High efficiency and stable solid-state fiber dye-sensitized solar cells obtained using TiO_2 photoanodes enhanced with metal organic frameworks

Solid-state fiber dye-sensitized solar cells (SS-FDSSCs) have been the subject of intensive attention and development in recent years. Although this field is only in its infancy, metal-organic frameworks (MOFs) are one such material that has been utilized to further improve the power conversion efficiency of solar cells. In this study, MOF-integrated DSSCs were shown to have potential in the development of solar cell devices with efficiency comparable to or better than that of conventional solar cells. The power conversion efficiency (PCE) of SS-FDSSCs was improved by embedding MOF-801 into a mesoporous-TiO_2 (mp-TiO_2) layer, which was used as a photoanode in SS-FDSSCs, which are inherently flexible. The PCE of the MOF-integrated SS-FDSSCs was 6.50%, which is comparable to that of the reference devices (4.19%). The MOF-801 enhanced SS-FDSSCs decreased the series resistance (R_s) value, resulting in effective electron extraction with improved short-circuit current density (J_(SC)), while also increasing the shunt resistance (R_(sh)) value to prevent the recombination of photo-induced electrons. The result is an improved fill factor and, consequently, a higher value for the PCE.
POE enhanced stabilities of CsPbX_3 (X = Br, I) perovskite and their white LED application

Perovskite has received extensive attention due to its excellent properties, just like photoelectric, while the instability has always troubled us to the wide application of perovskite materials. Herein, we proposed to use SiO_2 and POE to encapsulate perovskite nanocrystals (PNCs). In this work, we have successfully prepared a series of perovskite composite materials and films with different concentration ratios. Due to the protection of POE, the luminous intensity of CsPbBr_3@POE composite film remained above 90% after stayed in the water for 42 days. The lead concentration of CsPbBr_3@POE composite film was 0.8 lg/mL after 48 h of immersing in deionized water. Namely, packaging PNCs in POE could effectively prevent Pb from overflowing reduce Pb pollution. Besides, the composite films showed a wide colour gamut with 117% of NTSC colour gamut, which shows that this composite material has a development prospect in the WLED field.
Surface functionalized Pt/SnNb_2O_6 nanosheets for visible-light-driven the precise hydrogenation of furfural to furfuryl alcohol

Photocatalytic upgrading of renewable biomass is a promising way to relieve energy crisis and environmental pollution.However,low photocatalytic efficiency and uncontrollable selectivity still limit its development.Herein,ultrathin SnNb_2O_6 nanosheets with high dispersed Pt nanoparticles (Pt/SN) were successfully developed as an efficient photocatalyst for the precise hydrogenation of furfural (FUR) to furfuryl alcohol (FOL) under visible light irradiation and exhibited the high conversion of FUR (99.9%) with the high selectivity for FOL (99.9%).It was revealed that SN with only 4.1 nm thickness possess good separation ability of photo-generated carriers and abundant surface Lewis acid sites (Nb~(5+)) which would selectively chemisorb and activate FUR molecules via the Nb..O = C coordination.Meanwhile,Pt nanoparticles would gather photo-generated electrons for greatly promoting the generation of active H species to support the hydrogenation of FUR to FOL.The synergistic effects between SnNb_2O_6 nanosheets and Pt nanoparticles remarkably facilitate the photocatalytic performance for hydrogenation.This work not only confirms the great potential of ultrathin nanosheet photocatalyst with functional metal sites for precise upgrading of biomass but also provides an in-depth view to understand the surface/interface interaction between reactant molecules and surface sites of a photocatalyst.
In-situ growth of CoNi bimetal anchored on carbon nanoparticle/nanotube hybrid for boosting rechargeable Zn-air battery

Exploring highly efficient non-precious metal based catalysts for bifunctional oxygen electrode is crucial for rechargeable metal-air batteries.In this study,with MOFs as precursors,a facile coprecipitation method is designed to realize in-situ growth of the CoNi anchored carbon nanoparticle/nanotube (CoNi/N-CNN) hybrid,which can achieve the simultaneous maximum exposure of both oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) active centers.Benefiting from the unique structure,the CoNi/N-CNN catalyst exhibits excellent electrocatalytic performance for ORR (Eonset = 1.183 V,E1/2 = 0.819 V) and a low operating voltage of 1.718 V at 10 mA cm~(-2) (Ej=10) for OER.Delightfully,the home-made rechargeable Zn-air battery with CoNi/N-CNN delivers a high discharge power density up to 209 mW cm~(-2),and an outstanding charge-discharge cycling stability.The boosted bifunctional electrocatalytic activity can be ascribed to the strong coupling effect between Co/Ni center sites and defectrich N-anchored carbon featured with porous and nanotube structure,which can introduce uniformly dispersed active sites,tailored electronic configuration,superb conductivity and convenient charge transfer process.The hybrid non-precious bimetal based electrocatalyst provides the possibility to develop the low-cost and high-efficient ORR/OER bifunctional electrocatalysts in rechargeable metal-air battery.
Dendrite-free lithium anode achieved under lean-electrolyte condition through the modification of separators with F-functionalized Ti_3C_2 nanosheets

An unstable solid electrolyte interphase (SEI) and chaotic lithium ion flux are key impediments to commercial high-energy-density lithium batteries because of the uncontrolled growth of rigid lithium dendrites,which would pierce through the conventional polypropylene (PP) separator,causing short circuit and safety issues.Herein,the homogenization of lithium ion flux and the generation of stable SEI layers on lithium anodes were achieved via coating a fluorine-functionalized Ti_3C_2 (F-Ti_3C_2) nanosheets on PP separator (F-Ti_3C_2@PP).F-Ti_3C_2 nanosheets provide abundant ions pathways to homogeneously manipulate lithium ion flux and increase the Young's modulus and electrolyte wettability of the separators.In addition,F species derived from the F-Ti_3C_2 nanosheets would promote the formation of LiF-rich SEI film.The synergistic effect contribute to the uniform lithium deposition.Symmetric Li|Li,asymmetric Li|Cu and full Li|LiFePO_4 cells incorporated with the modified separators exhibit improved electrochemical performance even under lean electrolyte conditions.This work provides a feasible strategy to improve the performance of lithium batteries through both fluoridized SEI formation and lithium ion flux manipulation.
Synergy of mesoporous SnO_2 and RbF modification for high-efficiency and stable perovskite solar cells

Electron transport layer (ETL) is very critical to the performance of perovskite solar cells (PSCs),and optimization work on ETL has received extensive attentions especially on tin oxide (SnO_2) since it is an excellent ETL material widely applied in high-efficiency PSCs.Thereinto,introducing mesoporous structure and surface modification are two important approaches which are commonly applied.Herein,based on the previous work in low-temperature fabrication process of mesoporous SnO_2 (m- SnO_2),we introduced a modification process with rubidium fluoride (RbF) to the m-SnO_2 ETL,and successfully achieved a synergy of the m-SnO_2 and RbF modification:not only the shortcoming of the m- SnO_2 in interfacial traps was overcome,but also the carrier collection efficiency was further improved.The PSCs based on the m-SnO_2 ETL with RbF modification demonstrated outstanding performances:a champion power conversion efficiency (PCE) of 22.72% and a stability performance of maintaining 90% of the initial PCE after 300 h of MPP tracking were obtained without surface passivation of perovskite film.Hence,utilizing the abovementioned synergy is a cost-effective and feasible strategy for fabricating high-efficiency and stable PSCs since the fabrication process of the m-SnO_2 ETL is a kind of low temperature process and RbF is cheap.
One-pot synthesis of FeNxC as efficient catalyst for high-performance zinc-air battery

Rechargeable zinc-air batteries (ZAB) with a high theoretical energy density of 1086 Wh kg~(-1),have received tremendous research attention.However,the practical application of ZABs is still limited by high polarization and poor energy efficiency (low power density) due to the sluggish 4 electrons (e~-)/oxygen (O_2) kinetics over the air electrode.Here,a noble-metal-free FeNxC electrocatalyst is developed via a onepot approach,which provides a high density of the oxygen reduction reaction (ORR) active site and facilitates the ORR kinetics.Accordingly,the as-assembled Zn-air battery displayed a low charge-discharge voltage gap of 0.71 V at 10 mA cm~(-2),a remarkable peak power density as high as 181.2mWcm~(-2),as well as the long-term durability for hundreds of hours,among the top level of those reported previously.Our work provides a major boost for the practical application of Zn-air battery in the future.
Chemical signature and fractionation of trace elements in fine particles from anthropogenic and natural sources

The health effects of trace metal elements in atmospheric fine particulate matter (PM_(2.5) ) are widely recognized, however, the emission factor profiles and chemical fractionation of metal elements in different sources were poorly understand. In this study, sixteen metal elements, including Cd, Pb, V, Zn, Ba, Sb, As, Fe, Sr, Cr, Rb, Co, Mn, Cu, Ni and Sn from biomass burning, bituminite and anthracite combustion, as well as dust, were quantified. The results show different emission sources were associated with distinct emission profiles, holding important implications for source apportionment of ambient particulate metals. Specifically, Fe was the dominant metal species (28-1922 mg/kg) for all samples, and was followed by different metals for different samples. For dust, Mn (39.9 mg/kg_(dust) ) had the second-highest emission factor, while for biomass burning, it was Cr and Ba (7.5 and 7.4 mg/kg biomass, respectively). For bituminous coal combustion, the emission factor of Zn and Ba was 6.2 and 6.0 mg/kg_(bituminous), respectively, while for anthracite combustion the corresponding emission factor was 5.6 and 4.3 mg/kg_(anthracite), respectively. Moreover, chemical fractionation (i.e., the exchangeable, reducible fraction, oxidizable, and residual fraction) and the bioavailability index (BI) values of the metal elements from different sources were further investigated to reveal the link between different emission sources and the potential health risk. The findings from this study hold important implications for source apportionment and sourcespecific particulate metal-associated health effects.
Protonated acetone ion chemical ionization time-of-flight mass spectrometry for real-time measurement of atmospheric ammonia

Ammonia (NH_3 ) is ubiquitous in the atmosphere, it can affect the formation of secondary aerosols and particulate matter, and cause soil eutrophication through sedimentation. Currently, the use of radioactive primary reagent ion source and the humidity interference on the sensitivity and stability are the two major issues faced by chemical ionization mass spectrometer (CIMS) in the analysis of atmospheric ammonia. In this work, a vacuum ultraviolet (VUV) Kr lamp was used to replace the radioactive source, and acetone was ionized under atmospheric pressure to obtain protonated acetone reagent ions to ionize ammonia. The ionization source is designed as a separated three-zone structure, and even 90 vol.% high-humidity samples can still be directly analyzed with a sensitivity of sub-ppbv. A signal normalization processing method was designed, and with this new method, the quantitative relative standard deviation (RSD) of the instrument was decreased from 17.5% to 9.1%, and the coefficient of determination was increased from 0.8340 to 0.9856. The humidity correction parameters of the instrument were calculated from different humidity, and the ammonia concentrations obtained under different humidity were converted to its concentration under zero humidity condition with these correction parameters. The analytical time for a single sample is only 60 sec, and the limit of detection (LOD) was 8.59 pptv (signaltonoise ratio S/N = 3). The ambient measurement made in Qingdao, China, in January 2021 with this newly designed CIMS, showed that the concentration of ammonia ranged from 1 to 130 ppbv.
Constant-round auction with insulated bidders

In recent years, online auction has gained widespread popularity as a primary characteristic of electronic commerce among masses. It has also become a primary topic of research interest. Cryptographic primitives such as secure multiparty computation (MPC), zero-knowledge proof (ZKP) and commitment scheme are being effectively utilized for the proposal of various schemes. Therefore, these schemes have become much more inefficient and complicated, thereby rendering them suitable only for auction with a small number of bidders. Efficiency needs to be considered as an important factor for a real auction, especially if it is conducted online.
Constructibility of a causal/impulse free NDS using descriptor form subsystems

Requirements are investigated in this paper for each descriptor form subsystem, with which a causal/impulse free networked dynamic system (NDS) can be constructed. For this purpose, a matrix rank-based necessary and sufficient condition is at first derived for the causality/impulse freeness of an NDS, with the matrix depending affinely on subsystem connections. From this result, a necessary and sufficient condition is derived on each subsystem for causal/impulse free NDS constructibility. This condition further leads to a necessary and sufficient condition for the existence of a local static output feedback that guarantees the construction of a causal/impulse free NDS. Remarkably, all the numerical computations involved in these conditions are performed independently on each individual subsystem. Situations have also been clarified in which NDS causality/impulse freeness is independent of subsystem connections. It has also been made clear that local static output feedbacks may not be helpful in constructing a causal NDS.

Morphology control in high-efficiency all-polymer solar cells

All-polymer solar cells (All-PSCs) have attracted tremendous research interest in the recent decade due to the great potentials in stretchable electronic applications in terms of long-term stability and mechanical stretchability. Driven by the molecular design of novel polymer acceptors and morphology optimization, the power conversion efficiency (PCE) of All-PSCs has developed rapidly and now exceeded 17%. This review outlines the promising strategies for high-performance All-PSCs from the aspect of morphology control with the motivation to rationally guide the optimization. In this review, we briefly discuss the thermodynamic mixing principles of all-polymer blends and the effects of the molecular structure of conjugated polymers on thin-film morphology in All-PSCs. The crucial role of molecular miscibility in influencing morphological features and performance metrics was highlighted. We also expound on the effective methods of controlling film morphology through properly tuning the aggregation behavior of polymers. In particular, insightful studies on the commonly used naphthalene diimide-based acceptor polymers and the newly emerging polymerized nonfullerene small molecule acceptors (ITIC-series, Y6 -series, etc) are discussed in detail. Finally, we present an outlook on the major challenges and the new opportunities of All-PSCs for efficiency breakthroughs targeting 20%.

Oreocharis xieyongii, an unusual new species of Gesneriaceae from western Hunan, China

A new species, Oreocharis xieyongii T. Deng, D.G. Zhang & H. Sun, from Hunan Province, central China, is described. The combination of purple zygomorphic corolla with longer adaxial lobes and exserted stamens defines the species and discriminates it from all other current Oreocharis species. Morphological traits of the new species were compared to those of two similar species, Oreocharis xiangguiensis and O. rubrostriata. Phylogenetic analysis indicates that the new species is nested within the Oreocharis. Although only half of Oreocharis species were included in our study, evolutionary character analysis indicates that the ancestral states of the genus are likely the purple corolla, longer abaxial lip and inserted stamens. The longer adaxial lip is perhaps an apomorphy and only present in O. xieyongii and O. rubrostriata. Both morphological and molecular evidence suggest that O. xieyongii is a taxon new to science.
Identification and fine mapping of rtms1-D, a gene responsible for reverse thermosensitive genic male sterility from Diannong S-1X

Thermosensitive genic male sterility (TGMS) has been widely used in two-line hybrid rice breeding. Due to hybrid seed production being highly affected by changeable environments, its application scope is limited to some extent. Thus, it is of great importance to identify potential TGMS genes in specific rice varieties. Here, Diannong S-l xuan (DNS-1X), a reverse TGMS (RTGMS) japonica male sterile line, was identified from Diannong S-l. Genetic analysis showed that male sterility was tightly controlled by a single recessive gene, which was supported by the phenotype of the F1 and F2:3 populations derived from the cross between DNS-1X and Yunjing 26 (YJ26). Combining simple sequence repeat (SSR) markers and bulked segregation analysis (BSA), we identified a 215 kb region on chromosome 10 as a candidate reverse TGMS region, which was designated as rtms 1-D. It was narrower than the previously reported RTGMS genes rtms1 and tms6(t). The fertility conversion detected in the natural environment showed that DNS-1X was sterile below 28-30 °C; otherwise, it was fertile. Histological analysis further indicated that the pollen abortion was occurred in the young microspore stage. This study will provide new resources for two-line hybrid rice and pave the way for molecular breeding of RTGMS lines.
Genome size evolution of the extant lycophytes and ferns

Ferns and lycophytes have remarkably large genomes. However, little is known about how their genome size evolved in fern lineages. To explore the origins and evolution of chromosome numbers and genome size in ferns, we used flow cytometry to measure the genomes of 240 species (255 samples) of extant ferns and lycophytes comprising 27 families and 72 genera, of which 228 species (242 samples) represent new reports. We analyzed correlations among genome size, spore size, chromosomal features, phylogeny, and habitat type preference within a phylogenetic framework. We also applied ANOVA and multinomial logistic regression analysis to preference of habitat type and genome size. Using the phylogeny, we conducted ancestral character reconstruction for habitat types and tested whether genome size changes simultaneously with shifts in habitat preference. We found that 2C values had weak phylogenetic signal, whereas the base number of chromosomes (x) had a strong phylogenetic signal. Furthermore, our analyses revealed a positive correlation between genome size and chromosome traits, indicating that the base number of chromosomes (x), chromosome size, and polyploidization may be primary contributors to genome expansion in ferns and lycophytes. Genome sizes in different habitat types varied significantly and were significantly correlated with habitat types; specifically, multinomial logistic regression indicated that species with larger 2C values were more likely to be epiphytes. Terrestrial habitat is inferred to be ancestral for both extant ferns and lycophytes, whereas transitions to other habitat types occurred as the major clades emerged. Shifts in habitat types appear be followed by periods of genomic stability. Based on these results, we inferred that habitat type changes and multiple whole-genome duplications have contributed to the formation of large genomes of ferns and their allies during their evolutionary history.
