The isocyanide complexes cis-[MCl2(CNC6H4-4-X)2] (M = Pd; X Cl, Br; M Pt; Br) form isomorphous crystal structures exhibiting the Cl/Br and Pd/Pt exchanges featuring 1D chains upon crystallisation. Crystal packing is supported by C–X···X–C halogen bonds (HaBs), C–H···X–C hydrogen (HB), X···M semicoordination, C···C contacts between C atoms of aryl ligands. results DFT calculations topological an...

In present investigation L-lysine doped ADP crystal has been grown by slow evaporation technique. The crystalline nature of the grown crystal was confirmed using powder X-ray diffraction technique. The optical studies were carried to examine optical transparency and determine the optical constants of the grown crystal quenching the optoelectronics applications. The optical band gap of grown cry...

We show that SiO x , deposited at 5° to the interior surface of a liquid crystal cell allows for a surprisingly substantial reduction in the ion concentration of liquid crystal devices. We have investigated this effect and found that this type of film, due to its surface morphology, captures ions from the liquid crystal material. Ion adsorption on 5° SiO x film obeys the Langmuir isotherm. Expe...

A crucial issue in coherent x-ray diffraction imaging experiments is how to increase the signal-to-noise ratio when measuring relatively weak diffraction intensities from a nonperiodic object. A novel crystal guard aperture is described that makes use of a pair of multiple-bounce crystal optics to eliminate unwanted parasitic scattering background. This background is often produced by upstream ...

X-ray protein crystallography has, through the determination of the three-dimensional structures of enzymes and their complexes, been essential to the understanding of biological chemistry. However, as X-rays are scattered by electrons, the technique has difficulty locating the presence and position of H atoms (and cannot locate H+ ions), knowledge of which is often crucially important for the ...
