Electrically Coded Retinomorphic Spectrophotodetector

Advanced Materials, EarlyView.
Self‐powered retinomorphic pyro‐photodetector is demonstrated that avoids machine‐learning post‐processing and covers 365–940 nm. Electrostatic balancing of built‐in potential produces an electrical wavelength code, delivering <3 nm wavelength decoding accuracy with ∼46 µs response.

The Latest Frontiers of Bubble Columns and Slurry Bubble Columns. Flow Characteristics in Bubble Column with Draft Tube and Performance Improvement.

KAGAKU KOGAKU RONBUNSHU, 2001
ドラフトチューブ付気泡塔の流動特性について装置因子の観点から，とくにドラフトチューブ長さ，上下の隙間の長さ等の影響を検討した．液混合時間に及ぼす塔のアスペクト比（塔高/塔径）の影響および液循環流量に及ぼすドラフトチューブ上端から通気時の液面までの距離の影響を明確にした．また，気液の循環流量の関係を示した．次に，ドラフトチューブを改良した研究を紹介した．多孔ドラフトチューブを挿入した気泡塔では，特異な流動挙動により，気液物質移動および液混合性能が大きく改善されることを示した．また，充填物・向流式気泡塔と多孔ドラフトチューブとの組合せ等の一連の研究および高粘性液における性能改善や排水処理への応用研究の結果を示し，考察を加えた．さらに ...

Angstrom‐Scale Confined Ion Sieve and Accelerator for Efficient Aqueous Zinc Batteries

Advanced Materials, EarlyView.
An angstrom‐scale confined ion accelerator strategy is proposed for ultra‐stable aqueous Zn anodes. Selective and precise transport of hydrated Zn(H2O)62+, Zn2+ cations, H2O molecules, and SO42− anions is achieved by in‐plane atomic Ti vacancies and angstrom‐scale interlayer free spacing within the Ti0.87O2 interfacial layer, leading to homogeneous Zn ...

S‐Nitrosothiols as Thiol‐Protecting Groups for Controlled Thiol‐Maleimide Crosslinking of Homogeneous Soft Hydrogels

Advanced Materials, EarlyView.
Rapid thiol‐maleimide addition frequently outpaces mixing, resulting in heterogeneous hydrogels. S‐nitrosothiols act as thiol‐protecting groups, allowing uniform mixing with maleimide‐functionalized polymers before gelation. Sodium thiosulfate or sodium ascorbate then regenerates thiols on demand, triggering controlled thiol‐maleimide crosslinking ...

Bubble Properties in Bubble Columns with Electrolyte Solutions

Korean Chemical Engineering Research, 2016
− Bubble properties such as size (chord length) and rising velocity were investigated in a bubble column with electrolyte solutions, of which diameter was 0.152m and 2.5m in height, respectively. The size and rising velocity of bubbles were measured by using the dual electrical resistivity probe method.
