The molecular weight (MW) is the total atomic weight of a molecule. The MW is determined by summing the mass of all of the individual atoms in a molecule. The molecular weight of a polymer is directly ...

In this review, the development of low-molecular-weight gelators and polymer-based gelators is described. The driving forces for physical gelation are non-covalent bonds, such as hydrogen bonds, ...

Nuclear Magnetic Resonance (NMR) spectroscopy has long been an indispensable tool for the characterisation of molecular structures and dynamics, offering rich insights into chemical environments, ...

Static light scattering (SLS) is a non-invasive technique used for characterizing macromolecules in solution. A beam of monochromatic light is directed through a sample and the intensity of the light ...

Mass spectrometry (MS) has long been an indispensable component in a chemist’s toolkit for both identifying and quantifying molecules within a sample. But using mass spec as an imaging technique ...

Scientists have refined a technique called mass spectrometry imaging (MSI) that translates reams of data into detailed visuals of the molecular makeup of biological samples. Their work features images ...

Credit: Grainger Films Bodies decompose differently in mass graves than in individual graves. To understand these differences ...

Compressor speed as a function of molecular weight, while maintaining the same suction and discharge pressure and mass flow rate. Polytropic head and efficiencies as a function of gas molecular weight ...

Patients with cancer have a substantial risk of recurrent thrombosis despite the use of oral anticoagulant therapy. We compared the efficacy of a low-molecular-weight heparin with that of an oral ...

Bleeding in low-molecular-weight heparin (LMWH) overdose is unpredictable and may develop insidiously in deep tissues such as retroperitoneal and intramuscular spaces. Protamine sulfate partially ...
