The application of ESEM to biological samples

open access: yesJournal of Physics: Conference Series, 2010
The Environmental Scanning Electron Microscope (ESEM) differs from a conventional SEM in that a differential pumping system maintains a pressure of gas (typically H2O) in thespecimen chamber whilst the gun remains at high vacuum. Ionizing collisions between electrons and these gas molecules create positive ions which drift down onto the sample ...

Using Cu2+‐Centered Complexes as Glue: Two New Layered Polyoxotantalates Based on the Interconnection of the {Ta6O19} Moiety

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Layered structures of polyoxotantalates generated by different connection modes of the dimeric {(Cu(dien))2Cu(Ta6O19)2} unit. Applying the three different solutions [Cu(dien)]2+ in DMSO/H2O, acetonitrile, and [Ta6O19]6‐/H2O in a layering approach, the two new polyxotantalates [Cu(dien)]5{(Cu(dien)(H2O)2)Cu(Ta6O19)2}·DMSO·32 H2O (I) and K2[(Cu(dien))6 ...

Macroporous silicon membranes as electron and x-ray transmissive windows [PDF]

open access: yes, 2004
Macroporous silicon membranes are fabricated whose pores are terminated with 60 nm thin silicon dioxide shells. The transmission of electrons with energies of 5 kV-25 kV through these membranes was investigated reaching a maximum of 22% for 25 kV ...

Market Design in a Weather‐Dependent and Distributed Electricity System: Lessons From the 2025 NEM Review

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Australia's National Electricity Market (NEM) is undergoing a rapid transition to a weather‐dependent and increasingly distributed system. This article draws on the 2025 NEM Review to examine whether the core energy‐only market design remains fit for purpose.

Recovery and reuse of discontinuous carbon fibres by solvolysis: Realignment and properties of remanufactured materials [PDF]

open access: yes, 2016
Discontinuous carbon fibre tows were recovered after solvolysis of an aeronautic type composite made with RTM6 epoxy resin. A Sohxlet extraction method was used to quantify the organic residue on the fibre tows and showed that less than 3 wt% was ...

A Newly Discovered Tablet‐Making Facility in Nineveh: Insights From Scientific Analysis

open access: yesArchaeometry, EarlyView.
ABSTRACT This paper addresses the question of tablet technology in the Neo‐Assyrian capital city of Nineveh. Recent excavations in the lower town of Nineveh by the Iraqi–Italian Archaeological Expedition uncovered an exceptional assemblage of more than 200 tablets from an elite residence that appears to have included a scriptorium.

Improvements for imaging ceramics sintering in situ in ESEM.

open access: yesJournal of microscopy, 2011
Sintering of green samples of alumina produced by ice-templating was followed in situ in an environmental scanning electron microscope (ESEM) up to temperatures as high as 1375°C. These alumina samples with well-defined architectures are of great interest in the field of materials science due to their high specific strength (especially in compression),
