Modeling and Improving Geometric Accuracy in Projection Multiphoton Lithography

Advanced Optical Materials, EarlyView.
A numerical framework describing the optical and photochemical processes is developed to elucidate the origins of geometric deviations in projection multiphoton lithography. The results indicate that oxygen diffusion and inhibition, and DMD diffraction, lead to geometric distortions.

Thiosulfonate‐Derived BODIPY “Stick and Glue” Strategy for Fluorescent Thiol Labeling

Angewandte Chemie, EarlyView.
We present a powerful photochemical strategy for converting disulfide bonds into stable thioether linkages via a [1,2]‐sigmatropic rearrangement. By integrating this reaction into traditional methanethiosulfonate‐based thiol labeling, we enable light‐triggered stabilization of peptide and protein conjugates with enhanced robustness and versatility ...

Photolysis of a Caged, Fast-Equilibrating Glutamate Receptor Antagonist, MNI-Caged γ-D-Glutamyl-Glycine, to Investigate Transmitter Dynamics and Receptor Properties at Glutamatergic Synapses

Frontiers in Cellular Neuroscience, 2018
Fast uncaging of low affinity competitive receptor antagonists can in principle measure the timing and concentration dependence of transmitter action at receptors during synaptic transmission.

Effects of UV-A Light Treatment on Ammonia, Hydrogen Sulfide, Greenhouse Gases, and Ozone in Simulated Poultry Barn Conditions

Atmosphere, 2020
Gaseous emissions, a side effect of livestock and poultry production, need to be mitigated to improve sustainability. Emissions of ammonia (NH3), hydrogen sulfide (H2S), greenhouse gases (GHGs), and odorous volatile organic compounds (VOCs) have a ...

Light-Induced Orthogonal Reactivity of Photoinitiators from One-Electron Reduction to Nanocomposites. [PDF]

Angew Chem Int Ed Engl
Irradiating a mixture of a photoinitiator, a metal salt, and a monomer in an alcoholic solvent or aqueous solution provides a plasmonic polymer‐metal nanocomposite in a highly convenient way. Abstract Photoinitiators for radical polymerization have been well established.

OH yields from the CH3CO+O-2 reaction using an internal standard [PDF]

, 2007
Laser flash photolysis of CH3C(O)OH at 248 nm was used to create equal zero time yields of CH3CO and OH. The absolute OH yield from the CH3CO + O2 (+M) reaction was determined by following the OH temporal profile using the zero time OH concentration as ...

A GLUTAMATE CYSTEINE LIGASE Gene StGSH1 Regulated by StERF10 Enhanced Glutathione Accumulation and Adaptation to Low Phosphorus Stress in Potato

Advanced Science, EarlyView.
The StERF10‐StGSH1 module coordinates glutathione (GSH) biosynthesis under low‐phosphorus stress. The low‐phosphate‐induced AP2/ERF transcription factor StERF10 directly activates the transcription of StGSH1 and enhances GSH accumulation. Consequently, GSH scavenges reactive oxygen species and provides sulfur for sulfolipid synthesis, facilitating the ...

Tunable Charge Transport Properties Through Precise π‐Stacking Modulation in Isostructural Porous Molecular Conductors

Angewandte Chemie, EarlyView.
An intrinsic structure–property relationship in through‐space conductive MOFs is investigated using a series of counterion‐free porous molecular conductors (PMC‐3) with carrier‐doped π‐stacked columns. The constant carrier density and halide‐dependent tunable π‐stacking geometry in PMC‐3 enable the discovery of a linear correlation between the lattice ...

A general kinetic model for the photothermal oxidation of polypropylene [PDF]

, 2014
A general kinetic model for the photothermal oxidation of polypropylene has been derived from the basic auto-oxidation mechanistic scheme in which the main sources of radicals are the thermolysis and photolysis of the most unstable species, i.e ...
