Current bioavailability models, such as the free ion activity model and biotic ligand model, explicitly consider that metal exposure will be mainly to the dissolved metal in ionic form. With the rise of nanotechnology products and the increasing release of metal‐based nanoparticles (NPs) to the environment, such models may increasingly be applied to support risk assessment. However, it is not ...

These are 3 ideas that may lead to the root cause. 3% is not an acceptable scrap rate as some parts may have only a 5% profit margin. I wish you well. I believe the dye is added and I am finding out exactly how. No regrind is permitted. The carrier material and colorant is specifically intended for LDPE, but I am confirming this. LDPE was chosen for its flexibility because it ...

Large resort hotel with highly variable levels of business due to seasonality. Garbage compactor was on a regular service schedule, twice per week. Compactor often was not full when picked up by hauler. Seasonal variations meant large variation in waste volumes generated. Engineering staff had no accurate method to measure compactor fill level. The ...

The effect of nitrogen plasma immersion ion implantation (PIII) treatment on the thin films of gadolinium oxide (GdxOy) for use in resistive random access memory (RRAM) applications is reported. From the X–ray photoelectron spectroscopic analysis, the formation of Gd–N bond was evidenced by a shift in the peak Gd 4d peaks towards lower ...

Dialdehyde 8-aminoquinoline starch (DASQA) was synthesized by the reaction of dialdehyde starch (DAS) and 8-aminoquinoline and was used to adsorb various ions from aqueous solution. DASQA was characterized by Fourier transform infrared (FT-IR) spectra, thermogravimetric analysis, X-ray diffraction analysis. The adsorption properties of the polymer for Pb2+, Cu2+, ...

This paper reports the effect of various process parameters on the removal of chromium from aqueous solution using formaldehyde–treated timber industry waste (sawdust). The adsorbent was characterised by Scanning Electron Microscopy (SEM) and Energy Dispersive X–Ray Analysis (EDAX). Influence of chromium concentration, pH, adsorbent dose and contact time on chromium removal from aqueous solution ...

This paper communicates the distribution of carbon atoms in a single poly-cyclic aromatic (PCA) layer (graphene) in Tikak coal from Assam, India. The pair distribution function (PDF) analysis performed indicates no evidence of any graphite like structure in this coal. The aromatic fraction is observed to be 74% with the aliphatic fraction correspondingly estimated to be 26% in this coal. The ...

Spent grain, the low-cost and abundant biomass produced in the brewing industry, was functionalized with thiol groups to be used as an adsorbent for Hg(II) removal from acidic aqueous solution. The adsorbents were characterized by the energy-dispersive X-ray analysis (EDAX) and Fourier transform infrared (FTIR) spectroscopy. Optimum pH for Hg(II) adsorption onto the thiol-functionalized spent ...

The aim of this study is to investigate the conditions for the removal of manganese ions from synthetic groundwater by oxidation using KMnO4 to keep the concentration below the allowed level (0.05 mg/L). The process includes low-level aeration and addition of KMnO4 in a Jar test system with Mn2 +  concentration of 0.50 mg/L, similar to that of natural groundwater in Taiwan. Different parameters ...

Ruthenium nanoparticles stabilised by polyaromatic amine-containing compounds (aminoethylcarbazole, aminoanthracene and aminoanthraquinone) were synthesised in solution using three different preparative methods, namely modified polyol reduction, borohydride reduction and phase-transfer method, respectively. Their product yields, particle sizes and size distributions were compared accordingly. The ...

Graphite plates were Ar+ ion-irradiated with and without a simultaneous Fe supply at room temperature. The surfaces ion-irradiated without an Fe supply were covered with densely distributed conical projections with a carbon nanofibre (CNF) on the top. The CNFs thus grown were 20-50 nm in diameter and 0.3-2 µm in length. By contrast, the graphite surfaces ion-bombarded with a simultaneous Fe ...

LTV Steel's Use of Essential EH&S Enables Environmental Pros To Do Much More Than Just Crunch Numbers The Challenge: LTV Steel's (now Mittal Steel) internal Environmental, Health & Safety (EH&S) solutions were adequate to do the job they were being called upon to do, but it was clear they would soon be outdated. The solutions resided on a mainframe and data had to be manually keyed in ...

We are now developing a system which allows the visualization of the structure and tissue associated with breast cancer, which is difficult to achieve with conventional mammography, by utilizing X-ray refraction. This system is expected to achieve an approximately 1000-fold higher contrast and high spatial resolution at low dose; compared to techniques by use of X-ray absorption. Monochromatic ...

X-ray diffraction techniques have been extensively employed to study several structural and chemical properties of self-assembled islands. In this review we discuss recent results on Ge islands grown on Si(001). Grazing incidence diffraction is used to map the strain distribution of Ge pyramids and domes. By tuning the X-ray energy near the Ge K edge – to perform anomalous diffraction ...
