LG's Advanced Refrigerator Technology Delivers Superior Summer Performance When It Matters Most
LG Electronics (LG) is keeping condiments and crunchables as cool as a cucumber with its comprehensive range of French door refrigerators, featuring cutting-edge technology for exceptional performance and convenience throughout the summer season. Designed to meet the evolving needs of modern households, LG's French door models offer a sophisticated blend of capacity, efficiency, and smart capabilities, ensuring food stays fresher for longer when temperatures rise. Engineered with a focus on superior cooling and preservation features like DoorCooling+™, provides a consistent and even temperature throughout the refrigerator, including the door area, which is often susceptible to temperature fluctuations. This rapid cooling capability helps maintain the freshness of frequently accessed items. Technology that works in tandem is the LINEARCooling™ system, too, minimizes temperature variations, preserving the flavor and texture of fresh produce for extended periods; crucial during warmer weather when food spoilage can accelerate. Beyond core cooling, LG's French door lineup integrates smart features that enhance user experience. Smart Diagnosis™, for instance, allows for easy troubleshooting, providing peace of mind and efficient maintenance, while many models also incorporate UVnano™ technology in the water dispenser, which automatically cleans the nozzle with UV light, ensuring a hygienic water supply. Hygiene Fresh+™ technology, meanwhile, ensures optimal food freshness through advanced air purification. Customers can control all these features and more through the intuitive LG ThinQ™ app, putting them in complete command of their kitchen experience. LG's InstaView™ Door-in-Door® feature is not only fun and stylish, offering a convenient way to see inside the refrigerator without opening the main door, but functional too, as it reduces cold air loss and saving energy, a significant benefit during peak energy consumption periods. The standout latest addition to LG's French door portfolio, however, transcends traditional refrigeration. An innovative appliance, the MoodUP™ refrigerator affords owners greater personalization. With over 170,000 color combinations available for the vibrant LED door panels, the possibilities to transform the kitchen's ambiance to match mood, music, time of day, occasion, or even simply the season, are endless. Beyond its stunning visual appeal, the MoodUP™ Refrigerator boasts a suite of innovative features designed to enhance modern living, such as integrated Bluetooth speakers that impeccably synchronize with its owner's favorite music, and the vibrant panel lighting, creating the perfect atmosphere for social gatherings, delivering both style and substance. With a focus on reliability, efficiency, and user-centric innovation, LG's French door refrigerators, including the pioneering MoodUP™ model, are prepared to deliver unparalleled performance throughout the summer months.

This new biodegradable film could save 20 per cent on energy bills
A new biodegradable film developed by scientists in China and Australia could slash building energy use by up to 20 per cent and keep surfaces up to 9.2C cooler without using any electricity, according to a new study. The material is made from polylactic acid – a bioplastic derived from plants – and passively reflects nearly all solar radiation while allowing heat from inside buildings to escape into the sky. Researchers from Zhengzhou University and the University of South Australia say the metafilm can be an alternative to air conditioning systems, which contribute significantly to greenhouse gas emissions in cities. 'Our metafilm offers an environmentally friendly alternative to air-conditioning,' Yangzhe Hou, lead author of the study and a PhD candidate at the University of South Australia and Zhengzhou University. 'The material reflects nearly all solar radiation but also allows internal building heat to escape directly into outer space. This enables the building to stay cooler than the surrounding air, even under direct sunlight.' In testing, the film passively reduced temperatures by as much as 9.2C during peak sunlight hours, according to the study published in Cell Reports Physical Science on Wednesday. On an average, it kept surfaces 4.9C cooler during daytime and 5.1C cooler at night. Unlike conventional cooling systems, the film requires no electricity or mechanical components. The metafilm also withstood harsh weather conditions, maintaining its cooling performance even after 120 hours of exposure to strong acid and the equivalent of eight months of ultraviolet exposure outdoors, according to the study. It continued to cool surfaces by up to 6.5C under those conditions. 'Most existing passive radiative cooling systems rely on petrochemical-based polymers or ceramics that raise environmental concerns,' Dr Xianhu Liu from Zhengzhou University said. 'By using biodegradable PLA, we are presenting a green alternative that offers high solar reflectance, strong thermal emission, sustainability and durability.' Computer simulations showed using the metafilm on buildings in hot cities such as Lhasa in China 's Tibet region could reduce annual energy consumption by over 20 per cent. 'This isn't just a lab-scale success,' Professor Jun Ma from the University of South Australia claimed. 'Our film is scalable, durable and completely degradable. This research aims to contribute to sustainable development by reducing reliance on fossil fuels and exploring feasible pathways to improve human comfort while minimising environmental impact.' The team is now looking into large-scale manufacturing and possible applications in transportation, agriculture, electronics and biomedical products, including cooling wound dressings. Passive cooling technologies have gained traction in recent years, with various teams experimenting with ceramic coatings, reflective paints, and polymer-based films. However, many such innovations have faced limitations around cost, fragility, or environmental impact. Other recent breakthroughs include an ultrawhite starch-based film that passively cools surfaces by reflecting 96 per cent of sunlight and a ceramic roof coating that withstands extreme temperatures while reducing cooling loads by 20 per cent.
