The purpose of this paper is to synthesize a novel kind of crown‐type phosphate ionic liquids with better tribological properties for steel/Al system. The anions of crown‐type phosphate ionic liquids contain no F element, which are non‐corrosive to metal.

To improve the tribological properties of ionic liquid lubricants for the extremely difficult system of the steel‐against‐aluminum metal couple, novel crown‐type phosphate ionic liquids were prepared. The tribological properties of the crown‐type phosphate ionic liquids were evaluated at different loads and frequencies on an Optical SRV oscillating friction and wear tester. The morphology and chemical compounds of the wear scars were investigated by scanning electron microscope (SEM) and X‐ray photoelectron spectroscopy (XPS).

Compared with conventional ionic liquids, the novel crown‐type phosphate ionic liquids prepared in the present work exhibit a more excellent anti‐wear ability for steel/Al2024 contact at different loads and frequencies. By the morphological analysis with SEM, less debris was observed in the worn surface lubricated with crown‐type phosphate ionic liquids, though more debris was observed when lubricated with LB106 and LP106. By the XPS analysis, boundary lubrication film composed of aluminum (III) oxide, organometallic compounds, and silicon aluminum phosphate were found in the worn surface. Namely, the tribological behaviors of the crown‐type phosphate ionic liquids could be attributed to their stronger adsorption and tribochemical interactions with the Al alloys.

Because of the higher mean friction coefficients of crown‐type phosphate ionic liquids in the research, researchers are encouraged to modify their structure for better tribological properties.

The crown‐type phosphate ionic liquid exhibited better anti‐wear performance for steel/aluminum contact than the conventional ionic liquids containing F element. This will expand the application of high strength aluminum alloys.

The phosphate ionic liquid is a non‐corrosive liquid and would not cause metal corrosion. Also, the tribological properties of crown‐type phosphate ionic liquid with steel/aluminum contact are better than that of conventional ionic liquids. By the designing of molecular structure, new phosphate ionic liquids will exhibit excellent tribological properties: lower wear volume and lower friction coefficient.

The Institution of Chemical Engineers sponsored this series of lectures on the information programmes of the American Institute of Chemical Engineers, the Engineers Joint Council, and other organizations of interest to those in science and technology. The Institution has been interested in these developments and wants to assess what role it should play in the processing of technical information. From the trends of these organizations and from the developments in equipment and microforms patterns are emerging which will help the information officer in his work.

The purpose of this study is to evaluate the quality of organometallic coatings of automotive fuel tanks. Galvannealed steels and galvannealed steels coated with organometallic layers were analyzed using accelerated corrosion tests.

The characterization of galvannealed and organometallic coatings was done by mass (layer removal and weighing) and layer thickness (glow discharge optical emission spectroscopy and scanning electron microscopy), chemical composition (energy dispersive spectroscopy) and surface morphology (scanning electron microscopy). The accelerated corrosion tests were performed in accordance with SAE J2334 and GMW 14872 standards.

The samples tested using the GMW 14872 standard were more deteriorated as compared to the samples submitted to the SAE J2334 test because of the higher degree of aggressiveness of the GMW 14872 test. Despite the presence of white rust, the corrosion resistance of organometallic-coated steel samples was higher as compared to the resistance of galvannealed steel samples.

The organometallic coating is a commercial product, whose chemical composition is confidential.

This study reinforces the quality of automotive tanks with organometallic coating and helps to increase their competitiveness in the market tanks as compared to polymeric tanks.

The study contributes to increase the competitiveness of steel tanks against polymeric tanks that meet the technical requirements but are not environmentally friendly because they are multi-layered and cannot be recycled.

The novelty of this study is the comparison of the corrosion resistance of galvannealed steel tanks and galvannealed steel tanks with organometallic coatings. This corrosion evaluation joined with the physical and chemical characterization was not found in literature and is relevant to the materials selection of the automotive industry.

A dewaxed and dearomatized petroleum fraction having a boiling range 180–250°C was oxidised by air at 140°C. under atmospheric pressure using cobalt or manganese naphthenate as catalyst. The oxynaphthenic acids were isolated from the oxidation product, purified and then neutralised to sodium salts.

When the CrossFire databases were released in 1994, chemical information became available in electronic form of a quality and quantity never before accessible to end‐users. Describes the information sources used by chemists before CrossFire and the origins of the CrossFire database. Discusses the content and functionality of CrossFire, and provides examples to illustrate its capabilities. The database allows chemists to search in their own language of structures, reactions and properties, and this has had an impact on the type of chemical information searching possible. Makes particular reference to the CrossFire service provided by MIMAS to the UK and Scandinavian academic communities. Also mentions the position of CrossFire in the chemical information landscape, along with news of expected developments.

To discuss synthesis and evaluation of organo‐metallic chalcones as second‐order nonlinear optical (SONLO) materials.

The new chalcones have been synthesised via Knovoenagel reactions of ferrocen carboxaldehyde with two active methylene compounds.

The ferrocenyl chalcones prepared have shown bathochromic shift and thermal stability in polymeric film. On heating the dye films up to 80°C the extent of degradation reached up to 12 per cent and very small amount of degradation was observed at 43 and 60°C.

The paper shows that these compounds have UV‐Vis bathochromic shift, enabling them to be used as SONLO materials in the blue domain as well as dyes.

Chemical Abstracts Service has recently introduced a new data base, CA SEARCH, which is supposed to replace CA CONDENSATES and CASIA, and which is, in effect, a combination of the two. Two major U.S. search services, Lockheed Retrieval Service (LRS) and System Development Corporation (SDC), offer access to CA SEARCH. Bibliographic Retrieval Service (BRS) will also soon load CA SEARCH, but is presently offering CA CONDENSATES.

The corrosion performance of ceramic films of SiO₂‐Al₂O₃ prepared by the sol‐gel processing of organometallic compounds and deposited by dip‐coating technique on 1008 steel foils has been evaluated. Two kinds of procedures were developed to produce the sol‐gel coatings. The influence of the coatings on the chemical corrosion of the substrate has been measured by using potentiodynamical polarization curves in 0.5 M H₂SO₄ and 1 M HCl solutions at room temperature. Sol‐B showed the best behaviour in protective corrosion, in addition to the fact that the number of applications does not influence the resistant corrosion. Protection of coatings was limited by the growing of film cracking due to residual stress between coating and substrate. The results were supplemented by SEM analysis.

Finally relevant applications of this technology are described.

Inkjet printing is currently one of the cheapest direct write techniques for manufacturing. The use of this technique in electronic manufacturing, where interconnects and other conductive features are required is an area of increasing relevance to the fields of electronics manufacturing, packaging and assembly. This review paper would therefore be of great value and interest to this community.

This paper aims to investigate the composition of lubricant and the enhancement of tribological properties using palm oil as a parent base oil mixed with an organo-zinc compound as an additive.

The oil samples were prepared by mixing organo-zinc compound additive, zinc dioctyldithiophosphate (ZnDoDP) and zinc diamyldithiocarbamate (ZDDC), at 0 to 3.0 Wt.% concentrations with commercialised palm oil which were then homogenised using an ultrasonic homogeniser. The oil samples were then tested for their oil properties through elemental analysis, their viscosity index, flashpoint and acid number. Next, the friction test was performed using a four-ball tribometer, and the worn surfaces of the balls were observed using a digital microscope.

The results showed that commercialised palm oil with 2.0 Wt.% of ZnDoDP had excellent characteristics regarding its lubricant properties, such as its viscosity index, coefficient of friction and wear compared to commercialised palm oil with the addition of 2.0 Wt.% of ZDDC.

To the best of the authors’ knowledge, this is the first study to compare the effect of the concentration of ZnDoDP and ZDDC on the lubricant and triological properties of vegetable oil (palm).
