A series of shape amphiphiles based on functionalized polyhedral oligomeric silsesquioxane (POSS) head tethered with two polymeric tails symmetric or asymmetric compositions was designed and synthesized using sequential "grafting-from" "click" surface functionalization. The monofunctionalization octavinylPOSS performed thiol-ene chemistry to afford a dihydroxyl-functionalized POSS that further derived into precisely defined homo- heterobifunctional macroinitiators. Polymer tails, such as...
Integrating semiconductor photocatalysts with outstanding visible light absorption and fast surface/interface charge transfer kinetics is still an enormous challenge for efficient CO2 photoreduction. In this work, the Au nanoparticles have been coupled ultrathin BiOBr nanosheets, formed heterostructure (Au/BiOBr) possesses a localized surface plasmon resonance (LSPR) enhances ability, as well forms transport channel on interface between BiOBr. Thus, photocatalyst exhibits higher...
Endowing a semiconductor with tunable edge active sites will effectively enhance catalytic performance. Herein, an edge-site-rich ordered macroporous BiOCl (BiOCl-P) abundant dangling bonds is constructed via the colloidal crystal template method. The structure provides adsorption for CO2 molecules, as well forms numerous localized electron enrichment areas, accelerating charge transfer. DFT calculations reveal that bonds-rich configuration can reduce activation energy barrier, boost CO...
In traditional compressed sensing MRI methods, single sparsifying transform limits the reconstruction quality because it cannot sparsely represent all types of image features. Based on principle basis pursuit, a method that combines transforms to improve sparsity images is proposed. Simulation results demonstrate proposed can well recover different features and be easily associated with total variation.
The photocatalytic CO2 conversion efficiency of semiconductor materials still suffers from the faint surface adsorption capacity and sluggish reaction kinetics. Among modification strategies, defect engineering is considered as a promising approach for ameliorating catalytic performance bulk materials. Herein, an ionic liquid 1-dodecyl-3-methylimidazolium chloride-assisted alkali solvothermal method was employed synthesis ultrathin Bi24O31Cl10 nanosheets with abundant oxygen vacancies...
The self-assembly behaviors of fluorinated polyhedral oligomeric silsesquioxane (FPOSS)-based giant surfactants, consisting an FPOSS cage and a polystyrene-block-poly(ethylene oxide) (PS-b-PEO) diblock copolymer tail, are studied in the bulk. tethering point on PS-b-PEO chain can be controlled precisely either at end PS block or junction between PEO blocks, resulting topological isomer pairs with almost identical chemical compositions but different architectures. Phase separation head tail...
Convenient synthesis of fluorinated molecular nanoparticles constitutes a major challenge in the preparation fluoro shape amphiphiles. To facilitate modular and efficient synthesis, "clickable" polyhedral oligomeric silsesquioxane functionalized with seven 1H,1H,2H,2H-heptadecafluorodecyl side chains one alkyne group on its periphery (FPOSS-alkyne) was designed synthesized. It then used to prepare series FPOSS-containing polymers various architectures via "click" chemistry. FPOSS tethered...
We describe highly unconventional situations in which the polymer chain ends remain trapped and are located middle of lamellar crystal core as defects. Such structures observed giant molecular shape amphiphiles constructed by a polyhedral silsesquioxane (POSS) nanoparticle tethered with poly(ethylene oxide) (PEO) tail. The cross-sectional area POSS on PEO surfaces imposes that crystalline, chain-folded tails generate surface is at least comparable to requirements. Metastable 1.5, 2, 2.5 stem...
Chronic obstructive pulmonary disease (COPD), a preventable lung disease, has the highest prevalence in elderly and deserves special consideration regarding earlier warnings this fragile population. The impact of age on COPD is well known, but risk aging process lungs remains unclear. Therefore, it necessary to understand lungs, providing an early decision for adults.COPD evaluated adults make from perspective radiomics features. First, subjects are divided into four groups according stages....
<abstract> <p>Computed tomography (CT) has been the most effective modality for characterizing and quantifying chronic obstructive pulmonary disease (COPD). Radiomics features extracted from region of interest in chest CT images have widely used lung diseases, but they not yet extensively investigated COPD. Therefore, it is necessary to understand COPD radiomics apply them diagnostic applications, such as stage classification. Lung are classifying this paper. First, 19 selected...
Background The anatomically constrained registration network (AC-RegNet), which yields plausible results, has emerged as the state-of-the-art architecture for chest X-ray (CXR) images. Nevertheless, accurate lung field results may be more favored and exciting than of entire CXR images hold promise dynamic analysis in clinical practice. Objective Based on above, a model based AC-RegNet static is urgently developed to register these fields quantitative analysis. Methods This paper proposes...
