Abstract Absorbers with lightweight, low filler loading and broad absorption band are highly desirable for electromagnetic wave field. Here, hollow Co 1– x S microspheres constructed by nanosheets fabricated via a facile synthetic method based on hydrothermal route. As an efficient absorber, the spheres demonstrate excellent microwave performance. With weight content of only 3 wt%, maximum reflection loss (RL) can reach as strong −46.1 dB at 13.92 GHz its qualified frequency bandwidth (with...
The three-dimensional (3D) MoS2 hierarchical nanospheres which assembled spontaneously by two-dimensional (2D) lamina have been successfully designed and fabricated in large scale via a simple hydrothermal process. Subsequently, the electromagnetic wave absorption properties of compounded with polyvinylidene fluoride (PVDF) were investigated broad frequency range 2–40 GHz. results indicated that MoS2/PVDF nanocomposites possess adjustable enhanced performance. Furthermore, MA performance can...
Core–shell structural NiS<sub>2</sub>@MoS<sub>2</sub>nanospheres have been successfully fabricated and they possess enhanced microwave absorption properties as compared to single NiS<sub>2</sub>nanospheres or MoS<sub>2</sub>nanoplates due this core–shell structure.
RNA-targeting small molecules (rSMs) have become an attractive modality to tackle traditionally undruggable proteins and expand the druggable space. Among many innovative concepts, chimeras (RNATACs) represent a new class of multispecific, induced proximity that act by chemically bringing RNA targets into with endogenous effector, such as ribonuclease (RNase). Depending on RNATACs can alter stability, localization, translation, or splicing target RNA. Although still in its infancy, this has...
Reduced graphene oxide (rGO)@MoS2 composites with a loose structure were prepared and added to poly(vinylidene fluoride) (PVDF) form that showed superior microwave absorption excellent electromagnetic interference shielding performances. The maximum reflection loss of the rGO@MoS2 /PVDF composites, low filling rate (only 5.0 wt %), can reach -43.1 dB at 14.48 GHz, frequency bandwidth below -10 is 3.6-17.8 GHz (in range 2-18 GHz) thickness 1-5 mm. Furthermore, higher (25 %) also exhibit...
The rGO/BT/PVDF core/shell architectures synthesized with a sample method show superior microwave absorption properties.
Core–shell structural MnFe<sub>2</sub>O<sub>4</sub>@SiO<sub>2</sub> nanocomposites have been fabricated. Our findings indicate that the ternary MnFe<sub>2</sub>O<sub>4</sub>@SiO<sub>2</sub>/PANI/PVDF composites filled with 20 wt% and PANI show most excellent wave absorption performance.
Abstract Binding of precursor tRNAs (ptRNAs) by bacterial ribonuclease P (RNase P) involves an encounter complex (ES) that isomerizes to a catalytic conformation (ES*). However, the structures intermediates and conformational changes occur during binding are poorly understood. Here, we show pairing between 5′ leader 3′RCCA extending acceptor stem ptRNA inhibits ES* formation. Cryo-electron microscopy single particle analysis reveals dynamic enzyme becomes ordered upon formation in which...
Hylurgus ligniperda is an imported quarantine plant pest in China. Its identification usually based on morphological characteristics; therefore, species needs high professional requirements of staff and professionals with experience accumulated through long-term training. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) a rapid technology, which protein profiles species. It has been widely used for the pathogenic microorganisms. Many studies have...
Bacterial ribonuclease P (RNase P) is a tRNA processing endonuclease that occurs primarily as ribonucleoprotein with catalytic RNA subunit (P RNA). As one of the first ribozymes discovered, well-studied model system for understanding catalysis and substrate recognition. Extensive structural biochemical studies have revealed structure RNase bound to precursor (ptRNA) product tRNA. These also helped define active site residues propose molecular interactions are involved in binding catalysis....
