Highly efficient Ni/Ac-AlO catalysts in the dry reforming of methane: influence of acetic acid treatment and Ni loading.

The presence of abundant hydroxyl groups on the surface of AlO can promote the dispersion of Ni species but produce an inactive NiAlO phase at high temperatures. Moreover, the catalysts prepared by the conventional incipient wetness impregnation method lack the sites for the activation of CO, which leads to coke deposition and thus affects the catalyst activity. The above restricts the utilization of Ni in conventional Ni/AlO catalysts.

Process Condition Optimization and Structural Feature Analysis of Humic Acid Extraction from Weathered Lignite.

In this study, response surface methodology (RSM) was adopted to investigate the optimization of process conditions for extracting humic acid (HA) from coal, aiming to enhance the yield of humic acid. Additionally, UV-vis spectroscopy, FTIR, XRD, TG-DTG, CP/MASCNMR, XPS, and molecular fluorescence were utilized to examine the properties of HAs. The extraction time significantly influenced the yield from Lishi weathered lignite, while the liquid-solid ratio had a significant impact on the yield from Wuhai weathered lignite.

A novel photoelectrochemical immunosensor by integration of nanobody and TiO₂ nanotubes for sensitive detection of serum cystatin C.

Cystatin C (CysC) is a sensitive marker for the estimation of the glomerular filtration rate and the clinical diagnosis of different diseases. In this paper, CysC-specific nanobodies (Nbs) were isolated from a phage display nanobody library. A simple and sensitive photoelectrochemical immunosensor based on TiO2 nanotube arrays (TNAs) was proposed for the sensitive detection of CysC.

Nucleosome alterations caused by mutations at modifiable histone residues in Saccharomyces cerevisiae.

Nucleosome organization exhibits dynamic properties depending on the cell state and environment. Histone proteins, fundamental components of nucleosomes, are subject to chemical modifications on particular residues. We examined the effect of substituting modifiable residues of four core histones with the non-modifiable residue alanine on nucleosome dynamics.

Characterization and applications of Nanobodies against human procalcitonin selected from a novel naïve Nanobody phage display library.

Background: Nanobodies (Nbs) are single-domain antigen-binding fragments derived from the camelids heavy-chain only antibodies (HCAbs). Their unique advantageous properties make Nbs highly attractive in various applications. The general approach to obtain Nbs is to isolate them from immune libraries by phage display technology.

Bactrian camel nanobody-based immunoassay for specific and sensitive detection of Cry1Fa toxin.

The variable domain of the heavy-chain-only antibody (VHH) or nanobody (Nb), derived from camelids, begins to play an important role on the detection of protein markers. In this study, we constructed a phage-displayed library of VHHs against Cry1Fa by immunizing a healthy Bactrian camel with Cry1Fa toxin. After a series of bio-panning and screening by phage display technology, three anti-Cry1Fa nanobodies (Nbs) with great difference in complementarity determining region 3 (CDR3) were obtained and they were highly specific to Cry1Fa as well as showed full of activity when exposed to 70 °C for 3 h.

Elevated CO2 alters the feeding behaviour of the pea aphid by modifying the physical and chemical resistance of Medicago truncatula.

Elevated CO(2) compromises the resistance of leguminous plants against chewing insects, but little is known about whether elevated CO(2) modifies the resistance against phloem-sucking insects or whether it has contrasting effects on the resistance of legumes that differ in biological nitrogen fixation. We tested the hypothesis that the physical and chemical resistance against aphids would be increased in Jemalong (a wild type of Medicago truncatula) but would be decreased in dnf1 (a mutant without biological nitrogen fixation) by elevated CO(2). The non-glandular and glandular trichome density of Jemalong plants increased under elevated CO(2), resulting in prolonged aphid probing.

Antennal morphology and sensilla ultrastructure of three Tomicus species (Coleoptera: Curculionidae, Scolytinae).

The antennal morphology and sensilla ultrastructure of Tomicus yunnanensis, T. minor, and T. brevipilosus were studied by scanning electron microscopy and transmission electron microscopy.
