Protein-splitting enzymes play an important role in many physiological processes. Such proteases are generally present in an inactive state, only becoming activated under certain conditions. Some are linked to diseases like infections or cancer, making it
阅读全文物质与能量研究人员通过在光纤上3D打印微光学来制造稳定的混合激光器
For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and stable laser sources that would be useful in a variety of
阅读全文物质与能量研究为电化学控制离子选择性提供了新途径
A new study by researchers at the University of Illinois Urbana-Champaign advances fundamental knowledge about the role of solvation in ion binding and presents a new pathway for electrochemically controlling ion selectivity. The study was published in
物质与能量这种自适应屋顶瓷砖可以降低供暖和制冷成本
About half of an average American building's energy consumption is spent on heating and cooling. That's a lot of money spent, fossil fuel burned and strain on an aging energy infrastructure during times of severe temperatures.

While screen time is generally known to affect sleep, new research suggests that interactive engagement, such as texting friends or playing video games, delays and reduces the time spent asleep to a greater extent than passive screen time, like watching t
阅读全文物质与能量研究人员找到了在不熔化泡沫的情况下焊接金属泡沫的方法
Researchers at North Carolina State University have now identified a welding technique that can be used to join composite metal foam (CMF) components together without impairing the properties that make CMF desirable. CMFs hold promise for a wide array of

With the holiday season in full swing, gifts of all shapes and sizes are being shipped around the world. But all that packaging generates lots of waste, including cardboard boxes and plastic-based foam cushioning, such as Styrofoam™. Rather than dis
阅读全文物质与能量下一代蓝光可能会促进或阻碍睡眠
Blue light from LED lamps and consumer electronics can mess with your sleep because it disrupts production of the natural sleep hormone melatonin. Tinted glasses or displays in night mode can mask, but don't remove, a portion of the disruptive wavelength
阅读全文物质与能量一对很有希望的搭档：科学家为量子科学展示了新的材料组合
Quantum information scientists are always on the hunt for winning combinations of materials, materials that can be manipulated at the molecular level to reliably store and transmit information.
