Photoluminescent carbon dots (C-dots) were prepared using the improved nitric acid oxidation method. The C-dots characterized by tapping-mode atomic force microscopy, and UV-vis absorption spectroscopy. subjected to systematic safety evaluation via acute toxicity, subacute genotoxicity experiments (including mouse bone marrow micronuclear test Salmonella typhimurium mutagenicity test). results showed that successfully with good stability, high dispersibility, water solubility. At all studied...
A triangular Dy(III) single-molecule magnet (SMM) exhibiting ferroelectric bistability is assembled in an acentric space group Pna21. Hysteresis loops associated with its SMM behavior together a two-step slow relaxation of the magnetization are observed below 30 K. transition dielectric anomalies between paraelectric and phase occurs at 470
Materials that possess coupled magnetic and electric properties are of significant interest because their potential use in next-generation magnetoelectric devices such as digital information storage. To date, the materials have been studied in-depth limited mainly to inorganic oxides perovskite oxides. Molecular a promising alternative elements can be combined together at molecular level via relatively simple designs. Here, we report coupling through magnetodielectric (MD) effect...

Considering its high specific modulus, nanocellulose, including rigid cellulose nanocrystals (CNCs) and semiflexible nanofibrils (CNFs), is widely used as a nano-reinforcing filler for polymeric-based composites, which regarded the most promising application of these biomass nanoparticles. The quantitative evaluation compatibility dispersion/aggregation state nanocellulose in polymeric matrices critical issue, it conditions efficient stress transfer from matrix to effective mechanical...
Abstract Electrical control of magnetism in single-molecule magnets with peculiar quantum magnetic behaviours has promise for applications molecular electronics and computing. Nevertheless, such kind magnetoelectric effects have not been achieved materials. Herein, we report the successful realization significant by introducing ferroelectricity into a dysprosium-based magnet through spatial cooperation between flexible organic ligands halide ions. The stair-shaped magnetization hysteresis...
Benzophenone (BP) is an ultraviolet filter (UVF) widely used in personal care products such as sunscreens and cosmetics. Excessive exposure to BP-type UVFs a potential threat human's health because of their endocrine-disrupting activity. Water stability lanthanide compounds crucial when they serve luminescent sensors the practicality recyclability. In this study, water-stable Zn–Tb heterometallic coordination polymer was rationally designed synthesized for rapid detection BP. This material...
Generative models are rapidly gaining popularity and being integrated into everyday applications, raising concerns over their safe use as various vulnerabilities exposed. In light of this, the field red teaming is undergoing fast-paced growth, highlighting need for a comprehensive survey covering entire pipeline addressing emerging topics. Our extensive survey, which examines 120 papers, introduces taxonomy fine-grained attack strategies grounded in inherent capabilities language models....
The room temperature photoluminescence property of ZnO particles embedded in sol–gel silica was investigated. Three emissions at about 3.25 eV (ultraviolet (UV)), 2.8 (blue), and 2.45 (green) were observed. blue green ascribed to interstitial zinc oxygen vacancy defects ZnO. At heating temperatures above 900°C, the interaction with SiO2 gave rise Zn2SiO4, which enhanced emission markedly by limiting oxidation process vacancy. Heating low pressure found enhance UV substantially. effects...
A hexagonal porphyrin-based porous organic polymer, namely, CPF-1, was constructed by 3+2 ketoenamine condensation of the C2 -symmetric porphyrin diamine 5,15-bis(4-aminophenyl)-10,20-diphenylporphyrin and 1,3,5-triformylphloroglucinol.

The ordering of polar hydrogen bonds may break space inversion symmetry and induce ferroelectricity or antiferroelectricity. This process is usually immune to external magnetic fields so that control very challenging. Here we demonstrate the in metal-organic frameworks $[{({\mathrm{CH}}_{3})}_{2}{\mathrm{NH}}_{2}]M{(\mathrm{HCOO})}_{3}$ ($M=\mathrm{Fe}$, Co) can be manipulated by applying fields. After cooling a high field, order-disorder transition shifts lower higher temperature, depending...

Materials that coexist magnetic and electric properties on the molecular scale in single-molecule magnets (SMMs) with peculiar quantum behaviors have promise electronics spintronics. Nevertheless, such materials are limited potentials because their signal cannot be transformed into an electrical through magnetoresistance or Hall effects for high insulativity. The discovery of entirely new material, ferroelectric SMMs (FE SMMs) is reported. This FE SMM also shows behaviors, toroidal moments,...
Titanium doped sapphire (Ti:Al2O3) shows a 420 nm blue emission band whose corresponding excitation lies at 244 nm. With the aim of ascertaining origin this emission, using synchrotron radiation we measured vacuum ultraviolet to absorption spectrum titanium sapphire. It is suggested that due center other than trivalent Ti3+ ion or tetravalent Ti4+ ion, most probably an F+-type color formed in crystal.
