ScatterMIMO: Enabling Virtual MIMO with Smart Surfaces. ScatterMIMO is a programmable smart surface that contains phase shifters to change the wireless channel

In the last decade, the bandwidth expansion and MIMO spatial multiplexing have promised to increase data throughput by orders of magnitude. However, we are yet to enjoy such improvement in real-world environments, as they lack rich scattering and preclude effective MIMO spatial multiplexing.

Bioactive Plastics With Programmable Degradation And Microplastic Elimination

Although the plastic waste crisis has reached a breaking point, current recycling approaches are unable to remediate microplastic pollution. Biodegradable and renewable plastics have shown promise but impact neither microplastic elimination nor complete plastic recycling due to diffusion-limited enzymatic surface erosion and random chain scission. Here it is shown that nanoscopic dispersion of trace enzyme (e.g. lipase) in plastics (e.g. polycaprolactone [PCL]) leads to fully functional plastics with eco-friendly microplastic elimination and programmable degradation. Nanoscopic enzyme encapsulation leads to:continuous degradation to achieve 95% microplastic eliminationa single chain-based degradation mechanism with repolymerizable small molecule by-products via selective chain end scission rather than random chain scissionspatially- and temporally-programmable degradation of melt-processed host matrix due to the dependence of single chain degradation on local lamellae thickness regardless of bulk percent crystallinity formulation of conductive ink for 3-D printing with full recovery of the precious metal filler With recent developments in synthetic biology and genome information, nanoscopically embedding catalytically active enzymes in plastics may lead to an immediate, environmentally friendly and technologically viable solution toward microplastic elimination and material recycling.

Reticulation Of Macromolecules Into Crystalline Networks

Covalent organic frameworks (COFs) are 2D or 3D extended periodic networks assembled from symmetric, shape persistent molecular 5 building blocks through strong, directional bonds. Traditional COF growth strategies heavily rely on reversible condensation reactions that guide the reticulation toward a desired thermodynamic equilibrium structure. The requirement for dynamic error correction, however, limits the choice of building blocks and thus the associated mechanical and electronic properties imbued within the periodic lattice of the COF.   UC Berkeley researchers have demonstrated the growth of crystalline 2D COFs from a polydisperse macromolecule derived from single-layer graphene, bottom-up synthesized quasi one-dimensional (1D) graphene nanoribbons (GNRs). X-ray scattering and transmission electron microscopy revealed that 2D sheets of GNR-COFs self-assembled at a liquid-l quid interface stack parallel to the layer boundary and exhibit an orthotropic crystal packing. Liquid-phase exfoliation of multilayer GNR-COF crystals gave access to large area bilayer and trilayer cGNR-COF films. The functional integration of extended 1D materials into crystalline COFs greatly expands the structural complexity and the scope of mechanical and physical materials properties.

Low Energy and Noise Sub-Sampling Phase-Locked Loop

Phase locked loops are widely employed in radio, telecommunications, computers and other electronic applications. They can be used to demodulate a signal, recover a signal from a noisy communication channel, generate a stable frequency at multiples of an input frequency, or distribute precisely timed clock pulses in digital logic circuits such as microprocessors. Researchers at the University of California, Davis have invented a novel, sub-sampling phase-locked, loop (SSPLL) that uses a sub-sampling lock detector (SSLD) to monitor the harmonic selected by the SSPLL. This technology requires lower energy consumption and reduces signal noise.

Fast Deep Neural Network (DNN) Training/Execution on Hardware Platforms

With the growing range of applications for Deep Neural Networks (DNNs), the demand for higher accuracy has directly impacted the depth of the state-of-the-art models.

The system allows patients to independently practice hand and arm movements, improving therapeutic outcomes, while reducing hospital visits and cost for both patients and healthcare providers.

Advanced Power Management IC’s for Li-Ion Powered Mobile & IoT Devices

Most modern mobile, wearable, and Internet of Things (IoT) devices utilize Li-ion batteries as power supplies. Since the 2.8-4.2V Li-ion output voltage range is not compatible with the 0.6-1.0V voltage requirements of most system-on-chips (SoCs) implemented in scaled CMOS, a DC-DC converter, typically implemented as a discrete power management integrated circuit (PMIC), is placed between the battery and the load.
