Introducing a novel silicon-on-insulator optical metamaterial waveguide that is compatible with CMOS technology

An optical waveguide is defined as a structure that can confine and guide optical light to follow a predefined path from a transmitter to a receiver. The waveguide that we are discussing is made of silicon semiconductor material that is built over a bulk insulating substrate made of silicon dioxide material. This silicon-on-insulator structure is fabricated with a well-known, simple, […]

Optimisation of truck-drone parcel delivery using GRASP

Professor Sarab AlMuhaideb has developed a new algorithm to minimise the delivery time for combined truck and drone delivery

Parcel delivery has traditionally been handled by trucks, but rapid technological developments in autonomous unmanned aerial vehicles means that drones are now being used to support parcel delivery. Professor Sarab AlMuhaideb and the research team at King Saud University, Saudi Arabia, have developed an algorithm that minimises the total delivery time for combined truck and drone delivery. The researchers have […]

Using nanoparticles for effective immune system modulation

Written by

The development of nanoparticles is increasingly becoming an essential strategy in drug delivery. Professor Aws Alshamsan from King Saud University, Saudi Arabia, is an expert in the field of nanobiotechnology and designs drug delivery systems made of small synthetic polymers to target specific tissues with high effectiveness. These particles are internalised by the immune system, along with the drugs that […]
