The abundance of solar thermal energy and the widespread demands for waste heat recovery make thermoelectric generators (TEGs) very attractive in harvesting low‐cost resources. Meanwhile, refrigeration is promising local cooling niche applications. In this context there currently a growing interest developing organic materials which are flexible, cost‐effective, eco‐friendly potentially energy‐efficient. particular, past several years have witnessed remarkable progress devices. review,...
From an environmental perspective, lead-free SnTe would be preferable for solid-state waste heat recovery if its thermoelectric figure-of-merit could brought close to that of the lead-containing chalcogenides. In this work, we studied properties nanostructured with different dopants, and found indium-doped showed extraordinarily large Seebeck coefficients cannot explained properly by conventional two-valence band model. We attributed enhancement resonant levels created indium impurities...
The mechanisms of malignant cell transformation caused by the oncogenic, chimeric nucleophosmin (NPM)/anaplastic lymphoma kinase (ALK) remain only partially understood, with most previous studies focusing mainly on impact NPM/ALK survival and proliferation. Here we report that NPM/ALK-carrying T (ALK+TCL) cells strongly express immunosuppressive cell-surface protein CD274 (PD-L1, B7-H1), as determined mRNA level. expression is strictly dependent enzymatic activity NPM/ALK, demonstrated...
Abstract Combining high energy ball‐milling and hot‐pressing, significant enhancements of the thermoelectric figure‐of‐merit ( ZT ) have been reported for p‐type Bi 0.4 Sb 1.6 Te 3 nanocomposites. However, applying same technique to n‐type 2 2.7 Se 0.3 showed no improvement on values, due anisotropic nature properties . Even though texturing was effective in improving peak from 0.85 1.04, reproducibility batch remains unsatisfactory. Here, we show that good can be achieved by introducing an...
Abstract A new series of starburst triarylamine fluorophores SBCHO, DBCHO, CZCHO, CZCN, and SBCN, that incorporate diphenylamine or carbazole as the electron donor dicyanovinyl aldehyde acceptor, has been prepared their photophysical properties are investigated. In sharp contrast to most red‐emitting dopants, which show serious aggregation‐caused quench phenomena, triphenylamine derivatives reported here unique enhanced emission in solid state upon aggregation. Organic light emitting diodes...
Thermoelectric generators, capable of directly converting heat into electricity, hold great promise for tackling the ever-increasing energy sustainability issue. The thermoelectric conversion efficiency is heavily dependent upon materials' performance that quantified by dimensionless figure-of-merit (ZT). Therefore, central issue in research materials lies continuously boosting ZT value. Although effects were discovered nineteenth century, it was only until 1950s when classic like Bi2Te3 and...
By adding aluminium (Al) into lead selenide (PbSe), we successfully prepared n-type PbSe thermoelectric materials with a figure-of-merit (ZT) of 1.3 at 850 K. Such high ZT is achieved by combination Seebeck coefficient caused very possibly the resonant states in conduction band created Al dopant and low thermal conductivity from nanosized phonon scattering centers.
In this paper we present an end-to-end speech recognition model with Transformer encoders that can be used in a streaming system. computation blocks based on self-attention are to encode both audio and label sequences independently. The activations from combined feed-forward layer compute probability distribution over the space for every combination of acoustic frame position history. This is similar Recurrent Neural Network Transducer (RNN-T) model, which uses RNNs information encoding...
Abstract A regional haze with daily PM 2.5 (fine particulate matters diameters less than µm) exceeding 500 µg/m 3 lasted for several days in January 2013 over North China, offering an opportunity to evaluate models. Observations show that inorganic aerosols (sulfate, nitrate, and ammonium) are the largest contributor during period, while sulfate shows enhancement ratio of 5.4 from clean period. The nested‐grid GEOS‐Chem model reproduces distribution simulates up 364 maximum . Yet on average,...
Bismuth telluride (Bi2Te3) and its alloys have been widely investigated as thermoelectric materials for cooling applications at around room temperature. We report a systematic study on many compounds in the Bi2Te3–Bi2Se3–Bi2S3 system. All samples were fabricated by high energy ball milling followed hot pressing. Among compounds, Bi2Te2S1 shows peak ZT ∼0.8 300 °C Bi2Se1S2 500 °C. The results show that these can be used mid-temperature power generation applications. leg efficiency of...
A direct current atmospheric pressure cold plasma microjet (PMJ) was used to produce activated water (PAW) in two generation modes above (PAW‐A) and beneath (PAW‐B) the surface. The physicochemical characteristics biological effects of them were measured respectively. Results showed that PAW‐B exhibited stronger disinfection efficiency than PAW‐A, which associated with ORP conductivity, but not pH value, temperature, H 2 O , NO 3 − or . Furthermore, cell membrane integrity potential S....
