Ultraviolet‐Durable Flexible Nonfullerene Organic Solar Cells Realized by a Hybrid Nanostructured Transparent Electrode

Tao Xu, Chunliu Gong, Shuanglong Wang, Hong Lian, Weixia Lan, Gaëtan Lévêque, B. Grandidier, Jerome Plain, Renaud Bachelot, Bin Wei, Furong Zhu

A significant enhancement in ultraviolet (UV)-durable indium tin oxide (ITO)-free flexible nonfullerene organic solar cells (OSCs) is demonstrated using a hybrid nanostructured flexible transparent electrode (FTE), comprising a mixture of 0D silver nanoparticles, 1D Ag nanowires, and 2D exfoliated...

The limits of edge bead planarization and surface levelling in spin-coated liquid films

S. Arscott

A model is presented here to predict fluid reflow in a viscous liquid film having time-dependent physical properties. The model is applied to the practical example of the reflow planarization (surface levelling) of 'edge bead' features resulting from the spin coating process. During the...

Power Domain NOMA Without SIC in Downlink CSS-Based LoRa Networks

Angesom Ataklity Tesfay, Eric Pierre Simon, Ido Nevat, Laurent Clavier

Low Power Wide Area Network, such as LoRa is one of the main building blocks of the Internet of Things. One of the main issues is to scale up the number of devices and one strong limitation comes from the downlink communication. In fact, the access point is constrained by the duty cycle, therefore...

Friction-induced energy losses in mechanical contacts subject to random vibrations

Vladislav Aleshin, Antonio Papangelo

In this paper, we apply the previously developed Method of Memory Diagrams (MMD) to the description of an axisymmetric mechanical contact with friction subject to random vibrations. The MMD belongs to a family of semi-analytical methods of contact mechanics originating from the classical Cattaneo-...

Anomaly Detection in Surveillance Videos by Future Appearance-motion Prediction

Tuan-Hung Vu, Sebastien Ambellouis, Jacques Boonaert, Abdelmalik Taleb-Ahmed

Anomaly detection in surveillance videos is the identification of rare events which produce different features from normal events. In this paper, we present a survey about the progress of anomaly detection techniques and introduce our proposed framework to tackle this very challenging objective....

Augmenting sensitivity of surface plasmon resonance (SPR) sensors with the aid of anti-reflective coatings (ARCs)

Das Cm, Ouyang Ql, Kang Lx, Guo Y, Dinh Xq, P. Coquet, Yong Kt

Surface plasmon resonance (SPR)-based biosensors are an integral and indispensable aspect of present-day pathology, owing to its efficient real-time and label-free detection capabilities. Enhancing the sensitivity of these sensors is of paramount importance as it indirectly affects the detection...
