SACLA Magnifies World's Smallest Object – X-ray Free Electron Laser
SACLA, pronounced (Sa-Ku-Ra), is the free-electron laser, or X-FEL in Japan, embedded in the SPring-8 accelerator and synchrotron complex. Operational since 2011, it is the brightest X-ray source of the world.

This video introduces the 700 meter long X-ray laser facility SACLA, where things that are a billionth of a millimeter become visible. This feat is made possible with a powerful X-ray laser. The electrons are drastically accelerated until a light that is a hundred million times a hundred million times brighter than sunlight is produced. This makes it possible for scientists to observe things that were once limited to speculation. A collection of Japan's original and sophisticated technologies was used to create SACLA, a giant microscope that can reveal objects on the atomic level. Watch video >

The 2016 Nobel Prize in Physiology or Medicine
Akihito Yamano and Joseph D. Ferrara, Rigaku Corporation and Rigaku Americas Corporation

The Nobel Prize in Physiology or Medicine was awarded to a Japanese scientist for the second year in a row for 2016. The laureate is Professor Yoshinori Osumi of the Tokyo Institute of Technology who received the award for the discovery of autophagy. Generally speaking, knowledge of autophagy is limited to researchers in biology related fields, therefore the achievement of Professor Osumi may not be understood immediately as compared to the work by Professor Satoshi Omura discovering ivermectin which prevents blindness in over 300,000 people every year.

Report on AXAA 2017
Reported by Dr. Cameron Chai, Marketing Communications Manager, AXT

The Australian X-Ray Analytical Association Workshop, Conference and Exhibition is the premiere event for the analytical X-ray community in the region. It is held every two years and hence it is imperative that we are well represented at this event. AXT, in conjunction with Rigaku and Rigaku Oxford Diffraction, took out a gold sponsorship package and were well represented throughout the entire event, which also served as the launching pad for "The Unfair Advantage" marketing program.

X-Ray Diffraction Analysis of Abrasives in Household Cleaning Products
AXT Pty Ltd (AXT)

Household cleaning products come in different forms, from aerosols to gels and creams through to pastes. They may contain a plethora of chemicals designed to tackle various tasks from disinfecting to removing stains and grease, as well as chemicals such as surfactants, polishes and detergents. In this study we examined three common household cleaning products using X-ray diffraction to determine what crystalline materials (if any) were present. For more >

Sulfur Analysis in Petroleum Products by WDXRF According to ASTM D2622-10
Rigaku Corporation

Crude oil contains sulfur in concentration from 0.5 mass% to 5.0 mass% typically, and control of the level of sulfur in refinery intermediates and final products is critical in a refinery. Sulfur in petroleum-based fuels contributes to atmospheric pollution; therefore, sulfur content in fuels, especially in automobile fuels, is strictly controlled. Sulfur also causes damage to facilities such as catalysts in refinery processes. Therefore, control of sulfur content is very important in the petroleum industry from the standpoints of both environment and production cost.

Algorithms to Live By: The Computer Science of Human Decisions: Brian Christian and Tom Griffiths

I came across this title in the list of books Amazon thought I might like. It sat in my "to read" pile for a couple of months until I finally read it over the holidays. It is the most fun self-help book I have read in quite a while. The authors, Brian Christian and Tom Griffiths, are both experts in cognitive science. Christian has published articles in The Wall Street Journal, The Atlantic, Gizmodo, and Cognitive Science, to name a few places. Griffiths is the director of the Computational Cognitive Science Lab at UC Berkeley. Read full review >

News for February 2017

February 2, 2017. Takayuki Iwasaki, Mutsuko Hatano and colleagues at the Tokyo Institute of Technology, the Japan Science and Technology Agency (JST) and Toshiharu Makino at the National Institute of Advanced Industrial Science and Technology (AIST) report a new method for sensing electric fields at the interior of operating semiconductor devices. The technique exploits the response of an artificially introduced single electron spin to variations in its surrounding electric field.

February 2, 2017. US scientists who analysed the energy spectrum of X-rays gathered by NASA's Chandra satellite claim that a small but distinctive signal in X-rays from the Milky Way could be key to proving the existence of dark matter.

February 6, 2017. A giant black hole ripped apart a nearby star and then continued to feed off its remains for close to a decade, according to research. This black hole meal is more than 10 times longer than any other previous episode of a star's death.

February 7, 2017. An international team led by researchers at Nagoya University has identified a new type of solar event and dated it to the year 5480 BC; they did this by measuring carbon-14 levels in tree rings, which reflect the effects of cosmic radiation on the atmosphere at the time. They have also proposed causes of this event, thereby extending knowledge of how the sun behaves.

February 7, 2017. NASA scientist William Zhang has created and proven a technique for manufacturing lightweight, high-resolution X-ray mirrors using silicon – a material commonly associated with computer chips. Data shows that single-crystal silicon works exceptionally well as an X-ray optic.

February 8, 2017. Layered ruthenate Ca2RuO4-y ceramic shrinks by a record-breaking 6.7% when heated. Japanese researchers based at Nagoya University discovered this ceramic material that contracts on heating by more than twice the previous record-holding material.

February 10, 2017. Scientists have invented a new kind of thin material that can cool a surface against the heat of the sun without using energy or typical air conditioning. The glass-polymer hybrid material measures just 50 μm thick—slightly more than aluminum foil—and can be manufactured cheaply.

February 14, 2017. Following a false alarm in 2004, two groups report what could be the first observation of supersolids, a theoretically predicted state of matter that is both a superfluid and a solid at the same time.

February 20, 2017. Drops of a water—alcohol mixture exploding into millions of tiny droplets have been observed by Etienne Reyssat and colleagues at the Institute of Industrial Physics and Chemistry in Paris. The explosions occur when the liquid is placed on a layer of oil. The physicists say that the process is driven by a combination of evaporation, surface tension and fluid flow.

February 21, 2017. Researchers at Berkeley Lab for NASA Ames Research Center are exploring next-generation spacecraft materials at the microscale using an X-ray technique that produces 3-D images. This work could help ensure future spacecraft survive the rigors of otherworldly atmospheres.

February 21, 2017. International scientific collaboration more than doubled worldwide between 1990 and 2015, according to new research led by Caroline Wagner, an Ohio State University science and technology policy professor. Her work revealed that the number of multiple author scientific papers with collaborators from more than one country rocketed from 10% to 25% during those 15 years.

February 22, 2017. Scientists at the Earth-Life Science Institute at the Tokyo Institute of Technology report unexpected discoveries about the Earth's core. The findings include insights into the source of energy driving the Earth's magnetic field, factors governing the cooling of the core and its chemical composition, and conditions that existed during the formation of the Earth.
