Boron nitride (BN) structures are featured by their excellent thermal and chemical stability unique electronic optical properties. However, the lack of controlled synthesis quality samples electrically insulating property largely prevent realizing full potential BN nanostructures. A comprehensive overview current status two-dimensional hexagonal sheets, three dimensional porous materials BN-involved heterostructures is provided, highlighting advantages different synthetic methods.

Boron, as a unique element nearest to carbon in the periodic table, has been predicted form many distinctive two‐dimensional (2D) structures that significantly differ from other well‐studied 2D materials, owning its exceptional ability strong covalent two‐center‐two‐electron bonds well stable electron‐deficient multi‐center‐two‐electron bonds. Until recently, successful syntheses of atomically thin crystalline boron sheets (i.e., borophenes) provoked growing passion crystals. In this feature...
Bi2 O2 Se is emerging as a photosensitive functional material for optoelectronics, and its photodetection mechanism mostly considered to be photoconductive regime in previous reports. Here, the bolometric effect discovered photodetectors. The coexistence of generally observed multiwavelength photoresponse measurements then confirmed with microscale local heating experiments. unique photodetectors may arise from change hot electrons during temperature rises instead photoexcited holes...
The ferroelectricity in stacked van der Waals multilayers through interlayer sliding holds great promise for ultrathin high-density memory devices, yet mostly subject to weak polarization and cryogenic operating condition. Here, we demonstrate robust room-temperature monolayer graphene sandwiched between hexagonal boron nitride layers with a rhombohedral-like stacking (i.e., ABC-like stacking). system exhibits an unconventional negative capacitance record high electric of 1.76 μC/cm2 among...

In order to explore the pyrolysis mechanism of palm oil as natural ester insulating liquid from molecular aspect, ReaxFF reactive force field was used simulate process oil. Firstly, models four main molecules oil—tripalmitin, trilinolein, triolein, and tristearin—are constructed via density functional theory (DFT). Secondly, vibrational frequencies are calculated, so calculate infrared (IR) spectra. Thirdly, dynamics (MD) simulations employing method performed reaction system under different...
Synthetic two-dimensional (2D) materials without layered bulk allotropes are approaching a new frontier of flatland, one with properties richer than those graphene-like materials. This is the case even as only few chemical elements and blends have shown synthetic 2D forms. While hydrogen metals earth-abundant form numerous compounds, rarely robust metal–hydrogen bonds. Here, large family found from metal hydrides by high-throughput computational search augmented first-principles...
The carbon oxides (CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> and CO) in the insulating oil of power transformers come from thermal aging cellulosic paper; CO /CO ratio can reflect state paper.

We predict by ab initio calculations an $\mathrm{all}\ensuremath{-}s{p}^{2}$ nanostructured carbon phase of a topological hybrid nodal-loop semimetal with momentum-dependent crossings linear bands near the Fermi level. This is assembled from interconnected Riemann surfaces, naturally occurring as screw dislocations in graphitic carbons, which not only result notably higher stability than most previously reported allotropes but also sustain strain-robust nodal loop up to 75% elastic stretch...
Different from hexagonal boron nitride (hBN) sheets, the bandgap of hBN nanoribbons (BNNRs) can be changed by spatial/electrostatic confinement. It is predicted that a transverse electric field narrow and even cause an insulator-metal transition in BNNRs. However, experimentally introducing overhigh across BNNR remains challenging. Here, it theoretically demonstrated water adsorption greatly reduces zigzag-oriented BNNRs (zBNNRs). Ab initio calculations show molecules favorably assembled...

Natural ester insulating oil not only has a biodegradation rate of almost 100% but also meets the carbon emission requirements China's "Carbon Peak and Carbon Neutrality" "European Green Deal" proposed by European Union. It is considered to be good substitute for mineral oil. However, due its higher kinematic viscosity than traditional in low-temperature environments, it limits safety promotion application transformers cold regions. First, we design an experiment test density natural Under...
Here, by utilizing crystal structure analysis through the particle swarm optimization (CALYPSO) structural searching method with density functional theory (DFT), we investigate systemic structures and electronic properties of Ca2Mgn (n = 1-15) clusters. Structural searches found that two Ca atoms prefer to occupy external position magnesium-doped systems at n 2-14. Afterward, one atom begins move from surface into internal caged skeleton 15.

We fabricated 70 nm Al2O3 gated field effect transistors based on two-dimensional (2D) materials and characterized their optical electrical properties. Studies show that the contrast of monolayer graphene an Al2O3/Si substrate is superior to a traditional 300 SiO2/Si (2.4 times). Significantly, transconductance shows approximately 10-fold increase, due smaller dielectric thickness higher constant. Furthermore, this also suitable for other 2D materials, such as WS2, can enhance remarkably by...
