Highly Oriented WS Monolayers for High-Performance Electronics.

2D transition-metal dichalcogenide (TMDC) semiconductors represent the most promising channel materials for post-silicon microelectronics due to their unique structure and electronic properties. However, it remains challenging to synthesize wide-bandgap TMDCs monolayers featuring large areas and high performance simultaneously. Herein, highly oriented WS monolayers are reproducibly synthesized through a templated growth strategy on vicinal C/A-plane sapphire wafers.

Performance limit of all-wrapped monolayer MoS transistors.

All-wrapped transistors consisting of two-dimensional transition-metal dichalcogenide channels are appealing candidates for post-silicon electronics. Based on the Boltzmann transport theory, here we report a comprehensive theoretical survey on the performance limits for monolayer MoS transistors with three prototypical gate dielectrics (AlO, HfO and BN), by including primary extrinsic charge scattering mechanisms present in practical devices. A concept of "dead space" between the dielectrics and channels is proposed and used in calculation to ameliorate the general overestimation in scattering intensity of surface optical phonons, which enables an accurate description of electronic transport behavior.

Prognostic role of SPRY4-IT1 in female breast carcinoma and malignant tumors of the reproductive system: A meta-analysis.

Background: The prognostic value of SPRY4-Intronic transcript 1 (SPRY4-IT1) in women suffering from breast carcinoma and malignant tumors of the reproductive system remains to be ascertained. Therefore, this paper attempted to assess the relationship between SPRY4-IT1 with the clinicopathological indicators and survival analysis in women suffering from breast carcinoma and malignant tumors of their reproductive organs through meta-analysis.

Method: Related literature retrieved from Cochrane Library, Ovid, Embase, PubMed, the CNKI, and the Web of Science databases were reviewed.

Clinicopathological significance of epidermal growth factor receptor expression in papillary thyroid carcinoma: a meta-analysis.

Introduction: This study aimed to determine the relationship between the expression of epidermal growth factor receptor (EGFR) and pathological indicators in papillary thyroid carcinoma (PTC).

Evidence Acquisition: PubMed, Embase, Web of Science, MEDLINE, and Cochrane Library databases were searched for relevant clinical trials. The odds ratio (OR) and 95% confidence interval (CI) showed the effect magnitude of the expression of EGFR, age, gender, tumor size, lymph node metastasis (LNM), extrathyroid extension, and tumor, lymph node, metastasis) stage.

Interchangeability of Electrolyte and Metabolite Testing on Blood Gas and Core Laboratory Analyzers.

Background: Using blood gas (BG) analyzers as backups for core laboratory analyzers has the potential to greatly reduce turnaround times and costs.

Methods: One venous blood gas syringe, one plasma separator tube (PST), and one serum separator tube (SST) were drawn from 42 healthy individuals. All samples were run on the GEM4000 BG analyzer whereas the PST and SST samples were also run on the Roche Modular chemistry analyzer.

Elimination of humic acid in water: comparison of UV/PDS and UV/PMS.

Humic substances are polyelectrolytic macromolecules; their presence in water leads to many environmental problems without effective treatment. In this work, the elimination of humic acid (HA), a typical humic substance, has been examined through ultraviolet (UV) activation systems in the presence of peroxydisulfate (PDS) and peroxymonosulfate (PMS), respectively. The results indicated that 92.

Enhancing CaO fenton-like process by Fe(II)-oxalic acid complexation for organic wastewater treatment.

Hydrogen peroxide (HO) is used widely as Fenton's reagent for organic wastewater treatment. However, the application range of the optimum Fenton reaction is narrow, needing to adjust pH before and after treatment. Besides, the disproportionation of HO and generated iron precipitation also confine the normal operation of Fenton method.

Comparative study of persulfate oxidants promoted photocatalytic fuel cell performance: Simultaneous dye removal and electricity generation.

Introducing peroxymonosulfate (PMS) and peroxydisulfate (PDS) into the photocatalytic fuel cell (PFC) system were investigated by comparing the Reactive Brilliant Blue (KN-R) degradation and synchronous electricity production. The two persulfates (PS) themselves are strong oxidant, and could be activated and as electron sacrificial agent in the PFCs, facilitating the photoelectrocatalysis and expanding redox to the entire cell space. Hence, the two established PFC/PS systems manifested prominent cell performances, enhancing the KN-R decomposition and electric power production relative to the virgin PFC.

Improved degradation of anthraquinone dye by electrochemical activation of PDS.

Electrochemical oxidation (EO) coupled with peroxydisulfate (PDS) activation as a synergistic wastewater treatment process (PDS/EO) was performed to degrade anthraquinone dye-Reactive Brilliant Blue (RBB) in aqueous solution. Introducing PDS into the EO improved the RBB removal than the sole PDS and conventional EO systems. The RBB could activate PDS to a certain degree by itself.

Delayed cord clamping does not affect umbilical cord blood gas analysis.

Background: Although delayed umbilical cord clamping has been shown to have significant benefits for both term and preterm infants, currently, data on its impact on blood gas analysis have been scant and conflicting.

Methods: In a retrospective review, we compared the demographic characteristics and blood gas parameters of 114 delayed cord clamping (DCC-births between 45 and 90 s in length; 109 being for 60 s) versus 407 early cord clamping births (ECC-immediately after delivery) collected over a 1-year period. Intrapartum care and timing of cord clamping for individual cases were performed at the discretion of obstetricians.
