Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT For the first time, a mixture of cardanol and cardol esters has been studied as plasticizers for PVC. From our previous work, it has been established that the favorable plasticizing properties of cardol for PVC materials exist. Hence, the utilization of cashew nutshell liquid (CNSL), a naturally occurring mixture of cardanol and cardol, as a ...

Molecular Signatures in the Near Infrared Dayside Spectrum of HD 189733b [PDF]
, 2008 We have measured the dayside spectrum of HD 189733b between 1.5 and 2.5 microns using the NICMOS instrument on the Hubble Space Telescope. The emergent spectrum contains significant modulation, which we attribute to the presence of molecular bands seen ...

The quantitative analysis of polyvinylpyrrolidone by infrared spectrophotometry
Journal of Pharmacy and Pharmacology, 1971 Abstract The quantitative assay of the binding agent polyvinylpyrrolidone (PVP) in granules of magnesium carbonate has been shown to be possible. The method is to determine the infrared absorption spectrum of a chloroform extract. Quantities of PVP down to 0·1 mg can be successfully assayed to ±1 % in solution as dilute as 0·1 % w/v.

Enhanced Photoelectrochemical Water Splitting Using Bismuth/Bismuth Selenide Nanocomposites
Chemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.Bismuth/Bismuth Selenide (Bi/Bi₂Se₃) nanocomposites exhibit enhanced photoelectrochemical (PEC) water splitting performance due to optimized energy band alignment and efficient charge separation. The figure illustrates the impact of synthesis temperature on bandgap tuning, leading to improved photocatalytic activity and hydrogen evolution.

Infrared photometry and spectrophotometry of Titan [PDF]
The wide variation in infrared brightness temperature of Titan is explained in terms of a greenhouse effect. Radiometric observations in the infrared and microwave frequencies indicate an alternate hot atmospheric model. Methane, ammonia, hydrogen atoms,

Pine bio‐oil based biorefinery procedure for the production of antioxidants, acids, and sugars
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract In this study, a wood‐based biorefinery with Pinus halepensis biomass was developed to obtain acids, sugars, and antioxidants with high recovery yields. Pine wood residues from sustainable forest management are transformed into bio‐oil (BO) and separated into value‐added chemicals with an integrated and innovative methodology.

Progress towards a universal family of UV-IR extinction laws [PDF]
arXiv, 2016 We present our progress on the study of extinction laws along three diferent lines. [a] We compare how well different families of extinction laws fit existing photometric data for Galactic sightlines and we find that the Ma\'iz Apell\'aniz et al. (2014) family provides better results than those of Cardelli et al. (1989) or Fitzpatrick (1999).

An Integrated Spectrophotometric Survey of Nearby Star-Forming Galaxies [PDF]
, 2005 We present integrated optical spectrophotometry for a sample of 417 nearby galaxies. Our observations consist of spatially integrated, S/N=10-100 spectroscopy between 3600 and 6900 Angstroms at ~8 Angstroms FWHM resolution. In addition, we present nuclear (2.5"x2.5") spectroscopy for 153 of these objects.
