Descriviamo un esperimento progettato per sondare l'elettronico danno indotto in nanocristalli di Buckminsterfullerene (C60) di impulsi a femtosecondi intenso, dei raggi x. L'esperimento ha trovato che, sorprendentemente, piuttosto che essere stocastico, i raggi x hanno indotto electron dynamics in C60 sono altamente correlati, che si estendono su centinaia di celle all'interno di cristalli1.

Questo documento fornisce una breve panoramica degli sforzi in corso presso il laboratorio di ricerca dell'esercito sul trattamento dei metalli nanocristallini massa con un'enfasi sulle metodologie utilizzate per la produzione di polveri di metallo romanzo.

Descriviamo un setup beamline significato per effettuare la mappatura di microdiffrazione di fluorescenza e raggi x rapida radiografia bidimensionale di campioni singoli di cristallo o polvere utilizzando Laue (policromatica radiazione) o diffrazione da polveri (radiazione monocromatica). Le mappe risultanti danno informazioni sul ceppo, orientamento, distribuzione di fase e deformazione plastica.

Questo protocollo presenta una procedura dettagliata per preparare criocampioni biologici per esperimenti di spettroscopia di assorbimento dei raggi X basati su sincrotrone. Descriviamo tutti i passaggi necessari per ottimizzare la preparazione del campione e la crioconservazione con esempi del protocollo con cellule tumorali e fitoplancton. Questo metodo fornisce uno standard universale di crio-preparazione del campione.

Preparazione di campioni biologici per la speciazione a temperatura criogenica mediante spettroscopia di assorbimento a raggi X ad alta risoluzione

Questo metodo di speciazione di redox di ferro si basa sulla spettrometria di massa plasmatica accoppiata con elettroforesi capillare con impilamento del campione combinato con analisi breve in una sola esecuzione. Il metodo analizza rapidamente e fornisce bassi limiti di quantificazione per le specie di redox di ferro in una vasta gamma di tessuti e campioni di biofluidi.

Forniamo una descrizione generale dei metodi quantitativi di microanalisi per stimare le occupazioni del sito delle impurità e dei loro stati chimici sfruttando i fenomeni di canalizzazione elettronica in condizioni di oscillazione del fascio di elettroni incidente, che estraggono in modo affidabile informazioni da specie minoritarie, elementi leggeri, posti vacanti di ossigeno e altri difetti punti / linea / planari.

Qui, utilizziamo uno stabilizzatore polimerico per preparare sospensioni metallo-organica (MOF) che mostrano una dispersione marcatamente ridotta nei loro spettri di assorbimento transitorio e dello stato fondamentale. Con queste sospensioni MOF, il protocollo fornisce varie linee guida per caratterizzare spettroscopicamente i MOF per produrre dati interpretabili.
