Nanotechnology is a multidisciplinary field that looks at how to manipulate matter at the molecular and atomic level to produce new materials, devices, and organic structures. These materials and devices can be designed to interact with biological systems for applications in medicine and physiology, or to make objects more resistant to external effects. Nanotechnology is […]
Fact Sheet: Additive Manufacturing
Additive manufacturing (AM) is an emerging means of production in which objects are created by layering materials in precise geometric shapes according to a predetermined design. This contrasts with traditional “subtractive” manufacturing in which material is pared, milled, carved, or otherwise reduced to shape an object. Additive manufacturing refers to the general manufacturing process that […]
The Right and Wrong Lessons to Learn from Missile Defense in Ukraine
By Shawn Rostker The war in Ukraine has been marked by a Russian reliance on air strikes in the face of its failure to capture decisive victory on the ground. The use of drones and missiles against military and civilian targets has been one of the main pillars of a Russian strategy to drain Ukraine’s […]
Fact Sheet: Depleted Uranium
What is Depleted Uranium? Depleted uranium (DU) is a toxic heavy metal and the main by-product of uranium enrichment. Uranium left over from the enrichment process is called “depleted” because it has only about one-third as much U-235 as natural uranium. DU is not usable for nuclear weapons as it does not contain enough fissile […]
No Good Reason for Nuclear Testing
By John Erath On October 5, Russian President Vladimir Putin stated that Russia would consider revoking its ratification of the Comprehensive Test Ban Treaty (CTBT) and turned the matter over to the Duma for further action. This step has caused concern that Russia may resume explosive testing of nuclear weapons and break the effective moratorium […]
