Molekul Terbaru Mengubah Karbon dioksida Menjadi Bahan Bakar

6/14/2017 Add Comment





Molekul CO2 berinteraksi dengan Renium (Biru) dan mengubahnya menjadi Karbon monoksida.

(Ben Noffke And Richard Schaugaard)


Kita tidak bisa hanya mengurangi emisi karbon saja untuk menghadang pemanasan global, hal inilah yang membuat peneliti mencari cara untuk mendaur ulang karbon dioksida menjadi sumber bahan bakar berbahan karbon netral. Baru-baru ini tim peneliti yang dipimpin oleh Profesor Liang-shi dari Universitas Indiana tengah mencari cara untuk mewujudkannya dengan menggunakan sinar matahari dan suatu molekul kimia khusus.
Molekul tersebut adalah sepotong nanografene dengan atom renium yang terikat. Nanographene bertindak sebagai pengumpul surya dengan menyerap energi sinar matahari dan mentransmisikan energinya menuju renium, sehingga memecah molekul karbon dioksida menjadi karbon monoksida yang dapat digunakan sebagai bahan bakar. Terobosan yang terdapat dalam Journal of American Chemical Society. "Karbon monoksida merupakan bahan baku penting dalam berbagai proses industri," ungkap Profesor Li. "Ini juga merupakan cara untuk menyimpan energi sebagai bahan bakar netral karbon karena Anda tidak menyumbang karbon kembali ke atmosfir lebih dari yang telah Anda gunakan. Anda hanya melepaskan kembali tenaga surya yang Anda gunakan untuk membuatnya."

Tim melihat ke dalam renium, yang digunakan dalam molekul bipiridin, karena pengaruhnya dalam mengurangi karbon dioksida sudah diteliti. Namun bipyridine ini membutuhkan sinar UV. Oleh karena itulah mereka menggunakan graphene (hanya memiliki satu lapisan atom karbon) untuk menyerap sinar matahari sebanyak mungkin dan mentransfer energi tersebut.
Li juga menambahkan jika kita bias membuat molekul yang cukup efisien untuk reaksi ini, akan diproduksi energy bebas dan dapat disimpan dalam bentuk bahan bakar, dan penelitian ini merupakan lompatan besar kea arah itu.
Daun nanographene berperan sebagai sel surya. Cahaya menghasilkan arus melaluinya, dengan elektron yang mengalir menuju “mesin" renium, yang memecah molekul CO2 dan melepaskan karbon monoksida.
Terobosan ini hanyalah langkah awal, meski tim sudah sibuk menjajaki langkah selanjutnya. Mereka ingin agar molekul lebih tahan sehingga tahan lama dan tidak perlu dalam bentuk cair. Mereka juga berharap bisa menemukan pengganti renium, yang merupakan logam langka. Mereka pikir mangan, yang lebih murah, mungkin saja mampu digunakan.

Materi Termodinamika I

6/14/2017 Add Comment


JRENG-JRENG..... TERMODINAMIKA :o

Post pertama dibagian materi sengaja Om pilih Termodinamika wkakakk
Kenapa?? Karena mata kuliah inilah khususnya di Teknik Mesin yang banyak GA LULUS nya.
adek bertanya : Om lulus ga?
Om : Lulus dongg.. meskipun berakhir di nilai yaa begitulah.. "yang penting lulus" :v

Jadi buat para bontengers apalagi yang jurusan teknik mesin harap pelajari baik-baik nih. inilah neraka teknik mesin nomer 1. huahahahaha

Sedikit tentang termodinamika, Termodinamika adalah ilmu yang mempelajari energi, panas, kerja, entropi dan lain-lain (maap ga paham seluruhnya). Ya intinya nanti kalian bakalan belajar kayak perpindahan panas, proses di lemari es. Nah yang paling LIEUR (pusing) itu baca tabel termodinamikanya. Banyak sekali yang harus dicari belum lagi kalo harus diiterasi biar dapat nilainya. Kalo kalian jago Termonya enak nih kerja di pembangkit listrik.

Biasanya univ saya kalo ujian itu cuman 4 soal buat 2 jam dan sepengalaman saya ga pernah beres semua ke isi :"). Selain itu nilai-nilai juga rata-ratanya kecil. yang nilai 80 keatas bisa diitung pake jari. udahlah curhatnya cukup segitu :v

 Silahkan dinikmati Bontengers

Unilever Young Entrepreneurs Awards 2017

Unilever Young Entrepreneurs Awards 2017

6/14/2017 Add Comment

If you’ve got an initiative, product or service already in action that’s tackling a sustainability problem, or you know someone else whose brilliant work deserves recognition, we want to hear from you. 

Details

About the Unilever Young Entrepreneurs Awards
Celebrating young sustainability innovators - The Unilever Young Entrepreneurs Awards are all about supporting and celebrating inspirational young people from all over the world with existing initiatives, products or services that are tackling some of the planet’s biggest sustainability challenges.
We are living in a world where temperatures are rising, water shortages are more frequent, food supplies are increasingly scarce and the gap between rich and poor is increasing. Populations are growing fast, making basic hygiene and sanitation even more of a challenge.
We can overcome these challenges and build a bright future for everyone, if we work together. But to do this, the world needs a plan. These Awards recognise 18 to 35 year olds who are putting ideas into action.
Why are we doing all this? We see a big opportunity: to support, inspire, reward and collaborate with a new generation of the world’s most brilliant young changemakers; innovators who are the future of sustainability. Imagine what we can achieve together.
We are looking for innovative and scalable technologies or initiatives that are contributing to one or more of these four categories:
Farm to Table
In this category, we are looking for inspiring entrepreneurs who are working on sustainable initiatives relating to food and drink production right through to consumption.
We are looking for entrepreneurs who can demonstrate innovation that not only protects the planet’s natural resources, but will help to transform our food systems, offering a long-term approach that can create value and enhanced livelihoods for farmers, and ensure security of supply for the long-term. Entries should ensure issues such as deforestation and land use, alongside social and community issues are managed responsibly. You may be working with smallholder farmers to improve their environmental practices across their supply chain, or helping them with social programmes such as access to education, community empowerment initiatives or encouraging young people into agriculture.
However, it’s not all about sustainable agriculture - we also want to hear from entrepreneurs who are working in the area of food and drink consumption and nutrition. You may be working to inspire and inform people about sustainable nutrition or helping them to make better choices. Perhaps you are creating food and drink products that support the long-term health of people and the planet.
Opportunities for Women
We are seeking initiatives that help to tackle the discrimination and disadvantages millions of women face around the world. You might be working to help provide access to skills and training for women, and creating opportunities for women to actively, safely and fairly participate in the economy.
Alternatively, you might be working on a micro-enterprise initiative to help women on low-incomes escape poverty.
From Australia to Zimbabwe, if you are creating opportunities for women somewhere in the world, we want to hear from you!
Waste
Are there entrepreneurs out there with ingenious initiatives that help to tackle waste – to reduce, reuse or recycle waste throughout the pre-production, production and consumption lifecycle? Initiatives should demonstrate a clear business (financial), consumer (benefit), social and environmental case.
We are looking for initiatives across the waste spectrum – not just initiatives tackling packaging waste. For example, you could be developing an ingenious solution to reduce or rethink the choice of materials in production phase, or running a project that helps improve the livelihoods of people who are working in waste collection, or working on a recycling incentive scheme that is set to revolutionise the way a country tackles their waste issue, or an idea to reuse waste materials.
If it’s about tackling waste of any sort, we want to hear from you!
Water
Are you working on an initiative that tackles water scarcity, or one that addresses water pollution or sanitation and hygiene issues?
We are looking for solutions that conserve or reduce the amount of water used across communities, or during the extraction or cultivation of raw materials or through manufacturing processes. Perhaps you have an initiative that is helping people and organisations better manage access to water and adopt tools and behaviours which help them use less in the home or in a business?
Individuals in the developing world can be healthier—and communities more productive—if they have access to clean water and better sanitation. We are also seeking entrepreneurs with initiatives that address how to improve hygiene practices in any country, or offer an innovation to improve access to sanitation in remote areas.
