    Microscopy techniques for determining water–cement (w/c) ratio in hardened concrete: a round-robin assessment

    Water to cement (w/c) ratio is usually the most important parameter specified in concrete design and is sometimes the subject of dispute when a shortfall in concrete strength or durability is an issue. However...

    Structure sensitivity in acetylene reactions over bimetallic Pd/W surfaces

    Acetylene reactions over a Pd/W(111) surface are found to exhibit size effects on the nanometer scale. Upon annealing 1 ML Pd/W(111), pyramidal facets are formed having bcc(211) faces with nanometer dimensions...
