HIAF (High Intensity heavy ion Accelerator Facility) is the new generation accelerator under construction in China. The HFRS (FRagment Separator of HIAF) a fragment separator and also transfer-line between Booster Ring Spectrometer ring, which has magnetic rigidity up to 25 Tm. magnet system composed 11 superconducting dipoles 13 sets triplets. Several multipole magnets (an octupole coil, quadrupole sextupole coil) are nested together compact length HFRS-line. All them feature high field...
Abstract Thin film 4H‐silicon carbide (4H‐SiC) is emerging as a contender for realizing large‐scale optical quantum circuits due to its high CMOS technology compatibility and large nonlinearities. Though, challenges remain in producing wafer‐scale 4H‐SiC thin on insulator (4H‐SiCOI) dense integration of photonic circuits, efficient coupling deterministic emitters that are essential scalable photonics. Here, hybrid self‐assembled InGaAs dot (QD)‐based single‐photon sources (SPSs) with chips...

To ensure precise transverse...
Abstract Ultrasmall nanoparticles (NPs) are a promising platform for the diagnosis and therapy of cancer, but particles in sizes as small several nanometers have an ability to translocate across biological barriers, which may bring unpredictable health risks. Therefore, it is essential develop workable cell‐based tools that can deliver ultrasmall NPs tumor safer manner. Here, this work uses macrophages shuttle sub‐5 nm PEGylated gold (Au) tumors actively or passively, while reducing...
Abstract The ultrafast‐laser‐matter interactions enable “top‐down” laser surface structuring, especially for materials difficult to process, with “bottom‐up” self‐organizing features. subwavelength scenarios of laser‐induced structuring are improved in defects and long‐range order by applying positive/negative feedbacks. It is still hardly reported supra‐wavelength more associated complicated thermo/hydro‐dynamics. For the first time knowledge, near‐field‐regulated ultrafast‐laser...

Optical and structural investigations of InAs quantum dots (QDs) covered by InxGa1−xAs (0⩽x⩽0.3) overgrowth layer have been systematically reported. The decrease strain in the growth direction InGaAs instead GaAs is demonstrated transmission electron microscopy experiments. In addition, atomic force measurement shows that surface islands with 3-nm-thick In0.2Ga0.8As becomes flatter. However, nucleate on top during process In0.3Ga0.7As. significant redshift photoluminescence peak energy...
The energy barrier at InAs/GaAs interface due to the built-in strain in self-organized system has been determined experimentally. Such a predicted by previous theories. From deep-level transient spectroscopy (DLTS) measurements, we have obtained electron and hole levels of quantum dots ${E}_{e}^{\mathrm{Q}\stackrel{\ensuremath{\rightarrow}}{D}\mathrm{GaAs}}=0.13\mathrm{eV}$ ${E}_{h}^{\mathrm{Q}\stackrel{\ensuremath{\rightarrow}}{D}\mathrm{GaAs}}=0.09\mathrm{eV}$ relative bulk unstrained GaAs...

The β phase stability in poly(vinylidene fluoride/trifluoroethylene) [P(VDF-TrFE)] thin films was studied below 300 K using X-ray diffraction and polarization-electric-field (P-E) hysteresis loops measurements. On as-grown samples, an irreversible partial order-disorder transformation at Tβ ∼ 250 K, namely, the relaxation temperature, evidenced by appearance of additional X-Ray peak above as well changes on P-E heating after first cooling. This order-disorder-like which is attributed to...

Then, rarefied characteristics under small needle valve opening (less than 1%) focused research, particle position, number density, spatial distribution internal...
Fully rotary drilling is one of many useful technologies used for the exploitation petroleum and geothermal resources, but fully rotating drill-strings are extremely complicated. Therefore, according to Hamilton principle, a non-linear coupled bottom hole assembly (BHA)-bit-formation-wellbore model proposed BHAs with bent-housing positive displacement motor using finite element method investigate dynamic behavior steering ability under drilling. The impact force, acceleration, axial loading,...
Studying the effect of notch on fatigue behavior structural materials is significance for reliability and safety designing engineering components. In this work, we conducted experiments two high-strength materials, i.e. a Ti32.8Zr30.2Ni5.3Cu9Be22.7 metallic glass (MG) 00Ni18Co15Mo8Ti ultra-high strength steel (CM400 UHSS), compared their behavior. Experimental results showed that although both plasticity MG were much lower than those UHSS, endurance limit notched approached to ratio was even...
