Article Synopsis
  • Lithium-sulfur (Li-S) batteries show great potential for energy storage but face challenges due to the shuttling effect of polysulfides, which leads to active material loss.
  • Researchers are exploring the impact of surface engineering in covalent organic polymers (COPs) to enhance the performance of Li-S battery cathodes.
  • Improved pore surface polarity and nano-confinement effects in COPs have resulted in significant performance gains, leading to high Coulombic efficiency and minimal capacity decay over numerous cycles, offering insights for future battery material design.

The practical application of Na-superionic conductor structured materials is hindered by limited energy density and structure damage upon activating the third Na. We propose a bimetal substitution strategy with cheaper Fe and Ni elements for costive vanadium in the polyanion to improve both ionic and electronic conductivities, and a single two-phase reaction during Na intercalation/deintercalation and much reduced Na diffusion barrier are uncovered by ex-situ X-ray diffraction and density functional theory calculations. Thus, the obtained cathode, NaFeVNi(PO), shows excellent electrochemical performances including high specific capacity (102.

The hexagonal rare earth ferrites -RFeO(R = rare earth element) have been recognized as promising candidates for a room-temperature multiferroic system, and the primary issue for these materials is how to get a stable hexagonal structure since the centrosymmetric orthorhombic structure is generally stable for most RFeO at room-temperature, while the hexagonal phase is only stable under some strict conditions. In the present work, -LuInFeO ( = 0-1) thin films were prepared on a Nb-SrTiO (111) single-crystal substrate by a pulsed laser deposition (PLD) process, and the multiferroic characterization was performed at room temperature. With the combined effects of chemical pressure and epitaxial strain, the stable hexagonal structure was achieved in a wide composition range ( = 0.

Background: fusion is a key driver mutation, but it is rare in gastric cancer (GC). Several (hepatocyte growth factor receptor) inhibitors have been approved for the treatment of -positive patients, but the tumor response is heterogeneous. With the development of next-generation sequencing, diverse fusion partner genes have been identified.

Article Synopsis
  • Lithium-sulfur (Li-S) batteries are attracting attention due to their high theoretical capacity and energy density, but polysulfide shuttling negatively impacts their performance.
  • A new two-dimensional covalent organic framework (COF) has been developed to load sulfur efficiently (88.4 wt%), significantly enhancing Li-S battery performance with almost complete capacity release and high Coulombic efficiency (98.0%).
  • Structural analysis suggests that the COF's high conjugation and appropriate spacing contribute to its effectiveness, offering insights for future designs to mitigate polysulfide shuttling in electrochemical energy storage.

The piezoresistive effect has shown a remarkable potential for mechanical sensor applications and been sought for its excellent performance. A great attention was paid to the giant piezoresistive effect and sensitivity delivered by silicon-based nanostructures. However, low thermal stability and complicated fabrication process hinder their practical applications.

Background: This study aims to investigate the effect of lipid metabolism disorder on liver function in patients with malignant tumors after chemotherapy.

Method: A total of 428 patients with malignant tumors with normal liver function in our hospital between May 2013 to June 2018 were divided into an observation group (lipid metabolism disorder, n = 265) and control group (normal lipid metabolism, n = 163). The lipid metabolism levels and liver damage of the two groups were compared before and after chemotherapy.

Background: Investigating the roles of lncRNA prostate cancer-associated transcript 6 (PCAT6) in modulating the growth and aggressiveness of non-small-cell lung carcinoma (NSCLC) cell.

Method: The levels of PCAT6 in NSCLC tissues and cell lines were determined by quantitative real-time PCR assay. MTT as well as colony formation assays were applied to explore the effect of PCAT6 on the growth of NSCLC cell in vitro.

Oral squamous cell carcinoma (OSCC) is a highly invasive lesion that frequently metastasizes to the cervical lymph nodes and is associated with a poor prognosis. Several adhesion factors, including cadherin 6 (CDH6), cadherin 11 (CDH11) and cluster of differentiation 44 (CD44), have been reported to be involved in the invasion and metastasis of multiple types of cancer. Therefore, the aim of the present study was to determine the expression of CDH6, CDH11 and CD44 in tumor tissues from patients with OSCC, and whether this was associated with the metastasis and survival of OSCC.

In the past decades, mesocrystal, a kind of nanocrystals with specific crystallographic orientation, has drawn a lot of attention due to its intriguing functionalities. While the research community keeps searching for new mesocrystal systems, it is equally crucial to develop new approaches to tune the properties of mesocrystals. In this work, a self-organized two-dimensional mesocrystal composed of highly oriented CoFe2O4 (CFO) nano-crystals with assistance of different perovskite matrices is studied as a model system.

Since 1980, the white-browed crake (Porzana cinerea) has been experiencing an expansion from south of the Isthmus of Kra, northward to China. Recently, this species was observed in several locations throughout Southwest China, including Ningming and Baise, Guangxi (2012, 2013), and Xichang, Sichuan (2013). These sightings are the first distribution record of this species in mainland China, suggesting that the white-browed crake is following a natural species dispersal northward into mainland China from Southeast Asia.

In this Letter, we discuss the dramatically enhanced electrostriction and dielectric constant in an all-organic composite consisting of polyvinylidene fluoride trifluoroethylene [P(VDF-TrFE)] copolymer matrix and copper-phthalocyanine (CuPc) particles, which could not be explained by traditional composite theory. Using a Landau-type potential energy combined with energy minimization, we demonstrate that the dramatic property enhancement is due to the exchange coupling between the dielectrically hard P(VDF-TrFE) and dielectrically soft CuPc, which becomes dominant when the heterogeneity size of the composite is comparable to the exchange length. The exchange coupling is a very effective mechanism for the enhancement of functional properties in ferroelectric and dielectric systems, and its variation with various material parameters is demonstrated and discussed.
