1. Scaling of Hybrid QDs-Graphene Photodetectors to Subwavelength Dimensions 

   Kara, Gokhan; Rohner, Patrik; Wu, Erfu; et al. (2024)

   ACS PHOTONICS

   Emerging colloidal quantum dot (cQD) photodetectors currently challenge established state-of-the-art infrared photodetectors in response speed, spectral tunability, simplicity of solution processable fabrication, and integration onto curved or flexible substrates. Hybrid phototransistors based on 2D materials and cQDs, in particular, are promising due to their inherent photogain, enabling direct photosignal enhancement. The photogain is ...

2. Solid-state extrusion of nascent disentangled ultra-high molecular weight polyethylene 

   Christakopoulos, Fotis; Busato, Stephan P.; Kong, Xiang; et al. (2024)

   Polymer Engineering & Science

   Ultra-high molecular weight polyethylene (UHMWPE) stands out as the preferred material across a wide spectrum of demanding applications, thanks to its remarkable mechanical, chemical and physical attributes. Nevertheless, processing UHMWPE can be an arduous and time-consuming endeavor. Traditional melt-processing techniques, commonly employed for polymers, prove impractical due to the exceedingly high viscosity of the melt that follows ...

3. Neural Denoising for Deep-Z Monte Carlo Renderings 

   Zhang, Xianyao; Rothlin, Gerhard; Zhu, Shilin; et al. (2024)

   Computer Graphics Forum

   We present a kernel-predicting neural denoising method for path-traced deep-Z images that facilitates their usage in animation and visual effects production. Deep-Z images provide enhanced flexibility during compositing as they contain color, opacity, and other rendered data at multiple depth-resolved bins within each pixel. However, they are subject to noise, and rendering until convergence is prohibitively expensive. The current state ...

4. GENERATION OF ENTROPY WAVES BY FULLY PREMIXED FLAMES IN A NON-ADIABATIC COMBUSTOR WITH HYDROGEN ENRICHMENT 

   Eder, Alexander J.; Dharmaputra, Bayu; Desor, Marcel; et al. (2023)

   PROCEEDINGS OF ASME TURBO EXPO 2023: TURBOMACHINERY TECHNICAL CONFERENCE AND EXPOSITION, GT2023, VOL 3B

   Thermoacoustic combustion instability is a major concern in gas turbine combustors with hydrogen-enriched fuels. Unsteady combustion not only generates acoustic waves, but it may also result in ructuations of burnt gas temperature, referred to as entropy waves. They are convected by the mean row through the combustor and can cause indirect combustion noise when they are accelerated at the exit. In this work, we demonstrate that entropy ...

5. Window[1]resorcin[3]arenes: A Novel Macrocycle Able to Self-Assemble to a Catalytically Active Hexameric Cage 

   Li, Tian-Ren; Das, Chintu; Cornu, Ivan; et al. (2024)

   JACS AU

   The hexameric resorcin[4]arene capsule has been utilized as one of the most versatile supramolecular capsule catalysts. Enlarging its size would enable expansion of the substrate size scope. However, no larger catalytically active versions have been reported. Herein, we introduce a novel class of macrocycles, named window[1]resorcin[3]arene (wRS), that assemble to a cage-like hexameric host. The new host was studied by NMR, encapsulation ...
