Consolidation of weathered limestone using nanolime
Limestone sourced from Salisbury Cathedral and Bath Abbey (UK) was treated with commercially available nanolime of concentration 25 g/l. The response of the stones to the treatment was studied using a variety of analysis...

Subtle Stereochemical Effects Influence Binding and Purification Abilities of an FeII4L4 Cage.
A tetrahedral FeII4L4 cage assembled from the coordination of triangular chiral, face-capping ligands to iron(II). This cage exists as two diastereomers in solution, which differ in the stereochemistry of their metal vertices...
Blow-up for the 3-dimensional axially symmetric harmonic map flow into <i>S<sup>2</sup></i>

We construct finite time blow-up solutions to the 3-dimensional harmonic map flow into the sphere S2, ut = ∆u + |∇u|2u in Ω × (0, T) u = ub on ∂Ω × (0, T) u(·, 0) = u0 in Ω, with u(x, t)...

Characterization of binders in the historic lime mortars and plasters from 1A Royal Crescent, Bath
There is a growing interest in the UK building industry to gain further knowledge of historic mortars. In 2011, permission was given by the Bath Preservation Trust to collect samples of historic lime mortars and plasters from 1A...
Radiocarbon dating of lumps from aerial lime mortars and plasters
This paper deals with the potentialities and technical and methodological issues associated with the use of lumps of not completely melted lime as material suitable for the radiocarbon dating of aerial lime mortars and plasters....
Nanostructured Pd hydride microelectrodes

In this study we report the exceptional potentiometric properties of pH microprobes made with nanostructured palladium hydride microelectrodes and demonstrate their application by monitoring pH variations resulting from a...

Scanning electrochemical microscopy

This study demonstrates how the potentiometric mode of the scanning electrochemical microscope (SECM) can be used to sensitively probe and alter the mixed potential due to two independent redox processes provided that the...

An experimental and computational study to resolve the composition of dolomitic lime
Lowering the environmental impact, and moving away from a reliance on cement based binders, is a key challenge of the construction industry. Dolomitic lime binders are produced at lower temperatures than cement, re-adsorb...

The Ethics of Astrobiology and the Cosmic Bet Argument
Luca Lo Sapio
Jan 01, 2024
Stephen Weinberg posited in 1977 that as the universe becomes more comprehensible, it appears more meaningless owing to a strict division between facts and values. He seemingly overlooked the consideration of the purposes and...
Selectivity-permeability optimization of functionalised CNT-polymer membranes for water treatment

Polymer membranes incorporating carbon nanotubes (CNT) belong to two broad categories: Vertically aligned (VA-CNT) membranes, where the polymer acts solely as a matrix embedding an aligned forest of nanotubes, and thin film...

Coherent backscattering of light by an anisotropic biological network.
The scattering strength of a random medium relies on the geometry and spatial distribution of its components as well as on their refractive index. Anisotropy can, therefore, play a major role in the optimization of the...
SOI CMOS MEMS infra-red thermal source with carbon nanotubes coating

This abstract presents the development of a Silicon-on-Insulator (SOI) CMOS micro-electro-mechanical (MEMS) micro-hotplate based infra-red (IR) light source employing a vertically aligned multi-walled carbon nanotubes...
