Multifunctional hybrid alginate-based hydrogels for cell immobilization

Luca Szabó

Cell therapy could be a solution for many diseases that currently pose a huge health burden on patients. Especially, cell therapies based on cell microencapsulation are of great interest. Immunoprotection of cells would allow to avoid the need for immunosu ...

Experimental evidence for long-range stabilizing and destabilizing interactions between charge and radical sites in distonic ions

Ganna Gryn'ova

Polarizable radical sites in distonic radical anions are stabilized by ostensibly remote negative charges. Computational evidence suggests bond dissociation energies of closed-shell precursors are significantly lowered by through-space interactions with a ...

Extrinsic Defects in Amorphous Oxides: Hydrogen, Carbon, and Nitrogen Impurities in Alumina

Alfredo Pasquarello, Francesco Ambrosio, Zhendong Guo

We present a procedure for addressing extrinsic defects in amorphous oxides, in which the most stable defect configurations are identified through ab initio molecular dynamics in various charge states and studied through hybrid functional calculations. The ...

Kinetic modeling of lag times during photo-induced inactivation of E. coli in sunlit surface waters: Unraveling the pathways of exogenous action

César Pulgarin, Stefanos Giannakis, Jean Arnaud Troyon

This work presents a kinetic analysis of the exogenous photo-induced disinfection of E. coli in natural waters. Herein, the inactivation of bacteria by light and photo-generated transient species, i.e., hydroxyl radical (HO center dot), excited triplet sta ...

Enhanced mineralization of atrazine by surface induced hydroxyl radicals over light-weight granular mixed-quartz sands with ozone

Stefanos Giannakis, Jun Ma, Da Wang, Shuang Song

A light-weight granular mixed-quartz sand (denoted as L-GQS) combined with stirring-assisted bubble column reactor was firstly applied in catalytic ozonation of atrazine. The L-GQS, with a density of 2.36 g cm(-3) and average diameter of ca. of 4 mm, was r ...

Reactions of aliphatic amines with ozone: Kinetics and mechanisms

Urs von Gunten, Sung Eun Lim

Aliphatic amines are common constituents in micropollutants and dissolved organic matter and present in elevated concentrations in wastewater-impacted source waters. Due to high reactivity, reactions of aliphatic amines with ozone are likely to occur durin ...

Spontaneous ecological recovery of vegetation in a red gypsum landfill: Betula pendula dominates after 10 years of inactivity

François Gillet

Red gypsum is the product of the neutralization of titanium dioxide (TiO2) extraction residue from ilmenite and anatase. The disposal of red gypsum creates heterogeneous plots with layers that may include Fe, Ca, Al, Mg, Mn, S, and other elements and an al ...

Comparing the anti-bacterial performance of chlorination and electrolysis post-treatments in a hand washing water recycling system

Odile Marie Clotilde Hervás de Nalda-Larivé

Innovative solutions are necessary to enable the decentralized recycling of greywater for applications requiring high-quality water, such as hand washing. While physical barriers such as ultrafiltration membranes effectively prevent the passage of bacteria ...
