Terahertz and mid-infrared plasmons in three-dimensional nanoporous graphene.

Nature communications

D'Apuzzo F, Piacenti AR, Giorgianni F, Autore M, Guidi MC, Marcelli A, Schade U, Ito Y, Chen M, Lupi S.
PMID: 28345584
Nat Commun. 2017 Mar 27;8:14885. doi: 10.1038/ncomms14885.

Two-dimensional (2D) graphene emerged as an outstanding material for plasmonic and photonic applications due to its charge-density tunability, high electron mobility, optical transparency and mechanical flexibility. Recently, novel fabrication processes have realised a three-dimensional (3D) nanoporous configuration of high-quality...

Undifferentiated Pleomorphic Sarcoma and the Importance of Considering the Oncogenic and Immune-Suppressant Role of the Human T-Cell Lymphotropic Virus Type 1: A Case Report.

Frontiers in oncology

Lupo S, Berini C, Cánepa C, Santini Araujo E, Biglione M.
PMID: 28596939
Front Oncol. 2017 May 24;7:91. doi: 10.3389/fonc.2017.00091. eCollection 2017.

INTRODUCTION: Soft-tissue sarcomas account for 0.7% of all malignant tumors, with an incidence rate of 3 per 100,000 persons/year. The undifferentiated pleomorphic sarcoma (UPS) with giant cells, a high grade tumor of soft tissue, is very unusual, especially in...

Impact of Vitamin D deficiency on subclinical carotid atherosclerosis: a pooled analysis of cohort studies.

The Journal of clinical endocrinology and metabolism

Lupoli R, Vaccaro A, Ambrosino P, Poggio P, Amato M, Di Minno MN.
PMID: 28609831
J Clin Endocrinol Metab. 2017 Jul;102(7):2146-2153. doi: 10.1210/jc.2017-00342. Epub 2017 May 09.

CONTEXT: Vitamin D deficiency patients have an increased cardiovascular (CV) morbidity and mortality. Carotid intima-media thickness (IMT) and carotid plaques are markers of subclinical atherosclerosis and predictors of CV events.OBJECTIVE: To perform a meta-analysis of studies evaluating the impact...

Proteinuria as a surrogate marker for renal outcome: are we there yet?.

Kidney international

Avasare RS, Radhakrishnan J.
PMID: 26649661
Kidney Int. 2015 Dec;88(6):1228-1230. doi: 10.1038/ki.2015.301.

Observational studies in glomerular diseases suggest that proteinuria reduction translates to improved outcomes. Because of a dearth of high-quality studies supporting this association, proteinuria is not universally recognized as a surrogate end point. Barbour et al. report on the...

Brain Plasticity Effects of Neuromodulation Against Multiple Sclerosis Fatigue.

Frontiers in neurology

Tecchio F, Cancelli A, Cottone C, Ferrucci R, Vergari M, Zito G, Pasqualetti P, Filippi MM, Ghazaryan A, Lupoi D, Smits FM, Giordani A, Migliore S, Porcaro C, Salustri C, Rossini PM, Priori A.

Front Neurol. 2015 Jul 03;6:141. doi: 10.3389/fneur.2015.00141. eCollection 2015.

RATIONALE: We recently reported on the efficacy of a personalized transcranial direct current stimulation (tDCS) treatment in reducing multiple sclerosis (MS) fatigue. The result supports the notion that interventions targeted at modifying abnormal excitability within the sensorimotor network could...

Infrared evidence of a Slater metal-insulator transition in NaOsO₃.

Scientific reports

Vecchio IL, Perucchi A, Di Pietro P, Limaj O, Schade U, Sun Y, Arai M, Yamaura K, Lupi S.
PMID: 24141899
Sci Rep. 2013 Oct 21;3:2990. doi: 10.1038/srep02990.

The magnetically driven metal-insulator transition (MIT) was predicted by Slater in the fifties. Here a long-range antiferromagnetic (AF) order can open up a gap at the Brillouin electronic band boundary regardless of the Coulomb repulsion magnitude. However, while many...

Axial Ligand exchange in chiral macrocyclic ytterbium(III) complexes.

Inorganic chemistry

Lisowski J, Ripoli S, Di Bari L.
PMID: 14966974
Inorg Chem. 2004 Feb 23;43(4):1388-94. doi: 10.1021/ic0353918.

We investigate the role of axial ligands on the near-IR-optical and paramagnetic NMR spectra of the complex [YbL](+3) where L is the stereodefined enantiopure chiral macrocycle (L = hexaazapentacyclo[25.3.1.1(12,24).0(4,9).0(19,24)]dotriaconta-1(31),2,10,12,14,16(32),17,25,27,29-decaene). The conformation in solution of the lanthanide complex is characterized...

Determination of firing distance. Lead analysis on the target by atomic absorption spectroscopy (AAS).

Journal of forensic sciences

Gagliano-Candela R, Colucci AP, Napoli S.
PMID: 18366562
J Forensic Sci. 2008 Mar;53(2):321-4. doi: 10.1111/j.1556-4029.2008.00668.x.

This paper reports a method for the determination of the firing distance. Atomic absorption spectroscopy (AAS) was used to determine the lead (Pb) pattern around bullet holes produced by shots on test targets from the gun. Test shots were...

Pressure dependence of the charge-density-wave gap in rare-earth tritellurides.

Physical review letters

Sacchetti A, Arcangeletti E, Perucchi A, Baldassarre L, Postorino P, Lupi S, Ru N, Fisher IR, Degiorgi L.

Phys Rev Lett. 2007 Jan 12;98(2):026401. doi: 10.1103/PhysRevLett.98.026401. Epub 2007 Jan 11.

We investigate the pressure dependence of the optical properties of CeTe3, which exhibits an incommensurate charge-density-wave (CDW) state already at 300 K. Our data are collected in the midinfrared spectral range at room temperature and at pressures between 0...

Temperature dependence of the optical spectral weight in the cuprates: role of electron correlations.

Physical review letters

Toschi A, Capone M, Ortolani M, Calvani P, Lupi S, Castellani C.
PMID: 16197238
Phys Rev Lett. 2005 Aug 26;95(9):097002. doi: 10.1103/PhysRevLett.95.097002. Epub 2005 Aug 24.

We compare calculations based on the dynamical mean-field theory of the Hubbard model with the infrared spectral weight W(Omega,T) of La(2-x)SrxCuO4 and other cuprates. Without using fitting parameters we show that most of the anomalies found in W(Omega,T) with...

Nature communications

Lupi S, Baldassarre L, Mansart B, Perucchi A, Barinov A, Dudin P, Papalazarou E, Rodolakis F, Rueff JP, Itié JP, Ravy S, Nicoletti D, Postorino P, Hansmann P, Parragh N, Toschi A, Saha-Dasgupta T, Andersen OK, Sangiovanni G, Held K, Marsi M.
PMID: 21045823
Nat Commun. 2010 Nov 02;1:105. doi: 10.1038/ncomms1109.

V(2)O(3) is the prototype system for the Mott transition, one of the most fundamental phenomena of electronic correlation. Temperature, doping or pressure induce a metal-to-insulator transition (MIT) between a paramagnetic metal (PM) and a paramagnetic insulator. This or related...
