Detail photo of the positioning of a small glass tube filled with argon gas that contains a twisted nanocarbon across from a high-resolution micro lens, which will be used to monitor the local temperature of the small filaments in an experiment in the Kotov Lab at the North Campus Research Center of the University of Michigan in Ann Arbor on Wednesday, December 18, 2024. This lens and the software used with it allowed for precise thermal mapping of the twisted nanocarbon. The glass tube is filled with argon because nanocarbon is highly susceptible to oxidation under air conditions, especially when heated. Argon, being an inert gas, prevents oxidation and ensures the stability of the nanocarbon during high-temperature operation.
Researchers from the Kotov Lab have found that submicrometer twisted filaments made from materials like nanocarbon or metals can produce strong chiral infrared photons, especially in the wavelength range of 500 to 300 nanometers. The twisted filaments emit light that is significantly brighter, up to 100 times more bright than other similar light emitters. The special helical shape of the filaments helps in controlling the type of twisted light they emit. Additionally, coating these nanocarbons with durable, transparent ceramics results in bright and adjustable chiral emitters capable of functioning at temperatures that were previously thought to be unreachable. This advancement opens new possibilities in the field of chiral photonics and high-temperature applications. COMPASS is the Center for Complex Particle Systems which is directed by Nicholas Kotov, the Irving Langmuir Distinguished University Professor of Chemical Sciences and Engineering.

Tung trees were mainly planted at places where Hakka people live and are a significant symbol of Taiwan Hakka culture. Tung Trees are deciduous trees that can grow up to about 20 meters tall, can be commonly found in southern China, Burma, and mostly northwestern Taiwan. Large numbers of Tung Trees were planted during the Japanese colonization period in the hills of Miaoli as the location has the ideal condition for its growth. In the past, most of the Hakka people made living by extracting oil from Tung Tree seeds, flowers as food ingredients, and wood as raw materials. Today, Tung trees are no longer the major crop of Hakka as there are cheaper alternatives, but Hakka people still cherish for the good things that Tung trees have given them in the past.
There are two species of Tung Trees in Taiwan include aluerites fordii hemsj that blooms around April to July and aleurites Montana that blooms a bit earlier, from March to May. Tung Blossoms are favored for their appearance of pristine white petals and red filaments with yellow anthers. When it comes to the Tung blossom festival, these beautiful Tung blossoms cover the country roads and hills in large numbers and size, providing mesmerizing sceneries just like a layer of snow.
The Jacaranda flowers are falling to the ground, this is a very close up macro of the filaments inside the flower, note the ones that have fallen onto the petal. These flowers are usually filled with bees so one has to be very careful how you walk around when the jacaranda blooms are lying on the ground!
El diseño de la bombilla LED de filamento es muy parecida a la bombilla tradicional de filamento de carbón. Sin embargo, la bombilla LED tiene muchas ventajas, tiene una alta representación del color, asegura un ahorro de energía del 85-92%, tiene una vida útil de 15000 horas y un tiempo de reembolso de solo 4-8 meses. normasym.com/es/productos/reequipamiento/bombilla-led-de-...
