L’amidon est mélangé avec de la nano-silice, le mélange obtenu est traité thermiquement à une température allant de 150°C à 240°C sous une atmosphère inerte, le premier produit fritté obtenu est traité thermiquement à une température allant de 180°C à 220°C sous une atmosphère contenant de l’oxygène, le deuxième produit fritté est séparé de manière cyclonique pour éliminer la nano-silice afin d’obtenir des microsphères préoxydées à base d’amidon, et les microsphères préoxydées à base d’amidon subissent un traitement de carbonisation sous une atmosphère inerte pour obtenir le matériau d’anode en carbone dur. Dans la présente invention, les particules de silice peuvent être adsorbées sur la surface de la matière première d’amidon, et la réticulation se produit entre les chaînes moléculaires d’amidon au cours du processus de traitement thermique, et sous la barrière du dioxyde de silicium, les particules d’amidon ne seront pas réticulées mais fusionnées pour former une structure sphérique. L’introduction d’atomes d’oxygène au cours du processus de préoxydation produit une lacune d’oxygène et augmente les sites actifs pour le stockage d’ions sodium après la carbonisation, augmentant ainsi la capacité réversible des batteries au sodium-ion.

Title: Measurement of small amplitude displacements - diffraction of light beam caused by smegmatic liquid crystals
IPC: G02F1/13
Filed: 1973-05-15
Abstract: By using properties of smegmatic liquid crystals the measurement of small amplitude displacements exceeding a threshold of 100 angstroms is possible with a wide and flexible range of applications. A film of smegmatic A liquid crystals (10) is placed between two glass blades (11, 12) having parallel faces. Since the glass blades have some surface irregularities the working zone will have a measurement in plan of the order of 100 microns or less. The lower glass blade (12) is fixed in a box (13) with a window in the base. Monochromatic light (14) emitted by a laser source (15) strikes the crystals at the bragg angle. A screen (16) beneath the window displays the diffraction marks (17) from which displacement of the upper glass blade is obtained.

Abstract: The electric calling signal contains a number of a.c. signal sections alternating with d.c. signal sections. A circuit is provided responding to the a.c. and/or d.c. signal sections. A sound generator is connected to it, which generates a melodious acoustic signal when the calling signal is present. Means are provided responding to each a.c. signal section, and remaining operative until the next a.c. section arrives. A sound generator delivers a signal when the calling signal is present. An electromagnetic relay replaces the ringer in telephone instruments, with several normally open contacts closed when the relay is energised by an a.c. signal section. They remain closed until the next a.c. signal section arrives. When the contacts are closed, the sound generator emits a pleasant signal.
