Xiraphi N, Georgalaki M, Rantsiou K, Cocolin L, Tsakalidou E, Drosinos EH.
PMID: 22063322
Meat Sci. 2008 Oct;80(2):194-203. doi: 10.1016/j.meatsci.2007.11.020. Epub 2007 Dec 03.

Leuconostoc mesenteroides E131, isolated from Greek traditional fermented sausage, prepared without the addition of starters, produces a bacteriocin which is active against the pathogen Listeria monocytogenes. The bacteriocin was purified by 50% ammonium sulphate precipitation, cation exchange, and reverse-phase...

Social science & medicine (1982)

Georgalakis J.
PMID: 32143087
Soc Sci Med. 2020 Feb 13;250:112851. doi: 10.1016/j.socscimed.2020.112851. Epub 2020 Feb 13.

This paper investigates whether the inclusion of social scientists in the UK policy network that responded to the Ebola crisis in Sierra Leone (2013-16) was a transformational moment in the use of interdisciplinary research. In contrast to the existing...

Microstructure and mechanical behavior of metallic glass fiber-reinforced Al alloy matrix composites.

Scientific reports

Wang Z, Georgarakis K, Nakayama KS, Li Y, Tsarkov AA, Xie G, Dudina D, Louzguine-Luzgin DV, Yavari AR.
PMID: 27067824
Sci Rep. 2016 Apr 12;6:24384. doi: 10.1038/srep24384.

Metallic glass-reinforced metal matrix composites are an emerging class of composite materials. The metallic nature and the high mechanical strength of the reinforcing phase offers unique possibilities for improving the engineering performance of composites. Understanding the structure at the...

Crystallization of Ti33Cu67 metallic glass under high-current density electrical pulses.

Nanoscale research letters

Dudina DV, Mali VI, Anisimov AG, Lomovsky OI, Korchagin MA, Bulina NV, Neklyudova MA, Georgarakis K, Yavari AR.
PMID: 21871070
Nanoscale Res Lett. 2011 Aug 26;6:512. doi: 10.1186/1556-276X-6-512.

We have studied the phase and structure evolution of the Ti33Cu67 amorphous alloy subjected to electrical pulses of high current density. By varying the pulse parameters, different stages of crystallization could be observed in the samples. Partial polymorphic nanocrystallization...

Map of Care: 10 smart tools for the evaluation of senior care facilities.

Alzheimer's & dementia : the journal of the Alzheimer's Association

PMID: 34971252
Alzheimers Dement. 2021 Dec;17:e057548. doi: 10.1002/alz.057548.

BACKGROUND: Many senior care facilities (assisted living, nursing homes, memory care) are of average quality. There is lack of reliable and impartial information on care facilities. Furthermore, most people do not have the specific knowledge to evaluate their various...

Crystallization during bending of a Pd-based metallic glass detected by x-ray microscopy.

Physical review letters

Yavari AR, Georgarakis K, Antonowicz J, Stoica M, Nishiyama N, Vaughan G, Chen M, Pons M.
PMID: 23002757
Phys Rev Lett. 2012 Aug 24;109(8):085501. doi: 10.1103/PhysRevLett.109.085501. Epub 2012 Aug 21.

Without the availability of slip systems and dislocation glide as in crystalline materials, metallic glasses resist irreversible deformation to elastic strains of 2% or more before undergoing heterogeneous plastic flow via the formation of shear bands. Observation of crystallite...

Age-Dependent Asymmetry of Wrist Position Sense Is Not Influenced by Stochastic Tactile Stimulation.

Front Hum Neurosci. 2020 Mar 03;14:65. doi: 10.3389/fnhum.2020.00065. eCollection 2020.

Stochastic stimulation has been shown to improve movement, balance, the sense of touch, and may also improve position sense. This stimulation can be non-invasive and may be a simple technology to enhance proprioception. In this study, we investigated whether...

Probing heat generation during tensile plastic deformation of a bulk metallic glass at cryogenic temperature.

Scientific reports

Brennhaugen DDE, Georgarakis K, Yokoyama Y, Nakayama KS, Arnberg L, Aune RE.

Sci Rep. 2018 Nov 05;8(1):16317. doi: 10.1038/s41598-018-34681-4.

Despite significant research efforts, the deformation and failure mechanisms of metallic glasses remain not well understood. In the absence of periodic structure, these materials typically deform in highly localized, thin shear bands at ambient and low temperatures. This process...
