Spin-1/2 chains with alternating antiferromagnetic (AF) and ferromagnetic (FM) couplings exhibit quantum entanglement like the integer-spin Haldane chains and might be similarly utilized for quantum ...

A new method to capture carbon dioxide from the air has been developed at the University of Helsinki's chemistry department. The ease of releasing CO 2 is the key advantage of the new compound. In ...

Abstract: Shear-wave elasticity imaging (SWEI) enables the quantitative assessment of the mechanical properties of tissue. In SWEI, the effective generation of acoustic radiation force is of paramount ...

A Palestinian woman in Gaza has died as a winter storm threatens the lives of nearly 900,000 Palestinians living in tents across the devastated coastal enclave. The 30-year-old, identified as Alaa ...

UBC Okanagan researchers have uncovered how plants create mitraphylline, a rare natural compound linked to anti-cancer effects. By identifying two key enzymes that shape and twist molecules into their ...

The Knoevenagel and Biginelli reactions are very important protocols for organic chemistry. The Knoevenagel condensation is a type of aldol reaction widely used in the construction of new C–C bonds.
