“Crystal-clear” method distinguishes between glass and fluids

The colloids that were used for the model: particles, each with a diameter of approximately 150 nm, suspended in water. The solid nucleus consists of the plastic polystyrene, the surrounding shell of a thermosensitive poly(N-isopropyl-acrylamide) network. By lowering the temperature, each individual particle’s volume—and, by definition, its packing density—can be increased. Photo: HZB/M.

Fluoride’s Unexpected Role In Photocatalysis-Materials: Acid’s surface residue, not just the catalyst, should get credit

Using HF in TiO2 synthesis (left) changes the crystals’ morphologies and facets relative to an HF-free method (right), as seen in these TEM images, and may unexpectedly alter the crystals’ catalytic properties.

Polymorphs-DRUGS

DRUG POLYMORPHISM New Drugs The US Food and Drug Administration (FDA) require submitters of an Investigational New Drug Application (INDA – new drug) to submit polymorph information. New Generic Drugs The US FDA requires submitters of an Abbreviated New Drug Application (ANDA – new generic) that they must include a polymorphism study in order to… Continue reading Polymorphs-DRUGS
