, 1999 There is an electromagnetic factor of correlation between gravitational mass and inertial mass, which in specific electromagnetic conditions, can be reduced, made negative and increased in numerical value. This means that gravitational forces can be reduced, inverted and intensified by means of electromagnetic fields.

Trapping Xe in Nanocages Using a Plasma
Small Science, EarlyView.Silicate nanocages supported on metal powders trap xenon (Xe) atoms when exposed to a Xe plasma. Three major advances are achieved in this work including trapping Xe in (1) high‐surface‐area powder materials, using (2) a nonprecious metal support, and (3) a simple ionization method.

Self‐Driving Microscopes: AI Meets Super‐Resolution Microscopy
Small Methods, EarlyView.This review examines the use of machine learning to automate super‐resolution optical microscopy, enabling the microscope to autonomously make decisions on what, when, and how to image. By eliminating the need for human intervention, this approach has the potential to enhance the versatility and accessibility of super‐resolution microscopy.

Spacecraft and Instrumentation
, 2016 The new scientific work in this thesis stems from data gathered and returned to Earth by the Cassini-Huygens spacecraft. Onboard the spacecraft is a suite of in situ instruments making field, particle and wave measurements for studying dust, plasma and magnetic fields around Saturn. There are also suites of optical remote sensing instruments (e.g.
