Fiber Reinforcement of Soft Spider Silk Hydrogels

open access: yesMacromolecular Rapid Communications, EarlyView.
Along the development of matrices for biomedical applications, precise tuning of the biomaterial to interact with specific cell types/tissues is essential. The fabrication of fiber mesh‐reinforced soft hydrogels made of recombinant spider silk proteins allows for the adjustment of mechanical properties and hydrogel porosity, leading to improved cell ...

Separation of Thiourea and Ammonium Thiocyanate

open access: yesBUNSEKI KAGAKU, 1954
Ammonium thiocyanate and thiourea are interchangeable isomers. The authors found that treating a mixture of these two with mercuric chloride gives a precipitate of thiourea above pH 4, while the ammonium thiocyanate does not give precipitate below pH 6; thus, the thiourea is precipitated with mercuric chloride at pH 46 to separate from ammonium ...
