Removal of Arsenic (III) from groundwater applying a reusable Mg-Fe-Cl layered double hydroxide [PDF]

, 2014
BACKGROUND: Layered double hydroxide compounds (LDHs) have been applied for the removal of oxyanions including arsenate (As(V)). However, the aim of this present research is to develop a LDH to treat arsenite (As(III)).

Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

Advanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Non Thermal‐Driven Photocatalytic Ammonia Decomposition at Near‐Room Temperature on a Plasmonic Nanocone Array

Advanced Functional Materials, EarlyView.
Plasmonic photocatalytic ammonia decomposition occurs at near‐room temperature on a plasmonic Au nanocone array under visible light illumination. The nanostructure efficiently harnesses plasmonic modes, leading to increased reaction rates upon plasmon decay.

Removal and Reuse of Phosphorus as a Fertilizer from CAFO Runoff [PDF]

, 2019
Eutrophication is the process in which nutrient saturated waters promote algal blooms on the surface of the water. This limits the amount of dissolved oxygen content in the water, effectively limiting the range of species that can survive in a body of ...

Unassisted Photoelectrochemical Hydrogen Production Coupled with Selective Glucose Oxidation Using Metal Halide Perovskite Photoanodes

Advanced Functional Materials, EarlyView.
A metal halide perovskite‐based photoanode integrated with a CoNiFe layered double hydroxide (LDH) cocatalyst is reported for selective glucose oxidation reaction (GOR), achieving simultaneous and unassisted photoelectrochemical hydrogen production. This system delivers high photocurrent density, excellent Faradaic efficiency of GOR, and strong techno ...

Kinetic Insights into Precursor‐Assisted Soft Sphere Close Packing Revealed by In Situ GISAXS with Implications for Gas Sensing

Advanced Functional Materials, EarlyView.
The versatile precursor‐assisted soft sphere close packing during slot‐die coating is investigated with in situ X‐ray scattering. The soft crystallization pathways towards a close packing involve multistep structural transitions such as surface nucleation, in‐plane, and out‐of‐plane crystallization.

Kinetics of Enzyme Adsorbed on Adsorbent

The Journal of the Society of Chemical Industry, Japan, 1969
酵素をその活性を保ったままで不溶化し,基質と反応させようとする考え方は,酵素の研究,利用という面から多くの利点を与えるものと考える。著者らはその方法の一つとして吸着剤に酵素を吸着させることによって,水に不溶なcomplexを調製しているが,本報では被吸着酵素の動態を考察するためにMichaelis定数および最大速度を測定した。すなわち,酵素としては市販の糖化型アミラーゼを使用し,これを活性炭または酸性白土に吸着させてcomplexを調製し,これを種々な濃度の基質と反応させたところ,Michaelis定数はいずれもnative酵素より増加し,最大速度は減少した。これにより,吸着剤表面の酵素はかなり構造上の変化を受けていることがわかった。また吸着剤の種類によって ...
