vivo to Launch Two New Devices in South Africa

vivo Mobile has announced that it will be extending its offering in South Africa with the introduction of two new handsets. The Y12 and Y30, both evolutions in the Y-series will enter ahead of 5G towards the end of 2020.

vivo CEO, Jeff Cao says that the company plans to sit rank the top tier segment of cell phone brands in the country within the next three years. “vivo plans to provide South African consumers with a user experience beyond expectations through technology and innovative, trendsetting products,” adds Cao.

Here’s a closer look at vivo’s new devices:

vivo Y12

The vivo Y12 is available in Aqua Blue or Burgundy Red and requires just one hand to work as it’s specifically designed for gesture controls. It sports an AI Super-Wide-Angle Camera on the back while the front is fitted with an 8MP selfie camera.

Like the other devices in the Y-series, the Y12 features an industry-leading 5,000mAh battery, supported by intelligent power-saving technologies to further extend battery life. The octa-core processor with a 12nm design and clock speeds of up to 2.0GHz means that users can install all the apps they need and can choose between two variants to ensure the smartphone runs smoothly: 3GB + 64GB or 4GB + 32GB.

vivo Y30

The Y30 is ready in Dazzle Blue or Moonlight White colours and is a stylish and sophisticated device. Sensors on the phone include accelerometer, ambient light sensor, proximity sensor, and fingerprint sensor. Plus, the vivo Y30 supports face unlock.

Like the other devices in the Y-series this device also boasts a 5000mAh non-removable battery and a 10W fast charging option to keep up with a fast-paced lifestyle.

8GB of RAM and an octa-core MediaTek Helio P35 (MT6765) processor allows for excellent storage and a device that will run smoothly – it runs Funtouch OS based on Android 10 and packs 128GB of inbuilt storage.

The rear features a 13-megapixel primary camera with an f/2.2 aperture; a second 8-megapixel camera with an f/2.2 aperture; a third 2-megapixel camera with an f/2.4 aperture and a fourth 2 MP camera with an f/2.4 aperture. It also comes with Digital Zoom, Auto Flash, Face detection and Touch to focus. The front camera also sports an 8 MP camera.

Mining Sector Set to Lead Economic Recovery in Zambia

Despite a challenging business environment in many sectors across the globe, Zambia’s wealth of natural resources continues to open the door for new investors and opportunities. As the world begins its recovery and gradual reopening in the face of the pandemic, traditional industries require energy, innovation and reinvention.

ZCCM Investments Holdings Plc. – the mining conglomerate whose major shareholder is the Government of the Republic of Zambia – is signalling its intention to take on a leadership role in Zambia’s recovery with its announcement this week that they are partnering with a new strategic mining play – Array Metals.

This company has an estimated inferred resource by JORC standards of 3 million tonnes of gold ore in Mumbwa, with 2.53.5grams per tonne totalling to about 7,500 kgs of gold – 400 million USD in today’s prices.

The two-year exploration study in Zambia’s Central Province entailed gold drilling of 59 holes at a depth of 150 metres, with plans to extend exploration activities to include 100 holes at a depth of 400 metres in the next five years.

The decision by ZCCM-IH to partner with Array Metals through Consolidated Gold Company (CGCZ) is a promising sign that investment in Zambia continues to move forward in the face of turbulent economic times.

This development is the result of several key long-term economic strategies coming to fruition.

First, though Zambia is famed for copper mining, a diversified economy creates resilience, inspires greater investor confidence and supports sustainable long-term growth. Though Array Metals has other new mining projects with 200 million tonnes of copper ore of 2% in Chick, Marie, Ruby, Muriri and Katwaro, in the same region, the additional focus on gold shows how Zambia’s government is working to diversify the country’s economic activities and create sustainable jobs through underexplored markets such as gold.

Furthermore, the gold mine is located under the traditional leadership Chiefdom of Chief Shakumbila in Mumbwa, Central Province. Though the mine had previously been closed for many years, the discovery of the resource through exploration has revived it. Array Metals estimates that the project will create 300 local jobs immediately, with more jobs added as mining begins in earnest.

Another key feature of the endeavour: ZCCM-IH’s partnership with Array Metals encourages mid-sized mining firms venturing into exploration and mining activities. Array Metals has urged the government to support a new generation of smaller companies to take advantage of the opportunities afforded by new discoveries.

In the past, it has been unclear whether medium-sized companies have the capacity to perform mining exploration and mining activities. This partnership is an example that shows that Zambia’s mining sector is ripe for new players and that the barrier to entry is not as high as investors once assumed.

In comparison with the giants that have dominated Zambia’s mining sector, medium-sized companies are nimbler and more innovative. Array Metals is no different, with a strong focus on flexibility and deployment of the most cutting-edge technologies to streamline exploration and production. The fresh competition will spur all companies in the sector to increase outputs and efficiency, driving greater investment and progress.

As a result, larger, more established companies will no longer command monopolies, and Zambia’s government will have more leverage to garner revenue and help all citizens reap the benefits of the assets under Zambian soil.

This development also shows that there is a conducive environment for investment in Zambia more broadly. Growing production of copper and gold in Zambia, creating jobs for Zambians, increasing the country’s GDP and introducing fresh competition in key sectors will add value in both the short and the long term.

The joint venture partnership between CGCZ with Array Metals is a powerful symbol to international investors, increasing confidence in Zambia’s mining sector and in the Zambian economy overall. In times of uncertainty, investors must weigh their decisions carefully. This partnership is a step forward that demonstrates to Zambians and to the world that ZCCM-IH is looking toward the future.

New Device Uses Shadows to Generate Electricity

In an interesting twist in emerging technologies and the energy sector, a team of researchers from the National University of Singapore (NUS) has created a device called the Shadow-Effect Energy Generator. The device is able to create an electrical charge using the contrast between shadow and light.

It sounds like something out of a science-fiction novel, Yahoo News reports that the team behind the device capitalised on the illumination contrast caused by shadows as an indirect source of power.

“The contrast in illumination induces a voltage difference between the shadowed and illuminated sections, resulting in an electric current. This novel concept of harvesting energy in the presence of shadows is unprecedented,” says research team leader, Assistant Professor Tan Swee Ching, from the NUS Department of Materials Science and Engineering.

Based on laboratory experiments, the harvested energy from the device in the presence of shadows created under indoor lighting conditions is sufficient to charge a smartwatch at 1.2 volts.

The NUS team’s research breakthrough was reported in the scientific journal Energy & Environmental Science on 15 April.

Commercially available solar cells can harness ambient light in an outdoor environment to generate power supply. But their energy harvesting efficiency drops significantly indoors where shadows are prevalent.

The device can perform two functions – to convert illumination contrast from partial shadows castings into electricity, and to serve as a proximity sensor to monitor passing objects. It comprises a set of cells on a flexible and transparent plastic film, with each cell comprising a thin film of gold deposited on a silicon wafer.

“We also found that the optimum surface area for electricity generation is when half of the SEG cell is illuminated and the other half in shadow, as this gives enough area for charge generation and collection respectively,” said co-team leader, Professor Andrew Wee, from the NUS Department of Physics.

The NUS team will next experiment with other materials, besides gold, to reduce the cost of the device. It will also explore developing self-powered sensors and wearable SEGs attached to clothing.
