Product Overview

Layered double hydroxides (LDHs) are 2D hydrotalcite materials consisting of a positively charged main layer and exchangeable interlayer anions. Generally, it can be expressed as [M2+1-xM3+x(OH)2]x+[(An-)x/n]x-·mH2O (M2+ and M3+ are bivalent Ni2+, Co2+, Fe2+ and trivalent metal ions Al3+, V3+ and Cr3+, respectively, and An- is an interlayer anion (carbonate and nitrate). x is the molar ratio of M3+/(M2++M3+). For the preparation of LDHs, the main preparation methods include chemical precipitation, hydrothermal method, solvothermal method and so on. 1. The chemical precipitation method uses homogeneous chemical precursors as the substrate material, in which two or more metal ions are intricately mixed together and produce synergies to form the desired material. The main preparation process is to dissolve the bivalent and trivalent metal nitrate chemicals in deionized water with a certain molar ratio, and stir for a period of time at the appropriate temperature (generally 60 ° C), and then add the NaOH solution drop by drop and maintain the pH of the solution at about 10 ~ 11, stir for a period of time, and place it at the appropriate temperature after aging. 2. Hydrothermal method is usually used to enhance the crystallinity of layered double hydroxides. Hydrothermal method can obtain well-crystallized and evenly layered double hydroxides. The main preparation process is to mix the bivalent and trivalent metal nitrate chemicals and urea in aqueous solution to form a homogeneous solution in a certain ratio, and then add it to the reaction kettle for the corresponding time to prepare. 3. Solvothermal method is a simple and environmentally friendly method. Similar to the hydrothermal method, the difference is that hydrothermal is to mix two metals in an aqueous solution to form a homogeneous solution, while solvothermal is to mix two metals in an organic solution to form a homogeneous solution, and then put it into the reactor at a higher temperature reaction preparation.

Product Features

 

Adjustability: Suitable metal ions can be selected according to the needs of the catalyst for type or quantity modulation, so as to obtain different functions of LDHs.

Structural memory effect: LDHs can be converted into relatively stable bimetallic oxide LDOs under high temperature roasting conditions, which has good thermal stability and multi-layer pore structure, and has been widely used in the field of electrochemistry.

Strippable layer and assembly: The interaction force between LDHs laminates is relatively weak, and it is easy to be destroyed by external forces, and it is stripped into a single-layer nanosheet structure.

 

Application Fields

 

 

Electrolytic water oxygen/hydrogen evolution reaction: LDHs containing transition metal ions Fe, Co, Ni, Mn, etc., is a good OER catalyst. For example, NiFe LDHs is one of the catalysts with the best OER properties, and is also considered to be a promising non-precious metal based OER electrocatalyst. LDHs can effectively adsorb hydroxyl species, such as CoNi-LDHs has good HER activity under alkaline conditions, and its activity is much higher than Ni(OH)2 and Co(OH)2.

Biomedical field: Good biocompatibility, low toxicity, lamellae structure can accommodate biomolecules, such as the use of CoMn-LDH nanosheets loaded with photosensitizer Ce6 for photodynamic/chemokinetic synergistic therapy to inhibit tumor growth.

Ion adsorption: Due to the special layered structure of LDHs and the strong ion exchange characteristics of interlayer anions, LDHs materials are usually used for the adsorption of heavy metal ions in sewage, such as selenium (VI), arsenic (III, V) and so on.

Supercapacitors: Layered metal hydroxide is a typical Faraday pseudocapacitor material, which has a high theoretical specific capacitance and is a promising electrode material for supercapacitors. LDHs has a large specific surface area, more active sites and a short diffusion distance, which facilitates the rapid migration of ions between the nanosheet surface and the electrolyte, thus significantly improving the Coulomb efficiency of the device.

“There are darknesses in life and there are lights. You are one of the lights...The light of all lights.” - Master of Salt & Bones. REVIEW: This book follows Isa who lives with her aunt on an island. Isa begins a new job as a caretaker for the dark, and mysterious Blackthorne family. A family who is disliked and even feared by the rest of the inhabitants of the island. However, as she grows closer to the man who they call the devil, Lucian Blackthorne, Isa sees for herself what the truth of Blackthorne manor really is. This book is a dark romance! Originally I was told it was fantasy, which I don’t agree with at all. It is more of an erotic, gothic feel with some mystery sprinkled in. The plot was very interesting and kept me intrigued. This book was also quite steamy, however, I felt those scenes were well done and didn’t take away from the rest of the book. Overall, the content in this book is quite dark and the backstories of the characters involve potentially triggering matters. Be aware to look these up if you feel like you need to. Overall, this is the first book I have read by Keri Lake, and I am excited to read more. SYNOPSIS: When I was a little girl, I dreamed a handsome knight would come and rescue me from my wretched mother. He'd ride up on his white steed and break the curse I've been fated to carry since the day I was born. Funny how things changed over time. How the fairy tale twisted into something far more crooked, darker than I ever imagined. In reality, my knight is scarred and broken, living alone in a castle of bones that overlooks the sea. He isn’t searching for me. He never was. Lucian Blackthorne is as cursed as I am, and equally shunned by the locals, the fishers of men, who believe him to be the devil in the flesh. Perhaps he is, with the way his amber eyes draw me in, ignite me like an infernal blaze. And the sins he whispers in my ear are as wickedly intoxicating as the man himself. Yet, his touch is heaven and his will is my weakness. He calls us forbidden, an unsalvageable tragedy, with no happy end. Maybe we are. But in this story, he’s the one who needs saving.

Master of Salt & Bones by Keri Lake review (no spoilers) ♾️/5 ⭐️ 4/5🌶️ 🏰gothic dark romance 🎹murder/mysteries 🏰age gap 🎹spicy 🏰touch her & d!e 🎹secret society 🏰dual POV & a past timeline for Lucian “we’re the composers, the conductor’s of our own fate, and we write the notes to a beautiful, dark melody that no one else can hear.” this book was AMAZING ❤️‍🔥 i couldn’t put this book down for anything . this book gives beauty & the beast / phantom of the opera vibes with a lot more going on . Lucian hires Isadora to help take care of his mom, not his nurse but a companion for her . Isadora has a painful past & she’s willing to do anything to get out of town to make some money , even if that means working for a guy with a thousand bad rumors about him . the way Lucian talks to Isadora is like he’s speaking poetry without even trying . the wording & quotes in this book were chiefs kiss . the spice in this book was gold 🔥 the plot of this book is super original & sooooo twisty . i think there were 5 different twists at the end & i had my jaw on the floor at all of them . literally obsessed with this book . the writing was beautifully done 🫶🏼 this is my first book by Keri & i will now be ordering more from her immediately🖤 this book is definitely in my top reads of the year! as always check your TW 🤍

4 star read - dark gothic romance
Format: Kindle
Master of Salt and Bones by Keri Lake 4 STAR READ “You’re my curse. Staying away from you, is like trying to hold my breath when the tide is rising.” This book reminds me a lot of Nightshade, also by Keri Lake, but without the fantasy element. It gives off the same gothic vibes, including flash backs, history of abuse, and sexual deviances. It also has some overlap with the older male character obsession that is seen in Nocticadia - though Lucien doesn’t hold a candle to Professor Bramwell. SUMMARY Lucien was abused, lied to, and manipulated his whole life, by everyone who should have protected and cared for him. A wealthy heir to a massive fortune, he is hard, dark, and delicious. The story unfolds across two timelines, jumping between Lucien’s past and present, and Isa’s POV. Lucien is viewed as the devil of Tempest Cove, covered in scars and rumors abound involving the death of his wife and son. Isa is the daughter of the town whore, who has struggle to fit in and cope with the tribulations of her life. Lucien hires Isa to be his mother’s companion, to keep her company and encourage her to get out of bed each day. As they continue to bump into each other and interact, their relationship develops beyond his dark obsession. Lucien is wary to get attached as his connection to a dangerous secret society puts everyone he cares about at risk, however there may be no way around Isa’s involvement. WHAT I LIKED and DISLIKED It was a great story full of tragedy and resilience. Both characters have deep back stories that unfold throughout the book, we get information at just the right time to make things make sense. It is really well told. It does feel a bit slow in the middle, I took a mid book break to read something else but came back to it and wondered why I stopped - the reason I gave 4 stars was because I had the need to take the break. Which tells me I lost interest during part of it. Lucien has so many layers and each one is full of sadness and devastation. Isa’s story is tragic in its own way, however her youth has her dealing with them in a difference way - she is definitely more detached in her own way. There is an age gap - Lucien is 33, Isa is 19 — I’m not usually a fan of this kind of age gap, but Isa isn’t childish or immature so it works. The book definitely gives Grumpy x sunshine vibes. The spice is well done and paced well throughout the book. If you like spicy, gothic, dark romance and have enjoyed other books by Keri Lake this book will not disappoint. There are references to rape, sexual abuse, physical abuse, and mental illness — I would check any triggers before reading

Great start
Format: Kindle
I loved this book! It's funny but still deals with tough themes, like chronic illness, a serial killer on the loose, and a dash of self-harm. The guys are interesting and distinct, we don't know too much about them yet. It does end on a really terrible cliffhanger but on the bright side the next book is out and I believe the series is complete. I have enjoyed both of these authors separately and this is a great team up!
