Effect of Na–Sn Flux on the Growth of Type I Na8Si46 Clathrate Crystals
Crystals, 2022 In the crystal growth of Na–Si clathrate (type I, Na8Si46) during Na evaporation from a Na–Si–Sn solution at 723 K, the composition of a Na–Sn flux in the starting material strongly influences the morphology and size of the formed clathrate crystals.

Impact of the motor magnetic model on direct flux vector control of interior PM motors [PDF]
, 2011 The stator-field-oriented, direct-flux vector control has been proven to be effective in terms of linear torque control and model independent performance at limited voltage and current (i.e. in flux weakening) for AC drives of various types.

The global carbon dioxide flux in soil respiration and its relationship to vegetation and climate
, 1992 We review measured rates of soil respiration from terrestrial and wetland ecosystems to define the annual global CO 2 flux from soils, to identify uncertainties in the global flux estimate, and to investigate the influences of temperature, precipitation,

Chloroquine inhibits autophagic flux by decreasing autophagosome-lysosome fusion
Autophagy, 2018 Macroautophagy/autophagy is a conserved transport pathway where targeted structures are sequestered by phagophores, which mature into autophagosomes, and then delivered into lysosomes for degradation.

Distributions of critical flux: modelling, experimental analysis and consequences for cross-flow membrane filtration [PDF]
, 2005 This paper discusses the distribution of critical flux (DCF) in cross flow filtration. These distributions are described here by a normal function with a mean critical flux and its standard deviation.
