The high cost of platinum is one of the main barriers to the wider adoption of hydrogen fuel cells. Now, researchers at IMDEA Materials Institute have developed a catalyst that delivers the same performance while using 75% less of this expensive metal. The study, published in Ele

Carbon dioxide is often viewed as a major contributor to climate change, but it can also become a valuable raw material. If scientists can efficiently convert carbon dioxide into useful fuels using sunlight, it would provide a sustainable way to store solar energy while reducing

Telegram is back on the App Store after Apple briefly removed it on Monday night over concerns about child sexual abuse material (CSAM). In a statement to Bloomberg's Mark Gurman, Apple says a review found that Telegram "violates our strict guidelines prohibiting child sexual abu

Material apreendido com a suspeita em Boa Vista Reprodução Uma mulher de 56 anos foi presa em flagrante por suspeita de tráfico de drogas na noite desse sábado (1º), no bairro Buritis, zona Oeste de Boa Vista. Segundo a Polícia Militar, com ela foram apreendidas 21 porções de cra

The heritage Japanese label is celebrating its 90th anniversary with the release of a commemorative book made of the same material as its famously strong bags.

A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials. By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to m

By rapidly twisting a microscopically small tip back and forth, researchers at the University of Maryland (UMD) have unlocked a new way to detect subtle changes on the surface of a material flexing in response to infrared light.

Entender as obras de Joan Miró (1893-1983) pode ser complexo. Muitas eram feitas de material incomum, como tampas de lata e pedaços de metal, com desenhos em formas estranhas e cores que representavam ou a guerra, ou a paz. Leia mais (08/06/2026 - 23h00)

Move to raise levy on goods made with polysilicon aims to protect domestic US supply chains from China, the major producerDonald Trump has ordered a new 15% tariff on imported products made of polysilicon, an important ingredient in microchip manufacturing that is primarily produ

TCC de Direito com frase 'Antes Elize do que Eliza' viraliza nas redes Talvez você tenha feito seu Trabalho de Conclusão de Curso (TCC) no fim da faculdade e sentido que quase ninguém, além da banca de professores, leu o material. Bom, definitivamente, não foi o que ocorreu com C

Existe um erro muito comum entre quem está começando a estudar para concursos públicos: acreditar que a aprovação depende apenas de inteligência, da qualidade do material ou da quantidade de horas estudadas. É claro que tudo isso importa. Mas existe um fator que está acima de tod

Researchers have found a way to build much larger “twisted” oxide materials while precisely controlling how their atomic layers line up. Because these materials can be made over large areas and transferred onto different surfaces, the technique could help turn twistronics from a
