“…The extra peak observed at 287.4 eV for hybrid 4 is attributed to the CO carbon of the aldehydic group of the ASCs. 37,38 The deconvoluted XPS spectra of Mo showed peaks at 236.0, 234.9, 232.9, and 231.9 eV for hybrid 1 ; 236.0, 235.0, 232.9 and 231.7 eV for hybrid 2 ; 235.8, 234.7, 232.6, and 231.7 eV for hybrid 3 and 235.7, 234.7, 232.6 and 231.6 eV for hybrid 4 . These four peaks observed for each hybrid are attributed to the four different states of Mo, i.e.…”

“…All the spectra can be deconvoluted into four peaks. The first group of peak contributions, located in the range of 282.9–283.3 eV, is characteristic of metal carbides [ 30 , 31 ]. The second group of contributions at 284.4–284.9 eV could be associated with C-C bonds [ 32 ].…”

Hexagonal boron-nitride nanoparticle coating was deposited on AISI 1045 steel surface. The deposition process included a transformation of B-containing thin organic film into nanocrystalline BN using two methods: thermal annealing at 450–850 °C and reactive ion etching in Ar/N2 plasma. The film structure, phases, and film morphology of deposited nanoparticles of boron nitride on AISI 1045 steel were characterized by XPS, XRD, and EDS. Post-annealing at 450 °C does not lead to the formation of a BN phase in the layer. A non-stoichiometric BN phase with nitrogen deficiency appears at 650 °C. At 850 °C annealing, the formed BN phase is completely stoichiometric. The effects of deposited and incorporated BN on the friction and hardness properties of AISI 1045 steel were also studied. The post-annealing process improved the hardness from 5.35 to 11.4 GPa, showing a pronounced linear temperature dependence. An original approach was adopted to quantify the energy-dependent growth constants based on the indentation load-discharge curves measured on samples treated under different conditions. Those constants describe the rate of the reactions and the type of interdiffusion process characteristic for each material used. This approach can partially fulfill the role of the Rutherford backscattering spectrometry profile, which is an expensive and time-consuming process, mainly when light elements such as boron and nitrogen are used.

“…Such stress was further alleviated by manipulating the distribution of both diamond and β-SiC phases in the interlayer, which were grown using either MPCVD ,,− or HFCVD ,, techniques. To deposit gradient composite interlayers, the TMS flow rate was gradually reduced.…”

“…The advantage of this approach was the simultaneous growth of both a diamond top layer and a gradient composite interlayer within a single process. Since residual stress was gradually released in the gradient layer, the top diamond layer was nearly stress-free whatever on a Si substrate or metal substrates. , The reduced residual stress thus improved the adhesion of a diamond film on the related substrates (Figure ). Such a statement was further confirmed with the Brinell indentation tests .…”

Metrics & MoreArticle Recommendations CONSPECTUS: Diamond composite (DC) refers to a system which consists of diamond (Dia) and other components. Various interactions between diamond and other components exist. The first DC, Dia/β-silicon carbide (β-SiC) composite, was grown in 1992 by means of chemical vapor deposition (CVD) technique. Later on, precise control of the distribution, crystallinity, and orientation of both diamond and β-SiC phases in these composites was sequentially achieved, generating numerous Dia/β-SiC composites and further leading to their wide applications in diverse fields. Inspired by the activities of Dia/ β-SiC composites, other DCs, produced using different CVD techniques, have been reported, including Dia/carbides, Dia/oxides, Dia/nitrides, Dia/sp 2 -carbon, Dia/metal, Dia/metal alloy, and Dia/organic composites. Meanwhile, these composites possess different micro-and nanostructures. Since DCs fully combine the outstanding properties of diamond with those of other components, their utilization in the mechanical, physical, chemical, and biomedical fields have been extensively explored and tested. This "1 + 1 > 2" strategy is believed to be extremely efficient and useful to design and explore advanced diamond functional materials. The origin of superior enhancement and/or new properties of these DCs using the "1 + 1 > 2" strategy stems from the interface and interactions between individual components as well as their synergistic effects. This Account summarizes the progress and achievements of DCs in our group. Their typical synthesis methods, namely, dry and wet ones, are first overviewed. The dry methods are conducted in the gas phase(s), covering high-pressure high-temperature (HPHT) method, CVD method, and physical vapor deposition (PVD). While the wet methods mainly include electrochemical deposition and hydrothermal processes. The mechanical, and physical features of different Dia/β-SiC DCs are then detailed. Some application examples of these Dia/β-SiC DCs are highlighted. In the second part of this Account, synthesis and applications of other DCs, especially those with photo/electrochemical features, are illustrated, for example, the electrocatalysis of Dia/graphite composites toward oxygen reduction/evolution reactions (ORR/OER) and further the construction of flexible zinc-air batteries, the use of Dia/ oxides (carbide) composites for the construction of battery-like supercapacitors, the employment of Dia/TiO 2 composites for photoelectrochemical degradation of environmental pollutants, and the application of Dia/metal composites for electrochemical sensing. This Account finishes with the future prospects of DCs, encompassing their meticulous conceptualization and synthesis, as well as their multifarious applications across diverse domains.
