Photobiocidal Activity of TiO/UHMWPE Composite Activated by Reduced Graphene Oxide under White Light.

Herein, we introduce a photobiocidal surface activated by white light. The photobiocidal surface was produced through thermocompressing a mixture of titanium dioxide (TiO), ultra-high-molecular-weight polyethylene (UHMWPE), and reduced graphene oxide (rGO) powders. A photobiocidal activity was not observed on UHMWPE-TiO.

Tris(β-ketoiminate) Aluminium(III) Compounds as Aluminium Oxide Precursors.

Precursor design is the crucial step in tailoring the deposition profile towards a multitude of functional materials. Most commercially available aluminium oxide precursors require high processing temperatures (>500 °C). Herein, we report the tuning of the decomposition profile (200-350 °C) of a range of octahedrally coordinated tris(β-ketoiminate) aluminium complexes of the type [Al(MeCN(R)CHC=OMe) ], by varying the R substituents in the ligands.

Overcoming the unprecedented: Micro, small and medium hospitality enterprises under COVID-19.

The sudden irruption of COVID-19 has paralysed, even devastated, numerous industries. Academic and industry publications also convey the destructive impacts of this phenomenon on hospitality and tourism businesses. While business owners and managers are still constrained by unpredictability, restrictions, and ongoing uncertainty, those vying to continue will need to build their adaptive skill repertoire to cope with the crisis-related regime.

COVID-19, aftermath, impacts, and hospitality firms: An international perspective.

Drawing on the theory of resilience, and on an international sample of 45 predominantly small hospitality businesses, this exploratory study extends knowledge about the key concerns, ways of coping, and the changes and adjustments undertaken by these firms' owners and managers during the COVID-19 outbreak. The various emergent relationships between the findings and the considered conceptual underpinnings of the literature on resilience, revealed nine theoretical dimensions. These dimensions critically illuminate and extend understanding concerning the actions and alternatives owners-managers resorted to when confronted with an extreme context.
