We developed the novel electrode that enables fine control of overpotential by exploiting surface segregation is enrichment one component at binary alloy. To realize this approach, we controlled proportion Si with low Li diffusivity annealing SiGe nanowire in H2 environment various temperatures. The resulting nanowires annealed 850 °C exhibited high reversible capacity (>1031 mA·h·g–1), and long cycle life (400 cycles) retention (89.0%) 0.2 C. This superior battery performance attributed to...
Background: Patient verification by unique identification is an important procedure in health care settings. Risks to patient safety occur throughout settings failure correctly identify patients, resulting the incorrect patient, site procedure, medication, and other errors. To avoid medical malpractice, radio-frequency (RFID), fingerprint scanners, iris technologies have been implemented The drawbacks of these include possibility lose RFID bracelet, infection transmission, impracticality...
This article presents the efficacy of heat-induced MPC-grafting against excessive fibrous capsule formation and related inflammation in tissues surrounding silicone breast implants inserted a pig model.
The implementation of through-silicon vias for high-performance semiconductor devices requires a reliable fabrication process that can achieve high aspect ratio (HAR) silicon nanoholes (Si NHs). Currently, Si NHs are primarily fabricated via plasma-based dry etching, which has technical limitations, such as necking and bowing. Metal-assisted chemical etching (MaCE) is an alternative NH method utilizes wet chemistry catalyzed by metals. However, the formation HAR challenging because unstable...
The surface of human silicone breast implants is covalently grafted at a high density with 2-methacryloyloxyethyl phosphorylcholine (MPC)-based polymer. Addition cross-linkers essential for enhancing the and mechanical durability MPC graft. graft strongly inhibits not only adsorption but also conformational deformation fibrinogen, resulting in exposure buried amino acid sequence, γ377–395, which recognized by inflammatory cells. Furthermore, numbers adhered macrophages amounts released...
We present a low-power CMOS active-resistance-capacitance (active-RC) complex bandpass filter (BPF) with tunable gain, bandwidth, center frequency, quality factor, and passband flatness for Bluetooth applications. A transfer function analysis cross-coupled Tow-Thomas biquad structure is presented to prove that the profile of gain can be effectively controlled by independently tuning two cross-coupling resistors. The proposed biquad-based BPF was employed realize fourth-order baseband analog...
본 논문에서는 전자종이 디스플레이 스마트 카드를 위한 초소형 CMOS 다중 스위치 반도체 집적회로를 설계 및 제작하였다. 칩은 SPST (Single Pole Single Throw) 4개와 SPDT Double 8개로 구성되어있으며, 각각의 상태는 외부의 제어신호에 의해 설정될 수 있도록 하였다. 0.25μm 공정을 사용하여 회로를 설계하였으며, 설계된 칩의 크기는 2.25×2.25 mm²이다. 트랜지스터 수준의 회로 레이아웃 효과를 포함한 시뮬레이션을 통하여 회로가 공정, 전압 온도 (PVT) 변화 환경에도 목표 성능을 만족함을 확인하였다. 연구의 스위치회로를 단일 칩 회로로 개발하고 적용함에 따라, 카드의 기판 면적을 소형화할 있으며, 축소된 면적만큼 배터리 공간 증가에 활용할 있어서, 결과적으로 전체 시스템의 동작시간을 증가시킬 있었고, 휘어짐에 대한 내구성을 강화시키는 얻을 있었다.
Background: Nearby citizens were exposed to large volumes of volatile organic compounds (VOCs) for four days after the Hebei Spirit oil spill.Objectives: To investigate cross-sectional and longitudinal relationships between initial exposure VOCs in children loss pulmonary function 1, 3, 5 years event.Methods: Cumulative ambient VOC concentrations over immediately spill, including benzene, toluene, ethylbenzene, xylene, total (TVOCs), measured with a modeling technique. The forced expiratory...
본 연구에서는 알고리즘의 수행시간 분석에 초점을 맞춘 언플러그드 방식의 교육이 초등학교 3학년 학생들의 컴퓨팅 사고력 향상에 미치는 효과를 분석해보았다. 현직 초등교사 70명과 학생 120명을 대상으 로 실시한 요구분석 결과를 바탕으로, ADDIE 모형의 절차에 따라 교육프로그램을 개발하였다. 개발 한 교육프로그램으로 24명에게 총 6일 동안 36시간의 수업을 진행하였고, 같은 시간 보드게임 교육을 받은 24명의 학생들과 사전·사후 비교 검사를 통해 분석하였다. 분석 결과, 교육은 사고력에 긍정적인 효 과를 것으로 확인되었다.
