Heavy metal pollution in water poses severe threats to ecosystems and human health, demanding urgent development of efficient and sustainable adsorbents. Herein, we report a novel amino-functionalized phenolic resin (APF) synthesized via a facile self-assembly strategy using 3-aminophenol and formaldehyde. This approach eliminates the need for toxic crosslinkers or complex post-modification steps, offering a green and scalable route for nanoscale polymer fabrication. The APF particles were engineered with controlled amino group density and hierarchical porosity through optimizing monomer ratios, achieving abundant active sites for multi-metal interactions. The APF adsorbent exhibits exceptional adsorption capacities for both cationic and anionic heavy metals, notably achieving 297.75 mg·g−1 for Cd2+ – surpassing conventional clay composites and rivaling advanced MOFs. Its multifunctional groups (–NH2, –OH) enable synergistic mechanisms: (1) electrostatic attraction for Cr6+ oxyanions at low pH, (2) chelation-dominated Cd2+ capture via amino coordination, and (3) ion exchange for Pb2+/As3+. This work advances the design of cost-effective, multi-mechanistic adsorbents for comprehensive heavy metal remediation.

The spread of cancer among human societies and the subsequent mortalities necessitates the development of intelligent cancer treatment methodologies with negligible side effects. Therefore, immunotherapy to cure victims with hematologic malignancies that have recently been approved, labeled as “chimeric antigen receptor (CAR) T-cell therapy”, was successfully developed with outstanding outcomes. However, CAR T-cell therapy still suffers from numerous safety challenges due to a lack of control over the location and exposure time of the anti-tumor immune effect and the prospective for off-target toxicity. This work aims to describe the design and development of light-switchable (liCAR) T-cells capable of precisely being activated for the real-time elimination of cancer cells. The development of intelligent targeting is accompanied by the emergence of the clustered, regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated protein 9 (Cas9) system. Notably, CRISPR-Cas9 allows multiplex genome editing, enabling the simultaneous targeting of multiple genomic loci. This capability has been successfully applied in cancer immunotherapy, for instance, to knock out multiple immune checkpoint regulators such as PD-1, CTLA-4, and LAG-3 in CAR T-cells, thereby improving their anti-tumor activity. Indeed, the gene therapy field has undergone a profound revolution thanks to this system. Consequently, it is crucial to guarantee that the CRISPR-Cas9 components are delivered efficaciously into the intricate three-dimensional (3D) structures of human retinal tissue to achieve successful gene editing. Nanoparticles (NPs) have been a critical component of recent technological advances in nanomedicine, enabling CRISPR-Cas9 to deliver its therapeutic agents with high efficiency, substantially improving its therapeutic potential. The significant progress in NP technology has resulted in the emergence of novel opportunities for gene therapy, therefore presenting a very encouraging approach for addressing illnesses and disorders by targeting the genetic level. Overall, this review focuses on smart cancer immunotherapy techniques by providing a combined perspective of nanotechnology and genome editing by considering the challenges and gaps in this field.

In this study, a series of ceria-doped cobalt-based composites were synthesized via the incorporation of cobalt and cerium precursors into trimesic acid-based metal–organic frameworks (MOFs), followed by pyrolysis to obtain Co–CeO2/C hybrid materials. The thermal decomposition of the MOF structure facilitated the in-situ formation of a conductive carbon matrix comprising carbon nanotubes (CNTs) and carbon nanospheres, catalyzed by cobalt nanoparticles. Among the prepared composites, the 5Co-5Ce/C sample exhibited the most promising electrochemical performance, delivering a high specific capacitance of 839F g−1 at a current density of 0.1 A g−1 and demonstrating excellent cycling stability, with 97% capacitance retention after 6000 charge- discharge cycles at 10 A g−1. The superior performance is attributed to the synergistic effect between cobalt and cerium oxide, wherein CeO2 not only enhances faradic charge storage through reversible redox reactions but also promotes the development of a mesoporous structure. Cerium was found to influence the crystallization behavior of cobalt during pyrolysis, thereby regulating the growth and distribution of CNTs and nanospheres. This structural refinement contributes to an increased electrochemically active surface area and improved ion transport kinetics, leading to enhanced overall capacitive behavior. These results highlight the potential of Co–CeO2/C composites as promising electrode materials for high-performance supercapacitor applications.
本研究通过将钴和铈前驱体掺入三羧酸基金属有机骨架（mof）中，合成了一系列掺杂铈的钴基复合材料，然后热解得到Co-CeO2 /C杂化材料。MOF结构的热分解促进了由碳纳米管（CNTs）和碳纳米球组成的导电碳基体的原位形成，并由钴纳米颗粒催化。在制备的复合材料中，5Co-5Ce/C样品表现出最有希望的电化学性能，在0.1 a g−1电流密度下提供839F g−1的高比电容，并表现出优异的循环稳定性，在10 a g−1充放电循环6000次后电容保持率为97%。优异的性能归功于钴和氧化铈之间的协同作用，其中CeO2不仅通过可逆氧化还原反应增强了faradic电荷存储，而且促进了介孔结构的发展。发现铈在热解过程中影响钴的结晶行为，从而调节CNTs和纳米球的生长和分布。这种结构的改进有助于增加电化学活性表面积和改善离子传输动力学，从而增强整体电容行为。这些结果突出了Co-CeO2 /C复合材料作为高性能超级电容器电极材料的潜力。

The activation mechanism of peroxymonosulfate (PMS) has been thoroughly investigated using homogeneous and heterogeneous catalysts. However, research on catalyst-free systems was still in its early stages. In this study, the removal efficiency of unactivated PMS and its chloride salt (Cl−/PMS) in the treat of organic pollutants in a catalyst-free system was systematically examined. Results showed that 93.1% of diclofenac (DCF) was degraded in the Cl-/PMS system, and the mechanism was mainly attributed to the synergistic oxidation of reactive oxygen species and reactive chlorine species (Cl• and HClO). It was noted that ClO• quenching could be effectively inhibited in an acidic environment, resulting in a significantly improved removal rate of pollutants. It examined the contribution rates of various reactive species in the degradation of pollutants. The TOC removal rate of DCF within 30 min is 48.61%. The intermediate were identified based on LC-MS analysis, and their transformation pathways were found to primarily including hydroxylation, amine oxidation, decarboxylation, and demethylation. The ecotoxicity of degradation intermediates was reduced, according to the ECOSAR model. Comparative experiments elucidated the degradation efficiency, kinetics, and mechanisms of pollutants in the Cl-/PMS system, providing a new theoretical basis for PMS activation in a catalyst-free, background anion system.

Metal-organic frameworks (MOFs) are renowned for their crystalline porosity and structural versatility, but their limitations in aqueous stability and handling have historically curtailed practical applications. To address these challenges, MOFs are transformed into carbonaceous derivatives (carbon-MOFs), which offer enhanced stability, surface functionality, and chemical/thermal resilience. This review provides a comprehensive overview of synthetic strategies for carbon-MOF composites and explores their applications in environmental remediation. Beyond conventional catalytic and adsorption roles, we spotlight groundbreaking advancements in carbon-MOF engineering, including defect-engineered architectures that amplify active sites and stability, magnetic composites enabling facile recyclability, and hybrid membranes for precision separation. Recent strides in machine learning-guided design further accelerate the discovery of tailored carbon-MOFs with optimized porosity and multifunctionality. We critically assess their catalytic performance in dye degradation, heavy metal removal, and CO2 capture/conversion, emphasizing how these innovations overcome traditional limitations. Integrating carbon-MOFs into membrane technology and defect modulation strategies highlights their scalability for real-world water/air purification systems. Emerging trends such as bioinspired designs, multi-pollutant adaptability, and green synthesis routes are also discussed, positioning carbon-MOFs as versatile platforms for next-generation environmental technologies. By bridging structural innovation with functional versatility, this review underscores carbon-MOFs’ potential to drive sustainable solutions in pollution remediation applications.

Addressing the critical instability of LiNiO2 (LNO) cathodes is paramount for advancing high-energy batteries. This study presents a significant advancement by demonstrating the crucial role of synthesis strategy in hafnium (Hf) doping efficacy. Our novel contribution lies in the direct, multi-technique comparison of coprecipitation versus solid-state methods, revealing that only coprecipitation facilitates the essential homogeneous bulk Hf integration required for effective stabilization. Comprehensive characterization provides compelling evidence that this bulk doping dramatically suppresses H2–H3 phase transitions and Ni migration, unlike the less effective surface-dominant doping via solid-state reaction. The significance is demonstrated by the markedly superior cycling stability and sustained Li-ion diffusion kinetics of coprecipitated Hf-doped LNO. This work fundamentally highlights the necessity of achieving bulk dopant integration through optimized synthesis, offering a vital blueprint for developing robust, next-generation Ni-rich cathode materials.

In this work, the phosphoric acid activated foams from spontaneous combustion coal gangue were successfully fabricated using a simple and fast one-step microwave-assisted method. The physico-mechanical, thermal insulation properties, and microstructure of foam specimens prepared with varying molar concentrations of the activating solution (10–14 M), liquid-to-solid (L/S) ratios (0.425–0.525), microwave power (600–1000 W), microwave irradiation time (7.5–12.5 min), and post-curing temperatures (25–115 °C) were investigated. X-ray microfocus computed tomography (micro CT) and scanning electron microscopy (SEM) results showed that the homogeneous porous structure of the foam specimens was developed at higher H3PO4 concentrations when using 1000 W power of the microwave oven for 10 min. The optimized phosphoric acid-activated foams from spontaneous combustion CG exhibit a thermal conductivity of 0.133 W/mK and an unconfined compressive strength of 10.2 MPa, making them comparable to or better than traditional foam materials derived from CG. The obtained results contribute to further advancing the application of phosphoric acid activated CG foams in the fields of building thermal insulation and other lightweight high-temperature insulating materials.

Graphitic carbon nitride (g-C3N4, CN) is widely regarded as a promising non-metallic photocatalyst due to its low cost, facile synthesis, and excellent thermal and chemical stability. However, bulk g-C3N4 (BCN) suffers from low surface area, limited charge carrier mobility, and fast recombination of photogenerated electron–hole pairs, severely restricting its CO2 photoreduction performance. Although numerous synthesis and modification strategies have been proposed, existing reviews often lack timeliness, in-depth mechanistic analysis, and comprehensive outlooks on future directions. This review provides an updated summary of recent progress in g-C3N4-based photocatalysts. Six typical preparation strategies are introduced, with discussions on their advantages, limitations, and innovations. The impact of modifications on kinetics, thermodynamics, and structure–performance relationships is analyzed. Synergistic effects among strategies are also emphasized. Furthermore, three promising modification strategies are proposed, accompanied by targeted recommendations. Finally, four future directions are outlined: (i) development of green and sustainable photocatalysts, (ii) application of machine learning (ML) in catalyst design, (iii) improved selectivity for long-chain hydrocarbon fuels, and (iv) design of broadband photocatalysts. Special attention is given to the role of ML and theoretical calculations in enabling rational catalyst design.

Due to population growth and rising living standards, municipal solid waste (MSW) generation is increasing, presenting significant environmental and sustainability challenges. While waste-to-energy (WtE) technologies have been widely studied as an alternative to conventional landfilling, existing literature primarily focuses on technological advancements in WtE processes or waste segregation challenges in isolation. However, a comprehensive evaluation of how segregation inefficiencies directly impact WtE performance and circular economy strategies remains largely unexplored. This review bridges this gap by analyzing technical and policy-related barriers to efficient MSW management. We provide a comparative assessment of thermochemical (incineration, pyrolysis, gasification) and biochemical (anaerobic digestion, composting) WtE technologies, identifying the optimal pathways based on waste composition and their economic feasibility. Additionally, this study explores the role of regulatory frameworks and circular economy principles in enhancing waste recovery and sustainable energy production. Our findings emphasize that improved waste segregation, advanced preprocessing, and policy-driven interventions are essential for maximizing WtE efficiency and reducing greenhouse gas emissions. By integrating technological insights, economic considerations, and policy recommendations, this review provides a comprehensive perspective that may help researchers, policymakers, and industry stakeholders in optimizing MSW treatment for a sustainable future.

Due to improper disposal and mismanagement of plastic waste, plastic converted into microplastic when exposed to the environment causes tremendous burdens to nature. It becomes the most persistent pollutant in air, water, and land environments due to the inert property of plastic. It enters the environment from various sources, such as industrial, household, and agricultural waste, affecting the lives of humans, other living beings, and the entire ecosystem. Much research and experimentation have been conducted to eliminate microplastics from the environment with the help of conventional methods, such as physical, chemical, and biological, which remove microplastics but are inefficient in eliminating them from the environment. Some processes are good for nature and the environment, as they can cause secondary pollution. Therefore, there is a need for some scientifically proven new methods to achieve the required level of results and be environmentally friendly. Bioremediation is a sound technique used to degrade plastic with the help of bacteria, fungi, algae, and insects. However, some studies reveal that the pretreatment (UV, thermal, chemical, and physical) can change the inert property of plastic, making it more available to the microbes and increasing the biodegradation process without affecting the microbes’ life. Such a treatment gives hope for removing plastic from the environment in an efficient way.
