Crystals have fascinated scientists and researchers for centuries, with their unique and beautiful structures and properties. Over time, new breakthroughs have been made in the field of crystallography, leading to a greater understanding of how crystals form and interact with their surroundings. In recent years, there have been several exciting discoveries in the world of crystal properties, with implications for everything from medicine to technology.
Crystals have long been known for their beauty and healing properties. However, recent scientific breakthroughs have revealed that crystals possess even more powers than previously imagined. From energy storage to water harvesting, crystals are now being harnessed for a wide range of applications that could transform the way we live.
One of the most exciting breakthroughs in crystal properties is the discovery of piezoelectricity. This is the ability of certain crystals, such as quartz, to generate an electrical charge when subjected to pressure or mechanical stress. This property has made it possible to create devices that can convert mechanical energy into electrical energy, such as watches and lighters. Scientists are now exploring the use of piezoelectric crystals in larger-scale applications, such as generating energy from the movement of vehicles or even human footsteps.
Another promising application of crystals is in energy storage. Researchers have found that certain crystals, such as lithium-ion crystals, have a high energy density, making them ideal for use in batteries. This could lead to the development of more efficient and longer-lasting batteries for use in electric vehicles and other energy-intensive applications.
Crystals are also being utilized in the field of medicine. In recent years, researchers have discovered that certain crystals possess antimicrobial properties, making them effective at killing bacteria and viruses. For example, silver crystals have been found to be effective at killing E. coli and other harmful bacteria. Other crystals, such as quartz and amethyst, are believed to possess healing properties, helping to reduce stress and promote relaxation.
Perhaps one of the most exciting breakthroughs in crystal properties is their ability to harvest water from naturally occurring sources such as fog and dew. Researchers at NYU Abu Dhabi have reported a novel method of harvesting water from fog and dew by observing the process of water spontaneously condensing from its vapor to liquid form and moving across the surface of a slowly subliming organic crystal. This could be a game-changer in the fight against global water scarcity, particularly in desert environments.
New Scientific Breakthroughs in Crystal Properties
In the study, Research Scientist Patrick Commins and Post-doctoral Associate Marieh B. Al-Handawi observed for the first time the process of water spontaneously condensing from its vapor to liquid form and moving across the surface of a slowly subliming organic crystal. This was found to be caused by changes in the width of small channels that appear on the surface of the crystal over time, which guide the condensed water across the crystal’s surface.
In the paper titled “Autonomous and Directional Flow of Water and Transport of Particles across a Subliming Dynamic Crystal Surface” published in the journal Nature Chemistry, researchers describe the process of condensation and movement of water that carries particles on the surface of crystals of hexachlorobenzene, a compound that is often used as a fungicide. Due to sublimation, the surface of this material has a rigid topography with defined parallel channels. Small solid particles such as dust or even metallic nanoparticles were observed to move autonomously along the channels. The motion of these particles was found to be caused by the condensed aerial water, which migrates through the channels due to the change in the cross-section and width of the channels over time.

Organic crystals are made up of organic molecules, which are molecules that contain carbon atoms bonded to other elements such as hydrogen, oxygen, or nitrogen. These molecules can be arranged in a variety of ways to form crystals, which can have a range of properties depending on their structure. One of the most exciting properties of organic crystals is their ability to conduct electricity, which makes them useful for applications such as light-emitting diodes (LEDs), solar cells, and transistors.
In addition to their electrical properties, organic crystals also have unique optical properties that make them well-suited for use in photonics. Photonics is the study of the properties and applications of light, and it encompasses everything from fiber optics to lasers. Organic crystals have the ability to emit and absorb light at specific wavelengths, which makes them useful for a variety of photonics applications. For example, organic crystals can be used to create lasers that emit light in the visible or infrared regions of the spectrum.
Another area of research in crystal properties is the development of new materials for use in medicine. Crystals have long been used in medicine for their ability to act as drug delivery vehicles, but recent breakthroughs have expanded the range of applications for crystal-based medicines. One promising area is the use of metal-organic frameworks (MOFs), which are crystalline materials made up of metal ions and organic ligands. MOFs have a highly porous structure, which allows them to absorb and release gases and other molecules.
MOFs are being investigated for a range of medical applications, including drug delivery, imaging, and tissue engineering. One promising application is the use of MOFs to deliver drugs to specific cells or tissues in the body. MOFs can be designed to target specific cells or tissues, and their highly porous structure allows them to carry a large amount of drug molecules. This targeted drug delivery approach has the potential to greatly increase the effectiveness of drugs while minimizing side effects.
Another area of research in crystal properties is the study of their mechanical properties. Crystals have long been known for their hardness and durability, but recent research has shown that they also have some surprising mechanical properties. For example, some crystals have been shown to be able to bend without breaking, while others can stretch like rubber. These properties are of interest for a range of applications, including the development of new materials for use in engineering and construction.
One example of a crystal with unique mechanical properties is silicon nanowires. Silicon nanowires are extremely thin wires made up of silicon atoms, and they have been shown to be able to bend and twist without breaking. This makes them useful for applications such as sensors and microelectromechanical systems (MEMS), which require flexible materials. Silicon nanowires are also being investigated for use in energy storage devices, such as batteries and supercapacitors.
Applications of Crystals in Water Harvesting
The unique properties of crystals make them ideal for use in various applications, including water harvesting. While the use of crystals in water harvesting is still in the experimental stages, there are promising results that have been achieved. The following are some of the applications of crystals in water harvesting:
- Humidity Harvesting
Humidity is one of the most abundant sources of water in the atmosphere, especially in humid regions. Researchers have been working on developing materials that can collect water from the atmosphere. One such material is zeolites, a type of crystalline aluminosilicates that can absorb water vapor from the air. Zeolites have a honeycomb-like structure that can trap water molecules in the air. Researchers are exploring the potential of zeolites in collecting water in arid regions where the humidity is relatively high.
- Desalination
Desalination is the process of removing salt and other minerals from seawater to make it potable. This process is energy-intensive and expensive, making it inaccessible to most communities in arid regions. Researchers have been working on developing materials that can desalinate seawater using minimal energy. One such material is graphene oxide, a crystalline material that can selectively remove salt ions from seawater. Graphene oxide has a large surface area that can trap salt ions and prevent them from passing through.
- Rainwater Harvesting
Rainwater harvesting is the process of collecting rainwater from rooftops and other surfaces for later use. The collected water can be used for irrigation, washing, and other non-potable uses. Researchers have been working on developing materials that can enhance rainwater harvesting. One such material is titanium dioxide, a crystalline material that can break down pollutants in rainwater. Titanium dioxide can be applied to rooftops and other surfaces to enhance rainwater quality.
The scarcity of water in many regions of the world is a significant problem that needs urgent attention. Scientists and researchers are working on developing new technologies and materials that can help to address this problem. The recent breakthrough in harvesting water using organic crystals is a significant step towards mitigating water scarcity in arid regions. The unique properties of crystals make them ideal for use in water harvesting applications, including humidity harvesting, desalination, and rainwater harvesting. While the use of crystals in water harvesting is still in the experimental stages, the promising results achieved so far provide hope for a future where water scarcity will be a thing of the past.
In addition to these practical applications, crystals also hold significant cultural and spiritual significance for many people. Crystals have been used for thousands of years in various spiritual and healing practices, and their use continues to grow in popularity today. From crystal healing to meditation, people are turning to crystals for their perceived healing and energizing properties.
In conclusion, the ancient powers of crystals are being unlocked through new scientific breakthroughs, leading to exciting new applications in energy storage, medicine, and water harvesting. Whether you believe in their spiritual properties or not, it’s clear that crystals have the potential to change the world in a very real and practical way.
