In this study new 2-(4-methyl-phenoxymethyl)benzoyl thioureas, N-[(R-amino)thioxomethyl]-2-[(4methylphenoxy)methyl]benzamides, were synthesized by the reaction of 2-(4-methyl-phenoxymethyl)benzoyl isothiocyanate with different amines. Structures of the new compounds were identified by spectroscopic technique and also confirmed by elemental analysis. The compounds will be screened for their in v...

One new compound named amauroamoienin (1), together with thirteen known compounds (2-14), was isolated from the EtOAc extract of Amauroderma amoiensis. The structures of these compounds were elucidated by the analysis of 1D and 2D spectroscopic data and the MS technique. The bioassays of inhibitory activities of these isolates against acetylcholinesterase were evaluated, and compounds 1, 3, and...

We use N-body/photometric galaxy simulations to examine the impact of sample variance of spectroscopic redshift samples on the accuracy of photometric redshift (photo-z) determination and calibration of photo-z errors. We estimate the biases in the cosmological parameter constraints from weak lensing and derive requirements on the spectroscopic follow-up for three different photo-z algorithms c...

Spectroscopy has shown to be of value in determining benign from malignant tissue. Incorporation of spectroscopic measurements may increase the diagnostic yield of transthoracic needle biopsies. Given the increasing amount of incidentally found lung lesions, such a technique may prevent unnecessary invasive procedures and uncertainty for the patient.

Titanium gels doped with water-soluble cationic porphyrin were synthesized by the sol–gel polymerization of Ti (OC4H9)4. In this work we investigate the spectroscopic properties along with SEM images of tetra carboxyl phenyl porphyrin when incorporated into porous matrix produced by the sol–gel technique. Keywords—TCPP; Titanium matrix; UV/Vis spectroscopy; SEM.

Glaucoma is a chronic neurodegenerative disease characterized by apoptosis of retinal ganglion cells and subsequent loss of visual function. Early detection of glaucoma is critical for the prevention of permanent structural damage and irreversible vision loss. Raman spectroscopy is a technique that provides rapid biochemical characterization of tissues in a nondestructive and noninvasive fashio...
