Academy of Finland Researchers from the University of Jyväskylä report a new method of building molecular cages. The method involves the exploitation of intermolecular steric effects to control the outcome of a self-assembly reaction. Molecular cages are composed of organic molecules (ligands) which are bound to metal ions during a self-assembly process. Depending on the prevailing conditions, self-assembly processes urge to maximize the symmetry of the system and thus occupy every...

Lead sulfide (PbS) forms when an equal number of lead and sulfur atoms exchange electrons and bond together in cubic crystals. Now scientists have determined that a structure comprising 32 lead-sulfur pairs is the smallest possible cubic arrangement that exhibits the same coordination as bulk lead sulfide. (The coordination number is the number of nearest neighbors each atom in the crystal has.) Researchers from McNeese State University in Louisiana, John Hopkins University in Maryland,...

Chemical compounds called manganites have been studied for many years since the discovery of colossal magnetoresistance, a property that promises important applications in the fields of magnetic sensors, magnetic random access memories and spintronic devices. However, understanding"”and ultimately controlling"”this effect remains a challenge, because much about manganite physics is still not known. A research team lead by Maria Baldini from Stanford University and Carnegie...

Researcher Kristina Djanashvili has developed a substance that enables doctors to get better MRI scans of tumours. On Tuesday 13 January, Djanashvili will be awarded a doctorate by TU Delft for her work in this field.The medical profession's ability to trace and visualise tumours is increasing all the time. Detection and imaging techniques have improved enormously in recent years. One of the techniques that have come on by leaps and bounds is MRI. Patients who are going to have MRI scans are...

New method 'self-assembles' metal atoms into porous nanostructures For 5,000 years the only way to shape metal has been by the "heat and beat" technique. Even with modern nanotechnology, metalworking involves carving metals with electron beams or etching them with acid. Now Cornell researchers have developed a method to self-assemble metals into complex configurations with structural details about 100 times smaller than a bacterial cell by guiding metal particles into the desired form using...

Research and Markets (http://www.researchandmarkets.com/reports/c81890) has announced the addition of "The Chemical Bond in Inorganic Chemistry: The Bond Valence Model" to their offering. The bond valence model is a recently developed model of the chemical bond in inorganic chemistry that complements the bond model widely used in organic chemistry. It is simple, quantitative, intuitive, and predictive - no more than a pocket calculator is needed to calculate it. This book focuses on...

grass-comber
  • A landsman who is making his first voyage at sea; a novice who enters naval service from rural life.
According to the OED, a grass-comber is also 'a sailor's term for one who has been a farm-labourer.'
