Multiple plasmon couplings in 3D hybrid Au-nanoparticles-decorated Ag nanocone arrays boosting highly sensitive surface enhanced Raman scattering

Zewen Zuo (✉), Lianye Sun, Yongbin Guo, Lujun Zhang, Junhu Li, Kuanguo Li, and Guanglei Cui

Three-dimensional hybrid plasmon systems composed of ordered Ag nanocone arrays decorated with high-density Au nanoparticles are constructed by a template-assisted physical vapor deposition approach. Such structures allow for multiple plasmon couplings among various resonance modes, producing intense and high-density hot spots which boost a high-performance surface enhanced Raman scattering (SERS) detection with high sensitivity, high reproducibility, and quantitative analysis ability.

Zitao Hu and Yin Ding (✉)

Our reported treatment can selectively and greatly enhance intracellular O₂ and reactive oxygen species (ROS) levels in tumor region, which depends on two-step catalytic properties of nanoceria (Ce⁴⁺/Ce³⁺ = 3.46, neutral surface charge, mostly localize into the cytoplasm, pH 7.4–6.5, catalase-like catalytic agents convert to Ce⁴⁺/Ce³⁺ = 0.58, negative surface charge, mostly localize into the lysosomes, pH 5–4, oxidase-like catalytic agents, triggered by near infrared (NIR) laser irradiation).

Advanced photocatalysts based on metal nanoparticle/metalorganic framework composites

Jun Guo^1,2, Yue Wan¹, Yanfei Zhu^2,3, Meiting Zhao¹ (✉), and Zhiyong Tang^2,3 (✉)

Two birds with one stone: Metal nanoparticle (MNP)/metalorganic framework (MOF) composites exert superior performance in photocatalysis than their individual counterparts. This review introduced the synthesis strategies of MNP@MOF composites and highlighted their recent progress in photocatalytic hydrogenation, carbon dioxide reduction, organic transformations and degradation of pollutants.

Induced structural modifications in ZnS nanowires via physical state of catalyst: Highlights of 15R crystal phase

Sumit Kumar¹ (✉), Frédéric Fossard², Gaëlle Amiri¹, Jean-Michel Chauveau¹, and Vincent Sallet¹ (✉)

ZnS nanowires (NWs) have been grown by two different approaches based on the physical state of the catalyst, specifically called vapor–liquid–solid (VLS) and vapor–solid–solid (VSS). Both approaches present unique structural properties, and remarkably, the crystallization of a 15R structure is highlighted in NWs grown by the VLS process.

Flexible multi-level quasi-volatile memory based on organic vertical transistor

Huihuang Yang^{1,^2,§}, Qian Yang^1,2,3,§, Lihua He¹, Xiaomin Wu¹, Changsong Gao¹, Xianghong Zhang¹, Liuting Shan¹, Huipeng Chen^1,2 (✉), and Tailiang Guo^1,2

This work proposed a new type of multi-level quasi-volatile memory based on organic vertical transistor. Contributing to vertical structure and appropriate doping ratio of blend film, the different memory current levels with highly fault-tolerant could be achieved along with these features of high writing speed and decent retention characteristics, which fill the gap between volatile and non-volatile memories.
