Bio-inspired, compact and low-energy mass exchanger for carbon dioxide capture

Device composed of microchannels lined with sorbent-infused textured surfaces for CO2 capture and release via electrochemical regeneration
Institute Reference:
Background
There is growing consensus among the global scientific community that significant CO2 removal (up to 10 Gigatonnes/yr) will be needed to limit the Earth’s temperature rise to less than 1.5 ºC. Current estimates for the cost to capture a tonne of CO2 from the air vary widely, ranging from $100 to $1,000 per tonne. Capture of CO2 emissions of 10 gigatonnes per year would require about 10,000 large-scale Direct Air Capture plants. With each plant costing up to $500m, this would entail an investment of about $5 trillion. In addition, each facility would need to be stocked with solvent to absorb 10 gigatonnes of CO2 and be regenerated. Clearly, a new technology paradigm is needed to enable cost‑efficient carbon capture.
Technology Overview
This CO2 capture approach is inspired by the pitcher plant which has a low-friction surface from a lubricant film trapped within the textures on the plant’s surface. Our design utilizes air (or flue gas) flow through micro/mini channels which are lined with sorbent-infused textured surfaces (SITS) that can capture CO2 from the flow stream.
Benefits
The enormous interfacial (gas-sorbent) area and mass transfer coefficient (per small hydraulic diameter) provided by micro or mini channels facilitates CO2 absorption. Importantly, the same device can be used for sorbent regeneration (electrochemical or thermal), wherein pure CO2 is released (for sequestration). Sorbent regeneration occurs in a periodic manner in the same device, wherein pure CO2 is released for sequestration. Electrochemical and/or thermal regeneration can be used. An additional benefit of the SITS is that they lubricate the streamwise flow of gas (per the menisci formed) relative to a no-slip (smooth) channel.
Applications
The mass exchanger concept has other applications including i) production of industrial gases, ii) alternative to existing processes involving gas-liquid mass exchange, iii) SOx, NOx, capture, iv) onsite O2 capture from air (a critical medical need) iv) high-performance heat exchangers and heat pipes.
Opportunity
We are interested in investment/ funding from interested parties to support both theoretical and experimental work to realize the technology. Work envisaged is (1) a detailed hybrid analytical-numerical approach to the study of CO2 (or other gas) mass transport along menisci of immobilized sorbents in textured surfaces, in order to predict the CO2 (or other gas) uptake rate, and (2) a holistic experimental approach to develop novel sorbents, which meet a multifunctional suite of properties related to CO2 selectivity, CO2 (or other gas) uptake capacity, gas diffusion, wettability, electrical conductivity and vapor pressure.

Throughput Enabled Rate Adaptation Methods

UCSC’s use of throughput as the single parameter for rate adaptation in TERA has led to a solution that is surprisingly simple, robust, and efficient. The design of TERA is based on the insight that providing effective rate adaptation in a wireless network is related to the throughput experienced by nodes at different data rates. Furthermore, end-user applications care about the throughput attained, rather than the transmission rate used or the loss ratios. TERA’s main method involves the wireless node: measuring the wireless node throughput attained while communicating at different data rates on a channel in the digital wireless communication network, calculating the measured throughput a current transmission rate (without any a priori knowledge of a state of the channel), and transmitting at the calculated rate. TERA determines a ratio of the measured throughput with respect to an exponential weighted moving average of the measured throughput, performed at a polling frequency, and decreased if the measured throughput oscillates. Extensive simulations and real-world experiments have shown that TERA consistently outperforms all prior rate adaptation schemes used to date (2014). less

Training Swimwear Garment to Address Injury Risk Factors

Such … moreSwimming-related injuries, including shoulder injuries, are common, with most injuries occurring during training sessions. Such injuries happen for various reasons, including lengthy training sessions, improper stroke movement/patterns, poor posture, and swimmer fatigue. Swimwear manufacturers have focused on addressing these issues by developing technical/high-tech swimsuits for short-duration competitive swimming rather than for extended use during training sessions. In addition to using high-tech swimsuits during competition, other injury prevention/recovery techniques include modifying training routines by resting/decreasing session length, using Kinesio taping of the shoulders, physical therapy, and wearing posture shirts. These methods can increase the amount of training required to maintain peak performance and may only address one cause of an injury (e.g., Kinesio tapes only address shoulder posture, not overall swimmer posture). Researchers at UC Davis have developed a swimwear garment that can be worn over traditional swimwear or against the skin. The swimwear garment helps to improve form and positioning in the water to reduce injuries and allows injured swimmers to continue training while recovering from their injury. The swimwear garment is focused on addressing injury risk factors by promoting core muscle activation, raising a swimmers body position in the water, improving shoulder posture to help reduce the possibility of injury. and assisting swimmers with posture and maintaining correct form. less

MAGNETIC RESONANCE ELASTOGRAPHY SYSTEM FOR THE PROSTATE

MRE has been used to image the prostate using a both abdominal and transperineal drivers to apply rapidly varying pressure to the perineum in order to produce the necessary compression waves. The transperineal driver provides a cylinder attached to a patient table with an internal movable piston driven pneumatically by a remote pressure source operating at about 45 Hz. Resulting MRE images produced using this driver suffer from poor quality due in part to patient motion.\r\n\r\nUW-Madison researchers have developed a lightweight, disposable, trans-perineal passive diver for magnetic resonance elastography. The device includes an anchoring mechanism that allows the passive driver to be secured firmly in place. The transperineal approach brings the passive driver much closer to the prostate and removes the intervening structures that interfere with wave propagation from the abdominal/pelvic wall approach. Active driver frequency can be increased (from ~60Hz to 100-110Hz) which significantly improves image resolution. The anchoring mechanism firmly fixes the passive driver to the perineum thereby mitigating patient-related motion. This approach improves image quality and reproducibility (which is a critical need for image-based biomarkers). less

Background:
Phase change memory (PCM) is a type of non-volatile RAM that stores data by changing the state of the material used, back and forth between amorphous and crystalline states. PCM has emerged in recent years by offering great potential for future non-volatile solid-state memory. Multilevel storage (storage of multiple bits in a memory cell) and storage of analog data comprise a key factor for the competitiveness of PCM technology in the nonvolatile memory market. Multilevel storage techniques can increase storage density and reduce energy consumption in PCM devices. Analog processing and storage are considered disruptive emerging technology for neuromorphic computer applications. However, accurately controlling the phase transitions as well as understanding the underlying switching mechanisms are still hindering the wider adoption of PCM multi-level memory technology.
Technology Overview:
This technology is a novel group III-Antimonide phase change memory (PCM) materials that comprise likely candidates for multilevel and analog PCM devices. The technology uses thin films of group Ill-Sb alloys (AISb, GaSb and AIGaSb) deposited on TiN or W plugs in a Si/SiO2 structures to form mushroom-type PCM cells. The technology provides improved scalability, reduced complexity and cost, multilevel data read/write with high data retention, and endurance. These features will enable the fabrication of PCM devices that meet the requirements for distributed self-learning hardware (such as smart sensors) and neuromorphic fabrics for artificial intelligence and big data analysis.

An important method … more Renewable hydrogen is necessary to enable a transition to clean fossil-fuel free energy. An important method of producing clean hydrogen is electrolysis of water and one key component of such electrolyzers is the PEM.In order to commercially deploy electrolyzers it is necessary to design the appropriate configuration of the PEM.However, PEMs are difficult to model because complex fluid dynamics and chemical reactions depend on porosity, thickness, pore size, and other factors.This software allows for the accurate modeling of the porous transport layer and the channel-land structure of PEMs and thus allows manufacturers to design high-performance electrolyzers. less

The design repurposes the existing hardware mechanisms for translating memory addresses to also provide translation for internal storage addresses, namely the IOMMU.
While other technologies exist to allow direct device access, this innovation does not allow access to files (only raw devices) and does not support shared access from multiple applications. First, a kernel maps a file into user space at a “File Virtual Address” (FVA) and creates augmented page table entries for this address. Then the user process accesses the device directly using instructions along with FVA and a process address space ID. The device employs IOMMU to translate FVA to Logical Block Addresses (LBA); translation fails if user doesn't have access permissions. less
