Light-Driven Depolymerization of Native Lignin Enabled by Proton- Coupled Electron Transfer [PDF]
, 2019 Here we report a catalytic, light-driven method for the redox-neutral depolymerization of native lignin biomass at ambient temperature. This transformation proceeds via a proton-coupled electron-transfer (PCET) activation of an alcohol O–H bond to ...

Lignin-assisted coal depolymerization [PDF]
, 1991 Previous research has shown that addition of lignin-derived liquids to coal stirred in tetralin under mild reaction conditions (375{degree}C and 300--500 psig) results in a marked enhancement in the rate of coal depolymerization. A mathematical model was

Catalyst-free Depolymerization of Polycaprolactone to Silylated Monoesters and Iodide Derivatives Using Iodosilanes [PDF]
, 2023 The homogeneous depolymerization of polycaprolactone (PCL) with excess iodotrimethylsilane (Me3SiI) proceeds without catalysts and selectively afforded I(CH2)5CO2SiMe3 or a mixture of I(CH2)5CO2SiMe3 and I(CH2)5CO2I depending on the solvent (CH2Cl2 ...

Mechanocatalytic partial depolymerization of lignocellulosic feedstock towards oligomeric glycans [PDF]
, 2022 The depolymerization of lignocellulosic feedstock with a heterogeneous composition is a major challenge and usually leads to the formation of monosaccharides as main products.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Molecular Oncology, EarlyView.Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Lignin Depolymerization to Dicarboxylic Acids with Sodium Percarbonate [PDF]
, 2017 Lignin depolymerization to dicarboxylic acids (DCAs) by the one-step Fenton oxidation process results in poor yield and significant amounts of residual solids.

FEBS Open Bio, EarlyView.The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Effect of terahertz irradiation on DNA damage repair in living cells
FEBS Open Bio, EarlyView.We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.
