Preparation and Application of Modified Vermiculite Adsorption Materials

open access: yesKuangchan zonghe liyong
β-Cd polymer (KACD) was prepared by modifying β-Cd with KH560 at alkaline conditions, and then the polymer was loaded onto vermiculite to prepare β-Cd modified vermiculite composite (KACDS).

syn-Selective alkylarylation of terminal alkynes via the combination of photoredox and nickel catalysis

open access: yesNature Communications, 2018
Converting alkynes into alkenes with high stereoselectivity via two consecutive C-C bond forming steps is a desirable process, yet very challenging. Here, the authors describe a dual photoredox-nickel catalytic system for the regio- and syn-selective ...

Preparation of Solution Blown Polyamic Acid Nanofibers and Their Imidization into Polyimide Nanofiber Mats

open access: yesNanomaterials, 2017
Solution blow spinning (SBS) is an innovative process for spinning micro/nanofibers. In this paper, polyamic acid (PAA) nanofibers were fabricated via a SBS apparatus and then imidized into polyimide (PI) nanofibers via thermal process.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Photoredox-catalyzed branch-selective pyridylation of alkenes for the expedient synthesis of Triprolidine

open access: yesNature Communications, 2019
Alkenylpyridines are versatile building blocks for the synthesis of drugs and other complex molecular structures. Here, the authors show a branch-selective pyridylation of alkenes via sulfinate-assisted photoredox catalysis and showcase its utility in an

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Controllable large-scale processing of temperature regulating sheath-core fibers with high-enthalpy for thermal management

open access: yesNano Materials Science
Temperature regulating fibers (TRFs) with high enthalpy and high form stability are the key factors for thermal management. However, the enthalpies of most TRFs are not high, and the preparation methods are still at the laboratory scale.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
