This paper reports the application of anthracite particles of different sizes and coated with nine kinds of layered double hydroxides (LDHs) varying in M(II)-M(III) cations, as alternative substrates in the simulated vertical-flow constructed wetland columns. Effects of LDHs-coating and particle size of modified anthracites were examined to evaluate their abilities in removing oxygen demand and...

Layered double hydroxides (LDHs) exhibit characteristic anion-exchange chemistry making them ideal carriers of negatively charged molecules like deoxyribonucleic acid (DNA). In this study, hydrotalcite (Mg-Al) and hydrotalcite-like compounds (Mg-Fe, Zn-Al, and Zn-Fe), also known as LDHs, were evaluated for their potential application as a carrier of DNA. LDHs were prepared by coprecipitation at...

The synthesis method of layered double hydroxides (LDHs) determines nanoparticles' performance in biomedical applications. In this study, hydrothermal treatment as an important synthesis technique has been examined for its influence on the physicochemical properties and the drug release rate from drug-containing LDHs. We synthesised MgAl-LDHs intercalated with non-steroidal anti-inflammatory dr...

Efficient and cost-effective removal of radioactive pertechnetate anions from nuclear waste is a key challenge to mitigate long-term nuclear waste storage issues. Traditional materials such as resins and layered double hydroxides (LDHs) were evaluated for their pertechnetate or perrhenate (the non-radioactive surrogate) removal capacity, but there is room for improvement in terms of capacity, s...

In article 1600229, Shilong Wang, Rongrong Zhu, Yechang Qian, and co-workers investigate the anti-metastatic and anti-angiogenic effects of SiO2@LDH (LDH: layered double hydroxide) loaded with etoposide (VP16). SiO2@LDH has very suitable qualities as drug delivery agent and enhances the anti-metastatic action of VP16 both in vitro and in vivo. Enhanced anti-angiogenic efficacy is also proven wh...

Among the nanomaterials reported in literature, layered double hydroxides (LDHs) are considered promising for electrochemical sensor technology. Transition metal-based (TM-LDHs) show excellent electrocatalytic properties that facilitate redox reactions with analytes, e. g. H2O2, glucose or glyphosate. Elaboration of porous nano-structures TM-LDHs nanosheets on electrode surface allows a rapid d...

(1) Background: In time, stone monuments suffer a process of aging and loss aesthetic mechanical properties. order to restore stop the their properties, various treatments are used, in this context, new class discovered materials with interesting properties layered double hydroxides, or LDHs. (2) Methods: The LDHs, prepared by coprecipitation method, were characterized structure X-ray diffracti...
