Chinese scientists have developed a new strategy for large-scale fabrication of bio-inspired artificial wood that manifests lightweight and high-strength properties with the mechanical strength comparable to that of natural wood.
A study published on Friday in the journal Science Advances described the high-performance polymeric materials with wood-like cellular microstructures.
A research team led by Yu Shuhong from the University of Science and Technology of China (USTC) transformed traditional phenolic resin and melamine resin into the artificial wood-like materials by self-assembly and the thermocuring process, Xinhua reported.
Their strategy provided a new route to fabricate and engineer a wide range of high-performance biomimetic engineering composite materials with desirable multiple functions and advantages over the traditional counterparts, having broad potential applications in many technical fields.
The liquid thermoset resins were firstly “unidirectionally” frozen to prepare a “green body” with the cellular structure, followed by the subsequent thermocuring to get the artificial polymeric woods. They are highly controllable in the pore size and wall thickness.
Starting from aqueous solution, the strategy also represented a green approach to prepare multifunctional artificial woods by compositing various nanomaterials, such as cellulose nanofibers and graphene oxide, according to the study.
Compared with natural woods, the artificial woods have better corrosion resistance to water and acid with no decrease in mechanical properties. They also have better thermal insulation and fire retardancy.
The artificial polymeric woods stand out from other engineering materials such as cellular ceramic materials and aerogels in terms of specific strength and thermal insulation properties.
As a kind of biomimetic engineering materials, this new family of bio-inspired polymeric woods is supposed to replace the natural wood when used in harsh environments, Yu said. (IANS)

South Korean game developer has introduced a new initiative for Battlegrounds Mobile India (BGMI) which will enable a new level of parental control via time limitations and OTP confirmation. The 'Game Responsibly' initiative will also show warning messages along with break reminders, game limits and more. "Every player, below the age of 18, needs to register a parent or a guardian before they start playing for the first time. An OTP will be sent to the registered person's number, post which the minor is allowed to play the game," the company said in a statement.
Some games can get intense and make players lose track of time. However, with timely break-time reminders, the developer has made sure players get the required downtime. These reminders will help them look up from their game and get back to real life, maintaining a healthy game-life balance. In addition, with a strict gameplay limit in place players below 18 years must not indulge in gaming for more than 3 hours per day. This automatically helps them treat gaming as an activity performed in moderation.
The brand has also set an in-game daily spend limit of Rs 7,000 that automatically stops them from overspending and overgaming. Krafton recently announced that it has removed 25 lakh accounts in just over a month to eradicate cheating on Battlegrounds Mobile India (BGMI). Since the last announcement, between October 1 and November 10, Krafton banned 25,19,692 accounts permanently and 7,06,319 temporarily. "The company has cleaned out most of the cheaters in the game, making BGMI a much more fun experience, and will continue to take whatever step is necessary to keep BGMI fair and fun," it claimed.

The rise in air pollution, coupled with lousy lifestyle habits, is causing a spike in respiratory diseases. According to a Lancet report, the contribution of chronic respiratory diseases in India increased from 4.5 per cent in 1990 to 6.4 per cent in 2016. With respiratory issues on the rise, there is an increased demand for natural solutions to treat such issues. Instead of conventional medicine, people are turning to alternative medical therapies to find cures for ailments.
Common Lung Disorders
Bronchitis is a health condition that causes inflammation in the airways of the lungs. This leads to narrowing of the air pathways and excess mucus causes wheezing, coughing and difficulty breathing. It is a chronic condition that interferes seriously with daily life.

Chronic Obstructive Pulmonary Disease (COPD)
It is a chronic inflammatory lung disease that obstructs the airflow to the lungs. Symptoms of COPD include breathing difficulty, mucus (sputum) production, coughing, and wheezing. It can result from long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. Those affected by COPD are at an increased risk of developing lung cancer, heart disease, and a variety of other conditions.

This is another variation of COPD. Bronchitis causes a similar build-up of mucus that can cause inflammation and coughing. The lungs' airways are constantly inflamed as chronic bronchitis often lasts for months on end. Symptoms of chronic bronchitis include incessant coughing, whistling sounds while breathing, wheezing and a tightening of the chest. It is said that the cure for all ailments is available the natural way. Here are some of the alternative medicine approaches to treat respiratory disorders.

Alternative Medicinal Approaches to Treat Respiratory Disorders
Asthma is one of the most common lung diseases. One of the primary causes of asthma is allergies, which often result from the food consumed. It is crucial, therefore, to first prepare a diet that is suitable for an individual. Often, dairy products, meats, and certain nuts can increase the production of mucus. Foods like these must be avoided. Also, antioxidants can prevent damage resulting from chronic obstructive pulmonary disease. Diet is important in this regard, as fruits and vegetables high in Vitamins A, C, and E can improve the condition of COPD patients.

Yoga and Exercise
Treatment of lung disorders often involves the use of the lungs to promote healthy breathing habits. Exercises like cycling, swimming, yoga etc. that create a need for full capacity breathing are of great importance. Exercising the diaphragm is important and simple activities can go a long way in the treatment of the same. Pranayama, the practice of controlled breathing, is an integral part of alternative treatment for people suffering from respiratory issues. This extensive breathing practice helps to expand the lungs and improve the capacity of the lungs, which helps an individual breathe more freely.

It is important to remember that no one complementary or alternative therapy works well for everyone with respiratory issues. Therefore, a proper assessment is done before deciding on the approach to the treatment plan. For those considering alternative medicine for their respiratory problems, it is recommended to speak to an expert first and discuss the approach that may work best.
