Read More Dr. Yurii Vlasov from the University of Illinois has developed a single-chip neural nanodialysis probe that can sample in vivo brain chemicals, store them, and then directly deploy them for analysis, all while maintaining high temporal resolution. This device uses reversible inlets-outlets and embedded ionization ports to both sample in vivo brain chemicals and deploy them, without need for intermediate storage. This risks less contamination or Taylor dispersion than other methods, and reduces the need for bulky peripherals. Application This can be used for collecting and analyzing in-vivo biochemical concentrations in the brain. Benefits This is a single chip silicon neural probe that can sample live chemicals, store them, and then directly deploy them for analysis. Other neural probes cannot store and deploy these chemical samples, which reduces the temporal resolution of the samples.

These phase-separated optical fibers have high loss (0.05 to 5 dB/m @ 1550 nm) when compared with conventional optical fibers, and the loss dominated by Rayleigh scattering. Moreover, these phase separated fibers are produced through a molten core method (MCM) which makes the cost of production relatively low when compared with conventional fibers. When employed in a Rayleigh based distributed sensor these phase-separated optical fibers provide short-range sensitivity that is orders of magnitude greater than conventional fibers.

By injecting and trapping charges within a thin dielectric layer, a Coulomb barrier is created that prevents leakage currents that cause capacitors to discharge more quickly. Initial applications for the technology are in cold electronics, which could include quantum computing, space technologies, infrared cameras, or MRI machines.

Read More This method of forming a nanoscale three-dimensional pattern in a porous semiconductor includes providing a film comprising a semiconductor material and defining a nanoscale metal pattern on the film, where the metal pattern has at least one lateral dimension of about 100 nm or less in size. Semiconductor material is removed from below the nanoscale metal pattern to create trenches in the film having a depth-to-width aspect ratio of at least about 10:1, while pores are formed in remaining portions of the film adjacent to the trenches. The method can be extended to form self-integrated porous low-k dielectric insulators with copper interconnects.

The invention allows for the fabrication of high-quality-factor milliTesla- and Tesla-level inductors for high density circuit applications and allows for the precise tuning of the inductor performance by varying the space between subsequent turns (coils), which affects the thickness of the conducting layers within the inductor. Importantly, this method provides tunable three-dimensional inductors with a reduced footprint when compared with conventional planar inductors.

Read More Standard red LEDs suffer from rapid degradation and low efficiency, which becomes increasingly poor at smaller dimensions. Dr. Lee’s novel LED design integrates InP quantum dots to overcome the deleterious sidewall recombination that reduces the performance of conventional red LEDs. This technology dramatically increases the defect tolerance of red LEDs, with devices showing comparable performance when grown on a range of surfaces including GaAs and GaAs/Si.

The novel method of a liquid environment enables the improvement of these materials without involving a normally difficult manufacturing process. The process enables the control of oxygen vacancies to a certain depth and density. The removal of the defect allows for the metal oxide thin-film to have better photocatalytic properties. This could be useful for sensors and power devices which are a quickly growing market. The filled vacancies also affect subsequent redox reactions by inhibiting the transfer of electrons.
