Conformational cooling and conformation selective aggregation in dimethyl sulfite isolated in solid rare gases [PDF]

Journal of Molecular Structure, 2006
Abstract Dimethyl sulfite has three conformers of low energy, GG, GT and GG′, which have significant populations in the gas phase at room temperature. According to theoretical predictions, the GT and GG′ conformers are higher in energy than the GG conformer by 0.83 and 1.18 kJ mol−1, respectively, while the barriers associated with the GG′→GT and GT ...

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

FEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Simultaneous optimization in plastic injection molding for weldline temperature and clamping force

Nihon Kikai Gakkai ronbunshu, 2017
In plastic injection molding (PIM), the process parameters such as melt temperature, mold temperature, injection time, and so on strongly affect the energy consumption as well as the product quality.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
