Atomic-resolution image of a graphene sheet synthesized by remote plasma-enhanced atomic layer deposition at low temperatures.

Phosphorus (P) is one of the most limiting nutrients in global agricultural ecosystems, and phosphorus-solubilizing bacteria (PSB) can convert insoluble P into soluble P, thereby improving absorption use soil by plants. Increasing leaching loss due to PSB that could lead water eutrophication a major concern, although no direct experimental evidence available evaluate these effects. In this study, highly efficient strain, Pseudomonas sp. JP233, was isolated from its P-solubilizing agent...

This paper presents a half-select disturb-free 11T static random access memory (SRAM) cell for ultralow-voltage operations. The proposed SRAM is well suited bit-interleaving architecture, which helps to improve the soft-error immunity with error correction coding. read noise margin (RSNM) and write (WM) are significantly improved due its built-in write/read-assist scheme. experimental results in 40-nm standard CMOS technology indicate that at 0.5-V supply voltage, RSNM of <inline-formula...

Saccharum spontaneum L. is a closely related species of sugarcane and has become an important genetic component modern cultivars. Stem development one the factors for affecting yield, while molecular mechanism stem remains poorly understanding in S. spontaneum. Phenylalanine ammonia-lyase (PAL) vital both primary secondary metabolism, contributing significantly to plant growth, stress defense. However, current knowledge about PAL genes still limited. Thus, identification characterization by...

The gas-sensing properties of Pt-decorated carbon nanotubes (CNTs), which provide a foundation for the fabrication sensors, have been evaluated. In this study, we calculated gas adsorption (8,0) single-wall CNTs (Pt-SWCNTs) with SO2, H2S, and CO using GGA/PW91 method based on density functional theory. energies changes in geometric electronic structures after absorption were comprehensively analyzed to estimate responses Pt-SWCNTs. Results indicated that Pt-SWCNTs can respond three gases....

Abstract Catalytically inactive CRISPR‐Cas13 (dCas13)‐based base editors can achieve the conversion of adenine‐to‐inosine (A‐to‐I) or cytidine‐to‐uridine (C‐to‐U) at RNA level, however, large size dCas13 protein limits its in vivo applications. Here, a compact and efficient editor (ceRBE) is reported with high editing efficiency. The larger replaced 199‐amino acid EcCas6e protein, derived from Class 1 CRISPR family involved pre‐crRNA processing, conducted optimization for toxicity ceRBE...

C2H2, C2H4, and C2H6 are important oil-dissolved gases in power transformers. Detection of the composition content transformers is very significant diagnosis assessment state transformer operations. The commonly used oil-gas analysis methods have many disadvantages, so this paper proposes a Ni-doped carbon nanotube (Ni-CNT) gas sensor to effectively detect transformer. gas-sensing properties were studied using test device. Based on density functional theory (DFT) adsorption behaviors three...

ABSTRACT BACKGROUND Insects form both mutualistic and antagonistic relationships with microbes, some microbes have been used as biocontrol agents (BCAs) in pest management. Contextually, BCAs may be inhibited by beneficial insect symbionts, which can become potential barriers to entomopathogen‐dependent biocontrol. Using the symbioses formed one devastating dipteran pest, Delia antiqua , its associated a model system, we sought determine whether interaction between microbial symbionts could...

Fusarium fungi are soil-borne pathogens, and the pathological effects on plant photosystems remain unclear. This study aimed to deeply reveal characterization in apple seedlings infected with solani by investigating performance interaction. Roots were immersed conidial suspension for inoculation. Thereafter, prompt delayed chlorophyll a fluorescence modulated 820 nm reflection simultaneously detected. After 30 days of infection, leaf relative water content dry weight remarkably decreased...

The antibodies of outer membrane proteins (OMPs) bacteria have application value in polyvalent passive vaccines. IgY can be obtained large quantities and economically from egg yolk, the potential to applied aquaculture. OMPs (OmpAII, OmpW, P5, Slp) Aeromonas hydrophila were expressed purified, corresponding prepared. Passive immunization goldfish (Carassius auratus) indicated that four had an effective immune protection rate, could activate innate responses, down-regulated expression...

Vaccination is widely recognized as an effective strategy for preventing various bacterial and viral diseases. In this study, protein, DNA, egg yolk antibody (IgY) vaccines targeting the outer membrane protein VF14355 of Vibrio fluvialis (V. fluvialis) were administered to goldfish (Carassius auratus, C. auratus) subsequently challenged with V. Aeromonas hydrophila (A. hydrophila). The immune efficacy three was evaluated through their activities, protective rates, anti-inflammatory...

Straw return has potential benefits for soil fertility, environmental sustainability, and yield. However, its effects on pathogen carryover disease in subsequent crop cycles remain unclear. Wheat is a crucial food source. This study examined the of straw methods—deep plowing (DP), rotary tillage (RT), deep loosening (DL)—on wheat crown rot. Trials were conducted fields with maize return, rot incidence severity compared after return. The root microbial communities assessed using absolute...

The protection of associated microbiota for their animal hosts against pathogen infection has been studied widely over the last 100 years. However, how those microbes protect host remains unclear. In former studies, body surface one insect, Delia antiqua , protected insect larvae from with entomopathogen Beauveria bassiana . By comparing metabolites produced by that and cannot question is answered. It turns out bacteria produce a metabolite cocktail inhibits colonization B. consequently...
