van der Waals layered metal chalcogenide Bi2Te3 has shown exceptional capacity and rate capability in alkali-ion batteries but the underlying reaction mechanism with Li+, Na+, K+ remains undiscovered. It is unexpected that Na+ electrochemistry outperforms Li+ at high current densities. Here, situ transmission electron microscopy used to uncover nanoscale transformations during lithiation, sodiation, potassiation, which follows two-step conversion alloying reactions three-step...
Abstract Advances in liquid phase transmission electron microscopy (LP‐TEM) have enabled the monitoring of polymer dynamics solution at nanoscale, but radiolytic damage during LP‐TEM imaging limits its routine use science. This study focuses on understanding, mimicking, and mitigating observed functional polymers LP‐TEM. It is quantitatively demonstrated how occurs across all conceivable (LP‐)TEM environments, key characteristics differences between degradation water vapor are elucidated....
Polymersomes with surface-integrated nanoparticles, in which a smaller sphere is attached to larger capsule, are typically formed through complex processes like membrane deformation, polymerization, or functionalization. This complexity restricts facile application of this unusual topology, for example drug delivery nanomotor science. Our study introduces robust method crafting polymersomes nanoparticles using hierarchical phase separation approach. By co-assembling block copolymers aromatic...
The search for Kitaev's quantum spin liquid (KQSL) state in real materials has recently expanded with the prediction that honeycomb lattices of divalent, high-spin cobalt ions could host dominant bond-dependent exchange interactions required to stabilize elusive entangled state. layered Na$_3$Co$_2$SbO$_6$ been singled out as a leading candidate provided trigonal crystal field acting on Co $3d$ orbitals, which enhances non-Kitaev between $J_{\rm eff}=\frac{1}{2}$ spin-orbital pseudospins, is...
Biomimetic artificial vision is receiving significant attention nowadays, particularly for the development of neuromorphic electronic devices, intelligence, and microrobotics. Nevertheless, color recognition, most critical function, missed in current research due to difficulty downscaling prevailing sensing devices. Conventional sensors typically adopt a lateral channel layout consume large amount physical space, whereas compact designs suffer from an unsatisfactory detection accuracy. In...

The research and development of materials for energy applications such as rechargeable batteries catalysts heavily rely on advanced characterizations.Unfortunately, many those are sensitive to air, moisture, high temperature, electron beam, severely limiting the effectiveness currently available characterization methods.For example, Li metal has been widely recognized "holy grail" all anode because its capacity low voltage that can potentially be used in nextgeneration including Li-S battery...
The lack of high-performance cathode catalysts is a salient issue that bedeviled the commercialization protonic ceramic fuel cells (PCFCs). Here, we report remarkable electrocatalytic activity and stability enhancement electrodes by engineering coupled nanocomposite. as-prepared Pr0.3(Ba0.5Sr0.5)0.7Co0.8Fe0.2O3−δ nanocomposite possesses bulk cubic phase on which homogeneous intimate orthorhombic PrCo0.5Fe0.5O3−δ nanoparticles are uniformly decorated.

Abstract Garnet‐type Li 7 La 3 Zr 2 O 12 (LLZO) solid‐state electrolytes hold great promise for the next‐generation all‐solid‐state batteries. An in‐depth understanding of phase transformation during synthetic processes is required better control crystallinity and improvement ionic conductivity LLZO. Herein, pathways associated surface amorphization are comparatively investigated sol–gel syntheses LLZO using in situ heating transmission electron microscopy (TEM). The combined ex X‐ray...
