Surface-enhanced Raman spectroscopy is a powerful and sensitive analytical tool that has found application in chemical and biomolecule analysis and environmental monitoring. Since its discovery in the early 1970s, a variety of materials ranging from noble metals to nanostructured materials have been employed as surface enhanced Raman scattering (SERS) substrates. In recent years, 2D inorganic materials have found wide use in the development of SERS-based chemical sensors owing to their unique th
Functional groups in two-dimensional (2D) Ti<sub>3</sub> C<sub>2</sub> T<sub>x</sub> MXene are an important factor influencing electrochemical performance in many applications involving energy storage, electrochemical sensors, and water purification. However, after dimethyl sulfoxide (DMSO) delamination, the effect of surface functionalities in Ti<sub>3</sub> C<sub>2</sub> T<sub>x</sub> is still unclear and there are no systematic reports on its capacitive behavior. Experiments and theoretical c
The product of the lon gene in Escherichia coli is an ATP-dependent protease, protease La, that also binds strongly to DNA. Addition of double-stranded or single-stranded DNA to the protease in the presence of ATP was found to stimulate the hydrolysis of casein or globin 2- to 7-fold, depending on the DNA concentration. Native DNA from several sources (plasmid pBR322, phage T7, or calf thymus) had similar effects, but after denaturation the DNA was 20-100% more effective than the native form. Al
Abstract Functional materials with attractive electronic and photoelectronic properties show great promise in various fields. In recent decades, tremendous research efforts have been devoted to the design of photoactive and electroactive materials for qualitative and quantitative analysis of environmental pollutants. This review gives a concise overview on the fundamentals and recent research progress of functional material‐based electrochemical and photoelectrochemical technology for environmen
High surface area Pd foams with roughness factors of more than 1000 and a specific surface area of 60 m(2) g(-1) are obtained by electrodeposition. The foams are composed of dendrites with branches on the 10 nm scale. The resulting electrodes show high activity towards the oxidation of C(2) alcohols.
To overcome the drawback of low electrical conductivity within supercapacitor applications, several surfactants are used for nanoscale V2 O5 to enhance the specific surface area. Polyethylene glycol 6000 (PEG-6000), sodium dodecylbenzene sulfonate (SDBS), and Pluronic P-123 (P123) controllers, if used as soft templates, easily form large specific surface area crystals. However, the specific mechanism through which this occurs and the influence of these surfactants is not clear for V2 O5 ⋅H2 O. I
