Des chercheurs Américains et en Chinois viennent de faire de sérieux progrès vers la production relativement simple et peu coûteuse de «tissus intelligents», des textiles électroniques capables de détecter les maladies, surveiller le rythme cardiaque ainsi que d'autres signes vitaux.
Les résultats de cette recherche digne d’un roman de science-fiction publié dans le magazine scientifique ACS' Nano Letters de décembre. Dans cette étonnante étude, Nicholas A. Kotov de l’Université du Michigan et Chuanlai Xu de l’Université Jiangnan, soulignent que les textiles électroniques, ou «e-textiles», sont déjà une réalité. Periodic Table of Visualization Methods. Chemistry. What is the full chemical name for titin. Titin, also known as connectin, (UniProt name: Q10466_HUMAN; accession number: Q10466) is a protein that is important in the contraction of striated muscle tissues.
Titin connects the Z line to the M line in the sarcomere. The protein limits the range of motion of the sarcomere in tension, thus contributing to the passive stiffness of muscle. Chemistry. Alchimie Alchemy. Coloured alchemical emblems. Over the past ten years or so I have been making handcoloured emblems by painting with watercolours copies of woodcuts and engravings from printed books and some manuscript drawings.
In colouring these I made use of my intensive study of the original coloured manuscripts of the 15th to 18th centuries, which have been the main focus of my research over the past years. I have often found that by contemplating and meditating on these handcoloured images one can resonate with and enter into the complex symbolic world of alchemy. I regret that I can only supply these images as these small thumbnails on this internet web site. Earlier in 1999 I did place full page images on this site, but some people just took these without my permission and used them in their own web sites and in other projects.
One person in particular even claimed he had copyright over an image that I painted and is still hanging on my kitchen wall ! 297 individual emblems divided into a series of galleries.

Origin of the Periodic Table. I know what the periodic table looks like, but where did it come from?
Whose idea was it to arrange the elements this way? He set them out in order of atomic weight, and then grouped them into rows and columns based on their chemical and physical properties. 1869...that's way before the Schrödinger model, or even the Rutherford model. That's right. Mendeleev had no idea what atoms were made of or why they behaved as they did. Based on the gaps in his table, Mendeleev even succeeded in predicting the existence and properties of several new elements. That's pretty impressive. His basic rule was this: the elements in any column, or group, of the table are similar to their column-mates.
