The Lorenz curve

open access: yes, 2017
Existing HIV care cascade metrics fail to capture whether viremia is equally distributed in a population or concentrated within groups. We applied the Lorenz curve, which has been used to describe disparities in the distribution of income and other resources, to the distribution of viremia in a safety-net HIV clinic in 2012.

g‐C3N4 Nanosheet/ZnO Nanosponge Heterojunctions for Efficient Visible‐Light Photocatalytic Degradation of Methylene Blue

open access: yesChemNanoMat, EarlyView.
ZnO nanosponge/g‐C3N4 nanosheet heterojunctions are developed as UV‐ and visible‐light photocatalysts for methylene blue degradation in water. The 3D ZnO nanosponge provides high porosity and fast UV activity, while the 2D/3D type‐II junction with g‐C3N4 enables efficient visible‐light degradation (98% removal in 60 min with an apparent rate constant k

Estimating the Empirical Lorenz Curve and Gini Coefficient in the Presence of Error [PDF]

open access: yes, 2007
The Lorenz curve is a graphical tool that is widely used to characterize the concentration of a measure in a population, such as wealth. It is frequently the case that the measure of interest used to rank experimental units when estimating the empirical ...

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...
