大多数冰箱贴虽单个重量不大，但如果是大面积整块磁贴、金属材质或立体装饰款，长期集中贴在某一区域，就会形成持续的局部压力。外层金属面板在长期施压下，可能出现细微的形变；中间的发泡层虽有一定弹性，但长期受力会逐渐失去回弹能力，进而影响门体的平整度 [4] ...

A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...

Researchers analyzed 28 Ryugu asteroid samples and found preserved magnetic signals that record early solar system magnetic ...

Innovative materials could help to reduce the energy consumption of electrical devices, allowing drones to fly longer and e-bikes to travel further. By introducing components made from metallic glass ...

Researchers in Europe are developing metallic glass materials that could significantly reduce energy losses ...

市面上99%的冰箱贴都离不开“软磁材料”这一核心原料。软磁材料是一类在弱磁场下就能被磁化，去掉磁场后磁性又能快速消失的材料，常见的有 铁氧体软磁（磁性氧化物+陶瓷材料）、橡胶磁（软磁材料+弹性基材）等。它的最大优势是磁性温和且可塑性强，能 ...

Scientists studying tiny samples from the asteroid Ryugu have uncovered new clues about the magnetic environment that existed ...

A newly mapped form of superconductivity in uranium ditelluride emerges only under extremely strong magnetic fields, defying long-held expectations about how superconductors behave.

Scientists discover that the Earth's magnetic poles can take up to 70,000 years to reverse, much longer than previously ...

Depression-related fatigue is caused by cellular "overworking" at rest and a failure to produce energy under stress.

The new capsule robots developed for medical applications can reportedly be swallowed by patients and steered using magnetic fields. The team explained that such robots could reduce the current ...

Scientists studying lunar samples have finally resolved a decades-long debate about the Moon’s ancient magnetic field.
