Chemoselectivity in the Dehydrocoupling Synthesis of Higher Molecular Weight Polysilanes

open access: yes, 2010
The Cp2ZrCl2/2 BuLi catalyzed co-polymerization of H2MeSiSiMeH2 and PhSiH3 was compared to the homo-polymerization of H2MeSiSiPhH2. In contrast to the co-polymerization, which gave molecular weights comparable to homo-polymerization of phenylsilane, the ...

Molecular Weight Discrete Distribution-Induced Orientation of High-Strength Copolyamide Fibers: Effects of Component Proportion and Molecular Weight

open access: yes, 2021
The mechanical properties of polymer fibers are dependent on the molecular chemical structure and condensed state structure. Effective control over these two structural parameters allows us to study the relationship between fiber structures and ...

Characteristics and transformations of dissolved organic nitrogen in municipal biological nitrogen removal wastewater treatment plants

open access: yesEnvironmental Research Letters, 2013
Dissolved organic nitrogen (DON) represents most of the dissolved nitrogen in the effluent of biological nitrogen removal (BNR) wastewater treatment plants (WWTPs). The characteristics of wastewater-derived DON in two different WWTPs were investigated by

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Copurification of chicken liver soluble thiamine monophosphatase and low molecular weight acid phosphatase

open access: yes, 2017
Thiamine monophosphatase (ThMPase) is an enzyme of thiamine metabolism in animals whose molecular nature has still to be elucidated. In this study we have achieved a 714-fold purification of a soluble enzyme possessing ThMPase activity from a chicken ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Prediction of Bitumen Molecular Weight Distribution Using Rheological Property [PDF]

open access: yes, 2013
: There are some problems to find heavy hydrocarbon characteristic such as lake of method or techniques and the special hydrocarbon property. Therefore, it is important to obtain the relation to find heavy hydrocarbon characteristic analytically or by ...

Enzymic hydrolysis of chickpea protein by Alcalase and its antioxidative activities

open access: yes浙江大学学报. 农业与生命科学版, 2007
The optimal conditions for enzymatic hydrolysis of chickpea protein, the antioxidative activity, free radical scavenging activities and molecular weight distribution of the chickpea protein hydrolysates were studied.

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

On the quantitative click conjugation of molecular weight distributions: what can theoretically be expected?

open access: yes, 2009
The assessment of the success of a click conjugation for block copolymer formation often occurs via ill-defined criteria based on the qualitative shape of the size exclusion chromatography (SEC) distribution as well as unsuitable characteristics of these
