Hydrothermally Stable Cu‐SAPO‐34 From Attapulgite by Dual‐Silane Modification for NH3‐SCR

cMat, Volume 3, Issue 2, June 2026.
ABSTRACT For ammonia‐selective catalytic reduction (NH3‐SCR) catalysts, critical performance metrics include a broad operating temperature window, high nitrogen oxides (NOx) conversion efficiency, near‐unity N2 selectivity, and long‐term durability under harsh hydrothermal conditions.

CHARACTERISTICS OF THIN FILMS SYNTHESIZED FROM NANO BOEHMITE AND ORGANOALKOXYSILANE

, 2010
We investigated the properties of inorganic–organic hybrid thin films prepared by sol–gel reaction. Sol solutions were synthesized by using two kinds of nanosized boehmite and methyltrimethoxysilane (MTMS) in variation with the amount of MTMS at ...

Tailoring of Waste‐Derived CO2 Adsorbents From the Perspective of Apparent and Intrinsic Property Regulation

cScience, Volume 2, Issue 2, June 2026.
ABSTRACT The conversion of waste materials into solid CO2 adsorbents is a promising strategy for carbon capture and waste management. In this review, we discuss recent advances in the preparation and modification of waste‐derived CO2 adsorbents, including carbon‐based materials, zeolites, metal–organic frameworks, layered double hydroxides, CaO, and ...

Boehmite-bonded high-alumina refractories [PDF]

, 1979
High-alumina refractories (99+ % Al₂O₃) were produced by pressing a mixture of 70% tabular alumina and 30% reactive alumina and autoclaving in saturated steam at 1.4 MPa (200 psia)/194 °C to 3.4 MPa (500 psia)/242 °C for 12 to 96 h. Autoclaving converted

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

Advanced Materials, Volume 38, Issue 30, 27 May 2026.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

Synthesis and Characterization of Nanoporous Boehmite

Journal of Korean Powder Metallurgy Institute, 2005
Boehmite (AlOOH) powder with uniform pore size and high specific surface area were synthesized via sol-gel method using metal salts, and . During these synthetic process, the effects of the aging time were investigated to determine the optimal synthetic conditions of boehmite.

Weakening Processes in Carbonate‐Hosted Faults: Phyllosilicate Microlayers and Injections Along the Mattinata Fault (Southern Italy)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Micrometric phyllosilicate films along fault slip surfaces (SSs) can drastically reduce friction, yet they are unexpected in clay‐poor carbonate platforms. We inquire how a major carbonate‐hosted, seismogenic strike‐slip fault can develop weak slip interfaces and undergo dynamic weakening despite an intrinsically strong host rock.

Boehmite-Bonded High Alumina Refractories

, 1980
The objective of the present study was to investigate the feasibility of producing boehmite-bonded, high alumina refractories. The optimum autoclaving conditions, saturated steam pressure, and exposure time were determined within assumed technological ...

Improving reaction uniformity of high‐loading lithium‐sulfur pouch batteries

Carbon Energy
Lithium‐sulfur batteries (LSBs) have garnered attention from both academia and industry because they can achieve high energy densities (>400 Wh kg–1), which are difficult to achieve in commercially available lithium‐ion batteries.
