This review discusses organic semiconductors interfaced with biomolecular systems, focusing on the construction of material systems through biochemical pathways for device nanoarchitectonics. The initial section highligh...

Abstract The effect of Cu(II) ions on the decomposition of organic peroxides produced in the γ-radiolysis of threonine aqueous oxygenated solutions have been studied under various experimental conditions including diffe...

Highlights Establishes a unified framework linking the origins, descriptors, and catalytic functions of polarisation in covalent organic frameworks (COFs). Systematically categorises polarisation engineering strategies i...

We present HAlator, a fully automated quantum chemistry (QM) workflow for computing C–H hydricities and explore its potential in predicting the regioselectivity of electron-rich C–H functionalisation reactions. The w...

In this work we demonstrate the feasibility to couple adsorption with Fenton and photo-Fenton process to separate and mineralize crystal violet (CV) dissolved in water. Montmorillonite (MMT) and Iron modified Montmorill...

Co-doped titanium dioxide materials were successfully synthesized by the sol–gel method. Molybdenum was incorporated into all materials at 0.5 wt %, while the co-dopants, copper and cobalt, were added at 0.2–0.5 wt %...

The synthetic accessibility of fused pyridoazepane frameworks was investigated through a series of strategies designed to construct differently fused azepane systems. Several precursor designs enabling alternative ring-c...

Methane emissions and chemical pollutants often co-occur in natural and engineered environments, contributing to ecosystem degradation. Microorganisms play key roles in regulating these processes through methane oxidatio...

Metal-organic frameworks (MOFs) and their derivatives are found to be promising lithium-ion battery (LIB) anodes, yet their complex lithium storage mechanisms and kinetic behaviors remain insufficiently understood. In th...

Benthonic marine species show a wide range of biological reactions to seawater chemical changes through time, from subtle adjustments to extinction. The Early Toarcian Oceanic Anoxic Event (T-OAE) was recently recognized...

Sustainable development requires both CO2 emission reduction and management of existing greenhouse gases. Utilizing CO2 as a substrate in light-assisted catalytic reactions is promising, particularly with metal-organic f...

This article takes an educational perspective on a central limitation in biomass electrochemistry: the impossibility of driving multielectron reactions at the global thermodynamic potential. Standard electrode potentials...

A series of trifluoromethylated hexahydropyrimidines was synthesized using Preyssler heteropoly acid H14NaP5W29MoO110 encapsulated in a silica framework as the catalyst under solvent-free conditions. This synthesis requi...

Cyclodextrins (CDs)are a family of biodegradable cyclic hydrocarbons composed of α-(1,4)linked glucopyranose subunits, the more common containing 6, 7 or 8 glucose units are named α, β and γ-cyclodextrins respectivel...

Abstract Bimolecular nucleophilic substitution (SN2) and base-induced elimination (E2) reactions play crucial roles in chemistry. Here, we report a combined study of ion-molecule crossed-beam 3D velocity map imaging expe...

Along with the increasing requirement for efficient organic conversions using green chemistry, there is a need to develop highly efficient and eco-friendly catalytic reaction systems. Gold nanoparticles (AuNPs)-based nan...

In this article, common psychological problems of dialysis patients are presented. There are many organic, psychological and social problems which accompany the chronic renal failure. Beside changes of life style, the pa...

The reaction regimes under which proceed some of the relevant and deletereous consecutive reactions that occur during the conventional epoxidation process of vegetable oils were analyzed in detail, considering – separa...

Aluminum alloys are commonly subjected to chromatization to improve adhesion and protect against corrosion. However, this process is harmful to health and the environment. In this context, hybrid organic–inorganic sila...

Anions are ionic species that play important roles in biology, medicine, catalysis, and environmental science. Identifying these species is crucial for industrial applications and clinical diagnostics. In recent years, e...

The spin-trapping ESR (ST-ESR) method, which observes unstable radicals as stable spin adducts using electron spin resonance (ESR), is an effective experimental method for evaluating chemical reactions involving radical ...
