Abstract: The present invention is a blockchain-driven ecosystem that aims to make nurses' lives easier by providing them with the best employment opportunities, benefits, and services. This helps nurses by reducing stress and burnout while providing benefits such as insurance, retirement advice, and education. The ecosystem is comprised of participants which include clinicians, facilities, vendors, recruiters, service providers, contributors, and franchisees. A rewards system is triggered by the actions of the different participants. Rewards can be used to purchase services from service providers in a rewards redemption application. Each participant can earn and spend rewards in the ecosystem. Rewards can be converted into stablecoins to withdraw them to a bank account. The platform is built on the Ethereum Virtual Machine with blockchain bridging capacity. It uses smart contracts to execute payouts, take and record votes, record rewards earned, and store medical credentials.

Abstract: A cartridge comprising a cartridge body and a capture medium holder disposed within the body, the capture medium holder comprising a platform configured to receive a capture medium, the capture medium holder being configured to move relative to the cartridge body between a sample collection position in which the platform is aligned with a sample inlet of the cartridge body and an inspection position in which the platform is aligned with an inspection window of the cartridge body.

Abstract: A polymer comprising a first repeat unit of formula (I), wherein each Ar is independently selected from optionally substituted aryl or heteroaryl and the group of formula (I) is present in a molar ratio of less than or equal to 10%, and, optionally, a second, optionally substituted repeat unit having a single nitrogen atom in its backbone of formula —Ar—N(Ar)—Ar— in a molar ratio of no greater than 5%.

Abstract: An optical device comprising an anode, a cathode comprising barium, strontium or calcium, and a layer of organic semiconducting material between the anode and the cathode wherein a layer of hole transporting and electron blocking material is located between the anode and the layer of organic semiconducting material.
