Research progress of defect-engineered UiO-66(Zr) MOFs for photocatalytic hydrogen production

In recent years, defect-engineered Zr-based UiO-66 metal-organic frameworks (UiO-66(Zr) metalorganic frameworks (MOFs)) have shown huge advantages in catalytic, functional materials, adsorption,and other fields due to their large surface areas, well-ordered porous structures, and flexible tailorability. It is extremely challenging to introduce defect sites in the synthesis of MOFs to regulate the physicochemical properties of materials such as (energy band structure, pore structure, etc.) to obtain an excellent performance. This paper reviews the recent research results of synthesis methods, characterization technologies, and application fields of defect-engineered UiO-66(Zr) MOFs materials in order to provide new insights to synthesize high-performance UiO-66(Zr) MOFs materials and promote the development of UiO-66(Zr) in various fields.
Organic conjugated polymers and polymer dots as photocatalysts for hydrogen production

Owing to the outstanding characteristics of tailorable electronic and optical properties, semiconducting polymers have attracted considerable attention in recent years. Among them, organic polymer dots process large breadth of potential synthetic diversity are the representative of photocatalysts for hydrogen production, which presents both an opportunity and a challenge. In this mini-review, first, the organic polymer photocatalysts were introduced. Then, recent reports on polymer dots which showed a superior photocatalytic activity and a robust stability under visible-light irradiation, for hydrogen production were summarized. Finally, challenges and outlook on using organic polymer dots-based photocatalysts from hydrogen production were discussed.
Visible light responsive photocatalysts developed by substitution with metal cations aiming at artificial photosynthesis

To solve resource, energy, and environmental issues, development of sustainable clean energy system is strongly required. In recent years, hydrogen has been paid much attention to as a clean energy. Solar hydrogen production by water splitting using a photocatalyst as artificial photosynthesis is a promising method to solve these issues. Efficient utilization of visible light comprised of solar light is essential for practical use. Three strategies, i.e., doping, control of valence band, and formation of solid solution are often utilized as the useful methods to develop visible light responsive photocatalysts. This minireview introduces the recent work on visible-light-driven photocatalysts developed by substitution with metal cations of those strategies.
Effects of taping on grinding quality of silicon wafers in backgrinding

Taping is often used to protect patterned wafers and reduce fragmentation during backgrinding of silicon wafers. Grinding experiments using coarse and fine resinbond diamond grinding wheels were performed on silicon wafers with tapes of different thicknesses to investigate the effects of taping on peak-to-valley (PV), surface roughness, and subsurface damage of silicon wafers after grinding. Results showed that taping in backgrinding could provide effective protection for ground wafers from breakage. However, the PV value, surface roughness, and subsurface damage of silicon wafers with taping deteriorated compared with those without taping although the deterioration extents were very limited. The PV value of silicon wafers with taping decreased with increasing mesh size of the grinding wheel and the final thickness. The surface roughness and subsurface damage of silicon wafers with taping decreased with increasing mesh size of grinding wheel but was not affected by removal thickness. We hope the experimental finding could help fully understand the role of taping in backgrinding.
Rotation-translation coupling of a double-headed Brownian motor in a traveling-wave potential

Considering a double-headed Brownian motor moving with both translational and rotational degrees of freedom,we investigate the directed transport properties of the system in a traveling-wave potential.It is found that the traveling wave provides the essential condition of the directed transport for the system,and at an appropriate angular frequency,the positive current can be optimized.A general current reversal appears by modulating the angular frequency of the traveling wave,noise intensity,external driving force and the rod length.By transforming the dynamical equation in traveling-wave potential into that in a tilted potential,the mechanism of current reversal is analyzed.For both cases of Gaussian and Levy noises,the currents show similar dependence on the parameters.Moreover,the current in the tilted potential shows a typical stochastic resonance effect.The external driving force has also a resonance-like effect on the current in the tilted potential.But the current in the traveling-wave potential exhibits the reverse behaviors of that in the tilted potential.Besides,the currents obviously depend on the stability index of the Levy noise under certain conditions.
Lower risk of subarachnoid haemorrhage in diabetes: a nationwide population-based cohort study

Background and purpose Diabetes mellitus (DM) is a common metabolic disorder with increased risk of cardiovascular and cerebrovascular complications. However, its relationship with risk of subarachnoid haemorrhage (SAH),the most devastating form of stroke, remains controversial. Methods To evaluate the relationship between DM and risk of SAH,we performed a retrospective cohort study using a nationwide, population-based, health screening database in Korea. We included participants without history of stroke who underwent a nationwide health screening programme between 2003 and 2004. Primary outcome was occurrence of SAH. Participants were followed up until development of SAH or December 2015. Multivariate Cox proportional hazards regression analysis was performed with adjustments for age, sex, systolic blood pressure, total cholesterol, body mass index, physical activity, smoking status, alcohol habit, household income and treatment with antihypertensive agents and statins. Results Among 421 768 study participants, prevalence of DM was 9.6%. During a mean follow-up period of 11.6±1.9 years, 1039 patients developed SAH. Presence of DM was significantly associated with decreased risk of SAH (adjusted HR 0.68;95% CI 0.53 to 0.86;p<0.001). Elevated level of fasting blood glucose was also negatively associated with risk of SAH (adjusted HR per 1 mmol/L increase 0.90;95% CI 0.86 to 0.95;p<0.001). Conclusion DM and elevated level of fasting blood glucose were inversely associated with risk of SAH. Further studies may elucidate the possibly protective, pathophysiological role played by hyperglycaemia in patients at risk of SAH.

Recent progress of efficient flexible solar cells based on nanostructures

Flexible solar cells are important photovoltaics (PV) technologies due to the reduced processing temperature,less material consumption and mechanical flexibility,thus they have promising applications for portable devices and building-integrated applications.However,the efficient harvesting of photons is the core hindrance towards efficient,flexible PV.Light management by nanostructures and nanomaterials has opened new pathways for sufficient solar energy harvesting.Nanostructures on top surfaces provide an efficient pathway for the propagation of light.Aside from suppressing incident light reflection,micro-structured back-reflectors reduce transmission via multiple reflections.Nanostructures themselves can be the absorber layer.Photovoltaics based on high-crystallinity nanostructured light absorbers demonstrate enhanced power conversion efficiency (PCE) and excellent mechanical flexibility.To acquire a deep understanding of the impacts of nanostructures,herein,a concise overview of the recent development in the design and application of nanostructures and nanomaterials for photovoltaics is summarized.
CDE4 encodes a pentatricopeptide repeat protein involved in chloroplast RNA splicing and affects chloroplast development under low‐temperature conditions in riceOO

Pentatricopeptide repeat (PPR) proteins play important roles in the post‐transcriptional modification of organellar RNAs in plants. However, the function of most PPR proteins remains unknown. Here, we characterized the rice (Oryza sativa L.) chlorophyll deficient 4 (cde4) mutant which exhibits an albino phenotype during early leaf development, with decreased chlorophyll contents and abnormal chloroplasts at low‐temperature (20°C). Positional cloning revealed that CDE4 encodes a P‐type PPR protein localized in chloroplasts. In the cde4 mutant, plastid‐encoded polymerase (PEP)‐dependent transcript levels were significantly reduced, but transcript levels of nuclear‐encoded genes were increased compared to wild‐type plants at 20°C. CDE4 directly binds to the transcripts of the chloroplast genes rpl2, ndhA, and ndhB. Intron splicing of these transcripts was defective in the cde4 mutant at 20°C, but was normal at 32°C. Moreover, CDE4 interacts with the guanylate kinase VIRESCENT 2 (V2); overexpression of V2 enhanced CDE4 protein stability, thereby rescuing the cde4 phenotype at 20°C. Our results suggest that CDE4 participates in plastid RNA splicing and plays an important role in rice chloroplast development under lowtemperature conditions.
Sinusoidal Vertical Motion Suppression and Flow Noise Calculation for a Sonobuoy

The flow noise associated with sinusoidal vertical motion of a sonobuoy restrains its working performance. In practice, a suspension system consisting of elastic suspension cable and isolation mass is adopted to isolate the hydrophone from large vertical motions of the buoy on the ocean surface. In the present study, a theoretical model of vertical motion based on the sonobuoy suspension system was proposed. The vertical motion velocity response of the hydrophone of a sonobuoy can be obtained by solving the theoretical model with Runge-Kutta algorithm. The flow noise of the hydrophone at this response motion velocity was predicted using a hybrid computational fluid dynamics (CFD)-Ffowcs Williams-Hawkings (FW-H) technique. The simulation results revealed that adding the elastic suspension cable with an appropriate elastic constant and counterweight with an appropriate mass have a good effect on reducing the flow noise caused by the sonobuoy vertical motion. The validation of this hybrid computational method used for reliable prediction of flow noise was also carried out on the basis of experimental data and empirical formula. The finds of this study can supply the deep understandings of the relationships between flow noise reduction and sonobuoy optimization.
Clinical phenotypes of patients with obstructive sleep apnea-hypopnea syndrome: a cluster analysis

To the Editor: Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a common sleep-disordered breathing disease with a range of harmful sequelae. As a syndrome related to multiple systems, the clinical presentation of OSAHS is characterized by a large heterogeneity. At the World Sleep 2019 conference, a series of cluster analyses on the Icelandic sleep apnea cohort were introduced in detail. However, data from China are missing due to less relevant studies. Furthermore, although the relationship between OSAHS and cognitive impairment was confirmed in the 1980s,all variables assessing cognitive function have not yet been explored.
Glutamic acid-assisted hydrothermal recrystallization to configure bamboo-like carbon nanotubes for improved triiodide reduction

Carbon nanotubes (CNTs) have been far and wide employed as the counter electrodes (CEs) in dyesensitized solar cells because of their individual physical and chemical properties. However, the techniques available now, such as chemical vapor deposition, arc discharge and laser ablation for synthesizing CNTs, commonly suffer from rigorous operations and complicated steps, which make the process difficult to be controlled. Herein, we present a simple and facile glutamic acid-assisted hydrothermal recrystallization strategy to construct bamboo-like CNTs (GHP-BC-x). Generally, the conventional organic dye 3,4,9,10-perylene tetracarboxylic dianhydride (PTCDA) is used as a precursor and glutamic acid efficiently promotes the recrystallization of the perylene cores' planar p-conjugated system in PTCDA under hydrothermal conditions and then self-assembles into one-dimensional nanorods with improved crystallization degree, finally resulting in the morphology of bamboo-like CNTs after carbonization. When applied as the counter electrodes, the GHP-BC-3 displays a remarkable power conversion efficiency of 8.25%, benefiting from the superb electrical conductivity and mass transfer dynamics, superior to that of Pt CE (7.62%).
Characterization of wet microalgal cells pretreated with steam for lipid extraction

Steam pretreatment was employed to disrupt microalgal cells for lipids extraction. Effects of steam pretreatment on microstructure of microalgal cells were investigated through scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Effect of treatment on lipid extraction was also studied. Microalgal cell walls were distorted after steam pretreatment due to the hydrolysis of organic macromolecules contained in cell wall. Maximum curvature was increased from 1.88 × 10~(-6) m~(-1) to 1.43 × 10~(-7) m~(-1) after treatment with the steam at 130 ℃. The fractal dimension of microalgal cells increased from 1.25 to 1.30 after pretreatment for 15 min, and further increased to 1.47 when the pretreatment time was increased to 60 min. Increased steam pretreatment temperature and time enhanced the hydrolysis of organic macromolecules, and finally destroyed microalgal cell walls at pretreatment temperature of 130 ℃ and pretreatment time of 60 min. Lipid extracted from wet microalgal was significantly increased (2.1-fold) after pretreatment.
Tungsten and phosphate polyanion co-doping of Ni-ultrahigh cathodes greatly enhancing crystal structure and interface stability

The Ni-ultrahigh cathode material is one of the best choices for further increasing energy–density of lithium-ion batteries (LIBs), but they generally suffer from the poor structure stability and rapid capacity fade. Herein, the tungsten and phosphate polyanion co-doped LiNi_(0.9)Co_(0.1)O_2cathode materials are successfully fabricated in terms of Li(Ni_(0.9)Co_(0.1))_(1–x)W_xO_(2–4)y(PO_4)_y by the precursor modification and subsequent annealing. The higher bonding energy of WAO (672 kJ·mol~(-1)) can extremely stabilize the lattice oxygen of Ni-rich oxides compared with NiAO (391.6 kJ·mol~(-1)) and CoAO (368 kJ·mol~(-1)). Meanwhile, the stronger bonding of NiA(PO_4~(3–)) vs. NiAO could fix Ni cations in the transition metal layer, and hence suppressing the Li/Ni disorder during the charge/discharge process. Therefore, the optimized Li (Ni_(0.9)Co_(0.1))_(0.99)W_(0.01)O_(1.96)(PO_4)_(0.01) delivers a remarkably extended cycling life with 95.1% retention of its initial capacity of 207.4 mA·h·g~(-1) at 0.2 C after 200 cycles. Meantime, the heteroatoms doping does not sacrifice the specific capacity even at different rates.
Stable interfaces constructed by concentrated ether electrolytes to render robust lithium metal batteries

Lithium metal batteries (LMBs) are highly considered as promising candidates for next-generation energy storage systems. However, routine electrolytes cannot tolerate the high potential at cathodes and low potential at anodes simultaneously, leading to severe interfacial reactions. Herein, a highly concentrated electrolyte (HCE) region trapped in porous carbon coating layer is adopted to form a stable and highly conductive solid electrolyte interphase (SEI) on Li metal surface. The protected Li metal anode can potentially match the high-voltage cathode in ester electrolytes. Synergistically, this ingenious design promises high-voltage-resistant interfaces at cathodes and stable SEI with abundance of inorganic components at anodes simultaneously in high-voltage LMBs. The feasibility of this interface-regulation strategy is demonstrated in Li | LiFePO_4 batteries, realizing a lifespan twice as long as the routine cells, with a huge capacity retention enhancement from 46.4% to 88.7% after 100 cycles. This contribution proof-ofconcepts the emerging principles on the formation and regulation of stable electrode/electrolyte interfaces in the cathode and anode simultaneously towards the next-generation high-energy–density batteries.
Structural Basis of RACK7 PHD Domain to Read a Pediatric Glioblastoma-Associated Histone Mutation H3.3G34R

Histone point mutations, including missense mutations on histone H3 at positions 27 (K27M), 34 (G34R/V, G34W, G34L) and 36 (K36M), were identified as potential cancer driver mutations. H3.3G34R/V mutations account for pediatric glioblastomas (GBM). RACK7 (also known as ZMYND8, PRKCBP1) was recently reported to specifically bind H3.3G34R through its PHD (plant homedomain) domain (PHD~(RACK7) ) in vitro and in H3.3G34R pediatric glioblastoma cells, playing key roles in H3.3G34R-mediated gene transcription. Herein, we provided both biochemical and NMR structural evidences that PHD~(RACK7) recognized histone H3.3G34R mutant via a mechanism distinct from all other reported PHD domains. Except the reported residue D104, two new sites D108 and L121 of PHD~(RACK7) were found necessary for the interactions between PHD~(RACK7) and histone H3.3G34R peptide. Our results provided a potential molecular basis for pediatric GBM driven by the H3.3G34R mutation.
Estimating genetic parameters with molecular relatedness and pedigree reconstruction for growth traits in early mixed breeding of juvenile turbot

An introduced turbot population was used to establish families and to estimate genetic parameters of the offspring. However, there is a lack of pedigree information, and common environmental effects can be introduced when each full-sib family is raised in a single tank. Therefore, in the genetic evaluation, SSRs (simple sequence repeats) were used to reconstruct the pedigree and to calculate molecular relatedness between individuals, and the early mixed-family culture model was used to remove the impact of the common environmental effects. After 100 d of early mixed culture, twenty SSRs were used to cluster 20 families and to calculate paired molecular relationships (n=880). Additive genetic matrices were constructed using molecular relatedness (MR) and pedigree reconstruction (PR) and were then applied to the same animal model to estimate genetic parameters. Based on PR, the heritabilities for body weight and body length were 0.214±0.124 and 0.117±0.141, and based on MR they were 0.101±0.031 and 0.102±0.034, respectively. Cross validation showed that the accuracies of the estimated breeding values based on MR (body weight and body length of 0.717±0.045 and 0.629±0.141, respectively) were higher than those of PR (body weight and body length of 0.692±0.052 and 0.615±0.060, respectively). The MR method ensure availability of all genotyped selection candidates, thereby improving the accuracy of the breeding value estimation.

轮状病毒NSP2与动力蛋白中间链相互作用介导其病毒质的形成

轮状病毒(Rotavirus,RV)是导致儿童、仔猪和许多其它幼年动物严重脱水性胃肠炎的病原之一。尽管在医疗卫生系统和兽医领域已开展了十余年的rV疫苗的免疫工作,但它仍持续威胁低收入国家儿童的健康,同时也给养猪业造成严重的经济损失。因此急需深入了解RV的复制特性,开发有效防控RV感染的策略。RV复制的主要场所为病毒质,它的形成对病毒的有效复制尤为重要。研究显示RV病毒质的形成与微管稳定性有关,且依赖微管的胞质动力蛋白(Dynein)转运参与多种病毒复制,但依赖微管的Dynein转运是否影响RV的复制及其病毒质的形成尚不清楚。
