First principles calculations were performed to investigate the structural, elastic, and electronic properties of $\mathrm{Ir}{\mathrm{N}}_{2}$ for various space groups: cubic $Fm\text{\ensuremath{-}}3m$ $Pa\text{\ensuremath{-}}3$, hexagonal $P{3}_{2}21$, tetragonal $P{4}_{2}∕mnm$, orthorhombic $Pmmn$, $Pnnm$, $Pnn2$, monoclinic $P{2}_{1}∕c$. Our calculation indicates that $P{2}_{1}∕c$ phase with arsenopyrite-type structure is energetically more stable than other phases. It semiconducting...
The lack of highly active and robust catalysts for the oxygen reduction reaction (ORR) at intermediate temperatures significantly hinders commercialization solid oxide fuel cells (SOFCs). Here, we report a novel heterostructured composite nanofiber cathode composed La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) CeO2 nanoparticles, synthesized by using coaxial electrospinning technique, which exhibits remarkably enhanced ORR activity durability as compared to single LSCF powder nanofibers. This achieves...
CD47 on tumor cells protects from phagocytosis, while PD-L1 dampens T cell-mediated killing. However, whether and how coordinate is poorly understood. We reveal that coordinately suppress innate adaptive sensing to evade immune control. Targeted blockade of both with a bispecific anti-PD-L1-SIRPα showed significantly enhanced targeting therapeutic efficacy versus monotherapy. Mechanistically, systemic delivery the dual-targeting heterodimer increased DNA sensing, DC cross-presentation,...
The development of efficient and durable electrocatalysts for oxygen reduction reaction (ORR) is essential the application intermediate-temperature solid oxide fuel cells (IT-SOFCs). Here, we report our findings in notably improving ORR dynamics stability A-site-deficient (La0.6Sr0.4)0.95Co0.2Fe0.8O3−δ (LSCF) cathode using PrO2−δ/Pr0.8Ce0.2O2−δ nanoparticles. LSCF + PrO2−δ shows an area-specific resistance ∼0.241 Ω cm2 at 600 °C, which about 67% lower than that pristine (∼0.738 cm2)....
Spinel ferrite, MFe2O4 (M = Co, Ni), ribbons with nanoporous structure were prepared by electrospinning combined sol−gel technology. The formed through the agglomeration of magnetic nanoparticles PVP as directing template. length polycrystalline can reach millimeters, and width be tuned from several micrometers to hundred nanometers changing concentration precursor. was during decomposition inorganic salts. exhibited weak saturation magnetizations low coercivities at room temperature, but...
Single-component electrolyte-free fuel cells possess a similar function to the traditional with complex three-component structure. However, how enhance their electrical properties for practical industrial applications remains timely and important issue. Here, we report manipulation of concentration ratios ionic electronic conductors in an Ce0.8Sm0.2O2-δ–Li0.15Ni0.45Zn0.4 by adjusting relative weight between its two inside compositions. Our systematic investigations reveal that cell 30%...
The broad and large-scale application of solid oxide fuel cells (SOFCs) technology hinges significantly on the development highly active robust electrode materials. Here, Ni-free anode materials decorated with metal nanoparticles are synthesized by in situ reduction Fe-doping Sr2CoMo1–xFexO6−δ (x = 0, 0.05, 0.1) double perovskite oxides under a reducing condition at 850 °C. exsolved from Sr2CoMo0.95Fe0.05O6−δ (SCMF0.05) lattice Co–Fe alloys rich multiple-twinned defects, enhancing catalytic...
Kartagener syndrome (KS), a subtype of primary ciliary dyskinesia (PCD), is rare genetic disorder characterized by situs inversus , chronic sinusitis, bronchiectasis, recurrent respiratory infections, and impaired function. It diagnosed through physical examination, imaging techniques such as computed tomography (CT), nasal nitric oxide measurement, testing, pulmonary function tests. We present case study 15-year-and-11-month-old male patient with KS complicated secretory otitis media,...
Background The prevalence of major depressive disorder (MDD) is higher in those with low levels educational attainment, the unemployed and social status. However extent to which these factors cause MDD unclear. Most available data comes from studies developed countries, findings may not extrapolate developing countries. Examining relationship between socio economic status China likely add debate because radical changes occurring over last 30 years. Principal We report results 3,639 Chinese...
Oxygen vacancy (VO) formation energy and its migration barrier are two determining factors for the effectiveness of solid electrolytes (SEs) in oxide fuel cells (SOFCs). In this work, a series aliovalent rare-earth-doped ceria (Ln xCe1- xO2-δ, Ln = lanthanides) compounds serving as SEs comprehensively comparatively calculated, through which determinant oxygen formations their activity figured out at an atomistic level via first-principles calculations with consideration electronic...
