An anode active material for a secondary battery according to an embodiment of the present invention includes a carbon-based particle containing pores, a silicon-containing coating layer formed at an inside of the pores or on a surface of the carbon-based particle, and a carbon coating formed on the silicon-containing coating layer. A ratio of a peak intensity (I.sub.D) of a D band relative to a peak intensity (I.sub.G) of a G band in a Raman spectrum of the carbon coating is 1.65 or less.

A metal nuclide-loaded carbon microsphere (CMS), and a preparation method and a use thereof are provided. The preparation method includes: subjecting a metal ion and a small organic molecule to a reaction in an aqueous solution to obtain a complex; allowing a CMS to adsorb the complex; and subjecting the CMS adsorbing the complex to a first treatment. The metal nuclide-loaded CMS prepared by the method can stably exist in an aqueous solution at a temperature of lower than 180° C. and a pressure of lower than 10 MPa and has a metal nuclide dissolution rate of lower than 0.1% in the aqueous solution. After the prepared metal nuclide-loaded CMS is subjected to moist-heat sterilization at 121° C. for 15 min, a radionuclide release rate is still lower than 0.1%, which can significantly reduce the safety risk of the radioactive microsphere product in clinical use.

Disclosed is a method of capturing an image of a scene using a user device having a rolling shutter camera. The scene is subjected to an illumination by an LED light source. The method includes providing, by the user device, a notification signal to the LED light source, the notification signal being indicative of a capturing or imminent capturing of an image; adjusting, by the LED light source, an operating characteristic of the LED light source, based on the notification signal; and capturing, by the rolling shutter camera, the image of the scene, while the LED light source is operating at the adjusted operating characteristic.

A filter apparatus for removing small molecule chemotherapy agents from blood is provided. The filter apparatus comprises a housing with an extraction media comprised of polymer coated carbon cores. Also provided are methods of treating a subject with cancer of an organ or region comprising administering a chemotherapeutic agent to the organ or region, collecting blood laded with chemotherapeutic agent from the isolated organ, filtering the blood laden with chemotherapeutic agent to reduce the chemotherapeutic agent in the blood and returning the blood to the subject.
