The remarkable electrocatalytic properties and small size of carbon nanotubes make them ideal for achieving direct electron transfer to proteins, important in understanding their redox the development biosensors. Here, we report shortened SWNTs can be aligned normal an electrode by self-assembly act as molecular wires allow electrical communication between underlying proteins covalently attached ends SWNTs, this case, microperoxidase MP-11. efficiency through is demonstrated electrodes...
Data analysis is central to understanding phenomena in host-guest chemistry. We describe here recent developments this field starting with the revelation that popular Job plot method inappropriate for most problems chemistry and focus should instead be on systematically fitting data testing all reasonable binding models. then discuss approaches estimating uncertainties studies using case simulations highlight key issues. Related need ready access transparency methodology or software used, we...
The electrochemical nitrogen reduction reaction (NRR) provides a sustainable alternative to the Haber–Bosch process for ammonia (NH3) production. Transition metal catalysts have poor NRR performance due highly competitive hydrogen evolution and scaling relation between inert dinitrogen (N2) other intermediates. Owing enhanced active sites anomalous quantum size effect, single-atom (SACs) been proven be effective in overcoming these limitations. Inspired by our understanding of metal–sulfur...
This IUPAC study aims at formulating recommendations concerning the metrological traceability of a measurement result in chemistry. It is intended to provide chemical community with consistent view creation, meaning, and role its underpinning concepts. No distinction made between results obtained “high metrology” “field”. A description given calibration hierarchies needed different circumstances arrive along chain. Flow charts generic are presented as well variety examples. The...
Abstract This project was aimed to identify the quenching chemistry of biologically important reactive oxygen and nitrogen species (ROS/RNS, including radicals), show antioxidant action against through H‐atom electron transfer reactions, evaluate ROS/RNS scavenging activity antioxidants with existing analytical methods while emphasizing underlying chemical principles advantages/disadvantages these methods. In this report, we focused on applications impact assays potentiating future research...
Abstract Recommendations are given concerning the terminology of methods used in electroanalytical chemistry. Fundamental terms electrochemistry reproduced from previous PAC Recommendations, and new updated material is added for chemistry, classification electrode systems, techniques.
Abstract Three double‐armed diazacrown ethers with two thiophene side groups, 7,16‐dithenyl‐1,4,10,13‐tetraoxa‐7,16‐diazacyclooctadecane (DTDC), 7,16‐dithenoyl‐1,4,10,13‐tetraoxa‐7,16‐diazacyclooctadecane (DTODC), and 7,16‐di‐(2‐thiopheneacetyl)‐1,4,10,13‐tetraoxa‐7,16‐diazacyclooctadecane (DTAODC), have been synthesized used as novel neutral lead(II) ionophores in ion selective electrode applications. The relationship between the molecular structure of these electrochemical properties...
An electrochemical metal ion sensor has been developed with a detection limit of less than 0.2 ppt by the covalent attachment tripeptide Gly-Gly-His as recognition element to 3-mercaptopropionic acid modified gold electrode.
The modification of electrodes with the tripeptide Gly-Gly-His for detection copper in water samples is described detail. modified electrode was prepared by first self-assembling 3-mercaptopropionic acid (MPA) onto gold followed covalent attachment to self-assembled monolayer using carbodiimide coupling. were characterized electrochemistry, a newly developed mass-spectrometry method and quantum mechanical calculations. mass spectrometry confirmed proceed as expected peptide bonds formed...
