Superior electrochemical behavior for nickel-cobalt sulfide electrodes must be researched and improved. For the storage of energy in supercapacitors, this work, the NiCo 2 S 4 /Ni/Ni 9 S 8 nanostructure composite (NCS/N/NS) was created using a solvothermal technique using PEI as a carbon source, followed by argon atmosphere annealing at 500 °C for an hour, followed by a hydrothermal method using thiourea as a sulfur and nitrogen source. NCS/N/NS supplies exceptional electrochemical energy storage features. When used for SCs, the manufactured electrode material, NCS/N/NS, revealed at 1 Ag −1 a superb capacitance of 1620 Fg −1 (696 Cg −1 ). An NCS/N/NS//activated carbon (AC) asymmetric device was created for practical use by utilizing an NCS/N/NS as the positively charged electrode and the opposite electrode of commercial AC. The asymmetric device achieved a unique specific energy of 53 Wh kg −1 , with a specific power of 887 W kg −1 at 1 Ag −1 .
必须研究和改进硫化镍钴电极的优异电化学性能。为了在超级电容器中储存能量，本研究以聚乙烯醇（PEI）为碳源，采用溶热技术制备了镍钴硫化镍（NiCo 2 S 4 /Ni/Ni 9 S 8）纳米结构复合材料（NCS/N/NS），然后在 500 °C 的氩气环境下退火一小时，再以硫脲为硫源和氮源进行水热法处理。NCS/N/NS 具有优异的电化学储能特性。当用于储能电池时，NCS/N/NS 制成的电极材料在 1 Ag -1 的条件下显示出 1620 Fg -1 （696 Cg -1 ）的超强电容。通过使用 NCS/NS 作为带正电的电极和商用 AC 的对电极，创建了一个 NCS/NS// 活性碳 (AC) 不对称装置，并投入实际使用。该非对称装置实现了 53 Wh kg -1 的独特比能量，在 1 Ag -1 时的比功率为 887 W kg -1 。

The sustainable development goals (SDGs) for the United Nations are the main factors that determine and form the future of industry and economy global wise. Green industry is the key word in any new investment and economic project, which makes the investors working for upgrading and developing the ongoing industries in order to fit with SDGs requirements and principles from one side and to keep the line of following the sustainability requirements for the new projects from the other side. Metallurgical industries are considered the most changing industries to follow sustainability boundaries and SDGs due to the huge amount of natural resources used (raw materials and ores), huge amount o energy (mostly fossil energy) and a plenty of required water. One of the important measures for sustainability as it affects safety and health of labors is the noise. Noise affects the health of workers and can be reason of fatal incidents and be a source of economic drawback in such heavy industry. This article clarifies the research work to evaluate the noise at steel plant and how it’ll be studies and consider the methodology to overcome the harms results from it in way to help such important industry to be eco-friendly and sustainable.

This work aims to prepare perovskite zinc stannate (ZnSnO 3 ) by the sol-gel method and to study the electrochemical properties. This performance improves by adding different percentages of naturally prepared activated carbon from pomegranate peels. ZnSnO 3 is considered an attractive cathode material for energy storage, which shows a specific capacitance of 115 F g -1 at 1 A g -1 , while the optimum added percentage of the activated carbon is 5%AC+95%ZnSnO 3 , which exhibits 312.5 F g -1 at the same current density, which considered about three times more than that of the ZnSnO 3 , with capacitance retention of 66% after 2000 cycles at the current density of 10 A g -1 . The practical hybrid device shows a specific capacitance value of 61.6 F g -1 at 1 A g -1 , the specific energy of 22 Wh kg -1, and specific power of 1077 W kg -1 with capacitance retention of 50% of the initial capacitance after 2000 cycles at a current density of 10 A g -1 . As a result, ZnSnO 3 and its composite with cheap and natural materials are considered promising supercapacitor electrodes. The Nyquist plots show a semicircle in the high-frequency region and a near-vertical line at low frequency. The near-vertical line in the low-frequency region indicates the good capacitive of the composite electrode.
采用溶胶-凝胶法制备钙钛矿锡酸锌(znsno3)，并对其电化学性能进行研究。通过添加不同百分比的石榴皮天然活性炭来提高这种性能。ZnSnO 3被认为是一个有吸引力的阴极材料能量储存,展示了一个特定的电容115 F 1 g 1 g 1,而活性炭的最佳添加比例是5% ac + 95% ZnSnO 3,展品312.5 F g 1在同一电流密度,这被认为是大约三倍的ZnSnO 3,与电容保留66%的2000次后10 g 1的电流密度。实际混合器件在1 a g -1时的比电容值为61.6 F g -1，比能量为22 Wh kg -1，比功率为1077 W kg -1，电流密度为10 a g -1，循环2000次后电容保持率为初始电容的50%。因此，znsno3及其与廉价和天然材料的复合材料被认为是有前途的超级电容器电极。奈奎斯特图在高频区呈半圆形，在低频区呈近似垂直线。低频区近似垂直线表明复合电极具有良好的电容性。
