Las tablas periódicas más frikis. Chemistry. Canoë - Techno-Sciences - Des vêtements intelligents pour détecter les maladies. 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. Toutefois, ceux qui existent actuellement sont volumineux, rigides et complexes si bien qu’ils ne sont pas du tout pratiques. Les fabricants de textiles ont besoin de matériaux à la fois simples et souples pour être en mesure de fabriquer des fibres intelligentes utilisables pour des applications futures.

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. Variations in the sequence of titin between different types of muscle (e.g. cardiac or skeletal) has been correlated with differences in the mechanical properties of the muscles.[1] Titin is the largest known protein, consisting of 26,926 amino acids. The molecular weight of the mature protein is approximately 2,993,451.39 Da, and it has a theoretical pI of 6.35 [1]. As the largest known protein, titin has the longest full chemical name. Titin (UniProt name: Q10466_HUMAN; accession number: Q10466) is a protein that is important in the contraction of striated muscle tissues.

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.
