Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

Students learn to classify matter as elements, compounds, and mixtures. Matter: Classification of Matter: Students learn to classify matter as elements, compounds, and mixtures and to distinguish ...

The conceptual and technical approaches that led to the explosive growth of combinatorial chemistry began approximately 20 years ago. In the past decade, combinatorial chemistry has continued to ...

Physicists have developed a novel technique that can detect molecular variants in chemical mixtures -- greatly simplifying a process that is one of the most important, though time-consuming, processes ...

When hearing someone describe the typical preparation of organosulfur compounds, it’s clear the approach is not a very sustainable one. Mixtures of sulfur compounds naturally in crude oil are first ...

Nuclear magnetic resonance (NMR) spectroscopy is a powerful technique used to identify and quantify the constituents of complex mixtures. Each nucleus of an atom which has a non-zero spin quantum ...

A solid sorbent that selectively binds hydrocarbons may help the petrochemical industry reduce costs and energy consumption by increasing the efficiency of—or eliminating—energy-intensive separation ...
