Graphene (/ËÉ¡rÃ¦f.iËn/) is an allotrope of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes.
Proton pump inhibitors are a type of acid reducer that helps to decrease levels of acid in your stomach. They work by causing your body to make less stomach acid. This helps to treat heartburn and acid reflux problems. Another type of acid reducer, in addition to a proton pump inhibitor, is an H2 blocker.
Proton pump inhibitors (PPIs) are a class of drugs used to treat heartburn, gastroesophageal reflux disease (GERD), and gastric ulcers. Heartburn and GERD are quite common. Heartburn is the main symptom of GERD but does not always signal it (see section 2 for a more detailed explanation).
