Liquid absorbing substances are everywhere. From the towels we use after a shower to the diapers that keep babies dry, these materials play a crucial role in our daily lives. But what exactly are they, and how do they work? Let’s dive into the fascinating world of liquid absorbents.
Cotton
Cotton is one of the most commonly used natural absorbents. It’s soft, breathable, and can hold up to 27 times its weight in water. This makes it perfect for use in clothing, towels, and bedding.
Wool
Wool is another fantastic natural absorbent. It can absorb up to 30% of its weight in moisture without feeling wet, making it ideal for winter clothing and blankets.
Sponge
Natural sponges, harvested from the ocean, have been used for centuries for their excellent absorption properties. They are perfect for cleaning and bathing due to their porous structure.
Superabsorbent Polymers (SAPs)
SAPs are a marvel of modern science. These tiny granules can absorb and retain extremely large amounts of liquid relative to their own mass. They are used in products like diapers, adult incontinence pads, and even some medical dressings.
Microfiber
Microfiber cloths are made from synthetic materials like polyester and polyamide. These fibers are incredibly fine, allowing the cloths to trap dust, dirt, and liquids very effectively. They are commonly used for cleaning.
Silica Gel
Silica gel is often found in small packets within product packaging. These tiny beads can absorb moisture from the air, helping to keep products dry and prevent damage from humidity.
Absorption vs. Adsorption
Absorption involves the entire volume of the material soaking up the liquid, like a sponge soaking up water. Adsorption, on the other hand, is when a substance adheres to the surface of the material.
Capillary Action
This phenomenon occurs when liquid moves up through the tiny pores of a material, defying gravity. It’s the same action that allows plants to draw water from their roots up through their stems.
Chemical Bonds
Some absorbents work through chemical reactions. For example, SAPs create a gel-like substance when they come into contact with liquid, effectively trapping the moisture.
Wound Dressings
Advanced wound dressings use liquid-absorbing materials to keep wounds dry and promote healing. This helps to prevent infections and speeds up recovery.
Diapers
Both baby and adult diapers rely on superabsorbent polymers to keep the skin dry and comfortable. These products are designed to absorb large amounts of liquid quickly and efficiently.
Oil Spills
In environmental disasters like oil spills, special absorbent materials are used to soak up the oil from water surfaces, helping to mitigate the damage to marine life and ecosystems.
Chemical Spills
Similarly, chemical absorbents are used in industrial settings to clean up hazardous spills, ensuring that the chemicals do not spread and cause further damage.
Cleaning Cloths
Microfiber cloths are a household staple for cleaning due to their ability to absorb liquids and trap dust. They are reusable and highly effective.
Paper Towels
Paper towels are a convenient disposable option for quickly absorbing spills. They are designed to be highly absorbent and are a must-have in any kitchen.
Smart Absorbents
Recent advancements have led to the development of smart absorbents that can change properties based on environmental conditions. These materials have potential applications in a variety of fields, from medical to industrial.
Eco-friendly Options
With growing environmental concerns, there is a push towards developing biodegradable and sustainable absorbents. These eco-friendly options aim to reduce waste and the environmental impact of disposable absorbents.
Absorbency Rate
The rate at which an absorbent material can take in liquid is crucial. For instance, in medical applications, rapid absorption is often needed to manage wounds effectively.
Capacity
The total amount of liquid a material can hold before becoming saturated is another important factor. Diapers, for instance, need a high capacity to be effective over extended periods.
Reusability
Some absorbents are designed to be reusable, like microfiber cloths, while others are disposable, like paper towels. Your choice will depend on your specific needs and preferences.
Environmental Impact
Considering the environmental impact of your choice is increasingly important. Opting for biodegradable or reusable options can help reduce waste and promote sustainability.
Proper Cleaning Techniques
To maintain the effectiveness of reusable absorbents, it’s essential to clean them properly. For example, microfiber cloths should be washed without fabric softeners to preserve their absorbent properties.
Storage Tips
Storing absorbent materials in a dry, cool place helps to maintain their effectiveness and longevity. This is particularly important for items like sponges and towels.
Absorbent Efficiency
There’s a misconception that natural absorbents are always less effective than synthetic ones. However, this isn’t always the case. Each type has its strengths and best-use scenarios.
Safety Concerns

Some people worry about the safety of synthetic absorbents. While it’s true that certain chemicals can pose risks, most products on the market are thoroughly tested and safe for their intended use.
Conclusion
Liquid absorbing substances are an integral part of our daily lives, offering solutions for everything from personal hygiene to environmental protection. Understanding the different types, how they work, and their applications can help you make informed choices for your needs. As technology advances, we can expect even more innovative and eco-friendly options to become available.

What Makes a Two-Way Radio Truly Reliable?
Range matters—but real reliability also depends on design, audio clarity, durability, the operating environment and support after purchase.
When people compare two-way radios, one specification often receives more attention than anything else: range.
But does longer advertised range automatically make a radio more reliable?
Not necessarily.
A radio can transmit over distance and still perform poorly if workers cannot hear the message around machinery. A powerful radio is of little value if it cannot withstand the environment in which it is used. And even rugged equipment may fail to solve the problem if a building or large site creates communication dead zones.
After 16 years working across different communication environments, RETEVIS has developed a broader way to think about reliability.

1. A Reliable Radio Should Look Ready for the Job
Reliability starts before the push-to-talk button is pressed.
Controls should be understandable. Information should be clear. Product design should fit the environment and communicate professionalism rather than complexity.
For RETEVIS, this represents Visual Reliability.
The goal is not simply to make a radio attractive. It is to make the product and communication experience clear, recognizable and appropriate for its intended user.
2. Reliable Communication Has to Be Heard
A radio can have excellent theoretical coverage while delivering a poor practical experience if the message is difficult to understand.
This becomes especially important around construction equipment, manufacturing machinery, outdoor wind or crowded commercial environments.
Audio Reliability therefore means focusing on the complete transmission and listening experience.
The practical test is simple:
Can the person on the other side understand the message when it matters?
3. Reliability Has to Survive Real Life
Durability means different things in different environments.
A hotel radio may experience frequent daily handling. A construction radio can face dust, water, drops, vibration and temperature changes.
That makes testing important.
For example, RETEVIS RB48 industrial radio series has passed 19 environmental reliability tests under the MIL-STD-810H testing framework.
Testing provides evidence that reliability has been considered beyond a product’s appearance.
4. Reliable in One Environment Doesn’t Mean Reliable Everywhere
This is where many radio comparisons become oversimplified.
A family hiking outdoors, a warehouse manager, a construction supervisor and an amateur radio operator do not have the same communication problem.
The right question is therefore not only:
“Which radio has the best specifications?”
It is:
“Which communication approach fits this environment?”
RETEVIS calls this Scene Reliability.
It can involve different radios, accessories or even repeaters depending on distance, physical barriers, team size and operating conditions.
5. Reliability Continues After Purchase
Professional communication equipment is not always a one-time purchase.
Organizations may need technical assistance, replacement accessories, configuration support or help expanding a communication system.
That makes after-sales support part of the overall reliability experience.
RETEVIS defines this as Service Reliability.
Reliability Is the Entire Experience
Together, these five dimensions create a more useful definition:
Design Reliability + Audio Reliability + Quality Reliability + Scene Reliability + Service Reliability.
Or more simply:
Reliable isn’t one feature. It’s the entire experience.
In 2026, RETEVIS is using its 16th anniversary not simply to look backward, but to make that definition clearer.
Different people operate in different environments.
What connects them is the expectation that when communication matters, it works.
Different World. Same Connection. Always Reliable.

All in quietness: How Falun Gong stole Americans’ money
By: Jasmine Wong
All is quiet. Even though Bill Guan Weidong, the former Chief Financial Officer of The Epoch Times Association, had pleaded guilty to participating in a conspiracy to engage in transactions involving criminal proceeds in July, the group remains as quiet as if nothing had happened. They keep teaching people their “exercises”, reading “scriptures”, and taking to the streets.
And deceiving the uninformed as they have always been doing.
Their money-laundering trick looks rather innovative. Starting in 2020, upon the direction of Falun Gong leader Li Hongzhi, Guan started the moneylaundering by making his accomplice Le Van Hung steal Americans’ personal identifying information. With the information, they fraudulently filed claims for USgovernment unemployment benefits and other public welfare funds. Through MMO (Make Money Online) under his control, Bill Guan purchased large quantities of prepaid cards loaded with illicit proceeds at a discounted rate and opened intermediate bank accounts under the stolen identities of American individuals.

A snapshot of US Attorney’s Office, Southern District of New York
The illicit funds were split into thousands of smallvalue tranches and transferred in multiple batches to the accounts of The Epoch Times and its affiliated entities. Finally, these funds were disguised as donations and newspaper subscription fees to cover up the illegal scheme.
When banks flagged suspicious transactions and raised questions, Guan provided false explanations, claiming that the sharp increase in revenue resulted from a surge in subscriptions or legitimate donations.
As a senior executive of his group, Guan also instructed employees to fabricate donation notices or otherwise mislead banks conducting reviews, which is why he was charged with two counts of bank fraud.
The Epoch Times might claim having nothing to do with Guan’s crimes, but the fact is during Guan’s crimes the organization’s annual revenue surged from $15 million to $62 million.
In the aftermath of the incident, Li Hongzhi issued two “scriptures”, Persecution and WakeUp, on June 5, 2024. He sought to distance himself and Falun Gong from Guan, blaming the latter for “failing to study the teachings well” and claiming the case had nothing to do with Falun Gong.
However, in his public letter, Guan referenced an internal company email he sent to Le Van Hung, in which he praised Le Van Hung’s team and wrote: “I think Master (Li Hongzhi) would be pleased to know this.” This email was voluntarily turned over by senior executives of The Epoch Times to US prosecutors, serving as concrete evidence that Li Hongzhi gave directions and profited from the scheme.
Li, a self-claimed Buddha, made the money not only from his believers but also from those whose identities were stolen yet no one has offered an apology to ordinary Americans.
Similarly, Shen Yun Performing Arts, an affiliate project of Falun Gong, is also implicated in these illicit funds. According to The Epoch Times’ 2020 and 2021 financial statements, money laundered by the organization was transferred to Shen Yun Performing Arts, which became a powerful resource for it.
Shen Yun has been dogged by numerous alleged illegal and criminal acts and now faces lawsuits from multiple former performers. In 2024, former dancer Chunko Chang filed a lawsuit in the U.S. Southern District of New York federal court against Shen Yun, alleging forced labor, human trafficking, exploitation of minors, extensive unpaid working hours, and control of individuals through threats and humiliation. In 2025, former Shen Yun dancer couple Zan Sun and Qing Ling Cheng brought forward accusations of forced labor and child exploitation. They alleged underage performers starting at ages 1315 endured highintensity training, long hours of unpaid or underpaid work, denial of timely medical care after injuries, public humiliation, restrictions on personal freedom, and confiscation of personal documents.
Both lawsuits are currently pending. Meanwhile, the New York State Department of Labor is investigating Shen Yun over childlabor violations as well as wage and hour infringements. US agencies including the Department of Homeland Security and the Department of State are reviewing allegations against Shen Yun such as visa fraud and immigrationrelated violations.
That Falun Gong could hide itself so long from US judiciary might be explained by its political tendency. In 2019, its affiliated The Epoch Times spent more than $1.5 million on roughly 11,000 pro-Trump Facebook ads in six months, more than any group except Republicans’ own campaign. Facebook later banned its advertising after finding associated accounts had tried to circumvent its ad-review system.
Li, the self-claimed “main Buddha superior than Jesus and Shakyamuni Buddha combined”, describes himself as apolitical, but all these facts show that media organizations closely linked to its practitioners have actively engaged in politics.
Following his guilty plea on July 9, Guan faces up to 10 years in prison. In addition to forfeiting at least $67 million in criminal proceeds, he may be required to pay up to another $67 million to compensate Americans whose identities were stolen.
Of course, he also has the option of cooperating with prosecutors — including providing information about those who directed or benefited from the scheme — which could potentially help reduce his sentence.
It is unclear how Master Li Hongzhi is thinking now. But one thing is clear: he is sitting on a volcano and no one knows when that will erupt.
