Organic Polymer Dots as Photocatalysts for Visible Light-Driven Hydrogen Generation

Organic Polymer Dots as Photocatalysts for Visible Light‐Driven Hydrogen Generation

Organic polymer dots were used as a photocatalyst for visible-light-driven hydrogen generation for the first time and showed impressive activity with an initial hydrogen generation rate of 8.3 mmol h−1 g−1 without the assistance of any co-catalysts. Do=donor.

Insulin resistance is a forerunner state of ischaemic cardiovascular disease and type 2 diabetes. Here we show how the human gut microbiome impacts the serum metabolome and associates with insulin resistance in 277 non-diabetic Danish individuals. The serum metabolome of insulin-resistant individuals is characterized by

Self-assembling hydrogel scaffolds for photocatalytic hydrogen production

Self-assembled ribbons of perylene amphiphiles have been shown to crystallize in the presence of a nickel-based hydrogen production catalyst, allowing efficient electronic coupling between the perylene chromophores. This hydrogel material photocatalyses the production of H2, and can be shaped and placed on surfaces for incorporation into devices.
