Materials for Clean H² Production from Bioethanol Reforming

Hydrogen is one of the most important resources in providing food, fuel, and chemical products for our everyday life. Sustainable catalytic hydrogen production from bioethanol has gained significant attention in recent years due to globally diminishing fossil fuel supplies, which

Peptide Stability and Potential Degradation Pathways

To prevent or minimize peptide degradation we recommend storing the peptide in lyophilized form at –20 °C or –80 °C. Once in solution, the peptide/protein should be stored frozen in individual aliquots to avoid freeze-thaw cycles. Also, prolonged exposure to

Reducing Organic Photoredox Catalysts for Visible Light-Driven Polymer and Small Molecule Synthesis

Photoredox catalysis is a powerful synthetic methodology to form challenging covalent bonds using light irradiation. It is effective for light-driven polymer and small molecule synthesis.

Antifoams

Antifoams are supplied as two basic types of composition or mixtures of the two. Organic antifoams are of synthetic origin. Silicone-based antifoams are generally considered to be siloxane polymers and are also synthetic.
