Ecopulse, Inc., is Nino R. Pereira's Small Business. Before his retirement, around 2020, it was the contract vehicle for his contract research with the US Government. Many were done in cooperation with two major US Defense laboratories in the Washington DC area, the Naval Research Laboratory and the Army Research Laboratory. Papers resulting from this work can be downloaded below (in 'papers'). Ecopulse has continued some work with with curved crystals: see below.

• Spherically curved crystals are widely used for imaging with monochromatic x-rays, and for x-ray spectroscopy. Some examples are here.
• Papers in the archival literature written by or with Nino. R. Pereira can be downloaded here.
• Studies of nuclear isomers. In the early 2000's some people thought that the energy stored in nuclear isomers could have military applications. This is not so, I believe. Some of our work on the topic, including one (of many) reason for my negative opinion about its practicality, can be found here.
• Hard x-ray spectroscopy with curved x-ray transmission crystals (originally developed by Mme Cauchois, and brought to pulsed power research by John Seely) to is one of the many diagnostic techniques that have been used on the Naval Research Laboratory's venerable Gamble II generator. At the time this web site was originally written, the results were very interesting. Hence, some typical results are here.
• X-ray transparent lithium and some of its alloys make good x-ray windows. How to make lithium and its alloys easier to handle and stronger is documented here.
• Refractive x-ray lenses made from lithium metal, which is slightly better than beryllium in transmitting x-rays. Some results are here.
• Personal data here.
