Polyacenes are actually a chain of benzene rings (see figure). It is widely believed that polyacenes would have unprecedented properties: non-linear optics, substantial mechanical strength (similar to Kevlar™) and high directional (anisotropic) conductivity; i.e. conductive in one dimension/directio.....

In line with the demands of modern society, the multidisciplinary Biomaterials and Corrosion Laboratory is conducting strategic R&D on advanced materials ranging from biomaterials and nanomaterials, to materials for space applications, alloy deposition and archaeology. The Lab also provides material.....

Adhesive skin patches are used for a wide variety of purposes. Their main disadvantages are that they may be too adhesive (difficult to remove, not adhesive enough and fall off without being noticed (contraceptive patches), and they can cause irritation. If they are too adhesive, residues may .....

WPANs operating in the 60 GHz millimeter-wave band connect personal computer devices within a few meters range and allow for intra-communication services for the devices. Tapered slot antennas (TSAs) are suited for such applications and can be used either as single antennas or as an element of an ar.....

Laser frequency can be converted very efficiently nowadays using electrically field poled ferroelectric crystals, such as LiNbO3 or KTiOPO4. Unfortunately, these crystals are readily available only with relatively small aperture – up to 1 mm in the critical Z axis of the crystal – thereby severely l.....
