A strategy to stabilize 3D/2D perovskite heterostructures for solar cells
Hybrid perovskite solar cells (PSCs) made of organic and inorganic materials are highly promising energy solutions that could help to reduce carbon emissions worldwide. In recent years, these cells' power-conversion efficiencies (PCEs) have improved significantly,...
A new inference attack that could enable access to sensitive user data
As the use of machine learning (ML) algorithms continues to grow, computer scientists worldwide are constantly trying to identify and address ways in which these algorithms could be used maliciously or inappropriately. Due to their advanced data analysis capabilities,...
The large-area synthesis and transfer of multilayer hBN for fabricating 2D electronics
Researchers at Kyushu University, the National Institute of Advanced Industrial Science and Technology (AIST) and Osaka University in Japan have recently introduced a new strategy for synthesizing multi-layer hexagonal boron nitride (hBN), a material that could be...
Simple techniques to quantify Li plating and speed up the charging of Li-ion batteries
Lithium-ion batteries (LiBs) are among the most widespread rechargeable battery technologies, due to their high energy densities and performances. Despite their versatility and advantageous characteristics, these batteries often require specific times to charge and...
A new approach to improve robot navigation in crowded environments
While robots have become increasingly advanced over the past few years, most of them are still unable to reliably navigate very crowded spaces, such as public areas or roads in urban environments. To be implemented on a large-scale and in the smart cities of the...
Non-reciprocal acoustoelectric amplifiers for very high frequency sound waves
In recent years, teams of engineers worldwide have been trying to develop acoustic devices based on piezoelectrics (i.e., materials that can produce electricity when mechanical stress is applied to them) integrated with conventional semiconductors. These devices could...
A new AI-based tool to detect DDoS attacks
Cybercriminals are coming up with increasingly savvy ways to disrupt online services, access sensitive data or crash internet user's devices. A cyber-attack that has become very common over the past decades is the so-called Distributed Denial of Service (DDoS) attack.
A universal domain adaptation technique for remote sensing image classification
Domain adaptation approaches are techniques designed to improve the performance of computational models in specific target domains. These techniques are particularly valuable for tackling problems for which there is only a limited amount of relevant annotated data and...
Using a solidified liquid metal to build 3D flexible electronics
In recent years, engineers and material scientists have been trying to identify particularly promising materials for creating flexible electronics of different shapes and sizes. Ultimately, these electronics could be integrated in wearable devices (e.g., smart watches...
