Materials Innovation and the Changing Face of Photocatalytic and Electrocatalytic Carbon Dioxide Reduction Research: From Metal Nanoclusters to Extended Frameworks The accelerating rise in atmospheric CO<sub>2</sub> levels, driven by anthropogenic emissions, underscores the urgent need for transformative carbon management strategies. Photocatalytic and electrocatalytic CO<sub>2</sub> reduction reactions (CO<sub>2</sub>RRs) offer a promising route to valorize CO<sub>2</sub> into energy-rich fuels and chemical feedstocks, yet the intrinsic thermodynamic and kinetic barriers necessitate catalysts that combine high activity, selectivity, and durability. Recent breakthroughs in materials chemistry have spotlighted two emerging material classes-atomically precise metal nanoclusters (NCs) and extended reticular frameworks such as metal-organic frameworks (MOFs) and covalent organic frameworks (COFs)-as frontiers for next-generation CO<sub>2</sub>RR catalysts. Both systems offer unparalleled opportunities to engineer active sites at the atomic and molecular levels, enabling precise modulation of local environments, electronic structures, and substrate interactions. This review brings these two materials paradigms under a common vision of precision-controlled catalysis, highlighting how innovations in cluster size, framework topology, and chemical functionality dictate product selectivity and C─C coupling behavior. We discuss emerging mechanistic insights, synthetic strategies, and structure-function relationships and outline challenges in conductivity, stability, and scalability. Finally, we propose integrated design principles to guide the development of hybrid platforms for efficient and selective CO<sub>2</sub> valorization.

Structure-Properties Correlations of PVA-Cellulose Based Nanocomposite Films for Food Packaging Applications Bio-nanocomposites based on poly (vinyl alcohol) (PVA) and cellulosic nanostructures are favorable for active food packaging applications. The current study systematically investigates the mechanical properties, gas permeation, and swelling parameters of PVA composites with cellulose nanocrystals (CNC) or nano lignocellulose (NLC) fibers. Alterations in these macroscopic properties, which are critical for food packaging applications, are correlated with structural information at the molecular level. Strong interactions between the fillers and polymer host matrix were observed, while the PVA crystallinity exhibited a maximum at ~1% loading. Finally, the orientation of the PVA nanocrystals in the uniaxially stretched samples was found to depend non-monotonically on the CNC loading and draw ratio. Concerning the macroscopic properties of the composites, the swelling properties were reduced for the D1 food simulant, while for water, a considerable decrease was observed only when high NLC loadings were involved. Furthermore, although the water vapor transmission rates are roughly similar for all samples, the CO<sub>2</sub>, N<sub>2</sub>, and O<sub>2</sub> gas permeabilities are low, exhibiting further decrease in the 1% and 1-5% loading for CNC and NLC composites, respectively. The mechanical properties were considerably altered as a consequence of the good dispersion of the filler, increased crystallinity of the polymer matrix, and morphology of the filler. Thus, up to ~50%/~170% enhancement of the Young's modulus and up to ~20%/~50% enhancement of the tensile strength are observed for the CNC/NLC composites. Interestingly, the elongation at break is also increased by ~20% for CNC composites, while it is reduced by ~40% for the NLC composites, signifying the favorable/unfavorable interactions of cellulose/lignin with the matrix.

Surface engineering of nano magnesium alloys for orthopedic implants: a systematic review of strategies to mitigate corrosion and promote bone regeneration Magnesium (Mg) alloys are transformative candidates for biodegradable orthopedic implants due to their bone-mimetic elastic modulus (10-30 GPa), biocompatibility, and osteogenic properties. However, rapid corrosion (>2 mm/year) and hydrogen gas evolution (0.1-0.3 mL/cm<sup>2</sup>/day) in physiological environments hinder clinical adoption. This systematic review, leveraging insights from seven databases (PubMed<sup>®</sup>, Embase, Web of Science™, Scopus<sup>®</sup>, IEEE Xplore, FSTA, and Google Scholar), critically evaluates surface engineering innovations that address these challenges. Key findings demonstrate that micro-arc oxidation (MAO) reduces corrosion rates by 60% (0.3-0.8 mm/year) through ceramic oxide layers, while hydroxyapatite (HA) coatings further enhance osteoconductivity (0.25 mm/year). Nanoscale MgO not only promotes osteoblast adhesion (40% increase) and collagen synthesis but also reduces bacterial colonization by 78% via surface energy modulation, eliminating antibiotic dependency. Advanced strategies like hybrid coatings (e.g., zwitterionic polymers) and alloying with Zn/Ca/Sr synergistically improve mechanical strength (up to 380 MPa), degradation control (0.1-0.5 mm/year), and angiogenesis via Mg<sup>2+</sup>-mediated VEGF upregulation. Emerging trends such as 4D bioprinting of pH-responsive Mg scaffolds and patient-specific implants highlight the shift toward dynamic, personalized solutions. Despite progress, challenges persist in synchronizing degradation with bone healing timelines, particularly in osteoporotic or diabetic patients. This review underscores the paradigm shift toward nano surface engineering, positioning Mg alloys as multifunctional platforms for next-generation orthopedic implants, while advocating for interdisciplinary collaboration to bridge translational gaps.

Achieving Efficient Blue Room‐Temperature Phosphorescence Through Self‐Doping of Similar Structures and Polymer Assistance Abstract Blue is one of the three primary colors, and it is a crucial element in the regulation and application of organic room‐temperature phosphorescence (ORTP). However, the considerable Stokes shift of small organic molecules presents a challenge for creating blue afterglow materials. To address this, host‐guest‐doped materials are prepared by selecting compounds with similar structures for self‐doping. This method effectively regulated blue organic long‐lasting phosphorescence. Additionally, the persistent‐RTP and organic long‐persistent luminescence (LPL) properties can be further enhanced by incorporating a rigid or flexible polymer network, creating a dense environment between the host and guest. Remarkably, the phosphorescence lifetime and afterglow duration of polymer‐assisted doped materials are ≈5 times greater than those of host‐guest doped crystal materials. Apart from its high efficiency, environmental friendliness, and easy synthesis, this blue ORTP material boasts high thermal stability and flexibility. Furthermore, this blue material demonstrates considerable potential in applications such as information encryption and anti‐counterfeiting across various media, including paper, cotton thread, and leaves.

Titanium dioxide nanoparticles augment Ciprofloxacin activity via Inhibition of biofilm formation for multidrug resistance bacteria in-vitro and insilco prediction study The increasing of multi-drug among pathogenic microbes is rendering antibiotics ineffective. Consequently, efforts are now concentrated on addressing this challenge through developing novel antibiotics and enhancing existing ones. This study combined ciprofloxacin (CIP) with titanium dioxide nanoparticles (TiO<sub>2</sub>NPs). We characterized the prepared nanoparticles (NPs) using several methods, including UV-Vis spectra, XRD, FESEM, TEM, and FTIR. The well diffusion agar was used to study the antibacterial activity of ciprofloxacin (CIP) alone and combined with titanium dioxide nanoparticles CIP@TiO<sub>2</sub>NPs. CIP@TiO<sub>2</sub>NPs showed higher antibacterial activity against Klebsiella pneumoniae (K.pneumoniae) and Streptococcus mutans S.mutans. The CIP@TiO<sub>2</sub>NPs showed remarkable inhibitory properties compared to CIP alone and TiO<sub>2</sub>NP alone, with its inhibition zone 28.50 ± 0.20 and 17.50 ± 0.10 in K.pneumoniae and S.mutans, respectively. Insilico study was done on bacterial strains to describe the effective binding behavior towards the ciprofloxacin@TiO<sub>2</sub> adsorption system. The best conformers, from 50 conformational adsorption systems, were analyzed with a significant favorable inhibition with binding energy values of -9.61 kcal/mol and - 9.40 kcal/mol with K.pneumoniae and S. mutans, respectively. The interaction between CIP@TiO<sub>2</sub>NPs nanoparticles and Klebsiella pneumonia (ID: 8JGW) was studied using 50 conformations. The results showed binding energies up to -9.61 kcal/mol, indicating high interaction efficacy. Compared to TiO<sub>2</sub>NPs and CIP alone, CIP@TiO<sub>2</sub>NPs displayed the highest antibacterial and anti-biofilm properties against pathogenic bacteria. CIP@TiO<sub>2</sub>NPs have demonstrated promising results, suggesting that they may prove to be a dependable treatment for K. pneumoniae and S.mutans in the future and a possible agent for reducing bacterial biofilm during bacterial infections.

Hepatotoxicity of Nanoparticle-Based Anti-Cancer Drugs: Insights into Toxicity and Mitigation Strategies Despite significant progress in developing novel, efficient nanoparticle-based anticancer drugs, hepatotoxicity remains a major challenge. The liver, as the primary organ responsible for detoxification, is particularly susceptible to nanoparticle accumulation, particularly through the action of Browicz-Kupffer cells (B-KCs) and liver sinusoidal endothelial cells (LSECs). These phagocytic cells accumulate nanoparticles, leading to the production of reactive oxygen species (ROS), interleukin 1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α), which ultimately cause hepatocyte damage. In recent years, various nanoparticle modification strategies have been investigated to reduce hepatotoxicity. One of the most common and effective approaches is the PEGylation of liposomes and graphene nanoparticles, which decreases their uptake by the liver via the reticuloendothelial system (RES). Other strategies to mitigate hepatotoxicity are also being explored, including the incorporation of negatively charged lipids into liposomes, charge manipulation of inorganic-organic nanoparticles, the use of specific protein-based nanoparticles that selectively bind to cancer cells (thereby reducing hepatic uptake), the use of appropriate viral capsids in the production of virus-like protein-based drugs, and the manipulation of the size of protein, metal and graphene nanoparticles. Moreover, modifications aimed at pH-responsive drug release are employed in liposomes, self-assembled and graphene nanoparticles. This article discusses several types of nanoparticles used as carriers in currently approved therapies and explores potential strategies to minimize their hepatotoxicity.

Biomimetic Janus membrane with spongy channels for directional liquid transport Janus fiber membranes enable directional liquid transport (DLT) for oil-water separation and moisture management, yet conventional pore-channel designs offer limited efficiency. Herein, we have developed a groundbreaking Janus nanofiber structure inspired by the structural characteristics of plant leaves, specifically the pore gradient and liquid transport channels within leaves. An innovative intermediate buffer layer composed of a three-dimensional helical nanofiber membrane was introduced to boost porosity and horizontal interconnectivity. A dopamine-controlled regulation mechanism synergistically optimized the pore structure and wettability of this layer. The resulting Janus membrane exhibits a remarkable unidirectional transport index (1250%), a high oil-water separation efficiency (98.92%), and an ultra-high flux (13860.77 L·m⁻²·h⁻¹). Its integration with textiles demonstrates superior moisture and thermal management, confirming its versatility for applications in oil-water separation, industrial wastewater treatment, and high-performance functional garments.

Quantitative Protein Labeling in Live Cells by Controlling the Redox State of Encoded Tetrazines The site-specific attachment of fluorophores, probes, or drugs to proteins in living systems is critical for advancing our understanding of biology and drug development. The site-specific encoding of 1,2,4,5-tetrazine (Tet) residues into target proteins provides the rapid kinetics and stability required for quantitative labeling in living cells, a property that is increasingly desirable as the resolution and specificity of imaging increases. Here, we adapt a common gel-shift assay to create a "PEG Chaser assay" for evaluating labeling completeness in living cells by "chasing" in-cell Tet reactions with an <i>in vitro</i> reaction with a TCO-PEG<sub>5000</sub> polymer; then, a gel shift distinguishes proteins that did not react in cells from those that did. We apply this to observe that encoded Tets exist in an equilibrium between oxidized (Tz) and reduced (DHTz) forms in living cells. We further show how a recently developed photooxidation treatment can convert the nonreactive DHTz Tet-protein to the reactive Tz form and enables its rapid, quantitative in-cell labeling. We then develop genetic code expansion machinery for encoding two new Tet ncAAs with different redox potentials and show how the tuning of the Tet redox is a useful variable for controlling the reactivity of Tet ncAAs. Specifically, the new Tet3H ncAA enables photoactivatable labeling and complete protein labeling in living cells in 5 min. This in-depth evaluation of the impact of the intracellular reducing environment on Tet reactivity and the demonstration of controlling Tet redox in living cells expands the utility of encodable Tet in living cells.

Influence of cellulose nanocrystal formulations on the properties of pregelatinized cornstarch and cornmint essential oil films More people are switching to biodegradable packaging, which is better for the environment and safer for food products. Meanwhile, edible films and coatings might be an option, they are easily degradable, safe for consumption, and environmentally friendly. This study aimed to evaluate the influence of various CNC formulations as Pickering emulsions with pregelatinized cornstarch incorporating essential oil of cornmint on the characterization of edible coating solutions and film. The development of edible films was using pregelatinized cornstarch (PCS), including cornmint essential oil (CEO) and cellulose nanocrystals (CNC). To examine the impact of the CNC content on the physicochemical, mechanical, and optical characteristics of these films, different concentrations (0.05, 0.07, 0.10, 0.25, 0.30, and 0.50% w/w) of CNC were added. The coating solution's pH and viscosity, as well as the thickness and roughness of the film, usually rise with an increase in CNC concentration. Conversely, this led to a reduction in the weight loss during heating, elongation, and tensile strength, as well as Young's modulus. The different amount of CNC (%) did not have a significant effect on the water solubility, hydrophobicity, color, water vapor permeability, or surface microstructure, as observed by atomic force microscopy. The addition of CNC to the film matrix reduced its mechanical strength but basically has low water vapor permeability and high surface hydrophobicity. Consequently, the films produced in this study can be effectively used as edible films in situations that demand strong resistance to water but do not require significant mechanical strength.
