Published: July 2020

Corrosion problems that occur in all fields in engineering activities cause high negative economic impacts, therefore research into operations of different wear mechanisms is a prerequisite for mitigating the effects of corrosion problems can reduce economic loss. Groundwater is vital and the sole resource in most of the studied region in the city of kufra. In this study, some physical and chemical analysis studies were conducted on the water samples in the study area, which included: pH, total soluble salts, sulfate, chloride, calcium and magnesium. The values of these concentrations in the studied water samples indicate that they constitute a chemically suitable environment for corrosion and precipitation reactions, additionally, the pH values for the studied water samples ranged between (6.02 - 8.2), EC ranges between (266 - 3054) microseism/cm, temperature values ranged from 34.8 C0 to 37.4 C0, TDS between (270 - 1936 ppm). It was found that the Aggressiveness coefficient ranged between (9.03 to 11.58) and this indicates that the water in this region is highly corrosive and the Ryzner coefficient ranges between (8.98 -11.49), which indicates the water condition is the cause of corrosion. The Langelier coefficient index shows that the negative values are the cause of the increase in wear rate values from -2.73 to -0.89.

Published: July 2020

AbstractBulk heterojunction (BHJ) processing technology has had an irreplaceable role in the development of organic solar cells (OSCs) in the past decades due to the significant advantages in achieving high‐power conversion efficiency (PCE). However, the difficulty in exploring and regulating morphology makes it inadequate for upscaling large‐area OSCs. In this work, printable high‐performance ternary devices are fabricated by a pseudo‐planar heterojunction (PPHJ) strategy. The fullerene derivative indene‐C60 bisadduct (ICBA) is incorporated into PM6/IT‐4F system to expand the vertical phase separation and facilitate an obvious PPHJ structure. After the addition of ICBA, the IT‐4F enriches on the surface of active layer, while PM6 is accumulated underneath. Furthermore, it increases the crystallinity of PM6, which facilitates exciton dissociation and charge transfer. Accordingly, 1.05 cm2 devices are fabricated by blade‐coating with an enhanced PCE of 14.25% as compared to the BHJ devices (13.73%). The ternary PPHJ strategy provides an effective way to optimize the vertical phase separation of organic semiconductor during scalable printing methods.
Functionalized Zn@ZnO Hexagonal Pyramid Array for Dendrite‐Free and Ultrastable Zinc Metal Anodes
Authors: Kim Ji Young , Liu Guicheng , Shim Ga Young , Kim Hansung , Lee Joong Kee 
Published: July 2020

AbstractHere, an electrode comprising a Zn hexagonal pyramid array (HPA) coated with a functionalized ZnO layer (Zn@ZnO HPA) is prepared using a periodic anodizing technique. The HPA structure markedly increases the electroactive surface area of Zn anode, thus decreasing the local current density. Furthermore, the functionalized ZnO coating layer has a gradient thickness that plays an important role in the selective deposition of Zn ions and the mitigation of side reactions at the interface. The electrochemical stability of the Zn@ZnO HPA electrode, which is closely related to the electroactive surface area and charge transfer resistance, is determined by the “split” value, i.e., ratio of current‐off to current‐on time, a parameter of the periodic anodizing process. Compared with the pristine Zn‐based symmetric cell, the Zn@ZnO HPA‐based symmetric cell is safely operated in the investigated experimental range with the 10‐fold improved running life and 25‐fold enhanced current density without Zn dendrite growth. Moreover, the Zn@ZnO HPA/MnO2 battery exhibits outstanding long‐term cyclability (nearly 100%) with greater than 99% Coulombic efficiency after 1000 cycles at a current density of 9 A g−1. This periodic anodizing technique for ultrastable Zn metal anodes is expected to contribute to the development of inherently safe energy storage systems.
Highly Efficient, Bright, and Stable Colloidal Quantum Dot Short‐Wave Infrared Light‐Emitting Diodes

Published: July 2020

AbstractUnbalanced charge injection is deleterious for the performance of colloidal quantum dot (CQD) light‐emitting diodes (LEDs) as it deteriorates the quantum efficiency, brightness, and operational lifetime. CQD LEDs emitting in the infrared have previously achieved high quantum efficiencies but only when driven to emit in the low‐radiance regime. At higher radiance levels, required for practical applications, the efficiency decreased dramatically in view of the notorious efficiency droop. Here, a novel methodology is reported to regulate charge supply in multinary bandgap CQD composites that facilitates improved charge balance. The current approach is based on engineering the energetic potential landscape at the supra‐nanocrystalline level that has allowed to report short‐wave infrared PbS CQD LEDs with record‐high external quantum efficiency in excess of 8%, most importantly, at a radiance level of ≈5 W sr−1 m2, an order of magnitude higher than prior reports. Furthermore, the balanced charge injection and Auger recombination reduction has led to unprecedentedly high operational stability with radiance half‐life of 26 068 h at a radiance of 1 W sr−1 m−2.

Published: July 2020

AbstractThe energy storage performance of sodium‐ion batteries has been greatly improved by pairing ether‐based electrolytes with high‐capacity alloy‐type anodes. However, the origin of this performance improvement by a unique electrode/electrolyte interface has yet to be explored. To understand such results, herein, the deterministic and distinct interfacial chemistries and solid electrolyte interphase (SEI) layers in both the ether‐ and ester‐based electrolytes are described, as verified by post mortem, in‐depth X‐ray photoelectron spectroscopy, and electron energy loss spectroscopy analyses, employing a hierarchical Bi/C composite anode as the model system. In the ether‐based electrolyte, fast sodium‐ion storage kinetics and structural integrity are achieved due to the highly ionic‐conducting and robust multi‐layered SEI consisting of an inner dense bismuth‐containing inorganic and outer polyether layer. No drastic capacity decay is observed over 1000 cycles and high capacity retention of 89% is achieved, increasing rates from 0.1 to 10 A g−1. The benefit of this SEI is confirmed to demonstrate a high energy density of 162 Wh kg−1 in a full‐cell and a high areal capacity of 3.3 mAh cm−2 even at a high mass loading of 11 mg cm−2, which is nearly equivalent to the loading of commercial lithium‐ion battery anodes.
Separation of liquid–liquid dispersion in a batch settler: CFD‐PBM simulations incorporating interfacial coalescence
Authors: Thaker Abhijeet H. , Buwa Vivek V. 
Published: July 2020

AbstractSeveral commercially important chemical processes involve liquid–liquid phase separation. In the present work, we have developed a multi‐fluid Eulerian CFD model using OpenFOAM that incorporates binary and interfacial coalescence processes. We simulated separation of kerosene dispersed in water in a batch settler and validated the predictions using the measurements of time‐evolution of coalescing and settling interfaces, local dispersed‐phase volume fraction (αO) and drop size distribution (DSD). Simulations are performed to understand the contributions of binary and interfacial coalescence processes to the phase separation process. While the time‐evolution of coalescing and settling fronts can be predicted reasonably well using the two‐fluid model with empirically‐corrected drag models, local αO and DSD could not be predicted. We have shown that the comprehensive multi‐fluid Eulerian model, which incorporates binary and interfacial coalescence, predicts the time‐evolution of the coalescing and settling fronts, local αO and the DSD in an excellent agreement with the measurements.

Published: July 2020

AbstractDrying process of industrial green in‐process products especially those susceptible to cracking, need great care, and optimally arrangement of parameters of convective drying. Intermittent drying is a new technique in drying area and is a promising solution for product quality enhancement. The intermittent drying with variable air temperature and the intermittent drying with variable air humidity are the most used techniques. The current study is devoted to 3D modeling and simulation of intermittent drying with variations of both air humidity and temperature and it is then compared with each of the cases of the intermittent drying with variable air temperature and the intermittent drying with variable air humidity. It was observed that the best dried product quality was obtained in intermittent drying with periodic changes of air temperature. Vapor condensation in the intermittent drying with variable air humidity is an undesirable phenomenon that significantly reduces the effectiveness of this process.

AbstractBackgroundThis study evaluated the association of co‐exposure to different psychosocial factors with poor psychological well‐being of Korean regular workers.MethodsThis was a secondary analysis of data from the fifth Korean Working Conditions Survey, conducted in 2017. Multiple logistic regression was used to determine adjusted odd ratios (aORs) and 95% confidence intervals for poor psychological well‐being associated with self‐reported psychosocial factors. Poor psychological well‐being was measured using the Well‐Being Index of the World Health Organization. For each question on psychosocial factors (long weekly working hours, lack of decision latitude, work pressure, lack of autonomy, lack of role clarity, organizational injustice, lack of reward, and lack of support from managers), answers of “always” and “most of the time” were classified as affirmative and answers of”sometimes,” “rarely,” and “never” were classified as negative.ResultsPoor psychological well‐being was significantly associated with most individual work stressors for both sexes (aORs = 1.22‐1.83). Furthermore, poor psychological well‐being had a positive association with co‐exposure to different psychosocial factors (aORs = 1.71‐8.08). Co‐exposure to an increasing number of psychosocial factors showed greater association with poor psychological well‐being.ConclusionWe found that poor psychological well‐being was associated with co‐exposure to psychosocial factors in Korean workers in regular employment. Thus, we suggest that employers provide comprehensive measures that will protect workers from simultaneous exposure to adverse psychosocial factors.

Published: July 2020

BackgroundAbuse can be a cause of pediatric duodenal injury. Patients who have been injured by abuse tend to have delay before medical examination, they may therefore have especially poor prognosis.Case presentationA 3‐year‐old boy presented with abdominal pain and was diagnosed with duodenal perforation. He was urgently transferred to our hospital for surgery. There was no clear history of trauma according to initial parent interviews, but old bruises were observed in several places. Paternal remarks about the injury mechanism were contradictory to bruit findings. Eventually, the mother reported daily paternal domestic violence against the patient. Duodenal perforation was considered to be caused by physical abuse, and emergent surgery was carried out. Intraoperative findings revealed transection at the horizontal part of the duodenum. Primary repair was difficult due to severe damage, so duodenojejunostomy was undertaken.ConclusionDuodenojejunostomy was successfully carried out as emergent surgery for severely damaged duodenal transection.
