MXene/CNTs films prepared by electrophoretic deposition for supercapacitor electrodes

Publication date: Available online 11 October 2018Source: Journal of Electroanalytical ChemistryAuthor(s): L. Yang, W. Zheng, P. Zhang, J. Chen, W.B. Tian, Y.M. Zhang, Z.M. SunAbstractBinder-free Ti3C2 MXene/carbon nanotubes (Ti3C2/CNTs) films were successfully deposited onto graphite paper via electrophoretic deposition (EPD) method for supercapacitor electrodes. The as-prepared Ti3C2/CNTs electrode exhibits enhanced specific capacitance, approximately 1.5 times and 2.6 times of that of pristine Ti3C2 and CNTs films, respectively. Impressively, Ti3C2/CNTs electrodes demonstrate excellent cycling stability, without capacitance decay over 10,000 cycles. Incorporation of CNTs into MXene builds a robust structure, preventing MXene from restacking, and thus leading to the enhanced electrochemical performance. These results suggest that robust Ti3C2/CNTs films can be prepared by a simple yet effective EPD method, potentially applicable to other hybrid MXene systems.

ConclusionsResults suggest that the novel exposure approach may decrease social distress, but not necessarily influence speech fluency. These findings underscore the importance of the assessment and treatment of SAD among adults who stutter and suggest that the integration of care between clinical psychologists and speech-language pathologists may prove beneficial for this population.

Publication date: March 2019Source: Safety Science, Volume 113Author(s): Tao Yang, Peng Chen, Bo Li, Baisheng Nie, Chuanjie Zhu, Qiusheng YeAbstractThe mechanism of gas adsorption and desorption is very important for mine safety. Meanwhile, the gas adsorption or desorption process may lead to temperature or heat variation. In order to reveal this phenomenon, the relationship between gas adsorption (and desorption) and temperature of three different coal samples was experimentally investigated under different temperatures, coal ranks and equilibrium pressures. It’s found that gas adsorption quantity, gas adsorption ra...

In this paper we present a range of mathematical programming models and a workflow that support decision makers in planning an emergency response system. For the models that are difficult to solve directly, we introduce a tailor-made solution method. With respect to the optimization objectives and constraints, we pa...

Hereditary forms of distal renal tubular acidosis (dRTA) are rare and mainly caused by mutations in ATP6V1B1, ATP6V0A4 and SLC4A1. About 20 mutations in SLC4A1 gene have been found that are related to either autosomal dominant (AD) or autosomal recessive dRTA. AD dRTA often manifest as constitutional and can easily be delayed in diagnosis and treatment. A 30-year-old male patient has a history of paroxysmal paralysis for 7 years, presenting with mild hypokalemia, alkalization of urine, normal blood PH value and increased urinary calcium. Patient ’s father has similar presentations but never came to the hospital. We f...

Mutations in theCTNS gene encoding the lysosomal membrane cystine transporter cystinosin are the cause of cystinosis, an autosomal recessive lysosomal storage disease. More than 140CTNS mutations have been reported worldwide. Recent studies have discovered that cystinosin exerts other key cellular functions beyond cystine transport such as regulation of oxidative state, lysosomal dynamics and autophagy. Here, we review the different mutations described in theCTNS gene and the geographical distribution of incidence. In addition, the characteristics of the various mutations in relation to the functions of cystinosin needs to...

Context: Human kidney organoids are complex structures resembling nephron arrays, which can be derived in a variety of ways. Whether all of these differentiation protocols produce qualitatively similar organoid cell types is not yet clear.Subject of Review: A comparative analysis of 2 organoid differentiation protocols is recently reported inCell Stem Cell [Wu et al.: Cell Stem Cell 2018;pii:S1934-5909(18)30491-0], using single cell RNA sequencing (scRNA-seq) as an analytical tool. This demonstrates that the 2 protocols have much in common, and that neither produces kidney cells in a pure or comprehensive manner. Ureteric ...
