The use of metal-organic frameworks(MOFs)as solid adsorption materials for carbon capture is promising,but achieving efficient and reversible adsorption with a balance of capacity and selectivity for carbon dioxide(CO_(2))over N_(2) remains a challenge.To take full advantage of the strong channel traffic and robustness of MOFs with relatively small pores,it is highly necessary to employ a defect-engineering strategy to construct a broader channel structure that can facilitate the loading of functional motif-rich amino acids(AAs).This strategy can greatly enhance the CO_(2) adsorption performance of MOF.In this study,motif-rich amino acids are loaded into the defective and robust porous frameworks via combined defect-engineering and post-synthetic methods.The defective Zr/Hf-MOF-808s modified with AAs,especially for the 18 mol%4-nitroisophthalic acid,generated defective products allowing for the loading of L-serine(L-Ser).This modification resulted in a significant improvement in both the adsorption capacity(248%improvement at 298 K,100 kPa)and the selectivity of CO_(2)/N_(2) using the ideal adsorbed solution theory(IAST),with the selectivity increasing to 120.55 and 38.27 at 15 and 100 kPa,respectively,while maintaining good cycling performance.Density functional theory(DFT)simulation,CO_(2) temperature-programmed desorption(CO_(2)-TPD),and in situ Fourier transform infrared spectroscopy(FTIR)were further employed to have a better understanding of the enhanced CO_(2) adsorption capacity.Interestingly,unlike the AAs loaded pristine MOF-808s that showed the best CO_(2) adsorption capacity with the loading of short and small glycine(Gly),the broadened channel size in our work enables the loading of functional motif-rich L-serine,which brings more active binding sites,improving CO_(2) adsorption.

In history,semiconductor-metal-semiconductor transistor(SMST)was proposed for frequency improvement.However,a general fabrication method is still missing due to the unsolved technological problem of deposition of a general crystalline semiconductor on metal,and a thinner metal base is also difficult to be fabricated with high quality.Recently,due to the atomic thickness of graphene,the concept of semiconductor-graphene-semiconductor transistor(SGST)has emerged which leads to the renaissance of SMST,however the experimental study is in its infancy.In this letter,SMST and SGST are fabricated using Si membrane transfer.It is found the common base current gain can be improved from about 0.5%in a Si-Au-Si transistor to about 1%in a Si-Gr-Ge one,and to above 10%in a Si-Gr-Si one,which is attributed to both the ultra-thin thickness and the quantum capacitance effect of graphene.

Objectives We aimed to evaluate the risk factors for moderate-to-severe bronchopulmonary dysplasia(BPD)and focus on discussing its relationship with the duration of initial invasive mechanical ventilation(IMV)in very preterm neonates less than 32 weeks of gestational age(GA).Methods We performed a prospective cohort study involving infants born at 23–31 weeks of GA who were admitted to 47 different neonatal intensive care unit(NICU)hospitals in China from January 2018 to December 2021.Patient data were obtained from the Sina-northern Neonatal Network(SNN)Database.Results We identified 6538 very preterm infants,of whom 49.5%(3236/6538)received initial IMV support,and 12.6%(823/6538)were diagnosed with moderate-to-severe BPD symptoms.The median duration of initial IMV in the moderateto-severe BPD group was 26(17–41)days,while in the no or mild BPD group,it was 6(3–10)days.The incidence rate of moderate-to-severe BPD and the median duration of initial IMV were quite different across different GAs.Multivariable logistic regression analysis showed that the onset of moderate-to-severe BPD was significantly associated with the duration of initial IMV[adjusted odds ratio(AOR):1.97;95%confidence interval(CI):1.10–2.67],late-onset neonatal sepsis(LONS),and patent ductus arteriosus(PDA).Conclusion In this multicenter cohort study,the duration of initial IMV was still relatively long in very premature infants,and the longer duration of initial IMV accounts for the increased risk of moderate-to-severe BPD.

Acta Metallurgica Sinica(English Letters) 2019年第12期32卷 1549-1564页

This study examines the relationship among cooling rate,microstructure and mechanical properties of a sand-casted Al-5.0 Mg-0.6 Mn-0.25 Ce(wt%)alloy subjected to T4 heat treatment(430℃×12 h+natural aging for 5 days),and the tested alloys with wall thickness varying from 5 to 50 mm were prepared.The results show that as the cooling rate increases from0.22 to 7.65 K/s,the average secondary dendritic arm spacing(SDAS,λ2)decreases from 94.8 to 27.3μm.The relation between SDAS and cooling rate can be expressed by an equation:λ2=53.0 Rc-0345.Additionally,an increase in cooling rate was shown not only to reduce the amount of the secondary phases,but also to promote the transition from Al10 Mn2 Ce toα-Al24(Mn,Fe)6Si2 phase.Tensile tests show that as the cooling rate increases from 0.22 to 7.65 K/s,the ultimate tensile strength(UTS)increases from 146.3 to 241.0 MPa and the elongation(EL)increases sharply from 4.4 to 12.2%for the ascast alloys.Relations of UTS and EL with SDAS were determined,and both the UTS and EL increase linearly with(1/λ2)0.5and that these changes can be explained by strengthening mechanisms.Most eutectic Al3Mg2 phases were dissolved during T4 treatment,which in turn further improve the YS,UTS and EL.However,the increment percent of YS,UTS and EL is affected by the cooling rate.

Ototoxic destruction by co-administration of kanamycin and ethacrynic acid in rats

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2011年第10期12卷 853-861页

It is well known that ethacrynic acid (EA) can potentiate the ototoxicity of aminoglycoside antibiotics (AmAn) such as kanamycin (KM),if they were applied at the same time.Currently,to create the model of EA-KMinduced cochlear lesion in rats,adult rats received a single injection of EA (75 mg/kg,intravenous injection),or followed immediately by KM (500 mg/kg,intramuscular injection).The hearing function was assessed by auditory brainstem response (ABR) measurement in response to click and/or tone bursts at 4,8,12,16,20,24,and 32 kHz.The static microcirculation status in the stria vascularis after a single EA injection was evaluated with eosin staining.The pathological changes in cochlear and vestibular hair cells were also quantified after co-administration of EA and KM.After a single EA injection,blood flow in vessels supplying the stria vascularis rapidly diminished.However,the blood supply to the cochlear lateral wall partially recovered 5 h after EA treatment.Threshold changes in ABR were basically parallel to the microcirculation changes in stria vascularis after single EA treatment.Importantly,disposable co-administration of EA and KM resulted in a permanent hearing loss and severe damage to the cochlear hair cells,but spared the vestibular hair cells.Since the cochlear lateral wall is the important part of the blood-cochlea barrier,EA-induced anoxic damage to the epithelium of stria vascularis may enhance the entry of KM to the cochlea.Thus,experimental animal model of selective cochlear damage with normal vestibular systems can be reliably created through co-administration of EA and KM.

This study investigates the eff ect of solution treatment(at 470°C for 0–48 h)on the microstructural evolution,tensile properties,and impact properties of an Al–5.0Mg–3.0Zn–1.0Cu(wt%)alloy prepared by permanent gravity casting.The results show that the as-cast microstructure consists ofα-Al dendrites and a network-like pattern of T-Mg32(AlZnCu)49 phases.Most of the T-phases were dissolved within 24 h at 470℃;and a further prolonging of solution time resulted in a rapid growth ofα-Al grains.No transformation from the T-phase to the S-Al2CuMg phase was discovered in this alloy.Both the tensile properties and impact toughness increased quickly,reached a maximum peak value,and decreased gradually as the solution treatment proceeded.The impact toughness is more closely related to the elongation,and the relationship between impact toughness and elongation appears to obey an equation:IT=8.43 EL-3.46.After optimal solution treatment at 470℃for 24 h,this alloy exhibits excellent mechanical properties with the ultimate tensile strength,yield strength,elongation and impact toughness being 431.6 MPa,270.1 MPa,19.4%and 154.7 kJ/m^(2),which are comparable to that of a wrought Al–6.0 Mg–0.7 Mn alloy(5E06,a 5 xxx aluminum alloy).Due to its excellent comprehensive combination of mechanical properties,this cast alloy has high potential for use in components which require medium strength,high ductility and high toughness.

Petroleum Science 2024年第1期21卷 674-682页

Synergic catalytic effect between active sites and supports greatly determines the catalytic activity for the aerobic oxidative desulfurization of fuel oils.In this work,Ni-doped Co-based bimetallic metal-organic framework(CoNi-MOF)is fabricated to disperse N-hydroxyphthalimide(NHPI),in which the whole catalyst provides plentiful synergic catalytic effect to improve the performance of oxidative desulfurization(ODS).As a bimetallic MOF,the second metal Ni doping results in the flower-like morphology and the modification of electronic properties,which ensure the exposure of NHPI and strengthen the synergistic effect of the overall catalyst.Compared with the monometallic Co-MOF and naked NHPI,the NHPI@CoNi-MOF triggers the efficient activation of molecular oxygen and improves the ODS performance without an initiator.The sulfur removal of dibenzothiophene-based model oil reaches 96.4%over the NHPI@CoNi-MOF catalyst in 8 h of reaction.Furthermore,the catalytic product of this aerobic ODS reaction is sulfone,which is adsorbed on the catalyst surface due to the difference in polarity.This work provides new insight and strategy for the design of a strong synergic catalytic effect between NHPI and bimetallic supports toward high-activity aerobic ODS materials.

An overview and perspective of identifying lunar craters

The spatiotemporal evolution of lunar impact craters is crucial for investigating lunar interior structure,internal and external dynamic processes,and interplanetary impact history.Advances in lunar crater identification are reviewed based on topography and gravity data,and the features and mechanisms of topographic or buried craters are analyzed regarding morphology,gravity anomalies,gravity gradients,and the underlying crust-mantle interface relief.Based on the compiled crater catalog,the early lunar impact flux and thermal evolution are further discussed according to the basin ages and their interior structures.For some ancient impact basins,the crater size-frequency distribution measurements revealed age discrepancies from previous studies,suggesting that the lunar late heavy bombardment event started at~3.95 Ga.The degraded bulge structures of the crust-mantle interface beneath mare basins reveal that these basins formed on the lunar crust surface under high-temperature conditions and underwent prolonged relaxation compared to highland basins.Finally,we reveal that the up-to-date identification of lunar buried craters remains inaccurate and incomplete,preventing us from accurately reconstructing lunar and interplanetary impact histories.Therefore,we propose that a gravity model constructed using localized orthogonal basis functions can be useful for identifying lunar craters.
