The radical cations of a family of π-conjugated porphyrin arrays have been investigated: linear chains of N = 1–6 porphyrins, a 6-porphyrin nanoring and a 12-porphyrin nanotube. The radical cations ...

In this work we have studied the effects of high neutron fluencies and gamma doses on the structural properties of three different types of silica glasses: two high purity silica with different OH ...

A Down Under infrastructure acquisition from Brookfield Asset Management valued at over $1 billion topped the private market transactions we tracked today.

Vibrational circular dichroism (VCD) spectra and the corresponding IR spectra of the chiral isomers of methyloxirane and of methylthiirane have been reinvestigated, both experimentally and ...

The samples were manufactured by ion milling over silver lying on an Infrasil substrate. The geometry was checked by S EM microscopy. Transmission and reflection coefficients were obtained by FTIR.

In a pre-proof article posted in the Journal of Nuclear Materials, researchers analyzed the effects of concurrent radiation and thermal annealing on optical absorption in integrated silica and ...

The Infrasil 302 silica samples were in two different geometries, 10-mm diameter hemispheres (CVI Melles Griot) and 25 mm × 2 mm windows (Korth Kristalle). The hemispheres and the windows (both heated ...

Perkins Precision Developments (PPD) manufactures custom laser windows and precision wedges in a variety of materials including fused silica, N-BK7, Infrasil and YAG. Typical options include Plane ...
