Abstract: The low-symmetry mesoporous titanium dioxide (lsm-TiO2) for use in an electrode for direct sensing of hydroxide ions may be prepared by evaporation-induced self-assembly followed by two stages of annealing. An electrode made of a conductive substrate coated with the lsm-TiO2 detects electrochemical oxidation of hydroxide ion solution by an oxidation peak for hydroxide ions at a lower potential than other metal electrodes. The oxidation process is irreversible under diffusion-control, the peak current linearly increases with hydroxide concentration within the concentration range from 1.0 to 50 mM, the detection limit may be 0.05 mM and the current sensitivity may be 0.181 mA/mM. The peak current is linearly dependent on alkaline solution pH and the dissociation constant of the hydroxide ion precursor. The electrode can be used in hydroxide sensing performed in nitrate, fluoride, chloride or sulfate supporting electrolyte, which makes the electrode a superior sensor for voltammetric hydroxide determination.

Abstract: Methods and systems of user authentication for roaming access to a wireless communications network, using blockchain, is described. A wireless access point (WAP) can provide roaming connectivity to a Wi-Fi network for a mobile device, for example at a public hotspot. The disclosed WAP is blockchain-enabled, allowing connectivity to a blockchain network. Accordingly, when a WAP receives a connection request to the Wi-Fi network, the WAP can execute a smart contract in the blockchain to determine whether a user of the mobile device is authenticated for roaming access to the Wi-Fi network. In some cases, the smart contract verifies that service providers of the mobile device and the Wi-Fi network have a roaming agreement. Also, the smart contact can verify that the user is authenticated by the service provider of the mobile device. In some cases, the WAP device functions in accordance with a Hotspot 2.0 (HS2) networking standard.
