“…Electrodeposition of Co(OH) 2 nanostructures eventually lead to great increase in the specific capacitance and energy density of supercapacitor electrode. Research results confirmed the excellent supercapacitive behavior of Co(OH)2-ECF as electrode material for supercapacitor applications [16].…”

With world-wide strict legislation for reduction or removal of lead from industrial waste, development of a large number of lead-free alternative solder materials had been intensively examined. The drive for lead-free solders development was towards systems that can imitate conventional lead containing solder alloys in terms of melting temperatures and improvement of mechanical properties. Nanostructured solder alloy, with a grain size of typically < 100 nm, was a new class of materials with properties distinct from and frequently distinguished to those of the conventional alloy. In comparison, nanostructured solder alloys exhibit higher strength and hardness, enhanced diffusivity, and excellent soft and hard magnetic properties. Numerous different techniques were performed to synthesize these nanostructured solder alloys. Electrodeposition method has generated huge interest in nanostructured solder preparation, mainly due to its ability to deposit solders selectively and uniformly at nanoscale. These factors bring significant influences on the behaviors of products, such as magnetization, density, ductility, wear resistance, corrosion resistance, porosity, molecular structure, and crystal properties which plays a vital part in the field of electronic manufacturing. In this paper, a short review on the electrodeposition, a useful technique to deposit different metals and alloys, as a method for nanostructured lead-free solder alloys preparation is presented.

“…Based on previous studies, this morphology change usually indicates electrolyzed carbon. 62,63 Therefore, the instability of MCN/ LDH-1.5 mixture can be attributed to carbon corrosion during battery recharging. The lack of interaction between MCN and LDH in MCN/LDH-1.5 physical mixture may cause the applied recharging voltage more favorable to the carbon oxidation instead of OER, and the battery assembly eventually failed because of air electrode degradation.…”

The lack of efficient and durable bifunctional cathodic catalysts largely prevents the wide-scale applications of rechargeable Zn–air batteries (RZABs). Herein, we report a bifunctional, durable, and noble-metal-free electrocatalyst for RZABs by compositing a metal–organic framework (MOF) derived carbon network (MCN) and NiFe-layered double hydroxide (LDH) nanoplates. This design utilizes the conductivity and ultrahigh pore volume of the carbon network, boosting the catalytic activity of LDH and enhancing the catalytic durability in both half-cell measurements and RZAB assemblies. The RZAB with our MCN-LDH catalyst can discharge and recharge consistently at a current density of 10 mA cm–2 for at least 5 days, tripling the life hour of RZAB with noble metal catalysts.

“…Depending on the charge-storage mechanisms, supercapacitors are generally classied into two major types: carbon based electrical double-layer capacitor (EDLC) and faradaic capacitor. [5][6][7][8][9][10][11][12] It was already reported that the size and morphology of Co 3 O 4 extremely affect its electrochemical performance and therefore many researchers are attempting fabricate it in newer shapes and morphology in nanoscale dimensions. Different nanoscale morphologies such as hollow nanospheres, cubic single crystals, bers, particles, rods, tubes and lms in nanoscale have been reported so far.…”
