Description

Nanoparticles are defined by the worldwide federation of national standards bodies, the International Organization for Standardization (ISO), as nanoobjects with all external dimensions in the nanoscale, where the lengths of the longest andshortest axes of nanoobjects do not differ significantly . Though nanoscale is basically ranged from 1 to 100 nm, nanoparticles can be categorized by three size ranges: larger than 500 nm, between 100 and 500 nm, and between 1 and 100 nm (European Commission, 2010). With respect to the size and the size distribution, nanoparticles may exhibit size-related intensive properties. If they are small enough to confine their electrons, they produce quantum effects and exhibit unexpected properties, for example, gold nanoparticles appear red in solution (see, for instance, Eustis and El-Sayed, 2006), and melt at much lower temperatures than that in slab form (Buffat and Borel, 1976). The high surface-area-to-volume ratio of nanoparticles provides the significant changes in properties related to contact/surface area, such as catalytic (Astruc, 2008),surface-enhanced plasmon resonance (Melaine et al., 2015), etc.

LATEST CHOZI LA HERI GUIDE
Jalada la Riwaya ya Chozi la Heri ni tokeo la usanii wake , Robert Kambo. Katika upande wa mbele sehemu ya juu, mna rangi ya kijani kibichi iliyokolea. Maana ya rangi hii ni uhai na rutuba. Riwayani yamo maeneo yaliyo na rutuba yanayotoa mazao mengi. Katika eneo la Msitu wa Heri alikoishi Ridhaa kwa miongo mitano, mwanzoni kulikuwa kama jangwa la Kalahari lakini Ridhaa alihakikisha kuwa kijiji hiki kimepata maji ya mabomba hadi eneo zima likatwaa rangi ya chanikiwiti. Miti mingi kama Miambakofi, mivule na miti mingine kapandwa. Maeneo mengine yaliyokuwa na rutuba ni kama Msitu wa Mamba. Watu waliogura makwao walipohamia hapa walikata miti na kupanda vyakula kama mahindi ambayo yalifanya vizuri mno.
