Research on the Development Path of Zigong Salt Culture and Creative Industry in the Era of Digital New Media

Salt culture is the main component of traditional culture in Zigong,Sichuan.With centuries of history, it has accumulated rich cultural connotations. At present, Zigong salt culture, as a precious traditional cultural wealth, has taken cultural and creative industries as a new carrier of communication in the rapid development of digital new media technology, giving full play to the resource advantages of its traditional culture. This article focuses on the study of the development path of Zigong salt cultural and creative industry in the new digital media era. Combining digital new media technology with cultural and creative industries, Zigong salt culture actively uses virtual technology to realize the innovative development of cultural and creative industries, promote the cultivation of cultural and creative brands based on digital new media technology. This article aims to give relevant strategies with reference value, so as to make corresponding contributions to the development path of Zigong salt culture in the future

Study on the bolt-mesh-anchor support technology for mining roadway in complex coal seam

The stability of mining roadway is affected significantly by the condition of the surrounding rock and stress regime, which is the key factor for determining the roadway support program. Located in syncline axis, the No.15 seam is a steep seam at - 230 m level in Changgouyu coal mine, the original flexible shield cannot meet the safety and production requirement. The No.15 seam is classified as unstable and relatively complex according to the analytic hierarchy process (AHP). The distribution characteristics of stress in the seam around the synclinal axis before and after mining are analysed by use of FLAC2D. According to the complexity of the coal seam and the stress distribution characteristics, the supporting parameters using bolt-mesh-anchor were selected and implemented successfully in an underground roadway, which can be referred to as in the design of roadway support in similar complicated coal seams

Designing a Reactor Chamber for Hot Electron Chemistry on Bimetallic Plasmonic Nanoparticles

Catalysis provides pathways for efficient and selective chemical reactions by lowering the energy barriers for desired products. Gold nanoparticles (AuNPs) show excellent promise as plasmonic catalysts. Plasmonic materials have localized surface plasmon resonances, oscillations of the electron bath at the surface of a nanoparticle, that generate energetically intense electric fields which rapidly decay into energetically excited electrons. The excited electrons have the potential to destabilize atoms strongly bound to the catalysts through occupation of antibonding orbitals. Tuning the antibonding orbitals to make them accessible for occupancy by electrons is achieved by coating the AuNP in a thin layer of another transition metal, such as ruthenium, silver, or platinum, creating a bimetallic nanoparticle. We will initially study carbon monoxide (CO) oxidation in the presence of ruthenium-gold bimetallic nanoparticles (RuAuNPs), as CO oxidation is a well modeled system. Carbon and oxygen atoms are strongly bound in CO molecules and the bond between oxygen and ruthenium is typically strong, inhibiting reaction rates. Excited electrons from the AuNPs can transfer to the oxygen-ruthenium antibonding orbital and weaken the bond and making the atomic oxygen more reactive. We will observe the CO oxidation reaction and, subsequently, the chemical properties of the synthesized RuAuNP catalysts, in a modified single-tangent photoreactor chamber that we designed during the SURF program. A light source will be used to excite the RuAuNPs and the photocatalytic activity of the bimetallic catalysts will be assessed via mass spectrometry

The variability of shelf-margin morphology and controlling factors : a case study of a northwestern South China Sea shelf-margin

A shelf-margin from Qiongdongnan Basin, northwestern South China Sea was studied. Geometric parameters (clinoform heights, lengths, forest inclinations) and accretion rates (progradation rates and aggradation rates) were measured, shelf-edge trajectories were depicted, and ancient sediment flux across the shelf-edge area were calculated using Petter et al 2013 methodology. The shelf-margin was divided into three depositional packages in terms of different shelf-margin growth patterns. The lower most depositional package (10.5 - 5.5 My) exhibits strong progradation tendency but minimum to even negative aggradation, which is likely due to the anomalous post-rift subsidence that occurred along the northern Qiongdongnan Basin during Middle Miocene to Late Miocene. In contrast, the upper most package (1.9 My - present) mainly grew vertically and managed to maintain a relatively high-rising trajectory because the shelf had become very wide (200 – 280 Km, Xie et al 2008) since Late Miocene and the sediment supply was highly insufficient and fine-grained. It is also likely that this very high supply rate of mud results at least partly from along-strike mud delivery, possibly as littoral fluid mud plumes, from the mouth of the Red River Delta. The middle package exhibits somewhat a mixed progradational and aggradational character with moderate clinoform dimensions and moderate accretion rates, which is likely to be a result of a reasonable balance between supply and accommodation.Energy and Earth Resource
