Geologists in China have unearthed a new type of ore that’s rich in niobium, a much-prized metal with superconductive properties

Geologists in China have unearthed a new type of ore that’s rich in niobium, a much-prized metal with superconductive properties that is used in everything from steel production to jet engines and particle accelerators.  Dubbed niobobaotite, the ore was recently discovered within the Bayan Obo Mining District of Inner Mongolia in China, according to an announcement from the China National Nuclear Corporation (CNNC). They explained that the ore is rich in barium, titanium, iron, chlorine, and – most excitingly – niobium. 


Uses


Niobium is a type II superconductor, which means that it can carry very high currents and withstand strong magnetic fields without losing its superconductivity. This makes it ideal for a wide range of applications, including:


Superconducting magnets: Niobium is used to make superconducting magnets for a variety of applications, including MRI machines, particle accelerators, and nuclear fusion reactors. Superconducting magnets are much more powerful and efficient than traditional electromagnets, and they are essential for many cutting-edge technologies.


Superconducting power transmission lines: Niobium could be used to make superconducting power transmission lines, which would be able to carry much more electricity than traditional copper lines with much less loss. This would make it possible to transmit electricity over long distances more efficiently and economically.


Superconducting devices: Niobium is also used to make a variety of superconducting devices, such as superconducting SQUIDs (superconducting quantum interference devices), which are used to measure extremely small magnetic fields, and superconducting qubits, which are used in quantum computers.


Niobium is a relatively rare metal, but the discovery of niobobaotite ore in China could make it more widely available and affordable. This would boost the development of superconducting technologies and could lead to new and innovative applications.


Here are some specific examples of how niobium is used in superconductivity:


The Large Hadron Collider (LHC), the world's largest and most powerful particle accelerator, uses superconducting magnets made of niobium-titanium alloy.


The ITER nuclear fusion reactor, which is currently under construction in France, will use superconducting magnets made of niobium-tin alloy.


MRI machines use superconducting magnets to generate the powerful magnetic fields needed to create detailed images of the inside of the body.


Superconducting SQUIDs are used to detect magnetic fields from the brain, heart, and other organs for medical research and diagnostics.


Superconducting qubits are being used to develop quantum computers, which have the potential to solve problems that are intractable for classical computers.


The discovery of niobobaotite ore in China is a significant development for the field of superconductivity. Niobium is a key material for many superconducting technologies, and the increased availability and affordability of niobium could lead to advances in a wide range of fields, including medicine, physics, and engineering.

chemo

  The chemo cocktail churns, a metallic serpent coiling in my gut, its venom rising, a bitter tide. The sterile air, a canvas for the symphony of beeps, a haunting counterpoint to the hollowness inside. My reflection mocks from the steel embrace of the chair, a gaunt caricature, eyes hollowed, skin the hue of despair. Each breath a labored rasp, a dry leaf skittering on stone, as the serpent writhes, promising oblivion's unknown. Sleep, a fragile escape, crumbles into a twisted dream. A figure cloaked in midnight strides across the barren plains, his scythe a crescent moon, casting an inky sheen on the cracked and thirsty earth, mirroring my ravaged veins. The Grim Reaper, eyes smoldering embers in the gloom, a silent judge, his gaze a pronouncement of impending doom. His skeletal hand reaches, cold and sure, to claim my soul, but a spark of defiance flares, a flicker to regain control. I lunge, a frail wisp against the night's cold embrace, but the figure fades, leaving on...

My wife was only 32 when she died of metastatic breast cancer

Image
It was only 5 years after we found a lump in her breast.  She was a laboratory technologist in the hospital lab at the time and our medical insurance was good.  To give her the best chance, they gave her both chemotherapy and radiation to the area where the tumor had been found after surgery.  Our son was 1 1/2 years old at the time of the diagnosis and spent a lot of time at his grandmother's house during her treatments.  I went with her each time she received chemo and went through her nausea and vomiting with her after each course. In time they tattooed a tiny dot on her breast in order to guide the radiation to the right area and completed the radiation treatments.  She began recovering and within months had returned to her job at the lab. We both raised our son and went about our lives, hopeful. They did tests for tumor markers monthly without apparent return of the cancer.  One day, 5 years from the beginning she felt bad and was hospitalized. The tum...

Magic Carpet Ride

Image
 Let me take you on a magic carpet ride No silken carpet, stitched by hands unknown, But woven moonlight on a phoenix's down. With whispers of magic, we'll ascend the sky, Where stars like diamonds dance and planets sigh. Through emerald valleys, where dragons sleep, And crystal rivers secrets keep. On winds of laughter, past castles untold, With stories blooming, braver than gold. We'll chase shooting stars across the night, Their fiery whispers our guiding light. Past hidden waterfalls, where sirens sing, And wishes take flight on gossamer wing. No jeweled palace, but a moonlit bower, Where fireflies light each fragrant flower. With hearts entwined, beneath the Milky Way, We'll write our own love story, come what may. This magic we create, unseen, unheard, A tapestry woven with every shared word. So let us dance on stardust, wild and free, For the truest magic lies in you and me. With brushes dipped in dreams, we'll paint the sky, Our souls entwined, as colors dan...
