China’s big win.

Last week a team from Chinese 3D printing construction company WinSun visited Saudi Arabia, meeting with department of housing official and others to discuss the kingdom’s housing shortfall.

According to 3ders.com and others, the Chinese firm’s chairman and vice president met officials from the housing department and investment authority, and were told the Saudi government believes WinSun’s technology could help meet a shortage in available housing. WinSun was invited to open a Saudi factory.

According to an April report from Reuters, the Arab state is looking at a shortfall of 1.5 million housing units over the next five years.

Nice.

Summary: “Nano satellite missions are low-cost and can do multiple jobs with a greater degree of accuracy. “It will be an advanced nano satellite weighing about one kg designed for a specific task of conducting oceanographic studies. S Satheesh Chandra Shenoi, Director, Indian National Centre for Ocean Information Services (INCOIS) and National Institute of Ocean Technology, said it’s good that educational institutions are venturing into space programmes. Close on the heels of the successful launch of SATHYABAMASAT, which the students of Sathyabama University worked on since 2009 to monitor the greenhouse gas concentration in the atmosphere, the Academy of Maritime Education and Training (AMET) is working on an ocean observation “AMETSAT — Nano Satellite Project” with the national space agency. Also, the incidences of aircrafts such as the Indian Air Force AN-32 going missing leaving no clues warrant more ocean observation satellites, though with little larger life span, unlike nano satellites which usually have a life space of 6 months, another AMET faculty member said.

CHENNAI: With the Indian Space Research Organisation (ISRO) opening its arms to educational institutions and private industry to participate in space exploration missions, there is a renewed enthusiasm among researchers and student community. Close on the heels of the successful launch of SATHYABAMASAT, which the students of Sathyabama University worked on since 2009 to monitor the greenhouse gas concentration in the atmosphere, the Academy of Maritime Education and Training (AMET) is working on an ocean observation “AMETSAT — Nano Satellite Project” with the national space agency. G Thiruvasagam, Vice-Chancellor, AMET, made the announcement during the sixth convocation held here on Wednesday. The deemed university has also bagged a project on “Marine Exploration of Submerged Poompuhar and Dwarka”. N Manoharan, Director, Research of AMET, told Express on the sidelines of the convocation that the project was in an early stage.

All material things appear to be made of elementary particles that are held together by fundamental forces. But what are their exact properties? How do they affect how our universe looks and changes? And are there particles and forces that we don’t know of yet?

Questions with cosmic implications like these drive many of the scientific efforts at the Department of Energy’s SLAC National Accelerator Laboratory. Three distinguished particle physicists have joined the lab over the past months to pursue research on two particularly mysterious forms of matter: neutrinos and .

Neutrinos, which are abundantly produced in nuclear reactions, are among the most common types of particles in the universe. Although they were discovered 60 years ago, their basic properties puzzle scientists to this date.

Nice and Kudos to ORNL.

A team led by Jonathan Poplawsky of the Center for Nanophase Materials Sciences used advanced microscopy techniques to discover efficiency differences of crystalline structures of various mixtures of cadmium, tellurium and selenium. In fact, selenium is an integral part of the formulation that resulted in a world record for solar cell efficiency. The team’s paper is published in Nature Communications.

While some of today’s solar cells use a blend of cadmium and tellurium to convert light into electricity, adding the optimum amount of selenium in the right places could help increase efficiency from the current mark of about 22 percent to levels approaching the theoretical limit of 30–33 percent. The trick is to determine the best ratio of selenium.

“Using different microscopy methods, we were able to gain a better understanding of the phases, compositions and crystalline structures that allow these materials to convert light into electricity more efficiently,” said Poplawsky, adding that the availability of data is limited. “In some instances, adding too much selenium changes the crystalline structure of cadmium-tellurium and dramatically reduces the conversion efficiency.”
