The longitudinal momentum (P(axially)) distributions of one- and two-neutron removal fragments ((21,22)O) 23O from the reaction with a C target at 72 A MeV have been measured for first time using new direct time-of-flight method nearly full acceptance breakup fragments. unexpectedly narrow width 21O ( 115 +/- 34 MeV/c in FWHM) is consistent two neutrons occupying 2s(1/2) orbital 23O. This indicates modification core (22O) structure neutron halo-like sd shell nuclei near drip line. also...
Five new alkoxysilanes with different sizes of hydrocarbon substituents were first synthesized and employed as external donors for propylene polymerization a Ziegler–Natta catalyst. The effects these industrial on the microstructure polypropylene studied by SSA 13C NMR. results showed that isotactic sequence length increased size R2 substituent in five donor systems, similar to regularity molecular weight, isotacticity, thermal properties polypropylene. Although produced double cycloalkane...
The volume of ecofriendly salicylate internal donors for propylene polymerization has an important impact on the catalyst active centers and microstructure polypropylene.
We aim to clarify how the chain length influences critical flow rate (qc) for flexible linear chains translocating through cylindrical nanopores in whole range (9.5 > R/r 1.0), where R and r represent size pore size, respectively. By studying translocation behavior of both mono- polydisperse polystyrenes 20 nm nanopores, we have, first time, experimentally revealed that there exist two different regimes, i.e., strong moderate confinement regimes. In regime (R/r λ*), qc is found be...
Cross-linked coordination polymers (<bold>CCP</bold>s) with the formula {[Ru(bda)]<sub>x</sub>L<sub>y</sub>}<sub>n</sub> were developed as heterogeneous catalysts for water oxidation in an organic solvent-free system.
Super-resolution nanoscopy based on wide-field microscopic imaging provided high efficiency but limited resolution. Here, we demonstrate a general strategy to push its resolution down ~50 nm, which is close the range of single molecular localization microscopy, without sacrificing advantage. It done by actively and simultaneously modulating characteristic emission each individual emitter at density. This method principle excited state coherent control single-particle two-photon fluorescence....
The high instantaneous luminosities expected following the upgrade of Large Hadron Collider (LHC) to High-Luminosity LHC (HL-LHC) pose major experimental challenges for CMS experiment.A central component allow efficient operation under these conditions is reconstruction charged particle trajectories and their inclusion in hardwarebased trigger system.There are many involved achieving this: a large input data rate about 20-40 Tb/s; processing new batch every 25 ns, each consisting 15,000...
Differential cross sections for the elastic scattering of halo nucleus 6He on proton target were measured at 82.3 MeV/u. The experimental results are well reproduced by optical model calculations using global potential KD02 with a reduction depth real volume part factor 0.7. A systematic analysis shows that this behavior might be related to weakly bound property unstable nuclei.
Using special anisotropic membranes of bilayered cylindrical channels, we have experimentally clarified the origin inconsistency in transition widths and critical flow rates (qc) reported related ultrafiltration studies flexible linear chains. By studying retention behavior polystyrene chains passing through same membrane but different translocation models, reveal that interaction among fields preconfinement effect are responsible for previously observed inconsistency. In theory, only a...
This work shows how the unique slow diffusion and multi-charge properties of polyelectrolyte ligand dominate catalytic mechanism for water oxidation catalysts.
A novel type of spherical nano Ziegler–Natta catalyst was prepared by loading TiCl4 on nanosized magnesium chloride support for propylene polymerization to form polypropylene (PP) particles. Polyvinylpyrrolidone (PVP), a common macromolecular surfactant, used ensure sphericity and inhibit aggregation the The morphology (60 nm), (80 PP particles (500 nm) were spherical, size distribution is uniform which confirmed scanning electron microscopy (SEM) transmission microscope (TEM), respectively....
In this work, the adsorption kinetics of PBAN/AAO system under flushing condition has been investigated, where PBAN and AAO represent poly(benzyl acrylate) anodic alumina oxide (AAO, average pore radius R0 ≈ 10 nm) nanochannel, respectively. Our specially designed double-pump is proved to eliminate overshoot phenomenon in situ monitor transmembrane pressure (ΔP) as a function time (t) flow rate (Q), which gives effective (R), cross-sectional coverage factor (χ = [1 - (R/R0)2]),...
As a special type of branched polymers, comb-like polymers simultaneously possess the structural characteristics linear backbone profile and crowded sidechain branches/grafts, such uniqueness leads to reduced interchain entanglement, enhanced molecular orientation, unique stimulus-response behavior, which greatly expands potential applications in fields super-soft elastomers, sensors, lubricants, photonic crystals,
Breakup reactions of the double borromean nucleus 8He were measured at 82.3 MeV/u on CH2 and C targets. The coincident detection two decaying neutrons high performance for neutron cross talk rejection are realized in this experiment. relative energy spectrum was reconstructed with good statistics. exhibits a structure resonant peaks, one an excitation about 3.0 other 4.14 MeV, respectively. Substantially larger section first resonance is observed comparison to results reported previously.
