Ich brauch mal eben Hilfe von den Chemiker*innen, Materialwissenschaftler*innen oder schlicht 3D-Druck-Nerds hier: Für ein Display sollen Schilder für die Materialien PLA, PETG und TPU gedruckt werden, auf denen auch die Struktur der Stoffe zu sehen sein soll. Leider bin ich kein Experte darin, ob die Abbildungen, die jemand rausgesucht hat, auch tatsächlich korrekt sind. Kann da jemand helfen? (darf gern geboostet werden)

From Principles to Practice: A Systematic Study of LLM Serving on Multi-core NPUs
With the widespread adoption of Large Language Models (LLMs), the demand for high-performance LLM inference services continues to grow. To meet this demand, a growing number of AI accelerators have been proposed, such as Google TPU, Huawei NPU, Graphcore IPU, and Cerebras WSE, etc. Most of these accelerators adopt multi-core architectures to achieve enhanced scalability, but lack the flexibility of SIMT architectures. Therefore, without careful configuration of the hardware architecture, as wel…

Enhanced intraband absorption in two-step photon upconversion solar cells with a double-tunnel-junction structure
Two-step photon upconversion solar cells (TPU-SCs) belong to the class of solar cells that in principle can exceed the Shockley--Queisser limit for single-junction solar cells. A TPU-SC basically consists of a wide-gap and a narrow-gap semiconductor layer, where intraband absorption of infrared (IR) photons by electrons accumulated at the conduction-band-edge discontinuity leads to an increase in the output current and voltage. This IR-induced upconversion process enables a better utilization o…
