Enhancing the weatherability of bamboo-based products is essential for increasing their application lifespan. In this study, a composite protective coating containing organic and inorganic UV absorbers hindered amine light stabilizer (HALS) was investigated outdoor bamboo scrimber (OBS). The optical properties weathered coated uncoated samples were by colorimetry UV-Vis spectrophotometry. Fouri...

Following previous studies with a DOTA-like bifunctional chelator (H(3)L1) containing an ethylenic linker between the macrocycle backbone and a quinazoline pharmacophore, we synthesized and fully characterized a congener macrocyclic ligand (H(3)L2) having a longer, five-carbon spacer for the linkage of the quinazoline moiety. Both H(3)L1 and H(3)L2 were used to prepare indium(III) complexes aim...

Ground spices are food ingredients that can enrich the taste, aroma and taste of dishes have a very limited service life. Many manufacturers use formalin as preservative to overcome short shelf life ground spices. Formalin is clear, colorless or almost liquid with pungent odor. The prohibited in Regulation, because formaldehyde toxic (poisonous). This study identified content instant market Mal...

Nebistar-SA is available for the treatment of stage II hypertension. It contains nebivolol (NV; 5 mg) and amlodipine (AM; 2.5 mg). In the present study, simple, rapid, precise and accurate method for the simultaneous estimation of these drugs have been developed and validated by UV spectrophotometry. The method was validated with respect to its linearity, limit of quantitation (LOQ), limit of d...
