“…Lanthanide-doped nanomaterials enable the conversion from near-infrared light to visible light due to the anti-Stokes effect when two or more low-energy photons are sequentially absorbed and higher-energy photons are emitted [ 1 , 2 , 3 , 4 ]. These nanomaterials have the advantages of long luminescence lifetimes, narrow emission bands, high penetration abilities and chemical stability, making them suitable for potential applications in bioimaging, infrared photothermal therapy, fluorescent biomarkers, anti-counterfeiting, photocatalysis, photodetectors, optoelectronic devices, sensors and other fields [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. In particular, red-upconversion-luminescence nanomaterials can be better suited to biological applications.…”

Na3ScF6: 20% Yb3+, 2% Er3+ samples were synthesized with different reaction times and reaction temperatures using the solvothermal method. We carried out a series of tests on Na3ScF6 crystals. The XRD patterns showed that the monoclinic phases of the Na3ScF6 samples could be synthesized under different reaction conditions, and doping with Yb3+ ions and Er3+ ions did not change the crystal structures. The SEM images showed that the sizes of the samples gradually increased with reaction time and reaction temperature. The fluorescence spectra showed that the emission peaks of the prepared samples under 980 nm near-infrared (NIR) excitation were centered at 520 nm/543 nm and 654 nm, corresponding to the 2H11/2/4S3/2→4I15/2 and 4F9/2→4I15/2 transitions, respectively. With the increasing size of the samples, the emission intensities at 654 nm increased and the luminescence colors changed from green to red; at the same time, the red-to-green luminescence intensity ratios (IR/IG ratios) increased from 0.435 to 15.106—by as much as ~34.7 times. Therefore, this paper provides a scheme for tuning the IR/IG ratios of Na3ScF6: 20% Yb3+, 2% Er3+ samples by changing their sizes, making it possible to enhance the intensity of red upconversion, which has great potential for the study of color displays and lighting.

“…Apart from cast and laser clad-ding methods for preparing HEAs, numerous researchers have employed other manufacturing methods, such as laser melting deposition [23], powder plasma arc additive manufacturing [24], cable wire arc additive manufacturing [25], and thermomechanical processing [26], to create Al-Co-Cr-Fe-Ni system HEAs and similar techniques, achieving desirable mechanical properties. In addition to metallic elements such as Cr, Ti, Mo, and Al, non-metallic elements also play a vital role in the microstructure and properties of HEAs, according to metal-lurgy theory [27][28][29][30]. Chen Guojin et al [31]found that adding B element to FeCoCrNi HEA promotes the precipitation of the M3B phase (M=Fe, Cr), thereby improving the hardness and wear resistance of the high entropy alloy coatings.…”

The Al0.8CrFeCoNiCu0.5Si0.5 high-entropy alloy was synthesized using the vacuum arc melting method, and its microstructure and properties were analyzed. The equilibrium solidification phase diagram of the alloy was calculated using Thermo-Calc software. The alloy consisted of BCC1, BCC2, and Cr3Si phases, consistent with the calculation results of the phase diagram. The microstructure of the alloy was dendritic, with secondary dendritic arms. The interdendritic structure was rich in the Al-Ni phase, and the dendritic structure was rich in the Fe-Cr-Si phase. The distribution of Co and Cu was relatively uniform. The cooling condition of the alloy was found to be an essential factor affecting the formation of the Cr3Si phase, according to the phase diagram calculation results and solid-state nucleation theory. The hardness of the alloy was measured to be 578 HV0.2, and the wear rate was 3.27×10-7mm3/Nm. The wear mechanism was abrasive wear. The analysis of the microstructure and properties of the Al0.8CrFeCoNiCu0.5Si0.5 high-entropy alloy suggests that it has potential applications in industries that require high hardness and resistance to wear.

“…As another modification method of the solid surface, anti-scale coating can reduce the adhesion strength between the scale and heat transfer interface, reducing the deposition of scale. The coating can also effectively isolate the plate from the outside world and prevent external damage to the base material [11,12].…”

Some surface coatings can protect metal surfaces and reduce scale deposition. Based on that, the biomimetic material polydopamine (PDA) can form a stable coating on many material surfaces; therefore, we propose an efficient one-step electroplating method for preparing anti-scale PDA coatings with high stability. The scale deposition test showed that the deposition weight of calcium carbonate on the coating is less than that of carbon steel after immersing in a supersaturated solution of calcium carbonate for 12 h at 70 °C and 90 °C, with a coating scale-inhibition efficiency of 55.02% and 66.96%, respectively. By using molecular dynamics simulation, it was found that water adsorption layers exist near the metal’s surface, and the existence of water adsorption layers on the hydrophilic surface is the main reason for the initial deposition of calcium carbonate. The interaction energy between the PDA molecular layer and water is weaker (−5.69 eV) for the surface with the PDA coating, and there is no dense water adsorption layer on the coating, which leads to the low probability of calcium carbonate adsorption on the PDA coating surface. Therefore, PDA coating can inhibit the deposition of calcium carbonate on the surface.
