World’s first graphene-applied lead-acid battery mass produced in Sri Lanka

Graphene is the world's thinnest substance, and its interesting features have made it popular. "Graphene, for example, is 100 times stronger than the finest steel and 100 times stronger than diamond. It is durable, adaptable, and transparent. It is utilized to produce miniaturized, super-fast computers and transistors because it conducts so much electricity in such a small space." In 2017, mining and quarrying contributed roughly 2.7 percent of Sri Lanka's GDP. "Graphene is renowned as the world's newest breakthrough substance, and increased exports might treble present export revenue." Sri Lanka is the only country in the world that produces vein graphite, which has been mined for over two centuries and is called locally as 'Miniran.' For more than a century, Sri Lanka has been the world's only country to harvest ultra-pure extremely crystalline vein graphite with more than 98 percent carbon purity. Currently, Sri Lanka produces only 300 ton

Only Asian ground where Sir Don Bradman played- Paikiasothy Saravanamuttu Stadium - Srilanka

The Tigers made it a memorable occasion by winning by four wickets. It's safe to say that P Sara Oval will live on in the hearts and imaginations of Bangladesh fans for the rest of their lives. The stadium is especially significant since it is the only Asian site where Sir Don Bradman, cricket's greatest player of all time, has appeared. Despite the fact that Bradman never toured South Africa, India, New Zealand, or the West Indies, he did play in Sri Lanka twice, with the island serving as a stopover for Australian teams on their way to England for many years. On one of the walls in Mahadevan Sathasivam stand, on the south side of the ground, is a photograph of Bradman walking out for the toss with Ceylon captain Mahadevan Sathasivam. Sir Don Bradman's "Invincibles" were travelling England for the 1948 Ashes with Mahadevan Sathasivam Bradman's Ceylon XI captain. On their way to England, Australia paused for a few days on the island and played a three-day matc

Oldest Radio Station in Asia (world’s second oldest)-Radio Ceylon - Srilanka

Sri Lanka possesses Asia's (and the world's) oldest radio station. Radio Ceylon used to be the name of the station. It grew into one of the world's most prestigious broadcasting institutions. The Sri Lanka Broadcasting Corporation is now the name of the company. When the Telegraph Department began broadcasting in Ceylon on an experimental basis in 1923, just three years after broadcasting in Europe, Sri Lanka made Asian broadcasting history. A modest transmitter created by Telegraph Department engineers using the radio equipment of a captured German submarine was used to broadcast gramophone music from a tiny chamber in the Central Telegraph Office. This radio trial was a big success, and a regular broadcasting service was established only three years later, on December 16, 1925. Edward Harper, who arrived in Ceylon in 1921 as Chief Engineer of the Telegraph Office, was the first person in the country to actively push radio. With broadcasting services launched just thre

Highest density of wild leopards in the world - Sri Lanka's Yala National Park

There are 26 national parks and two marine parks in Sri Lanka. Yala National Park is known for having the world's highest population of wild leopards as well as the world's largest leopards. According to reports, there is one leopard every square kilometer in one region of the Park, a staggeringly high amount when compared to anywhere else on the planet. According to unconfirmed sources, Sri Lanka has between 500 and 650 leopards in the wild. Sri Lankan Leopards can also be found in the much bigger Wilpattu National Park, Sri Lanka's largest. Although not as densely inhabited with leopards as Yala, the whole acreage of this National Park suggests that there may be a significant number of these large cats there. Leopard sightings are similarly uncommon in Sri Lanka's other national parks, as leopards prefer to avoid human settlements. During a visit to Yala, expect to observe grouchy bachelor male elephants during the dry season and enormous herds during the rainy

First country in South Asia to recycle compact fluorescent lamps - Srilanka

  Sri Lanka is setting an example at a time when developing countries are grappling with the safe disposal of compact fluorescent lights (CFLs). Pitipana, a small hamlet 35 kilometers from Colombo, is home to Asia Recycling, South Asia's first CFL recycling plant. Orange Electric, which has a 48 percent local market share in CFLS, owns the plant. The plant can recycle up to 30 million CFLs each year, which is approximately three times the yearly usage in Sri Lanka. The plant was built in collaboration with Swedish recycling company Nordic Recycling AB. The facility collects CFL trash from banks, schools, and universities, as well as enterprises, hospitals, and government offices. CFL garbage should be disposed of at specified collection centers by households. CFLs are gathered and assembled at the Pitipana factory before being recycled. The recycling process involves fifteen individuals. The components of a CFL are first manually separated. The mercury recovery technology (MRT

The oldest human planted tree in the world - JAYA SRI MAHA BODHI

The oldest tree known to have been planted by humans rather than natural sowing is a 2,300-year-old sacred fig or bo-tree (Ficus religiosa) in Anuradhapura, Sri Lanka, known as Sri Maha Bodhiya. It was planted there around 288 BC. The mother tree from which this specimen was reproduced was none other than the famed Bodhi tree, under which Siddhartha Gautama, the Lord Buddha, sat when he attained enlightenment. Naturally, because of its spiritual importance, the Jaya Sri Maha Bodhi holds a special place in the hearts of the world's Buddhists, particularly those in Sri Lanka. Every year, Buddhists from all over the world come to visit and pay their respects to one of the most precious ancient relics of the Buddhist faith. According to history, Sangamitte Theri, daughter of Emperor Asoka, transported the tree all the way from India to Sri Lanka in the 3rd century BC. Sangmitta established her own order of Buddhist nuns in her native Sri Lanka. The tree was then officially planted by K
