Researchers mainly explore the mechanism of pseudocapacitance through studying electrode materials with Faraday pseudocapacitive behavior. Here, we found that BiWO, a typical Aurivillius phase material with pseudo-perovskite structure, showed nearly ideal pseudocapacitive behavior. The cyclic voltammetry curve is approximately rectangular in shape, with no redox peaks, which is similar to that of carbon materials.

The characterization results of the phase and morphology of the sample show that it was successfully synthesized and its morphology is composed of micron particles with uneven size and shape. The electrochemical test results of SCs in different electrolytes show that CoF has electrochemical activity only in alkaline electrolytes.

The obtained NiWO /Co-B exhibits crystal-amorphous contact, which makes it have more active sites than other crystalline-crystalline phase boundaries, thereby enhancing electron transport. The NiWO /Co-B electrode with the best mass ratio of crystalline and amorphous exhibits a great specific capacitance and excellent cycle durability.

A mass of heteroatoms was introduced by surface functional group grafting, resulting in enhanced electrochemical performance: the maximum specific capacity of 327.5 F g-1 was obtained at 0.
View Article and Find Full Text PDFLithium-ion capacitors (LICs) are emerging as one of the most advanced energy storage devices by combining the virtues of both supercapacitors (SCs) and lithium-ion batteries (LIBs). However, the kinetic and capacity mismatch between anode and cathode is the main obstacle to wide applications of LICs. Therefore, the effective strategy of constructing a high-performance LIC is to improve the rate and cycle performance of the anode and the specific capacity of the cathode.

Herein, a strategy is presented for the controllable synthesis of cobalt-based phosphides with various morphologies by adjusting the time of the phosphidation process, including 3D hierarchical needle-stacked diabolo-shaped CoP nanorods, 3D hierarchical stick-stacked diabolo-shaped CoP nanorods, and 3D hierarchical heterostructure CoP@CoP nanorods. 3D hierarchical nanostructures and a highly conductive project to accommodate volume changes are rational designs to achieve a robust construction, effective electron-ion transportation, and rapid kinetics characteristics, thus leading to excellent cycling stability and rate performance.

However, due to the inherent vices of poor electronic/ionic conductivities, their practical performance as supercapacitor material is limited. Herein, a cobalt molybdate/cobalt boride (CoMoO/Co-B) composite is constructed with cobalt boride nanoflake-like as a conductive additive in CoMoO nanorods using a facile water bath deposition process and liquid-phase reduction method.

Materials And Methods: A total of 120 cancer patients was randomly divided into two groups, 60 patients took orally morphine sulfate sustained-release tablets in group A, and another 60 patients receiving the combination treatment of intravenous flurbiprofen axetil and opioid drugs in group B. After 7 days, pain relief, quality of life improvement and side effects were evaluated.
Induction of murine double minute 2 (MDM2) expression is thought to be a determinant of resistance to p53 gene therapy for cancer. Previous studies have revealed that ribosomal protein L23 (RPL23) inhibits MDM2-mediated p53 degradation through direct binding to MDM2. In addition, ectopically expressed RPL23 was reported to interact with MDM2 in both the nucleus and cytoplasm, by which RPL23 indirectly inhibited MDM2-p53 binding.

MicroRNAs play key regulatory roles in tumorigenesis and metastasis. In this study, we described that miR-26a, which is usually downregulated in tumor cells, is involved in the acquisition of anoikis-resistance of human esophageal adenocarcinoma (EA) cells.

In the present study, we assessed peritumoral LMVD in lung adenocarcinoma and investigated its correlation with patient prognosis. Using immunohistochemistry (SP method), the D2-40-positive peritumoral LMVD count in lung adenocarcinoma was found to be 11.

Imaging tests revealed that the mass was a solid-cystic tumor with a large size of 143×430×180 mm, penetrating from the pelvic cavity to the subcutaneous tissue. Pathology tests indicated a metastatic mucinous adenocarcinoma which was most likely of gastrointestinal origin.

Nowadays, adenocarcinoma has surpassed squamous cell carcinoma as the most frequent type of lung cancer, but in lung adenocarcinoma, the correlation of TAMs with lymphangiogenesis patients remains unclear. The aim of this study was to examine the relationship between TAMs and lymphangiogenesis and the lung adenocarcinoma patients' prognosis.

Cisplatin (DDP) plus vinorelbine (NVB) constitute the first-line regimen (NP regimen) for NSCLC. This study was to compare the short-term response, long-term outcome, and adverse events between advanced NSCLC patients received NO regimen (LOHP plus NVB) and NP regimen.
