Highly Permeable CeO2 Porous Hollow Microspheres with Multilevel Gas Channels for Rapid NH3 Gas Response and Recovery Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this study, a series of highly permeable CeO2 porous hollow microspheres with multilevel gas channels and tunable pore sizes were first prepared via the hydrothermal method, achieving rapid response and fast recovery to ammonia gas. Fast response and recovery performance is highly significant for real‐time monitoring of NH3 gas due to the toxic and ...

Advanced process development for contacts to algan/gan high electron mobility transistors (HEMTS) [PDF]

, 2009
High work function metals--Ni, Pt, Ir, and Au--were comparatively studied as Schottky metallizations to GaN and AlGaN/GaN heterostructures. Ni/Au, Ni/Pt/Au, Ir/Au, Ir/Pt/Au and Pt/Au Schottky diodes were fabricated on GaN and AlGaN/GaN substrates ...

Enhancement of Electro-Optical Characteristics in GaN-Based Ultraviolet Laser Diodes Through Upper Optical Confinement Structure Design

Nanomaterials
Two series of laser diodes with different AlGaN cladding layers were investigated, and it was found that the internal absorption loss was reduced by using a u-AlGaN and p-AlGaN composite upper cladding layer, and the performance of LD was improved.

Postoperative Hypocalcemia Following Total Thyroidectomy Versus Completion Thyroidectomy

The Laryngoscope, EarlyView.
Completion thyroidectomy performed with at least a three‐month interval demonstrates superior parathyroid preservation compared to primary total thyroidectomy, as evidenced by significantly higher postoperative parathyroid hormone levels (51.90 ± 30.26 pg/mL vs. 30.90 ± 17.10 pg/mL, p = 0.006).
