The trade-off between photobrightening and photobleaching controls the emission stability of colloidal quantum dots. This balance is critical in optical trapping configurations, where irradiances that confine and simultaneously excite the nanocrystals in the focal region cannot be indefinitely lowered. In this work, w…
Many long-wave infrared spectroscopic imaging applications are limited by the portability and cost of detector arrays. We present a characterization of a newly available, low-cost, uncooled vanadium oxide microbolometer array, the Seek Compact, in accordance with common infrared detector specifications: noise-equivale…
Ceruloplasmin (Cp) is one of the most complex multicopper oxidase enzymes and plays an essential role in the metabolism of iron in mammals. Ferrous ion supplied by the ferroportin exporter is converted by Cp to ferric ion that is accepted by plasma metallo-chaperone transferrin. Study of the enzyme at the atomic and m…
The liquid Zr100-xSix (x = 1, 3, and 5) alloys were substantially undercooled by up to 392 K (0.19TL), 423 K (0.21TL), and 451 K (0.23TL), respectively, under the electrostatic levitation condition. The measured dendrite growth velocity of the primary βZr phase increased with the enhancement of liquid undercooling. Al…
We constructed an effective tight-binding model with five Cr $3d$ orbitals for LaOCrAs according to first-principles calculations. Based on this model, we investigated possible superconductivity induced by interactions in doped LaOCrAs using the functional renormalization group (FRG). We find that there are two domes…
We measure linear absorption, circular dichroism, second harmonic, and sum frequency generation in the [Δ-Fe(phen)3](Δ-As2(tartarate)2), [Λ-Fe(phen)3](Λ-As2(tartarate)2) enantiomers of an Fe(II) complex. In the solid state, the chirality of this compound results from the introduction of the (As2(tartarate)2) chiral an…
We treat fundamental resonance effects in hybridized metal–dielectric elements that may find applications in absorption, sensing, and displays. The hybrid structures support guided-mode resonance (GMR) and surface plasmon resonance (SPR) operating independently or in unison. Numerical simulations of periodic resonant…
The realization of both high efficiency and strong bending-durability is a critical issue for future applications of colloidal quantum dot solar cells (CQDSCs) in flexible devices. Herein, we fabricated flexible CQDSCs with a three-dimensional electron transport layer (ETL) composed of a ZnO nanowire (NW) array for ef…
This study aims to find the optimal medium and conditions for polylactic acid (PLA)-degrading enzyme production by Amycolatopsis sp. SCM_MK2-4. Screening of the most effective components in the enzyme production medium by Plackett–Burman design revealed that the silk cocoon and PLA film were the most significant varia…
We have studied the color-center production in sapphire and yttria-stabilized zirconia (YSZ) single crystals by cathodo-luminescence (CL) spectroscopy for electron energies ranging between 400 and 1250 keV in a high-voltage electron microscope. Emission spectra were collected for in-beam conditions near room temperatu…
The purpose of this study was to evaluate a suitable animal model for the in vivo evaluation of patency and vascular tissue regeneration in small intestinal submucosa (SIS) vascular grafts for hemodialysis access. First, a 4-mm U-shaped SIS vascular graft was implanted between the internal carotid artery (CA) and the…
Metallacrown complexes capable of sequestering dianions, as shown in the solid state, also exist in aqueous solution at neutral pH, as demonstrated by calorimetric and mass spectrometric data. The driving forces for the formation of these dimeric complexes in solution strongly depend on the chain length of the guest r…
This paper aims to analyse the effect of coating, fabric layers and structural parameters on the impact resistance behaviour of warp knitted spacer fabrics used for protective clothing. For this purpose, six warp knitted spacer fabrics were produced by varying thickness and mesh structure and were coated with a silico…
Purpose To investigate the feasibility of polymeric micelle of poly(ethyleneglycol) (PEG)‐b‐poly(L‐lysine‐DOTA) (Gd‐micelle) as a contrast agent for magnetic resonance lymphography (MRL). Materials and Methods Twenty‐four female BALB/c mice were randomly divided into four groups of six mice each. Among them, mice of t…
Abstract Materials for CO 2 capture have been extensively exploited for climate governance and gas separation. However, their regeneration is facing the problems of high energy cost and secondary CO 2 contamination. Herein, a reversed photosynthesis‐like process is proposed, in which CO 2 is absorbed in darkness while…
Metasurfaces have shown extraordinary abilities to manipulate the phase and polarization of light and thus hold great promise for applications in photonics and optoelectronics. Here, we propose a unique application of the dielectric metasurface for quantum weak measurements. In our scheme, the dielectric metasurface i…
High Resolution Image Download MS PowerPoint Slide Cyanine dye molecules, used as monomers or in aggregate form, find interesting applications in optoelectronic devices. Among the various aggregate species incorporating organic dyes, centrosymmetric dimers are known as nonluminescent. They can act as exciton quenchers…
Nanoscale heterostructures that interface with multiple distinct materials provide opportunities to engineer functional complexity into single-particle constructs. However, existing synthetic pathways to such hybrid nanoparticles emphasize surface-seeded growth, which limits the scope of accessible systems. Here, we i…
Poly(propyleneimine) dendrimers of fourth generation partially modified with maltose (open shell structure, PPI-m OS) have been proposed as carriers for nucleotide anticancer drugs. The aim of this work was to provide basic insight into interactions between fluorescently labeled PPI-m dendrimer and two distinct leukem…
Vacancies can significantly affect the performance of monolayer MoS2 (mMoS2) nanodevices because defect induced gap states can introduce large Schottky barriers at Pt-mMoS2 interfaces. Effects of adsorbed gases at S-vacancies on the defect induced gap states and Schottky barriers of Pt-mMoS2 interfaces have been studi…
