Abstract Summary: Novel readily soluble random low‐band‐gap conjugated copolymers (PFO–DTTP, E g ≈ 1.77–2.00 eV) derived from 9,9‐dioctylfluorene (DOF) and 2,3‐dimethyl‐5,7‐dithien‐2‐yl‐thieno[3,4‐b]pyrazine (DTTP) were prepared. The solutions the solid thin films of absorbed light 300–690 nm. Prototype photovoltaic cells state composite with copolymer PFO–DTTP30 [6,6]‐phenyl C 61 butyric acid methyl ester (PCBM) showed power conversion efficiencies up to 0.83% under an AM1.5 solar simulator...
This paper proposes a new multiple coils coupler (MCC) comprising transmitter with numerous circular auxiliary connected in series and lightweight receiver coil to ensure high anti-misalignment ability for the wireless charging system (WCS). First, proposed MCC's rationality is verified by analyzing misalignment performance of asymmetric (ACC) some coils. Furthermore, comprehensive elucidation given, outlining principle structure from magnetic field distribution mutual inductance model....

Abstract Novel poly( p ‐phenylenevinylene) (PPV) copolymers derived from 1‐methoxy‐4‐octyloxyphenylene (MOP), 2,1,3‐benzothiadiazole (BT), and trans ‐1,2‐bis(tributylstannyl)ethylene were first prepared by a palladium‐catalyzed Stille coupling reaction. The feed ratios of MOP to BT 99.5:0.5, 99:1, 95:5, 85:15, 70:30, 50:50. An efficient energy transfer the 2‐methoxy‐5‐octyloxy‐ ‐phenylenevinylene segment narrow‐band‐gap units was observed. poly(2‐methoxy‐5‐octyloxy‐...
Recently, people present higher standard of the luminance and contrast for display system, especially large UHD which increasingly demands HDR 1000 compatible. Compared with side‐emitting LED backlight, direct lit‐type backlight can provides luminance, but global control cannot satisfy high requirement power loss. In order to improve performance local dimming Mini‐LED become one best choices us. this paper, we a pixel‐level is applied 75 inch system.
Optical microscopy, TEM and SAXS reveal stable morphology at micro nanoscopic length scales.
For subspace recovery, most existing low-rank representation (LRR) models performs in the original space single-layer mode. As such, deep hierarchical information cannot be learned, which may result inaccurate recoveries for complex real data. In this paper, we explore multi-subspace recovery problem by designing a multilayer architecture latent LRR. Technically, propose new Multilayer Collabora-tive Low-Rank Representation Network model termed DeepLRR to discover features and subspaces....
