In sodium batteries, sodium-ions, rather than lithium-ions, travel back and forth between the battery’s anode and cathode to produce electricity. Sodium batteries are not able to hold as much energy, but their low cost makes them attractive for mid- to large-scale energy storage systems, such as for storing energy from solar power or wind farms. Manufacturers are also looking for ways to manufacture both lithium and sodium-ion batteries with only one type of anode material.

Using tin oxide in a battery’s anode gives it the potential to store almost three times the energy of graphite that is typically used in batteries, and it’s easy to make. However, tin oxide wears out quickly and stops working. In their study, the researchers were able to solve the degradation problem by making ultrafine nanocrystals of tin dioxide that were tightly bound to a three-dimensional graphene structure. Their hybrid structure was reportedly robust, well connected and porous, allowing for better transport of electrons and ions.

Their research shows that the material greatly improved the charging capacity and rate of both types of batteries, and the hybrid material “exhibited outstanding electrochemical performance,” according to the team. The researchers also tested the materials in a full battery.

The researchers also worked with scientists at the Department of Energy’s Pacific Northwest National Laboratory, who provided expertise on cathode materials. The research was funded by Washington State University.

Globally, 2.3 billion people live without basic sanitation services and in developing countries, only 27% of people have adequate handwashing facilities at home, according to UNICEF. Not being able to use these facilities makes it harder for women and young girls to manage their periods safely and with dignity.
Poor menstrual hygiene can cause physical health risks and has been linked to reproductive and urinary tract infections, according to UNICEF. It also stops women from reaching their full potential when they miss out on opportunities crucial to their growth. Young girls who do not receive an education are more likely to enter child marriages and experience an early pregnancy, malnourishment, domestic violence, and pregnancy complications as a result. Period shame has negative mental effects as well. It disempowers women, causing them to feel embarrassed about a normal biological process.

In 2018 alone, people in the U.S. bought 5.8 billion tampons, and over the course of a lifetime, a single menstruator will use somewhere between 5 and 15 thousand pads and tampons, the vast majority of which will wind up in landfills as plastic waste.
The most common menstrual products are a veritable cornucopia of plastic. Tampons come wrapped in plastic, encased in plastic applicators, with plastic strings dangling from one end, and many even include a thin layer of plastic in the absorbent part. Pads generally incorporate even more plastic, from the leak-proof base to the synthetics that soak up fluid to the packaging.

For Ann Borowski, who researched the ecological impact of sanitary products, the sheer numbers were astounding.
“I don’t want to contribute 40 years of garbage to a landfill just to manage something that shouldn’t even be seen as a problem” she says. “It seems like something we should have a little more control of by now. I don’t want to have that kind of burden on the planet”.

Our Graphene enhanced sanitary products posses three prime characteristics:

• They are Eco-friendly as start decomposing within six months of them being disposed.
• The Graphene used in the manufacturing of the Sanitary Pads have deodorising and antibacterial properties.                                                    
• They are healthy and safe as no chemicals, bleaches or perfumes are used in the manufacturing process.

They are Breathable The conventional sanitary pads tend to restrict the free flow of air while trapping the dampness and heat and promoting the growth of bacterial and fungal infections. However, with the breathable layers that are possible only with the inclusion of graphene oxide that we produce. With the newest techniques of making use of graphene in sanitary products, they become breathable and deter the growth of forms of fungal and bacterial infections.
They have extreme absorbing ability and are able to absorb three times that of conventional sanitary pads. The sufficient supply of hydrogen in the pads can hold up the penetrated water instead of allowing them to back-flow or leak sideways. Our graphene infused sanitary pads has 360-degree wrapping technology that has leak-proof and edge-lock abilities.

Graphene is the thinnest yet the most robust nano-material that can be used in sanitary products. Graphene enhanced sanitary pads have the ability to absorb 5 times more fluid traditional pads. We makes the bottom layer of the sanitary pads breathable allowing the free-flow of air
 to activate the blood flow.

Our  products contain no harmful chemicals, toxins, bleaches or perfumes.

Standard sanitation products usually consist of acetone, heavy metals, formaldehyde, dioxin, and many more chemicals. These substances tend to cause allergies and irritation to the skin, and with prolonged exposure, they may lead to some of the severe health issues. Also, these products are believed to contain carcinogens and harmful hormone disrupters.

Graphene Oxide Strip: The excellent combination of the naturally found element like the graphene oxide along with the hydrogel lining on the sanitary pads is known to reduce the odour or the growth of bacteria as well. They also tend to help with the menstrual cramps as well.
 Unpleasant odour and does not provide any protection from bacteria: The protection fragrances in the regular pads tend to cause irritation of the skin and allergies as well. The damp and warm environment created in the pad promotes fungal and bacterial infection as well.

BENEFITS of our graphene enhanced sanitary products:                       

• Reduces the abdominal cramps during menstruation
• Can absorb 5 times more fluid than traditional pads.
• Possesses anti-cancer effects      
• Contains no harmful chemicals, toxins, bleaches, and perfumes
• Thinnest nano-material that can be used in sanitary products
• Can be washed and reused more than 20 times.
• Eco-friendly as start decomposing within six months of them being disposed
• Eliminates allergies and infections.

In order to curb the global effects of alcohol impaired driving our research & development team have developed and patented  an innovative Vehicle Alcohol Sensor Device. The sensor detects the attentiveness of alcohol l gas in the air and an analog voltage is an output reading. The sensor can activate at temperatures ranging from -10 to 50° C

How does Alcohol Sensor work?

Before the driver takes the vehicle to the road, he/she needs to blow on the device’s graphene sensor. If the device detects alcohol content above the prescribed limit set by the Motor Vehicle Act, the vehicle’s engine will fail to start.

Can the device be bypassed?

Bypassing the sensor is very difficult. If any person other than the driver  attempts to blow on the graphene sensor, it will activate an infrared feature in the device, halting the vechicle starting process altogether.

The sensor device also features a passenger alert system which detects the driver’s eye movements indicating that the driver is feeling drowsy or intoxicated.

The device is equipped with:

GPRS-GSM
Biometric Technologies
Automated SOS call

In 2015, world leaders agreed to adopt the Sustainable Development Goals (SDGs), in order to eradicate poverty, protect the planet and ensure prosperity for all by 2030. These goals apply to all countries and cover several sectors, such as climate change or gender inequalities. The number 6 is dedicated to water: Clean water and sanitation for all.Because of its cross-sectional dimension, water is essential for achieving other goals, such as Zero Hunger, Health and Wellness. Unfortunately, at the current rate of progress. it seems that many countries will not be able to reach the sixth goal by 2030.

Greater efforts and greater investments are necessary to achieve all the objectives, in particular with regard to health and hygiene: national policy adjustments, resource mobilization, national statistical systems are needed to monitor the new SDG indicators, among other things. But the important thing is to provide clean water to everyone on this earth through advanced solutions. This is possible due to the use of Graphene filters because of their high capability.

Lack of access to water

Nearly 700 million people in the world do not have access to drinking water. Drinking dirty water has disastrous consequences on the health and nutrition of people, greatly weakening the body. People who drink contaminated water can quickly become malnourished. In fact, 50 percent of cases of child malnutrition is caused by repeated diarrhea and intestinal infections due to dirty water and/or inadequate hygiene.

Despite undeniable progress since 1990, made by governments, NGOs with the support of the United Nations, more than 2 billion people currently do not have access to drinking water. Ninety percent of these people live mainly in rural or remote areas, but the problem would soon be unprecedented, according to climate experts.

Use of Graphene in Water Filtration

Water is an invaluable resource and the intelligent use and maintenance of water supplies is one of the most important and crucial challenges that stand before mankind. New technologies are constantly being sought to lower the cost and footprint of processes that make use of water resources, as potable water (as well as water for agriculture and industry) are always in desperate demand. Much research is focused on graphene for different water treatment uses, and nanotechnology also has great potential for elimination of bacteria and other contaminants.

Among graphene’s host of remarkable traits, its hydrophobia is probably one of the traits most useful for water treatment. Graphene naturally repels water, but when narrow pores are made in it, rapid water permeation is allowed. This sparked ideas regarding the use of graphene for water filtration and desalination, especially once the technology for making these micro-pores has been achieved. Graphene sheets (perforated with miniature holes) are studied as a method of water filtration, because they are able to let water molecules pass but block the passage of contaminants and substances. Graphene’s small weight and size can contribute to making a lightweight, energy-efficient and environmentally friendly generation of water filters and desalinators.

It has been discovered that thin membranes made from graphene oxide are impermeable to all gases and vapors, besides water, and further research revealed that an accurate mesh can be made to allow ultrafast separation of atomic species that are very similar in size – enabling super-efficient filtering. This opens the door to the possibility of using seawater as a drinking water resource, in a fast and relatively simple way. When the membrane is prepared using these methods, the energy consumed is lower, the operation is simple, the thickness of the Graphene Oxide membrane remains even, the level of flexibility remains intact, and it’s easy to transfer the membrane to other substrates.

RINZTECH patented water filtration technology

RINZTECH patented water filtration technology is a cost effective solution for the many millions in the world who do not have access to clean drinking water. The technology includes Graphene Oxide, Neem, Bamboo and Activated carbon.

The simple prototype demonstrates our multilayer water filter removing impurities from coca cola. The filter can remove more than 200 impurities.

Graphene’s myriad of exceptional qualities can open the door to many interesting types of paints and coatings. Graphene’s high resistivity can make for durable coatings that do not crack and are resistant to water and oil, its excellent electrical and thermal conductivity can be used to make various conductive paints, and a strong barrier effect can contribute to extraordinary anti-oxidant, scratch-resistant and anti-UVA paints.

Graphene enables a wide array of functional paints, for many possible applications. Among these can be high performance adhesives enabled by graphene’s high adhesion property, anti-bacterial coatings, solar paints (capable of absorbing solar energy and transmitting it), paints that provide isolation for houses, anti-rust coatings, anti-fog paints and UV ray blockers, non-stick coatings for various domestic applications (like frying pans and countertops) and even a much-hyped possibility (currently under scientific examination) of a coating that turns a regular wall into a screen.

Graphene added to the manufacture of paints, coatings, and other building materials enhances the hardness, durability, compression, and tensile strength, to name a few. It also reduces the weight of materials, while being 200 times stronger than steel.

The addition of graphene also increases the coverage of the paint. With one litre, you can paint two 8m2 coats of paint, according to the press release, which reduces the amount of labour and paint needed.

As graphene is a conductive material (1000 times more so than copper), the paint improves the thermal regulation of buildings, saving energy by requiring less heating and air conditioning.

Magneto-rheological fluid (MRF) is a type of smart material whose rheological properties (e.g. Viscosity) can be rapidly varied by applying a magnetic field. It is a free-flowing liquid state in the absence of a magnetic field while its viscosity increases on application of magnetic field. MRF can be controlled  (increased or decreased) with the strength of the magnetic field. The MR Fluid shifts from solid to the liquid state and the other way round quite quickly. Thus, it helps in making the buildings flexible, which allows them to adapt with any of the external forces.

Components of Magneto-rheological Fluids:

Magneto-rheological Fluid is processed by making use of three prime ingredients:

• the carbonyl iron particles that are also known as the ‘soft’ particles of iron that have a diameter of 3-5 micrometres
• additives to enhance the viscosity and fluidity of the material, helps the particles to remain suspended in liquid, which also helps in reduction of the pace of gravitational settling of the particles of iron
• Also, we make use of hydrocarbon oil as a carrier liquid for producing the MR Fluid.

Application of the MR Fluids:

The MR Fluids can be used in various industries, which involve:

• Automotive Industry
• For the seismic protection of the buildings
• It is used in the washing machines
• MR Fluid is used in medical science for manufacturing of the prosthetic knee
• For the preparation of Artificial Muscles
• For polishing the devices
• Used in Clutches and Brakes
• Used in hydraulic valves
• MR Fluid is now being used as Robot Blood

Why is Magnetorheological Fluid in demand?

MR Fluid is a whole new sensation in the market and has made a remarkable mark in the industry. The experts suggest that the demand for MR Fluid will grow exponentially in the upcoming future.

The demand for MR Fluid is increasing for robotics, which is being used in the braking and damping systems. Smart fluid as it sometimes called is used in the fields of automotive, engineering, medicine and construction. Magneto rheological (MR) fluid technology has been proven for many industrial applications like shock absorbers, hydraulic systems, actuators, etc.

Graphene oxide is a unique material that is a single monomolecular layer of graphite with various oxygen containing functionalities such as epoxide, carbonyl, carboxyl and hydroxyl groups.

When the electrically insulating graphene oxide is reduced it resembles graphene but contains residual oxygen and other heteroatoms as well as structural defects. This form is called reduced graphene oxide rGO.

Graphene oxide and reduced graphene oxide can be used in electronic devices, nanocomposite materials, polymer composite materials, energy storage, biomedical applications and catalysis. When we compare graphene oxide and reduced graphene oxide we can see some differences between them. The advantage of reduced graphene oxide has over graphene is that it can be stored longer without agglomeration. Reduced graphene oxide is more stable in organic solvents. Also reduced graphene oxide is conductive whereas graphene oxide is not conductive and isn’t as strong.

Reduced graphene oxides has an important role in electronics. Reduced graphene oxide can be used in light emitting diodes and solar cell devices. For both of these materials visible light transparent electrodes are so important. Using reduced graphene oxide as a transparent electrode is a convenient alternative to other transparent electrodes for these devices. In addition to being a transparent electrode, reduced graphene oxide has been used as a hole transport layer in polymer solar cells and LEDs.

When we look at the other application areas of reduced graphene oxide we can see it can be used as high capacity energy storage in lithium ion batteries. In these applications, electrically insulating metal oxide nanoparticles/nanopowder are adsorbed onto reduced graphene oxide to increase the performance of these materials in batteries. So it can be said that the high surface area reduced graphene oxide is useful as an energy storage material in supercapacitors.

Reduced graphene oxides can also be used in biosensors. In many researches reduced graphene oxide have been used as components in several systems designed to detect biologically relevant molecules.

Graphene was first observed in electron microscopes in 1962 supported on metal surfaces. It was rediscovered in 2004 by Novoselov and Geim. They were awarded the Nobel Prize in Physics 2010 “for groundbreaking experiments regarding the two-dimensional material graphene”. Since 2010, graphene has attracted a growing interest for many applications.

Graphene comprises carbon atoms that are bonded together in hexagonal patterns. Mono-layered and double-layered graphene is so thin that it can be considered a two-dimensional material. Graphene’s flat honeycomb pattern gives it many amazing characteristics. It is one of the strongest, lightest, most conductive, and transparent materials. The single layers of carbon atoms provide the basis for many other materials. Graphene oxide (GO) is an oxidized graphene derivative, which is less expensive and easier to produce. Graphene cannot be used as a separation membrane being hydrophobic and impermeable to water. The more hydrophilic GO serves as a basis for nano-membranes impermeable to impurities, salts, or bacteria but permeable to water.

Graphene is an amazing conductor of electricity and far superior to any other material currently been used. Graphene conducts electricity better than copper. Graphene can also be used as a thermal conductor or insulator depending on the orientation of the graphene. Imagine a piece of paper made from graphene lying on a table. Graphene in this orientation allows heat to quickly move across it.  Stand the paper upright and the graphene resists heat transfer.

Anything made from graphene would be more lightweight. Cars made from graphene would be able to travel  2-3 times further on the same amount of energy. Clothing could also be made from graphene. They would be very lightweight, breathable, and more resistant to wear and tear.

Batteries could store up to 10 times more energy and charge 5 to 10 times faster. This would allow manufacturers to power larger things like cars, trucks, and even planes. Because graphene can be both transparent or opaque it could become a durable replacement for glass. Graphene is an amazing discovery that has the possibilities to change the future of technological advancements

Graphene’s properties

Graphene is the thinnest material known to man at one atom thick, and also incredibly strong and is about 200 times stronger than steel.
