Microwave Plasma Enhanced Chemical Vapor Deposition (MWPECVD)

The MWPECVD apparatus is the main facility of this lab and includes:

*ASTeX-type reactor
*Substrate holder (diameter=10 cm)
-tunable height (60 mm)
– heatable and thermally adjustable up to 950°C
* Gas feeding system
*Vacuum system

*Closed-circuit chiller
*IR pyrometer (Williamson Pro 92 40) dual wavelength (2.1 e 2.4
mm) and optical fiber

*He-Ne laser (Melles Griot 30 mWatt) 632.8 nm, PM100D power energy meter and silicon power head (Thorlabs)
*Microwave (MW) generator (2.45 GHz

  • Jam session Nanotec… note di scienza su scala nanometrica

    Lecce, 27 settembre 2019 – ex monastero degli Olivetani “CAR-T: l’alba di una nuova era”  con: Attilio Guarini (IRCCS Istituto Tumori “Giovanni Paolo II” di Bari)  introduce e modera: Marco Ferrazzoli (Ufficio Stampa CNR Roma) a cura di: Gabriella Zammillo 

    Le CAR-T (Chimeric Antigens Receptor Cells-T) sono cellule modificate in laboratorio a partire dai linfociti T. Rappresentano una nuova strategia di cura che sfrutta il sistema immunitario per combattere alcuni tipi di tumore come linfomi aggressivi a grandi cellule e leucemie linfoblastiche acute a cellule B. Il prof Attilio Guarini, ematologo all’Istituto tumori Giovanni Paolo II di Bari, le definisce la “vis sanatrix naturae della antica medicina salernitana”, trattandosi del potenziamento dell’attività citotossica dei linfociti del paziente opportunamente ingegnerizzati per riconoscere e contrastare alcuni tipi di cellule tumorali.
