Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.

Low‐Frequency Noise and Stability in Electrolyte‐Gated Nanoscale Silicon Field‐Effect Transistor Sensors

Small Methods, EarlyView.
Electrolyte‐gated nanoscale silicon field‐effect transistor sensors provide exceptional charge sensitivity and direct electrical readout. However, their sensing accuracy is fundamentally limited by low‐frequency noise and baseline drift. This review examines the origins of noise and drift in these sensors, summarizes the key mitigation strategies, and ...

Key Aspects Of The Debinding & Sintering Atmosphere For 17-4 PH Stainless Steel Fabricated Via Binder Jetting

, 2023
Binder Jetting (BJT) of metals is a multi-step process that relies on the sintering of printed parts to reach the intended material properties. A crucial but often overlooked step after printing is debinding, which is impacted by the processing ...

Improved mechanical quality of ceramic vat photopolymerization prints by supercritical carbon dioxide extraction

Open Ceramics
Vat photopolymerization (VPP) enables 3D printing of dense ceramics with complex structures, however the mandatory thermal pre-conditioning and debinding steps to remove the organic substances, can last 7 days.

Effect of Cigarette Smoking on the Surface Roughness, Color, and Translucency of Zirconia Produced by Additive and Subtractive Manufacturing

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To compare the surface roughness, color stability, and translucency of zirconia produced by additive manufacturing (AM) and subtractive manufacturing (SM) after exposure to cigarette smoking. Materials and Methods A total of 60 disc‐shaped specimens were fabricated from 2 methods: AM (INNI Cera BCM W500/1000) and SM (VITA YZ T).

IN SITU DIMENSIONAL CHANGES OF POWDER INJECTION-MOLDED COMPACTS DURING SOLVENT DEBINDING

, 1998
—Defects such as cracking, slumping, and sagging are frequently found in powder injection-molded (PIM) compacts. These defects are partly related to the swelling of the binders during solvent debinding.

Bond strength enhancement for additively manufactured zirconia: Micro‐retentive design approach

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of digitally designed micro‐retention features on the bond strength of additively manufactured (AM) zirconia copings. Materials and Methods Sixty titanium base abutments (NobelParallel, NobelBiocare), pretreated with 50 µm alumina particles were divided into four groups (n = 15 per group); one group with ...
