Peristaltic pumps enable precise liquid filling and transfer. By squeezing flexible tubing, they move fluids while keeping the liquid isolated from the pump mechanism.

Widely used in laboratories, pharmaceuticals, chemical dosing and biotech.

Xia-Heng Zhang’s team uncovered a new role for N-nitrosamines in aromatic amine functionalisation.

Nitric acid-mediated N₂O extrusion converts aromatic C–N bonds into C–Cl, C–Br, C–I and C–C bonds, providing a versatile route to diversify aromatic molecules.

3D-printed metal “forest” 🌲

It looks almost like a tiny city of metal, but every pore and layer has a purpose.

These lattice structures can offer high surface area, low weight, and efficient heat transfer—showing what metal 3D printing can really do.
