Abstract

Surface plasmon resonance of metal nanostructures has broad application prospects in the fields of photocatalysis, optical sensing, biomarkers and surface-enhanced Raman scattering. This paper reports a graphene-assisted method for preparing large-scale single crystal Ag(111) nanoparticle arrays based on ion implantation technique. By surface periodic treatment and annealing of the implanted sample, regularly arranged Ag nanoparticles can be prepared on the sample surface. A new application for graphene is proposed, that is, as a perfect barrier layer to prevent metal atoms from evaporating or diffusing. All the Ag NPs show (111) crystal orientation. Besides, the Ag atoms are covered by graphene immediately when they precipitate from the substrate, which can prevent them from being oxidized. On the basis of this structure, as one of the applications of metal SPR, we measured the Raman enhancement effect, and found that the G peak of the Raman spectrum of graphene achieved about 20 times enhancement.

Abstract

Industrial Internet security is a prerequisite and guarantee for the high-quality development of China’s industrial Internet industry; it is also important for enhancing China’s cyber and manufacturing industries. This study aims at the future development of the industrial Internet security industry in China. First, we analyze the development status of the industry in terms of industrial policies, standards system, industrial structure, and industrial scale. Subsequently, we elaborate on the opportunities and trends of the industry and propose the development path for the next-generation industrial Internet security industry in China. To explore a sustainable development path suitable for China’s industrial Internet security industry, top-level design and policy guidance should be enhanced; technological innovation and transformation should be reinforced; advantages of enterprises and organizations should be complemented to construct a healthy development ecosystem; the security and stability of the supply chain should be emphasized; and personnel training and team building should be promoted to support the research collaboration among government, industry, universities, research institutes, and application.

Abstract

We analyzed hemoglobin (Hb) levels and degree of anemia in relation to genotype in patients with hemoglobin H (Hb H) disease, thereby providing a scientific basis for the prevention and treatment of Hb H disease in the Guangxi region of China.Hb analysis was conducted in 615 patients using high performance liquid chromatography. Seven α-thalassemia and 17 β-thalassemia genotypes commonly found in the Chinese population were detected by Gap-polymerase chain reaction and reverse dot hybridization. Multiple ligation-dependent probe amplification and sequencing were used to detect α-globin gene.On analyzing the degree of anemia, we found that the proportion of severe and moderate anemia was the highest among cases with -The clinical manifestations of various types of Hb H disease are heterogeneous; the Hb levels of patients with deletional Hb H are generally higher than those with non-deletional Hb H (
