Using primary data collected from in-depth interviews with 11 practical experts who have been working in the commodity industry for 7 years on average and using the Bollinger Bands tool for 3 years at least, the article shows that Bollinger Bands' signs on price forecasts or making decisions to buy or sell in the future trading of agricultural products in Vietnam are highly appreciated because of their accuracy. In addition, by using the Analytical Hierarchy Process (AHP) approach, the research indicates that there is no big difference in the effectiveness of Bollinger Bands’ application in future transactions for coffee, corn, wheat, soybean and soybean oil. However, applying Bollinger Bands in coffee futures’ trading is the most effective. In addition, the study also emphasizes the combination of Bollinger Bands with other technical analysis tools such as RSI, MACD, Fibonacci, Ichimoku, and CCI, to improve transaction efficiency.

Published: November 2022

AbstractHigh‐performance perovskite film with superior internal and surface qualities is critical for perovskite solar cells (PSCs) but hardly achievable due to the rapid crystallization rate of perovskite itself. Herein, a novel technique by in situ manipulating perovskite crystal growth and modifying the surface properties is developed using organic passivating agent‐assisted polydimethylsiloxane membrane as a facial mask (FM) of perovskites. By placing the perovskite‐precursor films with their faces toward the designed FM during thermal annealing, a favorable microenvironment is constructed for incubating high‐quality perovskite films with smooth surface, enhanced vertical orientation of (100) plane, and well‐adjusted interfacial energy levels. With this versatile FM incubation technique, efficient PSCs for both methylammonium (MA)‐based and formamidinium (FA)‐MA‐Cs mixed perovskite systems are facilely fabricated, delivering excellent humidity/thermal stabilities and promising efficiencies up to 21.4% with an improved open‐circuit voltage of 1.15 V in MA‐based devices. This study not only provides a facile and efficient approach to rationally manage the perovskite growth process, but also reveals the fundamental characteristics of high‐quality perovskite films comprehensively for the construction of efficient and stable PSCs.

AbstractAdditive manufacturing (AM) is the key to creating a wide variety of 3D structures with unique and programmable functionalities. Direct ink writing is one of the widely used AM technologies with numerous printable materials. However, the extrude‐based method is limited by low fabrication resolution, which is confined to printing macrostructures. Herein, a new AM strategy is reported, using a low‐cost extrusion 3D printer, to create 3D microarchitectures at the macroscopic level through controlled desiccation of preprinted hydrogel scaffolds followed by infilling objective components. A printable hydrogel with a high‐water content ensures maximum shrinkage (≈99.5% in volume) of the printed scaffolds to achieve high resolution. Stable covalent cross‐linking and a suitable drying rate enable uniform shrinkage of the scaffolds to retain their original architectures. Particularly, this method can be adapted to produce liquid‐metal‐based 3D circuits and nanocomposite‐based microrobots, indicating its capability to fabricate functional and complex 3D architectures with micron‐level resolution from different material systems.

AbstractColored solar panels, realized by depositing various reflection layers or structures, are emerging as power sources for building with visual aesthetics. However, these panels suffer from reduced photocurrent generation due to the less efficient light harvesting from visible light reflection and degraded power conversion efficiency (PCE). Here, color‐patterned silicon heterojunction solar cells are achieved by incorporating luminescent quantum dots (QDs) with high quantum yields as light converters to realize an asthenic appearance with high PCE. It is found that large bandgap (blue) QD layers can convert UV light into visible light, which can notably alleviate the parasitic absorption by the front indium tin oxide and doped amorphous silicon. Additionally, a universal optical path model is proposed to understand the light transmission process, which is suitable for luminescent down‐shift devices. In this study, solar cells with a PCE exceeding 23.5% are achieved using the combination of a blue QD layer and a top low refractive index anti‐reflection layer. Based on our best knoledge,the obtained PCE is the highest for a color‐patterned solar cell. The results suggest an enhanced strategy involving incorporation of luminescent QDs with an optical path design for high‐performance photovoltaic panels with visual aesthetics.

Published: November 2022

AbstractUnderoil adhesives are intensively needed in case of oil spill caused by pipeline rupture, but remain a challenge owing to the obstruction of oil layer or their swelling in oil. Herein, a general solvent diffusion principle is demonstrated by introducing dual‐soluble “mediator” solvents to develop a new type of interfacial instability‐induced (3I) adhesives, achieving effective underoil adhesion on various substrates and blocking the oil leakage within seconds. Microscopic characterization reveals a fast and dynamic solvent exchange process that destroys the oil layer by liquid–liquid interfacial diffusion between the “mediator” solvent and oil, enabling 3I adhesives to contact the solid surfaces directly. The principle of interfacial instability‐induced liquid replacement is quite different from typical immiscible liquid replacement and is not restricted by the surface tension of solvents, surface energy, and roughness of solid surfaces, successfully directing the construction of a series of effective 3I adhesives with commercially available feedstocks. This study provides a unique clue for the design of next‐generation adhesives in complex environments.

Published: November 2022

AbstractFluid energy is one of the most common, widely distributed, and significant renewable energy sources globally, which generally exists in gases and liquids such as wind energy, airflow energy, droplet energy, water flow energy, and wave energy. Since Wang's research group first invented the triboelectric nanogenerators (TENGs) in 2012, it has been widely utilized and developed rapidly as a new energy conversion method and as a promising sensing technology. Especially in fluid sensing, the TENGs get a lot of attention. This paper comprehensively reviews the latest research on triboelectric fluid sensors (TFSs). First, the fundamental theories and basic operation modes of TFSs are briefly introduced. Then, the research status of TFSs in different functions, structural design, and output performance is summarized according to the form of fluid energy (gas‐based, liquid‐based, and multi‐phase flow‐based). In addition, the application of TFSs in different fields is also discussed in this paper. Finally, this research presents its views on the challenges and future development trends of TFSs.

Published: November 2022

AbstractInsufficient hydrogen peroxide (H2O2) in tumor microenvironment severely limits the therapeutic effect of chemodynamic therapy (CDT), while excessive glutathione (GSH) scavenges the generated hydroxyl radical (•OH) to reduce oxidative stress, making the CDT consequence even poorer. Herein, a facile yet vigorous therapeutic nanodrug, which integrates polyethylene glycol (PEG)‐functionalized gold nanodots (Au NPs) with ferrocene (Fc), is fabricated for enhanced CDT by redox dyshomeostasis with both GSH depletion and boosted oxidative stress. The constructed Au NPs‐PEG‐Fc (APF) nanodrug depletes GSH by competitive binding, catalyzes glucose to generate H2O2 with its glucose oxidase‐mimicking activity, and further catalyzes H2O2 to generate •OH through the Fc‐based Fenton reaction. Finally, it enhances redox dyshomeostasis through both the depletion of GSH and generation of •OH. Both in vitro and in vivo results show that the APF nanodrug can elevate oxidative stress to enhance the efficacy of CDT. Overall, this study provides a promising strategy for disrupting the redox balance to enhance the efficacy of CDT.

Published: November 2022

AbstractHydrated calcium silicate carbonation leads to reinforcement corrosion and strength reduction. The carbonation mechanism of Tobermorite 9 Å is researched by density functional theory calculation and ab initio molecular dynamics (AIMD). Results show that the lowest surface energy of Tobermorite 9 Å (001) slab is (001) surface. The bridge position of Ca1─Ca5 atom is the most stable adsorption position for carbon dioxide molecules. In terms of charge density difference, the results show that the Ca atom loses electrons and the O atom gains electrons. In terms of partial density of states, the results show that there are unobvious hybridization orbitals between Ca d‐ and O p‐orbitals, which leads to the formation of a very weak Ca─O bond. In terms of AIMD simulation at the temperature of 1073 K, the results show that the carbon dioxide gradually develops from adsorption to desorption on the Tobermorite 9 Å (001) surface. These findings provide profound views in understanding the carbonation of hydrated calcium silicate.

Published: November 2022

AbstractAqueous zinc‐ion batteries (ZIBs) are attractive in energy storage due to the use of aqueous electrolytes that ensures safety and ease of handling all parts in air. However, catastrophic zinc dendritic growth on zinc metal anodes impedes their practical application. Herein, Zn3(PO4)3·4H2O (ZP)‐coated zinc metal anode is introduced to effectively suppress the dendrite growth and the chemical state of the dendrites that are composed of metallic Zn0, ZnO, and Zn(OH)2is elucidated first. Significant improvement is observed for the ZP‐coated zinc metal symmetric cell. Operando synchrotron tomography demonstrates that the ZP‐coating layer ensures uniform deposition of zinc‐derived compounds by the ZP layer that scarifies itself through decomposition to P2O5, Zn0, and Zn(OH)2. Meanwhile, the local reaction between P2O5and H2O reproduces H3PO4, which provides a condition to reproduce Zn3(PO4)2·4H2O via a reaction between H3PO4and metallic Zn on the Zn metal anode. This cyclic reformation of Zn3(PO4)2·4H2O progressively prevents dendrites over the long‐term, even at high rates. The compatibility is verified in NaV3O8||ZP‐coated zinc anode cell over 1000 cycles. As a result, this finding presents a practical way for uniform deposition of Zn that can be applicable to aqueous and nonaqueous ZIBs.

AbstractBackgroundThis study aimed to investigate the characteristics of occupational injuries based on fatality, sex, and classification of occupations among construction workers using workers' compensation (WC) insurance data in South Korea.MethodsWe collected WC insurance data from the Korea Workers' Compensation & Welfare Service for all construction workers between 2009 and 2018. Data from 158,947 accepted claims for occupational injury were extracted, and the demographic features, occupational injury types, and annual trends were analyzed for fatal and nonfatal cases. The annual incidence and mortality trends of occupational injury were estimated using negative binomial regression and Poisson regression models, for injury incidence and mortality respectively.ResultsAmong a total of 158,947 occupational injury cases, there were 155,772 (98%) nonfatal injuries and 3175 (2%) fatal injuries. For all occupational injuries, Construction Elementary Workers (6th Korean Standard Classification of Occupations (KSCO) 910; 45.7%) was the most frequent occupation, followed by Construction‐Related Technical Workers (6th KSCO 772; 39.2%). The most frequent injury type was a fracture, followed by ruptures or lacerations and contusions. The incidence of all occupational injuries increased from 700.36 per 100,000 persons in 2009 to 1,195.98 per 100,000 persons in 2018. Further, deaths from injuries at work followed a significantly increasing annual trend [mortality rate ratio 1.04 (95% CI: 1.03–1.05)] from 2009 to 2018.ConclusionThe over two‐thirds increased incidence of occupational injuries and significantly increasing mortality trends for occupational injuries during the last 10 years indicate the need for aggressive intervention in occupational safety and health management within the Korean construction industry.

Published: November 2022

AbstractA CuI‐catalyzed hydrocupration and borylation protocol for the regio‐ and stereoselective borylation of ynamides utilizing pinacolatoborane (HBpin) as the borylating agent has been developed. The reaction features mild conditions, good substrate scope and functional group tolerance‐representing a highly efficient and practical method for the synthesis of regio‐ and stereoselective tri‐substituted alkenylboronates from readily available ynamides. The regioselectivity is controlled by altering substituents on the ynamides (alkyl vs aryl) and utilizing a catalytic species [LCuH] generated in situ from HBpin and [LCuX]. Suzuki coupling and other transformations highlight the synthetic utility of the method.

AbstractBackgroundSinonasal lymphoma (SL) is a heterogeneous, underrecognized neoplastic disorder with limited outcomes data. We sought to better define outcomes by subtype and treatment at 2 referral centers over the past 2 decades.MethodsDemographics, clinicopathologic data, and treatment outcomes for patients treated for SL were queried from January 1, 2000 to December 31, 2021 at 2 tertiary academic medical centers.ResultsEighty‐four patients were included, with an average age at diagnosis of 63.4 ± 15 years. There were 34 females (40.5%). The majority of patients had an Eastern Cooperative Oncology Group (ECOG) score of <2 (76.2%) and the most common presenting symptom was facial swelling/pain (26.2%). The most common primary site was the nasal cavity (36.9%). Diffuse large B‐cell lymphoma was the most common subtype (46.4%), followed by extranodal NK/T‐cell lymphoma (17.9%). Chemotherapy was the most common treatment strategy (n = 59, 70.2%), followed by radiation therapy (n = 35, 41.7%) and immunotherapy (n = 24, 28.6%). Disease‐specific survival rates at 1, 5, and 10 years were 85.7%, 73.6%, and 58.6%, respectively. Eighteen patients (21.4%) developed recurrence. On multivariate analysis, higher ECOG score (p < 0.0001) and history of head and neck radiation (p = 0.048) were associated with worse survival. Younger age was associated with greater risk of recurrence (p = 0.022) and male sex was associated with more treatment side effects (p = 0.012).ConclusionThis is the largest multi‐institutional analysis of SL characteristics and outcomes. Our work suggests that, although disease control in the first 5 years is reasonable, 10‐year outcomes remain challenging. Further studies are needed to investigate new treatment paradigms and risk stratification.

AbstractIntroductionAn Alzheimer's disease (AD) dementia disease progression model was developed based on the integrated Alzheimer's Disease Rating Scale (iADRS).MethodsData from 3483 placebo participants in six AD trials were used to develop the disease progression model with NONMEM (version 7.4.2) and examined for mild cognitive impairment, and mild and moderate dementia due to AD.ResultsBaseline iADRS score was significantly influenced by AD symptomatic medication use, EXPEDITION2 enrollment (included moderate AD participants), age, and baseline Mini‐Mental State Examination (MMSE) score. Rate of disease progression increased across disease stage and was significantly influenced by AD medication use, age, and baseline MMSE score. Apolipoprotein E ε4 carrier status did not influence baseline iADRS score or disease progression.DiscussionThese results demonstrate a disease progression model describing the time course of the iADRS across the AD severity spectrum. This model can assist future clinical trials in study design optimization and treatment effect interpretation.Highlights
A disease progression model described the integrated Alzheimer's Disease Rating Scale (iADRS) time course in mild cognitive impairment to moderate Alzheimer's disease.
Using the linear regression model, iADRS scores can be calculated for Mini‐Mental State Examination scores.
Results can help optimize future clinical trial design and aid in understanding treatment effects.

AbstractDeveloping mixed‐anion semiconductors for solar fuel production has inspired extensive interest, but the nitrohalide‐based photocatalyst is still in shortage. Here we report a layered nitro‐halide β‐ZrNBr with a narrow band gap of ca. 2.3 eV and low defect density to exhibit multifunctionalities for photocatalytic water reduction, water oxidation and CO2 reduction under visible‐light irradiation. As confirmed by the results of electron paramagnetic resonance (EPR) and density functional theory (DFT) calculations, the formation of anion vacancies in the nitro‐halide photocatalyst was inhibited due to its relatively high formation energy. Furthermore, performance of β‐ZrNBr can be effectively promoted by a simple exfoliation into nanosheets to shorten the carrier transfer distance as well as to promote charge separation. Our work extends the territory of functional photocatalysts into the nitro‐halide, which opens a new avenue for fabricating efficient artificial photosynthesis.

AbstractFlexible and biocompatible metal peptide frameworks (MPFs)derived from short and ultra‐short peptides have been explored for the storage of greenhouse gases, molecular recognition, and chiral transformations. In addition to short flexible peptides, peptides with specifically folded conformations have recently been utilized to fabricate a variety of metal helix frameworks (MHFs). The secondary structures of the peptides govern the structure‐assembly relationship and thereby control the formation of three‐dimensional (3D)‐MHFs. Particularly, the hierarchical structural organization of peptide‐basedMHFshas not yet been discussed in detail. Here, we describe the recent progress of metal‐driven folded peptide assembly to construct 3D porous structures for use in future energy storage, chiral recognition, and biomedical applications, which could be envisioned as an alternative to the conventional metal‐organic frameworks (MOFs).

Published: November 2022

AbstractHydroboration of styrene or vinylcyclohexane with the IMes(C6F5)BH+ cation followed by deprotonation provided a convenient synthetic entry to the [B]=CHCH2R boraalkenes 9 a and 9 b. The in situ generated IMes(SCN)BH+ system reacted similarly with 1,1‐diphenylethene followed by deprotonation to give the isothiocyanato substituted boraalkene 9 c. The boraalkenes underwent [2+2] cycloaddition reactions with a small series of heterocumulenes to give the respective four‐membered heterocycles. The [B]=CHCH2R+CO2 cycloadducts 13 a and 13 b added the borane HB(C6F5)2 with cleavage of the central B−C σ‐bond. CS2 underwent an unusual reaction with the boraalkenes, namely insertion into the B=C bond with formation of the borylated dithioketene acetal under complete rupture of the strong B=C double bond. The intermediate dithiobora‐β‐lactone type intermediate was isolated in the case of the isothiocyanato‐boraalkene reaction and characterized by X‐ray diffraction.
Unsymmetrically Chlorinated Non‐Fused Electron Acceptor Leads to High‐Efficiency and Stable Organic Solar Cells

Published: November 2022

AbstractSearching the cost‐effective organic semiconductors is strongly needed in order to facilitate the practice of organic solar cells (OSCs), yet to be fulfilled. Herein, we have succeeded in developing two non‐fused ring electron acceptors (NFREAs), leading to the highest efficiency of 16.2 % for the NFREA derived OSCs. These OSCs exhibit the superior operational stabilities under one sun equivalent illumination without ultraviolet (UV) filtration. It is revealed that the modulation of halogen substituents on aromatic side chains, as the new structural tool to tune the intermolecular interaction and optoelectronic properties of acceptors, not only promotes the interlocked tic‐tac‐toe frame of three‐dimensional stacks in solid, but also improves charge dynamics of acceptors to enable high‐performance and stable OSCs.
