, 2013 This chapter deals with the electronic structure of metal-metal bonds in molecular systems, a diverse topic that now spans almost the entire periodic table. The field is most often associated with strong multiple bonds such as the iconic quadruple bond in [Re2Cl8]2-, and the recently discovered ultra-short Cr-Cr quintuple bonds provide a remarkable ...

SmallTalk: a novel small‐sized fusion tag for peptide expression and purification
FEBS Open Bio, EarlyView.The SmallTalk fusion tag allows for the efficient expression and purification of soluble recombinant proteins or peptides in Escherichia coli. Testing with SmallTalk‐GFP confirmed that the proteins were soluble and folded correctly, while SmallTalk‐Bin1b maintained its antimicrobial activity against various bacterial isolates. This streamlined workflow

Wire winding increases lifetime of oxide coated cathodes [PDF]
, 1965 Refractory-metal heater base wound with a thin refractory metal wire increases the longevity of oxide-coated cathodes. The wire-wound unit is impregnated with the required thickness of metal oxide.

Toxicity of Pb and of Pb/Cd combination on the springtail Folsomia candida in natural soils: Reproduction, growth and bioaccumulation as indicators [PDF]
, 2012 The toxicity of Pb and Cd+Pb was assessed on the Collembola F. candida in two cultivated soils (SV and AU) with low organic matter (OM) content and circumneutral to basic pH, and an acid forested soil (EPC) with high OM content.

FEBS Open Bio, EarlyView.This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Characteristics of EMI generated by negative metal-positive dielectric voltage stresses due to spacecraft charging [PDF]
, 1985 Charging of spacecraft surfaces by the environmental plasma can result in differential potentials between metallic structure and adjacent dielectric surfaces in which the relative polarity of the voltage stress is either negative dielectric/positive ...

Wideband Optical Filters with Small Gap Coupled Subwavelength Metal Structures
, 2012 In this letter, we show that the bandwidth of optical band-stop filters made of subwavelength metal structures can be significantly increased by the strong plasmonic near-field coupling through the corners of the periodic metal squares.

Arthritis Care &Research, EarlyView.Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain, and magnetic resonance imaging–confirmed midfoot BMLs ...

Resolving scientific controversy over smelter risks and neurodegenerative effects of metals
AIMS Environmental Science, 2015 Although it is well known that metals pollution can cause neurotoxic effects, scientists are currently divided about the neurodegeneration hypothesis. That is, some scientists accept, while others fail to accept, the hypothesis that metals/metalloids, at
