This article is the result of studies rheological properties and reactivity acid solutions technical lignosulfonate, decationized lignosulfonic acid, hydrochloric with addition lignosulfonate. Compositions that include lignosulfonate can be used as displacement agents in development watered layers inhomogeneous reservoir properties. The use thickening additives solves several problems. Slowing ...

An important factor in the development of sodium-ion batteries (SIBs) is use cheap and sustainable materials. Sodium lignosulfonate, a lignin derivative, demonstrated here as an attractive, “green”, water-soluble, potentially cost-effective binder for hard carbon anodes SIBs. A comparison its battery cycling performance made against other binders including sodium carboxymethyl cellulose lignin,...

As a main part of hydraulic cylinder, the piston rod is used in tough surrounding and corrosive condition; consequently a high quality protecting layer is essential. Currently EHC, electroplating hard chromium (hard chrome) is a widespread method for piston rod due to powerful performance and low cost. Unfortunately the plating process contains hexavalent chromium (Cr) which is toxic and carcin...

A study on the polyvinylidene fluoride (PVDF) membrane using lignin and lignosulfonate oil palm empty fruit bunch (OPEFB) fillers have been carried out. This aims to determine additional effect of PVDF membrane. Lignin sulfonation has a good result proven by Fourier transform infrared spectra with peak at 1192 cm−1 which indicates sulfonate group. The degree was increased 8.9% for lignosulfonat...

In this report, we show how to use the Simple Fluent Calculus (SFC) to specify generic tracers, i.e. tracers which produce a generic trace. A generic trace is a trace which can be produced by different implementations of a software component and used independently from the traced component. This approach is used to define a method for extending a java based CHR platform called CHROME (Constrain...

BACKGROUND In the present study, 4 different metallic implant materials, either partly coated or polished, were tested for their osseointegration and biocompatibility in a pelvic implantation model in sheep. METHODS Materials to be evaluated were: Cobalt-Chrome (CC), Cobalt-Chrome/Titanium coating (CCTC), Cobalt-Chrome/Zirconium/Titanium coating (CCZTC), Pure Titanium Standard (PTST), Steel, ...

EIn order to reduce formaldehyde emissions, an experimental investigation of lightweight flax shives based particleboards, prepared using two different binders: bio-based lignin (lignosulfonate) and partially epoxy resin (greenpoxy 56), was undertaken. The particleboards (with a target density 500 kg/m³), were elaborated by thermo-compression process 20 wt% binder content. directly valorised as...

Free content and services on the Web are often supported by ads. However, with the proliferation of intrusive and privacy-invasive ads, a significant proportion of users have started to use ad blockers. As existing ad blockers are radical (they block all ads) and are not designed taking into account their economic impact, ad-based economic model of the Web is in danger today. In this paper, we ...

The mortality experienced by a cohort of 2689 nickel/chromium platers between 1946 and 1983 has been investigated. All members of the study cohort had some period of chrome exposed employment. Overall, compared with the general population of England and Wales, statistically significant differences relating to cancer were found for cancer of the stomach (E = 16.2, O = 25), primary cancer of the ...
