阅读全文Structural design and characterization of sa-SWNTs In order to achieve the uniform dispersion, optimal alignment and strong interaction of SWNTs in HAFs, we report a four-step method to prepare sa-SWN...
阅读全文By first using a laser to strip an electron from the neutral methane molecule, then taking ultrafast x-ray spectroscopic snapshots of the remaining ion, the researchers collected a time series of spec...
阅读全文Nanoparticles do the same thing. Previously, Glotzer’s team had shown that bipyramid particles—like two short, three-sided pyramids stuck together at their bases—will form structures resembling tha...
阅读全文When nanomaterials are exposed to external environments such as electric potentials or pH, their surfaces exhibit various phases because the dominant adsorbate species may change1,2,3,4. The surface p...
阅读全文The remarkable feature of the proposed device is its ability to change its functionality simply by replacing the meta-optics linked to the PIC. This allows for a wide range of possibilities for contro...
阅读全文“Our novel artificial muscle fiber also exhibits unprecedented reversible percolation of graphene filler network under stable actuation along the alignment direction, resulting in in-situ monitoring ...
阅读全文锂电太阳能路灯的发电能量是太阳能电池板,是LED路灯的重要组成部分之一。LED路灯是一种基于半导体pn结发光的效率较高的固态光源。在一定的正向偏压和注入电流下,注入P区的空穴和注入n区的电子扩散到有源区,通...
阅读全文‘We added a heater to the bolometer, so we can apply a known heater current and measure the voltage. Since we know the precise amount of power we’re putting into the heater, we can calibrate the pow...
阅读全文In recent years, super-resolution techniques have made leaps and bounds to resolve many sub-cellular structures below the classical diffraction limit of light. Single molecule localization microscopy,...
阅读全文A critical aspect of managing magnetic skyrmion movement lies in controlling magnetic anisotropy, which influences the energy of skyrmions. Previous research endeavored to regulate magnetic anisotropy...
阅读全文奧地利維也納工業大學(TU Wien)成功地開發了一項利用陶瓷材料的氧離子電池。氧離子電池的能量密度不如鋰離子電池高,但蓄電量不會隨時間減少,因此可望有較長的使用壽命。此外,由於材料中不使用稀有元素,而是採用不...
