When most people think about milk, they picture breakfast cereal or a cappuccino. But beneath its creamy surface lies a complex colloidal system — and one of its star players is casein, a protein family with remarkable structural and functional properties. From nanoparticle engineering to biodegradable plastics, casein has been quietly shaping both our food and materials industries for over a century.
(more…)Synthetic rubies have fascinated scientists and jewelers alike for over a century. While natural rubies form deep within the Earth under immense heat and pressure, synthetic methods allow for the controlled creation of rubies with specific properties and flawless clarity. One of the most historically important and widely used techniques for producing synthetic rubies is flame fusion, also known as the Verneuil process.
Last week, we covered solar and thermoelectric energy generation. This week, we’ll cover geothermal and hydroelectric power.
As climate change accelerates and fossil fuels continue to pollute our atmosphere, the world is racing toward cleaner, more sustainable energy solutions. But what often goes unnoticed behind the scenes are the materials— the alloys, nanotechnology, polymers, and crystals that make renewable energy possible. Over the next two weeks, we’ll compare four powerful energy solutions: solar, thermoelectric, geothermal, and hydroelectric; and explore how materials science drives innovation in each. Today, we will discuss solar and thermoelectric energy generation.
