Abstract Biosynthesis of tin oxide nanoparticles (SnO 2 NPs) was cost-effectively carried out in non-toxic aqueous mixture Aquilaria malaccensis (agarwood) leaves extract and (IV) chloride pentahydrate solution at room temperature. The synthesized SnO NPs were characterized by using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field emission scanning electron micros...

Komposit serat alam adalah material yang sangat baik karena ringan, kuat, murah, mudah di bentuk dan ramah lingkungan. Pohon gaharu (Aquilaria malaccensis) menghasilkan resin berbau harum untuk pembuatan parfum. Selain juga halus bisa dijadikan penguat komposit. Tujuan penelitian mendapatkan efek perendaman kulit terhadap pengujian mekanik menggunakan matriks polyester BQTN 157 sebagai apakah k...

The genus Cyperus belongs to tribe Cypereae, subfamily Cyperoideae and family Cyperaceae that is the largest genus in this family after Carex. The classification of genus Cyperus is still unsettled because of morphological variations and therefore, makes determination of subgenera boundaries and species difficult. In Flora Iranica (KUKKONEN 1998) this genus was divided to six subgenera. In this...

The genus Cyperus with five subgenus and 29 species, is the second largest genus of Cyperaceae family in flora of Iran. In this research, stem and leaf anatomy of 10 species belonging to subgenus Cyperus is investigated. The stems in transverse section of all examined species were triangular except for C. bulbosus which was subterete to polygonal. The ground tissue was spongy with numerous and ...
