Commonly, the oxygen molecule is first adsorbed on the catalyst surface to form adsorbed OOH (∗OOH), which becomes HOOH or undergoes O–O bond cleavage to form ∗O [8,14]. SACs and DACs have been developed to
Immune cells (myeloid cells or lymphoid cells) play a crucial role in regulation of tumor immunity within the tumor immune microenvironment (TME) [26]. The TME has the capacity to reprogram neutrophils, enabling them to engage in cross-signaling with tumor cells and consequently alter the immune...
(b) Fluorescent signal intensity as a function of quantum dot loading concentration. Fluorescence was integrated over a circle of radius 30 µm centred on the triangular particles. Each point represents mean measurement from three particles; error bars represent standard deviation. (c) NIR-...
Tai Chi diagram: production and elimination of ROS. ROS are mainly generated from the mitochondrial electron transport chain and as by-products of several cellular enzymes, including NOX, XOR, and LOX. To maintain balance, ROS is controlled with the help of antioxidant networks. The ROS eliminati...
In order to prove the photocatalytic reaction mechanism mentioned above, the free energy diagrams for the H2 evolution reaction were calculated firstly, in which the chemical potential of a proton/electron (H++e−) is equal to half of that one H2 gas molecule (Cu-OV-TpPa-A was chosen to...

The generation of ROS involves the energy transfer from a photosensitizer to the oxygen molecule upon light irradiation. The whole photosensitization process is complex but can be simplified using the Jablonski diagram as shown in Fig.1a. When a photosensitizer molecule is irradiated by appropriate inc...
Oxygen evolution reaction (OER) plays an undoubtedly vital role in the energy conversion system, which involves hydrogen production through water electrolysis, CO2 reduction to generate clean small molecule fuel, and the application of energy conversion devices such as metal-air batteries1–4. As a ...
andσλis the photodissociation cross-section30. Figure4collects together the wavelength dependences of the solar photon flux in the early period31, the total photoabsorption cross-sections of the parent H2O molecule in the VUV region (90–200 nm)32and the production yields of O atoms at st...
Also included within the term “protein” are “compound proteins,” wherein a protein molecule is united with a nonprotein molecule, such as nucleoproteins, mucoproteins, lipoproteins and metalloproteins. The proteins may be naturally-occurring, synthetic or semi-synthetic. “Surfactant” refers to...
