Aging phenomena often play a key role in realistic rendering: excepting when the desired result is specifically a brand-new virtual object, their absence can lead to non-realistic surfaces, looking too clean and smooth. To solve these problems, artists either compose multiple textures manually, or directly modify object geometries. However, such techniques may not be suitable to obtain realisti...

Transport of bacteria is an important aspect from scientific, industrial and environmental point of view. In this work, a one-dimensional mathematical model based on linear equilibrium adsorption of bacteria has been developed to predict bacterial transport through porous media. This model is more realistic than existing models because of its coupling both physicochemical and biological phenome...

Protein corona has became a prevalent subject in the field of nanomedicine owing to its diverse role in determining the efficiency, efficacy, and the ultimate biological fate of the nanomaterials used as a tool to treat and diagnose various diseases. For instance, protein corona formation on the surface of nanoparticles can modify its physicochemical properties and interfere with its intended f...

The direct transfer of genetic material into cells by electroporation can be described in physicochemical terms as an electroporation-resealing hysteresis. The hysteresis concept includes unidirectional state transitions of the membrane, coupled to electrodiffusive migration of DNA through cell wall structures and electroporated plasma membranes. Deeper insight into electroporation phenomena su...

An important quality of yeast cell wall is the ability to adhere to other cell walls or solid surfaces. This feature of yeast is responsible for technologically important phenomena such as flocculation at the end of beer fermentation and cell adhesion to immobilization supports e.g. spent grains, DEAE-cellulose etc. Physicochemical properties of yeast surfaces, e.g. hydrophobicity and surface c...

In this work, we examine whether tenth-grade high school students (N = 197, age 1516) as well as first-year university chemistry students (N = 77, age 18-19) can make the connection between chemical reactions and chemical phenomena. We used nineteen physical and chemical phenomena, and asked the students at one stage to distinguish physical from chemical phenomena, and at another stage to state...

The counterdiffusion of gases across a composite layer can lead to supersaturation and development of bubbles within the layer. A physicochemical model has been derived to predict the extent of such supersaturation; experiments with inert liquid layers confirm predictions. These findings explain the evolution of cutaneous lesions observed in man during simulated deep-sea dives and the cutaneous...
