Essentially all research done to date on the mechanical properties of polymeric semiconductors (e.g., for organic photovoltaics and thin-film transistors) has had underlying goal increasing "stretchability": that is, deformability softness. However, softness is wrong characteristic many applications envisioned semiconductors, including touch screens, chemical sensors, distributed sources solar energy at risk damage by indentation, scratching, abrasion. A focus modulus ultimate...
The conductive polyelectrolyte complex poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is ubiquitous in research dealing with organic electronic devices (e.g., solar cells, wearable and implantable sensors, electrochemical transistors). In many bioelectronic applications, the applicability of commercially available formulations PEDOT:PSS Clevios) limited by its poor mechanical properties. Additives can be used to increase compliance but pose a risk leaching, which result...
The mechanical properties of π-conjugated (semiconducting) polymers are a key determinant the stability and manufacturability devices envisioned for applications in energy healthcare. These properties─including modulus, extensibility, toughness, strength─are influenced by morphology solid film, which depends on method processing. To date, majority work done semiconducting has been performed films deposited spin coating, process not amenable to manufacturing large-area films. Here, we compare...
Conjugation-break spacers (CBS) have been shown to enhance the mechanical properties of conjugated polymers. In particular, incorporation CBS units into semi-random polymers has revealed high ductility and low elastic moduli, attributed combined influence architecture. To further elucidate structure–property relationships in these polymers, two new families are reported here. first, poly(3-hexylthiophene)-based incorporating diketopyrrolopyrrole (DPP) were synthesized which with 4–10 carbons...
Abstract Crosslinking is a ubiquitous strategy in polymer engineering to increase the thermomechanical robustness of solid polymers but has been relatively unexplored context π‐conjugated (semiconducting) polymers. Notwithstanding, mechanical stability key many envisioned applications organic electronic devices. For example, wide‐scale distribution photovoltaic devices incorporating conjugated may depend on integration with substrates subject insult—for road surfaces, flooring tiles, and...
This paper demonstrates that a thin polymeric film (10–80 nm) can be continuously drawn from the meniscus of nonpolar polymer solution at an air–water–fluoropolymer interface using roll-to-roll process: "interfacial drawing". With this process, it is possible to control thickness by manipulating concentration solution, along with drawing velocity receiving substrate. We demonstrate formation films >1 m in length and 1000 cm2 area, our custom-designed apparatus. Interfacial has three...
The functionality and usability of π-conjugated (semiconducting) polymers is dependent on the adhesive interfacial properties solid film. Such are critical in devices incorporating semiconducting because these layers serve both an active structural role. They load bearing sense that bending, stretching, scratching, impact places stress within film at interfaces with other device stack. Thus, organic semiconductors must have good cohesive despite being designed primarily for optoelectronic...
Agenesis of maxillary lateral incisors and mandibular second premolars is the most frequent form hypodontia. Its prevalence varies across population from 0.8% to 4.5%. Genetic aberrations environmental factors may cause agenesis one or more teeth. The management child having such a problem very important since diastema in teeth especially upper anteriors not only affects child's physical appearance but also its psychological development as wants look like other children. In this article...
Background: Chemomechanical caries removal (CMCR) is a noninvasive procedure that uses chemical substance to remove the diseased dentin. The natural dental architecture also preserved using this technique, preventing patient discomfort and pulp irritation. This method of eliminating based on disintegration. removes soft carious dentin agents non-traumatic mechanical force. study was carried out evaluate clinical microbiological evaluation chemomechanical in primary molars. Methods: For...
Background: Bruxism in paediatric dentistry refers to the habitual grinding or clenching of teeth children. This condition can manifest during day night and may have various underlying causes. has multifactorial etiology including disturbed sleep cycle excessive gadget use Present study aimed evaluate knowledge awareness parents about bruxism children who visited department. is a common concern dentistry, presenting challenges for dental professionals alike managing addressing its effects on...
Background: Dental anxiety among children can significantly impact their overall oral health and well-being. This study aims to assess the levels of dental age 7 12 in a clinic waiting room using Modified Anxiety Scale (MDAS). The this observational were evaluate previous visits on aged who for treatment. Materials & Methodology: A total 234 years included study, assessed MDAS. scale, comprising questionnaire five items related anxiety, was administered each participant room. Result :...
With an objective to better understand differences in oral health related behavior and practices of working non working, this study was conducted. Duration the three months, from August 2021 October it conducted Department Periodontics, Mansovar Dental College Research Center, Bhopal (M.P.), India. A questionnaire based survey amongst 300 married female participants aged 18 years or more (111 women 189 non-working women). The samples were heterogeneous group different occupation economic...
