At present, additively manufactured biomedical materials find extensive applications in a wide range of avenues ranging from orthopaedics to urology. Additive manufacturing (AM) techniques based on the layerwise deposition of materials allow fabrication of complex-shaped biomedical components with a high level of accuracy. In this context, the major challenge is to obtain robust and functional engineering...

The ability to form strong intermolecular interactions by linear glucosamine polysaccharides with collagen is strictly related to their nonlinear dynamic behavior and hence bio-lubricating features. Type III collagen plays a crucial role in tissue regeneration, and its presence in the articular cartilage affects its bio-technical features. In this study, the molecular dynamics methodology was applied...

New protocol for screening efficient and environmentally friendly solvents was proposed and experimentally verified. The guidance for solvent selection comes from computed solubility via COSMO-RS approach. Furthermore, solute-solvent affinities computed using advanced quantum chemistry level were used as a rationale for observed solvents ranking. The screening protocol pointed out that 4-formylomorpholine...

The miscibility of active pharmaceutical ingredients with excipients is an important aspect in pharmaceutical technology protocols. In this study, the differential scanning calorimetry (DSC) was used for Sulfamethazine-Urea (SI-U) and Sulfamethizole-Urea (SO-U) solid-liquid phase diagrams determination. Both sulfonamides form simple binary eutectics with Urea. The lack of new co-crystal phase formation...

Environmental pollution and global warming cause serious problems in human life. Since the demand for our human daily appliances had been increased by years, the organic chemical-based industries response that demand increment by increasing their production process. Because of that, the environmental pollution becomes worse and worse. Green chemistry thus was introduced to influence the chemical industries...

The aim of the present work was to study the influence of elevated temperatures on the thermal behavior of geopolymer cements based on the incorporation of metakaolin with cement kiln dust. Geopolymer composites were synthesized by partially substituted metakaolin (MK) with 0, 20, 30 and 40 wt% of cement kiln dust (CKD). The mixture of liquid sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) was...

Solubility enhancement of poorly soluble active pharmaceutical ingredients is of crucial importance for drug development and processing. Extensive experimental screening is limited due to the vast number of potential solvent combinations. Hence, theoretical models can offer valuable hints for guiding experiments aimed at providing solubility data. In this paper, we explore the possibility of applying...

The lubrication mechanism in synovial fluid and joints is not yet fully understood. Nevertheless, intermolecular interactions between various neutral and ionic species including large macromolecular systems and simple inorganic ions are the key to understanding the excellent lubrication performance. An important tool for characterizing the intermolecular forces and their structural consequences is...

In this study, the temperature-dependent solubility of nicotinamide (niacin) was measured in six neat solvents and five aqueous-organic binary mixtures (methanol, 1,4-dioxane, acetonitrile, DMSO and DMF). It was discovered that the selected set of organic solvents offer all sorts of solvent effects, including co-solvent, synergistic, and anti-solvent features, enabling flexible tuning of niacin solubility...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as a novel coronavirus in late 2019, since then it is infecting people and spreading efficiently among humans worldwide, causing the infectious disease named coronavirus disease 2019 (COVID-19). Some patients infected with SARS-CoV-2 develop severe inflammatory‐induced lung injury as a result of a cytokine storm syndrome (CSS),...
