An alumina phase induced composite transition shuttle to stabilize carbon capture cycles.

Limiting global warming to 1.5-2 °C requires a 50-90% reduction in CO emissions in 2050, depending on different scenarios, and carbon capture, utilization, and storage is a promising technology that can help reach this objective. Calcium oxide (CaO) carbon capture is an appealing choice because of its affordability, large potential capacity, and ability to withstand the high temperatures of flue gases.

Ferrioxalate photolysis-assisted green recovery of valuable resources from spent lithium iron phosphate batteries.

Recovering valuable resources from spent cathodes while minimizing secondary waste generation is emerging as an important objective for the future recycling of spent lithium-ion batteries, including lithium iron phosphate (LFP) batteries. This study proposes the use of oxalic acid leaching followed by ferrioxalate photolysis to separate and recover cathode active material elements from spent LFP batteries. The cathode active material can be rapidly dissolved at room temperature using appropriate quantities of oxalic acid and hydrogen peroxide, as determined through thermodynamic calculations.

Facile preparation of poly-(styrene-co-maleic anhydride) encapsulated Iridium(III) complexes as highly efficient electrochemiluminescence indicators for sensitive immunoassay of CYFRA 21-1.

Exploring facile strategy for developing highly efficient emitters using water-insoluble luminophores has become a vital topic in electrochemiluminescence (ECL) immunoassay. In this work, an ECL-active and water-dispersive iridium(III) complex-based polymer dots (IrPdots) was fabricated by encapsulating water-insoluble tris[1-phenylisoquinolinato-C2, N] iridium(III) complexes [Ir(piq)] into poly-(styrene-co-maleic anhydride) (PSMA) matrix by a controllable nanoprecipitation process. The obtained IrPdots generated strong ECL signals in the presence of tri-n-propylamine (TPrA) and were used to label detection antibody (Ab) to act as ECL probes to indicate the signal changes when analyzing target antigen.

Effect of ferrous sulfate modified sludge biochar on the mobility, speciation, fractionation and bioaccumulation of vanadium in contaminated soil from a mining area.

In contaminated soil, pristine biochar has poor applicability for immobilizing vanadium (V), which mainly exists as oxyanions in soil. To elucidate the immobilization potential and biotic/abiotic stabilizing mechanisms of a ferrous sulfate (FS)-modified sludge biochar in a V-contaminated soil from a mining area, we investigated the effects of biochar addition on the soil characteristics, growth of alfalfa, leachability, bioavailability, speciation, and fractionation of V, and changes in the microbial community structure and metabolic response. The results showed that the water extractable, acid-soluble (F1), and pentavalent fractions of V in soil decreased by up to 99 %, 95 %, and 55 %, respectively, whereas the reducible and (F2) oxidizable (F3) fractions increased by up to 45 % and 76 %, respectively.

[Expressions of CXCL8, CXCL10 and Th1 /Th2 cytokines in the serum and cerebrospinal fluid of patients with neurosyphilis].

Objective: To investigate the levels of chemokines 8 and 10 (CXCL8 and CXCL10), Th1 cytokines (IL-2, IL-12 and IFN-γ) and Th2 cytokines (IL-6 and IL-10) in the serum and cerebrospinal fluid of patients with neurosyphilis and elucidate their roles in the immune response and pathogenesis of neurosyphilis.

Methods: Using ELISA, we detected the expressions of CXCL8, CXCL10, IL2, IL-2, IFN-γ, IL-6 and IL-10 in the serum and cerebrospinal fluid of 42 cases of neurosyphilis, 44 cases of syphilis and 40 cases of non-inflammatory diseases of the nervous system (the control group).

Results: The serum levels of CXCL8, CXCL10, IL-2, IL-12, IFN-γ, IL-6 and IL-10 were significantly lower in the neurosyphilis group than in the syphilis and control groups (P < 0.

FGF19 sustains the high proliferative ability of keratinocytes in psoriasis through the regulation of Wnt/GSK-3β/β-catenin signalling via FGFR4.

Accumulating evidence has shown that fibroblast growth factor 19 (FGF19) plays an important role in regulating cell proliferation. Psoriasis is characterized by the hyperproliferation of keratinocytes in skin lesions. However, whether FGF19 regulates the proliferation of keratinocytes in psoriasis remains unknown.

A novel non-enzymatic sensing platform for determination of 5'-guanosine monophosphate in meat.

Graphitic carbon nitride (g-CN) doped carboxylated MWCNTs nanocomposite was synthesized using a simple method. The composite films containing 45 wt%, 50 wt%, 56 wt%, 67 wt% fraction of the carboxylated MWCNTs doped into g-CN were fabricated and characterized. An electrochemical non-enzymatic sensor for determination of 5'-guanosine monophosphate (GMP) based on the nanocomposite was developed.

MicroRNA-194 regulates keratinocyte proliferation and differentiation by targeting Grainyhead-like 2 in psoriasis.

MicroRNAs (miRNAs) are currently emerged as important regulators in psoriasis. Psoriasis is characterized by hyperproliferation and impaired differentiation of keratinocytes in skin lesions. miR-194 is a well-known regulator of cell proliferation and differentiation.
