“…The author recognized that the use of DLC deposited tools reduces feeding forces when Al-Si alloys are turned. Few researchers explored the performance of DLC coated cutting tools on different workpiece materials under various cutting operations and and it was observed a much reduced process of adhesion for the DLC layer over the substrates [3][4][5][6][7][8][9]. These authors found that during machining of aluminium alloys, Experimental assessment on machinability performance of CNT and DLC coated HSS tools for hard turning DLC films allows to avoid the adherence of aluminium on the tool surface, reduce cutting forces, increase the surface roughness and accuracy of the machined surface, facilitate the evacuation of chips and reduce the wear significantly.…”

Enantiomeric excess and purity play pivotal roles across various fields, foremost among them the pharmaceutical industry. Chiral resolution is a crucial technique, enabling the analysis of enantiomeric excess and the procurement of purified enantiomers. Despite their widespread utilization, chiral materials still encounter numerous challenges. Recently, covalent organic frameworks (COFs), as emerging porous organic materials, stand out as promising platforms for various applications due to their high porosity, ordered crystallinity, and exceptional thermal and chemical stability. In particular, the chiral COFs (CCOFs) have emerged as promising candidates for racemate resolution. However, systematic reviews on chiral resolution utilizing CCOFs are scant, likely due to their nascent application. This review delves into the synthesis of CCOFs, summarizing three primary methods: direct synthesis, postsynthesis, and chiral induction. Additionally, it offers an insightful exploration of CCOFs' applications in racemate resolution. Lastly, this review highlights the current challenges and future prospects for their further development and utilization.

“…Most of the past studies aimed to achieve a specific property of amorphous carbon coatings, such as high hardness [9,10]. A few reports discussed the growth of a-C:H coatings that had combined high transmittance and mechanical strength (e.g., Young's modulus and hardness) [11][12][13][14][15][16][17]. Producing highly transparent a-C:H with high density and hardness is a challenge to conventional PECVD [9,[17][18][19].…”

A single beam plasma source was used to deposit hydrogenated amorphous carbon (a-C:H) coatings at room temperature. Using methane source gas, a-C:H coatings were deposited at different radio frequency (RF) power to fabricate transparent and durable coatings. The film deposition rate was almost linearly proportional to the ion source power. Hydrogenated amorphous carbon films of ~100 nm thickness appeared to be highly transparent from UV to the infrared range with a transmittance of ~90% and optical bandgap of ~3.7 eV. The coatings also possess desirable mechanical properties with Young’s modulus of ~78 GPa and density of ~1.9 g/cm3. The combined material properties of high transmittance and high durability make the ion-source-deposited a-C:H coatings attractive for many applications.
