In the title compound, C(14)H(17)N(3)O(2)·0.5H(2)O, the asymmetric unit consists of an N,N'-(phenyl-imino-dimethyl-ene)diprop-2-enamide mol-ecule and one half-mol-ecule of water, with the O atom of the latter having 2 site symmetry. The supra-molecular architecture is framed by the inter-play of two-dimensional networks of both O-H⋯O and N-H⋯O inter-actions supported by C-H⋯O and edge-to-face C-H⋯π inter-actions.

A tetracalcium phosphate/monetite/calcium sulfate hemihydrate powder cement mixture (CAS) in the form of a paste was used as a socket preservative to prevent alveolar ridge resorption after the extraction of the second premolar tooth in the mandible of a pig model. During the post-surgery period, the animals were monitored daily. No signs of inflammation, infection, or other complications were observed in the defect site for six months.

The waste sulfuric acid solution emerged as a main emission substance from titanium dioxide production is called titanium white waste acid (TWWA). The disposal of TWWA has been a concern due to its potential impact on the environment. A green way including one-step preparation and purification stages of α-calcium sulfate hemihydrate (α-HH) from TWWA and lime mud via a neutralization reaction in the hydrothermal pressure apparatus was developed.

Chronic wounds present significant clinical challenges due to the high risk of infections and persistent inflammation. While personalized treatments in point-of-care settings are crucial, they are limited by the complex fabrication techniques of the existing products. The calcium sulfate hemihydrate (CSH)-based drug delivery platform enables rapid fabrication but lacks antioxidant and antibacterial properties, essential to promote healing.

Selective control over crystallization in complex multicomponent systems such as hydrating cements is a key issue in modern material science. In this context, rational selection-based approaches appear highly promising in the quest for new additive chemistries. Here we have used phage display to identify peptide structures showing high affinity to adsorb on the surfaces of calcium sulfate hemihydrate (also referred to as bassanite), an important hydraulic binder employed in large scales by the construction industry.

Phosphogypsum (PG) constitutes a form of solid byproduct emanating from the manufacturing process of wet-process phosphoric acid. The fabrication of one metric ton of wet-process phosphoric acid entails the generation of approximately five tons of phosphogypsum, a highly prolific and economically viable waste stream. If we can effectively solve the problem of poor hydrophobicity of phosphogypsum, it is possible to replace cement and other traditional cementitious materials.
