Abstract: There is provided a bracket for a biological sample analyser. The bracket comprises abase and an arm extending from the base, the base being engageable with a platform of a biological sample analyser, wherein, when the base is engaged with the platform, the arm extends into a sample plate bay of the biological sample analyser prohibiting access to a portion of the bay. The arm thereby limits misalignment of a sample plate in the bay by blocking access to a portion of the bay only required when the sample plate is loaded into the bay in an incorrect orientation. A biological sample analyser comprising a bay in which a sample plate is loadable in use and the bracket is also provided.

Abstract: Coumarin modification of epoxies provide for epoxy adhesives that fluoresce under short wave ultraviolet irradiation while remaining invisible under normal light. Furthermore, these modified epoxy adhesives can have increased adhesive bond strengths. In addition, photochemical curing of an epoxy modified coumarin and a hardening agent with UV irradiation at certain wavelengths affords an epoxy adhesive composition. Further UV irradiation of the composition at certain wavelengths causes photoscission, which breaks the crosslinks that make the cured epoxy adhesive insoluble and intractable.

Abstract: Thermally reworkable epoxy resins prepared through a Diels-Alder reaction are described herein. A maleimide component is reacted with an electron donating component having a furan ring attached to an epoxy ether to produce the epoxy resins. The epoxy component generated by this method can be cured with different diamines lo form a robust network of epoxy material. The robust epoxy material is used as a reversible thermoset and as an adhesive. The robust epoxy network is heated at 90° C. temperature in a retro Diels-Alder fashion to produce colorless starting materials of the maleimide component and the furan component.

Abstract: UV absorbing monomers having one or more alkoxysilyl functional groups are produced through epoxide reaction chemistry. Sol-gel or emulsion polymerization of said UV absorbing monomers by themselves, or with alkoxysilane comonomers, affords nanoparticle sunscreens with reduced chemical exposure and improved photostability. Minimized leaching and decreased levels of photo-degradation were achieved with covalent incorporation to ensure isolation of the sunscreen chromophores and any photo-products from the skin.
