Introduction The terahertz (THz) electromagnetic wave has long been recognized as an important electromagnetic wave for scientific research because of its high transmittance, coherence, and THz spectroscopy for novel information in chemistry and biochemistry [1-3].
In order to well understand the THz wave propagation through the FSS structure and THz E-field distribution on FSS structure, the unit cell was modeled using a finite difference time domain method in which the structure was designed to be resonant at 1.3 THz.

and structure.
Hepatocytes are cultivated inside capillary membranes embedded in a collagen matrix [1, 2], microbeads entrapped in capillary systems [3], three-dimensional woven structures of capillaries [4], polyamide hollow fibers, cellulose and polypropylene [2, 3, 5], reticulated polyurethane [6] and different nonwoven materials [7, 8].
This nanofiber matrix can be produced in large quantities using the Nanospider™ electrospinning technology [9] and utilized eventually to form three dimensional structures.
Note the nanoporous structure of the polycaprolactone nanofibers.

Synthesis of Silver Nanoparticles Using o-Hydroxybenzoic, p-Hydroxybenzoic, and o,p-Dihydroxybenzoic Acids as Reducing Agents DIAN Susanthya, FADLIAHb, ENDANG Tri Wahyunic and SRI JUARI Santosad * Department of Chemistry, Universitas Gadjah Mada, Sekip Utara, Bulaksumur, Yogyakarta 55281 Indonesia adiansusanthy@mail.ugm.ac.id, bfadliah@mail.ugm.ac.id, cendtriw@yahoo.com, dsjuari@ugm.ac.id Keywords: Hydroxybenzoic Acid, Reducing Agent, Silver Nanoparticle Abstract.
This study use o-hydroxybenzoic, p-hydroxybenzoic and o,p-dihydroxybenzoic acids as reducing and stabilizing agents because its structure contains both hydroxyl group which is expected to reduce Ag+ to Ag0 and carboxylic group which is expected to stabilize the formed AgNPs.
Yellow color of the solution is formed by the structure of the nanoparticles in the samples that have specific surface plasmon resonance (SPR).

Besides the mechanical properties, the bond to substrate concrete and shrinkage behavior of the repair material are essential for application in structure rehabilitation.
It can be seen that the crystals are immense, slender, flattened and blade-like in layered structure, which is very different from those bundled needle shaped crystals shown in the previous figures.

Molecular beam epitaxy using solid source evaporation is proposed to achieve the growth of heteropolytypic structures, however many challenges are still not resolved with this technique [15].
More recently we used standard chemistry with silane and propane as precursors in a hot-wall CVD reactor [19].
In this paper only results using the standard chemistry with silane and propane as precursors are reported.

Fly ash as a useful by-product is disposed in landfills or is re-used in a building chemistry as a pozzolan material [6].
The ammonium gas formed in the alkaline slurry migrates to the forming pores and could go out easily from the hardening structure.
This means, that all the ammonium nitrogen is released during the mixing and aging phase, probably thanks to the pore structure of AAC.
