Published: August 2024

AbstractIn the realm of intelligent cockpits, the predominant emphasis on enhancing driving safety and comfort through human‐vehicle interaction and driving behavior monitoring has conventionally centered on the upper body of the driver. Regrettably, the wealth of information inherent in the lower half of the driver's body, particularly the feet, tends to be systematically underestimated by researchers. A specialized intelligent carpet tailored for automotive cockpits that integrates sponge‐based triboelectric sensor to monitor driver's foot movement is proposed. The intelligent carpet contains two areas, namely the human‐vehicle interaction sensing area and the driving intention monitoring area. With the human‐vehicle interaction sensing area, the driver can interact with the vehicle through the left foot, resulting in reducing the occupation of visual resources and hand load. Furthermore, the driving intention monitoring area supported by the right foot can effectively identify driver's intentions and driver's behaviors, which are essential to trajectory prediction, optimal path planning, and driving safety. It is demonstrated that an intelligent carpet is potentially useful for human‐vehicle interaction, and transportation optimization and accident prevention.

AbstractRecently emerging perovskite nanocrystals (PNCs) have drawn considerable attention due to the superior optoelectronic performances. However, the terrible stability of red emissive PNCs (r‐PNCs) limits their broader application in aqueous media. Despite various encapsulation methods are proposed, the preparation of aqueous r‐PNCs with facile operation and excellent durability is still challenging. Herein, aqueous green emissive PNCs (g‐PNCs) by employing water as an external stimulus to treat oleyamine‐capped CsPbBr3 PNCs are synthesized initially, and then aqueous‐stable pure red emissive PNCs by anion‐exchange reaction and subsequently thiocyanate (SCN‐) passivation treatment (SCN‐r‐PNCs) are prepared. The obtained aqueous‐stable SCN‐r‐PNCs display high brightness, outstanding stability, and extended photoluminescence lifetime. Moreover, by combining aqueous r‐PNCs and portable smartphones, a fluorescence chemosensor for the detection of aqueous SCN− ions is constructed, which exhibits simple operation, high sensitivity, high selectivity, low detection limit, and visualized sensing. This work not only provides a new and facile strategy to prepare aqueous‐stable red emissive PNCs, but also further extends the application of red emissive PNCs in aqueous‐based fields.

Published: August 2024

AbstractThe quest for high‐performance energetic materials for defense and aerospace has intensified, focusing on balancing energy output and safety. This study presents the synthesis of 3D energetic metal‐organic frameworks (EMOFs) [Na3(DNT)(H2O)]n (Na‐MOF), [K2(DNT)2(H2O)]n (K‐MOF), and [Cs2(DNT)]n (Cs‐MOF) using 1,2,4‐dinitrimino triazole (DNT) through a hydrothermal process. The synthesized EMOFs are characterized using infrared spectroscopy, powder X‐ray diffraction, scanning electron microscopy (SEM), elemental analysis, and thermogravimetric analysis and differential scanning calorimetry, and structures confirmed via single‐crystal X‐ray diffraction, revealing 3D frameworks with crystal densities of 2.15, 2.16, and 2.86 g cm−3, respectively. Among them, Na‐MOF exhibits excellent detonation performance (VOD = 8900 m s−1, DP = 26.21 GPa), high thermal stability (Td = 369 °C), and insensitivity to impact and friction (IS = 40 J, FS = 360 N). K‐MOF displays balanced energetic and mechanical properties, while Cs‐MOF, though moderate in energetic performance, shows significant potential in pyrotechnic applications, producing a bright red flame. Intermolecular interactions are analyzed through Hirshfeld surface, 2D fingerprint, and SEM analyses, enhancing the understanding of particle size and morphology. Na‐MOF also demonstrates high iodine encapsulation capacity, positioning it as a potential replacement for traditional materials like RDX and heat‐resistant explosives such as HNS, with comparability to PYX.

Published: August 2024

AbstractIn this work, fusible microspheres loaded with radiopaque agents as an embolic agent for transcatheter arterial embolization (TAE) are developed. A poly(ethylene glycol) (PEG) and poly(ε‐caprolactone) (PCL) multi‐block copolymer basing polyurethane (PCEU) is synthesized and fabricated into blank microspheres (BMs). The microspheres are elastic in compression test. A clinical contrast agent lipiodol is encapsulated in the microspheres to receive fusible radiopaque microspheres (FRMs). The sizes of FRMs are uniform and range from 142.2 to 343.1 µm. The encapsulated lipiodol acts as the plasticizer to reduce the melting temperature point (Tm) of PECU microspheres, thus, leading to the fusion of microspheres to exhibit efficient embolization in vivo. The performance of FRMs is carried out on a rabbit ear embolization model. Serious ischemic necrosis is observed and the radiopacity of FRMs sustains much longer time than that of commercial contrast agent Loversol in vivo. The fusible and radiopaque microsphere is promising to be developed as an exciting embolic agent.

Published: August 2024

AbstractHere, a trident molecule doping strategy is introduced to overcome both cohesion‐adhesion trade‐off and adhesion‐switchability conflict, transforming commercial polymers into tough yet photo‐switchable adhesives. The strategy involves initial rational design of new trident photoswitch molecules namely TAzo‐3 featuring azobenzene and hydroxy‐terminated alkyl chains involved rigid‐soft tri‐branch structure, and subsequent doping into commercial polycaprolactone (PCL) via simple blending. Unique design enables TAzo‐3 as a versatile dopant, not only regulating the internal and external supramolecular interaction to balance cohesion and interface adhesion for tough bonding, but also affording marked photothermal effect to facilitate rapid adhesive melting for great photo‐switchability. Thus, the optimal TAzo‐3‐doped PCL (TAzo‐3@P) displays markedly‐improved bonding performance on diverse substrates compared to linear azobenzene‐doped PCL and pure PCL. Impressively, TAzo‐3@P on polymethyl methacrylate (PMMA) attains large room‐temperature adhesion strength of 6.7 MPa – surpassing most reported adhesives and many commercial adhesives on PMMA, along with easy photo‐induced detachment with remarkable switch ratio of 2.09 × 105. Besides, TAzo‐3@P can also act as “permanent” adhesives for only adhesion, demonstrating excellent multi‐reusability, anti‐freezing and waterproof ability. Mechanism studies unveil that the switchable adhesion is closely linked with the dopant molecule structure while rigid‐soft coupled trident structures and hydroxy‐terminated alkyl chains are key factors.
Zero‐Biased Bionic Fingertip E‐Skin with Multimodal Tactile Perception and Artificial Intelligence for Augmented Touch Awareness
Authors: Guo Xinge , Sun Zhongda , Zhu Yao , Lee Chengkuo 
Published: August 2024

AbstractElectronic skins (E‐Skins) are crucial for future robotics and wearable devices to interact with and perceive the real world. Prior research faces challenges in achieving comprehensive tactile perception and versatile functionality while keeping system simplicity for lack of multimodal sensing capability in a single sensor. Two kinds of tactile sensors, transient voltage artificial neuron (TVAN) and sustained potential artificial neuron (SPAN), featuring self‐generated zero‐biased signals are developed to realize synergistic sensing of multimodal information (vibration, material, texture, pressure, and temperature) in a single device instead of complex sensor arrays. Simultaneously, machine learning with feature fusion is applied to fully decode their output information and compensate for the inevitable instability of applied force, speed, etc, in real applications. Integrating TVAN and SPAN, the formed E‐Skin achieves holistic touch awareness in only a single unit. It can thoroughly perceive an object through a simple touch without strictly controlled testing conditions, realize the capability to discern surface roughness from 0.8 to 1600 µm, hardness from 6HA to 85HD, and correctly distinguish 16 objects with temperature variance from 0 to 80 °C. The E‐skin also features a simple and scalable fabrication process, which can be integrated into various devices for broad applications.

Published: August 2024

AbstractDipole moment arrangement in organic semiconductors plays a critical role in affecting the intermolecular packing, determining optoelectronic properties and device performance. Here, to get the desired fill factor (FF) values in organic solar cells (OSCs), the local dipole of non‐fullerene acceptors (NFAs) is modulated by changing the molecular asymmetries. Two NFAs, AA‐1 and AA‐2 are designed and synthesized, which have different substitutions of alkyl and alkoxyl groups. The unidirectional asymmetry in AA‐2 creates distinct local dipoles, while the bidirectional asymmetry in AA‐1 mitigates dipole variation. Despite the minimal impact on monomolecular properties, the local dipole moment significantly influences terminal group packing modes in the film state. This, in turn, enhances the relative dielectric constant, prolongs exciton lifetime, and reduces sub‐bandgap defect states. Consequently, PBDB‐TF:AA‐2‐based OSCs achieve an exceptional FF of 0.830 and a power conversion efficiency (PCE) of 18.3%, with a ternary device reaching a PCE of 19.3%. This work highlights the potential of dipole modulation in material design to get ideal FF values for high‐performance OSCs.

Published: August 2024

AbstractAimThe overdose of caffeine, a cytochrome P450 1A2 probe, in young women has become a problem. The aim of this study was to evaluate possible drug interactions between intentionally overdosed caffeine (12 g) and oral contraceptive doses of ethinyl estradiol prescribed to a young woman in a suicide attempt.MethodsThe serum concentrations of caffeine in the patient and the time‐dependent ethinyl estradiol inhibition of caffeine oxidation in vitro were evaluated.ResultsThe serum concentration of caffeine 4 h after overdose was 136 μg/mL; from the data obtained between 4 and 28 h after overdose, the half‐life was estimated to be 33 h, which is many times larger than the normal value. Prescribed ethinyl estradiol prolonged caffeine elimination in vivo and inhibited paraxanthine formation, as evidenced by the low serum concentrations. In human liver microsomes, ethinyl estradiol (50 nM) inhibited half of caffeine N3‐demethylation. Pre‐incubation of human liver microsomes with ethinyl estradiol resulted in a powerful time‐dependent inhibitory effect on caffeine N3‐demethylation in human liver microsomes.ConclusionThese results suggest that a prescription history of contraceptives at clinical doses may have a strong effect on the pharmacokinetics of overdosed caffeine in young women, resulting in dangerous drug interactions.

Published: August 2024

AbstractSilver vanadate nanorods were synthesized for the first time via co‐precipitation, followed by ambient drying. X‐ray diffraction (XRD), energy dispersive X‐ray (EDX), and scanning electron microscope (SEM) analyses were utilized to investigate the structure and morphology of the nanorods. The results of these analyses confirmed the fabrication of silver vanadate nanorods. Then, to check the ability of these nanostructures to be used in the smart window, their optical properties, including the visible–ultraviolet absorption spectrum and photoluminescence (PL), were studied. The results showed that this nanostructure has maximum absorption and emission at wavelengths of 530 and 670 nm, respectively. Next, the new smart window was made with a layer of silver vanadate nanorods, and wheat, barley, millet, and beet were placed under this smart window to perform phytochemical tests. It was observed that silver vanadate nanorods could shift the green wavelength to higher wavelengths and efficiently improve the phytochemical properties of the mentioned plants.

AbstractThe research outlined a novel approach for creating a sensitive and efficient ratio fluorescent probe for ciprofloxacin (CIP) detection. The method used the biomass materials passionfruit shell and diethylenetriamine as carbon and nitrogen sources, respectively, to prepare blue fluorescent carbon quantum dots (b‐CQDs) with an average size of 3.29 nm and a quantum yield of 19.6% by a hydrothermal method. The newly designed b‐CQDs/riboflavin ratio fluorescent probe demonstrates a distinct advantage for CIP monitoring, exhibiting a marked increase in fluorescence intensity at 445 nm upon interaction with CIP, while maintaining a stable intensity at 510 nm. In the water system, the I445 nm/I510 nm ratio of the fluorescent probe showed a significant linear relationship with CIP at the concentrations of 0–250 μmol·L−1, and the probe boasts a low detection limit of 0.86 μmol·L−1. The outstanding selectivity, broad detection range, low detection limits, and high quantum yield of the b‐CQDs highlight their significant potential in the development of advanced sensing probes for efficient detection of ciprofloxacin, offering promising insights for future sensor technology advancements.

AbstractThe present work investigates the structural and luminescence behaviour of Dy3+‐Sm3+ co‐doped glass ceramics obtained through heat treatment of precursor glasses. The growth of SiO2 polycrystalline particles and evolution of these crystallites in the glass domain are witnessed via XRD and FESEM study. The presence of network vibrational bands, hydroxyl groups and the increased quantity of bridging oxygens (BOs) in glass ceramics are analysed through FTIR spectroscopy study. The absorption study (UV–Visible–NIR) showed the possible electronic transitions of Dy3+ and Sm3+ ions. The red shift in the absorption band edges and the lower bandgap values are obtained as a result of improved heat treatment in glass ceramics. Emission studies show the enhanced luminescence intensity of glass ceramics under 350 and 402 nm excitations. Decay measurement of glass ceramics showed the improved lifetimes of Dy3+ and Sm3+ ions to have appeared in microseconds (×10−6 s). The colour characteristics of glass ceramics analysed using CIE colour chromaticity diagram and correlated colour temperature (CCT) values suggest the neutral to cool white light emissions. Therefore, prepared glass ceramics with SiO2 polycrystalline phase are considered to be suitable materials in cool white LEDs applications.

AbstractSeeing mathematics teaching as a very demanding and responsible process while having in mind the importance of mathematical knowledge for students of technical faculties, this paper aims to present heuristics for student classification according to their predicted mathematical success. Over the last few decades, the process of informatization of universities has resulted in new challenges universities are faced with. Due to the widespread use of educational databases, which opens new possibilities for educational data mining and analyses, machine learning algorithms have become a very popular tool for predicting students' academic performance. The decision tree algorithm is used in this paper for the classification and prediction of students' mathematical performance and it is trained on the data collected from the educational information system. The experimental results show that the model accuracy is 72% with an error rate of 0.28. The implementation of the Decision Tree Model to predict whether a student will pass, fail or be conditional in mathematical courses is important for both teachers and students, as well as for universities. Students' performance is one of the major keys in evaluating the quality of the teaching process, but also for evaluating the overall success of the university itself. As mathematics is considered a basic and important discipline, it is clear why predicting students' mathematical achievement is crucial for all levels of university organization.

Key Clinical MessageEpidural lymphoma of the lumbosacral region is a rare condition that manifests with back pain and nonspecific neurological symptoms. Our case which was diagnosed with diffuse large B‐cell lymphoma, highlights the importance of recognizing early lymphoma symptoms to enable timely treatment and improved outcomes.AbstractLymphoma rarely presents in the lumbosacral epidural space. Initial presentations of lymphoma are of paramount importance in the timely diagnosis and management of the disease. We report a 42‐year‐old woman presented with 4 years of low back pain and progressive right lower extremity paresthesia. Lumbar MRI revealed an epidural soft tissue lesion compressing nerves at L4 to the coccyx. Laminectomy and tumor resection were performed. Pathologic findings confirmed diffuse large B‐cell lymphoma. We systematically reviewed the literature on lymphomas with lumbar epidural space involvement reported since 1990. Twenty‐four cases from 19 reports were identified. The mean age of lumbar epidural lymphoma cases was 39.5 ± 17.8 years, and 72% were male. The most common subtype was diffuse large B‐cell lymphoma, and common presentations included back pain, lower extremity neurological deficits, and bowel/bladder dysfunction. Overall, lymphomas presenting in the spine can pose diagnostic challenges owing to nonspecific initial symptoms. Our case highlights the importance of recognizing early lymphoma symptoms to enable timely treatment and improved outcomes.
Cationic or Neutral: Dependence of Photophysical Properties of Bis‐Alkynylphosphonium Pt(II) Complexes on Ancillary Ligand
Authors: Paderina Aleksandra , Sizova Anastasia , Grachova Elena 
Published: August 2024

AbstractA series of D‐π‐A alkynylphosphonium salts with different linker between donor and acceptor groups was used to synthesize two series of trans‐bis‐alkynylphosphonium Pt(II) complexes with different ancillary ligands (triphenylphosphine, P series, and cyanide, CN series). The nature of the ancillary ligand manages the overall charge and emission properties of the complexes obtained. In addition, the variation of the linker in alkynylphosphonium ligands allows fine‐tuning the luminescence wavelength. Dicationic series P is unstable in solution under UV excitation, whereas in the solid state, these complexes are the first example of phosphorescent trans‐phosphine‐bis‐alkynyl Pt(II) compounds. Neutral series CN demonstrates bright emission in solution, including dual emission for 2CN complex with biphenyl linker in alkynylphosphonium ligand. However, in the solid state for the CN series drastic decrease in the emission quantum yield compared to the P series was observed. DFT calculations reveal the complicated emission nature for the both P and CN series with various contributions of 3ILCT, 3LLCT and 3MLCT states. However, in the naphthyl‐containing derivatives 3P and 3CN, the dominating 3LC character with some admixture of CT states is postulated.
