Au-containing all-carbon 1,4-dipoles: generation and [4 + 2] annulation in the formation of carbo-/heterocycles.

Abstract: A novel concept of Au-containing all-carbon 1,n-dipoles is advanced. From 1-(1-alkynyl)cyclopropyl ketones, Au-containing all-carbon 1,4-dipoles are presumably generated in situ and can efficiently...

Improved Photocatalytic Degradation of Textile Dye Using Titanium Dioxide Nanotubes Formed Over Titanium Wires

Abstract: Titanium dioxide (TiO2) nanotubes formed by anodization over titanium wires show a significant improvement in photocatalytic activity compared to the nanotubes formed over foils. This is evident when the fractional conversion of a textile dye, methyl orange, increased from 19% over a foil to 40% over wires in the presence of nanotubes of identical dimensions illuminated over the same geometrical area. Higher degradation rates with Pt−TiO2 nanotubes over foils are matched by the Pt-free TiO2 nanotubes over the wires. The higher photocatalytic activity over the anodized wires can be attributed to the efficient capture of reflected and refracted light by the radially outward oriented TiO2 nanotubes formed over the circumference of the titanium wire. The formation of TiO2 nanotubes over wires can be considered as an effective alternate to improve photodegradation rates by avoiding expensive additives.

Explosives: a microsensor for trinitrotoluene vapour.

Abstract: Sensing devices designed to detect explosive vapours are bulky, expensive and in need of technological improvement — dogs remain the most effective detectors1 in the fight against terrorism and in the removal of land-mines2,3. Here we demonstrate the deflagration of trinitrotoluene (TNT) in a small localized explosion on an uncoated piezoresistive microcantilever. This explosive-vapour sensor, which has a detection capability that is comparable to that of a dog, should enable extremely sensitive, miniature detection devices to be used on a large scale.

Kinematics of the northern Walker Lane: An incipient transform fault along the Pacific–North American plate boundary

Abstract: In the western Great Basin of North America, a system of dextral faults accommodates 15%–25% of the Pacific–North American plate motion. The northern Walker Lane in northwest Nevada and northeast California occupies the northern terminus of this system. This young evolving part of the plate boundary offers insight into how strike-slip fault systems develop and may reflect the birth of a transform fault. A belt of overlapping, left-stepping dextral faults dominates the northern Walker Lane. Offset segments of a W-trending Oligocene paleovalley suggest ∼20–30 km of cumulative dextral slip beginning ca. 9–3 Ma. The inferred long-term slip rate of ∼2–10 mm/yr is compatible with global positioning system observations of the current strain field. We interpret the left-stepping faults as macroscopic Riedel shears developing above a nascent lithospheric-scale transform fault. The strike-slip faults end in arrays of ∼N-striking normal faults, suggesting that dextral shear diffuses into extension in the Great Basin. Coeval extension and dextral shear have induced slight counterclockwise fault-block rotations, which may ultimately rotate Riedel shears toward the main shear zone at depth, thus facilitating development of a throughgoing strike-slip fault.

Air pollution, oxidative stress, and Alzheimer's disease.

Abstract: Alzheimer's disease (AD) is the most common form of dementia affecting millions of people worldwide and will continue to affect millions more with population aging on the rise. AD causality is multifactorial. Known causal factors include genetic predisposition, age, and sex. Environmental toxins such as air pollution (AP) have also been implicated in AD causation. Exposure to AP can lead to chronic oxidative stress (OS), which is involved in the pathogenesis of AD. Whereas AP plays a role in AD pathology, the epidemiological evidence for this association is limited. Given the significant prevalence of AP exposure combined with increased population aging, epidemiological evidence for this link is important to consider. In this paper, we examine the existing evidence supporting the relationship between AP, OS, and AD and provide recommendations for future research on the population level, which will provide evidence in support of public health interventions.
