Use of lignin extracted from different plant sources as standards in the spectrophotometric acetyl bromide lignin method
(Amer Chemical Soc, 2011)
A nongravimetric acetyl bromide lignin (ABL) method was evaluated to quantify lignin concentration in a variety of plant materials. The traditional approach to lignin quantification required extraction of lignin with acidic ...
Variation in canopy structure, leaf area, light interception and light use efficiency among Eucalyptus clones
(2020-05-01)
Differences in growth rates between Eucalyptus clones depend on differences in the acquisition of resources, and the efficiency of using resources to produce carbohydrates and grow wood. We examined differences in canopy ...

This study was aimed at assessing the genetic diversity in herds of Marota goats and examine the impact of molecular markers in the genetic management of conservation herds. Seventy-six animals of one conservation heard ...
Size-dependent SERS enhancement of colloidal silver nanoplates: the case of 2-amino-5-nitropyridine
(John Wiley & Sons LtdChichesterInglaterra, 2009)
Influence of size-corrected bound-electron contribution on nanometric silver dielectric function. Sizing through optical extinction spectroscopy
(Iop Publishing, 2013-09)
The study of metal nanoparticles (NPs) is of great interest due to their ability to enhance optical fields on the nanometric scale, which makes them interesting for various applications in several fields of science and ...
Photometry at Cerro Tololo, Chile: effects of mount agung eruption
(1965)
Extinction effects of the volcanic dust injected into the stratosphere by the violent eruption of Mount Agung, Bali, 17 March 1963, were studied. Visual extinction coefficients were measured photoelectrically for 153 nights ...
