There are lots of researches on left-handed materials (LHM) which are mostly realized by using SRR and it has important implication for stealth of targets.
For the refractive index in negative near the resonance frequency of left-handed material unit, it is feasible to reduce the RCS of antenna by adjusting the refractive index of SRR.

However, in the process of production, processing of medicinal materials, storage, transport, due to the condition and technology simple, It is easy to mildew and produce aflatoxin.Aflatoxins (AFs) are secondary metabolites produced by Wlamentous fungi Aspergillus, particularly Xavus and parasiticus[1].

Aflatoxins analysis on spices are not simple. because of the highly coloured contaminating materials that are co-extracted with AFs.

The wettability behavior of superhydrophobic surfaces can be transformed to achieve Wettability switching under specific conditions: optical, magnetic, mechanical, chemical, thermal [14], Silicon is probably the most important material for applications such as sensors and optoelectronic devices. surfaces have been created by modifying with hydrophobic materials on nanostructured Si surface prepared by metal-assisted chemical etching (MaCE) [15,16,17], the VLS growth technique [18,19]or hierarchically double-scale (micro- and nanoscale) textured silicon surface formed by using femtosecond laser pulses in SF6 [20], a nonlithographic top-down electrochemical approach [21], deep reactive ion etching and galvanic etching [22].
Experiment The materials used for experiments were boron doped p-type single-crystalline with resistivity of 1-3 Ω cm.

Therefore, some other wide band gap semiconductor materials, e.g.
On the one hand, ZnO is a wide direct band gap semiconductor materials with 3.2 eV, the band gap is the same as TiO2.
Accordingly, ZnO as the photoelectrodes used in DSCs, has been a hot research topic in energy materials.

So the composite material elongation at break elevated.
When the fumed silica is too much, it united in the composite material, so that the material elongation at break decreased.
