Abstract: A self-healable hydrogel of acrylic acid (AA) graft copolymerized with gum Arabic (GA) via ferric ions cross-linking. The GA is imparted as a cluster molecule that offers a diffusionless solvent independent non-bonding interaction in the hydrogel and mediate strong bonding interactions. Methods of fabricating the hydrogel and a triboelectric nanogenerator (TENG) are also described. Besides self-healing characteristics, the TENG device retains high output performance of ambient state, at aqueous and frozen states owing to availability of electrostatically triggered diffusionless interaction in all states.

Abstract: A non-combustible aerosol provision system includes an article comprising a rod of aerosol generating material having a circumference greater than 19 mm and a non-combustible aerosol provision device for heating the aerosol generating material of the article, the non-combustible aerosol provision device comprising a coil.

Abstract: A carbon emissions manager receives surface drilling parameters for drilling equipment at a downhole drilling operation. Using the surface drilling parameters, the carbon emissions manager determines a power draw from a generator by the drilling equipment. The power draw is related to the diesel fuel consumed by the generator. Using the diesel fuel consumption, the carbon emissions manager determines carbon emissions for the drilling equipment.

Abstract: An article for use in a non-combustible aerosol provision system that includes an aerosol provision device. The article includes a rod of aerosol-generating material having a distal end for insertion into the non-combustible aerosol provision device such that a heating element of the device extends into the rod of aerosol-generating material through said distal end. The article includes a cavity extending in a longitudinal direction into the rod of aerosol-generating material from said distal end to receive the heating element. A system including a non-combustible aerosol provision device having a heating element, and an article according to the invention, together with a method of manufacturing an article according to the invention is also disclosed.
