Thermal analysis of the prepared lignin/graphene oxide/polyurethane composite
Egyptian Journal of Petroleum, 2020 Lignin/graphene oxide/polyurethane composite was prepared for removing polyaromatics from wastewater. X-ray and TEM are used for the characterization of the prepared composite. Thermal analysis was carried out for two reasons. One reason to ascertain the

Deriving the Arrhenius Equation and the Pre-Exponential Factor
, 2023 Proposed in 1889 by Svante Arrhenius, the Arrhenius equation is an important result in physical chemistry which aims to find the relationship between temperature and reaction rates. It is also an essential equation for analytic chemistry which helps to determine the energy barrier for a given reaction.

High-Resolution Determination of Kinetic Parameters of Sucrose Hydrolysis Based on Weak Measurement
IEEE Photonics Journal, 2022 We propose a high-resolution scheme for determining the kinetic parameters of sucrose hydrolysis based on the weak measurement, and the parameters including rate constant, half-life, activation energy and pre-exponential factor are experimentally ...

Toward room-temperature nanoscale skyrmions in ultrathin films
npj Computational Materials, 2020 Breaking the dilemma between small size and room-temperature stability is a necessary prerequisite for skyrmion-based information technology. Here we demonstrate by means of rate theory and an atomistic spin Hamiltonian that the stability of isolated ...

Arginine methylation in subunits of mammalian pre-mRNA cleavage factor I [PDF]
, 2010 Mammalian cleavage factor I (CF Im) is composed of two polypeptides of 25 kDa and either a 59 or 68 kDa subunit (CF Im25, CF Im59, CF Im68). It is part of the cleavage and polyadenylation complex responsible for processing the 39 ends of messenger RNA ...

Molecular Oncology, EarlyView.We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...
