LG Chem & Japan's Noritake unveil heat-resistant silver paste
LG Chem announced today that it has co-developed a high- performance silver paste with Japan's Noritake, designed specifically for bonding silicon carbide (SiC) chips to substrates in automotive power semiconductors.
LG Chem and Noritake co-developed a high-performance silver paste for bonding SiC chips in automotive power semiconductors. The paste, combining LG's particle tech and Noritake's dispersion expertise, offers superior heat resistance, thermal conductivity, and room-temp stability. The market may grow from KRW 300B in 2025 to KRW 850B by 2030 as EV and autonomous tech demand rises.
Noritake is a leading Japanese company with over 120 years of expertise in advanced ceramics, supplying grinding wheels, materials for electronic components, and kilns (thermal processing equipment) for applications in the semiconductor and automotive industries.
As the automotive electrification and autonomous driving technologies experience a rising trend, the demand for power semiconductors is growing rapidly. However, traditional soldering methods, which rely on melting metals to join components, have become less effective as the operating temperatures of power devices increase. This has created a growing need for paste that can maintain stability and performance under high thermal conditions.
The silver paste co-developed by LG Chem and Noritake is a high-performance paste containing nano-sized silver (Ag) particles, combining LG Chem's particle engineering technology with Noritake's particle dispersion expertise. The two companies achieved superior heat resistance and thermal conductivity in a single formulation.
Unlike conventional silver pastes, which require cold storage and have a short storage life that complicates inventory management, the new product offers long-term stability at room temperature. This improvement enhances transportation and storage efficiency, while also extending the usable time within customer processes—ultimately reducing material loss.
Building on this successful collaboration, LG Chem and Noritake plan to pursue further joint development of next-generation materials for future automotive applications.
The global silver paste market for automotive power semiconductors is expected to grow from KRW 300 billion in 2025 to KRW 850 billion by 2030.
'Leveraging our accumulated technological expertise and advanced materials design capabilities, LG Chem has provided customized solutions across various industries, including automotive electronics,' said Shin Hak-Cheol, CEO of LG Chem. 'Through our partnership with Noritake, we aim to strengthen our differentiated competitiveness in the global automotive materials market.'

Osaka Gas India expands rapidly, eyes sustainable growth and clean energy future
Osaka [Japan], June 16 (ANI): Japanese energy giant Osaka Gas, established in 1987, is making significant strides in India's energy sector. With a legacy of expertise in gas production, supply, and pipeline infrastructure, the company also maintains a strong presence in electricity generation. Following successful expansions across Asia, the United States, and Australia, Osaka Gas launched its Indian subsidiary, Osaka Gas India, in 2021. Now, four years later, the company is charting an ambitious course for clean and sustainable energy in the country. In an exclusive interview, Takeshi Shinohara, Managing Director of Osaka Gas India, reflected on the company's journey and expanding role in the Indian energy landscape. 'In just four years, Osaka Gas India's operational area has expanded to cover 10% of India's land--roughly equivalent to the size of Japan,' said Shinohara. In India, Osaka Gas is actively engaged in city gas supply and pipeline construction, working in partnership with Chennai-based firm Think Gas. This collaboration has enabled the rapid development of urban gas infrastructure and ensured efficient energy distribution. The company's long-term vision for India rests on three foundational pillars. The first is its traditional strength in city gas operations. The second is a growing focus on renewable energy. In partnership with Indian clean energy leader CleanMax, Osaka Gas India is generating electricity through solar and wind power, serving industrial clients that demand environmentally sustainable energy. 'Our success so far has been made possible through strong partnerships with trusted Indian companies,' Shinohara noted. The third and most forward-looking pillar is E-Methane, a clean fuel alternative combining city gas with hydrogen derived from renewable sources. This innovative approach results in a circulative energy model that dramatically reduces carbon emissions. 'By combining city gas with hydrogen derived from renewable energy sources, E-Methane offers a sustainable, circulative energy solution that significantly reduces CO2 emissions,' said Shinohara. Shinohara emphasized that India's economic momentum and social transformation are fueling demand for smarter, greener energy options. 'India's rising economic power and dynamic society will drive increasing demand for cleaner and more efficient energy solutions in the coming years,' he said. Unlike passive financial investors, Osaka Gas operates with a 'hands-on' philosophy, committed to transferring technical knowledge and building long-term capabilities within India. 'Real Scene, Real Material, Reality,' Shinohara stated, describing the company's core principles. 'This reflects our deep commitment to operational excellence and grounded experience.' Looking ahead, Osaka Gas sees India as an integral part of its global future. 'By 2030, India will become a major pillar of Osaka Gas's global business,' he predicted. Yet, Shinohara also highlighted the stark developmental contrasts between India's urban centers and rural heartlands, particularly in agricultural regions. 'Osaka Gas India aims for real symbiosis with Indian society by combining our global experience with local understanding,' he concluded. As India undergoes a profound transformation in its energy landscape, Osaka Gas India's integrated approach--grounded in innovation, collaboration, and sustainability--could play a pivotal role in shaping the country's clean energy future.

Viral: Man reveals one aspect where Indian salons lag behind Japanese ones and it is not their service
Image credits: X/@BarkusMaximus Globalisation and new money have allowed us a world of experiences which one could only dream of earlier. Nowadays, it isn't difficult for most people to pack a bag and get set to explore the world. People travel across the globe and enjoy the minute pleasures of life, such as getting a haircut in a different country. Hair salons in various countries offer unique experiences and men all around the world are surely attracted to them. From unique haircuts to massages, salons experiment with a lot of services to keep a constant revolving door of customers. However, is that enough? Recently, a man took to X to share the only difference between a Japanese and Indian salon, which he thought was good PR. Referencing a video of a man getting a haircut in Japan where he suggested that it is an experience every man should get once in their lifetime, he wrote, "Japan's PR is unreal just like 'Peak Bengaluru'. There is absolutely nothing in this clip which my barber from my current hometown wouldn't be doing for ₹250-300. " The video showed a female barber cutting a man's hair which involved a haircut, hair wash, facial, face shaving, and lots of massage on the head, shoulder and back. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Recibirás alertas gratuitas sobre acciones con este nuevo algoritmo TradeTrend Más información Undo Netizens react Image credits: X/@BarkusMaximus The comparison is actually true. If you see videos of Indian salons giving haircuts to men, all of these acts are involved but the only difference is that the entire activity is not sold as one big life-changing experience. People in the comments attested to the man's views writing, "Absolutely agree. The day we nail Aesthetics we rule the world." "My barber Shahrukh bhai does it for Rs 150." quipped another X user. Image credits: X/@BarkusMaximus Many wrote how cleanliness and calmness were a factor that differentiated the salons of the two countries. The Indian salons market hair cutting as a service which is performed in a short and quick amount of time and you are one of the many customers in line. However, Japanese salons market haircuts as a personal experience where you can rest and enjoy a service catered to you in particular. "Feel her stillness and calmness. Our barbers are in a different haste." and "Cleanliness and respect, not an everyday concept or expectation in India any more" wrote people in the comments. "The word you need to focus upon is 'experience' one pointed out. Others added the unique aspects of Indian salons that Japanese salons can't replicate, which is a haircut and massage with classic Indian songs playing in the background. "Mere yahan 50 mein kaat deta hai World class hairstyle Massage and Kumar Sanu bangers are added extras" and "But with old melodies, geopolitics and gossip of the town..." shared some.

G7 meets under global fire: Trump pushes trade as leaders urge de-escalation in Middle East
But as Trump met with Canadian Prime Minister Mark Carney, he also stressed it was a mistake to remove Russia from the organisation in 2014 and doing so had destabilised the world. He also suggested it would be a good idea to add China to the G7. The US president also seemed to put a greater priority on his planned emphasis on addressing his grievances with other nations' trade policies. 'Our primary focus will be trade,' Trump said of his talks with Carney. This year's G7 summit is full of combustible tensions, and it's unclear how the gathered world leaders can work together to resolve them. Trump already has hit several dozen nations with severe tariffs that risk a global economic slowdown. There is little progress on settling the wars in Ukraine and Gaza, and now a new conflict between Israel and Iran. Add to all of that the problems of climate change, immigration, drug trafficking, new technologies such as artificial intelligence and China's continued manufacturing superiority and chokehold on key supply chains. "We're gathering at one of those turning points in history," Carney said. "The world's more divided and dangerous.' But as the news media was escorted from the opening session, Carney could be heard as he turned to Trump and referenced how his remarks about the Middle East, Russia and China had already drawn attention to the summit. 'Mr. President, I think you've answered a lot of questions already,' Carney said. Trump wants to focus on trade, though he may have to balance those issues with the broader need by the G7 countries — which also include France, Italy and Japan — to project a united front to calm down a world increasingly engulfed in chaos. Asked if he planned to announce any trade agreements at the G7 as he left the White House on Sunday, Trump said: 'We have our trade deals. All we have to do is send a letter, 'This is what you're going to have to pay.' But I think we'll have a few, few new trade deals." Also at stake might be the survival of the G7 itself when the Trump administration has sent mixed signals about whether the president will attend the November Group of 20 summit in South Africa. The German, UK, Japanese and Italian governments have each signalled a belief that a friendly relationship with Trump this year can help to keep any public drama at a minimum, after the US president in 2018 opposed a joint communique when the G7 summit was last held in Canada.
