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.

3 Alpha Cowboys, One Omega City Girl, 3 Months of Forced Proximity - ALL The Spice
Format: Kindle
What could be better than a Cowboy Romance? How about THREE cowboys. If that Reverse Harem reveal doesn't peak your interest, what if I told you that all the cowboys are also Alphas & our FMC is an Omega? Interested yet? Thought so.... Finding out that there is an entire sub-genre (sub-sub-genre??) of non-shifter Alphas & Omega books has been a recent discovery that I am quite enjoying. Up until this last month I had only seen the Alpha / Omega trope in association with Paranormal Shifter Romance. However, this new-to-me concept introduces all the fun of Alpha & Omega pheromones, heat cycles, & knotting with no were-creature trope required. None of that unnecessary slobber or shedding found here! OK there was some shedding, but that was just from the three adorable adopted cats featured in this story. Oh, and maybe some drool on my end as I through some of the spicier scenes. The spice in this one is hotter'n a blister bug in a pepper patch -- or some other Cash approved country saying. Speaking of Cash...I'm pretty sure I need to send Harley a Thank You card for writing these spectacular men. Maybe a gift basket? How does one appropriately show gratitude to an author for creating truly exceptional male character. Which is, in fact, what all the Alphas in this book are. They hit all the book boyfriend tropes: 🩷 Cash Winslow: Your typical golden retriever cowboy. He is tall, blonde, and has a joke or "cowboy-ish" for almost any situation. 💕Scent: Fresh sage, strong coffee, old leather. 🩷 Walker Stone: Tall, dark, & broody this Cowboy is the enforcer of the group. He is also a HUGE flirt & say all the right things! 💕Scent: Cedar & Cinnamon 🩷 Ridge Colter: The stoic & reserved ginger has a heart of gold behind the walls he tries to put up. 💕Scent: Honey & Fresh Bread The FMC, Sophia Hollis, has her hands....and other places....full with these three. Fresh out of a very toxic (trigger warning) relationship with her ex-Alpha, she has no idea what it means to be truly cherished as an Omega. When she inherited the Wild Hearts Ranch, she figured she would travel from her home in Chicago to Montana, sell the ranch, and be on her way with enough cash to pay off her debts and start a new life for herself. What she didn't expect was for that inheritance to come with terms. Terms that dictate she live on the ranch for three months before she can sell. Three months.....with three hot Alphas....what could go wrong? "Three months in Montana with three Alphas, a bull named Brutus who has it out for me, and I have no idea if this small town even has a heat clinic. What could possibly go wrong?" - pg. 27 Nothing....absolutely nothing goes wrong...in fact, after reading this book I would say that things went very VERY right for her. Without giving too much away, here are just some of my top highlights & notes from the book: Instant alpha / omega scent recognition. Shirtless Cowboys.....a lot of shirtless cowboys. A guest house with a library & swinging chair. (Sadly no on-page library spice) Ranch / Animal Sanctuary. Alpha sponsored shopping trip. (Yes - Dressing Room Fun Occurred) Junk Measuring (With actual measuring tape) Late Night Stargazing Lord Weasleton of a Grandson (Seriously....somebody take this guy out back) Bull Riding & Rodeo (because....of course) Omega Heat Guard Dog Bull (Seriously his name is Bruno & he is very cranky) Adventures with Ice Cream (Mango might just be my new favorite flavor) Smutty Bookclub (That I wish I could join....seriously...the themed meetings...the costumes...LMFAO) Small Town Found Family.....and gossip Cowboy-isms Version of Truth or Dare He makes her "O" 7 times just to compete with the MMC in her bookclub book. And so much more.... For those of you wondering, the true spice starts around 50% in, but the flirting & banter builds the tension in the best of ways. If you are looking for your next Alpha / Omega Cowboys Romance I suggest you take this one for a ride.

Sweet But With Depth!
Format: Kindle
“maybe, just maybe, some things are worth chasing across the sky. Even if you never catch them.” This is a sweet, cozy OV romance—but it actually has unexpected depth. I picked this up expecting a light read with low angst. And, while I got a low angst read—it was so much more than that. It’s people piecing themselves back together after serious hurts, and learning it’s okay to be vulnerable. Learning it’s okay to allow yourself to be loved The characters are well rounded and very real, including the “broody” cowboy that could have easily been a stereotype—but was actually one of the best in the whole book. It’s got just the right level of spice, and boy is it well written! I couldn’t put it down. This is no shallow OV read, this has heart and soul. It’s absolutely beautifully written. It honestly deserves more than five stars!

read it for the cowboys
Format: Kindle
it was a fun, engaging read. there was a lot of time spent on emphasizing how hot these cowboys were ...so that was pretty enjoyable. i love a soft (but hard when you need to be) man -- and these guys were all pillow-soft but also, touch her and die vibes. plus, heats & alpha/omega & knotting - i am in, like flynn! i didn't quite enjoy the influencer/blogger bits but that's a personal preference - but otherwise, it was a cute story that i would recommend.
