Polyvinyl pyrrolidone (PVP) with different molecular weights was used as capping agent to synthesize silver nanowires through a polyol process. The results indicated that the yields and aspect ratios of were controlled by chain length PVP increased increasing weight (MW) PVP. When long-chain PVP-K90 (MW = 800,000) used, product uniform in size dominated high ratios. growth mechanism studied. It is proposed chemical adsorption Ag + on chains at initial stage promotes nanowires.
This paper describes a poly(vinylpyrollidone)-directed polyol synthesis method for the fabrication of silver (Ag) nanostructures with well-controlled shapes (such as nanorods and nanocubes) by adjusting synthesizing parameters. The structure characterizations suggest that Ag grow from five-fold twinned decahedral crystal nuclei. nature {1 1 1} planes highly selective poly(vinylpyrollidone) adsorption on {100} nuclei are favourable formation nanowires. single crystalline nanocubes obtained at...
In the Chaixi region of Qaidam Basin’s Qigequan tectonic zone, compact sandstones are characterized by their low porosity and permeability, featuring intricate pore-throat formations, varied lithologies, assorted clay minerals, pronounced unevenness among reservoirs. There’s a weak link between reservoir metrics logging reactions, making it challenging to assess these parameters. The microscopic pore structure can be illustrated through both nuclear magnetic resonance relaxation time...
Abstract The synthesis and growth mechanism of well‐defined nanostructures are still challenging. In this study, gold microplates with starlike, shieldlike, other polygonal shapes successfully achieved in high yields on the basis polyol process. Structural studies demonstrate that these newly shaped Au plates single‐crystalline, several micrometers lateral size, tens nanometers thickness. It is believed introduction temperature variation early stage crystal important for products. discovered...
A novel and simple chemical method was developed to fastly synthesize Au nanoplates with size of micrometers tens nanometers in thickness.

The sound velocity in a medium is closely related to its material properties, including composition, structure, density, pressure, and temperature. Various methods have been developed determine the through materials. Among them, strategy based on ultrasound resonance frequency has most widely used due simplicity. However, it requires transducer with wide bandwidth cover enough frequencies perform consequent calculations. In this paper, we develop method for measuring velocity, using...
