The chromophore of visual pigments was efficiently extracted in its original isomeric conformation by dichloromethane/hexane in the presence of excess formaldehyde. This new method of extraction (the formaldehyde method) in combination with HPLC is useful for the determination of the chromophore composition of visual pigments. The chromophore isolated by(More)
Context. Measurements of intracluster gas temperatures out to large radii, where much of the galaxy cluster mass resides, are important for using clusters for precision cosmology and for studies of cluster physics. Previous attempts to measure robust temperatures at cluster virial radii have failed. Aims. The goal of this work is to measure the temperature(More)
