Students will be able to plan and carry out an investigation to compare the solubility of different substances, and develop and explain a particle-level model to describe the process of dissolving.

Secondary natural substances that occur in numerous plants, bacteria and fungi can be anti-inflammatory, can ward off pathogens or even prevent the growth of cancer cells. However, making use of the ...

Scientists have developed a novel peptide suitable for the targeted transport of molecules -- for example, active substances and dyes -- into the cells of mammals. A novel peptide developed at the ...

Breaking the chemical bonds in large molecules to form a desired substance can be a fiddly task, but simply chucking molecules at a wall can get the job done. Stephan Rauschenbach at the University of ...

Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...

Since the Middle Ages, alchemists have sought to transmute elements, the most famous example being the long quest to turn lead into gold. Transmutation has been realized in modern times, but on a ...

Per- and polyfluoroalkyl substances (PFAS) are ubiquitous substances that do not degrade in the environment and can harm ...

AT the Friday evening discourse at the Royal Institution on April 23, Prof. H. Mark discussed “The Synthesis of Large Molecules”. In Nature, all organized objects consist of large molecules. The great ...

A new technique pushes the limits of how cold molecules can get to a tiny fraction of a degree above absolute zero. The researchers used a combination of lasers and magnetic fields to trap a molecule ...

NASA's New Horizons probe conducted a flyby of Ultima Thule (MU69), the most distant object studied by humankind, revealing it as a binary body that is notably red and very dark, lacking moons or ...

For her research project entitled "Cooperative Synthesis by Molecular Deconvolution" (CoSyMoDe), Professor Tanja Gaich from the Department of Chemistry at the University of Konstanz receives a ...

More than a third of all medicines available today are based on active substances from nature and a research team has developed a procedure to identify small active substance molecules much more ...
