The failure mechanism of silicon-based electrodes has been studied only in a half-cell configuration so far. Here, a combination of 7Li, 19F MAS NMR, XPS, TOF-SIMS, and STEM-EELS, provides an in-depth characterization of the solid electrolyte interphase (SEI) formation on the surface of silicon and its evolution upon aging and cycling with LiNi1/3Mn1/3Co1/3O2 as the positive electrode in a full...
With the advent of low-cost and high-performance depth sensors, the usage of threedimensional (3D) point clouds is becoming attractive and increasingly popular. Meanwhile, there is a growing demand to process and understand the 3D data. 3D scan registration is the cornerstone of several advanced 3D data processing techniques, and the odometry-free scan registration of 3D point clouds is a resea...
Introduction: Deep heated oils produce toxins that endanger people's health. The current study aims to investigate the simultaneous effect of aerobic training and Octopamine consumption on the mitophagy of brown adipose tissue after the induction of intoxication through deeply heated oil in male wistar rats. Method: 40 male wistar rats after four weeks of feedi...
Existing specific emitter identification (SEI) methods based on hand-crafted features have drawbacks of losing feature information and involving multiple processing stages, which reduce the accuracy emitters complicate procedures identification. In this paper, we propose a deep SEI approach via multidimensional extraction for radio frequency fingerprints (RFFs), namely, RFFsNet-SEI. Particularl...
CONTEXT By absorbing sunlight UVB and thereby reducing cutaneous vitamin D photosynthesis, ozone, a common urban pollutant, could cause hypovitaminosis D. OBJECTIVES The objective of the study was to establish the characteristics and percentage of subjects with serum 25-hydroxyvitamin D [25(OH)D] less than 75 nmol/liter among postmenopausal women engaging in outdoor activities in either Bruss...
Solid-electrolyte interphase (SEI) is the key component that enables all advanced electrochemical devices, the best representative of which is Li-ion battery (LIB). It kinetically stabilizes electrolytes at potentials far beyond their thermodynamic stability limits, so that cell reactions could proceed reversibly. Its ad hoc chemistry and formation mechanism has been a topic under intensive inv...
BACKGROUND Advance Technology Development (ATD) Program is a new program put forth by Department of Energy to develop high power lithium ion batteries for hybrid electric vehicles and electric vehicles. It is a joint effort of five national labs and LBNL is the lead lab in investigating SEI (solid electrolyte interface) layer formation and dissolution. Our group is responsible for the character...
BACKGROUND Social exclusion (SE) refers to the inability of certain groups or individuals to fully participate in society. SE is associated with socioeconomic inequalities in health, and its measurement in routine public health monitoring is considered key to designing effective health policies. In an earlier retrospective analysis we demonstrated that in all four major Dutch cities, SE could l...
