Primarily owing to the increased a doption in consumer electronics, th e demand for supercapacitors increased significantly over the past few years. While Samsung’s Galaxy Note 9 came with a nifty new feature: the S Pen stylus Bluetooth, and could be charged instantly using a supercapacitor, several smartphone manufacturers invested in next-gen battery design to better protect against drops and weath er condi tions tha t drove the growth of smartphon e supercapacitors.  Moreover, with automotive manufacturers emphasizing on reducing dependency on the oil sector and governing bodies imposing stringent environmental regulations, growth prospects for the el ectric vehicles is expected to be promising. This has led the supercapacitor manufacturers to explore profitable opportunities in the rapidly-evolving automotive industry. Due to this, in February 2019, Tesla Inc., a global giant in the automotive and energy industries, acquired Maxwell Technologies Inc., a leading battery technology company for approximately USD 218 million. Following this acquisition, the company aimed to capitalize on lucrative opportunities for electric vehicles, and it planned to add expertise in the field of supercapacitors that could speed up car charging capabilities.

Increasing demand for low calorie sweeteners from food and beverages manufacturers have been increased from last few years, owing to the rising concern over obesity and diabetes across the world. Many key players in beverages are introducing the products with natural low-calorie sweeteners mainly stevia.  For instance, in 2018, Coca-Cola launched Coke “Coca-Cola Life” sweetened with 100% stevia in New Zealand. The company is also planning to introduce this product in the South Pacific region in upcoming years.  Increasingly, consumers from developed economies such as the United States, Germany, and the United Kingdom are inclined toward low-sugar fruits and vegetable juices, which is driving the demand of stevia for beverages application.

In sports management, software has become a key differentiator to gain a competitive advantage for the stakeholders in the sports industry. Hence, many sports associations, clubs, and their coaches have been adopting the all-in-one integrated software solution driving the growth of the global sports management software market. Furthermore, companies in the global sports management software market are providing customized modules of the sports management software and pay as you go model in cloud deployment, which is driving the growth of the market. In the study, the technological aspects, along with the market trends, have been analyzed covering the use of sports management software across various applications.

Soft magnetic material are those materials that are easily magnetized and demagnetized and are known for having intrinsic coercivity less than 1000 Am. Soft magnetic material is known for enhance and channel the flux produced by electric current. Material considered under includes nickel, cobalt, iron, electric steel, soft ferrite, and their alloys. These material are used in both AC and DC applications. In DC applications, the material is magnetized to perform an operation and then demagnetized at the end of the operation. While, in AC applications, material is continuously cycled and being magnetized in one direction to other throughout the period of application. This is one of the major advantages that the soft magnetic material has over hard magnetic material.
