BNT - A Korean research team develops the world's

first eco-friendly filter that removes microplastics from water

A collaboration between the two technologies: ‘electrophoresis’ of Kiwon and ‘triboelectric generator’ of DGIST


The Korea Institute of Industrial Technology (KITECH) and the Daegu Gyeongbuk Institute of Science and Technology (DIGIST) joint research team announced on the 6th that they have developed the first eco-friendly filter that can remove not only micro but also nano-sized microplastics from water. As the world's first eco-friendly filter that removes microplastics without environmental pollution, it is expected to contribute to solving the problem of microplastics, which is emerging as a major environmental problem. The result was published in the June 11 online edition of ‘Nano Energy’, an international academic journal in the field of energy engineering, and is scheduled to be published in September.

Microplastics in Drinking Water and Oceans

Microplastics are small plastic particles less than 5 mm in diameter. There are primary microplastics, which are made small from the beginning, and secondary microplastics, which are finely broken and split. It mainly flows into the sea and contaminates the marine ecosystem. Through the disruption of the endocrine system of marine organisms, it accumulates in humans, the top predator, and acts as a threatening factor, such as disturbing human body functions.

The severity of the microplastic problem and its dangers to humans have been constantly warned for a long time. (Link to article – ‘Concentration of microplastics in your blood’) However, microplastics are so small that it is difficult to separate or process them with filters that have been used to filter out impurities. In particular, in the case of ultra-fine plastics having a nanometer (nm) size smaller than a micrometer (㎛), the filter may be clogged or the filter itself may cause pollution of the marine ecosystem.

In the midst of the need for a new method of environmentally friendly microplastic removal technology that can overcome these limitations, an eco-friendly power plant that removes microparticles in water was developed for the first time. A joint research team led by Dr. Cho Han-cheol's research team from the Precision Machinery Process Control Research Group at the Korea Institute of Industrial Technology and Professor Joo-hyeok Lee of the Department of Energy Engineering at DGIST succeeded in developing an eco-friendly particle removal technology that can treat microplastic particles in water for the first time in the world.

What is the principle of the eco-friendly microplastic filter? Electrophoresis and TENG
As a fine particle removal technique, ‘electrophoresis’ technology was used. It is a technique to separate organic substances using electrical properties. When a strong electric field is generated in water, micro and nano particles in the water quickly move toward the electrode (substrate) and adhere to it, thereby removing microplastic particles. The research team paid attention to the fact that the efficiency of electrophoresis can be increased through high voltage. In addition, it developed a new microparticle removal technology that removes microplastics by grafting a triboelectric generator capable of outputting high voltage and low current.

BNT - Biden makes surprise first visit to Ukraine


US President Joe Biden, who was scheduled to visit Poland this week, made his first visit to Kyiv since the start of the war.

US President Joe Biden made an unannounced visit to Ukraine Monday, February 20, to meet with President Volodymyr Zelensky, a gesture of solidarity that comes days before the one-year anniversary of Russia's invasion of the country.

"One year later, Kyiv stands," Biden said. "And Ukraine stands. Democracy stands. The Americans stand with you, and the world stands with you." Biden spent more than five hours in the Ukrainian capital, consulting with Zelensky on next steps, honoring the country’s fallen soldiers and meeting with US embassy staff in the war-torn country. 

Biden delivered remarks with Zelensky at Mariinsky Palace to announce an additional half billion dollars in US assistance and to reassure Ukraine of American and allied support as the conflict continues. "One year later, Kyiv stands. And Ukraine stands. Democracy stands," Biden said. "Joseph Biden, welcome to Kyiv! Your visit is an extremely important sign of support for all Ukrainians," Zelensky wrote on Telegram, in English.

Biden stressed his "unflagging commitment" in defending Ukraine's territorial integrity, and promised new arms. He announced an additional half-billion dollars in US assistance, including shells for howitzers, anti-tank missiles, air surveillance radars and other aid but no new advanced weaponry.

BNT - Biden to 'contrast notes' and Sunak on Ukrainian fightback



Joe Biden is supposed to raise worries over the harmony cycle in Northern Ireland and examine the Ukrainian counter-hostile against Russia with Rishi Sunak when they meet one week from now.

The US President will meet the Top state leader in London and with the Ruler at Windsor Palace on Monday prior to making a beeline for the Nato highest point in Lithuania.

There has been criticism of Mr. Biden's plan to provide Ukraine with cluster munitions, which are prohibited by many allies, including Britain, and he will arrive in the UK.

The White House said that Mr. Biden and Mr. Sunak would "compare notes" during their fifth meeting in as many months regarding their support for Ukraine and the situation on the battlefield.

However, post-Brexit tensions are also likely to be discussed by Mr. Biden, who has previously stated that he wants to ensure that the "Brits didn't screw around" in Northern Ireland.

Amanda Sloat, Europe senior director for the National Security Council, told reporters: He continues to place a strong emphasis on cooperating with the United Kingdom and Ireland as well as maintaining peace, prosperity, and stability throughout the entire region.

"I would imagine that those would be the general range of topics that they would discuss," and "Northern Ireland is certainly an issue that the President regularly talks about with his British counterpart" are just a few examples.

During his time in the UK, Mr. Biden will also attend a climate finance mobilization forum that focuses on supporting developing nations.

On Tuesday, both men will meet with their Nato allies in Vilnius to discuss Ukraine's bid for membership.

Ms Sloat said: " Given that both leaders will be flying to Vilnius the day before, I imagine this will be a chance for them to update each other on developments in discussions leading up to the Vilnius summit.

"It will be a chance for them to share any useful info on both of our help for Ukraine and their continuous endeavors on the front line."

The UK is one of 123 signatories to the Show on Bunch Weapons, which forbids their utilization or accumulating due to their aimless impact on regular citizen populaces.

The weapons scatter a lot of bomblets over a large area.

Even after conflicts are over, bombs that haven't been detonated may still be a threat to civilians.

House Safeguard Advisory group director Tobias Ellwood asked the US to "rethink".

BNT - Sister Roma


Republicans Walk Out As Drag Nun ‘Sister Roma’ Honored At California Capitol

Protest took a back seat to the celebration at the California Capitol Monday as lawmakers honored drag nun Sister Roma and proclaimed June LGBTQ+ Pride Month. Roma, who belongs to the San Francisco-based Sisters of Perpetual Indulgence, was one of 15 guests invited by the legislature’s LGBTQ+ Caucus as the Assembly and Senate passed resolutions proclaiming June as LGBTQ+ pride month. Republicans in the Senate called on Senate President pro Tem Toni Atkins of San Diego to revoke Roma’s invitation last Thursday. A group of Catholic and evangelical Christian demonstrators gathered on the Capitol’s west steps Monday afternoon to protest Roma’s recognition. In the Assembly, when Roma came to the front to receive her award, Republican members left the floor and retreated to the lounge in the rear of the chamber. The remaining members clapped, whooped, and cheered, giving Roma a prolonged standing ovation. Fellow honoree Harry Lit shouted from the back of the chamber, "Love you Roma!" Speaking to the Senate, Democratic Senator Susan Talamantes Eggman of Stockton introduced the pride resolution and noted that she identified as a proud Catholic.

Currently in Ukraine: The most recent

 

BNT - Developments include:

Following a slowdown in ship inspections, U.N. Secretary-General Antonio Guterres urges parties to the Black Sea Grain Initiative to "accelerate operations."
According to the British defense ministry, Russia has made "significant effort" in recent weeks to construct defensive lines, particularly on the roads leading to the occupied Crimea by Russia.
Three drones were shot down by Russia's air defenses in the Moscow region, according to the defense ministry on Wednesday.

Russia claimed that the drones were a part of an attack by Ukraine and that two of them were stopped as they got close to military warehouses.

Ukraine rarely discusses Russian attacks.

Over the Khmelnytskyi region in western Ukraine, the Ukrainian military claimed to have shot down six Shahed drones made by Iran.

Since its invasion of Ukraine in February 2022, Russia has utilized frequent drone attacks as part of its aerial assault on targets there.

Tuesday's Russian attack, Ukraine claimed, resulted in the downing of 32 of 35 drones.

NATO expansion Sweden is expressing optimism that it will be able to join the alliance in the three weeks leading up to the summit of NATO leaders in Vilnius, Lithuania.

On Wednesday, Swedish Foreign Minister Tobias Billstrom told Reuters that Turkey's parliament should begin ratifying Sweden's application to join NATO.

In response to Russia's invasion of Ukraine, Sweden and Finland applied for membership. Sweden's accession has been stalled due to Turkey's objections to what it claimed was Sweden's lack of action against groups Turkey considers terrorists. Finland joined officially in April.

As part of an agreement to address security concerns that was reached with Turkey last year, Sweden has implemented a number of reforms, one of which is a new anti-terror law.

On the sidelines of a meeting in parliament, Billstrom told Reuters, "Our judgment is that we have done what was expected of us, now it is time for the Turkish parliament to start the ratification process."

"¡Ronaldo no podría jugar aquí!"


El entrenador principal niega el rumor de transferencia de CR7 Sin embargo, la carrera de Ronaldo puede haber tomado un giro completamente diferente el verano pasado, cuando los rumores de su insatisfacción con Man Utd comenzaron a surgir unas semanas antes de que la frustración del jugador finalmente llegara a su punto de ruptura con una entrevista explosiva que terminó su etapa en la Premier League.

A pesar de que el campo del jugador inicialmente se mostró cauteloso sobre la posibilidad de que pudiera dejar Old Trafford, poco después hubo rumores de que estaba vinculado a casi todos los clubes importantes en las cinco ligas principales de Europa, e incluso algunos fuera de estos campeonatos líderes, y que incluso podría dejar Old Trafford.

Una de las rutas más plausibles con un fichaje por el Atlético de Madrid, un equipo que en ese momento necesitaba desesperadamente un delantero centro y que residía en una ciudad que Ronaldo ya conocía y en la que ya se había establecido.

Cristiano Ronaldo en el Al-Nassr: goles, asistencias, resultados y próximos partidos de Simeone: Diego Simeone, el entrenador de la selección española, rompió ahora el silencio sobre estos rumores y afirmó que "CR7" no habría cruzado la línea divisoria entre el Real Madrid y el Atlético de Madrid. No intenté fichar a Ronaldo.

Le preguntaron sobre la posibilidad de traer de vuelta a LaLiga al gran delantero hace un año cuando hablaba con la COPE.

Afirmó: "No lo intenté". Aunque es un jugador excepcional, Cristiano Ronaldo no pudo jugar en el Atlético de Madrid, al igual que Diego Simeone no pudo entrenar al Real Madrid.

El argentino cree que el problema está en la excesiva rivalidad de clubes sin que se mencione un posible choque de estilos.

El verano pasado se pensó que el Atlético hizo un esfuerzo por fichar a Ronaldo, pero las exigencias salariales del exdelantero del Manchester United impidieron la operación.

"Biden sends message...


...to grieving families on Memorial Day"

"Never forget the price our soldiers paid to protect American democracy," President Joe Biden said Monday morning in his Memorial Day speech.

The comments were made after Biden attended a wreath laying ceremony at the Tomb of the Unknown Soldier in Arlington, Virginia.

"We must never forget the life these flags, flowers and marble marks represent," Biden said. "Mothers, fathers, sons, daughters, sisters, spouses, friends and Americans. Every year we remind ourselves of it, but every year it doesn't get easier."

Biden's late son Bo was a major in the Army National Guard in Iraq in 2008. Tuesday, the day after Memorial Day, marks eight years since Beau Biden died of cancer.

Mr. Biden admitted in his speech that his son did not die on the battlefield, but said First Lady and First Lady Jill Biden was proud of Mr. Beau Biden's accomplishments.

"Father, I can still hear you saying that's my duty," he said. "Duty. That's the norm my son lived by, and everything you lost lived by it."

Biden said he still feels the pain of losing him "every day." The fires are particularly intense on Memorial Day, he added.

First Lady Jill Biden, Vice President Kamala Harris and Harris' husband Douglas Emhoff also attended the traditional 155th National Day wreath laying ceremony. Before the wreath of flowers and red, white, and blue ribbons, he thought for a moment, then bowed his head and prayed.

According to a news release from Arlington National Cemetery, a 155th National Day wreath and mourning program was held Monday to honor America's fallen soldiers.

"To all those here and across the country who are mourning the loss of loved ones who wore uniforms, to our Gold Star families, and to all those whose loved ones are still missing and missing. "I know how hard it is," Biden said. "It could tear a black hole in the middle of your chest." "The pain is still real, it's still raw."
