Unveiling the effects of thermodynamic interaction of basalt fibers/epoxy interfaces on thermal stability, mechanical properties and corrosion resistance of basalt fibers reinforced waterborne epoxy coatings Abstract In this study, the interfacial interaction between the 3‐aminopropyltriethoxysilane (APTES) modified basalt fibers (BF@A x ) and waterborne epoxy was studied by using thermodynamic approaches and creating a “wetting‐reagglomeration‐adsorption” isocontour map of waterborne epoxy. Combined with the TG‐DSC, dynamic thermomechanical analysis (DMA), tensile, flexural, electrochemical impedance spectrum (EIS) and salt spray tests, the enhancement effects of interfacial interaction on thermal stability, mechanical properties and corrosion resistance were demonstrated. From the isocontour map, APTES modification reduces the surface energies of BF@A x fillers from 53.05 to 50.27 mJ/m 2 , which results in the driving energy for reagglomeration decreasing from 17.04 to 10.41 mJ/m 2 and the adsorption energy increasing from 20.24 to 20.77 mJ/m 2 , suggesting that the BF fillers' dispersion performance and interfacial strengths of BF composite coatings are enhanced. Compared to the varnish coating, the tensile and flexural strengths of the epoxy (EP)/BF@A 9.5 coating are increased by 55.87% and 36.36%, respectively, and the thermal stability is enhanced, due to the BF@A 9.5 fillers' optimal dispersion. Meanwhile, EP/BF@A 5.0 coating has the best corrosion resistance with | Z | 0.01Hz value above 10 9 Ω cm 2 after 35 days and salt spray resistance exceeding 120 days. This work provides a new insight into how the interfacial interaction between the one‐dimensional rod fillers and matrices affects the composites' properties from the thermodynamics. Highlights Waterborne epoxy coatings were reinforced by the modified chopped BFs. Impact of APTES modification on the BF surface energy was uncovered. Interaction of BFs/epoxy interfaces was studied by thermodynamic approaches. Effect of interfacial interaction on properties of coatings was unveiled.

Effect of the AlGaO Spacer Layer on the Performance of β‐Gallium Oxide Metal–Oxide Semiconductor Field Effect Transistors Abstract This study utilizes a metalorganic chemical vapor deposition system to grow a β‐Ga 2 O 3 epitaxial layer on a sapphire substrate and fabricate lateral β‐Ga 2 O 3 metal‐oxide‐semiconductor field‐effect transistors (MOSFETs). To enhance the performance of the β‐Ga 2 O 3 MOSFET, a (Al x Ga 1‐x ) 2 O 3 spacer layer is introduced, with its aluminum (Al) composition modulated through energy band engineering. Three epitaxial samples are designed: a reference sample (without a spacer layer) and samples with (Al x Ga 1‐x ) 2 O 3 layers containing different Al compositions, specifically (Al 0.14 Ga 0.86 ) 2 O 3 and (Al 0.21 Ga 0.79 ) 2 O 3 . The influence of the Al composition in the (Al x Ga 1‐x ) 2 O 3 layer on the two dimensional electron gas (2DEG) is investigated. The results show that a lower Al composition increases the carrier concentration in the 2DEG, boosting the saturation current (I D,sat ) from 2.94 to 7.88 mA mm −1 —a significant 168% improvement in the (Al x Ga 1‐x ) 2 O 3 /β‐Ga 2 O 3 stacked epitaxy structure. For the high‐Al‐composition barrier layer ((Al 0.21 Ga 0.79 ) 2 O 3 ), the higher energy barrier slightly reduces the turn‐on current but effectively increases the breakdown voltage, from 210 to 576 V—an improvement of 188%. These improvements result from the higher energy barrier of the β‐Ga 2 O 3 /(Al x Ga 1‐x ) 2 O 3 interface, which reduced the leakage current density. By optimizing the Al composition in (Al x Ga 1‐x ) 2 O 3 , transistors suitable for either high performance or high breakdown voltage are successfully produced.

Poly-L-lactic acid nanofiber/polyamidoamine composite hydrogel as novel strategy for in vitro neuroregeneration and neuroprotection A purposely designed PLLA/H-AGMA<sub>20</sub> composite hydrogel incorporating an electrospun poly-L-lactic acid (PLLA) mat in a cell-adhesive polyamidoamine hydrogel (H-AGMA<sub>20</sub>) was investigated as a novel biomaterial with neuroregenerative and neuroprotective properties. A PLLA mat was first functionalized by exposure to ethylenediamine vapors, introducing amine functions through ester group aminolysis, and then impregnated with an α,ω-acrylamide-terminated oligomer (AGMA<sub>20</sub>) aqueous solution. The system was finally cured through UV-induced radical polymerization. The resulting H-AGMA<sub>20</sub> matrix was covalently grafted onto the PLLA nanofibers since a portion of the AGMA<sub>20</sub> acrylamide terminals reacted with their surface amine groups, leading to the soft and pliable PLLA/H-AGMA<sub>20</sub> composite. Biological investigations performed on preneuronal and immune cell lines demonstrated that PLLA/H-AGMA<sub>20</sub> exhibits promising neuroregenerative properties, effectively promoting both cell proliferation and neuronal differentiation. In addition, the composite demonstrated significant neuroprotective effects in vitro, counteracting neurotoxin 1-methyl-4-phenylpyridinium (MPP<sup>+</sup>) and proinflammatory agent lipopolysaccharide (LPS)-induced cytotoxicity. These protective results appear to be mediated by modulation of inflammatory pathways, highlighting the combined capacity of biomaterial to support neuronal development while reducing neuroinflammatory damage.

Modulating Oxide‐Based Quantum Materials by Ion Implantation Abstract Ion implantation has emerged as a powerful tool for manipulating and investigating oxide quantum materials, where strong electron correlations give rise to exotic phases and functionalities. This Review examines how controlled ion bombardment enables targeted modulation of structural, electronic, and magnetic properties in complex oxides. Recent advances in ion beam techniques is analyzed that provide unprecedented control over defect profiles, from point defects to extended damage cascades. In application, ion irradiation has demonstrated the ability to tune quantum phenomena including metal‐insulator transitions, magnetism, and superconductivity through selective doping, defect creation, and lattice strain. The ability to write quantum states with nanoscale precision using focused ion beams is opening new paths for quantum device fabrication. Challenges in understanding radiation damage mechanisms in strongly correlated systems is discussed, and identify opportunities for designing quantum functionality through defect‐engineering approaches. The technique's demonstrated capability to write quantum states with nanoscale precision, combined with its compatibility with existing semiconductor processing infrastructure, suggests a clear pathway for translating fundamental discoveries in quantum materials into practical technological applications.

Isolation and Identification of Xylose-Utilising, Polyhydroxyalkanoate-Producing Bacteria from Sugarcane Bagasse: First Report of PHA Production by Mycolicibacterium Smegmatis Abstract Polyhydroxyalkanoates (PHAs) are biodegradable polyesters that are considered as alternatives to petroleum derived plastics. To reduce the production cost, many studies have focused on the use of sugarcane bagasse (SCB) as a cheap substrate for the biosynthesis of PHAs. Many microorganisms have been reported as PHA producers, but only a few can utilise xylose as a carbon source for their production. In this study, five xylose-utilising PHA producing bacteria (two mesophilic and three thermophilic) were isolated from decomposing SCB and assessed. Among the five isolates, Mycolicibacterium smegmatis , reported for the first time as a PHA producer, accumulated the highest amount of PHA using xylose (22% cell dry weight). M. smegmatis was then tested for its ability to utilise a mixture of simple sugars (2 glucose: 1 xylose) and alkaline pretreated SCB hydrolysate without any detoxification step. The results showed bacterial growth in both media; however, growth was lower in the media supplied with the hydrolysate (0.63 g L −1 ) compared with a mixture of glucose and xylose (1.11 g L −1 ), presumably due to the presence of inhibitors in the hydrolysate. PHA accumulation was similar in media supplied with hydrolysate or mixture, with 27% and 28% cell dry weight, respectively. The extracted biopolymer was studied by Fourier Transform Infrared (FTIR) spectroscopy, Gas Chromatography Mass Spectrometry (GC-MS) and Scanning Electron Microscopy (SEM) and identified as polyhydroxybutyrate (PHB). These findings highlighted the potential use of M. smegmatis for PHB production after further optimisation steps.

Chitosan-Based Drug Delivery Systems for Targeted Chemotherapy in Colorectal Cancer: A Scoping Review Chitosan (CS) has emerged as a versatile biopolymer for designing drug delivery systems (DDS) in colorectal cancer (CRC) therapy due to its biocompatibility, mucoadhesive properties, and ability to be surface-functionalized. This scoping review systematically analyzed current experimental studies on CS-based DDS for CRC, comparing non-targeted formulations with ligand-modified systems to identify advances in targeting efficiency, drug release behavior, and biological outcomes. Among the twenty-five initially identified studies, divided into two categories, non-targeted CS-based DDSs and ligand-modified CS-DDSs, five fulfilled the inclusion criteria for ligand-functionalized systems. These incorporated targeting moieties, such as folic acid (FA), hyaluronic acid (HA), and galactose (Gal), to achieve receptor-mediated uptake via FRα, CD44, and ASGP receptors, respectively. Ligand modification consistently enhanced cellular uptake, reduced IC<sub>50</sub> values, and improved tumor-selective cytotoxicity compared to non-targeted systems. However, in vivo validation remains scarce, with only one study confirming tumor accumulation in xenograft models. Moreover, no clinical trials currently assess CS-based nanocarriers for the treatment of CRC. Overall, CS represents a promising modular platform for targeted nanomedicine, but translational progress requires bridging preclinical success with comprehensive in vivo and clinical evaluation.

Environmental Life Cycle Assessment of Poly(3-hydroxybutyrate) (PHB): A Comparative Study with Petrochemical and Bio-Based Polymers In the context of the urgent global transition toward sustainable materials, this study presents a comparative environmental life cycle assessment (LCA) of poly(3-hydroxybutyrate) (PHB), a biodegradable, bio-based polymer, against conventional petrochemical plastics (polystyrene—PS; polypropylene—PP) and another popular biopolymer, namely polylactic acid (PLA). The LCA was conducted using primary production data from a laboratory-scale PHB manufacturing process, integrating real-time energy consumption measurements across all production stages. Environmental indicators such as carbon footprint and energy demand were analyzed under cradle-to-gate and end-of-life scenarios. The results indicate that PHB, while offering biodegradability and renewable sourcing, currently exhibits a significantly higher carbon footprint than PP, PS, and PLA, primarily due to its energy-intensive downstream processing. However, the environmental impact of PHB can be markedly reduced—by over 67%—through partial integration of renewable energy. PLA demonstrated the lowest production-phase emissions, while PP showed the most favorable end-of-life outcomes under municipal waste management assumptions. The study highlights the critical influence of energy sourcing, production scale, and waste treatment infrastructure on the sustainability performance of biopolymers. These findings provide practical insights for industry and policymakers aiming to reduce the environmental burden of plastics and support a shift toward circular material systems.
