Studies on the Formation of Ferrites by Hydrothermal Method

Journal of the Japan Society of Powder and Powder Metallurgy, 1969
The crystal size of the ferrites formed hydrothermally from the mixtures of 2α-FeOOH +Zn(OH)2, 2α-FeOOH+NiO or 2α-FeOOH+Co(OH)2, was found to depend on the pH of the medium, and large cubic crystals were observable in alkaline medium, in which complex ions bearing Zn++, Ni++ or Co++ were stable.In case of the synthesis of these ferrites from ...

Orbital‐Hybridizable Nanoseed Interphase Enables One‐Minute Rechargeable, Energy‐Dense Anode‐Free Aqueous Zinc Batteries

Advanced Materials, EarlyView.
An orbital‐hybridizable nanoseed (OHNS) interphase induces strong orbital hybridization between Zn and carbon edges, accelerating Zn nucleation while suppressing 2D surface diffusion. This interfacial electronic regulation drives uniform, dense, and (002)‐oriented Zn growth, enabling stable and fast charging behavior in anode‐free aqueous Zn batteries.

Indium‐Mediated Glue‐Like Interlayer Enables Stable High‐Capacity Flexible Sodium Metal Batteries

Advanced Materials, EarlyView.
A three‐dimensional Na‐In‐S/Cu composite interlayer is constructed on a flexible current collector via an In‐mediated in situ reaction. Featuring abundant Na nucleation sites and a low diffusion barrier, this interlayer enables rapid and uniform Na deposition.

Carbonization of Cellulose Using the Hydrothermal Method

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2008
Cellulose was treated at 423–623 K under hydrothermal conditions without a catalyst to produce charcoal. The charcoal generated under hydrothermal conditions was mainly analyzed by FT-IR in order to investigate changes in its chemical structures occurring during the carbonization process.

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

Advanced Materials, EarlyView.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Co1/Ru Single‐Atom Alloy Catalyst for Sustainable Polypropylene Hydrogenolysis to Long‐Chain Liquid Products

Advanced Materials, EarlyView.
A titania‐supported Co1/Ru single‐atom alloy catalyst enables efficient polypropylene hydrogenolysis. Ru─Co─Ru motifs maintain Ru activity while suppressing excessive chain scission to gaseous products. Both virgin and waste plastics achieve high, environmentally and economically optimal C11+ liquid yields, supporting sustainable chemical recycling ...

Preparation of Hydroxyapatite Whiskers by Hydrothermal Method.

NIPPON KAGAKU KAISHI, 1995
ヒドロキシアパタイト(HAp)の化学的性質の一つである結晶学的異方性を積極的に活用するため,c軸方向に伸長したホイスカー状HAp結晶を合成する方法について検討した.湿式法で調製したHApスラリーにクエソ酸を加えて溶解した液をオートクレープに入れて,180～220℃,0～10時間の条件で水熱処理した.固形分濃度1.7wt%のHApスラリーから調製した試料の場合,200℃,3時間以上の水熱処理により,長さ10～30μm,直径約0.5μmのHApホイスカーが単相で得られた.しかし,3時間未満の水熱処理では且Apとモネタイトの混合相が析出して,時間が短いほどモネタイトの割合が高かった.これに対して,固形分濃度4.4wt%のスラリーを用いた場合には,クエソ酸添加量を変化させても ...
