Evaluating Numerical Methods to Investigate Spectral Solar Radiative Transfer in Plant Canopies

open access: yesJournal of Advances in Modeling Earth Systems
The disposition of spectral solar irradiance in plant canopies is crucially important to understand processes such as photolysis of molecules amenable to absorbing actinic light.

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

Synergistic Modulation of Conductivity and Oxidation Stability in SiHfBCN Ceramics via UV‐Assisted Structural Evolution

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A quinary UV‐curable SiHfBCN ceramic photoresist with high ceramic yield enhanced is developed through sequential molecular design for high‐temperature sensing coatings. The elevated interconnected conductive network induced by chemically bonded carboxylated MWCNTs enables the pyrolyzed ceramics' enhanced conductivity and excellent oxidation stability.

Phenolate‐ and Alcoholate‐Based Chromium N‐Heterocyclic Carbene Complexes: Structural Peculiarities, Magnetometric and Electron Paramagnetic Resonance Study, and Catalytic Ethylene Oligomerization

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The first low‐oxidation (I/III) state chromium‐complex bearing a O‐chelating NHC ligand has been synthesized and structurally characterized by single‐crystal X‐ray analysis. The formation of the mixed‐valence species was further supported by SQUID magnetometry and high‐field electron paramagnetic resonance (EPR) spectroscopy.

FORMATION OF DIAMAGNETIC PRODUCTS IN CRYSTALLINE NITRATES UNDER THE ACTION OF LIGHT QUANTA WITH THE ENERGY OF 5.58 EV

open access: yesВестник Кемеровского государственного университета, 2014
The photolysis of potassium, rubidium and cesium crystalline nitrates under light with the photon energy of 5.58 eV was investigated. Nitrite and peroxynitrite are the photolysis end-products.

Kinetics of the photolysis of benzenetricarbonylchromium(0) in chloroform [PDF]

open access: yes, 2000
In contrast to the photolysis of Cr(CO)3(C6H6) in nonhalogenated solvents, in which the products are CrL(CO)2(C6H6) in the presence of a donor L, or Cr(CO)6 and C6H6 if no donor is present, the photo-reaction in chloroform yields CrCl3.

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...
