Herein, we present a gel polymer electrolyte (GPE) improving nonflammability of lithium-ion batteries (LIBs) by blocking radical-initiated chain reactions which cause thermal runaway and finally fire issues. The that makes up the nonflammable GPE was (1) soluble in carbonate electrolytes, (2) cross-linkable presence popularly used lithium salt such as LiPF6, (3) gelated only with 2 wt % (4) radical-scavenging its functional side chains. Electrolytes having were thermally within battery cells...
This letter proposes a new mechanism, four-bar linkage-based support hinge for assisting with shoulder abduction artificial muscle based on shape memory alloy (SMA). An using the SMA coils is designed to lighten entire system and wearer's movement both actively passively. It can generate up 273 N 180 without energy input, respectively, while weighing only 0.04 kg. Furthermore, consider rotation axis shifts of arm during abduction, trajectory along modeled scapulohumeral rhythm, combined...
For designing the assistive wearable rehabilitation robots, it is challenging to design robot as energy efficient because actuators have be capable of overcoming human loads such gravity body and spastic torque continuously during assistance. To address these challenges, we propose a novel soft artificial muscle that utilizes shape memory alloy (SMA) spring with pre-detwinning process. The SMA was fabricated through process called pre-detwinning, which enhances linearity in martensite phase...
Shape-morphing displays alter their surface geometry to convey information through three-dimensional shapes. However, rapid transformation into seamless shapes with multimodal tactile sensations poses challenges. Here, we introduce a versatile soft shape-morphing and display, using novel actuator that combines PVC gel composite, dielectric liquid, an electrode array. Proposed device facilitates on-demand liquid flow control electrohydraulic actuation. Liquid channels within the can be...
The insertion of lithium into manganese oxide spinel (LiMn2O4 (LMO) to Li2Mn2O4 (L2MO)) was used store light energy as a form chemical in dye-sensitized photorechargeable battery (DSPB). Herein, we investigate the effect crystallite size LMO on DSPB performance. graphene-wrapped submicrometer-sized (LMO@Gn) tuned electrochemically from 26 34 nm via repeated LMO-to-L2MO transitions. different orientations LMO@Gn particles were ordered an identical direction by electric stimulus. having (L34...
An 8-year-old girl with a renal transplant was admitted for myalgia and muscle weakness in both legs over the previous 2 weeks. She also had fever intermittent epigastric pain. Based on these clinical manifestations, laboratory histopathological findings, diagnosis coincidence of late-onset cytomegalovirus (CMV)-induced myositis gastritis an immunocompromised child transplant. After administration intravenous ganciclovir 3 weeks, her symptoms resolved, normalization abnormal enzymes,...
<title>Abstract</title> The electric heaters based on functional material and design have been developed to realize the various multifunctional applications. In this work, heater consisting of polyvinyl chloride (PVC)-gel hydrogel electrode, for first time, is proposed, which exhibits high stretchability, transparency capacity generate diverse thermal patterns through spatially localized heating. proposed capable generating uniform temperature distribution at heated area under extreme...
Chronic kidney disease (CKD) requires management in daily life; accordingly, psychosocial development of pediatric patients with CKD is greatly affected due to delayed growth, frequent absences from school, and difficulties engaging normal activities peer relationships CKD. This study was investigate the mental health problems children adolescent KoreaN cohort for Outcome Pediatric Kidney Disease (KNOW-Ped CKD).
The shape changes by bending and twisting of a SMA/composite panel with embedded SMA wire actuators controlled both electric resistive heating passive elastic tailoring are investigated to realize the morphing wing unmanned aerial vehicles. Three-dimensional finite element formulations derived used analyze behaviors smart structures. numerical results show that shapes panels can be judicious choices control temperatures, angles, tailoring. To validate analytical results, two SMA-embedded...
