Tamil Nadu twins build machine ‘Shield-X' to sterilise everyday objects

India Today11-07-2025
A pair of twin brothers from Tamil Nadu have designed and patented a new sterilisation machine aimed at promoting personal hygiene, inspired by the widespread impact of the Covid-19 pandemic. Named 'Shield-X', the device is intended to disinfect everyday personal belongings and reduce the spread of harmful pathogens in public and private spaces.The inventors, Ramnath and Laxmanakanth from Salem, said their motivation stemmed from witnessing the devastation caused by the pandemic and the need for accessible hygiene solutions. 'We faced major loss of life due to the Covid-19 pandemic, life loss caused not by war or natural calamity but by pathogens. Though we maintained social distancing, one way for such pathogens to stay around was due to our neglect to keep items that we use everyday clean and even if such a product had to be used, it was not affordable. This led to us creating the Shield-X chamber as a way to remind the public about keeping their day-to-day used products clean and sterile,' said Laxmanakanth.advertisementThe Shield-X machine has been designed with four distinct modes of sterilisation, tailored to the type of object being cleaned. 'We have initially created the machine with four modes sterilisation which includes, UV-sterilisation where 89-2100 nm UV light will be used, then thermal disinfectant, third is fogging treatment where we have worked on a chemical composition and final process fume extraction where hot, dry air is used to sterilise. Based on the items, the sterilisation process varies. Cellphones are objects which we use regularly but we never clean and so for sterilising smartphones we can use UV treatment for 30 seconds, while for an object like a helmet, we will have to use all four methods of cleaning which can be done in 4 minutes,' explained Ramnath.
The brothers believe that the Shield-X chamber can be seamlessly integrated into a variety of environments. 'The machine is designed in such a manner that it can also be used like a vending machine and is app compatible,' said Ramnath. They added that the machine can be installed in educational institutions, corporate offices, and public spaces, offering a practical and automated solution to help keep commonly used items sterile.- Ends

The airport lounge war has begun — and DreamFolks is losing

Around three years ago, as India's airlines and airports were trying hard to leave the nightmares of the Covid-19 pandemic behind, one travel-technology entrepreneur, Liberatha Peter Kallat of DreamFolks, was out selling another kind of a dream. The firm, an aggregator that acts as a go-between for airport lounge operators, payment networks like American Express, Visa, and MasterCard, and the passengers who swipe their cards for a quick bite or

PGI's Rs 490 cr Advanced Neuroscience Centre nears launch by Sept

Chandigarh: India's healthcare system, currently facing a critical shortage of neurologists—with just one specialist available per million people—is on the brink of a major breakthrough. The Postgraduate Institute of Medical Education and Research (PGI), Chandigarh, is preparing to launch its long-awaited Advanced Neuroscience Centre, a Rs 490 crore project that promises to revolutionise neurological and neurosurgical care across the country. Approved in 2017 and with construction beginning in 2020, the centre is now nearing full operationalisation. PGI officials have confirmed that the outpatient department (OPD) is expected to become functional by September, marking a significant milestone in the journey to improve access to specialised brain and spine treatment. Once fully operational, the centre will join the ranks of premier institutions like NIMHANS Bengaluru and AIIMS Delhi's Cardiothoracic and Neurosciences Centre. However, PGI's facility stands out for its integrated model, combining neurology and neurosurgery services under one roof. "This will be the largest such centre in India where both specialities are housed in a single building," said a PGI official. "Beds will be consolidated, not scattered across departments, ensuring seamless care for patients. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Access all TV channels anywhere, anytime Techno Mag Learn More Undo " The project has faced several hurdles over the years. Construction was halted during the Covid pandemic in March, 2020 and resumed with limited labour by June. More recently, delays were caused by the renewal of pollution control clearance from the state pollution control board and the calculation of property tax arrears owed by PGI. Despite these challenges, the administration remains optimistic about the centre's phased rollout. The facility will feature 300 general ward beds, 10 modular operating theatres, dedicated ICUs, 10 High Dependency Unit (HDU) beds, and 30 private ward beds. It will offer advanced sub-specialities such as cerebrovascular surgery, skull base surgery, and spinal functional neurosurgery. A key highlight is the Brain Suite, a specialised operating room designed for complex neurosurgical procedures. While some equipment requests—like a 3T MRI, Bi-plane DSA, and dual-energy CT scan—were scaled down due to budget constraints, PGI faculty believe the centre will still significantly enhance diagnostic and treatment capabilities. "Patients come from all corners of India because of the expertise and affordability PGI offers," said a senior faculty member. The Advanced Neuroscience Centre is expected to serve as a national hub for neurological care, addressing a long-standing gap in specialised treatment. With its integrated approach and cutting-edge infrastructure, the centre is poised to offer a lifeline to thousands of patients who currently struggle to access timely and affordable brain and spine care.

Indian semiconductor market may grow over two-fold to Rs 9.6 lakh crore by 2030

ETtech India's semiconductor market is expected to more than double to grow in the range of $100-110 billion by 2030 according to industry estimates, an official statement said on Sunday. The Indian semiconductor market was about $45-50 billion in 2024-2025 against $38 billion in 2023, the statement said, citing industry estimates. "As per industry estimates, the size of the Indian semiconductor market was about $38 billion in 2023, $45-50 billion in 2024-2025 and is expected to reach $100-110 billion by 2030," the statement said. A detailed statement highlighting the need for semiconductors, efforts of the government and response from the industry cited the crisis faced by various technology segments especially by the automobile industry due to dependency on select geographies during the Covid pandemic and stressed on the need for developing India as trusted partner in the global supply chain. "Currently, countries like Taiwan, South Korea, Japan, China and US dominate the semiconductor industry. Taiwan produces more than 60% of the world's semiconductors, including nearly 90% of the most advanced ones. "Such dependence on a single region has exposed global supply chains to significant risks - from pandemics and natural disasters to geopolitical tensions. Recognizing this challenge, many countries are now building secure and diversified supply chains," the statement said. The United States, European Union, Japan, and South Korea have launched national strategies to support domestic chip manufacturing and reduce over-reliance on a single region. "India is emerging as an important and trusted partner in this global shift," the statement said. The global semiconductor market is expected to reach $1 trillion by 2030, with India's market occupying a substantial portion of it. India has the capacity to emerge as a key contributor to the three primary pillars of the semiconductor manufacturing supply chain - equipment, materials and services and R&D. It stated that India can leverage a strong base of MSMEs to produce components for semiconductor equipment and it has a rich source of chemicals, minerals and gases which can be utilised by semiconductor supply chain companies. Services R&D, logistics and supply chain, major talent in AI, big data, cloud computing and IoT are major strengths, the statement said. The government has already launched India Semiconductor Mission in December 2021 with an outlay of Rs 76,000 crore to provide financial support for investments in semiconductor fabrication, display manufacturing & chip design to strengthen India's integration into global electronics value chains. Industry players including US memory chip maker Micron, Tata Electronics (TEPL) in partnership with Powerchip Semiconductor Manufacturing Corp (PSMC) of Taiwan, CG Power & Industrial Pvt Ltd in partnership with Renesas & Stars, Tata Semiconductor Assembly and Test Pvt Ltd (TSAT), Kaynes Semicon, HCL-Foxconn JV have committed a total investment of over Rs 1.55 lakh crore to produce semiconductors in India. The government under the ISM has made a Rs 1000 crore provision for Design Linked Incentive for chip design out of which it has committed Rs 234 crore financial support for eligible start-ups. "The government had committed the support of Rs 234 crore for the chip design projects from 22 companies with a total project cost of Rs 690 crore. These chips will be used in CCTV cameras, mobile networks, satellites, cars, smart devices, etc. The government under its vision for semiconductor ecosystem development supports Semicon India which is a flagship event organised in partnership with SEMI (Semiconductor Equipment and Materials International). The platform brings together global industry leaders, policymakers, academia, and startups to foster investment, dialogue, and strategic partnerships. "The 4th edition is to be held in Delhi from September 2-4th, 2025. Semicon India 2025 co-hosted by India Semiconductor Mission (ISM) and SEMI will be held from September 2-4, 2025, at Yashobhoomi (IICC), New Delhi. It is set to display India's redefining role in the global semiconductor ecosystem," the statement said. Elevate your knowledge and leadership skills at a cost cheaper than your daily tea.
