Discusses flyback and forward converter topologies used in switch-mode power-supply design. Limitations of the flyback and forward converter topologies; Comparison between flyback converters and forward...
Modern society is striving for digital connectivity that demands information security. As an emerging technology, printed electronics is a key enabler for novel device types with free form factors, customizability, and the potential for large-area fabric
While all of the three tested sealings had high transmittance (> 91%) in the visible spectrum (VIS) (Fig.5A), the tested materials differed strongly in the proportion of transmitted diffuse light (Table1). The ratio of both is described by the Haze index, according to standard test met...
Phased arrays are multiple antenna systems capable of forming and steering beams electronically using constructive and destructive interference between sources. They are employed extensively in radar and communication systems but are typically rigid, bul
This means that we were offline for 399 hours (which corresponds to 16.64 days). These numbers don’t tell the whole story, though. During the first ten months of this period, the server was online for 98.2% of the time. This means that it was offline for only 152 hours (6.4 days)...

Two-dimensional (2D) magnets offer valuable electrical and mechanical properties, and could be used to create 2D nanoelectromechanical systems. However, the low Curie temperature of most 2D magnets limits practical applications. Here we report van der Wa
Although seawater is abundant, desalination is energy intensive and expensive. Using the Sun as an energy source is attractive for desalinating seawater. Although interesting, current passive devices with no moving parts have unsatisfactory performance w
