Flexible aqueous zinc-ion batteries(AZIBs)with air-recharging capability are a promising self-powered system applied in future wearable electronics.It is desired to develop high-capacity air-rechargeable AZIBs.Herein,we developed a flexible AZIB with air-recharging capability based on trinitrohexaazatrinaphthylene(TNHATN)cathode and a ZnSO_(4)electrolyte.The flexible Zn//TNHATN battery exhibits high volumetric energy density(21.36 mWh/cm^3)and excellent mechanical flexibility.Impressing,the discharged flexible Zn//TNHATN battery can be chemical self-charged via the redox reaction between TNHATN cathode and O_(2)from the air.After oxidation in air for 15 h,such flexible Zn//TNHATN battery can deliver a high specific capacity of 320 mAh/g at 0.5 A/g,displaying excellent air-recharging capability.Notably,this flexible Zn//TNHATN battery also works well in chemical or/and galvanostatic charging mixed modes,showing reusability.This work provides a new insight for designing flexible aqueous self-powered systems.

The full-field multiaxial strain measurement is highly desired for application of structural monitoring but still challenging,especially when the manufacturing and assembling for largearea sensing devices is quite difficult.Compared with the traditional procedure of gluing commercial strain gauges on the structure surfaces for strain monitoring,the recently developed Direct-Ink-Writing(DIW)technology provides a feasible way to directly print sensors on the structure.However,there are still crucial issues in the design and printing strategies to be probed and improved.Therefore,in this work,we propose an integrated strategy from layered circuit scheme to rapid manufacturing of strain rosette sensor array based on the DIW technology.Benefit from the innovative design with simplified circuit layout and the advantages of DIW for printing multilayer structures,here we achieve optimization design principle for strain rosette sensor array with scalable circuit layout,which enable a hierarchical printing strategy for multiaxial strain monitoring in large scale or multiple domains.The strategy is highly expected to adapt for the emerging requirement in various applications such as integrated soft electronics,nondestructive testing and small-batch medical devices.

Macular corneal dystrophy(MCD)is a progressive,bilateral stromal dystrophic disease that arises from mutations in carbohydrate sulfotransferase 6(CHST6).Corneal transplantation is the ultimate therapeutic solution for MCD patients.Unfortunately,postoperative recurrence remains a significant challenge.We conducted a retrospective review of a clinical cohort comprising 102 MCD patients with 124 eyes that underwent either penetrating keratoplasty(PKP)or deep anterior lamellar keratoplasty(DALK).Our results revealed that the recurrence rate was nearly three times higher in the DALK group(39.13%,9/23 eyes)compared with the PKP group(10.89%,11/101 eyes),suggesting that surgical replacement of the corneal endothelium for treating MCD is advisable to prevent postoperative recurrence.Our experimental data confirmed the robust m RNA and protein expression of CHST6 in human corneal endothelium and the rodent homolog CHST5 in mouse endothelium.Selective knockdown of wild-type Chst5 in mouse corneal endothelium(AC^(siChst5)),but not in the corneal stroma,induced experimental MCD with similar extracellular matrix synthesis impairments and corneal thinning as observed in MCD patients.Mice carrying Chst5 point mutation also recapitulated clinical phenotypes of MCD,along with corneal endothelial abnormalities.Intracameral injection of wild-type Chst5 rescued the corneal impairments in AC^(siChst5)mice and retarded the disease progression in Chst5 mutant mice.Overall,our study provides new mechanistic insights and therapeutic approaches for MCD treatment by highlighting the role of corneal endothelium in MCD development.

Hydrogen storage alloys(HSAs)are attracting widespread interest in the nuclear industry because of the generation of stable metal hydrides after tritium absorption,thus effectively preventing the leakage of radioactive tritium.Commonly used HSAs in the hydrogen isotopes field are Zr2M(M=Co,Ni,Fe)alloys,metallic Pd,depleted U,and ZrCo alloy.Specifically,Zr2M(M=Co,Ni,Fe)alloys are considered promising tritium-getter materials,and metallic Pd is utilized to separate and purify hydrogen isotopes.Furthermore,depleted U and ZrCo alloy are well suited for storing and delivering hydrogen isotopes.Notably,all the aforementioned HSAs need to modulate their hydrogen storage properties for complex operating conditions.In this review,we present a comprehensive overview of the reported modification methods applied to the above alloys.Alloying is an effective amelioration method that mainly modulates the properties of HSAs by altering their local geometrical/electronic structures.Besides,microstructural modifications such as nano-sizing and nanopores have been used to increase the specific surface area and active sites of metallic Pd and ZrCo alloys for enhancing de-/hydrogenation kinetics.The combination of metallic Pd with support materials can significantly reduce the cost and enhance the pulverization resistance.Moreover,the poisoning resistance of ZrCo alloy is improved by constructing active surfaces with selective permeability.Overall,the review is constructive for better understanding the properties and mechanisms of hydrogen isotope storage alloys and provides effective guidance for future modification research.

During chronic kidney disease (CKD),alterations in bone and mineral metabolism include increased production of the hormone fibroblast growth factor 23 (FGF23) that may contribute to cardiovascular mortality.The osteocyte protein dentin matrix protein 1 (DMP1) reduces FGF23 and enhances bone mineralization,but its effects in CKD are unknown.We tested the hypothesis that DMP1 supplementation in CKD would improve bone health,prevent FGF23 elevations and minimize consequent adverse cardiovascular outcomes.We investigated DMP1 regulation and effects in wild-type (WT) mice and the Col4a3^-/- mouse model of CKD.Col4a3^-/- mice demonstrated impaired kidney function,reduced bone DMP1 expression,reduced bone mass,altered osteocyte morphology and connectivity,increased osteocyte apoptosis,increased serum FGF23,hyperphosphatemia,left ventricular hypertrophy (LVH),and reduced survival.Genetic or pharmacological supplementation of DMP1 in Col4a3^-/- mice prevented osteocyte apoptosis,preserved osteocyte networks,corrected bone mass,partially lowered FGF23 levels by attenuating NFAT-induced FGF23 transcription,and further increased serum phosphate.Despite impaired kidney function and worsened hyperphosphatemia,DMP1 prevented development of LVH and improved Col4a3^-/- survival.Our data suggest that CKD reduces DMP1 expression,whereas its restoration represents a potential therapeutic approach to lower FGF23 and improve bone and cardiac health in CKD.

It is challenging to match the mutual interactions between implant and host because the biomaterials usually cannot actively adjust their performance to the changing microenvironment.Surface potential is one of the critical factors affecting the bioactivity of biomaterials,but it is difficult to be directly controlled in vivo.Magnetic stimulation has attracted much attention due to its deep penetrability,good reliability,and convenient operability.Here,titanium dioxide(TiO_(2))nanotubes and Terfenol‐D/P(VDF‐TrFE)composite film are prepared by anodic oxidation and solution casting methods on opposite sides of a titanium sheet,respectively.Terfenol‐D magnetostrictive microparticles deform under a magnetic field,generating surface potential on the P(VDF‐TrFE)piezoelectric matrix through magneto‐electric coupling.Correspondingly,equal opposite charges are induced on the surface of TiO_(2) nanotubes.Stem cells cultured on TiO_(2) nanotubes show that cell adhesion,proliferation,and differentiation abilities can be regulated by magnetic strength,which correlates with the absorption of charged proteins.Therefore,a cascade coupling of magnetic,mechanical,electric,biochemical,and cellular effects is established.This work demonstrates the feasibility of regulating the bioactivity of biomaterials in vivo through a magnetic field.
