Molybdenum disulfide (MoS2) with excellent properties has been widely reported in recent years. However, it is a great challenge to achieve p-type conductivity MoS2 because of its native stubborn n-type conductivity. Substitutional transition metal doping proved be an effective approach tune their intrinsic and enhance device performance. Herein, we report the growth Nb-doping large-area monolayer by one-step salt-assisted chemical vapor deposition method. Electrical measurements indicate...
We report and discuss how gold nanoparticles were synthesized by the reduction of hydrogen tetrachloroaurate(III) trihydrate sodium citrate in presence unmodified α-cyclodextrin (CD), β-CD, γ-CD. Gold immobilized on poly(diallyldimethylammonium) chloride (PDDA) modified glass slides to enable AFM measurements. The particle size was dependent upon type concentration cyclodextrin used as well concentration. An increase effected a shift range from 12−15 4−6 nm with uniform distribution....
Selective elimination of unwanted synapses is vital for the precise formation neuronal circuits during development, but underlying mechanisms remain unclear. Using inositol 1,4,5-trisphosphate receptor type 2 knockout (Itpr2−/−) mice to specifically disturb somatic Ca2+ signaling in astrocytes, we showed that developmental ventral posteromedial nucleus relay synapse was impaired. Interestingly, intracerebroventricular injection ATP, not adenosine, rescued deficit Itpr2−/− mice. Further...
The synthesis of controllable pure and p-type in situ Ta-doped monolayer MoS 2 with different doping concentrations via a one-step salt-assisted chemical vapor deposition (CVD) method systematic characterization studies is reported.
We have developed a composite catalyst featuring acid and base interface that enables the efficient conversion of ethanol to butanol. Our catalyst, which possesses adjacent acid–base sites, exhibits over eightfold increase in dehydrogenation condensation rates per site compared physical mixture base. This demonstrates remarkable synergistic effect these two kinetically relevant steps. Through isotope experiments, we elucidated chemical origin strong activation C–H bond under cooperative...
Tm<sup>3+</sup> can transfer energy to Dy<sup>3+</sup> efficiently, and with increase in MoO<sub>4</sub><sup>2−</sup> content, the chromaticity coordinates changed from edge center of white area.
Based on the land-use data of 2000 and 2015, this study makes a quantitative analysis ecological environment effect in Pearl River Delta using quality index contribution rate change types. The results showed following: (1) During 2000–2015, changes mainly manifested reduction cultivated land, forest water area, unused while area construction land grassland an increasing trend. was largely stable but slightly declined overall; (2) Over past 15 years, comprehensive urban agglomeration has...
Abstract The development of efficient catalyst for selective oxidation hydrocarbon to functional compounds remains a challenge. Herein, mesoporous Co 3 O 4 (mCo ‐350) showed excellent catalytic activity aromatic‐alkanes, especially ethylbenzene with conversion 42 % and selectivity 90 acetophenone at 120 °C. Notably, mCo presented unique path direct aromatic‐alkanes aromatic ketones rather than the conventional stepwise alcohols then ketones. Density theory calculations revealed that oxygen...
Whether the oxygen vacancies of heterogeneous catalysts improve their catalytic activity or not has recently been topic intense debate in oxidation hydrocarbons. We designed an effective strategy to construct mesoporous Ni-Co mixed oxides via a ligand-assisted self-assembly approach. The surface vacancy concentrations oxide were regulated by changing doping amount Ni reduction method, and relationship between was studied. Controlled experiments DFT calculations revealed that molecules more...
Single crystal black phosphorus nanoribbons along the zigzag direction have been successfully grown by chemical vapor transport.
BP grown using lead instead of tin as the mineralizer exhibits better properties, which are beneficial for its applications.
A metal oxide/h-BN/BP structure was built to realize electron doping and air stability for BPFETs.
Gold clusters with ultrasmall size and special structure are highly attractive for heterogeneous catalysis. However, stabilizing gold under thermal treatment remains a major hurdle on the way toward real-world application. Herein, we report an effective approach that (Au25 Au144) within mesoporous ceria nanospheres via two phase overcoating process. High-resolution aberration-corrected STEM studies indicated were encapsulated confined in intersectional channels of ceria, demonstrated to be...
To improve the accuracy of pulse matching and mapping quality lightning discharges, Pearson correlation method combined with empirical mode decomposition (EMD) is introduced for discharge electric field matching. This paper uses new to locate channels an intra-cloud (IC) flash a cloud-to-ground (CG) analyzes location results two flashes. The show that this has good performance in location. Compared pulse-peak feature method, positioning are significantly improved, which mainly due much...
Photodetectors based on two-dimensional materials and their van der Waals (vdW) heterojunctions usually have excellent optoelectronic performance great potential applications.

Subsequently, GaSe nanoflakes exfoliated from grown bulk mechanical exfoliation. The n-Si/p-GaSe...
Greenhouse gases (GHGs) emissions from high-cold terrestrial ecosystems underlain by permafrost on the Qinghai–Tibet Plateau (QTP) have received widespread attention. However, dominant factors regulating ecosystem respiration (Re) and its components (soil Rs heterotrophic Rh) how differences in carbon different ecotypes seasons remain are still unclear. We conducted a 2-year field investigation (August 2018 to October 2020) applied structural equation model (SEM) clarify changes controlling...
