The Beryllium Thread

[Simplex3]

I'm putting this in here so that it won't hang around the top of the lounge while I cut and paste information in to post after post.

This is part of my ongoing offseaon attempt to get us ranked on the first page of some search engine(s) when nerds search for "beryllium".

Before you PM me with "Why?", the answer is simply that I am sitting around reading log files at work and cutting and pasting into this thread requires absolutely NO mental stress.

Ongoing programs subject to review by the Be IRB are:

All related research activities;
The Former Beryllium Workers Medical Surveillance Program (see website for list of DOE sites); and
The beryllium screening component of the Former Workers Program (see website for list of DOE sites).

[Bugeater]

The Be IRB, funded by SC and EH, will operate as a subcommittee of the Oak Ridge Site-wide IRB (ORSWIRB). It will serve as DOE's IRB of record for satisfying the DOE and Department of Health and Human Services human subjects protection requirements for all research protocols that include or are explicitly funded as Be research. When there is an IRB at a DOE site (site IRB), the input of the site IRB will be solicited prior to the Be IRB review of any Be research protocol for the site. As questions or uncertainties arise regarding the applicability of human subjects protection regulations, the final resolution will be determined by SC, which holds this responsibility within the Department.* Procedures for the Central Be Institutional Review Board may be found at below.

A mismatch between problems and solutions is crippling many of the network applications being implemented today. Most existing network protocols and software products were designed for an interactive client-server computing model, and they often fail to meet the needs of an increasingly automated, peer-to-peer world. Adeptech Systems, Inc. (ASI) has embarked on a research and development project, named Beryllium, based on its extensive past experience with creating successful secure data interchange and messaging applications.

[Bugeater]

Beryllium is designed to provide the glue to hold network applications together
to enable applications to exchange data securely, efficiently, and transparently, in an automated and peer-to-peer fashion, while leveraging and extending existing applications. It is also designed to enable control, prioritization, monitoring, and tracking of data transfers between applications, whether they are on the same machine or whether they are in separate organizations. A number of superficially similar network application frameworks exist, but none of them combines Beryllium's combination of efficiency, flexibility, and security; and only Beryllium has been optimized for secure data transfers which pass through untrusted networks such as the Internet.

[Bugeater]

ASI's plans for Beryllium are to release it as open source software, and to leverage our leadership and knowledge in this area into customization and consulting business. At present we have extensive design work completed, and have some elements of a prototype implementation.

Beryllium has long been recognized as the ideal material for grids for analytical electron microscopy. The low atomic number of beryllium assures the microscopist of EDS spectra which are both free from annoying characteristic x-ray peaks and low in Bremsstrahlung background radiation. SPI Supplies has switched to a new, higher purity beryllium metal than previously for beryllium grid production, characteristic x-ray peaks from impurities in the metal are virtually absent from grid bar control spectra. These grids, which are all 25µm thick area available as both square mesh and slot designs. Beryllium metal is difficult to etch, and these grids do not have grid bars that are thin and smooth, or the large open areas of our other grids made by electro deposited techniques. Important note: Not all beryllium TEM grids are the same.

A few words about the origin of the SPI Supplies Brand of Beryllium Grids:
Because of the uniqueness of beryllium, and the safety concerns when the metal is processed, there is not a large number of firms offering beryllium. Indeed the number of such firms processing and refining beryllium metal in the world could be counted on half the fingers of one hand. The leading firm is, by far, Brush Wellman Electrofusion. Most beryllium fabricators use as their starting material high purity beryllium rod, strip or foil that has been produced by Brush Wellman. We do have available beryllium starting material from sources outside of the USA, however the claimed purity is never as high as is claimed, and in any case, fall far short of the purity specifications of the Brush Wellman supplied material. The TEM grids being offered by SPI Supplies have been fabricated from the highest purity available from Brush Wellman. We want to make that point because there is just no comparison between these fine outstanding grids produced from Brush Wellman starting material and grids produced from material of alternative origins.

All SPI Beryllium grids are 25µm thick. Packaged in a green dial-a-grid box.

For FIB and Ion Milling applications:
SPI Supplies can now offer "beryllium half grids".

Beryllium

Fly you to the stars,
we said we would.
Kill us all,
you said you could.
So find we did
another way;
and here on earth,
you do stay.

Don't eat beryllium. It leaves an aftertaste of questionability.

Make sure that you fully understand how this diagram relates to the dimer shown in the previous diagram.

Why isn't beryllium chloride ionic?

[Simplex3]

Beryllium has quite a high electronegativity compared with the rest of the Group. That means that it attracts a bonding pair of electrons towards itself more strongly than magnesium and the rest do.
