Abstract: A contactless delivery locker may have a locker housing with a locker door fitted to the locker housing. A disinfecting system may be arranged to disinfect the locker content and a remotely actuable lock may be arranged to secure the locker door in a closed position and actuable to release the locker door. A controller associated with the lock may be configured to actuate the lock and a wireless interface may be connected to the controller and configured to receive a command to actuate the lock to release the locker door. The controller may operate to control actuation of the lock to release the locker door upon detection of a command to actuate the lock and release the locker door. The controller may be configured to report lock status information to a user to confirm if a locker has been opened after completion of a disinfecting cycle.

Abstract: A method of imparting color to a plastic substrate comprising applying to the substrate, or incorporating within the substrate, a diacetylene compound of general formula (I) wherein n=1 to 20; R1=an optionally substituted C1-20 alkyl group which may contain heteroatoms; T=H, an optionally substituted C1-20 alkyl group which may contain heteroatoms or —(CH2)m—C(?O)-Q2R2; Q1=NH, CO, NHCONH, OCONH, COS, NHCSNH or NR3, wherein m, Q2 and R2 are independently selected from the same groups as n, Q1 and R1 respectively; R3 is an optionally substituted C1-20 alkyl group which may contain heteroatoms; and irradiating the substrate to impart color to the substrate is described.

Abstract: Ink formulations and methods of using the same in laser-imaging are provided. An ink formulation can comprise a graphene-based component, a colour change agent, a binder, and a solvent. Substrates, coatings, and articles comprising a graphene-based component are also provided, and laser marking can be brought about by an ablation or direct charring process.

Abstract: Water soluble marking compounds comprising a transition metal oxyanion and at least one ammonium cation, comprising a nitrogen atom at least one further group selected from the group consisting of OH, COOH, NH2, NHC1-5 alkyl, and N(C1-5 alkyl)2, wherein the two C1-5 alkyl may be the same type of alkyl or different alkyls, may be used to obtain clear imageable coatings.

Abstract: The disclosed invention relates to the use of molybdenum (VI) peroxo complex containing an amino acid, such as MoO(O2)2(GLY)(H2O), in marking applications, as well as to ink formulations comprising such complexes.

Abstract: A method of forming a coloured substrate, comprising applying to or incorporating within the substrate a diacetylene compound, and exposing the substrate to (i) a first, activating stimulus that converts the diacetylene compound from an unreactive to a reactive form, and (ii) a second stimulus that causes the reactive form of the diacetylene compound to polymerize and form the coloured substrate, wherein the diacetylene compound reverts to its unreactive form on removal of the activating stimulus and is of formula I: Y—C?C—C?C—(CH2)n-T-Q-Z (I) wherein: n=an odd integer; T=CO, CS or a bond; Q=NH, S, O, OCONH, NHCONH, NH—CHE-CONH, NHCOO or NHCSNH wherein E is H or a C1-20 alkyl group; Z=H or a hydrocarbon group containing 1 to 20 carbon atoms; Y=H or any group comprising at least one carbon atom.
