Simultaneous Determination of Lidocaine and Bupivacaine in Human Saliva Using Gas Chromatography-Mass Spectrometry

Arab Journal of Forensic Sciences & Forensic Medicine
Long-acting local anaesthetics have demonstrated effectiveness in managing intraoperative and postoperative pain. However, substances like lidocaine and paraben preservatives can trigger allergic reactions and methemoglobinemia in susceptible individuals.

Collective pairing hamiltonian in the GCM approximation [PDF]

Nuclear Physics A, 1985
Abstract Using the generator coordinate method and the gaussian overlap approximation we derived the collective Schrodinger-type equation starting from a microscopic single-particle plus pairing hamiltonian for one kind of particle. The BCS wave function was used as the generator function.

High‐performance tetrahedral palladium nanocatalyst for microwave‐assisted organic synthesis

Bulletin of the Korean Chemical Society, EarlyView.
Tetrahedral palladium nanoparticles anchored on graphene sheets (T‐Pd/graphene) were synthesized through a solvent‐free process involving thermal decomposition in an environment rich in carbon monoxide at elevated temperatures and have high catalytic activity for organic chemistry reactions. Abstract Palladium is widely recognized for its effectiveness

Coupled Photocatalytic Hydrogen Production With Selective Biomass Valorization via Active Sites Construction and Electron Transport Channels Engineering

Carbon Energy, EarlyView.
A ternary CdS/1T‐WS2/CNTs heterojunction is in‐situ constructed via hydrothermal method, which is used for photocatalytic biomass reforming (biomass‐derived alcohols, lignin). It exhibits outstanding performance: H2 production rate of 26.17 mmol/g/h for benzyl alcohol (BA), benzaldehyde (BD) generation rate of 8.29 mmol/g/h, 90.06% BD selectivity, 100%

Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles

Chemistry – A European Journal, EarlyView.
A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed

Cross‐Carboxylation of Methanol and Other Alcohols With CO2 Into Asymmetric Alkyl Methyl Carbonates Over a CeO2 Catalyst

Chemistry – A European Journal, EarlyView.
One‐pot synthesis of asymmetric organic carbonates from CO2, methanol, and other alcohols was demonstrated in the presence of CeO2 catalyst and 2‐cyanopyridine dehydrant. This reaction proceeded through two reaction pathways—direct route via cross‐carboxylation and indirect route via production of DMC and subsequent transesterification.

A Framework to Quantify the Uncertainty Contribution of GCMs Over Multiple Sources in Hydrological Impacts of Climate Change

Earth's Future, 2020
The quantification of climate change impacts on hydrology is subjected to multiple uncertainty sources. Large ensembles of hydrological simulations based on multimodel ensembles (MMEs) have been commonly applied to represent overall uncertainty of ...

Dilithium Enediamide Derived From a 1,4‐Diaza‐1,3‐diene: Reactivity of a Strongly N‐Basic, Highly C‐Nucleophilic Compound Toward C–H Acids

European Journal of Inorganic Chemistry, EarlyView.
The lithium enediamide complex 2 with intrinsically inverted C–N bond polarity combines strong basicity with unusual reactivity: deprotonation of malonates enables C–C bond formation without electron transfer. Depending on malonate substitution, electrophilic substitution or addition occurs at the enediamide CC bond.
