Atomically thin materials such as graphene have drawn attention for how electrons can race in them at exceptionally quick speeds, leading to visions of advanced new electronics. Now scientists find that similar behavior can exist within two-dimensional sheets, known as domain walls, that are embedded within unusual crystalline materials. Moreover, unlike other atomically thin sheets, domain walls can easily be created, moved, and destroyed, which may lead the way for novel circuits that can instantly transform or be repaired on command.

In the new study, researchers investigated crystalline lithium niobate ferroelectric film just 500 nanometers thick. Electric charges within materials separate into positive and negative poles, and ferroelectrics are materials in which these electric dipoles are generally oriented in the same direction. The electric dipoles in ferroelectrics are clustered in regions known as domains. These are separated by two-dimensional layers known as domain walls.

The amazing electronic properties of two-dimensional materials such as graphene and molybdenum disulfide have led researchers to hope they may allow Moore’s Law to continue once it becomes impossible to make further progress using silicon. Researchers have also investigated similarly attractive behavior in exceptionally thin electrically conducting heterointerfaces between two different insulating materials, such as lanthanum aluminate and strontium titanate.

Singer is the founder and director of Outreach Judaism, a Jewish counter-missionary organization. It describes itself as “an international organization that responds directly to the issues raised by missionaries and cults, by exploring Judaism in contradistinction to fundamentalist Christianity.” Singer cautions regarding congregations that “are designed to appear Jewish, but are actually fundamentalist Christian churches, which use traditional Jewish symbols to lure the most vulnerable of our Jewish people into their ranks.” Outreach Judaism was described by J. Gordon Melton in 2002 as an example of “the current state of Jewish counter-cult activity.”

Rabbi Tovia Singer wanted to understand why Jews have been persecuted throughout history so he read the New Testament and found out why they have been targeted. It appears Rabbi Tovia Singer has devoted his life to showing how the authors of the New Testament corrupted the Hebrew scriptures in the Septuagint. He shows how Paul manipulated the text just as bad as modern tv preachers to suite his gentile audience.

South Korea’s Samsung Electronics has launched a new and its largest chip production line. The new factory was opened in Pyeongtaek, South Korea, 70 km from Seoul.

Here’s what we know

Despite the September 7 launch, the P3 line began operating as early as mid-summer. Samsung started trial production of NAND memory in July. The new facility uses ASML’s lithography machines. It is the dutch company, which is essentially a monopolist in the extreme ultraviolet lithography equipment market.

Researchers have developed a camera that uses a thin microlens array and new image processing algorithms to capture 3D information about objects in a scene with a single exposure. The camera could be useful for a variety of applications such as industrial part inspection, gesture recognition and collecting data for 3D display systems.

“We consider our camera lensless because it replaces the bulk lenses used in conventional cameras with a thin, lightweight microlens array made of flexible polymer,” said research team leader Weijian Yang from the University of California, Davis. “Because each microlens can observe objects from different viewing angles, it can accomplish complex imaging tasks such as acquiring 3D information from objects partially obscured by objects closer to the camera.”

In the journal Optics Express, Yang and first author Feng Tian, a doctoral student in Yang’s lab, describe the new 3D camera. Because the camera learns from existing data how to digitally reconstruct a 3D scene, it can produce 3D images in real time.

You can get down off the table – they’re not in the wild yet. But it’s reasonable to ask why they’d do such a thing.

It’s not because they have a nasty streak. Animals fitted with electronic devices can get into places that humans can’t go.
