The prepared textured surface is tested for the shape of V-groove channel, wetting behavior, and tribological aspect. A decrease in shape error of V-groove channel is observed as the peak current increases from 4 A to 10 A due to an increase in discharge energy which functions as the melting or vaporizing of machined materials. The water contact angle decreases from 61.3160 (untextured surface) to 49.5670 (sample 4) showing an increase in hydrophilic behavior for the samples having nearly a V-groove-shaped channel. Further, there is a decrease in COF value from 0.48 (untextured surface) to 0.23 (sample 4). The decreased COF value attributes to the formation of metallic bridges in the V-groove channel.

Originally made using materials like gold, silver, iron, and wood, catheters have evolved into advanced designs over the centuries across the world. Benjamin Franklin’s 1752 invention of a silver catheter made of hinged segments of tubes may be considered the first flexible catheter in recorded history [Figure 1]. The modern balloon-based self-retaining catheter, introduced in 1933, marked a turning point in catheter design and development. Today, three main types of catheters are used: indwelling, external, and short-term catheters, which are available in various sizes, materials (including latex, silicone, Teflon, PVC, etc.), and types (straight or coude tip). The invasive nature of catheters comes with risks of microbial growth and incompatibility with the human system, leading to infection, inflammation and device rejection and the need to change them frequently especially in the elderly. Catheter-associated urinary infections (CAUTIs) pose a significant concern, contributing to increased mortality rates and substantial economic burdens. UTIs account for 20 to 40% of hospital-associated infections, with an estimated 80% linked to urinary catheters [3]. There has been increasing interest in developing surface modification techniques to afford microbicidal properties and biocompatibility to catheter surfaces, as seen in the increasing number of publications in the area [Figure 2]. These surface modification methods involve the use of coatings or physical microand nano-dimensional surface modifications [4]. Coatings can be classified based on their mechanism of action: passive strategies include antifouling surfaces, while active approaches involve antimicrobial coatings that disrupt biological pathways. Antifouling coatings, especially hydrogels [5], poly (tetrafluoroethylene) [6], polyzwitterions [7], and poly (ethylene glycol) [8] are being explored. These coatings are often loaded with antimicrobial agents such as antibiotics, biocidal enzymes, and bacteriophages [9]. The agents prevent CAUTIs through mechanisms such as the slow release of microbicidal chemicals, modifying catheter surfaces to prevent microbial adherence, and disrupting biofilms that allow pathogen colonization. For example, researchers developed a poly(sulfobetaine methacrylate)-tannic acid hydrogel coating loaded with antimicrobials (poly(vinylpyrrolidone)-iodine, copper ions, and nitrofurazone) through non-covalent interactions. The coating exhibited pH-responsive release of the antibacterial agents under alkaline conditions, offering improved antibacterial activity against urease-producing bacteria [10]. Urinary catheters have been coated with thin layers of silver in the form of silver oxide or silver alloy, as well as noble metal alloys (gold, silver, and palladium), to reduce bacterial adherence to their s","PeriodicalId":21995,"journal":{"name":"Surface Engineering","volume":"39 1","pages":"515 - 520"},"PeriodicalIF":2.8,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42912370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the findings, the Mg/2.5%HA and coated Mg/2.5%HA samples can withstand more than 1 million cycles under 60 MPa. Compared to pure Mg, Mg/2.5%HA has better corrosion and corrosion fatigue resistance. Furthermore, a PCL/2.5%HA fibre coating can increase the corrosion fatigue resistance of Mg/2.5%HA as a result of the polymer scaffold, passive protective layer, and apatite adsorption capability.

In pure TEOS pretreatment, microcracks, and much gel-like materials were observed on the zeolite coating. The electrochemical test revealed that the zeolite coating on a 50/50 mixture of the APTES/TEOS pretreated substrate exhibited the highest corrosion resistance in 3.5 wt-% NaCl solution.

It is noticed the COFs of smooth surface, SPTS and RPTS are all greater than 0.6 after the test, while the GTS has the lowest COF, which remains around 0.2 throughout the test. The vibration signals detected from all surfaces indicate the larger COF will not trigger the FIV generation in this state. All the texture surfaces will not cause electrical contact breaks. Worn surface analysis indicates the wear level of GTS is the weakest, with slight damage and debris accumulation occurs along the groove edges.

While these conditions primarily develop as a result of aging, they can also be caused by congenital abnormalities, specific diseases, or physiological processes such as rheumatic heart disease and pregnancy. Surgical replacement of the faulty valve with prosthetic valves remains the preferred and most effective treatment for all types of VHD. In 2020, over 180,000 heart valve replacements were performed in the US alone [1]. Charles Hufnagel is considered the pioneer in the design of prosthetic heart valves. The first Hufnagel heart valve was implanted in 1952 using a Lucite tube and methacrylate ball in the descending aorta. Over the past century, significant advancements have been made in the development of prosthetic heart valves, and continuing research is dedicated to engineering optimal designs. [2] (Figure 1). The prosthetic heart valve comprises three components: the valve ring, the valve leaf, and the sewing ring (Figure 2). The valve ring and leaf are typically made of titanium, 316L stainless steel (SS) or cobaltchromium (Co-Cr) alloys, low-temperature isotropic pyrolytic carbon, or expanded polytetrafluoroethylene (ePTFE) or polyethylene terephthalate (PET) [3]. While progressive designs of prosthetic heart valves have improved haemodynamic properties, the introduction of a foreign object into the human body comes with its own set of complications [5]. The common problems include thrombosis, haemorrhage related to anticoagulant use, infections, valve failure, tissue hyperplasia, and overgrowth. Thrombogenicity or clot formation on the surfaces of the internal prosthesis is triggered by the adhesion and activation of platelets on them. This in turn is guided by the protein layer, especially human plasma fibrinogen (HPF). Inflammatory reactions such as restenosis and calcification are also caused by the release of toxic ions from the metals or alloys and the degradation of polymeric components of the artificial valves. A promising strategy to limit thrombogenicity is to modulate HPF behaviour at the blood-material interface by altering the physicochemical properties of the valve’s (or any prosthetic device’s) surface. Surface modifications aim to optimize various aspects of blood-material interactions, including protein adsorption, thrombin generation and blood coagulation, platelet adhesion, aggregation and activation, and cellular behaviour at the prosthesis surface [6]. A recent study showed the relationship between surface crystallographic structure and platelet adhesion. Valve rings are often made of titanium or pyrolytic carbon, the surface of which is often engineered to have a layer of titanium oxide [7]. The rutile crystallographic structure typically has three lowindex (110), (100), and (101) facets","PeriodicalId":21995,"journal":{"name":"Surface Engineering","volume":"39 1","pages":"387 - 391"},"PeriodicalIF":2.8,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48229421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
