Comparative study on the liquid desiccant dehumidi fi cation performance of lithium chloride and potassium formate

Liquid desiccant dehumidification is promising as it could be driven by renewable energy. In the present study, it newly investigated the dehumidification characteristics of KCOOH solution in an internally cooled dehumidifier. To select suitable concentration range, the vapor pressure of KCOOH solution with different solution concentration and temperature was measured with static method firstly. Then comparative experimental study was conducted to identify the dehumidification performance of KCOOH and LiCl solution under different solution and air flow rate, temperature and air humidity. Experimental results indicated that 70.3% KCOOH solution had almost the same vapor pressure as 35% LiCl solution. Under the same experimental conditions, the absolute moisture removal of 70.3% KCOOH solution was slightly higher than that of 35% LiCl solution as a result of the increased wetting area. It was found that the mass transfer coefficients of the two liquid desiccants were almost the same. An empirical correlation of Sh number was obtained to predict the mass transfer coefficient of KCOOH solution for dehumidification with a mean absolute relative deviation of 7.81%.

Coating of chromium and titanium carbide on diamond particles in molten LiCl-KCl-NaCl

Diamond particles were coated with chromium (Cr) or titanium (Ti) using a molten salt synthesis (MSS) approach involving lithium chloride (LiCl), potassium chloride (KCl), and sodium chloride (NaCl). Diamond and metal powders were heated at 700-900 degrees C in the MSS to create chromium carbide (Cr7C3) or titanium carbide (TiC) coatings on the diamond particles. Carbide formation was influenced by the dissolved metal content and the diffusion rate. The thickness and morphology of the Cr coating layer was not significantly affected by the molar ratio of the LiCl-KCl-NaCl mixture, however, in terms of the coating atmosphere, it is most valuable using the eutectic LiCl-KCl-NaCl mixture having the molar ratio of 55:33:12 and the lowest melting point. The resulting Cr7C3 and TiC coated surfaces and microstructures were characterized by X-ray diffraction and scanning electron microscopy, respectively. A uniform Cr7C3 and TiC layer formed on the surface of the diamond particles at a relatively low temperature, at which the graphitization of diamond was avoided. The coating layer thickness estimated by particle size analysis increased linearly with coating temperature. The thickness of the Cr- and Ti-coated layers ranged from 1 to 10 and 0.5-1.5 mu m, respectively, which indicated that the TiC coating formed at a much slower rate than the Cr7C3 coating.

Toluidine blue versus frozen section for assessment of mucosal tumor margins in oral squamous cell carcinoma

BackgroundWhen the resected specimen is sent for intraoperative margin assessment, all margins are grossly checked, and selected margins undergo a frozen section (FS) examination. Therefore, there is a possibility of sampling error. This study evaluated the effectiveness of using toluidine blue (TB) as an intraoperative triage screening tool to detect positive mucosal margins of the resected specimens of oral squamous cell carcinoma (OSCC) and serve as a guide for FS sampling.MethodsSurgical samples of 30 consecutive patients with biopsy-proven OSCC were included in the study. A total of 140 mucosal margins were analyzed intraoperatively by TB and FS, the results were compared with the final histopathology.ResultsOf the 140 examined mucosal tumor margins, 14 stained positives with TB, six were true-positives, eight were false-positives, and there were no false-negatives, as confirmed by final histopathology of the same margins. The diagnostic performance measures were sensitivity 100.0%; specificity 94.0%; positive predictive value (PPV) 42.9%; negative predictive value (NPV) 100.0%; and accuracy 94.3% (95% CI: 89.0-97.5%). For FS, there were three true-positives, three false-negatives, and no false-positives. The diagnostic performance measures were sensitivity 50.0%; specificity 100.0%; PPV 100.0%; NPV 97.8%; and accuracy 97.9% (95% CI: 93.9-99.6%).ConclusionTB is less specific but more sensitive than FS for detecting positive mucosal margins of resected OSCC. Screening the tumor mucosal margins with TB before FS sampling may help identify more tumor-bearing margins.Trial registrationThis trial was registered at ClinicalTrials.gov. Registration number: NCT03554967. Registration date: June 13, 2018.

Improving Hole-Conductor-Free Fully Printable Mesoscopic Perovskite Solar Cells’ Performance with Enhanced Open-Circuit Voltage via the Octyltrimethylammonium Chloride Additive

Hole-conductor-free fully printable mesoscopic perovskite solar cells (MPSCs) based on mp-TiO2/mp-ZrO2/carbon triple mesoscopic layers are competitive candidates among various rapidly developed PSCs for future photovoltaic applications due to the characteristics of low-cost, easy upscaling, and superior stability. However, the open-circuit voltage (V-OC) loss in printable MPSCs is relatively large compared to that in conventional PSCs, deteriorating the power conversion efficiency (PCE). Herein, the V-OC loss is reduced by the octyltrimethylammonium chloride (OTAC) additive. OTAC is found to upshift the Fermi level of TiO2 and passivate trap states in bulk MAPbI(3) perovskite, thus optimizing the energy-level alignment of the TiO2/perovskite heterojunction and suppressing nonradiative recombination in devices. As a result, MPSCs deliver the highest PCE of 16.53% with an improved V-OC of 1007 mV. The work demonstrates a facile strategy to reduce the V-OC loss in printable MPSCs by simultaneously optimizing the energy-level alignment and suppressing nonradiative recombination.

Investigation of brain damage mechanism in middle cerebral artery occlusion/reperfusion rats based on i-TRAQ quantitative proteomics

The objective of this study is to analyze the differential protein expression profile in cerebral cortex of rats with middle cerebral ischemia/reperfusion (MCAO/R), explore the brain damage mechanism of MCAO/R at protein level, and provide experimental foundation for searching specific marker proteins of MCAO/R. Rat model of MCAO/R was established by modified suture-occluded method, and the model was evaluated by the results of brain 2,3,5-triphenyltetrazolium chloride (TTC) and hematoxylin-eosin (HE) staining. Cerebral cortex of rats from sham-operated group (Sham) and MCAO/R groups was used for FASP enzymatic hydrolysis, i-TRAQ quantitative labeling, and reverse-phase liquid chromatography purification and separation. Orbitrap Q Exactive mass spectrometry was used for qualitative and quantitative analyses of total differential protein expression profiles. MCAO/R rats had obvious cerebral infarction lesions, and the relative surface area of cerebral infarction was significantly different compared with sham rats, suggesting that MCAO/R rat model was successfully prepared. There were 199 significant difference proteins (MCAO/R vs Sham, p < 0.05, |fold change|> 1.2), including 104 up-regulated proteins and 95 down-regulated proteins. Gene ontology (GO) enrichment analysis showed that the up-regulated proteins were mainly concentrated in the biological processes of positive regulation of NF-kappa B transcription and I-kappa B kinase-NF-kappa B, etc. Down-regulated proteins were mainly concentrated in long-term synaptic potentiation, cellular response to DNA damage stimulus, etc. KEGG pathway analysis showed that the pathway involved in differential proteins includes oxidative phosphorylation, metabolic pathway, and Ras signaling pathway. Network analysis of differential proteins showed that Alb, ndufb5, ndufs7, ApoB, Cdc42, Ndufa3, Igf1r, P4hb, Mbp, Gc, Nme1, Akt2, and other proteins may play an important role in regulating oxidative stress, apoptosis, and inflammatory response in MCAO/R. Quantitative proteomics based on i-TRAQ labeling reveals the effect of inflammation and apoptosis in brain damage mechanism of MCAO/R. Besides, this research provide some experimental foundation for search and determination of potential therapeutic targets of MCAO/R.

Poly-2-amino-benzonitrile, a wide dynamic pH linear responding material

In this paper, poly-2-Aminobenzonitrile (PABN), might be thinking as a functionalized polyaniline (PANI), is prepared and its application in the potentiometric pH sensor is demonstrated. The obtained PABN is characterized by FTIR, UV-Vis Spectra, XPS, SEM, BET surface area analysis, and BJH pore size and volume analysis. The pH sensors are characterized by an open circuit potential method with the two-electrode system. The experimental results demonstrate that the potentiometric pH sensors have the near Nernstian sensitivity of -52 mV/pH in the wide range of pH 1 to 13 in phosphate buffers. Prepared pH electrode has significantly lower potential deviation, fluctuation, drift, and hysteresis in sensitivity performances and proved to be the useful one for practical application with long-time stability and repeatability. Ion selectivity tests demonstrate the promising ion-selective electrode of PABN. This idea might be helpful to design functional polymers that have wide range of corresponding properties.

Embedded Cluster Study of the Co-Adsorption of HCl and H2O on PuO2 Surfaces

The simultaneous adsorption of HCl and H2O on the {111} and {110} surfaces of PuO2 has been studied using hybrid density functional theory within the periodic electrostatic embedded cluster method. A synergistic effect between co-adsorbed molecules is identified, such that HCl binding energies are enhanced by the presence of water. Higher levels of water also increase the HCl binding energy, forming very stable configurations on both surfaces for first-layer HCl interactions. Second-layer interactions are also explored, in which the HCl molecule is placed above a full monolayer of water on the surfaces. In such circumstances, the HCl reacts with a hydroxyl from the water monolayer to produce molecular water, with the chloride held to the surface via numerous chlorine-acceptor hydrogen bonds.
