Simple, scalable mechanosynthesis of metal-organic frameworks using liquid-assisted resonant acoustic mixing (LA-RAM).

ABSTRACT: We present a rapid and readily scalable methodology for the mechanosynthesis of diverse metal-organic frameworks (MOFs) in the absence of milling media typically required for other types of mechanochemical syntheses. We demonstrate the use of liquid-assisted resonant acoustic mixing (LA-RAM) methodology for the synthesis of three- and two-dimensional MOFs based on Zn(ii), Co(ii) and Cu(ii), including a mixed ligand system. Importantly, the LA-RAM approach also allowed the synthesis of the ZIF-L framework that has never been previously obtained in a mechanochemical environment, as well as its Co(ii) analogue. Straightforward scale-up from milligrams to at least 25 grams is demonstrated using the metastable framework ZIF-L as the model.

Rapid and scalable ruthenium catalyzed meta-C-H alkylation enabled by resonant acoustic mixing.

Project description:Synthetic chemistry approaches for direct C-H bond alkylation offers a promising alternative to traditional functional-group-centered strategies which often involve multi-step procedures and may suffer from a variety of challenges including scalability. Here, we introduce resonant mixing as an efficient method for meta-C-H alkylation of arenes using a Ru-catalyst, avoiding the need for bulk solvents, external temperature, or light. The described methodology is highly rapid, enabling multigram-scale synthesis of meta-alkylation products within a short reaction time and achieving a very high turnover frequency. The reaction operates via a radical mechanism and is characterized by its mild reaction conditions, substrate compatibility, and exceptional meta-selectivity, all while significantly reducing reaction times.

Rapid, Highly Sustainable Ring-Opening Polymerization via Resonant Acoustic Mixing.

Project description:Reported herein is the first combination of resonant acoustic mixing (RAM) and controlled ring-opening polymerization (ROP) to deliver fully sustainable, end-functionalized, biodegradable polymers via a manufacturing route with a much-reduced environmental impact. This includes the successful use of agriculturally sourced functionalized initiators (terpene alcohols) in ROP synthesis of cyclic esters to generate an array of novel, biodegradable polyesters applicable to numerous biomedical applications, such as drug delivery. Furthermore, RAM was utilized as a novel mixing technique, resulting in a synthetic process that was conducted: (a) with minimal use of toxic, flammable, costly, and environmentally detrimental solvents, (b) in the absence of organometallic catalysts, and (c) with significantly shorter ROP reaction times and temperatures. Consequent comparison with conventional magnetic stirring or sonication-based mixing methods showed that RAM allowed the more facile, kilogram-scale synthesis of polyesters via reactions conducted at room temperature rather than 150 °C and without the need for a metal catalyst. As a proof of concept, the polymers were used to encapsulate bovine serum albumin as a model protein, and its release was measured using an automated, high-throughput protein assay. This study demonstrated that the headgroup chemistry appears to affect the release rate of protein from the polymers.

Rapid acoustofluidic mixing by ultrasonic surface acoustic wave-induced acoustic streaming flow.

Project description:Ultrasonic surface acoustic wave (SAW)-induced acoustic streaming flow (ASF) has been utilized for microfluidic flow control, patterning, and mixing. Most previous research employed cross-type SAW acousto-microfluidic mixers, in which the SAWs propagated perpendicular to the flow direction. In this configuration, the flow mixing was induced predominantly by the horizontal component of the acoustic force, which was usually much smaller than the vertical component, leading to energy inefficiency and limited controllability. Here, we propose a vertical-type ultrasonic SAW acousto-microfluidic mixer to achieve rapid flow mixing with improved efficiency and controllability. We conducted in-depth numerical and experimental investigations of the vertical-type SAW-induced ASF to elucidate the acousto-hydrodynamic phenomenon under varying conditions of total flow rate, acoustic wave amplitude, and fluid viscosity conditions. We conducted computational fluid dynamics simulations for numerical flow visualization and utilized micro-prism-embedded microchannels for experimental flow visualization for the vertical SAW-induced ASF. We found that the SAW-induced vortices served as a hydrodynamic barrier for the co-flow streams for controlled flow mixing in the proposed device. For proof-of-concept application, we performed chemical additive-free rapid red blood cell lysis and achieved rapid cell lysis with high lysis efficiency based on the physical interactions of the suspended cells with the SAW-induced acoustic vortical flows. We believe that the proposed vertical-type ultrasonic SAW-based mixer can be broadly utilized for various microfluidic applications that require rapid, controlled flow mixing.

Acoustic Properties of Metal-Organic Frameworks.

Project description:Metal-organic frameworks (MOFs) have attracted significant attention in the past two decades due to their diverse physical properties and associated functionalities. Although numerous advances have been made, the acoustic properties of MOFs have attracted very little attention. Here, we systematically investigate the acoustic velocities and impedances of 19 prototypical MOFs via first-principle calculations. Our results demonstrate that these MOFs exhibit a wider range of acoustic velocities, higher anisotropy, and lower acoustic impedances than their inorganic counterparts, which are ascribed to their structural diversity and anisotropy, as well as low densities. In addition, the piezoelectric properties, which are intimately related to the acoustic properties, were calculated for 3 MOFs via density functional perturbation theory, which reveals that MOFs can exhibit significant piezoelectricity due to the ionic contribution. Our work provides a comprehensive study of the fundamental acoustic properties of MOFs, which could stimulate further interest in this new exciting field.

Resonant acoustic rheometry for non-contact characterization of viscoelastic biomaterials.

Project description:Resonant Acoustic Rheometry (RAR) is a new, non-contact technique to characterize the mechanical properties of soft and viscoelastic biomaterials, such as hydrogels, that are used to mimic the extracellular matrix in tissue engineering. RAR uses a focused ultrasound pulse to generate a microscale perturbation at the sample surface and tracks the ensuing surface wave using pulse-echo ultrasound. The frequency spectrum of the resonant surface waves is analyzed to extract viscoelastic material properties. In this study, RAR was used to characterize fibrin, gelatin, and agarose hydrogels. Single time point measurements of gelled samples with static mechanical properties showed that RAR provided consistent quantitative data and measured intrinsic material characteristics independent of ultrasound parameters. RAR was also used to longitudinally track dynamic changes in viscoelastic properties over the course of fibrin gelation, revealing distinct phase and material property transitions. Application of RAR was verified using finite element modeling and the results were validated against rotational shear rheometry. Importantly, RAR circumvents some limitations of conventional rheology methods and can be performed in a high-throughput manner using conventional labware. Overall, these studies demonstrate that RAR can be a valuable tool to noninvasively quantify the viscoelastic mechanical properties of soft hydrogel biomaterials.

Resonant acoustic rheometry for assessing plasma coagulation in bleeding patients.

Project description:Disordered hemostasis associated with life-threatening hemorrhage commonly afflicts patients in the emergency department, critical care unit, and perioperative settings. Rapid and sensitive hemostasis phenotyping is needed to guide administration of blood components and hemostatic adjuncts to reverse aberrant hemostasis. Here, we report the use of resonant acoustic rheometry (RAR), a technique that quantifies the viscoelastic properties of soft biomaterials, for assessing plasma coagulation in a cohort of 38 bleeding patients admitted to the hospital. RAR captured the dynamic characteristics of plasma coagulation that were dependent on coagulation activators or reagent conditions. RAR coagulation parameters correlated with TEG reaction time and TEG functional fibrinogen, especially when stratified by comorbidities. A quadratic classifier trained on selective RAR parameters predicted transfusion of fresh frozen plasma and cryoprecipitate with modest to high overall accuracy. While these results demonstrate the feasibility of RAR for plasma coagulation and utility of a machine learning model, the relative small number of patients, especially the small number of patients who received transfusion, is a limitation of this study. Further studies are need to test a larger number of patients to further validate the capability of RAR as a cost-effective and sensitive hemostasis assay to obtain quantitative data to guide clinical-decision making in managing severely hemorrhaging patients.

Therapeutic RNAi robed with ionic liquid moieties as a simple, scalable prodrug platform for treating skin disease.

Project description:The high prevalence of skin diseases and their visible symptoms result in major physical, emotional, and economic burden for which few solutions exist. To address this unmet medical need, topical delivery of RNAi such as siRNA holds many advantages including direct access to the diseased site, potent knockdown of disease symptoms, and limited off-target effects. Unfortunately, delivering drugs into skin is extremely difficult. To address these concerns, we present RNAi robed with ionic liquid moieties. Specifically, we show that robed-siRNAs can be synthesized by a simple two-step process from bulk materials. Robing affords tuneability of properties necessary for dermal drug delivery including octanol-water partitioning, skin transport, and cell internalization. The efficacy and safety of robed-siRNA for treating skin disease was confirmed by its ability to limit breakdown of elastin, a major cause of premature aging, following UVB exposure to human reconstructed skin tissue. Together, the data strongly support that therapeutic RNAi robed with ionic liquid moieties are a simple, scalable prodrug platform for treating skin disease.

Freely designable optical frequency conversion in Raman-resonant four-wave-mixing process.

Project description:Nonlinear optical processes are governed by the relative-phase relationships among the relevant electromagnetic fields in these processes. In this Report, we describe the physics of arbitrary manipulation of Raman-resonant four-wave-mixing process by artificial control of relative phases. As a typical example, we show freely designable optical-frequency conversions to extreme spectral regions, mid-infrared and vacuum-ultraviolet, with near-unity quantum efficiencies. Furthermore, we show that such optical-frequency conversions can be realized by using a surprisingly simple technology where transparent plates are placed in a nonlinear optical medium and their positions and thicknesses are adjusted precisely. In a numerical simulation assuming practically applicable parameters in detail, we demonstrate a single-frequency tunable laser that covers the whole vacuum-ultraviolet spectral range of 120 to 200 nm.

Elastometry of clot phantoms via magnetomotive ultrasound-based resonant acoustic spectroscopy.

Project description:Objective.An ultrasound-based system capable of both imaging thrombi against a dark field and performing quantitative elastometry could allow for fast and cost-effective thrombosis diagnosis, staging, and treatment monitoring. This study investigates a contrast-enhanced approach for measuring the Young's moduli of thrombus-mimicking phantoms.Approach.Magnetomotive ultrasound (MMUS) has shown promise for lending specific contrast to thrombi by applying a temporally modulated force to magnetic nanoparticle (MNP) contrast agents and measuring resulting tissue displacements. However, quantitative elastometry has not yet been demonstrated in MMUS, largely due to difficulties inherent in measuring applied magnetic forces and MNP densities. To avoid these issues, in this work magnetomotive resonant acoustic spectroscopy (MRAS) is demonstrated for the first time in ultrasound.Main results.The resonance frequencies of gelatin thrombus-mimicking phantoms are shown to agree within one standard deviation with finite element simulations over a range of phantom sizes and Young's moduli with less than 16% error. Then, in a proof-of-concept study, the Young's moduli of three phantoms are measured using MRAS and are shown to agree with independent compression testing results.Significance.The MRAS results were sufficiently precise to differentiate between thrombus phantoms with clinically relevant Young's moduli. These findings demonstrate that MRAS has potential for thrombus staging.

Eye orbit effects on eyeball resonant frequencies and acoustic tonometer measurements.

Project description:The eye orbit has mechanical and acoustic characteristics that determine resonant frequencies and amplify acoustic signals in certain frequency ranges. These characteristics also interfere with the acoustic amplitudes and frequencies of eyeball when measured with an acoustic tonometer. A model in which a porcine eyeball was embedded in ultrasonic conductive gel in the orbit of a model skull was used to simulate an in vivo environment, and the acoustic responses of eyeballs were detected. The triggering source was a low-power acoustic speaker contacting the occipital bone, and the detector was a high-resolution microphone with a dish detecting the acoustic signals without contacting the cornea. Dozens of ex vivo porcine eyeballs were tested at various intraocular pressure levels to detect their resonant frequencies and acoustic amplitudes in their power spectra. We confirmed that the eyeballs' resonant frequencies were proportional to intraocular pressure, but interference from orbit effects decreased the amplitudes in these resonant frequency ranges. However, we observed that the frequency amplitudes of eyeballs were correlated with intraocular pressure in other frequency ranges. We investigated eye orbit effects and demonstrated how they interfere with the eyeball's resonant frequencies and frequency amplitudes. These results are useful for developing advanced acoustic tonometer.
