Abstract Due to substantial phonon scattering induced by various structural defects, the in‐plane thermal conductivity ( K ) of graphene films (GFs) is still inferior commercial pyrolytic graphite sheet (PGS). Here, problem solved engineering structures GFs in aspects grain size, film alignment, and thickness, interlayer binding energy. The maximum reaches 3200 W m −1 outperforms PGS 60%. superior strongly related its large intact grains, which are over four times larger than best PGS....

Traditional white light-emitting diodes (w-LEDs) have a cyan gap between 480 and 520 nm, which leads to the reduction of color vividness. Herein, new combination strategy is proposed prepare full-spectrum w-LEDs: blue phosphors broad orange-yellow originated from Cs2NaInCl6 are blended on an ultraviolet (UV) chip. We obtained broadband by introducing Sb3+ Ag+/Bi3+, respectively, into Cs2NaInCl6. Cs2NaIn0.97Cl6:0.03Sb3+ Cs2Na0.9Ag0.1In1–yCl6:yBi3+ (y = 0.03, 0.1, 0.2, 0.6, 1) were employed...
Layered hybrid perovskites show significant advantages in the field of optoelectronics. However, low quantum efficiency and complex preparation methods limit their applications. In this work, we developed a series perovskite powders with two-dimensional (2D) layered structure organic–inorganic metal halides M2CdCl4:x%Mn (M = CH3NH3+, C2H8N+, C3H10N+) via facile mechanochemical methods. The prepared manganese Mn-doped MA2CdCl4 produces orange emission at 605 nm under both 254 420 excitation,...

According simulation of slice design, received different dose pairs (0 1.1 μg/kg) sufentanil (.1 .5 μg/kg). The mean arterial blood pressure heart rate recorded just before...
Room-temperature ferromagnetism was observed in Ge nanostructures deposited on polystyrene nanospheres. Various layers (3, 5, 10, and 20nm) were different nanospheres (20, 30, 50, 100nm diameter). The magnetization influenced by both the thickness of size Maximum (360emu∕g) magnetic moment (4.7μB∕Ge) sample with a 5nm thick layer diameter 20nm. attributed to quantum effect junctions among nanostructures.
Base metal nickel is often used as the inner electrode in multilayer chip positive temperature coefficient resistance (PTCR). The fine grain of ceramic powders and base are necessary.
