Occasionally referred to as ‘colloidal gold,’ gold colloid is a suspension comprising sub-micron gold nanoparticles suspended in a solvent - most commonly water. Gold nanoparticles' distinct ...

Being abundant in nature, colloids find increasingly important applications in science and technology, ranging from direct probing of kinetics in crystals and glasses to fabrication of ...

THE second edition of this work, like the first, is well adapted to introduce the general student to the subject, the theoretical portions and the accounts of experimental procedure being well ...

Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light. Scientists have devised a way of ...

Colloidal gold consists of microscopic particles of gold suspended in liquid and is usually red or purple. It comes from shale or clay deposits. There has been much debate about the health benefits of ...

THIS work can claim to meet a long-felt want with more justice than the majority of publications heralded by that familiar phrase. Until its appearance it has been necessary to refer students to ...
