The integration of Generative Artificial Intelligence (GenAI) intouniversity-level academic writing presents both opportunities and challenges,particularly in relation to cognitive dissonance (CD). This work explores howGenAI serves as both a trigger and amplifier of CD, as students navigateethical concerns, academic integrity, and self-efficacy in their writingpractices. By synthesizing empirical evidence and theoretical insights, weintroduce a hypothetical construct of GenAI-induced CD, illustrating thepsychological tension between AI-driven efficiency and the principles oforiginality, effort, and intellectual ownership. We further discuss strategiesto mitigate this dissonance, including reflective pedagogy, AI literacyprograms, transparency in GenAI use, and discipline-specific task *** approaches reinforce critical engagement with AI, fostering a balancedperspective that integrates technological advancements while safeguarding humancreativity and learning. Our findings contribute to ongoing discussions on AIin education, self-regulated learning, and ethical AI use, offering aconceptual framework for institutions to develop guidelines that align AIadoption with academic values. © 2025, CC BY.

Silicon (Si) holds immense promise as viable anode for next-generation high-energy-density Li-ion batteries (LIBs). However, its poor ionic/electronic conductivity and significant volumetric changes during cycling lead to rapidly deteriorated LIB performance. Here, a novel multifunctional coating featuring ultrafine SiO2 nanoparticles (2-C) to resolve these challenges is proposed. This unique uSiO2-C coating provides high-efficient electron and ion transport pathways, while also improves interfacial stability and mitigates volume changes during cycling, thereby enhancing the conductivity and structural integrity of Si@uSiO2-C, as corroborated by extensive experimental and computational studies. In addition, the abundant interfaces in uSiO2-C coating facilitate Li+ transport and the evenly distributed ultrafine SiO2 nanoparticles impart high electrochemical reactivity and mechanical robustness. Consequently, the Si@uSiO2-C anode achieves a high reversible capacity of 2093 mAh g−1 at 0.2 A g−1, with a high initial Coulombic efficiency of 88.3%, superior rate capability and durability (1000 cycles, 928 mAh g−1 at 1.0 A g−1, 75% capacity retention). Full cells paired with commercial LiFePO4 cathodes demonstrate high cyclability, maintaining 80% capacity retention over 500 cycles at 4 C. This work highlights the vital role of multifunctional coating in promoting the electrochemical performance of Si-based anodes for high-performance LIBs. © 2025 Wiley-VCH GmbH.

Hierarchically Porous Carbon Membranes Derived from PAN and Their Selective Adsorption of Organic Dyes

引用

Chinese Journal of Polymer science 2016年第1期34卷 23-33页

Porous carbon membranes were favorably fabricated through the pyrolysis of polyacrylonitrile（PAN） precursors, which were prepared with a template-free technique-thermally induced phase separation. These carbon membranes possess hierarchical pores, including cellular macropores across the whole membranes and much small pores in the matrix as well as on the pore walls. Nitrogen adsorption indicates micropores（1.47 and 1.84 nm） and mesopores（2.21 nm） exist inside the carbon membranes, resulting in their specific surface area as large as 1062 m2/g. The carbon membranes were used to adsorb organic dyes（methyl orange, Congo red, and rhodamine B） from aqueous solutions based on their advantages of hierarchical pore structures and large specific surface area. It is particularly noteworthy that the membranes present a selective adsorption towards methyl orange, whose molecular size（1.2 nm） is smaller than those of Congo red（2.3 nm） and rhodamine B（1.8 nm）. This attractive result can be attributed to the steric structure matching between the molecular size and the pore size, rather than electrostatic attraction. Furthermore, the used carbon membranes can be easily regenerated by hydrochloric acid, and their recovery adsorption ratio maintains above 90% even in the third cycle. This work may provide a new route for carbon-based adsorbents with hierarchical pores via a template-free approach, which could be promisingly applied to selectively remove dye contaminants in aqueous effluents.

Glioma is a highly lethal tumor with a poor prognosis, in which the presence of the blood-brain barrier (BBB) and skull significantly limits treatment options. To address this, a tumor-implantable optofluidic system (LED-SC), consisting of a microsized LED (microLED) and a microsyringe chip (SC), is proposed to deliver both light and prodrug nanoparticles (PNPs) directly to brain glioma. The LED-SC combines microLED and SC to enable intratumoral administration of light and PNPs for chemophotodynamic therapy. PNPs, self-assembled nanoparticles of verteporfin (VPF)-doxorubicin (DOX) prodrug, are cleaved by the enzyme cathepsin B, releasing active drugs specifically within tumor cells. In vitro studies show that PNPs are taken up by glioma cells and exhibit enhanced cytotoxicity under light irradiation. The PNPs-loaded LED-SC can be implanted into glioma, wherein PNPs are slowly diffused through the tumor, bypassing the BBB, and it also ensures effective light delivery in glioma beneath the skull, boosting chemo-photodynamic therapy. In glioma mouse models, PNP-loaded LED-SC implantation showed a 3.9-fold improvement in PNP delivery efficiency over intravenous administration, leading to better drug distribution and therapeutic results. The PNPs-loaded LED-SC offers a promising and minimally invasive solution for glioma treatment, overcoming the barriers of the BBB and skull while reducing systemic toxicity. © 2025 American chemical Society.

Journal of Cleaner Production 2025年 511卷

Rahim, Md Arifur Malik, Zainab Rahman, Ataur School of Engineering Design and Built Environment Western Sydney University NSW2751 Australia Climate Change Research Centre The University of New South Wales NSW2052 Australia Climate System Hub National Environmental Science Program Australian Government Australia Department of Chemical and Biological Engineering Monash University ClaytonVIC3800 Australia

This study investigates the progress in using nanomaterials in reflective coating (RC) technology. Generally, the benefits of RC are twofold: minimizing surface temperature and protecting surfaces. The purpose of applying RC is versatile, such as lowering the urban heat island effect and building energy consumption, improving photovoltaic performance, and increasing the durability of infrastructure. Incorporating nanomaterials in RC mixes enhances the effectiveness of this technology. However, the technical feasibility and economic viability of an appropriate preparation procedure with a proper mix design remain debatable. This review looks into peer-reviewed research articles related to the application of nanomaterials in RC technology in the core "Web of science" and "Scopus" collections. It can be argued that researchers used nanomaterials for five distinct purposes: a) blocking near-infrared and ultraviolet portions of solar radiation, b) temperature shielding, c) radiative cooling, d) sub-ambient cooling, and e) surface cleaning or self-cleaning. It is revealed that nanomaterials could enhance the surface solar reflectivity and emissivity to 97 % and 0.97, respectively. The reported surface temperature reduction ranges between 2 and 35 °C with a statistical median value of 9.6 °C, whereas the sub-ambient cooling ranges between 2 and 13 °C with a statistical median value of 5 °C. Cooling power of the RC ranged between 35 and 135 W/m2, with a median value of 77 W/m2. Inconsistencies in RC performance have been discussed in the related sections. It is also found that a superhydrophobic RC can be prepared with a contact angle of ∼164°, but the coating has its advantages and limitations. The role of nanomaterials in enhancing UV stability and durability is discussed, along with the practicality and scalability of the technology. It is revealed that key challenges in RC technology include economic viability, stability concerns, and environmental implications. Based o

This study presents an innovative approach integrating ultrasound-assisted extraction (UAE) with ionic gelation encapsulation and freeze-drying to optimize the recovery and delivery of bioactive compounds from black mulberry leaves. UAE, under optimized conditions (60 °C, 2.5 min, 20% amplitude), increased the concentration of chlorogenic acid by 2.47 times compared to conventional methods (2.38 ± 0.11 g/100 g), producing extracts with high phenolic content (168.17 mg GAE/g) and strong antioxidant activity (1076.46 µMol TE/g, DPPH). The encapsulation process achieved 73.88% efficiency, retaining 72-87% of total phenolics and antioxidant activity in DPPH, FRAP, and ABTS assays. Encapsulated compounds showed thermal stability up to 200 °C, confirmed by thermogravimetric analysis, and high bioaccessibility (84.61 ± 0.89%) in *in vitro* digestion tests. This approach highlights the synergy between sustainable extraction and encapsulation, with sodium alginate offering an ecologically friendly method to protect bioactives and ensure controlled release. © 2025, The Authors.

Five novel near-infrared electrochromic aromatic polyimides （PIs） with pendent benzimidazole group were synthesized from 4,4＇-diamino-4＂-（1-benzylbenzimidazol-2-yl）triphenylamine （named as DBBT） with five different dianhydrides via two-step polymerization process, respectively. The maximum UV-Vis absorption bands of these PIs locate at about 335 nm for solid films due to the π-π＊ transitions. A reversible pair of distinct redox peaks, that were associated with a noticeable color change from original yellow to blue, was observed in the cyclic voltammetry （CV） test. A new absorption peak emerged at 847 nm in near-infrared （NIR） region with increasing voltage in UV-Vis-NIR spectrum, which indicates that PI can be used as NIR electrochromic material. These novel PIs have good electrochemical stability, appropriate energy levels for the highest occupied molecular orbital （HOMO） and the lowest unoccupied molecular orbital （LUMO）, in the range of-5.17 eV to -5.20 eV and -2.14 eV to -2.26 eV （versus the vacuum level） determined by cyclic voltammetry method. These values basically consisted with the results of quantum chemical calculation. These polyimides can be used as novel electrochromic and hole transportation materials.

In this work, the electroreduction of carbon dioxide (CO₂) to oxalate is enabled by incorporating trace metallic lead (Pb) on carbon-based supports (CBS) with polymer overlayers. These composite materials serve as an efficient electrocatalytic system for the facile conversion and storage of CO₂, a pernicious atmospheric pollutant. Results from controlled potential electrolysis experiments indicate that 1) trace metallic Pb on the ppb scale is active toward the reductive coupling of CO₂ to oxalate at comparable Faradaic efficiencies to bulk metallic Pb and 2) polymer encapsulation of this trace metallic Pb leads to promotion of CO₂ reduction (CO₂R) selectively to metal oxalates over other products such as CO. Importantly, metal oxalates are important alternative cementitious materials and precursors for other materials’ synthesis applications. The solid products undergo rigorous spectroscopic characterization, including ¹³CO₂ labeling experiments, to ensure the metal oxalates are in fact produced from CO₂R. These findings serve as a model for leveraging microenvironment effects to enhance activity and selectivity for CO₂R using trace-metal catalysts for carbon utilization and storage technologies. © 2025 The Author(s).

The synthesis of block copolymers of poly(tetrahydrofuran)-b-poly(α-amino acid)(PTHF-b-PAA)is challenging since it is difficult to combine the two blocks produced via different/conflicting ring-opening polymerization(ROP)*** this contribution,the cationic ROP of THF is catalyzed by rare-earth triflate[RE(OTf)3]and terminated by 2-(t-butyloxycarbonyl-amino)ethanol(BAE).After the deprotection of t-butyloxycarbonyl(Boc)group,the chain end of PTHF is quantitatively changed to amino group which thereafter initiates the nucleophilic ROP ofα-amino acid N-thiocarboxyanhydrides(NTAs).Both polymerizations are well controlled,generating PTHF and PAA segments with designable molecular weights(MWs).PTHF-b-polylysine(PTHF-b-PLys)and PTHF-b-polysarcosine(PTHF-b-PSar)are obtained with MWs between 8.6 and 28.7 kg/*** above amphiphilic diblock copolymers form micelles in ***40-b-PSar32 acts as a surfactant to stabilize oil-in-water *** segments of PTHF-b-PAA are biocompatible and promising in the biomedical application.

Probabilistic genotype-phenotype maps reveal mutational robustness of RNA folding, spin glasses, and quantum circuits

Physical Review Research 2025年第1期7卷 013118-013118页

作者： Anna Sappington Vaibhav Mohanty Department of Electrical Engineering and Computer Science Massachusetts Institute of Technology Cambridge Massachusetts 02139 USA Harvard-MIT Program in Health Sciences and Technology Harvard Medical School Boston Massachusetts 02115 USA and Massachusetts Institute of Technology Cambridge Massachusetts 02139 USA Harvard/MIT MD-PhD Program Harvard Medical School Boston Massachusetts 02115 USA and Massachusetts Institute of Technology Cambridge Massachusetts 02139 USA Department of Chemistry and Chemical Biology Harvard University Cambridge Massachusetts 02138 USA

Recent studies of genotype-phenotype maps have reported universally enhanced phenotypic robustness to genotype mutations, a feature essential to evolution. Virtually all of these studies make a simplifying assumption that each genotype—represented as a sequence—maps deterministically to a single phenotype, such as a discrete structure. Here we introduce probabilistic genotype-phenotype (PrGP) maps, where each genotype maps to a vector of phenotype probabilities, as a more realistic and universal language for investigating robustness in a variety of physical, biological, and computational systems. We study three model systems to show that PrGP maps offer a generalized framework which can handle uncertainty emerging from various physical sources: (1) thermal fluctuation in RNA folding, (2) external field disorder in the spin-glass ground state search problem, and (3) superposition and entanglement in quantum circuits, which are realized experimentally on IBM quantum computers. In all three cases, we observe a biphasic robustness scaling which is enhanced relative to random expectation for more frequent phenotypes and approaches random expectation for less frequent phenotypes. We derive an analytical theory for the behavior of PrGP robustness, and we demonstrate that the theory is highly predictive of empirical robustness.
