1Post-synthesis phase and shape evolution of CsPbBr3 colloidal nanocrystals: The role of ligands显示文摘The surface chemistry of colloidal cesium lead bromide (CsPbBr3) nanocrystals is decisive in determining the stability and the final morphology of this class of materials,characterized by ionic structure and a high defect tolerance factor.Here,the high sensitivity of purified colloidal nanocubes of CsPbBr3 to diverse environmental condition (solvent dilution,ageing,ligands post synthetic treatment) in ambient atmosphere is investigated by means of a comprehensive morphological (electron microscopy),structural (θ/2θ X-ray diffraction (XRD) and grazing incidence wide angle scattering (GIWAXS)),and spectroscopic chemical (1H nuclear magnetic resonance (NMR),nuclear Overhauser effect spectroscopy (NOESY),absorption and emission spectroscopy) characterization.The aging and solvent dilution contribute to modify the nanocrystal morphology,due to a modification of the ligand dynamic.Moreover,we establish the ability of aliphatic carboxylic acids and aikyl amines ligands to induce,even in a post preparative process at room temperature,structural,morphological and spectroscopic variations.Upon post synthesis alkyl amine addition,in particular of oleyl amine and octyl amine,the highly green emitting CsPbBr3 nanocubes effectively tum into one-dimensional (1 D) thin tetragonal nanowires or lead halide deficient rhombohedral zero-dimensional (0D) Cs4PbBr6 structures with a complete loss of fluorescence.The addition of an alkyl carboxylic acid,as oleic and nonanoic acid,produces the transformation of nanocubes into still emitting orthorombic two-dimensional (2D) nanoplates.The acid/base equilibrium between the native and added ligands,the edsorbed/free ligands dynamic in solution and the ligand solubility in non-polar solvent contribute to render CsPbBr3 particularly sensitive to environmental and processing conditions and,therefore prone to undergo to structural,morphological and,hence spectroscopic,transformations.Elisabetta Fanizza Francesca Cascella Davide Altamura Cinzia Giannini Annamaria Panniello Leonardo Triggiani Francesca Panzarea Nicoletta Depalo Roberto Grisorio Gian Paolo Suranna Angela Agostiano M.Lucia Curri Marinella Striccoli 2019Nano Research2019,12,5:2

8Compliance in patients with dietary hyperoxaluria: A cohort study and systematic review显示文摘Objective:Hyperoxaluria leads to calcium oxalate crystal formation and subsequent urolithiasis.This study aims to analyse the effect of treatment compliance in hyperoxaluria,firstly by analysis of patients with non-primary hyperoxaluria and secondly via systematic review in patients with any hyperoxaluria.Methods:In a retrospective cohort study,adults with non-primary hyperoxaluria managed with dietary counselling in 2013 were enrolled.Twenty-four-hour(24 h)urine collections initially and at 6 months were obtained.Compliance was assessed by self-reported dietary compliance and 24 h urinary volume>2 L.Patients were followed for 24 months.Primary outcomes were urinary oxalate and calcium 24 h load at 6 months,and urolithiasis-related procedural rates at 24 months.A Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)-compatible systematic review of compliance among hyperoxaluric patients was performed.Results:In the cohort study,of 19 eligible patients(4 female)with median age 52 years,10(53%)were considered compliant.Compared with the non-compliant group,these patients had significantly increased subsequent 24 h urinary volume(2250 mL vs.1600 mL;p=0.008)and lower procedural rates(10%vs.56%;p=0.033).Subsequent 24 h urinary oxalate load was nonsignificantly lower in compliant patients.Systematic review regarding compliance in hyperoxaluric patients revealed five studies.Only one utilised dietary counselling or analysed compliant vs.non-compliant patients,finding no difference.None examined the effect of compliance on procedural rates.Derek B.Hennessey Ned Kinnear Gilbert Rice David Curry Siobhan Woolsey Brian Duggan 2019Asian Journal of Urology2019,6,2:1
