A promising alternative route for the synthesis of three-dimensional Au dendrites was developed by direct electrodeposition from a solution of HAuCl4 containing 3-aminopropyltriethoxysilane (APTS). Ultraviolet-visible spectroscopy, fourier transform infrared spectroscopy and isothermal titration calorimetry were used to study the interaction of APTS in electrolyte. The effect of APTS on the for...

Herein, we studied the effect of MgO coating thickness on the performance of printable perovskite solar cells (PSCs) by varying the electrodeposition time of Mg(OH)2 on the fluorine-doped tin oxide (FTO)/TiO2 electrode. Electrodeposited Mg(OH)2 in the electrode was confirmed by energy dispersive X-ray (EDX) analysis and scanning electron microscopic (SEM) images. The performance of printable PS...

Metal electrodeposition may introduce various morphological variations depending on the electrolytic conditions including cell configurations. For liquid electrolytes, a precise study of these deposits may be complicated by convective motion due to buoyancy. Zero-gravity (0-G) condition provided by drop shaft or parabolic flight gives a straightforward mean to avoid this effect: we present here...

There is a renewed interest in the field of thermoelectrics because of the remarkable efficiency improvement that can be achieved in nanostructured materials, for example, superlattice thin films and quantum dots. Theoretical calculations predict that further enhancement of the thermoelectric figure of merit can be achieved in superlattice nanowires (zero-dimensional) [5] rather than convention...

Here we demonstrate progress on electrodeposition of photoactive silicon films from an environmentally friendly molten CaCl2 electrolyte, which is the first step of a new route to a practical low-cost silicon solar cell. We report electrodeposition of severalmicron thick silicon films on a graphite substrate in a bath of molten CaCl2 containing SiO2 nanoparticles. The best silicon deposits was ...

Reversible dendrite-free low-areal-capacity lithium metal electrodes have recently been revived, because of their pivotal role in developing beyond lithium ion batteries. However, there have been no reports of reversible dendrite-free high-areal-capacity lithium metal electrodes. Here we report on a strategy to realize unprecedented stable cycling of lithium electrodeposition/stripping with a h...

Nanoelectrode ensembles (NEEs) have been fabricated by the electrodeposition of Au nanoparticles (AuNPs) on single-layer graphene oxide (GO) sheets coated on a glassy carbon electrode (GCE). The fabricated NEEs show a typical sigmoidal shaped voltammetric profile, arising from the low coverage density of AuNPs on GCE and large distance among them, which can be easily controlled by varying the e...

The electrodeposition of Ni–Co alloy from a nickel Watt’s solution in the absence and presence of a permanent parallel magnetic field (PPMF) to the plane of deposition (perpendicular to direction of current) produced a deposited layer with mostly fine grain structure. The deposited layers have been characterized by scanning electron microscopy (SEM) and energy dispersive X-ray (EDX). It was fou...

The determination of cholesterol is increasingly important for the fact that high serum cholesterol level was related with many diseases. In this work, a new cholesterol biosensor was developed based on the gold-graphene nanocomposite material prepared by one-step electrodeposition. The nanomaterial formed on a glassy carbon electrode was proved by scanning electron microscope and the electroch...
