Slow reaction kinetics during redox reactions limits the utilization of the high theoretical energy density of lithium-oxygen batteries (LOBs). Vacancy engineering, a potential strategy for modulating active sites, is critical in the development of high performance catalysts. This study investigates cobalt vacancies in Mo-CoSe nanoparticles created by selenization of phosphomolybdic acid (POM) embedded into zeolitic imidazolate framework-67 (ZIF-67).

The construction of a high-performance photocathode is essential for improving Li-O battery performance and solar energy utilization. However, the single pore and few active reaction sites of the photocathode result in insufficient discharge capacity and unsatisfactory cycling durability. Herein, we designed and fabricated a self-standing 3D-printed multi-pore graphene-based photocathode direct ink writing (DIW) featuring non-competitive three-phase transmission channels to promote the transport of Li, e, and O.

Introduction: COVID-19 has been associated with several adverse pregnancy outcomes, including perinatal loss. Differential effects of COVID-19 in a twin pregnancy may provide unique insights into virus-placental interactions. We present a case of perinatal loss of a female fetus with survival of the male co-twin in a pregnancy complicated by COVID-19 and premature delivery.

Parathyroid cyst is a rare entity that can closely mimic thyroid and brachial cleft cysts, particularly when located within the thyroid gland. Most commonly, the cysts are non-functional but can produce compressive symptoms. The cyst contains watery content with elevated PTH levels, specifying parathyroid origin.

Dual-electrolyte Li-air batteries (LABs) have the advantages of high specific energy density and low overpotential, but the mass transfer mechanism is still unclear. Mass transfer is essential to battery performance. To improve the mass transfer capability of the positive electrode, this research studied the effect of boron (B)-doped carbon nanotubes (BCNTs) with different amounts of defects as positive electrodes.

Models that accurately estimate maximum crop biomass to obtain a reliable forecast of yield are useful in crop improvement programs and aiding establishment of government policies, including those addressing issues of food security. Here, we present a new sigmoidal growth model (NSG) and compare its performance with the beta sigmoidal growth model (BSG) for capturing the growth trajectories of eight crop species. Results indicated that both the NSG and the BSG fitted all the growth datasets well (R > 0.

Article Synopsis
  • Semiconductor detectors like Si-PIN and CdTe are important for energy dispersive X-ray fluorescence measurements and were compared in terms of material properties, efficiency, and energy resolution.
  • The study examined how factors like detector thickness, X-ray energy, and circuit shaping time affect performance, including issues like incomplete hole collection causing energy spectrum differences.
  • Results showed that while both detectors are efficient below 15 keV, CdTe performs better above that energy; Si-PIN offers superior energy resolution, but implementing a DMCA reduces hole tailing effects in CdTe, enhancing its performance.

Background: Progenipoietin-4 (ProGP-4) is an E. coli derived chimeric growth factor that activates the human Flt3 and G-CSF receptors. ProGP-4 possesses cross-species activity and treatment of mice with ProGP-4 results in increases in the number of WBC and Class II+/CD11c+ cells in both spleen and peripheral blood.
