Bacterial cellulose (BC) is a biodegradable nanoscale film produced by microorganisms, which possesses great mechanical properties and biocompatibility. In this study, we produced foaming BC (FBC) utilizing foam medium with different concentrations of agar. In addition, carvacrol was loaded into the agar/FBC to establish active packaging material. Evaluation by characterization tests indicated that agar/FBC provided lower crystallinity (59.8%∼71.4%) and a high swelling ability (94.7%∼97.9%) compared to BC (92.2% and 96.1%). The 1.5% agar/FBC with carvacrol group exhibited the significantly highest antimicrobial properties against Escherichia coli and Staphylococcus aureus. Moreover, release measurements showed that greater agar addition contributed to higher protein and carvacrol release extents out of the film. Finally, a sea bass packaging test indicated that carvacrol with 1.5% agar/FBC presented a higher antimicrobial ability against Shewanella putrefaciens, great inhibition of lipid oxidation (67.5%), and a slower spoilage degree (49.8%) which suggested that agar/FBC with carvacrol has potential for active food packaging. © 2024 Elsevier Ltd

Increasing global environmental deterioration is becoming a serious concern, leading to an exponential increase in scientific interest in renewable energy as an alternative to replace fossil fuels. Photoelectrochemical (PEC) water splitting, which directly converts sunlight into hydrogen fuel, offers a promising renewable energy technology. Semiconductors, used as photoelectrodes, provide the most feasible method for converting solar energy into electrical energy and chemical fuels. Unfortunately, most of the common semiconductors used in PEC water splitting have wide bandgaps, which greatly restrict the utilization efficiency of sunlight. To promote the solar-to-hydrogen (STH) efficiency of PEC water splitting, atomically precise clusters with regular crystal structures have been introduced in the PEC systems. In this review, the recent advances in nanoclusters for PEC water splitting, including metal clusters, polyoxometalates, semiconductor clusters, and carbon clusters, are summarized. At last, major challenges and outlook for the development of clusters for PEC water splitting are provided.

Molten salts play a crucial role in Generation IV nuclear energy technology, with chloride salts like NaCl-UCl 3 garnering significant attention due to their distinctive properties and potential applications in fast-spectrum molten salt reactors (MSRs). The corrosive nature of molten salts can cause the dissolution of structural materials, leading to the formation of new species in molten chlorides. In addition, the radioactive decay of nuclear fuels results in the accumulation of fission products in the salts. Understanding the behavior of these corrosion and fission products and their impacts on the properties of molten salts is critical for the design of MSRs. This paper presents a systematic study on the properties of eutectic NaCl-UCl 3 molten salt in the presence of corrosion products (CrCl 2 and CrCl 3 ) and fission products (CsCl and SrCl 2 ) utilizing ab initio molecular dynamics (AIMD) simulations. We focus on essential structural and thermophysical properties such as density, mixing energy, coordination numbers (CN), and Radial Distribution Functions (RDF) with varying compositions of these corrosion and fission products from 0 % to 15.8 %. It is found that the mixing behavior of these corrosion and fission products is strongly driven by their coordination chemistry in eutectic NaCl-UCl 3 . Both CrCl 2 and SrCl 2 have identical coordination to eutectic NaCl-UCl 3 , thus exhibit negative mixing energies at a lower concentration. In contrast, CsCl exhibits significant different coordination compared to NaCl-UCl 3 , resulting to positive mixing energies. Our results offer valuable insights into the coordination chemistry and mixing behavior of corrosion and fission products in chloride molten salts and provide essential data that can be used as input to property databases to supplement experimental data.

Photo-Controlled Calcium Overload from Endogenous Sources for Tumor Therapy

Designing reactive calcium-based nanogenerators to produce excess calcium ions (Ca 2+ ) in tumor cells is an attractive tumor treatment method. However, nanogenerators that introduce exogenous Ca 2+ are either overactive incapable of on-demand release, or excessively inert incapable of an overload of calcium rapidly. Herein, inspired by inherently diverse Ca 2+ -regulating channels, a photo-controlled Ca 2+ nanomodulator that fully utilizes endogenous Ca 2+ from dual sources was designed to achieve Ca 2+ overload in tumor cells. Specifically, mesoporous silica nanoparticles were used to co-load bifunctional indocyanine green as a photodynamic/photothermal agent and a thermal-sensitive nitric oxide (NO) donor (BNN-6). Thereafter, they were coated with hyaluronic acid, which served as a tumor cell-targeting unit and a gatekeeper. Under near-infrared light irradiation, the Ca 2+ nanomodulator can generate reactive oxygen species that stimulate the transient receptor potential ankyrin subtype 1 channel to realize Ca 2+ influx from extracellular environments. Simultaneously, the converted heat can induce BNN-6 decomposition to generate NO, which would open the ryanodine receptor channel in the endoplasmic reticulum and allow stored Ca 2+ to leak. Both in vitro and in vivo experiments demonstrated that the combination of photo-controlled Ca 2+ influx and release could enable Ca 2+ overload in the cytoplasm and efficiently inhibit tumor growth.

Exciton Bohr radius (ab) and exciton binding energy (eb) of metal halide perovskites are two prime quantities in their applications to both light-emitting diode displays and photovoltaic devices. We develop a reliable theoretical method of simultaneously finding ab and erc (dielectric constant) based on the net exciton energy above the bulk band gap. It is estimated that ab under the dielectric confinement is substantially smaller than ab in the absence of dielectric confinement: 4.36 nm vs. 5.61 nm in the case of CH3NH3PbBr3. We attribute the enhanced ab to variations of erc and the electron-hole correlation energy. We also develop a simple method of finding eb based on the same net exciton energy. Using this, we attribute the well-known difference in eb between organic bromide perovskites and iodide counterparts to ecc and explain that iodide perovskites are more suited than bromide counterparts in photovoltaic applications, which require smaller eb for efficient charge-carriers transport. © 2025, CC BY.

Various contaminants, including diverse contaminants of emerging concern (CECs) can be found in nowadays aquatic environment, possessing a high potential to cause adverse ecological and human health effects. Due to recalcitrance of these contaminants, conventional water treatment methods are shown to be inadequately effective. Thus, their upgrade by photooxidative process, i.e. advanced oxidation processes, involving the generation of highly reactive species (HO•and SO4-•), is highly demanded. However, in order to determine the corresponding reaction rate constants the complex experimental studies has to be maintained. The alternative is the application of modeling approaches which correlate structural characteristics with activities/properties of interest, i.e. quantitative structure activity/property relationship (QSAR/QSPR). The discussed studies in this chapter were aimed at developing a number of models simulating the photooxidative degradation of aromatic compounds. In discussed works the hypothesis of the structural dependence of degradation kinetics was tested by combined mechanistic and structure-property relationship modeling approach. The applied combined approaches were able to yield a high accuracy in simulating the overall system behavior, accurately predicting the effectiveness of UV/H2O2 process by the means of parent pollutant conversion and mineralization of overall organic content. The QSPR models allowed to elucidate key structural features promoting degradation of investigated organic contaminants. © 2019 American Chemical Society. All rights reserved.

Interfacial interactions are crucial in a variety of fields and can greatly affect the electric, magnetic, and chemical properties of materials. Among them, interface orbital hybridization plays a fundamental role in the properties of surface electrons such as dispersion, interaction, and ground states. Conventional measurements of electronic states at interfaces such as scanning tunneling microscopes are all based on electric interactions which, however, suffer from strong perturbation on these electrons. Here we unveil a new experimental detection of interface electrons based on the weak magnetic interactions between them and the nitrogen-vacancy (NV) center in diamond. With negligible perturbation on the interface electrons, their physical properties can be revealed by the NV spin coherence time. In our system, the interface interaction leads to significant decreases in both the density and coherence time of the electron spins at the diamond-graphene interface. Furthermore, together with electron spin resonance spectra and first-principle calculations, we can retrieve the effect of interface electron orbital hybridization. Our study opens a new pathway toward the microscopic probing of interfacial electronic states with weak magnetic interactions and provides a new avenue for future research on material interfaces.
