Published: May 2023

AbstractOrganic molecules with fluorescence‐phosphorescence dual‐emission have attracted significant attention for their potential applications in white organic light‐emitting diodes (WOLEDs). Herein, donor–accepter molecules, Mes*BA‐Cz and FXylBA‐Cz, are designed and synthesized, and the photoluminescence of these two compounds in solid state exhibits fluorescence‐phosphorescence dual‐emission. Through the single crystal study, the phosphorescent emission is mainly caused by the molecular stacking in the crystalline state, which is beneficial for aggregation‐induced intersystem crossing. Dual emission behavior further caused the mechanochromism of the two compounds, with emission color changed between amorphous and crystalline state. White light photoluminescence with CIE coordinates of (0.33, 0.34) is achieved by doping FXylBA‐Cz in the poly (methyl methacrylate) film. Furthermore, a WOLED based on FXylBA‐Cz is manufactured with CIE coordinates of (0.31, 0.33), and the external quantum efficiency (EQE) reached 0.49%.

AbstractA series of copper complexes was synthesized and studied as photocatalysts for the chlorosulfonylation of olefins. Featuring a tetradentate ligand consisting of one amino quinoline and two methyl pyridine moieties, the resulting Cu(II)‐complex is effective under visible light irradiation to add sulfonyl chlorides to alkenes and alkynes, including unactivated aliphatic olefins. A weak base additive such as Na2CO3 prevents catalyst poisoning, resulting in an improvement of reaction yields and catalyst lifetime. A broad scope of sulfonyl chlorides and alkenes/alkynes as coupling partners are amenable for the title process, including examples previously reported unsuccessful with established copper‐based photocatalysts.

AbstractLithium–sulfur (Li–S) batteries are one of the most competitive candidates for high‐energy‐density batteries. However, the high energy density and high reactivity of the lithium anode and sulfur cathode make the safety issues of Li–S batteries particularly prominent. Herein, an early warning strategy for the short circuits in Li–S batteries is explored by integrating an in‐plane electron‐conductive separator. The internal short circuits caused by lithium dendrites or manufacturing defects can be quickly and accurately predicted before catastrophic thermal runaway, with enough time to take rescue measures. The separator with high thermal conductivity also facilitates the heat dissipation of the cell, thus reducing the risk of thermal runaway under abuse. The fast and reliable early warning strategy based on the in‐plane electron‐conductive separator builds the Great Wall of active defense against inherently unsafe Li–S batteries.

AbstractThis work for the first time develops and employs the novel cerium‐praseodymium‐neodymium oxide co‐doped tin oxide (Ln3+(Ce3+‐Pr3+‐Nd3+):SnO2) system for varied energy applications including electro‐catalytic, super‐capacitive, and photovoltaic conversion potential. The outstanding optical, compositional, crystalline, and morphological aspects of the synthesized material express its effectiveness for energy related micro‐electrochemical applications. Bandgap narrowing due to lanthanide doping and acquiring cassiterite crystalline phase results in the auspicious output. O2 and H2 evolution of the developed electro‐catalyst expresses superior energy production with lower overpotential values of 95 mV for O2 and 131 mV toward H2. Fabricated electrode expresses an impressive charge storage potential with the specific capacitance of 151.62 F g−1. Also, this electrode has an extended service life for 100 min showing its ultra‐durability for commercial applications. Ln3+(Ce3+‐Pr3+‐Nd3+):SnO2 is used as an electron transport layer in the cesium based solar cells with the power conversion efficiency of 12.49%, short circuit current of 19.63 mA cm−1, and open circuit voltage of 1.2 V under artificial sun with negligible hysteresis. Ln3+(Ce3+‐Pr3+‐Nd3+):SnO2 is an effective material with the perfect bandgap tuned exceeding the pristine material for diverse energy applications marked by profound sustainability and economic viability.

AbstractThe severe capacity loss of spinel LiMn2O4 (LMO) limits the utility of this otherwise promising lithium ion battery cathode material. One of the strategies to mitigate capacity fade is applying a coating on LMO particle surfaces. While this approach yields promising results, there is limited understanding of mechanisms whereby coatings improve LMO capacity retention. Herein, the effects of a new protective coating material, La0.5Sr0.5CoO3 (LSCO), in a thin‐film battery geometry that is amenable to fundamental studies of electrode processes, are reported. RF sputtering deposition is used to produce high quality 25–100 nm LMO cathodes on Al2O3 substrates with an intervening Pt/Ti back‐side contact layer. Cycling of the un‐coated cathodes results in capacity loss of 18% over 300 cycles. Adding a 2 nm LSCO layer reduces the capacity loss to 3%. While this may be due in part to reduced Mn dissolution, scanning transmission electron microscopy results indicate that the coating helps to preserve crystallinity and reduce lattice structure distortion due to inhibited formation of defect tetragonal spinel. Three‐electrode electrochemical impedance spectroscopy results reveal that the LSCO coating increases charge transfer and ohmic resistances, but the increases are generally too small to significantly impact cell performance even at high C‐rates.

Published: May 2023

AbstractTwo‐dimensional transition metal dichalcogenides (2D TMDs) present promising applications in various fields such as electronics, optoelectronics, memory devices, batteries, superconductors, and hydrogen evolution reactions due to their regulable energy band structures and unique properties. For emerging spintronics applications, materials with excellent room‐temperature ferromagnetism are required. Although most transition metal compounds do not possess room‐temperature ferromagnetism on their own, they are widely modified by researchers using the emerging strategies to engineer or modulate their intrinsic properties. This paper reviews recent enhancement approaches to induce magnetism in 2D TMDs, mainly using doping, vacancy defects, composite of heterostructures, phase modulation, and adsorption, and also by electron irradiation induction, O plasma treatment, etc. On this basis, the produced effects of these methods for the introduction of magnetism into 2D TMDs are compressively summarized and constructively discussed. For perspective, research on magnetic doping techniques for 2D TMDs materials should be directed toward more reliable and efficient directions, such as exploring advanced design strategies to combine dilute magnetic semiconductors, antiferromagnetic semiconductors, and superconductors to develop new types of heterojunctions; and advancing experimentation strategies to fabricate the designed materials and enable their functionalities with simultaneously pursuing the upscalable growth methods for high‐quality monolayers to multilayers.

AbstractWater adsorption‐driven heat transfer (AHT) technology has emerged as a promising solution to address crisis of the global energy consumption and environmental pollution of current heating and cooling processes. Hydrophilicity of water adsorbents plays a decisive role in these applications. This work reports an easy, green, and inexpensive approach to tuning the hydrophilicity of metal–organic frameworks (MOFs) by incorporating mixed linkers, isophthalic acid (IPA), and 3,5‐pyridinedicarboxylic acid (PYDC), with various ratios in a series of Al−xIPA‐(100−x)PYDC (x: feeding ratio of IPA) MOFs. The designed mixed‐linkers MOFs show a variation of hydrophilicity along the fraction of the linkers. Representative compounds with a proportional mixed linker ratio denoted as KMF‐2, exhibit an S‐shaped isotherm, an excellent coefficient of performance of 0.75 (cooling) and 1.66 (heating) achieved with low driving temperature below 70 °C which offers capability to employ solar or industrial waste heat, remarkable volumetric specific energy capacity (235 kWh m−3) and heat‐storage capacity (330 kWh m−3). The superiority of KMF‐2 to IPA or PYDC‐containing single‐linker MOFs (CAU‐10‐H and CAU‐10pydc, respectively) and most of benchmark adsorbents illustrate the effectiveness of the mixed‐linker strategy to design AHT adsorbents with promising performance.

Published: May 2023

AbstractMost of the current bioadhesives cannot perform well on bleeding tissues while postoperative adhesion is a general but serious clinical issue. Here, a three‐layer biodegradable Janus tissue patch (J‐TP) that is able to simultaneously enable efficient closure of bleeding wounds with significantly promoted clotting ability and suppressed postoperative adhesion of tissues is reported. A dry adhesive hydrogel bottom layer of the J‐TP can form rapid (within 15 s) and strong (tensile strength up to 98 kPa) adhesion to bleeding/wet tissues with high bursting pressure (about 312.5 mmHg on a sealed porcine skin) through hydrogen binding and covalent conjugation between the carboxyl & N‐hydroxy succinimide (NHS) groups of hydrogel and the primary amine groups of tissues, while the phosphonic motifs can significantly reduce blood loss (by 81% on a rat bleeding liver model) of bleeding wounds. A thin polylactic acid (PLA) middle layer can improve the tensile strength (by 132%) of the J‐TP in wet conditions while the grafted zwitterionic polymers can effectively prevent postoperative tissue adhesion and inflammatory reaction. This J‐TP may be a promising tissue patch to assist the clinical treatment of injured bleeding tissues with inhibited postoperative adhesion.
A Quasisolid Electrolyte Thermogalvanic Cell by Using Sand Grains
Authors: Han Kui , Xie Li 
Published: May 2023

AbstractThermogalvanic cells (TGCs) can convert low‐grade heat into electric energy. Currently, Carnot efficiency of the P‐type TGC can reach higher than 11%, but the TGC's commercialization is still limited due to the low Carnot efficiency of the N‐type TGC. In this paper, new TGCs are reported, and they are made of desert sand grains mixed with the Cu(NO₃)₂ aqueous electrolyte, named as QS‐Cu‐TGCs, the thermoelectric performance of which is investigated. It is found that although sand grains are common, widely seen in the desert, the Carnot efficiency of such N‐type QS‐Cu‐TGCs is quite high, about 4%, with the Seebeck coefficient of 8.4 mV K−1, driven by the temperature difference 12.1 K between two electrodes, in an environment below 373 K.

Published: May 2023

AbstractLightweight carbonized wood has a hierarchically 3D porous framework and orthotropic channels along the growth direction, which demonstrate great potential for multifunctional electronic materials. Herein, carbonized wood with outstanding electromagnetic interference (EMI) shielding effectiveness (SE), high thermal conductivity, and excellent Joule heating property is fabricated. It also exhibits a highly anisotropic EMI shielding performance in the cross‐ and tangential‐sections. In the tangential‐section, the shielding performance of carbonized wood is tuned by monitoring the angle between the wood grain and the electric field vibration direction of the electromagnetic waves, and the SE value ranges from 29 to 77 dB when the angle changes from 90° to 0°. Benefiting from the high SE obtained from structural optimization and the low density, carbonized balsa wood displays a high SSE (the ratio of SE to density) and SSE/t (the ratio of SSE to thickness) of 1069 dB cm3 g−1 and 3263 dB cm2 g−1, respectively. The thermal conductivity of carbonized wood is also angle‐dependent, which ranges from 0.865 to 1.897 W m−1 K−1. With the improvement in thermal conductivity, carbonized wood can be used as a heat sink material. Meanwhile, excellent Joule heating properties are achieved due to the effective conductive pathway in carbonized wood.
Uncovering the Effect of Solid Electrolyte Interphase on Ion Desolvation for Rational Interface Design in Li‐Ion Batteries

Published: May 2023

AbstractThe conventional knowledge of solid electrolyte interphases (SEIs) is limited to their ionic conductive and electron‐insulating properties. The solvation structure regulation in the new‐concept electrolytes always leads to the regulated SEI, resulting in the improvement of ion desolvation kinetics. However, the linkage between the improved kinetics and the regulated SEl remains unconnected at the atomic level. Herein, this work proposes that the SEI can function more by facilitating ion desolvation. Using quantum chemistry calculations, this work explores the ion desolvation processes with and without SEI. It is found the accelerated ion desolvation in the new‐concept electrolytes is directly attributed to the SEI rather than the regulated solvation structure. Based on the recognition of SEI's role, this work proposes an SEI‐aided ion desolvation model. This study bridges the SEI and battery kinetics at the atomic scale and redefines the functions of SEI, which are expected to steer the electrolyte design in batteries.
Heterogeneous impacts of GlobalGAP adoption on net income in small‐scale pineapple farming in Ghana: Does farm size matter?
Authors: Annor Prince B. , Kaitibie Simeon , Lyne Michael C. 
Published: May 2023

AbstractAdoption of Global Good Agricultural Practices (GlobalGAP) improves food quality and safety along fresh produce value chains. However, adoption rates have been low among small‐scale pineapple farmers in Ghana, but with possible heterogeneous responses due to farm size economies. This study estimates the impact of GlobalGAP adoption on net incomes earned by small‐scale pineapple farmers in Ghana's main producing region, and examines size‐induced heterogeneous effects of adoption on income. Household and farm‐level data gathered from 546 small‐scale farmers were analyzed using a two‐stage regression model to estimate the impact of GlobalGAP adoption on per hectare pineapple net income. Robustness of the results was checked by re‐estimating the two‐stage model using a maximum likelihood extended regression model. GlobalGAP adoption reduced net income on small farms growing less than 1 ha of pineapples, but increased net income on small farms growing more than 1 ha of pineapples. We conclude that GlobalGAP adoption and farm size are not independent determinants of profitability, and recommend that extension and other interventions intended to promote GlobalGAP adoption among pineapple farmers in Ghana should be targeted at those who are willing and able to grow more than 1 ha of pineapples [EconLit Citations: Q16, Q13].

Published: May 2023

AbstractHydrogen atom transfer (HAT) is one of the important class of radical reactions. Although extensive research into this elementary step has resulted in the discovery of many compounds capable of functioning as HAT reagents, synthetic methods available to control the stereoselectivity of the HAT process remains challenging. This mini review outlines how small molecule chiral HAT reagents and catalysts were used to achieve stereoselectivity (diastereoselectivity and enantioselectivity) in free radical reactions. The review also focuses on the recent surge in photoenzymatic catalysis to achieve efficient HAT reactions.

AbstractINTRODUCTIONRecent genome‐wide association studies identified new dementia‐associated variants. We assessed the performance of updated polygenic risk scores (PRSs) using these variants in an independent cohort.METHODSWe used Cox models and area under the curve (AUC) to validate new PRSs (PRS‐83SNP, PRS‐SBayesR, and PRS‐CS) compared with an older PRS‐23SNP in 12,031 initially‐healthy participants ≥70 years of age. Dementia was rigorously adjudicated according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM‐IV) criteria.RESULTSPRS‐83SNP, PRS‐SBayesR, and PRS‐CS were associated with incident dementia, with fully adjusted (including apolipoprotein E [APOE] ε4) hazard ratios per standard deviation (SD) of 1.35 (1.23–1.47), 1.37 (1.25–1.50), and 1.42 (1.30–1.56), respectively. The AUC of a model containing conventional/non‐genetic factors and APOE was 74.7%. This was improved to 75.7% (p = 0.007), 76% (p = 0.004), and 76.1% (p = 0.003) with addition of PRS‐83SNP, PRS‐SBayesR, and PRS‐CS, respectively. The PRS‐23SNP did not improve AUC (74.7%, p = 0.95).CONCLUSIONNew PRSs for dementia significantly improve risk‐prediction performance, but still account for less risk than APOE genotype overall.

BackgroundThe association between markers of vitamin B12 status and cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease (AD), which precede cognitive impairment, has been investigated by only a few small studies and results have been inconsistent.AimThe aim of this study was to investigate the associations of vitamin B12‐related markers with CSF biomarkers of AD and cognitive performance.MethodsData included 462 patients aged 40 to 94 years referred to the Memory Clinic of the Ulm University Hospital, Ulm, Germany. Vitamin B12, holotranscobalamin (HoloTC), homocysteine (tHcy), and methylmalonic acid (MMA) have been measured. CSF values of amyloid β42 (Aβ42) and total‐tau have been assessed in 227 participants. CERAD battery was administered to examine the cognitive status, and different domains were derived. Regression models were used to investigate the associations.ResultsIn the multi‐adjusted model, higher levels of MMA were associated with raised CSF total‐tau values: the odds ratios (ORs) 95% confidence intervals (CIs) were 3.25 (95% CI = 1.35–7.76) for the highest quartile of MMA compared to the lowest. Furthermore, moderately increased MMA were related to lower Aβ42 levels: the ORs and 95% CIs were 3.06 (95% CI = 1.22–7.67) for the third quartile of MMA compared to the lowest. All B12 indicators except B12 itself were related to several cognitive domains, such as episodic memory and executive functioning.ConclusionsMarkers of vitamin B12 may be independent predictors of CSF biomarkers of AD and cognitive functioning, with MMA showing the most consistent effects. Randomized controlled trials are needed to determine the importance of vitamin B12 supplementation on slowing structural brain changes and cognitive decline. ANN NEUROL 2023;94:223–231

ObjectiveVGF is proposed as a potential therapeutic target for Alzheimer's (AD) and other neurodegenerative conditions. The cell‐type specific and, separately, peptide specific associations of VGF with pathologic and cognitive outcomes remain largely unknown. We leveraged gene expression and protein data from the human neocortex and investigated the VGF associations with common neuropathologies and late‐life cognitive decline.MethodsCommunity‐dwelling older adults were followed every year, died, and underwent brain autopsy. Cognitive decline was captured via annual cognitive testing. Common neurodegenerative and cerebrovascular conditions were assessed during neuropathologic evaluations. Bulk brain RNASeq and targeted proteomics analyses were conducted using frozen tissues from dorsolateral prefrontal cortex of 1,020 individuals. Cell‐type specific gene expressions were quantified in a subsample (N = 424) following single nuclei RNASeq analysis from the same cortex.ResultsThe bulk brain VGF gene expression was primarily associated with AD and Lewy bodies. The VGF gene association with cognitive decline was in part accounted for by neuropathologies. Similar associations were observed for the VGF protein. Cell‐type specific analyses revealed that, while VGF was differentially expressed in most major cell types in the cortex, its association with neuropathologies and cognitive decline was restricted to the neuronal cells. Further, the peptide fragments across the VGF polypeptide resembled each other in relation to neuropathologies and cognitive decline.InterpretationMultiple pathways link VGF to cognitive health in older age, including neurodegeneration. The VGF gene functions primarily in neuronal cells and its protein associations with pathologic and cognitive outcomes do not map to a specific peptide. ANN NEUROL 2023;94:232–244
