Magnetic sulfur-doped carbons for mercury adsorption.

Mercury pollution is a significant threat to the environment and health worldwide. Therefore, effective and low-cost absorbents that are easily scalable are needed for real-world applications. Enlarging the surface area of the materials and doping with heteroatoms are two of the most common strategies to cope with this problem.

Automated label flows for excited states of correlation functions in lattice gauge theory.

Extracting excited states from lattice gauge theory correlation functions can be achieved through χ^{2} minimization fits or algebraic approaches such as the variational method and Prony's method. Performing any kind of error analysis often leads to overlapping confidence regions of model parameters, even when the spectrum is not particularly dense. To correctly estimate errors, one must beware of mislabeling the states.

Nitric Oxide Releasing Titanium Surfaces for Antimicrobial Bone-Integrating Orthopedic Implants.

Titanium implants in orthopedic applications can fail due to infection and impaired integration into the host. Most research efforts that facilitate osseointegration of the implant have not considered infection, and vice versa. Moreover, most infection control measures involve the use of conventional antibiotics which contributes to the global epidemic of antimicrobial resistance.

Investigating the Antibacterial Properties of Inverse Vulcanized Sulfur Polymers.

More than 60 million tons of sulfur are produced as a byproduct of the petrochemical industry annually. Recently, the inverse vulcanization process has transformed this excess sulfur into functional polymers by stabilization with organic cross-linkers. These interesting new polymers have many potential applications covering diverse areas.

Effect of Polymer Demixed Nanotopographies on Bacterial Adhesion and Biofilm Formation.

As the current global threat of antimicrobial resistance (AMR) persists, developing alternatives to antibiotics that are less susceptible to resistance is becoming an urgent necessity. Recent advances in biomaterials have allowed for the development and fabrication of materials with discrete surface nanotopographies that can deter bacteria from adhering to their surface. Using binary polymer blends of polystyrene (PS), poly(methyl methacrylate) (PMMA) and polycaprolactone (PCL) and varying their relative concentrations, PS/PCL, PS/PMMA and PCL/PMMA polymer demixed thin films were developed with nanoisland, nanoribbon and nanopit topographies.

Nitric Oxide Releasing Polymeric Coatings for the Prevention of Biofilm Formation.

The ability of nitric oxide (NO)-releasing polymer coatings to prevent biofilm formation is described. NO-releasing coatings on (poly(ethylene terephthalate) (PET) and silicone elastomer (SE)) were fabricated using aminosilane precursors. Pristine PET and SE were oxygen plasma treated, followed by immobilisation of two aminosilane molecules: -(3-(trimethoxysilyl)propyl)diethylenetriamine (DET3) and -(3-trimethoxysilyl)propyl)aniline (PTMSPA).

Lattice study of the conformal window in QCD-like theories.

We study the extent of the conformal window for an SU(3) gauge theory with N{f} Dirac fermions in the fundamental representation. We present lattice evidence for 12 View Article and Find Full Text PDF

How can we learn to live with rivers? The findings of the Institution of Civil Engineers Presidential Commission on flood-risk management.

In the wake of the floods of 1998 and 2000 the Government invited the Institution of Civil Engineers (ICE) to carry out a technical review of flood-risk management in England and Wales and to consider the most appropriate approaches to flood-risk management for the 21st century. The findings of this Commission are published in the ICE report Learning to live with rivers. Further information on the Commission and its work is available at www.

Up quark mass in lattice QCD with three light dynamical quarks and implications for strong CP invariance.

A standing mystery in the standard model is the unnatural smallness of the strong CP violating phase. A massless up quark has long been proposed as one potential solution. A lattice calculation of the constants of the chiral Lagrangian essential for the determination of the up quark mass, 2alpha(8)-alpha(5), is presented.
