Summary: Infrared devices are increasingly used in various applications. This paper introduces a novel dispersive spectrometer that has high-throughput and decoupled spectral resolution. The proposed spectrometer utilizes a two-stage Hadamard transform encoding process to increase the signal-to-noise ratio. With a single-pixel detector, the system can be easily implemented in other desired wavelengths. Additionally, a method is developed to remove the need for uniform illumination and improve the ease of device design for in situ measurement.

Summary: Graphene oxide-silver nanoparticle nanohybrids were synthesized by reducing silver nitrate and graphene oxide mixture in water with ascorbic acid as the reducing agent. The concentration of ascorbic acid was varied to study its impact on the efficiency of the hybrids for SERS. Conditioned in ammonia or potassium hydroxide solutions, the composites showed different SERS properties. The sample treated with KOH exhibited the best SERS enhancement, which was correlated with the UV-Vis characteristics and surface structure of the composites.

Summary: In this study, a precursor with ethylene glycol residues was used to synthesize bio-nanocomposites of tannic acid and silica in neutral media without the addition of acid/alkali and organic solvents. The silica was fabricated in the form of optically transparent monoliths with various shapes and 2-4 nm pores. The polyphenol remaining in the pores of the silica matrix served as a reducing agent to synthesize gold and silver nanoparticles in situ. The resulting Au@SiO2 and Ag@SiO2 nanocomposites exhibited localized surface plasmon resonance and high catalytic activity.

Summary: According to the principles of green chemistry, metallic nanoparticles can be synthesized using plant extracts. In this study, deep eutectic solvents (DESs) were used to prepare green tea extracts (GTEs) instead of water, resulting in higher synthesis efficiency and improved properties of silver nanoparticles. Among the DESs, the mixture of glycerol and betaine produced silver nanoparticles with uniform size and crystallinity. Additionally, adding DESs to GTEs enhanced the dispersion of silver nanoparticles.

Summary: The control of surface plasmon using metal micro-nano structures and metal/material composites can generate novel phenomena such as optical nonlinear enhancement, transmission enhancement, orientation effect, high sensitivity to refractive index, negative refraction, and dynamic regulation of low threshold. These phenomena have significant potential in fields such as nano-photonics, super-resolution imaging, energy, sensor detection, and life science. Silver nanoparticles, with their high sensitivity to refractive index change, convenient synthesis, and controllable shape and size, are commonly used in surface plasmon sensors. This review summarizes the basic concept, fabrication, and applications of silver-based surface plasmon sensors.

Summary: This study investigated the effect of temperature and load on the mechanical properties and stress distribution in ECAE processed Al6063. Experimental results showed that billet temperature had a more significant influence on tensile strength and hardness than applied load. The grains in the extrudates became more refined as billet temperature increased. Simulation results indicated that increasing the billet temperature resulted in a more uniform stress distribution with lower magnitude, which enhanced the hardness and tensile strength of the extrudates.

Summary: The environment is crucial for human survival, and it is crucial to protect it from harmful contaminants. While reducing waste has been effective, the increasing global population will result in more waste generation. Unfortunately, this waste negatively impacts the sustainable environment and human health. Conventional remediation methods have limitations in terms of cost, disposal, and the formation of secondary pollutants. To overcome these limitations, nanotechnology offers sustainable solutions.
