Near-infrared spectroscopic applications in pharmaceutical particle technology
(Taylor & Francis, 2019-07-17)
Near-infrared spectroscopy (NIRS) is nowadays an established analytical technique in the pharmaceutical industry. The aim of this review is to present the progress of NIRS in providing useful information for pharmaceutical ...
Infrared Spectroscopic Study of the Carbon Dioxide Adsorption on the Surface of Cerium-Gallium Mixed Oxides
(Elsevier Science, 2012-01)
In order to modified the acid-base properties of pure cerium dioxide, a series of ceria-based oxides doped with gallium(III) cations (from 5 to 50% mol/mol of Ga) was prepared by co-precipitation in basic aqueous solution ...
Exploratory monitoring of the quality and authenticity of commercial honey in Ecuador
(Multidisciplinary Digital Publishing Institute, 2019-03-20)
Honey is one of the oldest sweetening foods and has economic importance, making this product attractive to adulteration with cheap sugars. This can cause a critical problem in the honey industry and a possible health risk. ...
Detection of durum wheat pasta adulteration with common wheat by infrared spectroscopy and chemometrics: A case study
(Elsevier Science, 2020-04-09)
Fourier transform (FT) infrared spectroscopy, in combination with Partial-Least Squares Discriminant Analysis (PLS-DA) and Linear Discriminant Analysis (LDA), was used to discriminate commercial durum wheat pasta from Italy ...
Changes in the crystalline degree in neutron irradiated EPDM viewed through infrared spectroscopy and inelastic neutron scattering
(Universidade Federal do Rio de Janeiro, 2018-07)
The changes in the degree of crystallinity in commercial Ethylene Propylene Diene rubber-type M (EPDM) irradiated with neutrons at different doses has been studied by means of inelastic neutron scattering and infrared ...
Experimental study of tautomeric equilibria of 2-cyanobenzoic acids in gas, solution and solid phase
(Lifescience Global, 2012-12)
2-cyanobenzoic acids are very important compounds in several sciences, and it is because of this that studying their tautomeric equilibria is of great interest. Ring-chain tautomeric equilibria of 2-, 3- and 4- cyanobenzoic, ...
External cavity-quantum cascade laser (EC-QCL) spectroscopy for protein analysis in bovine milk
(Elsevier Science, 2017-04)
The analytical determination of bovine milk proteins is important in food and non-food industrial applications and yet, rather labour-intensive wet-chemical, low-throughput methods have been employed since decades. This ...
Effect of 25-hydroxycholesterol in viral membrane fusion: Insights on HIV inhibition
(Elsevier Science, 2018-05)
Recently, it was demonstrated that 25-hydroxycholesterol (25HC), an oxidized cholesterol derivative, inhibits human immunodeficiency virus type 1 (HIV) entry into its target cells. However, the mechanisms involved in this ...
Spectroelectrochemical studies of poly(N-methylaniline) formation, redox behaviour and degradation. A comparison with polyaniline
(Pergamon-Elsevier Science Ltd., 2014-03)
Spectroelectrochemical methods, in-situ Fourier Transform Infrared (FTIR) and Differential Electrochemical Mass Spectroscopy (DEMS), are used to study the formation of poly(N-methylaniline) (PNMANI) by anodic oxidation of ...
