Zinc‐based batteries are emerging as promising alternatives to mainstream technologies due to their superior safety, cost‐effectiveness, and abundance of raw materials. However, zinc anodes, exhibit insufficient cycle life and low utilization in aqueous electrolytes, mainly owing to shape change and passivation. While nanostructuring of Zn anodes h...
Pulsed laser-deposited amorphous carbon nanofoams could be a potential candidate for electrochemical energy storage applications due to their properties such as ultralightweight, huge volumetric void fractions, and co-existence of sp, sp2 and sp3 carbon hybridization. It is known that the charge-storage of carbon nanostructures containing disordere...
The Front Cover highlights an investigation into film deposition by pulsed laser ablation under a background gas pressure. In their Research Article S. Ghosh, C. S. Casari and co-workers focus on nanofoams grown by ablated species directed backward with respect to the direction of expansion of the plasma plume, rather than conventionally grown nano...
Nanoporous carbon materials containing small domains of sp2-carbon with highly disordered structures are promising for supercapacitor applications. Herein, we synthesize amorphous carbon nanofoam with 98% volumetric void fraction and low mass density of around 30 mg/cm3 by pulsed laser deposition at room temperature. With the unavoidable oxygen fun...
In pulsed laser deposition, along the traditionally exploited deposition on the front‐side of the plasma‐plume, a coating forms on the surface of the target as well. For reproducibility, this residue is usually cleaned and discarded. Here we instead investigate the target‐side coated materials and employ them as a binder‐free supercapacitor electro...
While alkaline Zn batteries, like traditional rechargeable aqueous batteries, boast an advantage in terms of energy density, their progress has been hampered by concerns related to the anode. These concerns include issues like Zn dendrites, self‐corrosion, passivation, shape change, and the hydrogen evolution reaction (HER). To tackle these challen...
Manganese, showing stable oxidation states spanning from +2 to +7, gives rise to a variety of oxides (MnOx) whose exploitation in several technological fields, such as energy conversion and storage, catalysis, sensing, and environmental and biomedical engineering, is highly promising. Nevertheless, the chemical complexity and the structural richnes...
Aqueous Zn-ion batteries (AZIBs) represent a safe and sustainable technology amongst the post-lithium systems, though the poor understanding of the material behaviour at the cathode prevents the full development of efficient AZIBs. ZnMn2O4 (ZMO) has been considered one of the cathode candidates owing to its analogy to the well-established LiMn2O4 c...
Among post-lithium ion battery technologies, rechargeable chemistries with Zn anodes bear notable technological promise owing to their high theoretical energy density, lower manufacturing cost, availability of raw materials and inherent safety. However, Zn anodes, when employed in aqueous electrolytes, suffer from hydrogen evolution, passivation, a...
As renewable energy is becoming a critical energy source to meet the global demand, electrochemical energy storage devices become indispensable for the efficient energy storage and reliable supply. The electrode material is the key factor determining the energy storage capacity and the power delivery of the devices. Carbon-based materials are emerg...
In the science and technology of electrochemical energy storage, different allotropes of MnO2, fabricated with a variety of methods, are assembled into electrodes, playing the role of cathode or ORR electrocatalyst. Often, MnO2‐based cathodes are combined with Zn anodes into different types of batteries, resulting in contact between MnO2 and its el...

The applications of SERS in therapeutic drug monitoring, or other fields of analytical chemistry, require the availability of sensitive sensors and experimental approaches that can be implemented in affordable ways. In this contribution, we show the production of cost-effective SERS sensors obtained by depositing Lee-Meisel Ag colloids on filter pa...
