The purpose of this paper is to describe how molecules in a fluid move (permeate) through a solid material. The paper will describe permeation on a molecular level and discuss the general relationships between different types of fluids and different forms of solid materials. A general ...
Flavanoids are the largest and most important group of natural polyphenolics with more than 6000 molecules identified so far. Other classes include phenolic quinones, lignans, xanthones, coumarines, polymeric lignins and tanins [5]. Within each class of compounds, the variations around the basic ...
Adding borate ions causes these molecules to tangle and form a thicker, rubbery substance—slime! Think of it like wet spaghetti turning into a clump of leftovers as the molecules bind together. Is slime a liquid or solid? It’s both! Slime is a Non-Newtonian fluid, meaning its viscosity ...
Crystals, on the other hand, aren't at all haphazard. A crystal is a form of solid where the atoms are arranged in a predictable, specific pattern. Not all substances can form crystals because they're very delicate and specific. The atoms in a crystal form a repeating pattern called a ...
Molecules of ECM, newly liberated by injury or inflammation, include hyaluronan fragments, tenascins and sulfated proteoglycans. These act as ‘damage-associated molecular patterns’ or ‘alarmins’ that trigger and subsequently amplify inflammation [138]. Curcumin possess the effects of the anti-...
of water molecules and phase changes of water. This study is qualitative and draws on the frameworks of social semiotics and Designs for Learning, DfL, where teaching and learning are seen as a multimodal design. The Learning Design Sequence model, developed within DfL is used as a basis for...
The glue is a polymer of long, repeating, and identical strands or molecules. These molecules with flow past one another and keep the glue liquid. Until… You add the borate ions to the mixture, and it then starts to connect these long strands together. They begin to tangle and mix until...
Tomographic methodsThese methods create a series of 2D slices to generate a 3D volume and provide non-destructive, high-resolution data of external and internal structures or even the movement of small molecules through a root system in the case of plants. X-ray computed tomography (CT), magnet...

Laminar flow: One key aspect of the microfluidic world is the laminar flow regime that prevails at these length-scales. Low Reynolds number flows reduce flow dispersion and allow for precise control of flow behavior. Mixing of molecules between solutions is mostly due to diffusion at this length...
