Abstract Low insulation resistivity is a key factor limiting the practical application of colossal permittivity (CP) ceramics in electronic components. In this study, BaTiO 3 –0.01Ta 2 O 5 – x Al (BTA , = 0.005, 0.01, 0.015, 0.02) CP with high resistance were successfully prepared by sintering N . particular, BTA0.015 ceramic exhibits ( ε r 2.01 × 10 1 kHz), low dielectric loss (tan δ 0.044, ρ v 1.4 9 Ω cm, DC voltage (DC) 100 V), and superior frequency thermal stability (20 Hz–1 MHz, room...
Understanding the impact of climate change on distribution marine species is vital importance for sustainable development fisheries. In this study, an ensemble model employed to predict potential Japanese jack mackerel (Trachurus japonicus) in Northern South China Sea (NSCS) under current conditions and three future scenarios (IPCC Representative Concentration Pathways RCP126, RCP245, RCP585). The incorporates environmental variables including sea surface salinity (SSS), height above geoid...
Ultrahigh recoverable energy storage density ( W rec = 4.41 J cm −3 ) and efficiency η 88%) at low electric field (210 kV −1 ), over wide frequency (10–100 Hz) temperature (20–200 °C) were achieved simultaneously for 0.85Bi 0.5 Na TiO 3 -0.15Ca(Nb Al )O ceramics.
The nanodiamond–graphene hybrid material (ND@G) exhibits superior catalytic activity comparable to Au/C catalysts due abundant surface defects.
The development of ceramic capacitors featuring high reliability and superior comprehensive performance is vital for practical applications in medium electric fields.
Abstract While the issue of construction waste siege is becoming increasingly serious, road industry also facing problem sand and stone materials shortage, adding to base can effectively help address both issues. In this work, effects 0–9.5 9.5–37.5 mm recycled aggregate (RCWA) content on mechanical properties cement-stabilized macadam (CSM) mixed with RCWA were investigated, optimal that allows for a strength not lower than ordinary CSM determined. Here, growth law was studied, while...
In order to study the physicochemical and nutritional characteristics of kiwifruit varieties, 14 kiwifruits from different species with flesh colors were selected for research. The pectin content was significantly higher in green-fleshed than those red-fleshed yellow-fleshed kiwifruits. Red-fleshed had highest total flavonoid content, A. eriantha chlorophyll a b carotenoid content. energy carbohydrate contents lower kiwifruit. Moreover, protein chinensis var. deliciosa other species. vitamin...
Abstract The environment‐friendly materials exhibiting colossal permittivity play an increasingly important role in the electronics industry. In this work, (Tb 0.5 Ta ) x Ti 1− O 2 ( = 0, 0.005, 0.01, 0.02, and 0.04) ceramics with new defect clusters were fabricated to enhance dielectric response. Significantly, all ceramic samples exhibit large constants ε r > 10 4 ), whereas 0.005 exhibits ultralow loss (tan δ of about 0.008 at room temperature 1 kHz. origins its excellent properties...
A nickel-catalyzed regioselective cyclotrimerization of alkynes provides straightforward access to 1,2,4- or 1,3,5-trisubstituted benzenes. This protocol features the advantages broad substrate scope and easily controllable regioselectivity.
High dielectric loss and poor temperature stability are the current barriers to application of materials. In present work, we synthesized a system acceptor Gd3+ donor Ta5+ co-doped (Gd0.5Ta0.5)xTi1-xO2 (GTTOx, x = 0, 0.01, 0.02, 0.04, 0.06) ceramics enhance response. It was found that colossal permittivity (CP, 2.65 × 104@1 kHz, 2.37 MHz), very low (tanδ, [email protected] good frequency (20–106 Hz) (RT–250 °C, Δε′ (T)/ε′30 < ± 15%, at 1 kHz) were achieved simultaneously in GTTO0.01 ceramic....

Largehead hairtail Trichiurus japonicus is a major commercial fish species in the Beibu Gulf of northwestern South China Sea. Despite much effort to protect fishery resource, current stock T. overexploited. As impacts climate change unfold globally, seasonal changes distribution largehead have not yet been clarified. Maximum entropy model based on mixed layer depth and salinity were projected onto habitat under scenario three different Representative Concentration Pathways (126, 370, 585)...
Excipient emulsions were prepared using different emulsifiers (pectin and sodium caseinate, individually or compositely) to study the emulsifying properties their co-digested effects on retention bioaccessibility of carotenoids in mandarin juice, which is a good source people's diet. Results showed that both pectin (PC) pectin-sodium caseinate (PC-SC) emulsion significantly increased with depending polymer concentration. Whether for PC PC-SC emulsion, lower content accompanied viscosity...
