Objectives: The main objective of the study was to evaluate and compared the surface roughness and microhardness of three bulk-fill (ACTIVA Bioactive Restorative, SonicFill 2 SingleFill and SDR Flow Plus) and one conventional (G-aenial Posterior) composite resin at different depths.
Materials and Methods: Eighty disc-shaped composite resins (6mm diameter, 2mm height) were polymerized as recommended and then subjected to the appropriate finishing and polishing procedure. Transparent strips were placed between the samples before polymerization to evaluate the hardness at different depths (0-2mm and 2-4mm) of the bulk-fill composites. Microhardness was evaluated with a Vickers hardness tester and roughness was evaluated with an optical profilometer. The ANOVA and Tukey multiple comparisons were performed for the statistical evaluation of microhardness and ANOVA was performed for roughness.
Results: No statistically significant difference was determined between the composite materials in respect of surface roughness (p=0.336). It was generally observed that as the layer thickness increased in all the materials, the hardness values decreased (p

Published: June 2023

Zambia and Ethiopia are two countries from southern and eastern of Africa due to their geographical location and other factor the environment condition is different. The research aims at identifying and analszing the technical performance issues of Grid tide Inverter (GTI) for PV system due to operating climate and others factors. In Zambia the study focused on the two main solar plants which is under ZESCO national grid at malty facility zone (MFZ), the first one is the 54 megawatts Bangweulu solar power plant by Neon Investment of France, second one is 34MW Ngonye solar photovoltaic (PV) plant. In Ethiopia eight min off-grid site under Ethiopian Electric Utility(EEU) is included. Beltu, Behima, Mino, Ungoge, Korhele,Tum, Omorate and Kofetu. A survey is conducted focusing on identifying and analyzing the technical performance issues of GTI in the above-mentioned area.
Using Microsoft excel the environmental \climate condition, Solar radiation, Air temperature, Rain falls and Wind of the two country Zambia and Ethiopia is investigated and analysedfor each selected site. A questionnaire and a Sime structure interview is conducted. The basic inverter challenges are investigated from the collected data and the problem is analyzed based on the specific inverter data sheet. The data sheet of the inverter for each site under this study.
Finally, the real-time performance of the inverter of the off-grid PV mini-grid system installed in a small remote town in Ethiopia and on-grid PV system from Zambia at multi facility zone is analysed using measured meteorological data. From on- grid and off-grid inverter performance challenges, which the researcher collected from different plant the main ones are climate or environmental effect and also over load. Overload is one of the frequent challenges in koftu, behama and amorita this can be due to high population growth and unexpected power demand from the community.
Environmental condition affects almost all solar plant site which is under this study. If we compere the climate of east which is Addis Ababa Ethiopia and southern of Africa Zambia Lusaka. The temperature of Lusaka is higher than Addis Ababa by 5.63°C and even in the plant under this study, temperature rise is one of the challenges on the inverter performance, sensitive electronic component bent due to excessive temperature.
On the other side in Ethiopia Addis Ababa excessive rain affect the inverter. Finally, Addis Ababa has about 1.32 times more rainfall than Lusaka, (Addis Ababa’s 79.54mm vs Lusaka’s average of 60.34mm). For that reason, most of the inverter in Ethiopia on the mini off-grid site are affected by heavy rain condition.

AbstractBackgroundAdvancements in deep‐learning based synthetic computed tomography (sCT) image conversion methods have enabled the development of magnetic resonance imaging (MRI)‐only based radiotherapy treatment planning (RTP) of the brain.PurposeThis study evaluates the clinical feasibility of a commercial, deep‐learning based MRI‐only RTP method with respect to dose calculation and patient positioning verification performance in RTP of the brain.MethodsClinical validation of dose calculation accuracy was performed by a retrospective evaluation for 25 glioma and 25 brain metastasis patients. Dosimetric and image quality of the studied MRI‐only RTP method was evaluated by a direct comparison of the sCT‐based and computed tomography (CT)‐based external beam radiation therapy (EBRT) images and treatment plans. Patient positioning verification accuracy of sCT images was evaluated retrospectively for 10 glioma and 10 brain metastasis patients based on clinical cone‐beam computed tomography (CBCT) imaging.ResultsAn average mean dose difference of Dmean = 0.1% for planning target volume (PTV) and 0.6% for normal tissue (NT) structures were obtained for glioma patients. Respective results for brain metastasis patients were Dmean = 0.5% for PTVs and Dmean=1.0% for NTs. Global three‐dimensional (3D) gamma pass rates using 2%/2 mm dose difference and distance‐to‐agreement (DTA) criterion were 98.0% for the glioma subgroup, and 95.2% for the brain metastasis subgroup using 1%/1 mm criterion. Mean distance differences of <1.0 mm were observed in all Cartesian directions between CT‐based and sCT‐based CBCT patient positioning in both subgroups.ConclusionsIn terms of dose calculation and patient positioning accuracy, the studied MRI‐only method demonstrated its clinical feasibility for RTP of the brain. The results encourage the use of the studied method as part of a routine clinical workflow.

Published: June 2023

AbstractOral disease is one of the most common conditions worldwide, negatively affecting general health, reducing the quality of life, and often developing into systemic illness. However, the design of therapeutic agents for oral diseases is challenging due to various unique features of the oral cavity, including its wet and dynamic environment and curved shape. Herein, the development of highly biocompatible mucoadhesive functional hydrogels for oral applications is reported, generated by introducing bio‐inspired phenolic moieties into a pectin polymer. Pyrogallol‐functionalized pectin (Pec‐PG) can be crosslinked in situ via autoxidation without chemical agents and readily fabricated as various formulations. Sprayable Pec‐PG hydrogel exhibits strong mucoadhesion and outstanding hydration ability ex vivo and in vivo, thus displaying significant potential as a novel saliva substitute for dry mouth. The authors further show that topical application of mucoadhesive Pec‐PG patches pre‐loaded with corticosteroid significantly promotes the repair of diabetic oral ulcer tissue via prolonged drug release, free radical scavenging, and physical barrier effects. Moreover, similar applications for oral ulcer treatment using a pectin hydrogel modified with catechol (Pec‐CA), another phenolic moiety are demonstrated. Together, these findings suggest that mucoadhesive phenolic pectin derivatives can provide highly biocompatible, convenient, and effective hydrogel platforms for treating oral diseases.

Published: June 2023

AbstractFiber‐based electronic devices can be woven into textiles to provide comfort, durability, and integrated multi‐functionality, and will be widely used in the intelligent wearable field. Herein, by introducing elastic substrates and regulating the external tension during spinning to control the helical structure and optimize mechanical properties, multi‐functional Polyurethane@carbon nanotube (PU@CNT) stretchable fibers with high extensibility and flexibility is prepared for human motion detection and energy storage. A multi‐layered structure consisting of alternating MXene sheets and CNT films is also designed, to promote the relative resistance change of PU@CNT/MXene fibers to 212% (4 times than PU@CNT) when acting as strain sensors, whereas their volume specific capacitance reaches 196 F cm−3 (increases ≈50 times). Additionally, the capacitance of our stretchable fibers supercapacitors maintains at 91.4% and 86.2% when stretched statically (170% strain) or after hundreds of cycles (50% strain), respectively. It is proposed that MXene sheets can fill gaps between CNTs, resulting in more uniform distribution in fibers, which can improve strain sensitivity and long‐cycle capacitance retention. These PU@CNT/MXene fibers with unique multi‐layered hybrid structure and superior performance have potential applications in portable, wearable, and body‐integrated sensors and energy storage devices.

ObjectivesThe aim of this study was to investigate the functional networks in subjects with reversible cerebral vasoconstriction syndrome (RCVS) using resting‐state functional magnetic resonance imaging (rs‐fMRI).MethodsWe prospectively recruited patients with RCVS and healthy controls (HCs) between February 2017 and April 2021. The rs‐fMRI data were analyzed using graph theory methods. We compared node‐based global and regional topological metrics (Bundle 1) and network‐based intranetwork and internetwork connectivity (Bundle 2) between RCVS patients and HCs. We also explored the associations of clinical and vascular (ie, the Lindegaard index, LI) parameters with significant rs‐fMRI metrics.ResultsA total of 104 RCVS patients and 93 HCs were included in the final analysis. We identified significantly decreased local efficiency of the left dorsal anterior insula (dAI; p = 0.0005) in RCVS patients within 30 days after disease onset as compared to HCs, which improved 1 month later. RCVS patients also had increased global efficiency (p = 0.009) and decreased average degree centrality (p = 0.045), clustering coefficient (p = 0.033), and assortativity values (p = 0.003) in node‐based analysis. In addition, patients with RCVS had increased internetwork connectivity of the default mode network (DMN) with the salience (p = 0.027) and dorsal attention (p = 0.016) networks. Significant correlations between LI and regional local efficiency in left dAI (rs = −0.418, p = 0.042) was demonstrated.InterpretationThe significantly lower local efficiency of the left dAI, suggestive of impaired central autonomic modulation, was negatively correlated with vasoconstriction severity, which is highly plausible for the pathogenesis of RCVS.

Published: June 2023

AbstractPhotocatalytic water splitting is a promising approach to generating sustainable hydrogen. However, the transport of photoelectrons to the catalyst sites, usually within ps‐to‐ns timescales, is much faster than proton delivery (∼μs), which limits the activity. Therefore, the acceleration of abstraction of protons from water molecules towards the catalytic sites to keep up with the electron transfer rate can significantly promote hydrogen production. The photobasic effect that is the increase in proton affinity upon excitation offers means to achieve this objective. Herein, we design photobasic carbon dots and identify that internal pyridinic N sites are intrinsically photobasic. This is supported by steady‐state and ultrafast spectroscopic measurements that demonstrate proton abstraction within a few picoseconds of excitation. Furthermore, we show that in water, they form a unique four‐level lasing scheme with optical gain and stimulated emission. The latter competes with photocatalysis, revealing a rather unique mechanism for efficiency loss, such that the stimulated emission can act as a toggle for photocatalytic activity. This provides additional means of controlling the photocatalytic process and helps the rational design of photocatalytic materials.
Apparent and true mineralization during combined electro‐oxidation and electro‐coagulation on stainless steel anode
Authors: Meena Vinod Kumar , Ghatak Himadri Roy 
Published: June 2023

AbstractPresent study is a novel attempt to experimentally verify that electrochemical treatment of organic pollutants on stainless steel (SS) anode is a combination of electro‐oxidation (EO) and electro‐coagulation (EC) with quantitative estimation of individual contributions of the two mechanisms. Target organic pollutants, metformin HCl (MET‐HCl) and lamotrigine (LAM), were electrochemically treated with SS anode for this purpose. Experiments were designed using central composite rotatable design (CCRD) to assess the effect of current density (CD) and supporting electrolyte concentration (SEC) as independent process parameters. Under all conditions, the process was experimentally verified to be a combination of EO and EC. For MET‐HCl, true mineralization (TM) as a result of EO contribution varied between 50.13% and 66.64%. EO contribution and resulting TM for LAM ranged from 37.5% to 61.83%. EC contributed 30.6%–31.84% towards MET‐HCl remediation causing the TOC to be transferred from the liquid to the sludge produced (SP). EC contribution was 23.68%–35.89% for LAM remediation. Thus, apparent mineralization (AM), the sum of EO and EC contributions, ranged from 80.63% to 97.79% for MET‐HCl and 61.18% to 96.82% for LAM.Process parameters were statistically optimized using response surface methodology (RSM) to simultaneously maximize TM and AM with minimal energy consumption and maximal current efficiency. The optimized conditions were 0.83 mA/cm2 CD and 86.66 ppm SEC for MET‐HCl. The corresponding values were 1.31 mA/cm2 CD and 79.51 ppm SEC for LAM.
High performance biopolymer blend nanocomposites derived from cashew gum/polyvinyl alcohol/boehmite for flexible electronic devices

Published: June 2023

AbstractThis work reports on a bio‐based polymer blend comprised of polyvinyl alcohol/cashew gum (PVA/CG) embedded with boehmite nanoparticles to tailor the structural, thermal, mechanical properties, and electrical response. The chemical bonding between boehmite and the PVA/CG blend was confirmed by FTIR. The XRD data showed that the nanocomposite films had distinct peaks of boehmite. The SEM images revealed uniformly dispersed morphology at 5 wt% boehmite. The elemental composition of blend nanocomposites was revealed by the EDX analysis. The thermal stability of the blend increases with increasing boehmite, whereas the glass transition temperature decreases. The highest AC conductivity was achieved for PVA/CG/7 wt% boehmite, which was 4.6 times greater than the pure blend. The frequency and temperature‐dependent dielectric constant, modulus and impedance of all films were examined in conjunction with different nanoparticle loadings. Tensile strength and hardness have improved with the addition of boehmite into the PVA/CG blend whereas the elongation at break slightly decreases. The PVA/CG blend had a tensile strength of 31.17 MPa, which increased to 44.66 MPa when 7 wt% boehmite was added. Therefore, eco‐friendly PVA/CG/boehmite films with good thermal stability, mechanical strength, dielectric constant, and conductivity could be a practical green substitute for flexible electronic, charge storage, and electrochemical devices.
