Elastic Graphene‐Shell Architectures Enable Stress Regulation in High‐Capacity Lithium‐Ion Battery Electrodes

Advanced Science, EarlyView.
In this study, we developed elastic hollow graphene spheres (GS) that serve as a pore‐engineering additive. This strategy enables the direct fabrication of porous electrodes, effectively mitigating volume expansion and mechanical stress in silicon‐based anodes during cycling without compromising active material or increasing production costs.

Self‐Assembled Pt(II) Complexes Boost Up Stem Cell Proliferation and Accelerate Metamorphosis in Living Organisms

Angewandte Chemie, EarlyView.
Pt1, an organometallic platinum‐based complex, act as a modulator of redox homeostasis in cnidarians, regulating cellular functions and life‐cycle dynamics. In Nematostella vectensis, it mitigates oxidative stress, strengthens detox systems and accelerates development.

S@NiS Hollow Spheres as Cathode Materials for LithiumSulfur Batteries

International Journal of Electrochemical Science, 2019
Severe capacity fading substantially hinders the employment of lithium-sulfur batteries in the electric vehicles. This is primarily due to the shuttle effect of the polysulfide in the electrolyte. Therefore, the most efficient method to improve the cycle

Hydrogen Production from Ammonia Electrochemical Cracking

Advanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Overcoming the *H‐NOx Coupling Bottleneck via Palladium‐Enabled Relay Catalysis on CuCo2O4 Toward Ampere‐Level Nitrate‐to‐Ammonia

Advanced Science, EarlyView.
Pd‐doped hollow spiny CuCo2O4 microspheres deliver ampere‐level electrocatalytic nitrate to ammonia. Cu and Co sites undergo relay catalysis for sequential nitrate reduction, while Pd accelerates water dissociation to supply abundant active hydrogen (*H).
