6:20 PM | In the Lab: Rational Studies Towards Efficient, Scalable Catalytic Reactions
Here we profile an upcoming researcher who has benefitted from Johnson Matthey’s support in the past. David Nelson is a newly appointed Chancellor’s Fellow and Lecturer at the University of Strathclyde, in Glasgow, UK. His research interests concern the development of useful transition metal catalysed processes for synthesis via a detailed understanding of mechanism, rate...

6:20 PM | Is Osmium Always the Densest Metal?
Having established that osmium is the densest metal at room temperature the question arises as to whether it is always the densest metal. It is shown here that at ambient pressure osmium is the densest metal at all temperatures, although there is an ambiguity below 150 K. At room temperature iridium becomes the densest metal above a pressure of 2.98 GPa, at which point the densities of the two metals are equal at 22,750 kg m–3.

6:20 PM | Dennis Dowden and the Development of Catalytic Science
In the twentieth century Dennis Albert Dowden, affectionately referred to as DAD by friends and colleagues, was an important figure in the development of an understanding of the structure of industrial heterogeneous catalysts, the species present and the processes taking place on them. He was born in Bristol, UK, and following education at the University of Bristol and a short period at Amherst College in the USA, in 1938 he joined Imperial Chemical Industries (ICI) at Billingham in the North […]

6:20 PM | Platinum Group Metal Catalysed Hydrodeoxygenation Of Model Bio-oil Compounds
Introduction The use of biomass as a starting point for the manufacture of chemicals and fuels has been the subject of increasing research effort in recent years. A wide range of biomass sources are being investigated and reported in the literature, but with a particular focus on second generation biorenewables, which use non-food sources of...

6:20 PM | Thermophysical Properties of Platinum Group Metals in their Liquid Undercooled and Superheated Phases
This review briefly describes the vacuum electrostatic levitation furnace developed by JAXA and the associated non-contact techniques used to measure the density, the surface tension and the viscosity of materials. The paper then presents a summary of the data taken with this facility in the equilibrium liquid and non-equilibrium liquid phases for the six platinum group metals (pgms): platinum, palladium, rhodium, iridium, ruthenium and osmium over wide temperature ranges that include […]

6:20 PM | Comparative Investigations on Platinum Cluster Salts
To evaluate future applications of metallic clusters in nanoscience and nanotechnology, the electronic properties of the high-nuclearity carbonyl anionic platinum cluster [Pt19(CO)22]4– were investigated using two different organic cations. In particular, N,N'-diethyl viologen dication (Vio2+) and N,N'-dimethyl-9,9'-bis-acridinium dication (Acr2+) were employed as counterions, oxidising agents and characterisation probes. The reactions of [Pt19(CO)22]4– tetra-n-butylammonium salt, […]

I am an alcoholic. I claim that label, because it’s true. I am an alcoholic in recovery. I use “recovering”, “recovered”, and “in recovery” interchangeably. Some people in AA argue about the use of particular terms. In particular, some people object to “recovered” because it sounds too final, and we live a day at a […]

5:00 AM | Adaptive-Rate Compressive Sensing Using Side Information - implementation -
Adaptive-Rate Compressive Sensing Using Side Information by Garrett Warnell, Sourabh Bhattacharya, Rama Chellappa, Tamer BasarWe provide two novel adaptive-rate compressive sensing (CS) strategies for sparse, time-varying signals using side information. Our first method utilizes extra cross-validation measurements, and the second one exploits extra low-resolution measurements. Unlike the majority of current CS techniques, we do not assume that we know an upper bound on the number of […]

2:27 AM | Science Blogging: Got Comments?
In a recent study of science bloggers, Merja Mahrt and Cornelius Puschmann found that the blog author very much influences the degree of commenting on his or her own blog posts. How? Through language complexity and topic selection. In a content analysis of over 200 posts at scienceblogs.com, researchblogging.org, hypotheses.org, amazings.es and scilogs.de (the German partner of SciLogs.com), these researchers found blog posts that received the most comments dealt either with common […]
