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 ...
resulting in lower energy levels. In contrast, molecules in the amorphous state are highly disordered, resulting in higher surface free energy and higher energy levels compared to crystalline substances. This makes them easier to disperse, increases their dissolution rate, and improves the drug's bio...
Think of it like spaghetti. Freshly cooked spaghetti is loose and slippery, but when it cools and sits, it becomes a clump. That’s similar to how the slime’s molecules get tangled up, making it thicker and more rubbery. Is slime a liquid or solid? We call it a non-Newtonian fluid...
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 ...
These states are divided based on the way that molecules behave within each one. Take water as an example: As a solid, water takes the form of ice. Ice is made up of neutrally charged atoms arranged in a hexagonal pattern that forms a solid. Because the molecules stay fairly still ...
However, there is an emerging role of Ca2+ and related proteins in cell motility, growth, migration, proliferation and tumor cell formation [8,9]. Control of intracellular Ca2+ levels is regulated through Ca2+ channels and its stores in the endoplasmic reticulum [10]. There are two categories...
student interpretations of representations seem to be different than the intended meanings of the textbook representations. Finally, the student and textbook representations are similar in terms of the types of particles and the distances among them, while they are different from each other in terms ...
They also found both the pore and the capsid deform as it goes. Interestingly, the lattice of molecules that make up the capsid structure develops little regions of less order to accommodate the stress of the pressure. “It’s not like a solid compressing or expanding, as...
The Intergovernmental Panel on Climate Change has shown that 79% of carbon dioxide comes from burning fossil fuels that are used to generate electricity in coal-fired power plants, which are responsible for up to 60% of all CO2 emissions [3]. Despite the intensive development of Carbon Capture...
Thus, research to date suggests that chronic inflammation, oxidative stress, and most chronic diseases are closely linked, and the antioxidant properties of curcumin can play a key role in the prevention and treatment of chronic inflammation diseases. Keywords: curcumin; antioxidant; inflammation; ...
