Happy International Bath Day ! 🛁🧼🚿
(June 14)
Hair conditioner, fresh cream, and agar jelly were investigated using cryo-SEM technique. Lamella structure of hair conditioner, air bubbles and fat globules in fresh cream, and network structure of agar jelly were clearly observed at cryogenic temperature.

Freeze-fracture TEM of Cosmetic Gel
Freeze-fracture technique was used to examine cosmetic gel. The sample was quickly frozen, fractured, and vapor-deposited with platinum and carbon. Freeze-fracture technique is effective in observing the network structure of gel and the distribution of moisturizing ingredients.

It’s National Ballpoint Pen Day ! 🖊🗒️📓🖊
(June 10)
Ballpoint pen
Ballpoint pens contain an oil-based ink.
This ink is slightly thicker than normal and does not bleed easily in water. At the tip of the pen is a very small ball.

“Coral reefs”
Coral reefs spread in the sea. These pictures remind us beautiful sight of shiny blue southern ocean are SE (Secondary Electron) images of Si-W-O whiskers using a STEM (Scanning Transmission Electron Microscope) (Fig.a). The whiskers with the size of several hundred nano meters grow all around (Fig.b). One of whiskers has a prism-shape and another has steps of several nano meters on the surface (Fig.c, d). The bright band which extends from the lower left to upper right in the image looks like the sunlight through the seawater.
These works were presented at the "photo contest" hosted by the Japanese Society of Microscopy.

SEM-EDS analysis of Marine Microplastics (MPs)
Microplastics (MPs) fragments collected from a sandy beach were investigated by Variable Pressure SEM. Cross sectional images showed fine inorganic particles with diameters of 0.1 to 1 μm contained in the resin. Compositional analysis result suggested that the MPs is rusted stainless steel (iron-chromium alloy) with anticorrosive paint (chrome yellow).

Automated virus particle analysis of negatively stained norovirus
36 TEM images of negatively stained norovirus were automatically acquired using Image Navigation function. Designated areas of a whole grid image or a low magnification image can be automatically imaged at a specified magnification. Particle size distribution of 4096 collected virus particles was measured by batch processing of 36 images using an image processing software, Image Pro Premier.

Happy World Environment Day ! 🌱🌳🌎🌍🌏🌅

“Reducing CO2 Emissions in Manufacturing Facilities with an Eco-Design Electron Microscope”
It is no exaggeration to say that providing society with products that are in harmony with the environment has become the responsibility of manufacturing companies in recent years. Reducing environmental impact throughout the entire product life cycle—from procurement of raw materials to manufacturing, distribution, use, disposal and recycling—contributes to solving global issues such as climate change, scarcity of water resources, and environmental pollution caused by waste.
Hitachi High-Tech is promoting eco-design throughout the entire Group, with the aim of creating designs that are considerate of the environment right from the initial stages of product development, and quantitatively evaluating their environmental impact through LCA (Life Cycle Assessment).
One of the key elements of this initiative is our global target of reducing CO2 emissions, which is required to achieve carbon neutrality by 2050. Hitachi High-Tech has been promoting manufacturing with lower CO2 emissions by leveraging its unique technologies and expertise cultivated in the course of manufacturing over the years.
As an example of eco-design, we will look at the High-Precision Electron Beam Metrology System GT2000, the latest model of Hitachi High-Tech's flagship CD-SEMs. A CD-SEM is a metrology tool that measures the quality of semiconductor device patterns formed on silicon wafers at the nanometer-level, making it indispensable to semiconductor manufacturers all around the world.
The latest CD-SEMs possess processing capabilities increased by 25% compared to previous models, while also having reduced CO2 emissions by 50% when compared to our standard product from FY2010. By achieving both improved measurement performance and greatly reduced environmental impact, Hitachi High-Tech is providing robust support to the rapidly expanding semiconductor market that is being driven by advances in generative AI, autonomous driving, next-generation communications and quantum technologies.

Happy Oral Health Month ! 😬🦷🪥👄

Cross-sectional SEM of a permanent tooth (wisdom tooth)
Cross-sections of a permanent tooth (wisdom tooth) were prepared by BIB (Broad Ion Beam) milling and observed using a Variable Pressure SEM. The two elongated holes in the whole image are root canals containing blood vessels and nerves. The tooth root surface is covered with a cementum layer showing a banded structure like trees thickening with age to form an annual-ring structure. This property has been used to determine the age of mammals. The cross-sectional image of the tooth neck shows the boundary between dentin and enamel. Though distinction between these two has been difficult with a torn surface, ion milled surface allows the identification. Four holes in the enlarged image are cross-sections of dentinal tubules regarded as to transmit pain and temperature.
