Here we report the results of three parallel efforts: the recal0.3%. Likewise, Joe Michalsky went to the SGP site with a ibration and reanalysis of pyrano-metric data from Southern recently calibrated Eppley Normal Incidence Pyrheliometer Great Plains (SGP) to improve its accuracy, use of the (NIP) and an Eppley Precision Spectral Pyranometer (PSP). multifilter rotating shadowband radiometer (M...

This study investigated the influence of flame spheroidisation process parameters for successfully manufacturing solid (dense) and highly porous microspheres from Food Drug Administration approved bioactive 45S5 glass with addition viscosity modifiers (i.e. 2 5 mol% borax V2O5), compared against processed phosphate (termed P40). Characterisation studies performed included thermal analysis (SDT)...

Abstract Molar masses, Mark-Houwink-Sakurada (MHS) exponents, and refractive index increments (dn/dc) for three lignins were determined without derivatization by multi-detector gel permeation chromatography (GPC) in dimethylformamide (DMF) with 0.05 M lithium bromide (LiBr). The lack of effectiveness fluorescence filters on molar mass determination GPC-multi-angle laser light scattering (MALS) ...

The effective hydrodynamic radii of small uncharged molecules in dilute aqueous solution were determined using Einstein's classical theory of viscosity. The radii thus obtained are those of a hypothetical sphere whose hydrodynamic behavior is the same as that of the solute molecule plus that water of hydration which is too firmly bound to partake in the viscous shearing process. The results obt...

The 2021 Tajogaite eruption of Cumbre Vieja (La Palma, Spain) was typified by the emission low viscosity lavas that flowed at high velocities and inundated a large area. We experimentally investigated rheological evolution melt feeding through concentric cylinder viscometry to understand exceptional flowing ability these constrain its emplacement dynamics. conducted set cooling deformation expe...

A series of approximately 50:50 mol % poly(L-lactide-co-ε-caprolactone) copolymers were synthesized by bulk copolymerization of L-lactide (LL) and ε-caprolactone (CL) using stannous octoate (Sn(Oct) 2 ) and diethylene glycol (DEG) as the initiating system. The resulting P(LL-co-CL) copolymers were characterized by various analytical techniques including dilute-solution viscometry, GPC, H/C NMR ...
