Read More Dr. Diao from the University of Illinois at Urbana-Champaign has developed a method for generating highly-aligned thin films using existing large-area coating techniques. Utilizing a novel dynamic templating technique thin films are generated with highly-aligned polymer crystals. The resulting thin films have improved charge transport and directionality compared to conventionally generated thin films. This method is applicable to a wide-array of molecular systems unlike current templating methods which are highly specific and narrow in their applicability.

Read More Dr. Seok Kim from the University of Illinois at Urbana-Champaign has developed a versatile surface material that will serve as a general-purpose platform for fluid and light manipulations for micro and macroscale. Potential applications include: digital microfluidics, biomedical devices, virtual blinds, camouflage surfaces, and micromirror arrays. Compared to similar surfaces, this responsive surface consists of micropillars integrated with large area platelets, which increases the areal fraction of opaque regions on the surface and increases the tuning range of transmittance. It does not require heating to create a vapor layer, and allows the use of soft, ferromagnetic micropillars and offers a more efficient assembly process than prior works. Lastly, it allowed control over the final configuration of the platelets, either in-plane or out-of-plane configurations, for the very first time.

The fabrication technique uses porous silicon as a scaffold for photoresist in a direct laser write process to make graded index (GRIN) optics and photonic elements. This technology has the potential to dramatically improve the speed, density, and energy efficiency in applications like telecommunications, computing, data storage and transfer and consumer electronics.

This invention assists with the management of thermal energy (quantum defect heating) which can lead to failure of an optical fiber when power scaling fiber-based lasers. A Yb-doped multicomponent flurosilicate optical fiber reduces quantum defect heating in the fiber-based laser. Fiber-based lasers have applications in the automotive, medical, and electronics industries.
Frequency Independent Framework for Synthesis of Programmable Non-reciprocal Network Dr. Songbin Gong and his group from the University of Illinois have developed a framework for synthesizing frequency-independent multi-port nonreciprocal networks. The... Read More Dr. Songbin Gong and his group from the University of Illinois have developed a framework for synthesizing frequency-independent multi-port nonreciprocal networks. The framework is highly expandable, can have an arbitrary number of ports while simultaneously sustaining balanced performance, and provide unprecedented programmability of non-reciprocity. Unlike the conventional approaches, non-reciprocal performance of the network is only dependent of the time delays, instead of phase delays, and therefore is frequency independent. This technology could inspire new ways of implementing multiple input multiple output (MIMO) communication systems. 4-port switch module prototype

Read More This technology is a classifier based on a ferroelectric graphene transistor. In contrast to traditional current-mode classifiers based on CMOS technologies (which require 23 transistors per pixel), this classifier requires only one transistor per pixel. The device provides a new solution for image recognition with reduced circuit complexity, enhanced energy efficiency, and faster processing speed. Applications include signal or image processing and recognition.

Read More Dr. Kim from the University of IL has developed a special driver that creates an illusion of the existence of an Ethernet interface between the host- and SSD-side processors which does not require any changes in the OS network creating a virtual Ethernet interface for each SSD connected to the host-side processor over PCI interfaces. The proposed architecture taps into SSD computing capabilities mitigating system I/O bus bottlenecks. This application can be used for data intensive applications across industries.
