ARE CHEMICAL ENTITIES REAL?

Redazione
(AGENPARL) – CAMBRIDGE (UNITED KINGDOM), sab 07 novembre 2020 Talking of atoms, molecules, bonds and reactions is so essential to chemistry’s practice that questioning their existence might seem a strange thing to do. However, it is an open question in philosophy whether this chemical ‘stuff’ actually exists; a question that......

PORPHYRIN ASSEMBLY IS ‘LARGEST PURE ORGANIC SYNTHETIC CAGE’ EVER MADE

Redazione
(AGENPARL) – CAMBRIDGE (UNITED KINGDOM), gio 05 novembre 2020 Researchers in South Korea have created what they claim is the ‘largest void containing pure organic cage’ molecule ever reported. The ‘gigantic’ spherical structures are made from porphyrins and linker molecules and self-assemble in a simple template-free process. In nature, large......

SMART BOTTLE BRUSHES

Redazione
(AGENPARL) – MüNCHEN (BAYERN), ven 30 ottobre 2020 They look like microscopic bottle brushes: Polymers with a backbone and tufts of side arms. This molecular design gives them unusual abilities: For example, they can bind active agents and release them again when the temperature changes. With the help of neutrons,......

HIGHLY SELECTIVE MEMBRANES

Redazione
(AGENPARL) – WORCESTER (MASSACHUSETTS), mer 21 ottobre 2020 (University of Tokyo) Membranes with microscopic pores are useful for water filtration. The effect of pore size on water filtration is well-understood, as is the role of ions, charged atoms, that interact with the membrane. For the first time, researchers have successfully......
