Nanotechnology

Narváez AC, Chiaramonte T, Vicaro KO, Clerici JH, Cotta MA.
PMID: 19843990
Nanotechnology. 2009 Nov 18;20(46):465705. doi: 10.1088/0957-4484/20/46/465705. Epub 2009 Oct 21.

We have studied the equilibrium electrostatic profile of III-V semiconductor nanowires using Kelvin probe force microscopy. Qualitative agreement of the measured surface potential levels and expected Fermi level variation for pure InP and InAs nanowires is obtained from electrical...

A novel study and meta-analysis of the genetic variation of the serotonin transporter promoter in the italian population do not support a large effect on Alzheimer's disease risk.

Int J Alzheimers Dis. 2011;2011:312341. doi: 10.4061/2011/312341. Epub 2011 Jun 02.

Alzheimer's disease (AD) is a neurodegenerative disorder whose clinical onset is mainly characterized by memory loss. During AD progression, behavioral and psychological symptoms of dementia (BPSD) frequently occur. In this paper we evaluated the association between AD and the...

Free-radical addition to ketimines generated in situ. New one-pot synthesis of quaternary alpha-aminoamides promoted by a H2O2/TiCl4-Zn/HCONH2 system.

Organic letters

Pastori N, Greco C, Clerici A, Punta C, Porta O.
PMID: 20695448
Org Lett. 2010 Sep 03;12(17):3898-901. doi: 10.1021/ol1015916.

A free radical multicomponent reaction mediated by an acidic TiCl(4)-Zn/H(2)O(2) system allows the assembly of an amine, a ketone, and formamide in one pot, affording instant access to quaternary alpha-amino acid derivatives.

Disarming dendritic cells: a tumor strategy to escape from immune control?.

Expert review of clinical immunology

Della Bella S, Clerici M, Villa ML.
PMID: 20477683
Expert Rev Clin Immunol. 2007 May;3(3):411-22. doi: 10.1586/1744666X.3.3.411.

Although the immune system is clearly capable of recognizing and eliminating tumor cells, it usually fails to provide adequate protective antitumor responses. It is becoming increasingly clear that modifications of dendritic cells (DCs), which are central regulators of immune...

Spectrum to distance mapping via nonlinear Airy pulses.

Optics letters

Hu Y, Li M, Bongiovanni D, Clerici M, Yao J, Chen Z, Azaña J, Morandotti R.
PMID: 23381444
Opt Lett. 2013 Feb 01;38(3):380-2. doi: 10.1364/OL.38.000380.

We theoretically and experimentally study the phenomena related to self-phase modulation of Airy pulses in fibers. During nonlinear evolution, most spectral components of the Airy pulses concentrate into one or two peaks for normal and anomalous dispersion, respectively. The...

Mono thiomalonates as thioester enolate equivalents--enantioselective 1,4-addition reactions to nitroolefins under mild conditions.

Organic & biomolecular chemistry

Clerici P, Wennemers H.
PMID: 22068641
Org Biomol Chem. 2012 Jan 07;10(1):110-3. doi: 10.1039/c1ob06638b. Epub 2011 Nov 08.

Mono thiomalonates (MTMs) are introduced as thioester enolate equivalents. Asymmetric organocatalyzed conjugate addition reactions to nitroolefins proceed under mild conditions to afford synthetically useful γ-nitrothioesters with excellent yields and enantioselectivities.

A novel data mining system points out hidden relationships between immunological markers in multiple sclerosis.

Immunity & ageing : I & A

Gironi M, Saresella M, Rovaris M, Vaghi M, Nemni R, Clerici M, Grossi E.
PMID: 23305498
Immun Ageing. 2013 Jan 10;10(1):1. doi: 10.1186/1742-4933-10-1.

BACKGROUND: Multiple Sclerosis (MS) is a multi-factorial disease, where a single biomarker unlikely can provide comprehensive information. Moreover, due to the non-linearity of biomarkers, traditional statistic is both unsuitable and underpowered to dissect their relationship. Patients affected with primary...

Counterpropagating frequency mixing with terahertz waves in diamond.

Optics letters

Clerici M, Caspani L, Rubino E, Peccianti M, Cassataro M, Busacca A, Ozaki T, Faccio D, Morandotti R.
PMID: 23454954
Opt Lett. 2013 Jan 15;38(2):178-80. doi: 10.1364/OL.38.000178.

Frequency conversion by means of Kerr nonlinearity is one of the most common and exploited nonlinear optical processes in the UV, visible, IR, and mid-IR spectral regions. Here we show that wave mixing of an optical field and a...

Hawking radiation from ultrashort laser pulse filaments.

Physical review letters

Belgiorno F, Cacciatori SL, Clerici M, Gorini V, Ortenzi G, Rizzi L, Rubino E, Sala VG, Faccio D.
PMID: 21231233
Phys Rev Lett. 2010 Nov 12;105(20):203901. doi: 10.1103/PhysRevLett.105.203901. Epub 2010 Nov 08.

Event horizons of astrophysical black holes and gravitational analogues have been predicted to excite the quantum vacuum and give rise to the emission of quanta, known as Hawking radiation. We experimentally create such a gravitational analogue using ultrashort laser...

Collapse arrest in instantaneous Kerr media via parametric interactions.

Physical review letters

Pasquazi A, Peccianti M, Clerici M, Conti C, Morandotti R.
PMID: 25302888

We demonstrate, theoretically and experimentally, that a four-wave mixing parametric interaction is able to arrest the collapse of a two-dimensional multicolor beam in an instantaneous Kerr medium. We consider two weak idlers interacting via a third order nonlinearity with...
