Summary: Eu3+, Cr3+ doped and co-doped LaVO4 phosphors were prepared through a high temperature solid-state reaction method. The XRD patterns of the phosphors were sharp and intense, indicating a highly crystalline nature. The existence of La, Eu, Cr, V and O elements was confirmed by EDS spectra. The optical properties of the phosphors were influenced by the concentration of Cr3+ ion. The co-doped phosphors exhibited emission bands from both Eu3+ and Cr3+ ions. The energy transfer from Eu3+ to Cr3+ ions reduced the emission intensity of Eu3+ doped phosphor. The Eu3+, Cr3+ co-doped LaVO4 phosphor also exhibited heat generation upon excitation. These phosphors have potential applications in LEDs, solid state lighting and heat generating devices.

Summary: Hybrid organic-inorganic 2-D perovskite bis-benzylammonium lead tetrachloride (BALC) is a room-temperature ferroelectric semiconductor with a structural phase transformation under pressure. The high-pressure transition is attributed to distortion in the PbCl6 octahedra and conformation changes in the molecule, leading to rearrangements in the hydrogen bond network. BALC's ferroelectricity is expected to be lost above approximately 1.8 GPa due to a centrosymmetric structure in the new phase.

Summary: This study investigated the effect of pressure on the structure of lamivudine using Raman and infrared spectroscopy in diamond anvil cells. The results demonstrated a transition from tetragonal crystal Form II to an unknown Form III' at approximately 1.26 GPa, followed by a transition from Form III' to Form IV' at a pressure of 7.23 GPa. These phase transitions were characterized by distinct profiles and pressure-dependent characteristic modes. The changes in structural symmetry caused by pressure led to a conformational transition in lamivudine. Additionally, there was significant conformational variation between A and D within the lamivudine molecule to maintain structural balance. Spectroscopic measurements indicated that these pressure-induced changes were reversible below approximately 0.1 GPa.

Summary: A one-pot co-pyrolysis strategy using potassium/calcium carbonate and biowaste-derived hydrochar was proposed to prepare hierarchical porous biochars (HPBs). The pore structure of HPBs could be controlled by adjusting the mass ratios of different carbonates. HPBs exhibited hydrophobicity, nitrogen doping, graphitization, and surface functional groups, and showed unexpectedly high sorption quantity for diethyl phthalate. The sorption mechanisms were identified as Lewis acid-base interaction, pi-pi stacking interaction, hydrogen bonding interaction, partitioning, and pore filling.

Summary: In this work, the pressure-induced phase transitions of N2H4BH3 were studied using vibrational spectroscopy, X-ray diffraction, and density functional theory (DFT). It was found that N2H4BH3 exhibits remarkable structural stability up to 15 GPa, followed by two phase transitions. DFT calculations revealed that the stability of N2H4BH3 and the late phase transformations are related to the pressure-mediated evolutions of dihydrogen bonding frameworks, the compressibility, and the enthalpies of the high-pressure polymorphs. These findings provide important insights into the structures and bonding properties of N2H4BH3 for hydrogen storage applications.

Summary: The 20NaF-60P2O5-20Na2O fluorophosphate glass systems doped with 3 wt% of CoO and NiO were investigated for their optical parameters before and after gamma irradiation. The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
