Antimicrobial Properties of the Ag, Cu Nanoparticle System
Simple Summary The antimicrobial properties of Ag and Cu nanoparticles, their mixtures and their alloys, are reviewed. Abstract Microbes, including bacteria and fungi, easily form stable biofilms on many surfaces.

According to the antagonistic pleiotropy theory of ageing, natural selection has favoured genes conferring short-term benefits to the organism at the cost of deterioration in later life. The 'disposable soma' theory expresses this as a life-history strategy in which somatic maintenance is below the level required to prevent ageing, thus enabling higher

Thickness-dependent humidity sensing by poly(vinyl alcohol) stabilized Au–Ag and Ag–Au core–shell bimetallic nanomorph resistors [PDF]
We herein report a simple chemical route to prepare Au–Ag and Ag–Au core–shell bimetallic nanostructures by reduction of two kinds of noble metal ions in the presence of a water-soluble polymer such as poly(vinyl alcohol) (PVA).

BACKGROUND Traditional inductively coupled plasma-mass spectrometry (ICP-MS) determination of trace elements such as Ag and Cd in geochemical samples is seriously affected by the matrix effect and multiple polyatomic ions, making it difficult to measure ...

MARK-AGE biomarkers of ageing [PDF]
Many candidate biomarkers of human ageing have been proposed in the scientific literature but in all cases their variability in cross-sectional studies is considerable, and therefore no single measurement has proven to serve a useful marker to determine, on its own, biological age.

Age and Ageing: An Overview [PDF]
Europe is ageing, as exemplified by the UK population where, in the foreseeable future, more people will be over than under age 50: industry appears slow to recognise and appreciate all that older workers still have to offer: bundling them off into early retirement wastes precious talents. Memory difficulty is not an inevitable part of ageing.

The future of Age and Ageing [PDF]
The delivery of healthcare in the United Kingdom is going through a period of change, with many new developments. Some of these represent the aspirations of politicians and those who manage the National Health Service, and others are being forced upon us because of the shortage of resources (not always financial).
