Caltrop particles synthesized by photochemical reaction induced by X-ray radiolysis

X-ray radiolysis of a Cu(CH3COO)2 solution was observed to produce caltrop-shaped particles of cupric oxide (CuO, Cu2O), which were characterized using high-resolution scanning electron microscopy and micro-Raman spectrometry. X-ray irradiation from a synchrotron source drove the room-temperature synthesis of submicrometer- and micrometer-scale cupric oxide caltrop particles from an aqueous Cu(CH3COO)2 solution spiked with ethanol. The size of the caltrop particles depended on the ratio of ethanol in the stock solution and the surface of the substrate. The results indicated that there were several synthetic routes to obtain caltrop particles, each associated with electron donation. The technique of X-ray irradiation enables the rapid synthesis of caltrop cupric oxide particles compared with conventional synthetic methods.

Researchers at the University of Texas Dallas (UTD) are playing with alchemy by transforming a virus into an organic radical contrast agent (ORCA), an alternative to gadolinium-based contrast agents to be used in magnetic resonance imaging (MRI) procedures. ORCA molecules had been previously considered too dim for scanning and were easily eradicated by vitamin C in the body. UTD researchers found that by connecting the molecules to a  tobacco mosaic virus, a virus that attacks plant cells and disrupts cell activity, they were able to eliminate those issues and make the ORCA an effective agent. Once the ORCA ...

Conclusions: The maximum length of the coracoid available for transfer in Malasian Malay patients was less than what has been recommended in the literature for the Latarjet procedure. The surface area that would be increased after a coracoid graft is placed on the glenoid would be 12.4±1.8 mm. Knowledge obtained from this study may help us further optimize osseous considerations for the Latarjet procedure in the Malaysian Malay population. Level of Evidence: Level III.

AbstractObjectivesTo test if the partially digital workflow by digitalisation of the impression reveals a comparable accuracy as the indirect digitalisation of the gypsum cast for 4-unit fixed dental prostheses (FDPs).Materials and methodsA titanium model with a tapered full veneer preparation of a molar and premolar was used as analysis model. To receive a virtual three-dimensional reference dataset (REF), it was digitised by industrial computed tomography. Three impression materials were used with individual impression trays (N = 36,n/material  = 12): (1) PE (Impregum Penta), (2) PVS-I (Imprin...

ConclusionsThe present study demonstrated the reproducibility of a scientific concept (reduction in RCF produces PRF clots with more evenly distributed cells and growth factors) utilizing different devices. Furthermore, (and until now overlooked), it was revealed for the first time that the centrifugation tubes are central to the quality production of PRF. Future research investigating tube characteristics thus becomes critically important for the future optimization of PRF.Clinical relevanceThis is the first study to reveal the marked impact of centrifugation tubes on the final production of PRF. Future study thus becomes...

Abstract In the presented work, we proposed the use of polyvinylidene difluoride (PVDF) as a coupling agent to load MIL-101(Cr) and carboxylated multi-walled carbon nanotubes (MWCNTs) on the skeleton of melamine sponge (MeS) for the preparation of novel extraction media with high-efficiency. The morphology and structure of this composite were characterized by scanning electron microscopy (SEM) analyses. The obtained MIL-101(Cr)/MWCNTs functionalized MeS(MIL/M-MeS) cube was used as a sorbent for the solid-phase extraction (SPE) of six triazines (Atraton, Simetryne, Prometon, Ametryn, Propazine, and Prometryn) spike...

In this study, we report a novel ZnO/polyaniline (PANI) nanocomposite optical gas sensor for the determination of acetic acid at room temperatures. ZnO nanorods, synthesized in powder form were coated by PANI (ZnO/PANI) by chemical polymerization method. The obtained nanocomposites were deposited on glass substrate and dried overnight at room temperature. Structure and optical properties of ZnO/PANI nanocomposite have been studied by using X-ray diffraction, transmission electron microscopy, scanning electron microscopy, diffuse reflectance and photoluminescence spectroscopy. Tests towards acetic acids were performed in th...

Abstract The ability to acquire high-quality spatially-resolved mass spectrometry data is sought in many fields of study, but it often comes with high cost of instrumentation and a high level of expertise required. In addition, techniques highly regarded for isotopic analysis applications such as thermal ionization mass spectrometry (TIMS) do not have the ability to acquire spatially-resolved data. Another drawback is that for radioactive materials, which are often of interest for isotopic analysis in geochemistry and nuclear forensics applications, high-end instruments often have restrictions on radioactivity and...

Abstract Microbiological and electrochemical assays, applying the cylinder-plate and differential pulse voltammetry as techniques, are reported for the quantitative determination of roxithromycin in serum and solid pharmaceutical form. The microbiological assay is based upon the inhibitory effect of this drug on the strain Bacillus subtilis ATCC 9372 used as the test microorganism. Linearity of the calibration curve was observed over the concentration range of 8.37-83.70 μg mL-1, with relative standard deviation values less than 5.0%. The electrochemical behavior of roxithromycin was studied at a grap...

In this study, we used a different iodine isotype (nat/124/125I) to label JS001 probes to target the human PD1 (hPD1) antigen. In vitro, the half maximal effective concentration (EC50) value of natI-JS001 did not significantly differ from that of JS001. The uptake of 125I-JS001 by activated T cells was 5.63 times higher than that by nonactivated T cells after 2 h of incubation. The binding affinity of 125I-JS001 to T cells of different lineages after phytohemagglutinin (PHA) stimulation reached 4.26 nmol/L. Humanized PD1 C57BL/6 mice bearing mouse sarcoma S180 cell tumors were validated for immuno-positron emission tomogra...
