“…Quartz glass may be an immaculate shape of silica with a SiO 2 content of more than 99.9% and it has been used widely in lenses, computers, resonators, windows, smartphones, GPS equipment, communication (3C) engineering, and electronic industries for high-quality tuned circuits. Quartz is widely used in micro device testing, metrology components, jewelry, gemstones, frequency control, mirror substrates, piezoelectric applications for converting electrical to mechanical energy (and vice versa), and medical incision devices [ 6 , 7 , 8 , 9 ]. Owing to its higher hardness, brittleness, and higher melting point, machining quartz is difficult [ 10 ] and thus quartz was used as the workpiece material for the study.…”

Many microslits are typically manufactured on quartz substrates and are used to improve their industrial performance. The fabrication of microslits on quartz is difficult and expensive to achieve using recent traditional machining processes due to its hardness, electrically insulating nature, and brittleness. The key objective of the current study was to demonstrate the fabrication of microslits on quartz material through a magnetohydrodynamics (MHD)-assisted traveling wire-electrochemical discharge micromachining process. Hydrogen gas bubbles were concentrated around the entire wire surface during electrolysis. This led to a less active dynamic region of the wire electrode, which decreased the adequacy of the electrolysis process and the machining effectiveness. The test results affirmed that the MHD convection approach evacuated the gas bubbles more rapidly and improved the void fraction in the gas bubble scattering layer. Furthermore, the improvements in the material removal rate and length of the cut were 85.28% and 48.86%, respectively, and the surface roughness was reduced by 30.39% using the MHD approach. A crossover methodology with a Taguchi design and ANOVA was utilized to study the machining performance. This exploratory investigation gives an unused strategy that shows a few advantages over the traditional TW-ECDM process.

“…Bone defects are replaced with resorbable ceramics or carbon materials, whereas cosmetic implants are made of silicone ensuring mechanical properties comparable to those of natural soft tissue. [18][19][20][21] At present, commonly found and applied implant systems utilize solutions manufactured by means of the 3D printing technology (3DPT). [22,23] This technology is developing intensively, enabling the production of very small and precise components of complex shapes and very high accuracy.…”

There are many known bone stabilization systems. New implant systems are finding to fixation of bone multifractures. One of such stabilization system is analyzed in this article. This article is focused on the material research of the elements of the innovative system designed to fixation of multisite bone fractures. The components are manufactured by means of the selective laser melting (SLM) 3D printing technology (3DPT). Their chemical composition, as well as the surface and internal structure of small‐sized elements, is tested. The influence of heat treatment on the internal structure and, consequently, strength is investigated. Herein, novel bone fracture fixation implants made of titanium alloy (Ti–6Al–4V) manufactured through SLM 3DPT are investigated. The microstructures of the main components of the new modular implant fixation system are assessed, as well as hardness distribution and morphology of the fractures induced in tension and bending. It is found that the implant elements assessed are free from harmful chemicals, and the structures obtained exhibit high strength and present a porous surface that is suitable for osseointegration promotion. In summary, the fabricated titanium implants are expected to be adequate for the treatment of bone fractures.

“…Therefore, alternative methods in the form of different types of stents should be increasingly used. In the urinary system, stents, which are usually made of metal, polymer, or hybrid materials in which the metal is covered with a polymer layer [ 21 , 22 , 23 , 24 , 25 , 26 , 27 ], are used. It should be noted that the use of this type of irritant is not always correct.…”

Background: Frequency of urethral stenosis makes it necessary to develop new innovative methods of treating this disease. This pathology most often occurs in men and manifests itself in painful urination, reduced urine flow, or total urinary retention. This is a condition that requires immediate medical intervention. Methods: Experimental tests were carried out on a rabbit in order to determine the changes of pressure in the urethra system and to estimate the velocity of urine flow. For this purpose, a measuring system was proposed to measure the pressure of a fluid-filled urethra. A fluoroscope was used to observe the deformability of the bladder and urethra canal. Results: Based on these tests, the range of changes in the urethra tube diameter, the pressures inside the system, and the flow velocity during micturition were determined. Conclusions: The presented studies allowed determining the behavior of the urethra under the conditions of urinary filling. The fluid-filled bladder and urethra increased their dimensions significantly. Such large changes require that the stents used for the treatment of urethral stenosis should not have a fixed diameter but should adapt to changing urethral dimensions.
