Molecular Weight: The molecular weight of a molecule can be defined as the sum of the masses of the atomic mass of all the atoms present in the molecule times their stoichiometric occurrence in the molecule. The number of individual atoms (moles of atoms) present i...
Boron neutron capture therapy of brain tumors: Enhanced survival following intracarotid injection of sodium borocaptate with or without blood-brain barrier... PURPOSE: Sodium borocaptate (Na2B12H11SH or BSH) has been used clinically for boron neutron capture therapy (BNCT) of patients with primar...
The effect of low-molecular-weight salts (Na2SO4, KCl, NaF, and NaSCN) on swelling of polyelectrolyte and amphiphilic hydrogels of network paired polymers of poly-N-vinylpyrrolidone with poly-5-vinyltetrazole, polystyrene, and poly(methyl methacrylate) in aqueous media was demonstrated. It was ...
(16). High molecular weight chromosomal DNA was size-fractionated on a preparative sucrose gradient (5-20% sucrose, 20 mM Tris-HCl, pH 8.0, 20 mM Na2EDTA, pH 8.0, 0.2 M NaCl, and 0.1% Sarkosyl). Fractions were analyzed by electrophoresis on a 0.8% agarose gel; fractions with very ...
Hyper-dimensional computing (HDC) is an emerging paradigm of lightweight machine learning that leverages the orthogonality of vectors in high dimensional space coupled with simple arithmetic operations for learning that are, comparatively to SOA deep learning architectures, simple to implement in hardware...
In order to check the calibration in this low molecular-weight region and to establish an independent curve for polybutadiene, a polybutadiene sample prepared by a-methylstyrene tetramer-Na2 initiation was chromatographed. In doing this, dual detection was used, consisting of a differential ...
Highly water-soluble Na2[IrF6] was obtained by direct F2 fluorination of Na2[IrCl6] Á 6H2O at elevated temperature (200 °C) and characterized by powder X-ray diffraction18–20. Addition of a solution [(IPrPFh6]4þ2 À¼ tetraphenylphosphonium(V) cation) solution yielded (PPh4)2...
Effect of low-molecular-weight organic acids on the adsorption of fluoride on soils with variable charge低分子量有机酸对几种可变电荷土壤吸附氟的影响 The effect of four low molecular weight organic acids on the adsorption of fluoride on soils with variable charge was investigated with a batch ...
Both metals thus show innate immune response capacities, although to a lower extent than reported earlier for NiCl2, CoCl2 and Na2 [PdCl4]. Importantly, the gold-induced response could be ascribed to TLR3 rather than TLR4 triggering, whereas the nature of the innate mercury response remains to...
