Donor-acceptor type light-harvesting molecular wires are covalently attached to a borondoped diamond surface via a combination of diazonium electrografting and Suzuki crosscoupling. For the Suzuki reaction, various catalytic systems are compared with respect to their imposed surface coverage. Combining 2-dicyclohexylphosphino-2’,6’-dimethoxybiphenyl (SPhos) and Pd(0), the diamond coverage impro...

Penile strangulation is a rarely described medical emergency, especially in the adolescent population. This case demonstrates the successful removal of a constricting metal ring from the penis of a 14-year-old male with a diamond blade equipped orthopedic oscillating saw while under ketamine anesthesia in the emergency department.

Diamond wire sawing is one of the most widely used methods cutting Al2O3 ceramic because it has good machining accuracy and causes less surface damage. However, its material removal rate (MRR) needs to be improved with increasing demand for parts. In this paper, spark discharges are generated around diamond based on electrochemical discharge (ECDM) process. An oil film-assisted ECDM process app...

We have used 3-D coupled field structural finite element models to study the acoustic wave propagation characteristics of diamond/AlN/LiNbO3 multilayered piezoelectric surface acoustic wave devices for applications in chemical and biological sensing. These devices were studied as a method to increase device frequency and sensitivity, and maintain standard fabrication procedures. Although recent...

In this study, amino group surface-functionalized porous silicon adsorbent was successfully prepared for the first time using diamond wire saw powder (DWSSP) as raw material through copper-assisted chemical etching (Cu-ACE) and organic functional grafting. Amino-functionalized (TEPA-GTS-NPSi) can be used removing As(V) from water. The properties mechanism of new were characterized by infrared s...

Unconstrained metal powders of chromium and nickel, in combination with aluminium, were used the submerged arc welding (SAW) process to simplify weld alloying. refer non-alloyed that are not constrained tubular wire, such as fluxed-cored metal-cored wire. Aluminium powder is control oxygen potential at molten flux–weld pool interface. The results presented here show addition aluminium enhances ...

A series of sawing experiments on granite was carried out to explore the cutting performance a diamond frame saw with horizontal reciprocating mode. model average thickness chip established and characteristics forces were analyzed. The wear mechanism segments revealed by analyzing width kerf morphology segments. results demonstrated that resistance increased feed speed. changed abruptly at reve...
