Influence of heat treatment on structural, mechanical and wear properties of crosslinked UHMWPE.

Journal of applied biomaterials & biomechanics : JABB

Chiesa R, Moscatelli M, Giordano C, Siccardi F, Cigada A.
PMID: 20803447
J Appl Biomater Biomech. 2004 Jan-Apr;2(1):20-8.

New crosslinked ultra high molecular weight polyethylenes (UHMWPEs) have recently been developed, characterized and introduced in clinical applications. UHMWPE cross-linking treatments are very promising for reducing osteolysis induced by wear debris. The irradiation type, gamma or beta, the dosage...

Multifrequency AFM: from origins to convergence.

Nanoscale

Santos S, Lai CY, Olukan T, Chiesa M.
PMID: 28394393
Nanoscale. 2017 Apr 20;9(16):5038-5043. doi: 10.1039/c7nr00993c.

Since the inception of the atomic force microscope (AFM) in 1986, influential papers have been presented by the community and tremendous advances have been reported. Being able to routinely image conductive and non-conductive surfaces in air, liquid and vacuum...

A cost analysis of thyroid core needle biopsy vs. diagnostic surgery.

Gland surgery

Trimboli P, Nasrollah N, Amendola S, Crescenzi A, Guidobaldi L, Chiesa C, Maglio R, Nigri G, Pontecorvi A, Romanelli F, Giacomelli L, Valabrega S.
PMID: 26312216

BACKGROUND: Twenty percent of thyroid fine needle aspiration (FNA) is indeterminate. Because 3 in 4 of these are actually benign, a method of clarifying the pathology could help patients to avoid diagnostic thyroidectomy. Recently, core needle biopsy (CNB) has...

Sun-tracking optical element realized using thermally activated transparency-switching material.

Optics express

Apostoleris H, Stefancich M, Lilliu S, Chiesa M.
PMID: 26367692
Opt Express. 2015 Jul 27;23(15):A930-5. doi: 10.1364/OE.23.00A930.

We present a proof of concept demonstration of a novel optical element: a light-responsive aperture that can track a moving light beam. The element is created using a thermally-activated transparency-switching material composed of paraffin wax and polydimethylsiloxane (PDMS). Illumination...

F360 and F6 Skytaper: SEM evaluation of cleaning efficiency.

Chemistry. 2016 Jan 26;22(5):1779-88. doi: 10.1002/chem.201503431. Epub 2016 Jan 08.

The spin dynamics of Cr8 Mn, a nine-membered antiferromagnetic (AF) molecular nanomagnet, are investigated. Cr8 Mn is a rare example of a large odd-membered AF ring, and has an odd-number of 3d-electrons present. Odd-membered AF rings are unusual and...

Automatic outdoor monitoring system for photovoltaic panels.

EPR approaches to heterogeneous catalysis. The chemistry of titanium in heterogeneous catalysts and photocatalysts.

Journal of magnetic resonance (San Diego, Calif. : 1997)

Morra E, Giamello E, Chiesa M.
PMID: 28579105
J Magn Reson. 2017 Jul;280:89-102. doi: 10.1016/j.jmr.2017.02.008.

Paramagnetic species are often involved in catalytic or photocatalytic reactions occurring at the solid-gas interface of heterogeneous catalysts. In this contribution we will provide an overview of the wealth and breadth of information that can be obtained from EPR...
