Evaluation of relative beam-profile-compensated quantum yield of upconverting nanoparticles over a wide dynamic range of power densities

Autor: J. S. Matias, K. Komolibus, S. Konugolu-Venkata-Sekar, S. Andersson-Engels

Publikováno v: Nanoscale. 14(6)

The presented work uses a discrete strategy of beam profile compensation to evaluate the local internal quantum yield (iQY) of upconverting nanoparticles (UCNPs) at the pixel level of the beam profile using a compact CMOS camera. The two-photon proce

Publikováno v: Physical Review B. 96

Since the up-conversion phenomenon in rare-earths (REs) doped ${\mathrm{NaYF}}_{4}$ is strongly affected by the crystal electric field (CF), determining the CF parameters, wave functions, and scheme of the energy levels of the RE $J$ multiplets could

Transition-metal dichalcogenides (WTe$_2$ and MoTe$_2$) have drawn much attention, recently, because of the nonsaturating extremely large magnetoresistance (XMR) observed in these compounds in addition to the predictions of likely type-II Weyl semime

Extremely large magnetoresistance (XMR), observed in transition-metal dichalcogenides, ${\mathrm{WTe}}_{2}$, has attracted recently a great deal of research interest as it shows no sign of saturation up to a magnetic field as high as 60 T, in additio

Publikováno v: Soil Research. 43:297

This paper reports on the first systematic inventory of soil water repellency in Portuguese coastal dune sand areas. Since water repellency is widely associated with certain vegetation types or individual plant species, this inventory concerned arabl

The role of soil water repellency in overland flow generation in pine and eucalypt forest stands in coastal Portugal

Autor: Celeste Coelho, Richard A. Shakesby, I. M. B. Perez, M. J. S. Matias, Jan Jacob Keizer, C. S. P. Domingues, Maruxa Malvar, António J. D. Ferreira

Publikováno v: Soil Research. 43:337

Soil water repellency is now known to occur in diverse soils in various parts of the world. One of the possible adverse effects of soil water repellency is that it can reduce infiltration capacity and hence, on sloping terrain, enhance overland flow

A FIELD EXAMPLE OF THE USE OF ANISOTROPY PARAMETERS DERIVED FROM RESISTIVITY SOUNDINGS*

Autor: M. J. S. Matias, G. M. Habberjam

Publikováno v: Geophysical Prospecting. 32:725-739

In areas where steep dips are encountered conventional practice in resistivity work has involved orienting arrays favourably in relation to the geological strike. In concealed conditions, however, the geological strike may not be known; moreover, str
