Summary: The present Highlight paper summarises the reported works on the effect of sulfur and nitrogen doping on graphene nanoplatelets for high capacity electrodes in solid-state rechargeable energy storage devices. Lithium-ion batteries provide high power density but are limited by the low electrical conductivity of the anode materials. By designing high-power and stable structures, the capacity and kinetic balance between the anode and cathode can be increased. Graphene nanoplatelets have been widely studied as anode materials due to their unique structure and outstanding electrochemical properties.

Summary: The utilization of van der Waals gaps in layered materials as nanofluidic channels has sparked great interest. An approach using compressive instability in Zr-doped GO thin films is demonstrated to rotate nanosheets to high angles, creating wrinkle patterns that result in near-vertically aligned nanochannels. These robust nanofluidic devices significantly reduce fluid path-length while maintaining high selectivity for water over non-polar molecules characteristic of GO interlayer nanochannels.

Summary: Chemical doping strategy for organic semiconductors targeting crystallographic step edges leads to significant improvement in electron transport properties, with a tenfold increase in electron mobility and a switch from thermally activated to band-like behaviour. This approach provides evidence for doping-induced space charge and suggests new site-specific doping strategies for organic semiconductors, deviating from traditional randomly distributed substitutional impurities. The presence of doping-induced electron atmospheres in organic systems is confirmed, aligning with expectations from conventional solid-state theory.

Summary: By co-depositing chemical solutes with two-dimensional nanosheets, nanosheet-molecular heterostructures can be formed, allowing for controlled release of intercalated molecular agents. Experimental results demonstrate that diffusion coefficients in layered solids are significantly lower due to nanochannel confinement, aiding in the ability of 2D materials to control and extend release over useful time scales. In-plane texturing of heterostructured films through compressive wrinkling or crumpling proves to be a useful design tool in controlling release rates for specific film types.

Summary: There is a growing demand for biodegradable alternatives to non-degradable microplastics in various industries. In this study, the authors demonstrate the microencapsulation of active substances in silk fibroin by adjusting the protein's protonation and chain relaxation. The size of the silk fibroin micelles can be tuned, enabling the manufacturing of microcapsules with various morphologies and structures. The degradation kinetics and sustained release of soluble and insoluble payloads are controlled by modulating the fibroin's beta-sheet content. The microencapsulation of a commonly used herbicide in silk fibroin significantly reduces its burst release, and a greenhouse trial shows reduced crop injury compared to the non-encapsulated version.

Summary: There is an urgent need to find new materials for use in the food, water, and agriculture industries that are biodegradable, have a sustainable life cycle, and are sourced at scale. In this study, the degradation of regenerated silk fibroin (SF) in different soil and water environments is investigated. The research shows that the degradation of SF is influenced by factors such as SF polymorphism, ionic strength, and the presence of microorganisms. It is found that microbial activity is a key driver for the degradation of silk and that the degradation rate can be controlled through material design and regulation of the interaction with environmental microorganisms.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
