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‐

Plasmonic Water Splitting [PDF]

Science, 2013
Chemistry One issue in harvesting the energy in sunlight to split water for hydrogen generation is utilizing the lower-energy visible-light component. Mubeen et al. report on an integrated platform in which plasmons excited in gold nanorods (∼50 nm in diameter) create electron-hole pairs for driving the reaction.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

FEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Optimized Metal Chalcogenides for Boosting Water Splitting

Advanced Science, 2020
Electrocatalytic water splitting (2H2O → 2H2 + O2) is a very promising avenue to effectively and environmentally friendly produce highly pure hydrogen (H2) and oxygen (O2) at a large scale.

A hygroscopic nano-membrane coating achieves efficient vapor-fed photocatalytic water splitting

Nature Communications, 2022
Although light-driven water vapor splitting may avoid material stability challenges for renewable fuel production, material performances lag behind solution-based studies.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Hybrid bio-photo-electro-chemical cells for solar water splitting

Nature Communications, 2016
Photoelectrochemical water splitting uses solar power to decompose water to hydrogen and oxygen. Here, the authors integrate thylakoid membranes extracted from spinach into a bio-photo-electro-chemical cell capable of overall water splitting without the ...
