Rapid production of kilogram-scale graphene nanoribbons with tunable interlayer spacing for an array of renewable energy (2023)

Graphene nanoribbons (GNRs) are widely recognized as intriguing building blocks for high-performance electronics and catalysis owing to their unique width-dependent bandgap and ample lone pair electrons on both sides of GNR, respectively, over the graphene nanosheet counterpart. However, it remains challenging to mass-produce kilogram-scale GNRs to render their practical applications. More importantly, the ability to intercalate nanofillers of interest within GNR enables in-situ large-scale dispersion and retains structural stability and properties of nanofillers for enhanced energy conversion and storage. This, however, has yet to be largely explored. Herein, we report a rapid, low-cost freezing-rolling-capillary compression strategy to yield GNRs at a kilogram scale with tunable interlayer spacing for situating a set of functional nanomaterials for electrochemical energy conversion and storage. Specifically, GNRs are created by sequential freezing, rolling, and capillary compression of large-sized graphene oxide nanosheets in liquid nitrogen, followed by pyrolysis. The interlayer spacing of GNRs can be conveniently regulated by tuning the amount of nanofillers of different dimensions added. As such, heteroatoms; metal single atoms; and 0D, 1D, and 2D nanomaterials can be readily in-situ intercalated into the GNR matrix, producing a rich variety of functional nanofiller-dispersed GNR nanocomposites. They manifest promising performance in electrocatalysis, battery, and supercapacitor due to excellent electronic conductivity, catalytic activity, and structural stability of the resulting GNR nanocomposites. The freezing-rolling-capillary compression strategy is facile, robust, and generalizable. It renders the creation of versatile GNR-derived nanocomposites with adjustable interlay spacing of GNR, thereby underpinning future advances in electronics and clean energy applications.
Heterophasic copolymers of polypropylene: Development, design principles, and future challenges (2013)

ABSTRACT Initially developed to overcome the limited low‐temperature impact resistance of polypropylene (PP) and allow its application in subzero temperatures, the PP/elastomer blends became a very important and industrially relevant material class. Within the last 40 years, a whole range of PP impact copolymers from multireactor processes have been developed that are capable of covering wide application areas. This review summarizes their developmental history and presents options for the in‐reactor design of these polymers and their modification by compounding with elastomers and fillers or reinforcements after the polymerization. An overview of the application range is also presented together with a glimpse into the future of this material class. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 130: 3028–3037, 2013
Mycoplasma bovoculi infection increases ocular colonization by Moraxella ovis in calves (1986)

To determine whether infection with Mycoplasma bovoculi increases ocular colonization of cattle eyes with Moraxella bovis and other bacteria, colonization of ocular gram-negative bacteria were measured in eyes of cattle infected with Mycoplasma bovoculi. Strains of Moraxella ovis were chosen because these are among the most commonly isolated species of gram-negative bacteria from cattle eyes. Five strains of M ovis were characterized biochemically and by pilus structure, permitting the recognition of 2 biotypes. All strains were tested in a mouse corneal pathogenicity model. One strain of each biotype was selected for testing in calves. All 5 strains were apathogenic for mice, and the 2 strains tested in cattle did not induce keratitis. Infection of calves with Mycoplasma bovoculi increased the amount and persistence of colonization with the strains of M ovis.
Self-Assembly of Pyrrole-Ferrocene Hybrids, Determined Inter Alia by a New Chemically Induced Electrospray Mass Spectrometry Technique (1998)

An interesting example of a noncovalently linked organometallic superstructure (shown right) is obtained from the self-assembly of tetrapyrrole-substituted ferrocene. As a result of the self-associating properties of the pyrrole–ester subunits, this system forms ribbon-like infinite chains in the solid state and small but well-characterized oligomers in organic solvents. Selective oxidation of the ferrocene moiety provides a cationic ferrocenium species amenable to electrospray mass spectrometric analysis.
Hyperresponsiveness of Migraine Patients to the Hypotensive Action of Bromocriptine (1980)

SYNOPSIS Migraine frequently induces hypotension, which has a large postural component. Since pain and other symptoms of the migraine syndrome have been suggested to be central in nature, an involvement of the dopaminergic pathways within the central nervous system that mediate hypotensive responses, might be postulated in migraine patients. In the study, a test dose (2.5 mg) of bromocriptine, a brain dopamine agonist, induced an intense hypotensive reaction in migraineurs, but not in controls. During bromocriptine‐induced hypotension, serum dopamine β‐hydroxylase activity did not change. The fall of blood pressure, due to bromocriptine, in migraine patients could be considered as an indirect expression of brain dopamine receptor supersensitivity caused by a deficiency of dopamine and or endogenous morphine‐like substances. This mechanism is compatible with the hypothesis which considers migraine as a clinical condition of chronic natural opioid abstinence.
Oral acetylcysteine reduces exacerbation rate in chronic bronchitis: report of a trial organized by the Swedish Society for Pulmonary Diseases. (1983)

This multicentre trial was undertaken to confirm previous results indicating that long-term treatment with oral acetylcysteine reduces the exacerbation rate in patients with chronic bronchitis. Two hundred and eighty-five patients, smokers or ex-smokers, with chronic bronchitis started a pre-trial placebo-period of 1 month. After this run-in period 259 patients were included in the trial and randomized into two parallel groups. The patients were treated in a double-blind way either with acetylcysteine 200 mg b.i.d. or placebo b.i.d. for 6 months. The trial was completed by 98 patients in the acetylcysteine group and by 105 patients in the placebo group. Initially, there were no significant differences between the groups. Twice weekly, the patients filled in a diary card concerning symptoms. The number of exacerbations was assessed from these cards and at visits 2, 4 and 6 months after institution of therapy. The exacerbation rate was significantly lower in the acetylcysteine group in which 40% of the patients remained free from exacerbations compared to 19% in the placebo group. Sick-leave due to acute exacerbation was significantly less common in the acetylcysteine group. The drug was well tolerated.
Imaging of Abdominal Manifestations of Melanoma (1998)

Despite an increasing incidence of melanoma in this country, innovative new therapies are allowing patients to receive aggressive experimental treatments. Diagnostic imaging remains crucial for tumor staging and for follow-up of patients being treated with these protocols. Because metastases occur in the abdomen and pelvis in approximately 60% of patients, it is important to accurately identify all sites of tumor spread. A variety of imaging techniques are used to image these patients, with CT currently being used for staging purposes and to guide diagnostic biopsies. Other imaging techniques, such as MR, ultrasound, and fluoroscopy, are currently reserved for investigating specific complications of melanoma, such as vascular invasion, hemorrhage from a tumor, and small bowel involvement, including intussusception. Recently, whole body positron emission tomography (PET) imaging using 2-deoxy-2-fluoro-D-glucose (FDG) has been shown to be highly accurate in assessing patients with metastatic malignant melanoma. This review illustrates the spectrum of manifestations of metastatic melanoma throughout the abdomen and pelvis, including solid organ, hollow lumen, and retroperitoneal involvement, and demonstrates some of the typical and atypical manifestations that may be identified.
MicroRNA Classifiers for Predicting Prognosis of Squamous Cell Lung Cancer (2009)

Non-small cell lung cancer (NSCLC), which is comprised mainly of adenocarcinoma and squamous cell carcinoma (SCC), is the cause of 80% of all lung cancer deaths in the United States. NSCLC is also associated with a high rate of relapse after clinical treatment and, therefore, requires robust prognostic markers to better manage therapy options. The aim of this study was to identify microRNA (miRNA) expression profiles in SCC of the lung that would better predict prognosis. Total RNA from 61 SCC samples and 10 matched normal lung samples was processed for small RNA species and profiled on MirVana miRNA Bioarrays (version 2, Ambion). We identified 15 miRNAs that were differentially expressed between normal lung and SCC, including members of the miR-17-92 cluster and its paralogues. We also identified miRNAs, including miR-155 and let-7, which had previously been shown to have prognostic value in adenocarcinoma. Based on cross-fold validation analyses, miR-146b alone was found to have the strongest prediction accuracy for stratifying prognostic groups at approximately 78%. The miRNA signatures were superior in predicting overall survival than a previously described 50-gene prognostic signature. Whereas there was no overlap between the mRNAs targeted by the prognostic miRNAs and the 50-gene expression signature, there was a significant overlap in the corresponding biological pathways, including fibroblast growth factor and interleukin-6 signaling. Our data indicate that miRNAs may have greater clinical utility in predicting the prognosis of patients with squamous cell lung carcinomas than mRNA-based signatures.
Controlling harmonic instability of HDVC links connected to weak AC systems (1990)

The effectiveness of providing positive damping of harmonic oscillations by either modifying the AC-system filter characteristics or adding to the rectifier control circuitry are examined. Two alternative measures of controlling harmonic instability are investigated: the use of C-type AC filters, and a simple addition of a harmonic damping circuit in the rectifier converter control. The design of a C-type filter is presented and its effectiveness described. Harmonic damping by controls consists of taking the output from a fast-response DC current transducer, passing it through a filter and a gain, and adding the output to the firing-angle order. Both methods result in stable recovery from faults at both rectifier and inverter terminal busbars for a DC system inherently harmonically unstable.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Alleviation of DSS-induced colitisvia Lactobacillus acidophilustreatment in mice (2020)

Gut microbiota play a major role in host physiology and immunity. Inflammatory bowel diseases (IBDs), the important immune-related diseases, can occur through immune system malfunction originating due to dysregulation of the gut microbiota. The aim of this study was to investigate the capabilities and mechanisms of Lactobacillus acidophilus (L. acidophilus) KBL402 and KBL409 treatment in the alleviation of colitis using the in vivo dextran sodium sulfate (DSS)-induced colitis mice model. Various colitis symptoms of mice, including disease activity index score [4.55 ± 0.99 (P < 0.001) and 5.12 ± 0.94 (P < 0.001), respectively], colon length [6.18 ± 0.43 mm (P < 0.001) and 6.62 ± 0.47 mm (P < 0.001), respectively], and colon histological score [(5.33 ± 1.03 (P < 0.001) and 4.00 ± 0.89 (P < 0.01), respectively)], were significantly restored with L. acidophilus KBL402 or KBL409 administration (1 × 10<sup>9</sup> colony-forming units) for 8 days. Moreover, inflammatory cytokines, chemokines, and myeloperoxidase were downregulated in mice with L. acidophilus treatment. Upregulation of anti-inflammatory cytokine IL-10 or regulatory T cells were discovered with L. acidophilus KBL402 (12.90 ± 7.87 pg mL<sup>-1</sup>) (P < 0.05) or L. acidophilus KBL409 treatment (10.63 ± 2.70%) (P < 0.05), respectively. Expressions of inflammation-related micro-RNAs (miRs) were also significantly altered in mice with L. acidophilus. Finally, L. acidophilus treatment could restore the diversity of the gut microbiota. Mice with L. acidophilus KBL402 treatment showed a high relative abundance of the genus Akkermansia (0.022 ± 0.017) and Prevotella (0.010 ± 0.006) (P < 0.01). Butyrate and propionate, the major short-chain fatty acids, in the ceca of DSS + KBL402-treated mice were significantly higher than in that of the mice with DSS-induced colitis (0.03 ± 0.02 ng mg<sup>-1</sup> and 0.03 ± 0.01 ng mg<sup>-1</sup>, respectively) (P < 0.05). Our study suggests that L. acidophilus KBL402 and KBL409 could be useful for the prevention or treatment of IBDs in various ways including the modulation of immune responses and miR expression, restoration of the gut microbiota, and production of metabolites.

α-Fe2O3 nanotubes-reduced graphene oxide composites as synergistic electrochemical capacitor materials (2012)

We present a facile approach for the fabrication of a nanocomposite comprising α-Fe(2)O(3) nanotubes (NTs) anchored on reduced graphene oxide (rGO) for electrochemical capacitors (ECs). The hollow tubular structure of the α-Fe(2)O(3) NTs presents a high surface area for reaction, while the incorporation of rGO provides an efficient two-dimensional conductive pathway to allow fast, reversible redox reaction. As a result, the nanocomposite materials exhibit a specific capacitance which is remarkably higher (~7 times) than α-Fe(2)O(3) NTs alone. In addition, the nanocomposites show excellent cycling life and large negative potential window. These findings suggest that such nanocomposites are a promising candidate as negative electrodes in asymmetrical capacitors with neutral electrolytes.

Computer and telecommunications equipment room cooling: a review of literature (2003)

Due to technology compaction, the information technology (IT) industry has seen a large increase in power density and heat dissipation within the footprint of computer and telecommunications hardware. The heat dissipated in these systems is exhausted to the room and the room has to be maintained at acceptable temperatures for reliable operation of the equipment. Cooling computer and telecommunications equipment rooms is becoming a major challenge. This paper reviews the literature dealing with various aspects of cooling computer and telecommunications equipment rooms. Included are papers on experimental work analyzing cooling schemes, numerical modeling, energy saving schemes, natural convection room cooling, forced convection room cooling, cooling raised floor versus nonraised floor type installations, and other related areas.
Galectin 3 aggravates joint inflammation and destruction in antigen‐induced arthritis (2010)

Our findings show that galectin 3 plays a pathogenic role in the development and progression of AIA and that the disease severity is accompanied by alterations of antigen-specific IgG levels, systemic levels of TNFα and IL-6, and frequency of IL-17-producing T cells. To our knowledge, this is the first report of in vivo evidence that galectin 3 plays a crucial role in the development of arthritis.
A Novel Voltage Reconstruction Method for MRAS based Sensorless IPMSM Drives (2021)

Different advanced sensorless techniques have been proposed based on the model reference adaptive system (MRAS) principle to make the interior permanent magnet synchronous motor (IPMSM) drives mechanically more robust. However, in the special application such as high-power traction systems, the difference between the switching frequency and the calculation frequency is large, and the inconsistency between the command voltage and the actual voltage will affect the accuracy of the MARS estimator. To overcome such a drawback, this paper proposes a novel voltage reconstruction method to improve the accuracy of the MRAS estimator. Simulations and experiments are conducted to verify the effectiveness of the proposed method. Combining with the proposed algorithm, the problem of the inconsistency can be solved, and an accurate rotation estimation can be realized.
Adaptive Distributed Beamforming for Amplify-and-Forward Relay Networks: Convergence Analysis (2014)

For wireless amplify-and-forward (AF) relay networks, this work focuses on the convergence analysis of adaptive distributed beamforming schemes that can be reformulated as local random search algorithms via a random search framework. It is proved that under two sufficient conditions: 1) the objective function of the random search algorithm is continuous and all its local maxima are global maxima in the considered feasible set, and 2) the origin is an interior point within the support of the probability measure for the random perturbation, the corresponding adaptive distributed beamforming schemes converge almost surely. While the second sufficient condition can be controlled by system designer and satisfied with relative ease, the first sufficient condition initially seems strict. Surprisingly, further analysis on the signal-to-noise ratio (SNR) functions in AF relay networks with individual and total power constraints demonstrates that, in both scenarios, local maxima are global maxima and hence, the first sufficient condition is satisfied. Finally, the proposed framework was extended to analyze adaptive distributed beamforming schemes in an asynchronous setting, and simulation results were provided to further validate our analysis.
SiOC Ceramic Monoliths with Hierarchical Porosity (2009)

SiOC glass monoliths possessing hierarchical porosity were produced by a one‐pot processing method. Periodic mesoporous organosilica (PMO) particles were embedded into a foamed siloxane preceramic polymer. After pyrolysis at 1000°C in inert atmosphere, open celled, permeable SiOC ceramic monoliths with a high amount of pores, ranging in size from hundred of micrometers to a few nanometers, were obtained. The components possessed a specific surface area of 137 m 2 /g, indicating the retention of most of the mesopores after the pyrolytic conversion of the PMO precursor particles. These fillers converted to truncated rhombic dodecahedral SiOC mesoporous micron‐sized grains, homogeneously distributed throughout the SiOC cellular matrix. The produced porous ceramics possessed compression strength of about 1.7 MPa, which is adequate for their use in several engineering applications.

Large field of view aberrations correction with deformable lenses and multi conjugate adaptive optics (2023)

Optical microscopes can have limited resolution due to aberrations caused by samples and sample holders. Using deformable mirrors and wavefront sensorless optimization algorithms can correct these aberrations, but the correction is limited to a small area of the field of view. This study presents an adaptive optics method that uses a series of plug-and-play deformable lenses for large field of view wavefront correction. A direct wavefront measurement method using the spinning sub-pupil aberration measurement technique is combined with correction based on the deformable lenses. Experimental results using fluorescence microscopy with a wide field and a light sheet fluorescence microscope show that the proposed method can achieve detection and correction over an extended field of view with a compact transmissive module placed in the detection path of the microscope. This method could improve the resolution and accuracy of imaging in a variety of fields, including biology and materials science.
