In a method of making a carbon fiber, PAN (poly(acrylonitrile-co methacrylic acid)) is dissolved into a solvent to form a PAN solution. The PAN solution is extruded through a spinneret, thereby generating at least one precursor fiber. The precursor fiber is passed through a cold gelation medium, thereby causing the precursor fiber to gel. The precursor fiber is drawn to a predetermined draw ratio. The precursor fiber is continuously stabilized to form a stabilized fiber. The stabilized fiber is continuously carbonized thereby generating the carbon fiber. The carbon fiber is wound onto a spool. A carbon fiber has a fiber tensile strength in a range of 5.5 GPa to 5.83 GPa. The carbon fiber has a fiber tensile modulus in a range of 350 GPa to 375 GPa. The carbon fiber also has an effective diameter in a range of 5.1 μm to 5.2 μm.

A system and method for real-life interactive experience between virtual participants in a gathering of up to thousands of people attending a streamed event, using their computers and mobile devices. The virtual participants sit at boxes and tables at the event and see video and hear audio of other participants sitting at the same table and box. The participants interact with other participants of their choosing without disturbing the rest of the participants. They can use local chat boxes and global chat boxes to chat with the participants of the event. The participants may virtually move from one area to another area of the event using the event layout and sit in a new area of their choosing as they would at an in-person event while watching the streaming of the event thus providing a close to real-life experience of interacting with the event participants.

In a method of making a high surface area carbon material, a precursor organic material is prepared. The precursor organic material is subjected to a first elevated temperature while applying a gaseous purge thereto for a first predetermined time. The precursor organic material is subjected to a second elevated temperature while not applying the gaseous purge thereto for a second predetermined time after the first predetermined time. A high surface area carbon material includes carbon and has a surface area in a range between 3029 m/g to 3565 m/g and a pore volume in a range between 1.66 cm/g and 1.90 cm/g. The high surface area carbon material may be employed in an electrode for a supercapacitor.

Disclosed herein are method, system and computer-readable storage media for gift card e-banking. This is a unique platform, where people can deposit and withdraw gift cards of any store, of any denomination, at any time and at any place from the bank. Gift cards are converted into virtual money not affiliated with any store. Unlike traditional banking system majority of transactions are in the form of gift cards. Customers have two types of accounts, gift card money account and fixed account. The gift cards deposited in the bank account are available to all the customers. Cards deposited in the fixed account are only available to the customer who owns that account. Customer may transfer gift card/virtual money from one account to another account. Gift card e-bank also issues its own gift card known as 'one gift card', which facilitates customers to use any gift card at any store.
