Optical pump-probe spectroscopy is a powerful tool for the study of non-equilibrium electronic dynamics and finds wide applications across a range of fields, from physics and chemistry to material science and biology. However, a...
Boundaries, Vermas and factorisation
Abstract: We revisit the factorisation of supersymmetric partition functions of 3d N = 4 gauge theories. The building blocks are hemisphere partition functions of a class of UV N = (2, 2) boundary conditions that mimic the...

Visible-Light Promoted C-O Bond Formation with an Integrated Carbon Nitride-Nickel Heterogeneous Photocatalyst.
Ni-deposited mesoporous graphitic carbon nitride (Ni-mpg-CNx ) is introduced as an inexpensive, robust, easily synthesizable and recyclable material that functions as an integrated dual photocatalytic system. This material...
MANUFACTURING MULTI-MATRIX COMPOSITES:
The formation of porosity is a major challenge in any composite manufacturing process, particularly in the absence of vacuum assistance. Highly localised injection of polymer matrix into regions of interest in a dry preform is a...

The known unknowns of assisted hydration at the end of life.
Much is unknown about assisted hydration at the end of life: why rates of usage vary so highly between institutions, cultures and countries, what beneficial or burdensome effects this treatment has, whether there is a place for...
What is the impact of clinically assisted hydration in the last days of life? A systematic literature review and narrative synthesis.
BACKGROUND: Clinically assisted hydration (CAH) can be provided in the last days of life as drinking declines. The impact of this practice on quality of life or survival in the last days of life is unclear. Practice varies...

Jan 29, 2020
A triphasic photocatalytic reactor employing a mesoporous carbon nitride photocatalyst and aerobic O2 was assembled to operate under continuous flow conditions. This reactor design allows for facile downstream processing and...
Bridging Plastic Recycling and Organic Catalysis
Tengfei Li, Arjun Vijeta, Carla Casadevall, Alexander S Gentleman, Tijmen Euser, Erwin Reisner
Aug 25, 2022
Chemical recycling of synthetic polymers represents a promising strategy to deconstruct plastic waste and make valuable products. Inspired by small-molecule C-H bond activation, a visible-light-driven reaction is developed to...
Comparison of the measurement performance of high precision multi-axis metal cutting machine tools
High precision manufacturers continuously seek out disruptive technologies to improve the quality, cost, and delivery of their products. With the advancement of machine tool and measurement technology many companies are ready...
ET-traps offer a potential therapeutic tool for use in different autoimmune diseases.
Research shows that endothelin (ET)-traps are a potential therapy for diabetes. Given that type 1 diabetes mellitus (T1DM) is an autoimmune disorder, ET-traps could also have an efficacious, therapeutic effect on other...

Inter-adsorbate forces and coherent scattering in helium spin-echo experiments.
David J Ward, Arjun Raghavan, Anton Tamtögl, Andrew P Jardine, Emanuel Bahn, John Ellis, Salvador Miret-Artès, William Allison
Oct 07, 2020
In studies of dynamical systems, helium atoms scatter coherently from an ensemble of adsorbates as they diffuse on the surface. The results give information on the co-operative behaviour of interacting adsorbates and thus...
Extracting in Situ Charge Carrier Diffusion Parameters in Perovskite Solar Cells with Light Modulated Techniques.
