Abstract Hard tissue repair and regeneration cost hundreds of billions dollars annually worldwide, the need has substantially increased as population aged. tissues include bone tooth structures that contain calcium phosphate minerals. Smart biomaterial-based engineering regenerative medicine methods have exciting potential to meet this urgent need. biomaterials constructs refer possess instructive/inductive or triggering/stimulating effects on cells by material’s responsiveness internal...
The purpose of this study was to fabricate a low-immunogenicity fish collagen (FC) and bioactive nanohydroxyapatite (n-HA) enhanced poly(lactide-co-glycolide) (PLGA) nanofibrous membrane for guided bone regeneration (GBR) via electrospinning. physicochemical properties morphology revealed that FC n-HA particles were homogeneously dispersed in the PLGA fibrous matrix. Notably, formation polymeric chain network due interaction between significantly improved tensile strength membrane....
Dental restorative materials with antimicrobial properties can inhibit bacterial colonization, which may result in a reduction of caries at tooth-filling interaction zones. This study aimed to develop antibacterial glass–ionomer cements (GIC) containing quaternary ammonium monomer (dimethylaminododecyl methacrylate, DMADDM), and investigate their effect on material performance properties. Different mass fractions (0, 1.1% 2.2%) DMADDM were incorporated into the GIC. The flexure strength,...
Resin composites and adhesives are increasingly popular in dental restorations, but secondary caries is one of the main reasons for restoration failure. Quaternary ammonium monomers (QAMs) have an anti-microbial effect widely used many fields. Since concept immobilized antibacterial was put forward, restorations containing QAMs been studied to reduce caries. Previous studies struggling develop novel anti-caries materials which might triple benefits: good mechanical properties, effects...
The objectives of this study were to investigate the effects dental adhesives containing quaternary ammonium methacrylates (QAMs) with different alkyl chain lengths (CL) on ecological caries prevention in vitro. Five QAMs synthesized a CL = 3, 6, 9, 12, and 16 incorporated into adhesives. Micro-tensile bond strength surface charge density used measure physical properties proportion change three-species biofilms consisting Streptococcus mutans, sanguinis, gordonii was tested using TaqMan...
The mechanical properties and anti-caries effect of a novel adhesive containing poly (amidoamine) dendrimer (PAMAM) dimethylaminododecyl methacrylate (DMADDM) were investigated for the first time. Microtensile bond strength surface charge density measured adhesives. Streptococcus mutans, sanguinis, gordonii chosen to form three-species biofilms. Lactic acid assay, MTT (3-(4,5-Dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide) exopolysaccharide staining live/dead performed study...
The prevalence of stomatitis, especially caused by Candida albicans, has highlighted the need new antifungal denture materials. This study aimed to develop an heat-curing resin containing quaternary ammonium monomer (dimethylaminododecyl methacrylate, DMADDM), and evaluate its physical performance properties. discs were prepared incorporating DMADDM into polymer liquid a methyl methacrylate-based, heat-polymerizing at 0% (control), 5%, 10%, 20% (w/w). Flexure strength, bond quality, surface...
Field experiments were conducted to study the effects of controlled release urea (CRU) application on growth yield and nitrogen recovery efficiency cotton in main zone Yangtze River basin 2010. Different levels set order determine suitable dosage CRU cotton. The special purpose was provide evidence for fields. results show that promotes significantly enhances supply whole period. Compared treatment with total N as base fertilizer (UB), bod, flower, little bolls are increased significantly....
In this paper, we investigate the existence of a uniform attractor for non-autonomous suspension bridge equation with time delay by using energy function and asymptotic compactness process.
We investigate the long-time behavior of solutions for suspension bridge equation when forcing term containing some hereditary characteristic. Existence pullback attractor is shown by using contractive function methods.
Due to the short dwell time of processing temperature and pressure, quality composite manufactured by AFP was not equal traditional method like autoclave or hot-press. Deeply understanding mechanism differences conducive improving performance AFP. In this study, properties high-performance carbon fiber reinforced polyphenylene sulfide (CF/PPS) thermoplastic composites laser-assisted automated placement (LAFP) in-situ consolidation hot-press characterized compared. The history LAFP in situ...
In recent years, with the rapid development of economy and improvement people's material living standards, e-commerce is booming, Courier service industry arises at right moment.In order to solve problem delivery in remote areas, three key factors affecting unmanned aerial vehicles (UAVs) were considered, coverage model UAVs was established realize full points target area.Secondly, UAV distribution non-repeated cross-distribution each achieve lowest cost highest efficiency...
With the introduction of immersion lithography into IC manufacturing for 45nm node, pattern collapse and line width roughness (LWR) remain critical challenges that can be addressed by implementing formulated surface conditioners. Surface conditioners are capable solving multiple issues simultaneously easily integrated post-develop photolithography process.

Demand for Immersion topcoat-less resist processes is being driven by the desire to reduce cost per wafer pass. Two key characteristics, required high speed immersion scanners, of are receding contact angle and low leaching rates. The extremely hydrophobic surface scanner provides significant challenges remaining processing steps, especially (developer) process related defects: pattern collapse residuals. Recent developments in materials techniques have led very promising results. In this...
In this paper, we consider the suspension bridge equation with variable delay. The long‐time dynamics of solutions for equations without delay effects have been investigated by many authors. But there are few works on Moreover not studies attractors other systems Thus, study existence pullback attractor using theory multivalued dynamical systems.
