Pressure Drop Measurements in Microfluidic Devices: A Review on the Accurate Quantification of Interfacial Slip (2021)

Abstract The correct theoretical definition of boundary conditions of flow underpins all fluid dynamics studies, and is particularly important in situations in which the flow is confined on the nano‐ and micro‐scale. Microfluidic devices are an excellent platform to measure boundary flow conditions, and the pressure drop versus flow rate method is particularly useful in detecting evidence of microscale interfacial slip and drag reduction. This review focuses on the pressure drop method, identifying the main experimental parameters affecting the accuracy and reproducibility of microfluidic experiments of slip, quantifying the magnitude and source of common errors, and providing practical solutions and guidelines. A summary of literature results of interfacial slip obtained with pressure drop measurements in microfluidic devices is also provided, and the slip results are directly compared to expected slip models. This review serves as an introduction for new researchers moving into the field of interfacial slip, and as reminder for established researchers of the need to create highly controlled experimental procedures in order to obtain reproducible and reliable measurements of boundary flow conditions. A direct comparison of accurate experiments with theoretical models is bound to bring about clarity about the mechanisms of slip on smooth and structured surfaces.
Analysis of rabbit tear proteins by high‐pressure liquid chromatography/electrospray ionization mass spectrometry (2003)

The aim of this study was to develop a fast and reliable analytical procedure for the display of the protein components of tears that can be used to differentiate the status of the ocular surface. Using this new procedure, we analyzed the tear protein components following a corneal wound in the rabbit. Calibrated 10-microL glass, fire-polished capillary micropipettes were used to collect tears from New Zealand White rabbits prior to and daily for 9 days following a unilateral 6-mm diameter centrally placed anterior keratectomy. Tear proteins were eluted by a reversed-phase high-performance liquid chromatography (RP-HPLC) column and the tear protein profile was monitored by electrospray ionization (ESI) mass spectrometry positive total ion current (TIC) chromatography. Tear proteins were reliably separated into 17 peaks, each of which contained one or a number of protein components. The molecular weight of each protein component was determined by on-line ESI. Major tear protein components, lactoferrin, lysozyme (minimally detectable in rabbit tears), albumin, lipocalin, lipophilin and beta2-microglobulin, were tentatively identified by this method. Based on the mass spectrometric data, beta2-microglobulin was found to be glycosylated with N-acetylhexosamine. ESI-positive TIC chromatograms and mass spectra revealed comparative differences in the tear protein spectra after corneal wounding. One day after wounding, rabbit lysozyme with a molecular weight of 14,717 Da was found to be 8-fold higher in the tears of wounded eyes when compared with tears from unwounded eyes. It dropped back to normal 3 days after wounding. The expression of an unidentified tear protein with the molecular weight of 16,060 Da was also elevated after corneal wounding and returned to normal level by day 5. In this study, LC/ESI-MS was developed as a fast, reproducible and simple method for the identification and analysis of many of the protein components of the tears. Importantly, this technique also allows quantification of each component resolved in the chromatogram. This method is very suitable for mapping peptides and proteins (<80 kDa) in tears.
A combined 2D-3D vision system for automatic robot picking (2014)

This paper presents a new vision technique for an industrial robot to pick up randomly placed workpieces. The proposed approach combines 2D and 3D vision for efficiently determining the spatial position of a target object in cluttered scenes. 2D vision permits to quickly detect and locate objects of interest, thus reducing significantly the processing time. The location of an extracted 2D region (a detected object) is then passed to the 3D vision module to determine its world coordinate. Finally the 3D position information is sent to the robot manipulator for automatic picking. The test results show the effectiveness of the proposed system.
Experimental and Modeling Study on Precipitation Kinetics of Silver in Nano and Micron Scale (2009)

In the present study, reaction crystallization of silver micron and nanoparticles was studied in a batch crystallizer in two different set of experiments by reducing silver in the presence or absence of sodium citrate. From the experimental determination of crystal size distribution, and with the aid of a mathematical model of the process, nucleation and growth kinetics of silver nanoparticles were determined. Kinetic parameters were determined by fitting the power law expression to the experimental data. Nanoparticle growth rates indicate a diffusion controlled mechanism with a first order dependence on supersaturation, while the observed low dependence of nucleation rate on magma density imply the primary nucleation occurring. Nevertheless, in the synthesis of micron particles magma density was important and agglomeration took place and nucleation, volume crystal growth rates as well as agglomeration kernel were determined.
Networked Low-Power Sensing: Network Interface and Main Operating System (2010)

The Defence Science and Technology Organisation has developed a low-power RS485 networked sensor interface for condition monitoring of structures, monitoring environments, or any other monitoring tasks. The core of the sensor interface consists of sensor invariant software and hardware and is based on the low-power Texas Instruments MSP430 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> series of micro-controllers. For any particular sensor(s), the interface consists of the core module which is linked to specific hardware and software for the sensor(s). Advantages of this approach are faster hardware and software development times and a consistent interface to any data logging or network control system. The core software manages communications, data logging, low-power modes, sensor addressing, the on-chip programmable memory (including the capability to modify the sensor interface software in the field), and a number of user accessible library routines (including full floating point calculations). An optional Secure Digital Card <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> (SDC <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> ) can be implemented allowing large amounts of data to be stored locally. The unit is 40 mm wide, 16 mm high, and typically 55-65 mm long, depending on the complexity of the sensors interface. This paper will present the design and characteristics of the core sensor interface with one example for a simple sensor interface.
Modeling IP Packets over WDM Ring Network with One Tunable Transmitter and Multiple Fixed Receivers (TT-FRs) * (2007)

This paper presents an optical network architecture for supporting the Internet pro- tocol (IP) packets directly over the wavelength division multiplexing (WDM) ring with one tunable transmitter and multiple fixed receivers (TT-FRs). A well-known access scheme based on carrier sense is adopted in this paper for all optical networks. An ap- proximate analysis, base on the M/G/1 queuing model, has been developed to evaluate the performance of the network. The analytical results show an excellent agreement with simulation results over a broad range of parameters. The results show that major part of the packet transfer delay is coming from the propagation delay from a source to a desti- nation. It is also observed that the throughput characteristic of the network depends upon the aggregated transmission capacity of the network. Both throughput and transfer delay improve with the number of wavelengths used in the ring, that proportional to the current escalation of WDM technology.
Human Mesenchymal Stem Cells Overexpressing the IL-33 Antagonist Soluble IL-1 Receptor–Like–1 Attenuate Endotoxin-Induced Acute Lung Injury (2013)

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are characterized by pulmonary edema attributable to alveolar epithelial-interstitial-endothelial injury, associated with profound inflammation and respiratory dysfunction. The IL-33/IL-1 receptor-like-1 (ST2) axis plays a key role in the development of immune-inflammatory responses in the lung. Cell-based therapy has been recently proposed as an effective alternative for the treatment of ALI and ARDS. Here, we engineered human adipose tissue-derived mesenchymal stem cells (hASCs) overexpressing soluble IL-1 receptor-like-1 (sST2), a decoy receptor for IL-33, in order to enhance their immunoregulatory and anti-inflammatory properties when applied in a murine ALI model. We administered both hASCs and hASC-sST2 systemically at 6 hours after intranasal LPS instillation, when pathological changes had already occurred. Bioluminescence imaging, immunohistochemistry, and focused transcriptional profiling confirmed the increased presence of hASCs in the injured lungs and the activation of an immunoregulatory program (CXCR-4, tumor necrosis factor-stimulated gene 6 protein, and indoleamine 2,3-dioxygenase up-regulation) in these cells, 48 hours after endotoxin challenge. A comparative evaluation of hASCs and the actions of hASC-sST2 revealed that local sST2 overproduction by hASC-sST2 further prevented IL-33, Toll-like receptor-4, IL-1β, and IFN-γ induction, but increased IL-10 expression in the injured lungs. This synergy caused a substantial decrease in lung airspace inflammation and vascular leakage, characterized by significant reductions in protein content, differential neutrophil counts, and proinflammatory cytokine (TNF-α, IL-6, and macrophage inflammatory protein 2) concentrations in bronchoalveolar lavage fluid. In addition, hASC-sST2-treated ALI lungs showed preserved alveolar architecture, an absence of apoptosis, and minimal inflammatory cell infiltration. These results suggest that hASCs genetically engineered to produce sST2 could become a promising therapeutic strategy for ALI/ARDS management.
A High-resolution Vector-imaging Condition for Elastic Reverse-time Migration (2008)

We introduce a new vector-imaging condition for elastic reverse-time migration to produce high-resolution migration images. This new imaging condition is developed by the use of polarization vectors of wave fields along with the conventional imaging condition. The conventional imaging condition as that used for scalar-wave migration, is established on the principle that incident and reflected waves coincide in phase at a reflection point. Our vector-imaging condition also makes use of directional coincidence of the forward and backward propagating elastic waves. The polarization vectors of elastic wave fields are obtained by spatial derivatives of the corresponding waves in the frequency domain. We demonstrate using synthetic examples that the use of polarization vectors in the imaging condition significantly improves migration images. Elastic-wave reverse-time migration with the new vector-imaging condition will enable us to reliably image complex subsurface structures, particularly for true-amplitude migration.

Abstract To reduce the production cost of reflective TFT‐LCDs, we have developed a method of fabricating TFT‐LCDS that is comprised of only four photo mask processes. Experimental black and white reflective LCDs fabricated with this method exhibit a lightness (L*) of 83, and no image parallax.
Evaluation of the Magnetostrictive Properties of Hiperco (1950)

The magnetostrictive properties of Hiperco, a magnetic alloy of iron, cobalt, and chromium, were investigated to determine its suitability as a material for electromechanical transducers. The relations between the magnetic and magnetostrictive characteristics of a material and its performance as a transducer element are reviewed and criteria for its evaluation established. The properties of Hiperco, measured after a suitable heat treatment had been determined, are discussed in relation to these criteria and a comparison made with nickel and Permendur. For operation at magnetic remanence Hiperco is shown to be as good as Permendur for hydrophone applications, but inferior to nickel and Permendur when used as an underwater projector at high power levels. When polarized above remanence maximum value of 0.17 for the electromechanical coupling coefficient is realized and operation as a projector is improved. Performance data are given for a small underwater transducer constructed of Hiperco operating at remanence.

Catalytic Sulfoxidation and Epoxidation with a Mn(III) Triazacorrole:  Evidence for A “Third Oxidant” in High-Valent Porphyrinoid Oxidations (2003)

The reaction between (TBP)8(Cz)Mn(III) (1) and the oxygen atom donors iodosylbenzene (PhIO) or p-cyanodimethylaniline-N-oxide (CDMANO) leads to the manganese(V)-oxo complex (TBP)8(Cz)Mn(V)O (2), which has been isolated and characterized previously. Under catalytic conditions with 1 as added catalyst and PhIO as oxidant, both sulfoxidation of PhSMe and epoxidation of cis-stilbene is observed, whereas with CDMANO no sulfoxidation takes place, suggesting that 2 is not the active oxidant. Examination of the independent reactivity of isolated 2 toward PhSMe and cis-stilbene supports this conclusion. A mechanism which relies on a novel type of oxidant involving Lewis acid activation of PhIO by the Mn(V)-oxo complex 2 accounts for these observations and is confirmed by 18O-labeling experiments.

Nonlinear minimum-time feedforward control for output transition with pre- and post-actuation (2010)

This article poses and solves the time-optimal output transition problem to change the system output, from an initial value to another for invertible nonlinear systems. The main contribution of the article is to show that the use of pre- and post-actuation input outside the transition interval can reduce the transition time beyond the standard bang-bang-type inputs for optimal state transition. The approach is illustrated with a nonlinear example.
A Step Forward in Understanding the Hydrogen Adsorption and Compression on Activated Carbons (2021)

Hydrogen adsorption on activated carbons (ACs) is a promising alternative to compression and liquefaction for storing hydrogen. Herein, we have studied hydrogen adsorption on six commercial ACs (CACs) with surface areas ranging from 996 to 2216 m<sup>2</sup> g<sup>-1</sup> in a temperature range of 77 to 273 K and pressures up to 15 MPa. Excess hydrogen adsorption capacities of 2.3 to 5.8 wt % were obtained at 77 K and 4 MPa. We demonstrated that, contrary to what is normally done, hydrogen capacity is more accurately predicted by the surface area determined by the nonlocal density functional theory method applied to N<sub>2</sub> and CO<sub>2</sub> adsorption data than by the Brunauer-Emmett-Teller (BET) area. The modified Dubinin-Astakhov (MDA) equation was used to fit the experimental adsorption data, and the relationship between the MDA parameters (<i>n</i><sub>max</sub>, <i>V</i><sub>a</sub>, α, and β) and the textural properties of the CACs was determined for the first time. We concluded that the <i>n</i><sub>max</sub> and <i>V</i><sub>a</sub> parameters are related to the BET area, while the α and β parameters are related to the average micropore size and total pore volume, respectively. α and β were used to evaluate the enthalpy and entropy of adsorption and we show that these parameters can be used to assess the best carbon for hydrogen storage or compression.
