Tunable Synthetic Hydrogel Modulates Hepatic Lineage Specification of Human Liver Organoid

open access: yesAdvanced Functional Materials, EarlyView.
In this study, a synthetic hydrogel is reported that supports the formation of hiPSC‐derived human liver organoids (HLOs). Hepatic lineage specification can be modulated via conjugation of RGD peptide to hydrogel: RGD‐conjugated hydrogels promote cholangiocyte differentiation, whereas RGD‐free hydrogels favor hepatocyte commitment of HLO cells.

A prototype for on-site generation of chlorinated disinfectant for use in rural aqueducts

open access: yesWater Science and Engineering
Sodium hypochlorite has significant potential as a sanitation solution in hard-to-reach areas. Few studies have investigated the optimal electrolysis parameters for its production with volumes greater than 10 L.

Composition of waters of lakes and rivers in east and west Africa [PDF]

open access: yes, 1974
Thirty-three groups of geochemically related natural lake and river waters collected from 368 sites scattered over East and West Africa, were investigated to determine correlations between their various ions and the patterns of change in their ionic ...

Calcium Imparts Advanced Functionalities to Silk Hydrogels for Biofabrication and Biomedical Innovation

open access: yesAdvanced Functional Materials, EarlyView.
The addition of calcium ions to silk fibroin enhances the hydrogel properties and, when combined with visible light crosslinking, enables compatibility with advanced light‐based fabrication techniques. Calcium ions extend the shelf‐life of silk and facilitate the fabrication of multizonal, multilayered constructs for advanced stimuli‐responsive ...

SALT TOXICOSIS IN POULTS - A CLINICAL REPORT [PDF]

open access: yesJournal of Veterinary and Animal Sciences, 2003
Sodium (Na+) is the toxic ion in salt toxicosis of domestic fowls. Sodium chloride (common salt) is generally thought of as providing the majority of Na+ found in the diet. However, other sources of sodium such as sodium bicarbonate, can also contribute

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

open access: yesAdvanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...
