Structures, enthalpies of formation, and ionization energies for the parent and binary mixed carbon, silicon, nitrogen, and phosphorus cubane derivatives: A G4MP2 theoretical study [PDF]

open access: yes, 2010
Gas phase standard state (298.15 K, 1 atm) structures, enthalpies of formation, and ionization energies (IEs) were calculated at the G4MP2 composite method level of theory for the parent and binary mixed carbon, silicon, nitrogen, and phosphorus cubane ...

Donor behavior in indium-alloyed silicon [PDF]

open access: yes, 1970
The anomalous doping behavior of Si regrown from In solution was studied by (1) Schottky barrier evaluation of conductivity type, (2) electron microprobe analysis for phosphorus, and (3) channeling effect measurements for interstitial In.

Two-Dimensional Dirac Fermions Protected by Space-Time Inversion Symmetry in Black Phosphorus [PDF]

open access: yes, 2017
We report the realization of novel symmetry-protected Dirac fermions in a surface-doped two-dimensional (2D) semiconductor, black phosphorus. The widely tunable band gap of black phosphorus by the surface Stark effect is employed to achieve a ...

The effect of phosphorus on the iron redox ratio, viscosity, and density of an evolved ferro-basalt [PDF]

open access: yes, 1994
Despite the abundant evidence for the enrichment of phosphorus during the petrogenesis of natural ferro-basalts, the effect of phosphorus on the physical properties of these melts is poorly understood.

Single‐cell/nanoparticle trajectories reveal two‐tier Lévy‐like interactions across bacterial swarms

open access: yesView, 2022
Swarming bacteria can organize themselves into different local communities, ranging from active cell rafts to reticular biofilms. How millions of motile and immotile cells are dynamically linked together and still function as a whole is a critical ...

Effect of influent nutrient ratios and hydraulic retention time (HRT) on simultaneous phosphorus and nitrogen removal in a two-sludge sequencing batch reactor process [PDF]

open access: yes, 2009
A laboratory-scale anaerobic–anoxic/nitrification sequencing batch reactor (A2N- SBR) fed with domestic wastewater was operated to examine the effect of varying ratios of influent COD/P, COD/TN and TN/P on the nutrient removal.
