Noble gas bond and the behaviour of XeO.

Physical chemistry chemical physics : PCCP

Hou C, Wang X, Botana J, Miao M.
PMID: 28975946
Phys Chem Chem Phys. 2017 Oct 18;19(40):27463-27467. doi: 10.1039/c7cp05385a.

Over the past few decades, the concept of hydrogen bonds, in which hydrogen is electrophilic, has been extended to halogen bonds, chalcogen bonds and pnicogen bonds. Herein, we show that such a non-covalent bonding also exists in noble gas...

González L, Oria R, Botaya L, Puig-Vidal M, Otero J.
PMID: 25573912
Nanotechnology. 2015 Feb 06;26(5):055501. doi: 10.1088/0957-4484/26/5/055501. Epub 2015 Jan 09.

Quartz tuning forks have become popular in nanotechnology applications, especially as sensors for scanning probe microscopy. The sensor's spring constant and the oscillation amplitude are required parameters to evaluate the tip-sample forces; however, there is certain controversy within the...

Density functional study of the oxidation of small neutral and charged silver clusters.

Serantes D, Baldomir D, Pereiro M, Botana J, Prida VM, Hernando B, Arias JE, Rivas J.
PMID: 20355455
J Nanosci Nanotechnol. 2010 Apr;10(4):2512-7. doi: 10.1166/jnn.2010.1424.

Magnetic nanoparticles with controlled magnetocaloric properties are a good candidate to lower the temperature of nanosized systems: they are easy to manipulate and to distribute into different geometries, as wires or planes. Using a Monte Carlo technique we study...

Ophthalmomyiasis Externa: Case Report of the Clinicopathologic Features.

International Journal of Ophthalmic Pathology

Int J Ophthalmic Pathol. 2013 Feb 18;2(2). doi: 10.4172/2324-8599.1000106.

Ophthalmomyiasis externa is the infestation of the superficial external ocular structures by fly larvae. This is a particularly rare condition, which has nevertheless been reported in several countries worldwide. Presented herein are the clinicopathologic features of ophthalmomyiasis externa which...

Use of biosensors as alternatives to current regulatory methods for marine biotoxins.

Phys Rev Lett. 2019 Jun 21;122(24):247201. doi: 10.1103/PhysRevLett.122.247201.

Trilayer nickelates, which exhibit a high degree of orbital polarization combined with an electron count (d^{8.67}) corresponding to overdoped cuprates, have been identified as a promising candidate platform for achieving high-T_{c} superconductivity. One such material, La_{4}Ni_{3}O_{8}, undergoes a semiconductor-insulator...
