AbstractPerovskite solar cells (PSCs) based on formamidinium lead iodide (FAPbI3) have demonstrated the highest power conversion efficiencies. Typically fabricated through solution‐processing, FAPbI3 films necessitate intricate crystallization control to avoid the formation of a more stable non‐perovskite phase. Magnetron sputtering, an effective solvent‐free technique, has gained attention for producing large‐area perovskite films. Here, a novel approach to create high‐quality FAPbI3‐based perovskite thin films by employing magnetron sputtering is presented. Specifically, a mechanosynthesized blend of (FA1‐xMAx)Pb(I1‐xBrx)3 (MA = methylammonium) is used as a single‐source target for sputtering, and a post‐annealing transforms various phases in the initial deposited film into coherent FAPbI3‐based films with an ultra‐long and controlled crystallization process. Despite minimal residual MABr after post‐annealing, its presence is crucial in the formation of perovskite film, as evidenced by a distinct solid‐state phase transformation process is presented. A comprehensive investigation of the films' structural, compositional, and optical properties, with respect to varying MABr doping ratios, reveals details of perovskite phase development and the pivotal influence of MABr. PSCs fabricated with the optimized films display a substantial increase in the power conversion efficiency, reaching 20.1%. These results underscore the potential of combining magnetron sputtering and post‐annealing in the scalable production of high‐efficiency PSCs.

AbstractBiodegradable polymers such as polylactic‐co‐glycolic acids (PLGA) are used for various implantable devices such as tissue scaffolds, drug delivery devices, and biosensors in different forms. However, high‐resolution patterning of biodegradable polymers on implantable devices has not been explored much yet. While electrohydrodynamic printing (EHD) can achieve high‐resolution printing compared to other printing methods, EHD printing of PLGA solutions is rarely attempted due to unstable printing. Such printing instability originates from the volatile nature of PLGA inks, and it causes nozzle clogging or change of ink conditions during printing. Here, PLGA ink formulation and a voltage input profile are studied for stable and high‐resolution EHD printing. Addition of glycerol at an optimal ratio as well as the control of voltage pulse shape strongly influenced both the stability and resolution of EHD printing of PLGA patterns. With the optimized inks and voltage inputs, stable printing of PLGA micropatterns down to 5 µm is achieved on both conductive and insulating surfaces for controlled drug release. Furthermore, use of a ring type electrode allows for EHD printing of PLGA micropatterns on 3D surfaces of PLLA tubes and stent struts.

AbstractWireless sensor networks play a significant role in various fields, and it is promising to construct a totally self‐powered wireless sensor network by harvesting unused mechanical vibration energy. Here, a magnetic mass‐enhanced triboelectric‐electromagnetic hybrid nanogenerator (MM‐HNG) is proposed for harvesting mechanical vibration energy. The additional magnets generate magnetic fields for electromagnetic power generation. As an additional mass effectively increases the membrane's amplitude, thereby enhancing the output performance of the MM‐HNG. The peak power density of TENG in the MM‐HNG reaches 380.4 W m−3, while the peak power density of EMG achieves 736 W m−3, which can charge a 0.1 F capacitor rapidly. In addition, a totally self‐powered wireless sensing system is constructed, with the integrated microcontroller unit (MCU), which detects and processes various sensing parameters and controls wireless transmission. The system features rapid transmission speeds and an extensive transmission range (up to 1 km), and its effectiveness has been validated in a practical application aboard an actual ship. The results illustrate the MM‐HNG's broad applicability across various Internet of Things (IoT) scenarios, including smart machinery, smart transportation, and smart factories.

AbstractCarbon dots (CDs) possess intrinsically broad emission spectra, making them suitable for modulating high‐quality white light‐emitting diodes (WLEDs). However, the chief technical challenge in applying CDs to WLEDs is the aggregation‐caused quenching (ACQ) effect. A common solution is polymer post‐modification on the surface of CDs, which is a low‐yield, hard‐to‐purified, and complicated process. Herein, polymerized CDs with broad emission (full width at half maxima, FWHM = 187 nm) are synthesized via a one‐step solvothermal method. The obtained polymerized CDs display excellent solution‐processed and film‐forming capabilities, with absolute photoluminescence quantum yield as high as 4.7% in thin film state, creating a firm foundation for assembling solution‐processed WLEDs. Moreover, the polymerization steps of CDs are analyzed and described in detail. The polymer chains prevent ACQ and create new energy levels, resulting in the broad emission of CDs in an aggregated state. Subsequently, WLEDs are fabricated using polymerized CDs as the single active emitting material. The optimal device achieves the maximum brightness of 337.50 cd m−2 and FWHM of 242 nm, covering nearly the entire visible spectral window. The results present a new approach to obtaining polymerized CDs and further fabricating WLED with a straightforward, cost‐effective method.

Published: July 2024

AbstractSome creatures have periodic nanostructures and chromophores in their flexible organs that allow them to control the color and shape of their skin. Artificial photonic structures that can mimic the aforementioned ability of these natural structures are researched extensively. In this study, polydopamine‐incorporated core–interlayer–shell (CIS‐PDA) nanoparticles capable of shape reconfiguration and expressing vivid structural colors are designed. These nanoparticles can be readily assembled to produce colloidal photonic crystals (CPhCs) and can exhibit vivid structural colors by virtue of their light‐absorbing capability. Soft CPhC films prepared with these nanoparticles undergo stable elastic deformation at 15% strain and exhibit mechanochromic properties. Specifically, the PDA in the CIS nanoparticles can absorb broadband light and exhibit a photothermal effect resembling that of melanosomes in living organisms, which enables self‐healing between multiple CPhC films. Due to their favorable properties, the CPhC films prepared in this study represent promising photothermally reconfigurable photonic materials. Moreover, arbitrarily shaped 2D or 3D surfaces are conformally coated with the films via microimprinting or vacuum wrapping, courtesy of the reconfigurability of these films. These findings suggest that CPhC films prepared with CIS‐PDA nanoparticles can be used as form‐free mechanochromic strain sensors and nonfading optical films for industrial products.

AbstractIn synthetic carbohydrate chemistry, the modification of glycosyl radicals pathway stands as a central area of focus. The radical‐based reactions often demonstrate remarkable compatibility with various functional groups owing to the mild initiation conditions. In particular, the identification of novel glycosyl radical precursors, combined with advanced reaction techniques, has substantially broadened the scope of glycosyl compound synthesis. Despite the presence of versatile donors, the synthesis of noble donors is still addressed as a synthetic need and challenges associated with sugar chemistry. Currently, a new class of glycosyl radical precursors has been developed which enables the production of C‐, S‐, O‐, and N‐glycosides efficiently. In this light, we highlight strategies towards bench‐stable glycosyl sulfoxides, sulphone, and sulfite donors that can enable the site‐, regio‐ and stereoselective transformation of protected or naked sugar synthons in synthetic carbohydrate chemistry. Here, this review article covers the recent developments in the selective glycosyl radical diversification such as glycosyl alkylation, arylation, alkenylation, sulfuration, C−H activation, and DNA conjugation via the bench‐stable donors along with mechanistic aspects, challenges, and future directions.

AbstractAs plastics become more ubiquitous, their impact on the environment and on human health cannot be overlooked. Once generated, micro‐ and nano‐plastics end‐up in the environment, causing widespread health and environmental risks. This is a significant environmental problem given the minuscule sizes of microplastics, and therefore warrants further investigation. This study presents a comprehensive review of the ecotoxicology of microplastics and methods for their degradation and decomposition besides discussing the fate and transport processes, recent progress, emerging strategies, challenges and potential future directions. The authors carefully evaluate the processes through which microplastics cause harm, from molecular interactions in species, to ecological impacts, and end with advances in microplastic biodegradation. Different kinds of microplastics found in the environment include polyethylene, polystyrene, polypropylene, polyvinyl chloride, polycarbonate, polyurethane, polypropylene, and polyethylene terephthalate. Analysis of microbial and enzymatic decomposition provides several swelling mitigation strategies designed to reduce environmental threats. In‐depth investigations of microplastic ecotoxicity and biodegradation are being facilitated by interdisciplinary proposals in the areas of nanotechnology, new analytical methods, and synthetic biology. The extensive study helps understand microplastics comprehensively which in‐turn ensures informed actions to mitigate the challenge of the environmental impact of microplastics for sustainable future.

AbstractMicrometer‐sized silicon monoxide (SiO) is regarded as a high‐capacity anode material with great potential for lithium ion batteries (LIBs). However, the problems of low initial Coulombic efficiency (ICE), poor electrical conductivity, and large volume change of SiO inevitably impede further application. Herein, the vacuum thermal reduced SiOx with amorphous AlPO4 and carbon double‐coating layers is used as the ideal anode material in LIBs. The vacuum thermal reduction at low temperature forms fine silicon grains in the internal particles and maintains the external integrity of SiOx particles, contributing to mitigation of the stress intensification and the subsequent design of multifunctional coating. Meanwhile, the innovative introduction of the multifunctional amorphous AlPO4 layer not only improves the ion/electron conduction properties to ensure the fast reversible reaction but also provides a robust protective layer with stable physicochemical characteristics and inhibits the volume expansion effect. The sample of SiOx anode shows an ICE up to 87.6% and a stable cycling of 200 cycles at 1 A g−1 with an initial specific capacity of 1775.8 mAh g−1. In addition, the assembled pouch battery of 1.8 Ah can also ensure a cycling life of over 150 cycles, demonstrating a promising prospect of this optimized micrometer‐sized SiOx anode material for industrial applications.

AbstractFacilitating (002)‐textured zinc growth is crucial for achieving dendrite‐free zinc deposition in zinc‐ion batteries. Electrolyte engineering holds promise in directing zinc electrodeposition toward this desired orientation. However, despite the (002) plane's lower surface energy compared to other facets, it remains unclear why this plane does not dominate zinc crystal faces during electrodeposition under normal conditions. This knowledge gap underscores the need to better understand zinc electrodeposition behaviors and the influence of electrolyte compositions on its crystallographic texture. This study explores different tetraazamacrocycle derivatives as electrolyte additives. It reveals that achieving (002)‐textured zinc deposition is not solely dictated by thermodynamic equilibrium but also significantly influenced by interface dynamics. In typical ZnSO4 electrolytes, imbalanced kinetics among reduction, ion diffusion, and adatom diffusion processes lead to electroconvection and disorderly zinc accumulation, hindering proper zinc growth. In contrast, introducing specific tetraazamacrocycle derivative in the electrolyte regulates reduction rate, enhances limiting current density, and expedites adatom diffusion, mitigating hydrodynamic instability and dendrite growth. This regulation restores the thermodynamically favorable flat (002)‐textured zinc deposition, extending the zinc anode's lifespan to 1800 h at 5 mA cm−2 and 5 mAh cm−2, enabling the fabrication of a high‐performance zinc ion hybrid capacitor prototype capable of stable operation for 40 000 cycles.

Published: July 2024

AbstractSemi‐transparent perovskite solar cells (ST‐PSCs) are promising for their application in building integrated photovoltaics (BIPVs). For BIPVs, a light utilization efficiency (LUE) > 2.5 is required which is multiplication of average visible transmittance (AVT) and power conversion efficiency (PCE). Generally, semitransparency is achieved by reducing film thickness which increases AVT but decreases PCE resulting in lower LUE. Here, an interface engineering strategy is employed on a wide bandgap perovskite thin absorber layer to increase PCE and LUE. The study employs three different alkylamine hydrochlorides molecules with varied alkyl chain length, viz., 2‐chloroethylamine‐hydrochloride, 3‐chloropropylamine‐hydrochloride, and 4‐chlorobutyalamine‐hydrochloride at perovskite/electron transport layer (ETL) interface and investigates their effect on perovskite crystallization. Further, it is demonstrated that 4‐chlorobutyalamine‐hydrochloride can strongly interact with perovskite and suppress non‐radiative recombination facilitating charge transport at the perovskite/ETL interface. Devices post‐treated with 4‐chlorobutyalamine‐hydrochloride interfacial layer, demonstrate a higher LUE of 3.45% (PCE 14.11%) and AVT of ≈25% (400–800 nm), with Voc of 1.23 V. Moreover, the unencapsulated devices retain ≈89% of the initial efficiency after storage for 1500 h under a relative humidity of ≈35–40%. This study provides an efficient approach to improve LUE and stability of ST‐PSCs for the application in energy‐efficient smart windows.

AbstractA series of triphenylamine‐quinoxaline donor‐acceptor (bipolar) compounds (TPA‐QH, TPA‐QMe, TPA‐QCOOH and TPA‐QNO2) with different substituents were synthesized and investigated their fluorescence properties, including stimuli‐induced fluorescence responses in solution and the solid‐state. Single crystal structural analysis revealed non‐planar molecular conformation, substituent controlled intermolecular interactions and molecular packing in the crystal lattice. TPA‐QH, TPA‐QMe, TPA‐QCOOH and TPA‐QNO2 showed tunable solid‐state emission from green to red. TPA‐QH showed strong fluorescence at 487 nm (quantum yield (Φf)=28.3 %) whereas NO2 substituted TPA‐QNO2 exhibited relatively weak fluorescence at 610 nm (Φf=4.3 %). Density functional theoretical (DFT) calculations also indicated reduction of optical bandgap with substituting electron withdrawing group. The donor‐acceptor structure with intramolecular charge transfer (ICT) resulted solvent polarity dependent fluorescence tuning. The presence of acid responsive quinoxaline group was utilized to demonstrate pH‐responsive fluorescence switching and dual state fluorescence was utilized for fabricating rewritable fluorescent platform. Thus, the present study provides a structural insight to develop dual state emissive triphenylamine–quinoxaline based bipolar materials for optoelectronic applications.

AbstractINTRODUCTIONPlasma has been proposed as an alternative to cerebrospinal fluid (CSF) for measuring Alzheimer's disease (AD) biomarkers, but no studies have analyzed in detail which biofluid is more informative for genetics studies of AD.METHODEleven proteins associated with AD (α‐synuclein, apolipoprotein E [apoE], CLU, GFAP, GRN, NfL, NRGN, SNAP‐25, TREM2, VILIP‐1, YKL‐40) were assessed in plasma (n = 2317) and CSF (n = 3107). Both plasma and CSF genome‐wide association study (GWAS) analyses were performed for each protein, followed by functional annotation. Additional characterization for each biomarker included calculation of correlations and predictive power.RESULTSEighteen plasma protein quantitative train loci (pQTLs) associated with 10 proteins and 16 CSF pQTLs associated with 9 proteins were identified. Plasma and CSF shared some genetic loci, but protein levels between tissues correlated weakly. CSF protein levels better associated with AD compared to plasma.DISCUSSIONThe present results indicate that CSF is more informative than plasma for genetic studies in AD.Highlights
The identification of novel protein quantitative trait loci (pQTLs) in both plasma and cerebrospinal fluid (CSF).
Plasma and CSF levels of neurodegeneration‐related proteins correlated weakly.
CSF is more informative than plasma for genetic studies of Alzheimer's disease (AD).
Neurofilament light (NfL), triggering receptor expressed on myeloid cells 2 (TREM2), and chitinase‐3‐like protein 1 (YKL‐40) tend to show relatively strong inter‐tissue associations.

ObjectiveWe aimed to elucidate the pathogenic mechanisms underlying autosomal dominant adult‐onset demyelinating leukodystrophy (ADLD), and to understand the genotype/phenotype correlation of structural variants (SVs) in the LMNB1 locus.BackgroundSince the discovery of 3D genome architectures and topologically associating domains (TADs), new pathomechanisms have been postulated for SVs, regardless of gene dosage changes. ADLD is a rare genetic disease associated with duplications (classical ADLD) or noncoding deletions (atypical ADLD) in the LMNB1 locus.MethodsHigh‐throughput chromosome conformation capture, RNA sequencing, histopathological analyses of postmortem brain tissues, and clinical and neuroradiological investigations were performed.ResultsWe collected data from >20 families worldwide carrying SVs in the LMNB1 locus and reported strong clinical variability, even among patients carrying duplications of the entire LMNB1 gene, ranging from classical and atypical ADLD to asymptomatic carriers. We showed that patients with classic ADLD always carried intra‐TAD duplications, resulting in a simple gene dose gain. Atypical ADLD was caused by LMNB1 forebrain‐specific misexpression due to inter‐TAD deletions or duplications. The inter‐TAD duplication, which extends centromerically and crosses the 2 TAD boundaries, did not cause ADLD. Our results provide evidence that astrocytes are key players in ADLD pathology.InterpretationOur study sheds light on the 3D genome and TAD structural changes associated with SVs in the LMNB1 locus, and shows that a duplication encompassing LMNB1 is not sufficient per se to diagnose ADLD, thereby strongly affecting genetic counseling. Our study supports breaking TADs as an emerging pathogenic mechanism that should be considered when studying brain diseases. ANN NEUROL 2024;96:855–870
