Micropleated Nanofibrous Filters for High‐Efficiency Submicron Aerosol Filtration: A Comparative Study with Chemical, Biological, Radiological, and Nuclear Gas Mask Filters

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents micropleated filters manufactured by needleless electrospinning. Nanofibers are deposited onto uniaxially pre‐stretched substrates that contract upon release, forming densely packed micropleats. This architecture increases effective surface area without enlarging the filter size, achieving quality factors comparable to those of ...

Development and Preliminary In Vivo Study of 3D‐Printed Bioactive Glass Scaffolds with Trabecular Architecture

open access: yesAdvanced Engineering Materials, EarlyView.
This study reports the fabrication of trabecular bioactive glass scaffolds (composition “1d”: 46.1SiO2‐28.7CaO‐8.8MgO‐6.2P2O5‐5.7CaF2‐4.5Na2O wt%) through vat photopolymerization and the relevant results from mechanical testing and in vivo implantation procedures in rabbit femora, showing great promise for bone tissue engineering applications.

Asymmetric Radical Polymerization.

open access: yesKOBUNSHI RONBUNSHU, 2001
メタクリル酸1-フェニルジベンゾスベリル (PDBSMA) およびN-フェニルおよびN-シクロヘキシルマレイミド (PMI, CHMI) のラジカル重合における不斉誘導について検討した. PDBSMAはラジカル重合でもほぼ完全にイソタクチックならせん状ポリマー (左右のらせんの等量混合物) を与える. 本研究では, PDBSMAのラジカル重合を, 光学活性な開始剤 (過酸化物), 連鎖移動剤 (チオール), 溶媒 (アルコール類), あるいは不対電子をもつ添加剤 (コバルト (II) 錯体) を用いて行うことにより, 左右どちらかに偏ったらせん構造をもつ光学活性ポリマーを合成した (らせん選択ラジカル重合).

Ultraviolet and thermally stable polymer compositions [PDF]

open access: yes, 1976
A new class of polymers is provided, namely, poly (diarylsiloxy) arylazines. These novel polymers have a basic chemical composition which has the property of stabilizing the optical and physical properties of the polymer against the degradative effect of

Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

open access: yesAdvanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.

Radical polymerization approach for ring opened oxanorbornene anhydride based macromonomers

open access: yesDesigned Monomers and Polymers, 2018
In this work, we synthesized end group functionalization of the cis-Norbornene-5-6-endo-dicarboxylic anhydride species via the ring-opening metathesis polymerization (ROMP) of oxanorbornene derivatives generated a chiseled poly(cis-Norbornene-5-6-endo ...

What Do Large Language Models Know About Materials?

open access: yesAdvanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...
