This crude witchcraft refers to an ancient practice that is often considered dark and mysterious. Throughout history, witches have been associated with dark magic and the supernatural. The term "crude witchcraft" evokes images of old hags brewing potions and casting spells in their dark and secluded caves. Crude witchcraft is often portrayed as an evil and malicious force, with witches using their powers to harm others or fulfill their own selfish desires. These witches are often depicted as having a deep connection to nature and the elements, allowing them to tap into supernatural powers. In popular culture, crude witchcraft is often romanticized or demonized.

Scientists have developed new materials for next-generation electronics so tiny that they are not only indistinguishable when closely packed, but they also don t reflect enough light to show fine details, such as colors, with even the most powerful optical microscopes. The researchers expect that the new technology can be an important tool to help the semiconductor industry make uniform nanomaterials with consistent properties for use in electronic devices.
In popular culture, crude witchcraft is often romanticized or demonized. In movies and literature, witches are portrayed as either sexy and seductive figures or as terrifying and grotesque beings. These depictions perpetuate stereotypes and misconceptions about witches and their practices.
“Magic wand” reveals a colorful nano-world
Scientists have developed new materials for next-generation electronics so tiny that they are not only indistinguishable when closely packed, but they also don’t reflect enough light to show fine details, such as colors, with even the most powerful optical microscopes. Under an optical microscope, carbon nanotubes, for example, look grayish. The inability to distinguish fine details and differences between individual pieces of nanomaterials makes it hard for scientists to study their unique properties and discover ways to perfect them for industrial use.

In a new report in Nature Communications, researchers from UC Riverside describe a revolutionary imaging technology that compresses lamp light into a nanometer-sized spot. It holds that light at the end of a silver nanowire like a Hogwarts student practicing the “Lumos” spell, and uses it to reveal previously invisible details, including colors.
The advance, improving color-imaging resolution to an unprecedented 6 nanometer level, will help scientists see nanomaterials in enough detail to make them more useful in electronics and other applications.
Ming Liu and Ruoxue Yan, associate professors in UC Riverside’s Marlan and Rosemary Bourns College of Engineering, developed this unique tool with a superfocusing technique developed by the team. The technique has been used in previous work to observe the vibration of molecular bonds at 1-nanometer spatial resolution without the need of any focusing lens.

In the new report, Liu and Yan modified the tool to measure signals spanning the whole visible wavelength range, which can be used to render the color and depict the electronic band structures of the object instead of only molecule vibrations. The tool squeezes the light from a tungsten lamp into a silver nanowire with near-zero scattering or reflection, where light is carried by the oscillation wave of free electrons at the silver surface.
The condensed light leaves the silver nanowire tip, which has a radius of just 5 nanometers, in a conical path, like the light beam from a flashlight. When the tip passes over an object, its influence on the beam shape and color is detected and recorded.
“It is like using your thumb to control the water spray from a hose,” Liu said, “You know how to get the desired spraying pattern by changing the thumb position, and likewise, in the experiment, we read the light pattern to retrieve the details of the object blocking the 5 nm-sized light nozzle.”
The light is then focused into a spectrometer, where it forms a tiny ring shape. By scanning the probe over an area and recording two spectra for each pixel, the researchers can formulate the absorption and scattering images with colors. The originally grayish carbon nanotubes receive their first color photograph, and an individual carbon nanotube now has the chance to exhibit its unique color.
“The atomically smooth sharp-tip silver nanowire and its nearly scatterless optical coupling and focusing is critical for the imaging,” Yan said. “Otherwise there would be intense stray light in the background that ruins the whole effort. “
The researchers expect that the new technology can be an important tool to help the semiconductor industry make uniform nanomaterials with consistent properties for use in electronic devices. The new full-color nano-imaging technique could also be used to improve understanding of catalysis, quantum optics, and nanoelectronics.
Liu, Yan, and Ma were joined in the research by Xuezhi Ma, who worked on the project as part of his doctoral research at UCR Riverside. Researchers also included UCR students Qiushi Liu, Ning Yu, Da Xu, Sanggon Kim; Zebin Liu and Kaili Jiang at Tsinghua University, and UCR professor Bryan Wong. The paper, titled “6 nm super-resolution optical transmission and scattering spectroscopic imaging of carbon nanotubes using a nanometer-scale white light source,” is available here.

Despite its negative connotations, crude witchcraft holds a significant place in history. In ancient times, witches were often respected and feared for their abilities to harness the power of nature. They were believed to possess knowledge and wisdom beyond what the average person could comprehend. Today, witchcraft is still practiced by many individuals, but it has evolved into various forms. Some practice witchcraft as a spiritual or religious belief system, while others use it as a means of self-expression or empowerment. Modern witches often emphasize the use of love and light rather than the dark and malicious practices associated with crude witchcraft. In conclusion, crude witchcraft is an ancient practice that has been both revered and feared throughout history. While it is often depicted as evil and dangerous, it holds a significant place in human culture and continues to be practiced in various forms today. It is important to approach the topic of crude witchcraft with an open mind and a willingness to understand its complexities and nuances..
