BSD Medical Corp. introduces new use of MRI to treat cancer

BSD Medical Corp. has introduced a radical new use of MRI to treat cancer called the BDS-2000/3D/MR. The hybrid system was developed through joint efforts of BSD Medical Corp., Charite Medical School in Berlin and Siemens Medical Systems.

Study reports benefits of cryosurgery with chemotherapy

A study published in the May 14 British Journal of Cancer reported that the synergistic effect of pairing cryosurgery (freezing cells to destroy them) and chemotherapy may lead to a powerful new form of cancer treatment that targets malignant cells while leaving healthy tissue unharmed.

Superconducting dipole magnets arrive on time for installation in LHC

The anticipated 1,232 superconducting dipole magnets arrived on time for installation in CERN's Large Hadron Collider (LHC) this fall.

Air Products and Linde to supply cryogenic equipment to ILC

Air Products and Linde signed a Teaming Agreement to pursue refrigeration services for the proposed International Linear Collider (ILC). They hope to work together to provide, operate and maintain the cryogenic equipment for the ILC.

Chart Energy and Chemicals extends its BAHX product line

Chart Industries, Inc. announced that its wholly-owned subsidiary Chart Energy and Chemicals, Inc. has extended its Brazed Aluminum Heat Exchanger (BAHX) product line with the development and installation of an advanced new Welded Plate Heat Exchanger (WPX).

Latest in Defining Cryogenics

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
