Singlet and triplet doped-hole configurations in La_2Cu_0.5Li_0.5O_4

, 1996
The ordered alloy La_2Li_{0.5}Cu_{0.5}O_4 is found to be a band insulator in local density approximation (LDA) calculations with the unoccupied conduction band having predominantly d_{x^2-y^2}-symmetry and substantial weight in O 2p-orbitals.

Eutectozymes as Soft Hybrid Materials for Advanced Biocatalysis

Advanced Materials, EarlyView.
Eutectozymes are sustainable hybrid materials that embed a GOx–HRP cascade within hydrophobic eutectogels featuring a dual supramolecular–covalent network. This architecture preserves native enzyme structure and stability, enables efficient heterogeneous biocatalysis in aqueous media, and positions eutectogels as robust platforms for next‐generation ...

Wavelength dependence of the efficiency of singlet oxygen generation upon photoexcitation of photosensitizers

EPJ Web of Conferences, 2017
The dependence of the efficiency of singlet oxygen (1Δg) generation upon excitation of photosensitizer at different wavelength was observed for several derivatives of palladium porphyrin in carbon tetrachloride.

Effects of Edaravone on Singlet Oxygen Released From Activated Human Neutrophils

Journal of Pharmacological Sciences, 2007
The effects of edaravone, a curative agent for acute brain infarction, on singlet oxygen (1O2) released from activated human neutrophils were examined, and the effects were compared to those of histidine, a 1O2 singlet oxygen scavenger.

Orbital degeneracy as a source of frustration in LiNiO$_2$

, 2004
Motivated by the absence of cooperative Jahn-Teller effect and of magnetic ordering in LiNiO$_2$, a layered oxide with triangular planes, we study a general spin-orbital model on the triangular lattice.

Orbital Order Effect of Two-Dimensional Spin Gap System for CaV4O9

, 1997
Effects of possible orbital order in magnetic properties of two-dimensional spin gap system for CaV$_4$O$_9$ are investigated theoretically. After analyzing experimental data, we show that single orbital models assumed in the literature are insufficient ...
