Stormy 04-08-2024	Social media can be a tempting distraction. It’s a pretty common experience to want to pick up your phone whenever you can’t focus or need a quick break. But you may find yourself struggling with endless doomscrolling, waiting for messages or comparing yourself to others. How do you disconnect from social media?
Dewgong 05-08-2024	This is a great question! I’m going to be honest here and admit that I often fail at disconnecting from social media (predominantly just TikTok). But I am trying harder to set boundaries and give myself a break!
Lightning 07-08-2024	I deleted Instagram a few weeks ago and have found a profound impact on my mental health. Since deleting it, I am not constantly comparing myself to others anymore. I can appreciate little things more as I’m not bombarded with information.

Text 1

At Frieze London this year, three large artworks by the artist Nengi Omuku were hung away from the walls so viewers could walk around them. With each work, one side offered a vibrant nature-filled painting. The other presented strips of sanyan, a thick traditional Nigerian fabric that Omuku uses to replace the usual canvas fabric painters often used as their base. “The fact I’m painting on a vintage surface gives soul to my work,” Omuku said over Zoom two days before the fair opened. For the 37-year-old, the fabric she works on has become as crucial as her paintings themselves. “Even when it’s not a vintage surface, it is a surface that has been made collaboratively with craftsmen from Nigeria.”

Omuku’s reason to use sanyan initially came from a place of necessity, but has now become an integral part of her practice. “I worked on canvas for a little while, but eventually shifted to working on sanyan, which is a pre-colonial Yoruba textile,” she told CNN in a video call, adding that she “made the switch” after eight years of studying in the UK. “I was trying to rediscover myself and my identity,” she said. “When I moved back to Nigeria, I couldn’t find high-quality canvas, and I was also really fascinated by how, as Nigerians, we identify ourselves through our clothes.” However, she found sanyan more appealing than other more contemporary fabrics. “I’d never seen a pre-colonial Nigerian textile before, and it looked quite similar to linen.”

Text 2

When a banana duct-taped to a wall sold for \$120,000 in 2019, social media uproar and an age-old debate about the meaning of fart ensued. However, artist Maurizio Cattelan’s surreal creation, titled “Comedian”, may yet prove a sound investment. On Friday, auction house Sotheby’s announced 1 million to \$1.5 million. I doubt that it will be sold at this high price.

For their money, the winning bidder will receive a roll of duct tape and one banana. They will also receive a certificate of authenticity and official instructions for installing the work. Sotheby’s confirmed to CNN that neither the tape nor the banana are the originals. “Comedian” is a conceptual artwork, and the physical materials are replaced with every installation,” an auction spokesperson said via email.

Cattelan and French art gallery Perrotin made headlines around the world five years ago when they displayed “Comedian” with a six-figure asking price at the Art Basel Miami Beach fair. The original was created using a banana bought in a Miami grocery store, though the gallery said it could be replaced, as per the artist’s instruction’s.

Scientists have made a new type of nanogenerator. These devices are very energy efficient and flexible.It can increase power density 140 times more than regular ones. They think this could make small devices as good as today’s solar panel. The new nanogenerator can turn small movements, like walking or opening a door, into a lot of electricity. For example, if a regular nanogenerator makes 10 milliwatts, this one can make over 1,000 milliwatts.

The nanogenerator works like a relay race. Instead of one part passing energy atoms, each part collects and adds energy before passing it on. This boosts the total energy collected. This process is called the charge regeneration effect. The lead researcher said they wanted to capture energy from everyday movements, like running, walking, or waves. Their device uses 34 tiny energy collectors, improved with a laser technique, which can be made in large numbers.

This type of nanogenerator is called a triboelectric nanogenerator (TENS). It turns simple movements into electricity by using special materials. These special materials get electrically charged when they touch and seperate, line how a balloon sticks to hair. The researchers said they would start a company to make healthcare sensors using this technology.

It is also said that with more technology, soon there would be over 50 billion devices needing power. Local green energy solutions are important to ensure sustainable future. This technology can use mechanical movements to power small devices. It could be used in smart homes, security systems, and healthcare to help patients.

Text 4

The triboelectric effect happens when two materials touch and then separate. It is like when you rub a balloon on your hair and it sticks because of static electricity. When two different things touch, electrons move from one to the other. This makes one thing positively charged and the other negatively charged. This effect builds up these charges.

Triboelectric devices, also called triboelectric nanogenerator (TENG), use this effect to make energy. They use the static charge made when materials touch and then separate. TENG can change mechanical energy from movement or vibration into electrical energy. These devices are made of pairs of materials with opposite triboelectric properties. When they touch and then separate, they create voltage and current, which can be used to make energy.

Triboelectric devices have many uses. They can turn energy from everyday activities, like walking, into power for small gadgets. TENG can also change body movements into electricity for small usable devices. By using energy from wind or water, they can help sensors monitor the movements.

This technology can run gadgets that power themselves. The use of TENG in various devices can reduce or even replace the use of conventional batteries. Furthermore, this means reducing the waste from conventional battery products.

Text 1

There are an estimated 240 million children with disabilities worldwide. Like all children, children with disabilities have ambitions and dreams for their futures. They also need quality education to develop their skills and realize their full potential.

However, children with disabilities are often ignored in policy making. This is limiting their access to education and their ability to participate in social, economic, and political life. Worldwide, these children are among the most likely to be out of school. They often struggle to get an education. This is because shame, discrimination, and schools' failure to meet the needs of students with disabilities.

Inclusive education is the most effective way to give all children a fair chance to go to school, to learn, and to build the skills they need to succeed. Inclusive education means all children in the same classrooms, in the same schools. It means real learning opportunities for groups who have traditionally been excluded. These include children with disabilities as well as speakers of minority languages. Inclusive systems value what every student uniquely brings to the classroom and help different groups learn and grow together.

Text 2

Inclusive education supports all students in a community or class regardless of their strengths or weaknesses and helps them reach their full potential. It includes strategies, methods, and activities that promote equal education for everyone. However, there are several challenges when it comes to including students with disabilities.

The first problem is that teachers are not trained enough. Teachers are vital in inclusive learning, but many people do not know how to teach or support children with disabilities. In some cultures, this makes things even worse, leading to discrimination and blocking access to education.

Next is the lack of inclusive teaching methods. These methods needs financial support, but funding is often not available. Without any financial support, it is difficult to provide training for teachers and school specialists. However, this is a crucial for inclusive education.

Another challenge is the lack of accessible technology. Inclusive education needs an environment that works for everyone. Without this technology, it is hard to make education respectful, fair, and free from discrimination.

The last challenge is curriculum. A strict curriculum that does not offer different teaching methods for students with disabilities prevents successful inclusion. Moreover, if study plans do not consider different ways of learning, students with disabilities will not benefit much from the school experience.

Scientists are trying to fabricate diamonds at lower temperatures. The ability of diamonds to deal with high electrical voltages and effectively disperse heat makes them valuable in the semiconductor sector. However, enormous heat is often needed to create diamonds.

Researchers are trying to find methods to grow diamonds at lower temperatures without losing quality. They discovered that acetylene gas can help diamonds growing but also can create soot, which is not useful. The key is to control the temperature. Above a certain temperature, acetylene helps diamonds growing, but below that temperature, it creates soot. Soot can be defined as a mass of impure carbon particles resulting from the incomplete combustion of hydrocarbons. Soot is considered a hazardous substance with carcinogenic properties.

Hydrogen also plays a role in diamond growth. Hydrogen dissociation is crucial for transforming methane into acetylene and transporting atomic hydrogen to the diamond growth surface. More hydrogen near the surface means more diamond can form, even at lower temperatures.

The researchers are also studying a special type of diamond called quantum diamond, which has nitrogen-vacancy (NV) centers. These NV centers are useful for quantum computing and sensing. The challenges is to add a single layer of hydrogen atoms to the diamond surface without damaging the NV centers.

Text 2

Carbon is a common element found in many things around us. It can form different materials, like diamond and soot, depending on how its atoms are arranged. Diamond is a form of carbon where atoms are arranged in a crystal lattice. This structure makes diamond very hard and able to withstand high temperatures and pressures. Diamonds are used in jewellery because they sparkle, but they are also important in industry. They can cut through hard materials and are used in electronics because they can conduct heat very well.

Soot is another form of carbon, but it is very different from diamond. Soot is made of tiny black particles that are produced when something burns incompletely, like wood or coal. It is often seen as black smoke from chimneys or car exhausts. Soot can be harmful to health if inhaled and can also cause pollution.

The diferrence between diamond and soot comes from how the carbon atoms are arranged. In diamonds, the atoms are tightly packed in a strong, regular pattern. In soot, the atoms are loosely arranged in a random pattern, making it soft and powdery.

Scientists are interested in how to control the formation of diamond and soot. By understanding the conditions that lead to each form, they can create diamonds in laboratories for various uses. For example, diamonds can grown at lower temperature to be used in electronics without damaging other components.

Soal 35

Mudah

According to Text 1, hydrogen dissociation is important in the diamond growth process because it ....

(A)
can be accelerated using methane to form NV centers without damaging the diamond's surface.
(B)
can react with acetylene to produce soot that can grow diamonds at low temperatures.
