PMID: 27356278
Chemistry. 2016 Sep 12;22(38):13705-14. doi: 10.1002/chem.201601383. Epub 2016 Jun 29.

A 3D metal-organic framework (MOF) having single-molecule magnet (SMM) linkers was prepared in crystalline form by using a tetrairon(III) complex functionalised with two divergent pyridyl groups, namely [Fe4 (pPy)2 (dpm)6 ] (1; H3 pPy=2-(hydroxymethyl)-2-(pyridin-4-yl)propane-1,3-diol, Hdpm=dipivaloylmethane). Reaction of 1 with...

Exploring the Role of Theory of Mind in Moral Judgment: The Case of Children with Autism Spectrum Disorder.

Frontiers in psychology

This paper adds to the growing research on moral judgment (MJ) by considering whether theory of mind (ToM) might foster children's autonomous MJ achievement. A group of 30 children with autism spectrum disorder (ASD) was compared in MJ and...

Spectroscopic signatures of a bandwidth-controlled Mott transition at the surface of 1T-TaSe2.

Physical review letters

Perfetti L, Georges A, Florens S, Biermann S, Mitrovic S, Berger H, Tomm Y, Höchst H, Grioni M.
PMID: 12731984
Phys Rev Lett. 2003 Apr 25;90(16):166401. doi: 10.1103/PhysRevLett.90.166401. Epub 2003 Apr 22.

High-resolution angle-resolved photoemission data show that a metal-insulator Mott transition occurs at the surface of the quasi-two-dimensional compound 1T-TaSe2. The transition is driven by the narrowing of the Ta 5d band induced by a temperature-dependent modulation of the atomic...

Strongly coupled optical phonons in the ultrafast dynamics of the electronic energy and current relaxation in graphite.

Physical review letters

Kampfrath T, Perfetti L, Schapper F, Frischkorn C, Wolf M.
PMID: 16383946
Phys Rev Lett. 2005 Oct 28;95(18):187403. doi: 10.1103/PhysRevLett.95.187403. Epub 2005 Oct 26.

Ultrafast charge carrier dynamics in graphite has been investigated by time-resolved terahertz spectroscopy. Analysis of the transient dielectric function and model calculations show that more than 90% of the initially deposited excitation energy is transferred to a few strongly...

Nonlinear analyses of cell proliferation in the central nervous system reveal stochastic and deterministic components.

Conf Proc IEEE Eng Med Biol Soc. 2004;2004:857-60. doi: 10.1109/IEMBS.2004.1403293.

This paper analyzes the dynamics of cell proliferation in the developing central nervous system. Three different algorithms, Fano factor, Allan factor and detrended fluctuations analysis, are used to estimate de scaling exponent of space numerical series obtained by recording...

Chem Commun (Camb). 2007 Jan 28;(4):350-2. doi: 10.1039/b612002d. Epub 2006 Nov 23.

A porous single-crystal collects xenon atoms from the gas phase and orients them macroscopically, as highlighted by hyperpolarized xenon NMR.

Reading optimally builds on spoken language: implications for deaf readers.

Journal of deaf studies and deaf education

Perfetti CA, Sandak R.
PMID: 15454516
J Deaf Stud Deaf Educ. 2000;5(1):32-50. doi: 10.1093/deafed/5.1.32.

Reading is not merely "language by eye." Rather, it builds fundamentally on primary language processes. For hearing readers, this means that spoken language processes, including phonological processes, are critical to high achievement in reading. We examine the implications of...

Evidence for bone mass and body fat distribution relationship in postmenopausal obese women.

Archives of gerontology and geriatrics

Tarquini B, Navari N, Perfetto F, Piluso A, Romano S, Tarquini R.

Arch Gerontol Geriatr. 1997 Jan-Feb;24(1):15-21. doi: 10.1016/s0167-4943(96)00723-6.

The measurement of bone mass, a reliable predictor of osteoporotic fractures, in obese subjects has yielded conflicting results and bone mass has been reported to be elevated, normal or decreased. These observations indicate that factors other than body weight...

Ultrafast electron relaxation in superconducting Bi(2)Sr(2)CaCu(2)O(8+delta) by time-resolved photoelectron spectroscopy.

Physical review letters

Perfetti L, Loukakos PA, Lisowski M, Bovensiepen U, Eisaki H, Wolf M.

Phys Rev Lett. 2007 Nov 09;99(19):197001. doi: 10.1103/PhysRevLett.99.197001. Epub 2007 Nov 09.

Time-resolved photoelectron spectroscopy is employed to study the dynamics of photoexcited electrons in optimally doped Bi{2}Sr{2}CaCu{2}O{8+delta} (Bi-2212). Hot electrons thermalize in less than 50 fs and dissipate their energy on two distinct time scales (110 fs and 2 ps)....
