We investigated the influence of the reduction state of gold ions on the growth of gold nanocrystals in N,N-dimethyl formamide (DMF). While freshly prepared solutions of AuCl3 produce spherical nanocrystals, aged precursor solutions containing mainly Au+ ions and Au(0) atoms lead to various branched nanoparticles. Furthermore, we show that also the amount of the reducing and stabilisation agent...

Media psychology and telemedicine: the growing professional opportunity Telecommunication is a powerful force for helping to improve world health. While telemedicine has been prominent in health care for many years, media psychology is acknowledged only now as having central strategic importance in improving all aspects of telecommunications. For the purposes of this discussion, telemedicine is...

We present the microscopic equation of growing interface with quenched noise for the Tang and Leschhorn model [L. H. Tang and H. Leschhorn, Phys. Rev. A 45, R8309 (1992)]. The evolution equation for the height, the mean height, and the roughness are reached in a simple way. An equation for the interface activity density (or free sites density) as function of time is obtained. The microscopic eq...

this paper deals with the suitability of agricultural and municipal organic wastes as growing media components for ornamental plants. nine growing media prepared by mixing the main components of peat (p), hazelnut husk (h) and maize straw (m) with the fertilizer sources of municipal solid waste compost (c), bio-solid (b) and poultry manure (pm) were compared against soil-based (c1) and peat-bas...

Zeolite has many good features that makes it very attractive for nursery use as a growing media over others. This study was designed to investigate influence of different growing media and their mixtures (with zeolite and without zeolite) on morphological characters of scots pine seedlings. Twenty-one treatments of varying amounts of peat, fine pumice, coarse pumice, river sand, perlite and riv...

Coffee is one of the plantation commodities that play an important role as a source foreign exchange for country. One alternative to overcome land decrease in rural area utilize urban farming form vertical planting system. This study aimed obtain techniques coffee seedlings using and determine effect with several growing media on growth seedlings. The was arranged non-factorial Randomized Block...
