The uptake of the nuclear waste product technetium-99 was studied in common duckweed (Lemna minor). In addition to measurements, a model involving two compartments in duckweed with different chemical forms of technetium was derived. The model was tested by chemical speciation, i.e. differentiating between reduced Tc-compounds and Tc(VII)O(4)(-). The TcO(4)(-) concentrations measured were in goo...

06 Transparent conductive oxides (TCOs) are a technologically important class of materials. [ 1 ] Herein we describe a facile, universal, and green ‘one-pot’ approach to produce stable dispersions comprising TCO nanoparticles (NPs) such as SnO 2 , In 2 O 3 , ATO ( ≡ SnO 2 :Sb), ITO ( ≡ In 2 O 3 :Sn), and ZTO ( ≡ SnO 2 :Zn). The synthesis begins by etching the bare metal powder precursors (Sn, I...

BACKGROUND Hemodialysis patients are treated with bicarbonate dialysate to correct the metabolic acidosis, which results from the metabolism of dietary and endogenous protein. The concentration of plasma tCO(2) is used to gauge the success of therapy. Reported low values in pre-dialysis blood suggest incomplete correction of acidosis in a substantial percent of the dialysis population. However,...

The counter electrode (CE) containing catalyst layer and transparent conducting oxide (TCO) is by far the most expensive components in Dye sensitized solar cells (DSSC) due to use of rare earth element such as Pt. potential replacement both TCO Pt-based would essentially pave way mass commercialization technology DSSC. In this investigation, an attempt has been made replace Pt with a single del...

Continuous cover forestry (CCF) has proven to financially outperform rotation (RF) with low or even moderate social price of carbon in mineral soils. However, date there are no studies compare financial performance joint production (timber and sequestration) between soils peatlands when CCF is applied. A vast variety harvest intervals intensity (expressed as post-harvest basal area) for a matur...

Dye-sensitized solar cells (DSSCs) have emerged as a high-efficiency, low-cost alternative to solid-state silicon solar cells. Typically, DSSCs are composed of a mesoporous titania nanocrystal electrode on a transparent conductive oxide (TCO) substrate with ruthenium-based sensitizers on the titania nanocrystals, platinum on the TCO substrate as a counter electrode, and iodine/iodide electrolyt...

Thin-film photovoltaic (PV) modules often suffer from a variety of parasitic resistive losses in transparent conductive oxide (TCO) and absorber layers that significantly affect the module electrical performance. This paper presents the holistic investigation of resistive effects due to TCO lateral sheet resistance and shunts in amorphous-silicon (a-Si) thin-film PV modules by simultaneous use ...

The radiobiocomplexes labeled with technetium-99m (Tc-99m) have been widely used in nuclear medicine in single photon emission computed tomography and in basic research. The aim of this study was to assess the influence of a Nectandra membranacea extract on the bioavailability of the sodium pertechnetate (Na(99m)TcO(4)) radiobiocomplex in rat organs. The animals were treated with a N. membranac...

BACKGROUND Familial non-medullary thyroid cancer (fNMTC) is a complex genetic disorder that is more aggressive than its sporadic counterpart. Thus far, three genetic loci have been implicated in susceptibility to fNMTC by linkage analysis. METHODS We used linkage analysis to test the significance of two of the known susceptibility loci for fNMTC, TCO on 19p13 and NMTC1 on 2q21 in 10 fNMTC fam...

PURPOSE The purpose of this noninvasive pilot study was to examine the changes in transcutaneous oxygen (tcO2), skin temperature, and hyperemic response in the heels, sacrum, and trochanters in a 2-hour loading-unloading condition in nursing home residents who are positioned in supine and lateral positions. DESIGN A 1-group, prospective, repeated-measures design was used. SUBJECTS AND SETTI...
