Everyone in pharmaceuticals wants a piece of the action when it comes to weight-loss drugs. In the US, manufacturers Novo Nordisk and Eli Lilly have convinced regulators that they can now supply enough of their respective injection products…

Materials

Materials for digestion protocol, pepsin from porcine gastric mucosa (> 2500 units/mg protein), pancreatin from porcine pancreas (8xUSP), porcine bile extract were purchased from Merck/Sigma-Aldrich (Merck & Co., Philadelphia, PA,…

Preparation of the SP − GPTMS composite material

The water-insoluble soy protein (SP) material without the addition of the silane coupling reagent, 3-glycidoxypropyltrimethoxysilane…

UV-Vis absorption of β-CD/VR13

The extent of interaction between the β-CD and VR13 was measured by UV-Vis absorbance values of VR 13 and β-CD/vat inclusion complex (Scheme 2) at different concentrations of β-CD. The results are shown in…

Chemistry: Using a Sturat melting point apparatus, all melting points were measured in capillary tubes and were uncorrected. Using a Bruker Tensor 37 FT-IR, Perkin-Elemer FT/IR spectrophotometer (Alexandria University), and Thermo Scientific…

Structural properties

SrZrO₃ (Orthorhombic) is Perovskite crystal passing in the orthorhombic Pnmaspace group where the Sr²⁺ is bonded in an 8-coordinate geometry to eight O²⁻ atomsto Fig. 1. Sr–O bond distanceisrange from 2.52 to 2.90 Å….

The current investigation utilized gamma radiation to synthesize hydrogels by employing a water-soluble, biodegradable polymer (CMC) in combination with the AAc monomer. AAc was specifically chosen for its carboxylic group, which makes it the…

In a paper published in PNAS, researchers at King’s College London and the…

Much of the nitrous oxide entering the atmosphere from the oceans could be formed by a previously unknown inorganic route. The mechanism, uncovered by researchers in Denmark and Spain, could explain why emissions of nitrous oxide – a powerful…
