Reduced graphene oxide-based calcium alginate hydrogel as highly efficient solar steam generation membrane for desalination

Solar-driven evaporation has been considered as one of the potential methods for desalination and sewage treatment. However, optical concentrators and complex multi-component systems are essential in advanced technologies, resulting in low efficiency and high cost. Here, we synthesize a reduced graphene oxide-based porous calcium alginate (CA-rGO) hydrogel which exhibits good performance in light absorption. More than 90% of the light in the whole spectrum can be absorbed. Meanwhile, the water vapor escapes from the CA-rGO film extremely fast. The water evaporation rate is 1.47 kg·m~(-2)·h~(-1), corresponding to the efficiency 77% under only 1 kW·m~(-2) irradiation. The high evaporation efficiency is attributed to the distinctive structure of the film, which contains inherent porous structure of hydrogel enabling rapid water transport throughout the film,and the concave water surfaces formed in the hydrophilic pores provide a large surface area for evaporation. Hydrophobic rGO divides the evaporation surface and provides a longer three-phase evaporation line. The test on multiple cyclic radiation shows that the material has good stability. The CA-rGO hydrogel may have promising application as a membrane for solar steam generation in desalination and sewage treatment.
Signal Acquisition and Processing Method for Capacitive Electromagnetic Flowmeter

A kind of signal acquisition circuit and the related signal processing method of the capacitance electromagnetic flowmeter (EMF) were introduced.The circuit can eliminate the influence of distributed capacitance on the input impedance of the operational amplifier,and greatly improve the input impedance of the detection circuit to overcome the disadvantage of high signal source impedance.The rotating capacitor filter is a signal processing method based on the phase-sensitive detection technology.It can extract the weak signal from the strong and wideband background noise,so it is very suitable for the processing of capacitive electromagnetic flow signals.Through the comparison of the signal amplitude obtained at different flow rates and the comparison of signal spectrum components before and after the filter,the effectiveness of the bootstrap signal acquisition circuit and rotating capacitor filtering method is verified.

重视环境污染对肾脏的损害

环境污染是影响公众健康和死亡的重要原因之一,肾脏的血液供应占心输出量的20%,血液经过肾小球滤过后,在肾小管上皮细胞重吸收,环境毒素可以浓集,因而肾脏容易受到环境污染的损害。环境污染是造成慢性肾脏病(CKD)疾病谱变迁和不同地区疾病谱不同的重要的因素之一。近年,针对环境污染对肾脏损害的因素进行了大量的临床与基础研究,由于环境污染因素众多,对肾脏损害的机制和临床表现多种多样,环境污染对肾脏的损害没有得到应有重视和深刻的认识。

Regulation of cardiomyocyte fate plasticity:a key strategy for cardiac regeneration

With the high morbidity and mortality rates,cardiovascular diseases have become one of the most concerning diseases worldwide.The heart of adult mammals can hardly regenerate naturally after injury because adult cardiomyocytes have already exited the cell cycle,which subseqently triggers cardiac remodeling and heart failure.Although a series of pharmacological treatments and surgical methods have been utilized to improve heart functions,they cannot replenish the massive loss of beating cardiomyocytes after injury.Here,we summarize the latest research progress in cardiac regeneration and heart repair through altering cardiomyocyte fate plasticity,which is emerging as an effective strategy to compensate for the loss of functional cardiomyocytes and improve the impaired heart functions.First,residual cardiomyocytes in damaged hearts re-enter the cell cycle to acquire the proliferative capacity by the modifications of cell cycle-related genes or regulation of growth-related signals.Additionally,non-cardiomyocytes such as cardiac fibroblasts,were shown to be reprogrammed into cardiomyocytes and thus favor the repair of damaged hearts.Moreover,pluripotent stem cells have been shown to transform into cardiomyocytes to promote heart healing after myocardial infarction (Ml).Furthermore,in vitro and in vivo studies demonstrated that environmental oxygen,energy metabolism,extracellular factors,nerves,non-coding RNAs,etc.play the key regulatory functions in cardiac regeneration.These findings provide the theoretical basis of targeting cellular fate plasticity to induce cardiomyocyte proliferation or formation,and also provide the clues for stimulating heart repair after injury.
The calcium-dependent protein kinase ZmCDPK7 functions in heat-stress tolerance in maize

Global warming poses a serious threat to crops. Calcium-dependent protein kinases (CDPKs)/CPKs play vital roles in plant stress responses, but their exact roles in plant thermotolerance remains elusive. Here, we explored the roles of heat-induced ZmCDPK7 in thermotolerance in maize. ZmCDPK7-overexpressing maize plants displayed higher thermotolerance, photosynthetic rates, and antioxidant enzyme activity but lower H_2O_2 and malondialdehyde (MDA) contents than wild-type plants under heat stress. ZmCDPK7-knockdown plants displayed the opposite patterns. ZmCDPK7 is attached to the plasma membrane but can translocate to the cytosol under heat stress. ZmCDPK7 interacts with the small heat shock protein sHSP17.4, phosphorylates sHSP17.4 at Ser-44 and the respiratory burst oxidase homolog RBOHB at Ser-99, and upregulates their expression. Site-directed mutagenesis of sHSP17.4 to generate a Ser-44-Ala substitution reduced ZmCDPK7's enhancement of catalase activity but enhanced ZmCDPK7's suppression of MDA accumulation in heat-stressed maize protoplasts. sHSP17.4, ZmCDPK7, and RBOHB were less strongly upregulated in response to heat stress in the abscisic acid-deficient mutant vp5 versus the wild type. Pretreatment with an RBOH inhibitor suppressed sHSP17.4 and ZmCDPK7 expression. Therefore, abscisic acid-induced ZmCDPK7 functions both upstream and downstream of RBOH and participates in thermotolerance in maize by mediating the phosphorylation of sHSP17.4, which might be essential for its chaperone function.
Global-Scale Diversity and Distribution Characteristics of Reef-Associated Symbiodiniaceae via the Cluster-Based Parsimony of Internal Transcribed Spacer 2 Sequences

Photosynthetic species belonging to Symbiodiniaceae play important ecological roles in coral reef ecosystems.Nine phylogenetically supported Symbiodiniaceae clades(each containing multiple genetically distinct molecular types)have been detected in reef-associated animals and in seawater or sediments near coral reef areas.Although major advances in research on Symbiodiniaceae diversity have been made,information on the global-scale diversity and distribution characteristics of Symbiodiniaceae clades/types is still limited or must be expanded because most studies on Symbiodiniaceae have mainly focused on a limited number of hosts associated with Symbiodiniaceae or coral reef areas.Here,the diversity and distribution characteristics of Symbiodiniaceae data derived from reef-associated animals and seawater or sediments near coral reef areas were analyzed using 3899 qualified Symbiodiniaceae internal transcribed spacer 2(ITS2)sequences retrieved from the GenBank database in May 2017.These sequences were annotated as Symbiodiniaceae ITS2 types via sequence alignment against database of Symbiodiniaceae ITS2 types.Results showed that photosynthetic Symbiodiniaceae ITS2 sequences could be annotated as 119 Symbiodiniaceae ITS2 types within nine clades(A-I),and Symbiodiniaceae ITS2 types mainly inhabited coral reefs between 30°N and 30°S.Symbiodiniaceae ITS2 types could be associated with multiple host taxa.Interestingly,these results implied that the distribution of Symbiodiniaceae ITS2 types was distinct in the Atlantic Ocean,the Red Sea,the Mediterranean Sea,and the Indo-Pacific Ocean.Although future field research should be performed to verify our results,this study provided a broad perspective of the diversity of Symbiodiniaceae clades/types on a global scale.
Electrochemical and Pseudocapacitive Analysis of Rod-Like MoO_2 @ MoSe_2 @NC Heterostructures for High-Performance Lithium Ion Batteries

A micro-scale rod-like heterostructure derived from molybdenum-based metal organic framework (Mo-MOF) has been successfully prepared via subsequent annealing treatment, which assembled from N-doped carbon encapsulated MoSe_2 nanosheets grown on the surface of MoO_2 microrod (named as MoO_2 @MoSe_2 @NC). For this novel heterostructure, the MoO_2 nanoparticles assembled into rod core not only serve as supporting substrate for facilitating the fast kinetics of Li~+ cations inside the electrode but also protect the MoSe_2 structure from restacking in the charge/discharge process. Moreover, the outer-layered MoSe_2 nanosheets enable the fast lithium ion movement owing to its large interlayer spacing. Moreover, this unique rod-like core-shell structure composite could further effectively alleviate the structural strains caused by large volume expansion during charge/discharge process, thus leading to stable electrochemical performance when evaluated as anode material for lithium ion batteries. Electrochemical testing exhibits that the MoO_2 @MoSe_2 @NC heterostructure presents highly reversible capacity of 468 mAh g ~(-1) at 0.5 A g ~(-1) and superior rate capability (318 mAh g ~(-1) even at 5.0 A g ~(-1)), which is attributed to the synergistic effect of N-doped carbon encapsulated MoSe_2 nanosheets and MoO_2 nanoparticles.
Effect of LiTFSI and LiFSI on Cycling Performance of Lithium Metal Batteries Using Thermoplastic Polyurethane/Halloysite Nanotubes Solid Electrolyte

All-solid-state lithium batteries (ASSLB) are promising candidates for next-generation energy storage devices. Nevertheless, the large-scale commercial application of high energy density ASSLB with the polymer electrolyte still faces challenges. In this study, a thin solid polymer composite electrolyte (SPCE) is prepared through a facile and cost-effective strategy with an infiltration of thermoplastic polyurethane (TPU), lithium salt (LiTFSI or LiFSI), and halloysite nanotubes (HNTs) in a porous framework of polyethylene separator (PE) (TPU-HNTs-LiTFSI-PE or TPU-HNTs-LiFSI-PE). The composition, electrochemical performance, and especially the effect of anions (TFSI - and FSI -) on cycling performance are investigated. The results reveal that the flexible TPU-HNTs-LiTFSI-PE and TPU-HNTs-LiFSI-PE with a thickness of 34 μm exhibit wide electrochemical windows of 4.9 and 5.1 V (vs. Li + /Li) at 60 ℃, respectively. Reduction in FSI - tends to form more LiF and sulfur compounds at the interface between TPU-HNTs-LiFSI-PE and Li metal anode, thus enhancing the interfacial stability. As a result, cell composed of TPU-HNTs-LiFSI-PE exhibits a smaller increase in interfacial resistance of solid electrolyte interphase (SEI) with a distinct decrease in charge-transfer resistance during cycling. Li|Li symmetric cell with TPU-HNTs-LiFSI-PE could keep its stable overpotential profile for nearly 1300 h with a low hysteresis of approximately 39 mV at a current density of 0.1 mA cm ~(-2), while a sudden voltage rise with internal cell impedance-surge signals was observed within 600 h for cell composed of TPU-HNTs-LiTFSI-PE. The initial capacities of NCM|TPU-HNTs-LiTFSI- PE|Li and NCM|TPU-HNTs-LiFSI-PE|Li cells were 149 and 114 mAh g ~(-1), with capacity retention rates of 83.52% and 89.99% after 300 cycles at 0.5 C, respectively. This study provides a valuable guideline for designing flexible SPCE, which shows great application prospect in the practice of ASSLB.
A Review of Al Alloy Anodes for Al-Air Batteries in Neutral and Alkaline Aqueous Electrolytes

Aluminum-air (Al-air) batteries are promising candidates for energy storage applications because of their high theoretical energy density and low cost. Nevertheless, their developments have been severely hindered by multiple obstacles, among which the activation and self-corrosion inhibition of Al anode have been considered to be significant challenges. In neutral electrolytes, the main problem is the activation of Al anode, while the self-corrosion of Al anode becomes dominant in alkaline electrolytes. Considerable efforts have been devoted to overcoming the dilemma associated with the Al anode. This review firstly underscores the underlying mechanisms of passivation and self-corrosion of Al anode in different electrolytes. Then, specific attentions are paid to Al alloy anode, including the role of various elements and standard processing technology. Finally, general conclusions, current limitations, and future perspectives on Al alloy anode are presented.
Cryo-EM structure of the human mitochondrial translocase TIM22 complex

Mitochondria are essential organelles in cellular metabolism, homeostasis, and apoptosis. Most mitochondrial proteins are synthesized as precursors in the cytosol and then imported into mitochondria by specific protein translocase complexes, including the translocase of the outer membrane complex(TOM complex), the carrier translocase of the inner membrane complex(TIM22 complex), the presequence translocase of the inner membrane complex(TIM23 complex), the sorting and assembly machinery(SAM complex), and the mitochondrial import complex(MIM complex).3 The TIM22 complex is responsible for the translocation and insertion of hydrophobic membrane proteins, including mitochondrial carrier proteins and translocase subunits(Tim17, Tim22 and Tim23). In humans, TIM22 is a 440-kDa complex comprising at least six components: the hypothetical channelforming protein Tim22, three small Tim proteins(Tim9, Tim10a and Tim10b), Tim29 and acylglycerol kinase(AGK). Considering the functional importance of mitochondrial protein import, the TIM22 complex has been linked to many diseases. For example, mutations in the TIM22 gene have been reported to cause earlyonset mitochondrial myopathy. AGK participates in lipid biosynthesis, and mutations in the AGK gene lead to Sengers syndrome. Mutations in the TIMM8A gene(also called DDP1)cause deafness dystonia syndrome.
Reduced-right posterior sector salvage liver transplantation using a moderate steatotic graft from one obese donor after cardiac death

Compared with the majority of reduced-size liver transplantations (RSLTs) performed in pediatric recipients, the experience of RSLTs in adult recipients and surgical strategies for the reduction of grafts are relatively unfamiliar. Herein,we report a successful case of adult-to-adult RSLT,in which a unique method for removing the right posterior sector while preserving the right hepatic vein (RHV) was performed. This study was approved by the West China Hospital Ethics Committee (No. 2019-718) and was conducted in accordance with the ethical guidelines of the Declaration of Helsinki.
Metachronal propulsion of non-Newtonian viscoelastic mucus in an axisymmetric tube with ciliated walls

Cilia-induced flow of viscoelastic mucus through an idealized two-dimensional model of the human trachea is presented. The cilia motion is simulated by a metachronal wave pattern which enables the mobilization of highly viscous mucus even at nonzero Reynolds numbers. The viscoelastic mucus is analyzed with the upper convected Maxwell viscoelastic formulation which features a relaxation time and accurately captures normal stress generation in shear flows. The governing equations are transformed from fixed to wave (laboratory) frame with appropriate variables and resulting differential equations are perturbed about wave number. The trachea is treated as an axisymmetric ciliated tube. Radial and axial distributions in axial velocity are calculated via the regular perturbation method and pressure rise is computed with numerical integration using symbolic software MATHEMATICA ™. The influence of selected parameters which is cilia length, and Maxwell viscoelastic material parameter i.e. relaxation time for prescribed values of wave number are visualized graphically. Pressure rise is observed to increase considerably with elevation in both cilia length and relaxation time whereas the axial velocity is markedly decelerated. The simulations provide some insight into viscous-dominated cilia propulsion of rheological mucus and also serve as a benchmark for more advanced modeling.
Concentration, sources and wet deposition of dissolved nitrogen and organic carbon in the Northern Indo-Gangetic Plain during monsoon

Precipitation represents an important phenomenon for carbon and nitrogen deposition. Here, the concentrations and fluxes of dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) with their potential sources were analyzed in wet precipitation during summer monsoon from the Northern Indo-Gangetic Plain (IGP), important but neglected area. The volume-weighted mean (VWM) concentration of DOC and TDN were 687.04 and 1210.23 μg/L, respectively. Similarly, the VWM concentration of major ions were in a sequence of NH_4~+ > Ca~(2 +) > SO_4~(2-) > Na~+ > K~+ > NO_3~ - > Cl~- > Mg~(2 +) > F~- > NO_2~ -, suggesting NH_4~+ and Ca~(2 +) from agricultural activities and crustal dust played a vital role in precipitation chemistry. Moreover, the wet deposition flux of DOC and TDN were 9.95 and 17.06 kg/(ha· year), respectively. The wet deposition flux of inorganic nitrogen species such as NH_4~+ -N and NO_3~ --N were 14.31 and 0.47 kg/(ha ∑year), respectively, demonstrating the strong influence of emission sources and precipitation volume. Source attribution from different analysis suggested the influence of biomass burning on DOC and anthropogenic activities (agriculture, animal husbandry) on nitrogenous species. The air-mass back trajectory analysis indicated the influence of air masses originating from the Bay of Bengal, which possibly carried marine and anthropogenic pollutants along with the biomass burning emissions to the sampling site. This study bridges the data gap in the less studied part of the northern IGP region and provides new information for policy makers to deal with pollution control.
Significant influences of TiO_2 crystal structures on NO_2 and HONO emissions from the nitrates photolysis

The emissions of NO_2 and HONO from the KNO_3 photolysis in the presence of TiO_2 were measured using a round-shape reactor coupled to a NO_x analyzer. TiO_2 played important roles in the emission flux density of NO_2 (R NO_2) and HONO (R HONO), depending on crystal structures and mass ratios of TiO_2. R NO_2 and R HONO significantly decreased with increasing the rutile and anatase mass ratios from 0 to 8 and 0.5 wt.%, respectively. Nevertheless, with further increasing the anatase mass ratio to 8 wt.%, there was an increase in R NO_2 and R HONO. R NO_2 on KNO_3 /TiO_2 /SiO 2 had positive correlation with the KNO_3 mass (1-20 wt.%), irradiation intensity (80-400 W/m 2) and temperature (278-308 K), while it had the maximum value at the relative humidity (RH) of 55%. R HONO on KNO_3 /TiO_2 /SiO 2 slightly varied with the KNO_3 mass and temperature, whereas it increased with the irradiation intensity and RH. In addition, the mechanism for NO_2 and HONO emissions from the nitrates photolysis and atmospheric implications were discussed.
Nitrated and parent PAHs in the surface water of Lake Taihu, China: Occurrence, distribution, source, and human health risk assessment

Nitrated polycyclic aromatic hydrocarbons (NPAHs) have toxic potentials that are higher than those of their corresponding parent polycyclic aromatic hydrocarbons (PAHs) and thus have received increasing attention in recent years. In this study, the occurrence, distribution, source, and human health risk assessment of 15 NPAHs and 16 PAHs were investigated in the surface water from 20 sampling sites of Lake Taihu during the dry, normal, and flood seasons of 2018. The ∑PAH concentrations ranged from 255 to 7298 ng/L and the ∑NPAH concentrations ranged from not-detected (ND) to 212 ng/L. Among the target analytes, 2- nitrofluorene (2-nFlu) was the predominant NPAH, with a detection frequency ranging from 85% to 90% and a maximum concentration of 56.2 ng/L. The three-ringed and four-ringed NPAHs and PAHs comprised the majority of the detected compounds. In terms of seasonal variation, the highest levels of the ∑NPAHs and ∑PAHs were in the dry season and flood season, respectively. Diagnostic ratio analysis indicated that the prime source of NPAHs was direct combustion, whereas in the case of PAHs the contribution was predominantly from a mixed pattern including pollution from unburned petroleum and petroleum combustion. The human health risk of NPAHs and PAHs was evaluated using a lifetime carcinogenic risk assessment model. The carcinogenic risk level of the targets ranged from 2.09 × 10~(-7) to 5.75 × 10~(-5) and some surface water samples posed a potential health risk.
Simultaneous measurement of aqueous redox-sensitive elements and their species across the soil-water interface

The redox-sensitive elements, such as iron, manganese, sulfur, phosphorus, and arsenic, shift their speciation every millimeter (mm) across the soil-water interface in the flooded soil environments. Monitoring of element speciation at this high-resolution (HR) within the SWI is still difficult. The key challenge lies in obtaining sufficient porewater samples at specific locations along the soil gradient for downstream analysis. Here with an optimized inductively coupled plasma mass spectrometry (ICP-MS) method and a HR porewater sampler, we demonstrate mm-scale element profiles mapping across the SWI in paddy soils. Highconcentrations of iron and manganese (> 10 mg/L) were measured by ICP-MS in an extended dynamic range mode to avoid signal overflow. The iron profile along the SWI generated by the ICP-MS method showed no significant difference (p < 0.05) compared to that measured independently using a colorimetric method. Furthermore, four arsenic (arsenite, arsenate, monomethylarsonic and dimethylarsinic acid), two phosphorus (phosphite and phosphate) and two sulfur (sulfide and sulfate) species were separated in 10 min by ion chromatography -ICP-MS with the NH 4 HCO 3 mobile phase. We verified the technique using paddy soils collected from the field, and present the mm-scale profiles of iron, manganese, and arsenic, phosphorus, sulfur species (relative standard deviation < 8%). The technique developed in this study will significantly promote the measurement throughput in limited samples (e.g. 100 μL) collected by HR samplers, which would greatly facilitate redox-sensitive elements biogeochemical cycling in saturated soils.
