Formation of lanthanide luminescent di-metallic helicates in solution using a bis-tridentate (1,2,3-triazol-4-yl)-picolinamide (tzpa) ligand.

The chiral bis-tridentate (1,2,3-triazol-4-yl)-picolinamide (tzpa) ligand 1 was used in the formation of lanthanide di- and triple stranded di-metallic helicates in acetonitrile solution, where the changes in the ground and the Tb(III) excited state properties were used to monitor the formation of these supramolecular structures under kinetic control.

Generating water/MeOH-soluble and luminescent polymers by grafting 2,6-bis(1,2,3-triazol-4-yl)pyridine (btp) ligands onto a poly(ethylene--maleic anhydride) polymer and cross-linking with terbium(III).

The synthesis of two new polymers made from P(E-alt-MA) (poly(ethylene--maleic anhydride) and possessing 2,6-bis(1,2,3-triazol-4-yl)pyridine (btp) ligand side chains in 3 and 6 mol%, respectively (P1 and P2, respectively) is described. These polymers were shown to be soluble in MeOH solution and, in the case of P1, also in water, while P2 needed prolonged heating to enable water dissolution. Btp ligands are known for coordinating both d- and f-metal ions and so, herein, we demonstrate by using both UV-Vis absorption, fluorescence emission, as well as time-gated phosphorescence spectroscopies, that both P1 and P2 can bind to Tb(III) ions to give rise to luminescent polymers.

Digital training in the wake of a pandemic: Using technology to train health care professionals in the identification of human trafficking victims.

Human trafficking training is crucial for victim identification and appropriate service provision in health care settings. Over the past decade, the health care profession has made significant strides in the education and training of health professionals. However, access to quality training is still varied, and a unified education program has not been established.

Balancing connectivity with function in silver(i) networks of pyridyltriazole (tzpa) ligands results in the formation of a metallogel.

A new flexible and divergent 1,2,3-triazol-4-yl-picolinamide (tzpa) ligand 2 and the half-equivalent model ligand 1, both functionalised with pendant 3-pyridyl groups, are reported and their coordination behaviour with silver(i) ions is explored, both in the crystalline phase and through the formation of a supramolecular metallogel. The self-assembly of tzpa ligand 1 with AgCF3SO3 resulted in the formation of a 1D coordination polymer, binding in a bidentate fashion through the pyridyl and triazole nitrogen atoms of the tzpa binding site and a pendant pyridyl nitrogen atom of an adjacent ligand. Doubling the number of metal binding sites in ligand 2, while retaining the same metal binding domain, gives rise to the formation of a supramolecular metallogel on reaction with AgBF4 at 5 wt% in MeCN, possessing self-healing properties.

Does clinical validation and the implementation of new models of outpatient service delivery have the potential to reduce waiting lists? A pilot study in Letterkenny University Hospital.

Introduction: The traditional outpatient paradigm of seeing patients prior to diagnostic tests and treatment is unsustainable without additional funding. New models of service delivery such as "one-stop clinics", direct access to diagnostics and advanced nurse practitioner (ANP)-led clinics have the potential to improve the efficiency of existing services.

Methods: To determine the most effective changes to improve service provision, the reasons for encounter (RFE) to a urology clinic were assessed using the International Classification Primary Care.
