Abstract Recently, graphene-based nanomaterials, in the form of two dimensional substrates or three foams, have attracted considerable attention as bioactive scaffolds to promote differentiation various stem cells towards specific lineages. On other hand, potential advantages using hybrid composites directly factors inducing cellular well tissue regeneration are unclear. This study examined whether nanocomposites reduced graphene oxide (rGO) and hydroxyapatite (HAp) (rGO/HAp NCs) could...
A high-yield solution-processed ultrathin (<10 nm) trigonal tellurium (t-Te) nanowire (NW) is introduced as a new class of piezoelectric nanomaterial with six-fold higher constant compared to conventional ZnO NWs for high-volume power-density nanogenerator (NG). While determining the energy-harvesting principle in NG consisting t-Te NW, it theoretically and experimentally found that NW piezoelectrically activated only by creating strain its radial direction, along which has an asymmetric...
Flexible and stretchable optoelectronic devices can be potentially applied in displays, biosensors, biomedicine, robotics, energy generation. The use of nanomaterials with superior optical properties such as quantum dots (QDs) is important the realization wearable displays biomedical devices, but specific structural design well selection materials should preferentially accompany this technology to realize forms these devices. Here, we report sensors manufactured using colloidal QDs...
Although titanium-based implants are widely used in orthopedic and dental clinics, improved osseointegration at the bone–implant interface is still required.
Successful rehabilitation with respect to the activities of daily living (ADL) requires accurate and effective assessment training. A number studies have emphasized requirement for methods that are both relevant patient's real world environment, can also be transferred other tasks. Virtual reality (VR) has many advantages over ADL techniques, offers potential develop a human performance testing training environment. Therefore, in this study, virtual supermarket was developed possibility...
We present a high-performance flexible triboelectric nanogenerator (TENG) based on an interlocked array of surface-functionalized indium tin oxide (ITO) nanohelix (NH) structures. The structural properties ITO NHs, including high nanoscale roughness and unique spring-like geometry, provide large surface area for effective friction, enhanced tolerance to bending strain, operational reliability. TENG device with NHs exhibits significantly (over 340 times) electrical output power compared the...
Considering the characteristics and operating environment of remotely controlled miniature soft robots, achieving delicate adhesion control over various target surfaces is a substantial challenge. In particular, ability to delicately grasp wrinkled biological nonbiological with low preload without causing damage essential. The proposed adhesive robotic system, inspired by secretions from velvet worm, uses structured magnetorheological material that exhibits precise stability repeatability...
We introduce a functional silane-based inorganic–organic hybrid layer (silamer) to significantly improve the environmental stability of ALD Al 2 O 3 films. Silamer-capped was shown be an effective candidate for application in wearable OLEDs.
Bone tissue regeneration is regulated by complex events, including inflammation, osteoinduction, and remodeling. Therefore, to induce the complete restoration of defective bone tissue, biomaterials with ability regulate collective regenerative system are beneficial. Although some studies conclude that reducing reactive oxygen species created a favorable environment for controlling can simultaneously promote osteogenesis inflammation have not been developed. Herein, we describe development...
Digital light processing three-dimensional (3D) printing technique is a powerful tool to rapidly manufacture plastic scintillators of almost any shape or geometric features. In our previous study, the main properties output and transmission were analyzed. However, more detailed study other required develop 3D printed with expectable reproducible properties. The scintillator displayed an average decay time constants 15.6 ns, intrinsic energy resolution 13.2%, detection efficiency 6.81% for...
ABSTRACT To develop a biodegradable epoxy resin matrix for high‐voltage insulating composites, petroleum‐based diglycidyl ether of bisphenol A (DGEBA) and epoxidized soybean oil (ESBO) were mixed, their biodegradability electrical mechanical properties studied. DGEBA/ESBO mixtures in the ratios 100/0, 90/10, 80/20, 70/30, 60/40, 50/50, respectively. In soil burial test, as ESBO content increased, thermosets disintegrated into smaller pieces by 4–6 months, while DGEBA thermoset without any...
The goal of video moment retrieval and highlight detection is to identify specific segments highlights based on a given text query. With the rapid growth content overlap between these tasks, recent works have addressed both simultaneously. However, they still struggle fully capture overall context, making it challenging determine which words are most relevant. In this paper, we present novel Video Context-aware Keyword Attention module that overcomes limitation by capturing keyword variation...
Abstract Background Fabrication of three-dimensional stem cell spheroids have been studied to improve function, but the hypoxic core and limited penetration nutrients signaling cues interior spheroid were challenges. The incorporation polymers such as silica gelatin in resulted relatively relaxed assembly composite spheroids, enhancing transport nutrient biological gas. However, because low surface area between cells since heterogeneously distributed throughout spheroid, these cannot...
