高圧粉末X線回折実験と強度解析 High Pressure X-ray Powder Diffraction Experiments and Intensity Analyses |
藤久裕司 青木勝敏 Hiroshi FUJIHISA Katsutoshi AOKI |
Recent x-ray powder diffraction techniques
with a diamond anvil cell and an image
plate
are briefly reviewed. Powder preparations
and diffraction measurements should
be done
with care, especially for high pressure
experiments,
to make later intensity analyses reliable.
High quality intensity data are applicable
not only to structure analyses but
to electron
density analyses. [DAC, image plate, x-ray powder diffraction, Rietveld method, maximum entropy method] |

永田 潔文 Kiyofumi NAGATA |
In this article, the techniques for Raman
spectroscopy with a diamond anvil cell
(DAC)
are described. After the brief descriptions
of Raman spectroscopy and the role
of pressure
in it, the instrumentation necessary
to measure
Raman spectra at high pressure and
the techniques
for obtaining good Raman spectra are
presented.
These include techniques for sample
preparation,
optical alignment, reduction of luminescence
from diamonds and selection of a laser.

Infrared(IR) spectroscopy is a very important
field of study of rotational and vibrational
motions of a molecule. Recent developments
in micro FT-IR spectrometer enable
us to
measure IR spectra of very small (micron
order) samples. In this article the
experimental

清水 克哉 Katsuya SHIMIZU |
In this section, our recent development of
low temperature technique arranged for DAC
is reviewed. DAC is now a very powerful device
to achieve high-pressures and small enough
to connect with low temperature equipments.
The development is mainly devorted to electrical
resistance or magnetic susceptibility measurements
under high pressures and low temperatures,
up to 100GPa and down to mK region, and the
ditailes are described. [DAC, low temperature, high pressure, pressure determination, electrical resistance, magnetic susceptibility, dilution refrigerator] |

高圧食品開発物語(その4) 高圧処理による低菌化緑色野菜の開発 Story of Development of High-Pressure Processed Foods, Part 4 |
山崎 彬 杵淵 美倭子 Akira YAMAZAKI Miwako KINEFUCHI |
Green vegetables are a very important nutritional
source for maintaining our health. However,
because the chlorophyll converts to pheohytin
with the fading of its green color when subjected
to heat sterilization, it has long been a
dream to store green vegetables for long
periods of time. In our method, sterilization
and inactivation of enzymes are carried out
by a combination of high pressure and heat
in an effort to develop green vegetables
with superior storage characteristics. As
a result, we have succeeded in reducing the
micro-organism content in spinach, field
peas and broccoli to an acceptable level
in the practical use by the application of
high pressure of 400 MPa at 55℃ for 10 min. [high-pressure processed foods,chlorophyll,germ-free green vegetables,sterilization] |
