Nanopolveri e nanotecnologie

Produzione di nanopolveri da Flame Spray Pyrolysis e soluzioni bench-top per la ricerca applicata

Le tecniche comunemente utilizzate per la produzione di nanoparticelle sono molteplici: tra queste, i metodi di sintesi in fase vapore ricoprono un ruolo importante a livello industriale poiché, grazie all’ampia gamma di materiali processabili, al buon controllo sul processo, ai costi sostenibili e alla facilità di scale-up sono ad oggi ampiamente utilizzati per la produzione su larga scala di nanopolveri.

La Flame Spray Pyrolysis (FSP) è un processo in fase gassosa ad alta temperatura per la sintesi di nanopolveri. Rispetto ad altri processi in fase vapore, per la conversione dei precursori non richiede sorgenti di energia esterne quali plasma, laser o camere termo riscaldate, e questo la rende particolarmente economica e scalabile su produzioni industriali.

Tecniche avanzate per la deposizione di film nanostrutturati da fascio di nanoparticelle e loro impiego per la produzione di dispositivi nell’ambito biomedicale

Il cuore tecnologico di Tethis, azienda che opera nel settore delle nano e biotecnologie, sono i processi di sintesi di nanomateriali, in forma di coating e di nanopolveri. In quest’ambito, hanno particolare rilevanza le tecniche di deposizione di film nanostrutturati da fascio supersonico di nanoparticelle (Supersonic Cluster Beam Deposition – SCBD).

Gli impianti di deposizione da fascio supersonico di nanoparticelle sono tipicamente costituiti da una sorgente di nanoparticelle interfacciata ad un sistema da vuoto dove avviene il processo di deposizione vero e proprio. La miscela di gas e nanoparticelle, generata all’interno della sorgente, subisce un’espansione verso la camera a vuoto a cui la sorgente è affacciata. Un ugello a focalizzazione aerodinamica concentra le nanoparticelle a formare un fascio intenso e collimato. Il fascio di nanoparticelle è direzionato sul substrato, dove avviene la crescita del film nanostrutturato. Le energie cinetiche in gioco sono sufficientemente basse da impedire la frammentazione delle nanoparticelle, conservandone di conseguenza la struttura originale. Ciò che si ottiene è un film estremamente poroso e con rugosità superficiale su scala nanometrica, in cui le straordinarie proprietà delle nanoparticelle sono mantenute. Una volta depositati, i film assemblati da nanoparticelle non necessitano di alcun post-processing prima di essere utilizzati nel dispositivo finale.

WMA – Monitoraggio remoto di metalli pesanti in transito sul corpo idrico

Il controllo continuo in linea con conseguente rilevazione in situ di inquinanti, dovrebbe essere uno dei metodi più utilizzati per il monitoraggio dell’ambiente terrestre. Questo tipo di tecnica risulta particolarmente importante ed efficace per l’individuazione delle sostanze inquinanti emergenti, a seguito del progresso industriale e dell’evoluzione dei prodotti chimici utilizzati nell’industria manifatturiera.

SAES ZAO® PUMPS SERIES: A Novel Approach in High Vacuum Systems

Introduction

Getter materials are reactive metals able to chemically sorb active gases in a vacuum environment. They can be classified in two big families: evaporable and non-evaporable getters. The former have been extensively adopted in many industrial applications, like CRTs and lamps, while the latter have drastically changed the way of improving the vacuum levels achievable in vacuum system from medium to extreme high vacuum.

SAES Getters is the repository of the long-standing advanced technology nowadays available on getter materials. In particular in Ultra High Vacuum (UHV) systems compact NEG-based pumps with high pumping speed for hydrogen and active gases have been developed. The list of applications in which SAES NEG Pumps are employed is continuously increasing for the wide range of products offered and their flexibility in adapting to several UHV applications, like Particle Accelerators, Cold Atomic Trap or Surface Science systems.

e-Vision 2

Stability, Accuracy And Speed A Cost Effective Rga For General Purpose Vacuum Analysis

Residual Gas Analysis (RGA) is a routine workhorse tool for any vacuum engineer. The ability to quickly determine the individual gas partial pressures within a vacuum chamber provides a wealth of diagnostic information to help troubleshoot real and virtual leaks, identify components with abnormal out-gassing, identify contaminants and confirm when cryo-pumping and getter systems are close to needing regeneration. The e-Vision 2 RGA is one of a new range of products, from MKS, designed to meet all the traditional requirements for an RGA sensor but with data collection at speeds unachievable with previous generation technologies. The e-Vision 2 RGA is designed to provide maximum value for money. The e-Vision 2 is designed to collect data at millisecond speeds per data point even when measuring data over the full dynamic range of the RGA. This capability has been achieved without sacrificing any of the necessary robustness, reliability and support which have served to make MKS the world leader in RGA products over the widest range of applications — from semiconductor tools or particle accelerators to general industrial applications.

Elucidation of Hydride Interaction Mechanisms with Carbon Nanostructures and the Formation of Novel Nanocomposites

Our investigation of the interaction of metal hydrides and complex metal hydrides with carbon nanostructures (C60, CNT’s, etc.) has demonstrated that these composites can reversibly interact with hydrogen. This interaction leads to new materials in which the desorption/absorption of hydrogen occurs at temperatures and pressures well below the individual precursor components. In particular we focused on the role that C60 played in the reversible hydrogenation of NaAlH4, LiAlH4, and LiBH4. Through a series of spectroscopic analysis of these materials, we determined that a reaction occurs between the complex metal hydride and C60 to produce a metal-doped fullerene. This finding suggested that simple metal hydrides (i.e. LiH) can be used to make large quantities of alkali-doped fullerenes via solvent-assisted mixing and annealing. In the Mx-C60-Hy materials, the active hydrogen storage material resembles a metal-doped fullerane (hydrogenated fullerene).

Specifically designed for Hazardous Species gas phase monitoring, these systems offer unparalleled performance in terms of sensitivity, speed, response time and report generation capabilities. Their capability to monitor virtually any hazardous species makes them the system of choice for plant applications, and ensures compliance with any regulations that may be in place.

5PASCAL-EnviroSafe-Brochure-vacuum-img

Housed within a compact, space saving cabinet gives the user flexibility of the location of the system, and a fully ATEX Zone 1 version is available should user wish to locate the system within the Hazardous area itself.

Up to 64 Individual sample points can be monitored with EnviroSafe, often meaning that an entire plant can be monitored with just one system. All sample points are continuously pumped, ensuring that ‘fresh’ sample arrives at the Mass Spectrometer when that sample stream is selected. The measurement time on individual sample points is user selectable, and can be measured in any desired order. With full, automated unattended operation and integration into the plant control system, together with automated report generation, these systems a suited to many Hazardous area monitoring applications, including:

  •   Vinyl Chloride / DCM Manufacture and pilot plant
  •   Urea / Ammonia plant
  •   Ambient Solvent monitoring (eg Toluene, Styrene, Benzene, etc.)
  •   Chlorinated compounds
  •   Mercaptan and Amines
  •   Gas scrubber monitoring
  •   Enclosed / confined workplaces
  •   CorrosivesReal-time monitoring of up to 64 individual sample species with full alarm generation, the complete process is measured, ensuring that no events are missed. With true on-line monitoring capabilities, EnviroSafe offers a faster, more reliable analysis method than traditional techniques.
