Phase‐Change Solvents for Thermally Switchable Ion Conduction in Organogels

open access: yesAdvanced Materials, EarlyView.
Organogels containing salts dissolved in phase‐change solvents exhibit thermally switchable ion conduction. The organogels, which display an over 10 000‐fold on‐off ratio and high cycling stability, can be synthesized with a wide range of salts and customizable conductivity/temperature relations for applications in ionotronics and energy storage ...

Asymmetric α-amination of β-keto esters using a guanidine–bisurea bifunctional organocatalyst

open access: yesBeilstein Journal of Organic Chemistry, 2016
An asymmetric α-amination of β-keto esters with azodicarboxylate in the presence of a guanidine–bisurea bifunctional organocatalyst was investigated. The α-amination products were obtained in up to 99% yield with up to 94% ee.

Spider Silk–Integrated Biomimetic Micropillars With Dual Adhesion for Improved Wound Hemostasis and Healing

open access: yesAdvanced Materials Technologies, EarlyView.
The patch mimics the dual physicochemical adhesion mechanisms of gecko toe micropillars and spider silk proteins, enabling strong interfacial bonding via partially cured micropillars. Its facile fabrication allows customization for precision medicine, while its motion responsiveness offers potential for real‐time wound monitoring.

Fluorescent Bis(guanidine) Copper Complexes as Precursors for Hydroxylation Catalysis

open access: yesInorganics, 2018
Bis(guanidine) copper complexes are known for their ability to activate dioxygen. Unfortunately, until now, no bis(guanidine) copper-dioxygen adduct has been able to transfer oxygen to substrates.

Controlled cortical impact traumatic brain injury in 3xTg-AD mice causes acute intra-axonal amyloid-β accumulation and independently accelerates the development of tau abnormalities [PDF]

open access: yes, 2011
Alzheimer\u27s disease (AD) is a neurodegenerative disorder characterized pathologically by progressive neuronal loss, extracellular plaques containing the amyloid-β (Aβ) peptides, and neurofibrillary tangles composed of hyperphosphorylated tau proteins.

EIF1AX Nucleolar Condensates Enhance Susceptibilities for the Management of Endometrial Cancer

open access: yesAdvanced Science, EarlyView.
This schematic illustrates the mechanism of a senolytic strategy in endometrial cancer. EIF1AX facilitates the incorporation of DDX21 into nucleolar condensates, an event that suppresses rDNA transcription and induces cellular senescence. The compound 2,5‐MeC exploits this pathway by promoting EIF1AX nucleolar translocation and condensate formation ...
