical behavior of lithium in lithium hydroxide solution with sodium nitrite has been investigated in this paper. The results show that the hydrogen evolution rate decreases with increasing sodium nitrite concentration. Through potentiostatic polarization and scanning electron micro...

Increase in industrialization as a tool to become global leader has led to an exponential rise in environmental pollution. The present study describes a process developed to extract nanocrystalline sodium carbonate from chemical industry effluents, which contributes to wealth creation from hazar...

A novel polymeric sodium tartaric acid borate is synthesized and blended with poly(vinylene carbonate) to prepare a single-ion conducting gel polymer electrolyte (PSP-GPE). The PSP-GPE possesses a superior ionic conductivity of 1 × 10−4 S cm−1 at ambient temperature and a high sodium ion transf...

The development of hydrazine monohydrate (N2H4·H2O) as a viable hydrogen carrier requires high-performance and cost-effective catalysts for selectively promoting its decomposition to generate hydrogen at mild conditions. Herein, we report the synthesis of a non-precious metal nanocatalyst, in b...

In this work, partially dehydrated zinc hydroxide sulfate nanoplates are synthesized by facile chemical bath deposition together with subsequent heat dehydration.
