Impact of noise barriers on the dispersal of solid pollutants from car emissions and their deposition in soil

open access: yesSoil Science Annual, 2017
Despite the existence of various methods aimed at protecting the environment from the negative influence of roads, there is a lack of adequate techniques for monitoring and reducing the spread of roadside pollution into the air and soils. The aim of this

Determination of Platinum Group Elements (PGE) in Soil and Grass Using ICP-MS in UKM Engineering Lake [PDF]

open access: yes, 2014
Three elements in platinum group elements (PGE) which are platinum (Pt), palladium (Pd) and rhodium (Rh) are widely used in vehicle exhaust as catalyst in changing material and toxic gases such as CO, HC and NOx.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Electrocatalysis in Solid Acid Fuel Cells [PDF]

open access: yes, 2011
Solid state electrochemical reactions play a crucial role in many energy conversion devices, yet the pathways of many reactions remain unknown. The elusiveness of the reaction mechanisms is due, in part, to the complexity of electrochemical reactions ...

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

open access: yesMolecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

The podiform chromitites in the Dagküplü and Kavad mines, Eskisehir ophiolite (NW-Turkey): Genetic implications of mineralogical and geochemical data

open access: yesGeologica Acta, 2009
Mantle tectonites from Eskisehir (NW-Turkey) include high-Cr chromitites with limited variation of Cr#, ranging from 65 to 82. Mg# ratios are between 54 and 72 and chromite grains contain up to 3.71 wt% Fe2O3 and 0.30 wt% TiO2.

Basic Study on Distribution Behavior of Platinum Group Ions Using TPPS-[Cnmim][Tf2N] in Hydrochloric Acid Medium

open access: yesJournal of MMIJ, 2017
Although solvent extraction has been used in the recovery of rare metals from urban mines, some challenges remain. For example, large amounts of organic solvent are required for Pd (II) separation owing to the slow extraction kinetics of dihexylsulfide ...

Major, trace and platinum-group element geochemistry of harzburgites and chromitites from Fuchuan, China, and its geological significance

open access: yesOpen Geosciences, 2022
The Fuchuan peridotites have dual features of mid-ocean ridge basalt and supra-subducted zone peridotites and have been experienced high degrees of partial melting; chondrite-normalized “U”-shaped rare earth element (REE) patterns of Fuchuan harzburgites

Simultaneous dual-element analyses of refractory metals in naturally occurring matrices using resonance ionization of sputtered atoms [PDF]

open access: yes, 1995
The combination of secondary neutral mass spectrometry (SNMS) and resonance ionization spectroscopy (RIS) has been shown to be a powerful tool for the detection of low levels of elemental impurities in solids.
