Despite several decades of active experimental and theoretical studies rare-earth orthoferrites, the mechanism formation their specific magnetic, magnetoelastic, optical, magneto-optical properties remains a subject discussion. This paper provides an overview simple model approaches to quantitatively describing structure–property relationships—in particular, interplay between FeO6 octahedral de...
Polymeric gels belong to the most important class of functional polymers in modern biotechnology. They are useful materials for drug delivery systems, artificial organs, separation operations in biotechnology, processing of agricultural products, on–off switches, sensors, and actuators. Despite this fact and considerable research in this field, the design and control of gel-based devices still ...
The replacement of a carboxylic acid with a surrogate structure, or (bio)-isostere, is a classical strategy in medicinal chemistry. The general underlying principle is that by maintaining the features of the carboxylic acid critical for biological activity, but appropriately modifying the physicochemical properties, improved analogs may result. In this context, a systematic assessment of the ph...
Structure-property relationships were obtained for 11 physical and chemical properties (boiling points (bp), melting points (mp), molar refractions (MR), molar volumes (MV), heats of combustion (HCKJ), molar heats of vaporization (HVMOL), flashpoints (FLASHK), second virial coefficients (VIRC2), critical temperatures (Tc), critical pressures (Pc), and viscosities (VISC)) for a data set consisti...
Silicon nitride (Si3N4) is an industrial ceramic used in spinal fusion and maxillofacial reconstruction. Maximizing bone formation and minimizing bacterial infection are desirable attributes in orthopedic implants designed to adhere to living bone. This study has compared these attributes of Si3N4 implants with implants made from two other orthopedic biomaterials, i.e. poly(ether ether ketone) ...
