This artist's rendering shows a newly discovered planet (far right) orbiting one star (right) of a binary star system. The discovery, made by a collaboration of international research teams and led by researchers at The Ohio State University, expands astronomers' notions of where to look for planets in our galaxy. The research was funded in part by NASA.

Making dreams come true: Making graphene from plastic?

Graphene is gaining heated attention, dubbed a "wonder material" with great conductivity, flexibility and durability. However, graphene is hard to come by due to the fact that its manufacturing process is complicated and mass production not possible. Recently, a domestic research team developed a carbon material without artificial defects commonly found during the production process of graphene while maintaining its original characteristics. The newly developed material can be used as a substitute for graphene in solar cells and semiconductor chips. Further, the developed process is based on the continuous and mass-produced process of carbon fiber, making it much easier for full-scale commercialization.

How to manufacture transparent and conductive carbon nanosheet using PIM-1 polymer solution: (a) Quart substrate is being coated with PIM-1 polymer solution with ladder structure and conducts heating in high temperature to manufacture carbon nanosheet. Without any additional process OSC (organic solar cell) can be made directly on the sheet to manufacture solar cells. (b), (c), (d) show thickness, surface resistivity and transparency of the carbon nanosheet, respectively in relation to the concentration of PIM-1. Also, the new method easily controls the unwanted effects from the electronic and optical characteristics of carbon nanosheet, which is produced when the polymer solution is concentrated. As the high molecule solution concentration gets higher as shown in (Axis X, (b),(c)), the thicker it gets as shown in Figure (b) but, it becomes less resistant as shown in Figure (c), and the current flow better.

A Stellar Womb Shaped and Destroyed by its Ungrateful Offspring

The little-known cloud of cosmic gas and dust called Gum 15 is the birthplace and home of hot young stars. Beautiful and deadly, these stars mould the appearance of their mother nebula and, as they progress into adulthood, will eventually also be the death of her.

Black Hole Fireworks in Nearby Galaxy

pia18461-640_0.jpg
A galaxy about 23 million light-years away is the site of impressive, ongoing, fireworks. Rather than paper, powder, and fire, this galactic light show involves a giant black hole, shock waves, and vast reservoirs of gas.

Not Much Force: Berkeley Researchers Detect Smallest Force Ever Measured.

Stamper-Krun-Shreppler-300x194.jpg
Mechanical oscillators translate an applied force into measureable mechanical motion. The Standard Quantum Limit is imposed by the Heisenberg uncertainty principle, in which the measurement itself perturbs the motion of the oscillator, a phenomenon known as “quantum back-action.”
