This article from the Numismatist journal discusses King Hieron II of Syracuse and his request for a scientist to determine whether his new crown was made of pure gold or an alloy. The scientist in question is the famous Archimedes, who used the principle of displacement to figure out the crown's volume and discovered that it was indeed alloyed with silver. The article also mentions Hieron II's extensive coinage, which includes gold, silver, and bronze issues featuring portraits of Hieron himself, his wife Philistis, and his son Gelon. The coinage is collectible across all price ranges and can be found at auction or through patience. [Extracted from the article]

Pulling teeth If you first take 33 teeth - each removed from its original home inside some human mouth - then stain every one with coffee, then, finally, on each tooth apply either a "charcoal-based tooth whitening dentifrice" or a "non-charcoal-based whitening dentifrice" to try to remove the coffee stains, you will discover something. They discovered, they say, that "a charcoal-based tooth-whitener does not make a tooth appreciably whiter than a non-charcoal-based tooth-whitener". Lambe's study is called "Genetic associations of ewe body condition score and lamb rearing performance in extensively managed meat sheep". [Extracted from the article]

• The Au-PtNCs have been controlled prepared through a hydrothermal method. • The Au-PtNCs show optimal catalytic activity for TMB oxidation. • Doping with platinum is the most efficient way to improve the catalytic properties. • The Au-PtNCs are applied to colorimetric determine H 2 O 2 with high sensitivity. In the present study, we have prepared glutathione capped gold and platinum alloy nanoclusters (Au-PtNCs) in a controlled way by employing the hydrothermal method and optimized through adjusting the ratio of raw materials, reaction temperature, and time. Compared with the corresponding monometallic gold and platinum nanoclusters, the alloy nanoclusters' catalytic activity is improved dramatically in the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) in the presence of H 2 O 2. And the maximum velocity is calculated to be 106 × 10−8 M · s−1 for TMB as substrate, being much better than that of other reported metallic nanoclusters and nanoparticles. Further study shows that the high catalytic activity mainly attributes to the synergistic effect of gold and platinum. Besides, they have been applied to determine H 2 O 2 in the presence of TMB, which shows high sensitivity with a limit of detection (LOD) at 100 nM. The proposed method has been used to determine H 2 O 2 in milk and contact lens solutions, which shows very good recovery and exhibits high practical application potential. Therefore, the present study provides a new type of alloy nanoclusters with high peroxidase-like activity, which will inspire more research interests on doping and alloying with Pt to improve the catalytic activity of metal nanoclusters.

SPORT QUATTRO v IMPREZA 22B v GR YARIS Subaru's Impreza 22B and Audi's SportQuattro are rally-inspired, four-wheel-drivelegends. Could Toyota's GR Yaris match themfor charisma and ability? Conversely, while the short-wheelbase Quattro may havestruggled to keep pace with the Peugeots and Lancias onthe rally stages, the road cars built and sold to facilitateits homologation were by far the most complete and fullydeveloped of all the Group B contemporaries. Another quality the Yaris shares with its spiritualforebears is an unusual and characterful powertrain, itsgutsy turbocharged triple deviating from the norm just asSubaru's forced induction flat-four and Audi's in-line five-cylinderturbo did in their day.

FEATURES If all the world were a movie, you could probably freeze-frame the exact point at which the great British sports car died to some time in 1980, when the MGB finally went out of production after the best part of 20 years, just after the Midget and alongside its great rival the Triumph Spitfire. Robinson had honed his engineering skills building Graham Hill's Grand Prix cars in the early 1960s, but his new venture, Vegantune, was dedicated to Lotus models from the off, with a particular focus on the diminutive Elan and the fire-breathing 26R that was launched the same year his company was founded. Hethel still had an obligation to support Caterham, however, so turned to the firm that had been so successful in tuning and rebuilding the engines in the past: Vegantune.

Abstract
Researchers from the University of Padova in Italy have published a study on the cytotoxicity of gold and gold-iron alloy nanoparticles (NPs) coated with biocompatible polymers. The study found that NPs larger than 200 nm were less tolerable to cells, and the most tolerable formulations were pure PEG-Au NPs and PEG-Au-Fe NPs with a hydrodynamic size of less than 50 nm. Tumor cells and highly proliferating cells were more sensitive to the NPs than fibroblasts, and the presence of catalase had a protective effect on cells incubated with PEG-Au-Fe NPs. The results of this study are important for the development of biocompatible gold NPs and biodegradable gold-iron alloy NPs, and the findings have broader implications for other types of nanomaterials.

• A constant strain rate membrane deflection experiment (MDE) methodology is developed. • FEA is performed to investigate potential sources of error in MDE. • Mechanical properties of thin films measured by MDE and micro-tensile test are compared. • The stress-strain curves of Au, Al, and NiMoW films are successfully measured via MDE. • Yield stress obtained by constant strain rate MDE well matches with that from tensile test. The mechanical behavior of freestanding metal thin films (gold, aluminum, and nickel-molybdenum-tungsten alloy) is characterized using micro-tensile testing and membrane deflection experiment (MDE). Micro-tensile and membrane samples are simultaneously fabricated on a single wafer to avoid microstructural differences. A constant strain rate MDE methodology is developed to directly compare each test method. Finite element analysis is performed to investigate potential sources of error in MDE. Specifically, the effects of in-plane and out-of-plane misalignment, tip blunting, sample dimension, and substrate deformation are studied, and physical insights gained from the analysis were applied to the experiments. By comparing with the micro-tensile tests, it is experimentally demonstrated that the stress-strain curve of freestanding metal thin films can be successfully measured via constant strain rate MDE. In particular, yield stress shows a good agreement with that obtained from micro-tensile tests, demonstrating the usefulness of applying the constant strain rate methodology in MDE testing. Furthermore, MDE enables residual stress measurements of the deposited films. Constant strain rate MDE developed in this study can serve as a useful technique for high-throughput measurement of in-plane mechanical properties of metal thin films. [ABSTRACT FROM AUTHOR]

Abstract
Pt–Au alloy nanowires have been controllably electrodeposited on microelectrodes by applying an alternating current and were used as the electrocatalyst for formic acid oxidation. The frequency and voltage of the alternating current and the electrolyte composition were adjusted to precisely control the morphologies, alloying structures and composition. The characteristics of Pt–Au alloy nanowires were analyzed by scanning electron microscopy, X-ray diffraction and transmission electron spectroscopy. Electrocatalytic performance of formic acid oxidation at Pt–Au alloy nanowires electrode was investigated by cyclic voltammetry and chronoamperometry. The results showed that the Pt–Au alloy nanowires possessed highly-crystalline morphologies, the controllable bimetallic composition and single-phase alloy structures, which mainly grow in the <111> crystal orientation. The electrocatalytic activity of formic acid oxidation strongly depended on the bimetallic Pt/Au composition. The Pt 35 Au 65 alloy nanowires displayed superior electrocatalytic performance and high stability toward the electrooxidation of formic acid in acidic solution, owing to the ensemble effect of the Pt and Au components. These findings provided insights into the design of the Pt–Au bimetallic nanomaterials as electrocatalysts for formic acid oxidation. [ABSTRACT FROM AUTHOR]
An Au–Pd–Co–Ni–V brazing alloy was designed for AlN ceramic joining. Its wettability on AlN was studied with the sessile drop method. The results showed that the contact angle was decreased gradually with increasing temperature and the prolonging of holding time. Sound AlN/AlN joints were achieved with the brazing alloy at 1170 °C for 10 min. The microstructure of the AlN/AlN joints was examined by scanning electron microscopy (SEM). It was found that element V played the active role in the interfacial reaction between the ceramic and the brazing alloy. V reacted with N decomposed from AlN, resulted in the formation of V–N compound. Based on the energy-dispersive spectroscopy (EDS) and X-ray diffraction (XRD) analysis results, the V–N reaction product was verified as V 2 N. The overall reaction during the brazing process can be described by the following equation: 2V + AlN + 2Pd = V 2 N + Pd 2 Al. The AlN/AlN joints brazed with the Au–Pd–Co–Ni–V brazing alloy exhibited three-point bend strength of 162.7 MPa at room temperature, and under the bend test the fracture of the joint occurred at the AlN ceramic substrate.

Abstract
In this paper we report the results of a deep investigation of gold title in jewellery alloys by means of potentiometric titration. After reviewing the suitable reactions for such purpose we focused on the most profitable one, which involves the use of hexadecylpyridinium chloride (CPC). This cation gives rise to selective and quantitative precipitation of AuCl . We completely revised a method previously proposed by W.S. Selig in the 80's, by improving the sampling preparation and by optimizing the titration steps. Then, the new proposed method was tested on a large number of different alloys, commonly used for goldsmithery purposes. The obtained gold titles were compared with the data achieved by fire assay, giving rise to a very good agreement. At the light of these results, the present method can be rightfully considered a cheaper and 'greener' alternative to the traditional one. [ABSTRACT FROM AUTHOR]

Abstract
Gold-tin (Au-Sn) alloys are lead-free solder materials used in the electronic and optoelectronic industries. An economical method of depositing the solder is by co-electroplating the two components from a single bath. In this work, the effects of bath composition and pulse current (PC) plating factors on the composition, micro-structure and plating rate of Au-Sn deposits have been investigated. The transition current density for plating the two different gold-tin intermetallics, Au5 Sn and AuSn, was shifted to a lower current density at lower ammonium citrate concentration. Deposits plated from solutions with 100g/L (13.3 oz/gal) ammonium citrate were denser and smoother than those obtained from solutions with 200 g/L (26.7 oz.gal) ammonium citrate. The polariztion behavior of plating baths with different ammonium citrate concentrations corresponded to their plating rates. Thin film x-ray diffraction studies showed that only Au5Sn and/or AuSn were plated out in the deposits. The growth of both Au5Sn and AuSn phases was not oriented. [ABSTRACT FROM AUTHOR]
Liquid metal runs through these new flexible circuits but before the boffins even think of making things like touch-sensitive robot skin for humans, first off they need to get the flexible electronics right, and make sure they are tough and reliable.
