The innovation described here consists of synthesizing in a one-step process a self-standing electrode with single-atom catalysts (SACs) supported on a nanocarbon matrix that will outperform the established standards at a much cheaper cost for most electrocatalytic reactions. The scientific breakthrough supporting this research is based on the simultaneous delamination and doping of a thin film stack using chemical vapor deposition (CVD).

The Vcc level and temperature of IC’s are important parameters which determine the power / performance. Resonances in the package and platform can cause significant AC voltage droops which can degrade functionality, requiring additional guard-band. Prior-art droop detectors utilize digital delay circuits, such as tunable replica circuits to measure these droops. However, the delay is a strong function of temperature as well as the DC Vcc level, making it difficult to differentiate the AC droop across different voltage and temperature levels. It is proposed to utilize a current controlled oscillator (CCO) with an analog bias to mitigate the voltage and temperature dependencies, such that only the AC droop is measured. The CCO frequency is independent of the DC Vcc level, while the temperature is also characterized along with the AC droop, such that both temperature and droop levels can be extracted. The sensor can measure droops and temperature to an accuracy of 10mV and ±3oC respectively. The circuit occupies 8800 μm2 in 65nm with a power consumption of 297 µW. This circuit is very useful to characterize the power grid in design for test (DFT) applications as well as on-the-fly real time chip operation.

A Droop mitigation system is featured which includes an inverter-based droop detector as well as Dual Mode Logic (DML). The droop detector is based on capacitor ratios and is thus insensitive to PVT. The DML logic can alter its power/performance ratio based on the droop level input it receives from the detector, such that the critical timings are preserved. The droop detector consumes 62uW, has a response time of 2ns and an accuracy of 0.9%, making it one of the fastest, most accurate, and lowest power droop detectors in its class. A ripple carry adder is demonstrated, with DML logic in its critical path, which can maintain timing for droops as high as 400mV.

An electrochemical reactor that works in asymmetric method using flow electrodes to produce low cost green hydrogen gas. The electrochemical cell produces hydrogen using faradaic reaction for hydrogen evolution and capacitance electrostatic adsorption instead of oxygen evolution. Based on our Nofar scholar research, we developed and improved the device that is based on the described patent named:"METHOD AND APPARATUS FOR HYDROGEN PRODUCTION BY ELECTROLYSIS". Instead of using a static electrodes for the capacitance behavior we use flow electrodes that allows the regeneration of the electrodes outside the reactor in a different cell; hence, we do not require to pause the evolution of hydrogen for electrode regeneration and we need less electrodes that lower the cost of the electrochemical reactor.

All-solid-state sodium batteries offer a promising route toward safe, low-cost, and sustainable energy storage, but their widespread adoption is limited by the lack of solid electrolytes that simultaneously provide high room-temperature ionic conductivity, mechanical flexibility, thin-film processability, and long-term electrochemical stability. Here we introduce a composite solid-state electrolyte based on surfactant-modified sodium-enriched halloysite nanotubes dispersed in polymeric medium. Sodium exchange and surface functionalization transform the naturally abundant clay into an active ion-conducting filler that forms continuous Na⁺ transport pathways while remaining compatible with scalable polymer processing. The resulting self-supporting membranes are as thin as 10 μm, contain up to 50 wt% halloysite while retaining mechanical flexibility, and exhibit a room-temperature ionic conductivity of 3.13 mS cm⁻¹ together with an electrochemical stability window of 4.7 V versus Na/Na⁺. Symmetric Na|Na cells sustain stable cumulative stripping/plating of 500 mAh cm⁻², while Na₃V₂(PO₄)₃|Na cells deliver stable cycling over 5,000 cycles at 20 C with high capacity retention. These results establish naturally abundant halloysite nanotubes as an effective platform for high-performance solid-state sodium electrolytes and demonstrate a scalable strategy for combining fast ion transport, mechanical robustness, and practical battery performance.

Brought herein a novel system for periodic capture and release of CO2 from air using asymmetric configuration electrochemical cells. The capture and release mechanism are based on the "pH swing" principle in which CO2 is efficiently being absorbed into alkaline solution and being released when the solution becomes acidic. Adjustment of the pH of the solution is controlled by passing current through a special asymmetric electrochemical reactor where the solution passes through the reactor. Absorption of CO2 from the air or exhaust gas ("flue gas") is facilitated by passing the solution and CO2 through ordinary absorption column (or tower).

The demand for computational performance continues to rise exponentially, while power and thermal budgets impose strict limitations on integrated circuits (ICs). Modern processors employ multiple power domains, each requiring accurate current sensing for efficient power management. Existing current sensing techniques—such as shunt, Hall-effect, and fluxgate sensors—are either too large, too power-hungry, or too slow for integration at the scale of tens or hundreds of domains within a single chip. Digital ring-oscillator (RO) sensors have been explored, but they exhibit strong non-linearity, temperature, and supply dependence, which severely limit their accuracy. This research proposes a fundamentally new approach: a differential current-controlled oscillator (CCO) amplifier, which directly converts differential current or voltage into a frequency domain signal. Unlike conventional amplifiers, the CCO itself acts as both amplifier and analog-to-frequency converter, providing a highly compact, low-power, and fast solution suitable for power-gate current sensing in advanced processors. The proposed sensor targets an accuracy better than 0.2%, conversion time below 2 μs, power consumption under 20 μW, and area smaller than 0.01 mm², yet with performance significantly surpassing existing state of-the-art designs. Novel circuit techniques are introduced for non-linearity correction, temperature compensation, and common-mode rejection, including bias trimming, replica oscillators, and chopper stabilization. Preliminary simulations of a 65nm implementation demonstrate excellent linearity, 60 dB dynamic range, and temperature- and supply-induced variation below 0.02% when using replica compensation. This project will establish a new class of analog amplifiers based on differential CCOs, enabling fine-grained, energy-efficient current sensing for multi-domain processors, GPUs, and AI accelerators. The outcomes are expected to impact both industrial and academic fields by providing a compact, low-cost, low power sensing solution for power-management architectures and extending its use to applications such as biomedical monitoring, smart-grid systems, and energy-harvesting circuits.
