The effect of heat treatment on precipitation in the Cu-Ni-Al alloy Hiduron® 130
Cupronickel alloys, reinforced by L1$_2$ precipitates, offer a high strength, corrosion resistant and anti-bio fouling material for marine engineering applications. These alloys exhibit complex precipitate nucleation and growth...

In the accompanying Comment1, Stojanowski et al. challenge the evidence for inter-group conflict at Nataruk2. They make two arguments—first, that the lesions in three crania are due to soil compression; second, that there is a...
Recent advances in the application of group–10 transition metal based catalysts in C–H activation and functionalization
The importance of C–H bond activation in a simple molecule to form a molecule with enhanced functionality can be easily understood from a study of biological processes at a molecular level where, for example, a specific enzyme...

Understanding the timing and character of the expansion of Homo sapiens out of Africa is critical for inferring the colonization and admixture processes that underpin global population history. It has been argued that dispersal...
A low-temperature device architecture for the statistical study of
electrical characteristics of 256 quantum devices
H Al-Taie, LW Smith, B Xu, P See, JP Griffiths, HE Beere, GAC Jones, DA Ritchie, MJ Kelly, CG Smith
Feb 22, 2019
Research in the field of low-temperature electronics is limited by the small
number of electrical contacts available on cryogenic set ups. This not only
restricts the number of devices that can be fabricated, but also the device...

Structure and triclustering in Ba-Al-O glass
Glass-forming ability in the (BaO) x(Al 2O 3) 1-x system (0≤x≤1) was investigated by using the containerless aerodynamic levitation and laser-heating method. The main glass-forming region was found to occur for 0.40(2) ≤x≤...

Sep 01, 2020
The first example of enantioselective S‐H insertion reactions of sulfoxonium ylides is reported. Under the influence of thiourea catalysis, excellent levels of enantiocontrol (up to 95% ee) and yields (up to 97%) are achieved...
Rubidium and caesium aluminyls
