| 1 | Interfacially stable MOF nanosheet membrane with tailored nanochannels for ultrafast and thermo-responsive nanofiltration显示文摘Two-dimensional nanosheet membranes with responsive nanochannels are appealing for controlled mass transfer/separation,but limited by everchanging thicknesses arising from unstable interfaces.Herein,an interfacially stable,thermo-responsive nanosheet membrane is assembled from twin-chain stabilized metal-organic framework(MOF)nanosheets,which function via two cyclic amide-bearing polymers,thermo-responsive poly(N-vinyl caprolactam)(PVCL)for adjusting channel size,and non-responsive polyvinylpyrrolidone for supporting constant interlayer distance.Owing to the microporosity of MOF nanosheets and controllable interface wettability,the hybrid membrane demonstrates both superior separation performance and stable thermo-responsiveness.Scattering and correlation spectroscopic analyses further corroborate the respective roles of the two polymers and reveal the microenvironment changes of nanochannels are motivated by the dehydration of PVCL chains. | Wei Jia Baohu Wu Shengtong Sun Peiyi Wu | 2020 | Nano Research2020，13，11： | 3 |
| 2 | Mechanoadaptive morphing gel electrolyte enables flexible and fast-charging Zn-ion batteries with outstanding dendrite suppression performance显示文摘The safe,flexible,and environment-friendly Zn-ion batteries have aroused great interests nowadays.Nevertheless,flagrant Zn dendrite uncontrollably grows in liquid electrolytes due to insufficient surface protection,which severely impedes the future applications of Zn-ion batteries especially at high current densities.Gel electrolytes are emerging to tackle this issue,yet the required high modulus for inhibiting dendrite growth as well as concurrent poor interfacial contact with roughened Zn electrodes are not easily reconcilable to regulate the fragile Zn/Zn^(2+) interface.Here we demonstrate,such a conflict may be defeated by using a mechanoadaptive cellulose nanofibril-based morphing gel electrolyte(MorphGE),which synergizes bulk compliance for optimizing interfacial contact as well as high modulus for suppressing dendrite formation.Moreover,by anchoring desolvated Zn^(2+) on cellulose nanofibrils,the side reactions which induce dendrite formation are also significantly reduced.As a result,the MorphGE-based symmetrical Zn-ion battery demonstrated outstanding stability for more than 100 h at the high current density of 10 mA·cm^(−2) and areal capacity of 10 mA·h·cm^(−2),and the corresponding Zn-ion battery delivered a prominent specific capacity of 100 mA·h·g^(−1) for more than 500 cycles at 20 C.The present example of engineering the mechanoadaptivity of gel electrolytes will shed light on a new pathway for designing highly safe and flexible energy storage devices. | Faqing Cao Baohu Wu Tianyu Li Shengtong Sun Yucong Jiao Peiyi Wu | 2022 | Nano Research2022，15，3： | 2 |

| 8 | Boosting the electrochromic performance of TiO_(2) nanowire film via successively evolving surface structure显示文摘Electrochromic transition metal oxides(ETMOs)are useful in energy saving devices and smart indicators.Among these ETMO candidates,titanium dioxide(TiO_(2))is intriguing for its abundance and environmental safety,but the low color efficiency and slow coloring rate are still barricades to promote its electrochromic application.Herein,we demonstrate an amorphization strategy to comprehensively enhance the performance of TiO_(2) nanowire film(TNF)via atomic layer deposition(ALD)of an additional TiO_(2) conformal layer onto TNF surface,of which the layer structure evolves successively from ordered to disordered,achieving tunable electrochromism by controlling ALD cycles.Besides the remarkable increment of charging efficiency by~35% and color efficiency by~40%,bleached transmittance rectified optical density(BTR density)and ion diffusion coefficient are boosted by~90% and over 15 times,respectively for TNF deposited with 150 cycles.A large number of self-doped Ti^(3+) defects and hydroxyl units together with order-disorder interconnections in the ALD TiO_(2) layer are responsible for the performance enhancement.The concept for successively evolving surface structure shares the feasibility of upgrading conventional ETMOs as well as designing new electrochromic materials. | Baohu Dai Changzheng Wu Yi Xie | 2021 | Science China Chemistry2021，64，5： | 0 |
| 9 | Hierarchical Network-Augmented Hydroglasses for Broadband Light Management显示文摘Light management is essential for military stealth,optical information communication,and energy-efficient buildings.However,current light management materials face challenges of limited optical modulation range and poor mechanical properties.Herein,we report a locally confined polymerization(LCP)approach to develop hierarchical network-augmented hydroglasses(HNAH)based on poly(methacrylic acid)for broadband light management as well as mechanical enhancement.The dynamic geometry of the networks ranging from nano-to micro-scale enables to manage the light wavelength over three orders of magnitude,from the ultraviolet(UV)to infrared(IR)band,and reversibly switches transmittance in the visible region.A smart hydroglass window is developed with elasticity,outstanding robustness,self-healing,notch resistance,biosafety by blocking UV radiation,and high solar energy shielding efficacy with a temperature drop of 13℃.Compared to current inorganic glasses and Plexiglas,the hydroglass not only is a promising and versatile candidate but also provides novel insights into the molecular and structural design of broadband light management and optimized mechanical properties. | Zhouyue Lei Baohu Wu Peiyi Wu | 2021 | Research2021，，1： | 0 |
