Summary: We report a novel approach to determine the spatially resolved nuclear spin-lattice relaxation times and NMR line widths in nanomaterials. We applied this approach to detonation nanodiamonds with manganese ions grafted onto their surface and observed the acceleration of nuclear spin-lattice relaxation and broadening of the resonance line. By using spin dephasing experiments, we were able to determine the contribution of paramagnetic Mn2+ ions to the relaxation time and line width of carbon spins at different depths from the diamond surface. Developed specifically for nanodiamonds, this approach can be applied to study distribution of relaxation rates and line broadening, and map magnetic interactions inside various nanoparticles, making it valuable in nanotechnologies.

Summary: High concentration of negatively charged nitrogen-vacancy (NV-) centers was successfully created in diamond single crystals containing approximately 100 ppm nitrogen using electron and neutron irradiation and subsequent thermal annealing. The formation process and properties of NV- centers were observed, with about 25% of vacancies forming NVs during the annealing process, and high precision measurement of hyperfine and quadrupole coupling constants was achieved using EPR techniques.

Summary: In this study, experimental observations of P-31 and H-1 NMR resonances shifted by over 10 000 ppm in a square planar ferrous complex were reported. The influence of magnetic anisotropy and zero-field splitting on paramagnetic shift and relaxation enhancement was investigated using various techniques, and spin dynamics simulations showed the possibility of observing NMR signals of directly metal-bonded atoms even with relatively slow electron spin relaxation.

Summary: The interaction between central qubit spin and surrounding bath of spins is crucial for quantum sensing and quantum information processing. By rotating a diamond at speeds up to 300,000 rpm, researchers have found that the interaction between electron spins of nitrogen-vacancy centers and a bath of C-13 nuclear spins introduces decoherence into the system. These findings offer new insights into using physical rotation for quantum control in systems with motional and rotational degrees of freedom.

Summary: Nuclear magnetic resonance (NMR) spectroscopy provides atomic-level molecular structural information. However, in molecules containing unpaired electron spins, direct measurement of NMR signals is difficult. In this study, we demonstrate the use of miniature microwave resonators and miniature NMR coils to excite and detect a wide bandwidth of electron-nuclear double resonance (ENDOR) data in a single pulse. This approach improves spectral resolution and allows for the measurement of ENDOR spectra with narrow lines spread over a large frequency range, revealing previously inaccessible details of the paramagnetic molecules' chemical structure.

Summary: Visible light exposure can cause photooxidation of protein formulations, leading to protein degradation. This study investigates the mechanism of photooxidation upon visible light exposure for therapeutic proteins. It is found that formation of reactive oxygen species (ROS) and singlet oxygen occurs, which induce protein degradation. The concentration of protein in the formulations affects the presence of a photosensitizer and the extent of protein degradation.

Summary: Cadmium germanium diphosphide (CdGeP2) crystals, belonging to the chalcopyrite family, have versatile terahertz-generating properties. CdGeP2 crystals exhibit unintentional intrinsic point defects including cadmium vacancies, phosphorous vacancies, and germanium-on-cadmium antisites. These defects can be studied using electron paramagnetic resonance (EPR) and optical absorption techniques. Illuminating CdGeP2 crystals with specific wavelengths of light at low temperatures produces different charged states of the defects. Additionally, exposure to near-band-edge light introduces broad optical absorption bands.

Summary: LL-III is an anticancer peptide that can translocate across tumor cell membranes. However, the mechanism through which it enters the cell cytoplasm is still unknown. In this study, we used physico-chemical techniques to characterize the interaction of LL-III with liposomes resembling the lipid matrix of the tumor cell membrane. Our results show that the peptide selectively interacts with the model tumor cell membrane without disrupting the lipid bilayer, but alters its properties by promoting lipid reorganization and increasing membrane permeability.

Summary: To protect human and environmental health, researchers are focusing on discovering and developing new molecules with high biocompatibility and biodegradability. Surfactants are particularly urgent in this matter, and biosurfactants derived from microorganisms are a promising alternative. Rhamnolipids, a well-known family of biosurfactants, have been extensively studied for their production and physicochemical characterization, although a clear structure-function relationship is still lacking. This review aims to provide a comprehensive discussion of the physicochemical properties of rhamnolipids under different solution conditions and their structure, while also addressing unresolved issues for their potential replacement of conventional surfactants.

Summary: The search for new synthetic melanin-related pigments with antioxidant and photoprotective properties is important for dermo-cosmetic purposes. In this study, a melanin derived from 5,6-dihydroxyindole-2-carboxylic acid (DHICA) was synthesized and found to have similar structural properties to DHICA melanin. The synthesized pigment demonstrated stronger UV-visible absorption and improved solubility compared to DHICA melanin. Furthermore, the pigment exhibited marked antioxidant properties and enhanced inhibitory action against lipid peroxidation. These findings suggest that the melanin derived from DHICA has potential as a functional ingredient in dermo-cosmetic formulations.

Summary: The ability of Methylobacterium extorquens to grow on methanol as the sole carbon and energy source is influenced by the composition and function of the lipopolysaccharide (LPS) in the outer membrane. The LPS of M. extorquens is unique, with non-phosphorylated and heavily O-methylated core oligosaccharides, and a distinctive lipid A structure. These chemical features impact the resistance of the membrane to methanol, regulating membrane ordering and dynamics.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
