Digital labour shortage: a new divide in library and information studies education?
Published 2011“…A tightening of the search examined evidence of critical teaching and learning of digital labour that allow for determinations of how the digital work environment relates to library labour rights and movements. This resulted in a scan of English language and translated information for a total of 121 individual LIS programs. …”

3D-printed Franz cells - update on optimization of manufacture and evaluation
Published 2020“…The surface morphology of AM printouts was analysed before and after compatibility studies using scanning electron microscopy (SEM). Comparative permeation studies in both glass and AM Franz type diffusion cells were conducted using a caffeine solution (1.5 mg mL‑1), applied to a model silicone membrane. …”

Applying liquisolid technique to enhance curcumin solubility: a central composite design study
Published 2024“…Experimental results confirmed the formulation’s effectiveness, with a marked reduction in the time to dissolve 63.2% of the drug to 165 min, compared to 300 min for conventional formulations. Differential scanning calorimetry and Fourier-transform infrared spectra indicated a transformation of curcumin into a non-crystalline state and the formation of hydrogen bonds with Tween 80, contributing to enhanced solubility. …”

The effect of manufacturing method: direct compression, hot-melt extrusion, and 3D printing on polymer stability and drug release from polyethylene oxide tablets
Published 2024“…Tablets were manufactured by direct compression, compression of hot-melt extrudates, HME, (at 150 oC), or by FDM 3D-printing FDM (at 220 oC). Differential scanning calorimetry (DSC), X-ray powder diffraction (XRPD), gel permeation chromatography (GPC), and dissolution tests and their kinetics studies were carried out. …”
