Published: September 2023

Background: Diffusion-weighted MRI has potential for tissue differentiation, including cancer. It can also determine cancer histologic type. The ADC value reflects tumor cellular density, allowing tumor grading evaluation. This study aims to assess the role of DW-MRI in gynecological masses.
Methods: This prospective cross-sectional research was conducted on 30 female patients between the ages of 20 and 75 who were sent from the gynaecological department to the Radio diagnostic and Medical Imaging department at Tanta University hospitals. All patients gave their informed permission in writing. We included patients with clinically or sonographically suspected uterine and cervical lesions. Patients having indeterminate ultrasonography criteria for adnexal lesions.
Results: Resistance Index (RI) showed significant predictive value of the malignant masses (p=0.13), with an area under curve (AUC) of 0.84. An RI cutoff value of ≥0.365 could predict malignant masses with a sensitivity of 81.8% and specificity of 87.5%. T ROC curve analysis to assess the validity of ADC to discriminate malignant masses is illustrated. ADC values showed significant predictive value of the malignant masses (p<0.001*), with an area under curve (AUC) of 0.89. An ADC cutoff value of ≤1 could predict malignant masses with a sensitivity of 85.7% and specificity of 89.5%.
Conclusions: Combined ultrasound and MRI examination produced radiologic findings with 98 percent sensitivity, 92.9 percent specificity, 95 percent positive predictive value, and 97 percent negative predictive value when compared to the final pathologic diagnosis. The research indicated that DWI and ADC mapping are excellent imaging methods for discriminating benign from malignant tumours with a high degree of sensitivity and specificity. However, their effectiveness and benefits depend on a precise diagnosis of the lesions' essential features, such as their origin, size, and composition, as assessed by ultrasound and standard MRI tests.

Authors: Bello A.  , Usman J. D.  
Published: September 2023

Introduction: Cephalometry has been widely used in substantial aspects of medicine. The morphometric assessment of the orbit and familiarity with its anatomy is significant clinically in the diagnosis of lesions in the orbit and reconstructive surgeries of the face. There is an important link between diagnostic radiology and ophthalmology. Most previous studies use direct techniques on living, cadaveric specimens, or dry bones to assess the orbital dimensions.
Aim: To determine the relationship between the orbital dimensions and the increase in age.
Materials and Methods: A 5-year retrospective cross-sectional study using 255 normal skull radiographs obtained from the Department of Diagnostic Radiology of Usmanu Danfodiyo University Teaching Hospital was done. The radiographs were visualized on an illuminator and measurements of the orbital dimensions were made with the aid of a transparent ruler and a pencil. Results: The orbital dimensions of the subjects used in this study in relation to their age groups revealed a steady rise in the dimensions with the increase in age until the age range of 51-60 years when it reaches the peak value and then gradually declines. In the measurement of the interorbital distance in relation to age, it was similarly found to increase with increasing age of the subjects however reaching its peak at the age range of 31-40 years then gradually dropping.
Conclusions: The orbital dimensions show a positive correlation with increasing age.

Published: September 2023

AbstractEffective stress analysis using liquefaction parameters is often employed for the numerical analysis of soil liquefaction. However, to the best of our knowledge, liquefaction parameters that simultaneously reproduce the liquefaction strength curve and effective stress path have not been reported to date. Herein, we propose a new method to estimate the model parameters used in effective stress analysis: the liquefaction strength and pore pressure curves obtained from laboratory tests are used as targets for inverse analysis. The results confirmed that the parameters obtained by our method could reproduce the liquefaction strength, pore pressure curves, and the effective stress path with high accuracy, which was difficult to achieve using conventional methods.

Published: September 2023

AbstractThe development of stimuli‐responsive liquid metal hybrids (SrLMHs) is of great interest, owing to their ability to induce responsivity and innovative properties to liquid metal (LM) when hybridized. Various stimuli‐responsivities yield new realms for SrLMHs in the fields of human‐interactive electronics (HIEs). This review provides an overview on the development of SrLMHs for HIEs. First, discussion is on SrLMH systems regarding their configuration, the materials utilized for the establishment of new hybrid materials, various stimuli‐responsive systems, their operation mechanisms, and applications. Followed by the characterization and summary of SrLMHs, details on how SrLMHs are incorporated for HIEs, and their progression is reviewed, from a single mechanical stimulus sensing capability to multi‐modal functionality. Finally, the review concludes on the overall progress of SrLMH‐based HIEs, their advancement direction, and the challenges that still remain.

AbstractCarbon‐based supercapacitors are one of the most widely used commercial products. Organic electrolyte systems, such as tetraethylammonium tetrafluoroborate/acetonitrile (TEABF4/ACN), remain dominant after decades of development due to cost and performance advantages. However, improving the capacitance of existing carbon‐electrolyte systems not by altering the pore structure and surface properties of activated carbon is full of challenges. Herein, a non‐Faraday organic ferroelectric salt additive (diisopropylamine perchlorate, DIPAP) that can significantly increase capacitance from the standpoint of electrolyte dielectric modulation is proposed for the first time. Compared to counter ions, DIPA+ plays a vital role in capacity enhancement, in which electron‐rich N‐doped mesoporous carbon can greatly boost capacity by promoting local ion mobility. In situ Raman and theoretical studies show that small‐size DIPA+ can enter the pore and be enriched closer to electrode surfaces than TEA+ and ACN, allowing it to regulate the distribution of electric double‐layer species and dielectric properties (i.e., effective thickness of dielectric and/or relative dielectric constant), increasing capacity by up to 21.6–45.8% with only 1 wt% DIPAP while maintaining desired rate performances. The understanding of the mechanism of capacitance increase by such additives opens up new avenues for further extension of the commercialized carbon electrode‐organic electrolyte system's potential.

AbstractMultidrug resistance (MDR) is one of the major factors causing failure of non‐small‐cell lung cancer (NSCLC) chemotherapy. Real‐time and accurate differentiation between drug‐resistant and sensitive NSCLC is of primary importance for guiding the subsequent treatments and improving the therapeutic outcome. However, there is no effective method to provide such an accurate differentiation. This study creates an innovative strategy of integrating H2O2‐responsive nanoprobes with the quantitative T1‐mapping magnetic resonance imaging (MRI) technique to achieve an accurate differential diagnosis between drug‐resistant and sensitive NSCLC in light of differences in H2O2 content in the tumor microenvironment (TME). The result demonstrates that the synthesized MIL‐53(Fe)@MnO2 nanocomposites possess an excellent capability of shortening the cancer longitudinal relaxation time (T1) when meeting H2O2 in TME. T1‐mapping MRI could sensitively detect this T1 variation (about 2.6‐fold that of T1‐weighted imaging (T1WI)) to accurately differentiate the H2O2 content between drug‐resistant and sensitive NSCLC. In addition, the quantitative data provided by the T1‐mapping MRI dedicates correct comparison across imaging tests and is more reliable than T1WI, thus giving it a chance for precise assessment of the anti‐cancer effect. This innovative strategy of merging TME adaptable nanoprobes with the quantitative MRI technique provides a new approach for the precise diagnosis of multidrug‐resistant NSCLC.

Published: September 2023

AbstractBreast cancer is characterized by an acidic micro‐environment. Acidic extracellular pH gives cancer cells an evolutionary advantage, hence, neutralization of the extracellular pH has been considered as a potential therapeutic strategy. To address the issue of systemic pH alteration, an approach based on the targeted delivery of the buffering solution to the tumor region is investigated. The method relies on the use of low frequency ultrasound and sono‐sensitive liposomes loaded with buffers at alkaline pH (LipHUS). After the i.v. injection of LipHUS, the application of ultrasound (US) at the sites of the pathology induces a local increase of pH that results highly effective in i) inhibiting primary tumor growth, ii) reducing tumor recurrence after surgery, and iii) suppressing metastases’ formation. The experiments are carried out on a triple negative breast cancer mouse model. The results obtained demonstrate that localized and triggered release of bicarbonate or PBS buffer from sonosensitive liposomes represents an efficient therapeutic tool for treating triple‐negative breast cancer. This approach holds promise for potential clinical translation.

AbstractMultiple cation‐composited perovskites are demonstrated as a promising approach to improving the performance and stability of perovskite solar cells (PSCs). However, recipes developed for fabricating high‐performance perovskites in laboratories are always not transferable in large‐scale production, as perovskite crystallization is highly sensitive to processing conditions. Here, using an in situ optical method, the ambient temperature effect on the crystallization process in multiple cation‐composited perovskites is investigated. It is found that the typical solvent‐coordinated intermediate phase in methylammonium lead iodide (MAPbI3) is absent in formamidinium lead iodide (FAPbI3), and nucleation is almost completed in FAPbI3 right after spin‐coating. Interestingly, it is found that there is noticeable nuclei aggregation in Formamidinium (FA)‐based perovskites even during the spin‐coating process, which is usually only observed during the annealing in MAPbI3. Such aggregation is further promoted at a higher ambient temperature or in higher FA content. Instead of the general belief of stress release‐induced crack formation, it is proposed that the origin of the cracks in FA‐based perovskites is due to the aggregation‐induced solute depletion effect. This work reveals the limiting factors for achieving high‐quality FA‐based perovskite films and helps to unlock the existing narrow processing window for future large‐scale production.
Soft Tactile Coil‐Based Sensor for Misalignment Detection of Adhesive Fibrillary Gripping Systems
Authors: Herter Simon , Stopp Philipp , Fischer Sarah C.L. 
Published: September 2023

AbstractMicropatterned dry adhesive systems are a promising alternative to conventional handling solutions. However, the use of these gripping systems still requires precise manual adjustment of the gripping parameters. To address this limitation, a coil‐based sensor is designed to enable automatic detection of the attachment process. The sensor consists of three sensing, one transmitting coil, a conductive film, and a compliant layer. The components are optimized to achieve reproducible, precise measurements, and minimize hysteresis effects of the components. A mathematical concept to calculate the geometrical relations between the gripping object and the gripper is established based on triangulation. The functionality of the sensor system is demonstrated in contact experiments with a glass substrate under different tilt angles, and an accuracy of 0.042 degree is achieved. The sensor system not only allows precise detection of the misalignment angle but also fast estimation of the qualitative direction of misalignment with minimal compression. This is interesting for scaling the sensor system to industrial pick‐and‐place applications as it promises to speed up the handling times and reliability of the fibrillary adhesives. In the future, the system needs to be extended to capture more complex objects and properties to be applicable to more handling problems.

AbstractThe development of lithium‐sulfur (Li‐S) batteries is severely limited by the shuttle effect and instability of Li‐metal anode. Constructing Li‐ion S batteries (LISBs), by using more stable commercial graphite (Gr) anode instead of Li‐metal, is an effective way to realize long‐cycle‐life Li‐S batteries. However, Gr electrode is usually incompatible with the ether‐based electrolytes commonly used for Li‐S batteries due to the Li+‐ether complex co‐intercalation into Gr interlayers. Herein, a solvent molecule structure regulation strategy is provided to weaken the Li+‐solvent binding by increasing steric hindrance and electronegativity, to accelerate Li+ de‐solvation process and prevent Li+‐ether complex co‐intercalation into Gr anode. Meanwhile, the weakly solvating power of solvent can suppress the shuttle effect of lithium polysulfides and makes more anions participate in Li+ solvation structure to generate a stable anion‐derived solid electrolyte interface on Gr surface. Therefore, a LISB coin‐cell consisting of lithiated graphite anode and S@C cathode displays a stable capacity of ≈770 mAh g−1 within 200 cycles. Furthermore, an unprecedented practical LISB pouch‐cell with a high Gr loading (≈10.5 mg cm−2) also delivers a high initial capacity of 802.3 mAh g−1 and releases a stable capacity of 499.1 mAh g−1 with a high Coulombic efficiency (≈95.9%) after 120 cycles.
