Description

Application

Synthesis of lactose-based surfactants: Research by Enayati, Gong, and Abbaspourrad demonstrated the use of d-Lactose monohydrate in the synthesis of lactose lauryl ester, employing aluminosilicate zeolite as a catalyst. This study presents a method for producing non-ionic surfactants, highlighting d-Lactose monohydrate′s role in industrial and pharmaceutical applications (Enayati et al., 2019).

Hiding a realistic object using a broadband terahertz invisibility cloak.

Fan Zhou et al.

Scientific reports, 1, 78-78 (2012-02-23)

The invisibility cloak has been a long-standing dream for many researchers over the decades. Using transformation optics, a three-dimensional (3D) object is perceived as having a reduced number of dimensions, making it "undetectable" judging from the scattered field12345. Despite successful

Evaluation of Lactococcus lactis Isolates from Nondairy Sources with Potential Dairy Applications Reveals Extensive Phenotype-Genotype Disparity and Implications for a Revised Species.

Daniel Cavanagh et al.

Applied and environmental microbiology, 81(12), 3961-3972 (2015-04-05)

Lactococcus lactis is predominantly associated with dairy fermentations, but evidence suggests that the domesticated organism originated from a plant niche. L. lactis possesses an unusual taxonomic structure whereby strain phenotypes and genotypes often do not correlate, which in turn has

Chemometric methods for the quantification of crystalline tacrolimus in solid dispersion by powder X-ray diffractrometry.

Akhtar Siddiqui et al.

Journal of pharmaceutical sciences, 103(9), 2819-2828 (2014-03-04)

The objective of this study was to develop powder X-ray diffraction (XRPD) chemometric model for quantifying crystalline tacrolimus from solid dispersion (SD). Three SDs (amorphous tacrolimus component) with varying drug to excipient ratios (24.4%, 6.7%, and 4.3% drug) were prepared.
