Design And Fabrication of Condenser Microphone Using Wafer Transfer And Micro-electroplating Technique [PDF]

open access: yes, 2008
A novel fabrication process, which uses wafer transfer and micro-electroplating technique, has been proposed and tested. In this paper, the effects of the diaphragm thickness and stress, the air-gap thickness, and the area ratio of acoustic holes to ...

Aberrant Glycosylation of IgG in Children With Active Lupus Nephritis Alters Podocyte Metabolism and Causes Podocyte Injury

open access: yesArthritis &Rheumatology, EarlyView.
Objective Podocytes are integral to the maintenance of the glomerular filtration barrier. Their injury results in proteinuria and disease progression in lupus nephritis (LN). Aberrant IgG glycosylation drives podocyte injury in LN and leads to cytoskeletal rearrangement, motility changes, and decreased nephrin production.

Expert Perspective: Diagnosis and Treatment of Castleman Disease

open access: yesArthritis &Rheumatology, Accepted Article.
Summary Castleman disease (CD) is a major diagnostic challenge for Rheumatologists. Unicentric CD (UCD) involves one enlarged lymph node region whereas multicentric CD (MCD) involves multiple enlarged lymph node regions. Both UCD and MCD may exhibit a wide range of symptoms that overlap with other immune‐mediated conditions.

Improving Low‐Temperature Tolerance of a Lithium‐Ion Battery by a Localized High‐Concentration Electrolyte Based on the Weak Solvation Effect

open access: yesBattery Energy, EarlyView.
In this paper, we designed a localized high‐concentration electrolyte based on weak solvation (Wb‐LHCE) by introducing FB as a diluent in a weak solvating solvent THF, which not only ensures good wettability between the electrolyte and the electrode at low temperatures but also induces the formation of a solvation structure rich in anions.
