Recent progress in the fabrication of nanostructures has led to their application in numerous fields, including materials engineering, environmental remediation, biomedicine, and more. In particular, nanostructure nanochannels with at least one physical dimension smaller than 100 nm are actively studied for their potential use in DNA stretching, nanofluidics, and artificial membranes.

For example, in traditional DNA testing methods based on polymerase chain reaction, a single mutated gene is easily treated as noise. Inside nanochannels with sub-100-nm diameter, the DNA molecule can be stretched along a line. As a result, it is possible to investigate the base pairs one-by-one along a single DNA, through which the single mutated gene...

A smartphone-based system that relies on OCT to detect jaundice in newborns will be put to use diagnosing very young patients in the U.S. and Nigeria, thanks to a nearly $500,000 grant from the National Institutes of Health (NIH). The NIH awarded the grant to the lab of Audrey Bowden, an associate professor in the Department of Biomedical Engineering at Vanderbilt University, to test the usability of the system prototype, in the vicinity of Vanderbilt and in a clinical setting in Nigeria.

The basic concept of the device was presented by lab members earlier this year at SPIE Photonics West. The device is essentially a visible light OCT system with a single-mode fiber illumination source, using the camera of a commercial smartphone and...

Frigate Sachsen successfully engaged UAVs at short ranges in Baltic near Putlos military training area.

Digital lidar company Ouster and lidar sensors and solutions developer Velodyne Lidar have entered into a definitive agreement to merge in an all-stock transaction. The combination reportedly brings together roughly $400 million in market value.

Under the terms of the agreement, which the companies signed Friday, Nov. 4, each Velodyne share will be exchanged for 0.8204 shares of Ouster at closing. The transaction will result in existing Velodyne and Ouster shareholders each owning approximately 50% of the combined company, based on current shares outstanding.

Both companies will continue to operate their businesses independently until the close of the merger transactions. The merger transactions are expected to be completed in...

U.S. national laboratories will see an infusion of cash from the Inflation Reduction Act, amounting to $1.5 billion to fund facility upgrades, modernized infrastructure, and deferred maintenance projects.

According to U.S. Secretary of Energy Jennifer Granholm, the funding represents one of the largest ever investments in national laboratory infrastructure. Specifically, the funding includes $294 million for "Basic Energy Sciences" and $303 million for "High Energy Physics," both of which contain multiple laser- and synchrotron-related projects. Among the projects receiving funding are the Linac Coherent Light Source-II High Energy at SLAC National Accelerator Laboratory, receiving $96 million; the Advanced Light Source Upgrade at...

In laser powder bed fusion (LPBF) for the additive manufacture of metal parts, local high-temperature molten metal fits the surrounding solid part as a result of thermal expansion. As a negative byproduct of this process, the molten metal generates a negative thermal stress following solidification, which produces an in-plane residual stress.

This residual stress accumulates toward the upper layer with the repetitive formation process on each layer and often leads to undesirable effects such as delamination, cracking, and warpage.

Moreover, residual warpage and deformation are asymmetric in nature and scale with the size of the fabricated metal part. As a result, the integrated molding of large metal parts, such as rocket...
