Strong substrate affinity and high catalytic efficiency are persistently pursued to generate high-performance nanozymes. Herein, with unique surface atomic configurations distinct d-orbital coupling features of different metal components, a class highly efficient MnFeCoNiCu transition high-entropy nanozymes (HEzymes) is prepared for the first time. Density functional theory calculations demonstrate that improved between metals increases electron density near Fermi energy level (EF ) shifts...
The AJCC/UICC TNM classification describes anatomic extent of tumor progression and guides treatment decisions. Our comprehensive analysis 8,834 newly diagnosed patients with non-metastatic Epstein-Barr virus related nasopharyngeal carcinoma (NPC) from six Chinese centers indicates certain limitations in the current staging system. 8th edition inadequately differentiates patient outcomes, particularly between T2 T3 categories within N classification. We propose reclassifying cases NPC early...
Abstract Morphology, thermal and rheological properties of polymer‐organoclay composites prepared by melt‐blending polystyrene (PS), poly(methyl methacrylate) (PMMA), PS/PMMA blends with Cloisite® organoclays were examined transmission electron microscopy, small‐angle X‐ray scattering, secondary ion mass spectroscopy, differential scanning calorimetry, techniques. Organoclay particles finely dispersed predominantly delaminated in PMMA‐clay composites, whereas formed micrometer‐sized...
Oxygen evolution reaction (OER) plays a key role in various energy conversion and storage technologies, such as water electrolysis, regenerative fuel cells, rechargeable metal–air batteries. However, the slow kinetics of OER limit performance commercialization devices. Herein, we report on NiFe LDH@Au hybrid nanoarrays Ni foam for much enhanced OER. By hybridization electronegative Au LDH with intrinsic remarkable catalytic activity, this modular electrode could drive an overall...
Highlights•Anatomical factors of RLNs are positively correlated•Advanced RLN ENE is not an independent prognostic factor for NPC•N1/N2 NPC with advanced has a better prognosis than N3 diseaseSummaryAdvanced extranodal extension (ENE) in cervical lymph nodes (CLNs) increases the risk distant metastasis nasopharyngeal carcinoma (NPC). The 9th staging system classifies N1/N2 patients CLN as due to similar outcomes. However, impact retropharyngeal (RLNs) remains unclear. In this study 4,485...
A lamella-forming poly(ethylene oxide)-b-polystyrene (PEO-b-PS) diblock copolymer has been blended with a low molecular weight polystyrene (PS) homopolymer to form miscible polymer blend. The PEO volume fraction is 0.32, and the order−disorder transition temperature (TODT) of this blend 175 °C. Therefore, blocks nanocylinders surrounded by PS matrix below TODT. Since glass 64 °C crystal melting occurs at ∼50 °C, PEO-block crystallization takes place in two-dimensionally confined glassy...
Crystallization temperature (Tc)-dependent crystal orientations within nanoconfined lamellae have been studied in a self-assembled poly(ethylene oxide)-block-polystyrene (PEO-b-PS) diblock copolymer. The copolymer possesses number-average molecular weights of M̄nPEO = 8.7K and M̄nPS 9.2K, it forms microphase-separated lamellar structure the melt. It has found that PEO (the c axis) are determined by only varying Tc.1 Based on real-time simultaneous two-dimensional (2D) small-angle X-ray...
The characteristic properties of a new class long chain branched isotactic polypropylene (LCB-iPP) polymers and the effects its molecular architecture on nature orientation-induced crystallization precursor structures kinetics in flow were investigated. In these polymers, branching (LCB) was introduced via situ polymerization propylene diene monomer using metallocene catalyst technology. LCB-iPP exhibited improved melt strength mechanical properties, such as flexural modulus tensile yield...
Abstract Background The purpose of this study was to verify 10-year results survival and late toxicities assess the ultimate therapeutic ratio intensity-modulated radiotherapy (IMRT) versus two-dimensional (2DRT) in patients with nasopharyngeal carcinoma (NPC). Materials Methods We retrospectively reviewed data from 1,276 nonmetastatic NPC who received IMRT or 2DRT January 2003 December 2006. Results Of patients, 512 were treated 764 2DRT. Median follow-up 115 months. At 10 years, group...
Maleic anhydride (MAH) grafting to different polyolefins with similar degree can have effects on crystallization, crystal structure, and mechanical thermal properties. The leads a smaller size, less ordered lamellar shorter long period for HDPE, LLDPE, PP. makes PP packing the most almost no effect LLDPE. does not that much impact crystallization ability of HDPE/PP blend, but appreciably reduces crystalline PP-g-MAH, due dramatical drop in its molecular weight during process. As result, very...
The morphology of a miscible blend two crystalline polymers (PVF2/PBA) has been investigated by synchrotron small-angle X-ray scattering. Measurements have made as function composition and temperature, probing the morphologies at both spherulitic lamellar levels in semicrystalline/semicrystalline semicrystalline/amorphous states. correlation analysis SAXS profiles permitted determination characteristic morphological parameters level. For state blends containing up to 50 wt % PBA, amorphous...
Abstract In-situ synchrotron wide-angle X-ray diffraction (WAXD) studies and simultaneous measurements of stress strain during uniaxial stretching various vulcanized rubbers were carried out (at room temperature 0°C) to reveal the strain-induced molecular orientation crystallization relationships. Rubbers evaluated included natural rubber (NR), synthetic poly-isoprene (IR), poly-cis-1,4-butadiene (BR) butyl (IIR). Some universal features observed in these systems: (i) At high strains...
Nanoscale tailored polymer crystalline morphology is studied in a polystyrene-b-poly(ethylene oxide) (PS-b-PEO) diblock copolymer with number-average molecular weights for the PS and PEO blocks being 17 000 11 g/mol, respectively. The volume fraction 0.39. After large amplitude planar reciprocating shear, hexagonally perforated layer (HPL) structure obtained. Since glass transition temperature of (72 °C) higher than crystal melting (∼51 °C when crystallization temperature, Tc, lower 40 °C),...
The main aim of this study is to analyze the prognostic differences in nasopharyngeal carcinoma (NPC) patients who are positive and negative for Epstein-Barr virus (EBV).Of 1106 patients, 248 (22.4%) had undetectable pre-treatment plasma EBV DNA levels. total distant metastasis rate EBV-negative group vs. EBV-positive were 3.6% (9/248) 15.0% (128/858) (P < 0.001). estimated 4-year disease-free survival (DFS), overall (OS), metastasis-free (DMFS) locoregional relapse-free (LRRFS) 88.9% 76.9%...
