Living solar panel wallpaper harvests energy thanks to photosynthesis

Researchers created an incredible  energy-harvesting wallpaper by inkjet-printing circuitry and cyanobacteria on paper. The cyanobacteria lived through the printing process, and then performed photosynthesis to harvest power. Imperial College London described the product as a two-in-one solar bio-battery and solar panel , and said an iPad-sized piece of the wallpaper could energize a digital clock or LED light bulb. Imperial College London, University of Cambridge , and Central Saint Martins researchers worked together on the project. They utilized cyanobacteria as ink, printing the bacteria with an inkjet printer onto electrically conductive carbon nanotubes , which had also been inkjet-printed on the paper, according to Imperial College London . The cyanobacteria – still alive – performed photosynthesis, allowing the bio-solar panel to harvest electrical energy.

Marin Sawa of Imperial College London said in a statement, “Imagine a paper-based, disposable environmental sensor disguised as wallpaper, which could monitor air quality in the home. When it has done its job it could be removed and left to biodegrade in the garden without any impact on the environment.” The research offers a development in microbial biophotovoltaics (BPV) technology , exploiting “the ability of cyanobacteria and other algae that use photosynthesis to convert light energy into an electrical current using water as the source of electrons,” according to Imperial College London. Cyanobacteria can not only generate electricity during the day, but at night as well, from molecules they produced in daylight. BPVs can be difficult to scale up – two obstacles being expense and lifespan – but the team’s use of an off-the-shelf inkjet printer could allow them to scale up the technology easily. Andrea Fantuzzi, also of Imperial College London, said paper-based BPVs wouldn’t be used to produce solar power on a large scale, “but instead could be used to construct power supplies that are both disposable and biodegradable. Their low power output means they are more suited to devices and applications that require a small and finite amount of energy, such as environmental sensing and biosensors .” The journal Nature Communications published the research online yesterday.

Delhi residents struggle to breathe as doctors declare air pollution health emergency

Filed under Eco, Green

Doctors in Delhi, India’s capital region, have declared a public health emergency over the densely populated, metropolitan area’s extremely high level of air pollution , the breathing of which has been described as the equivalent of smoking 50 cigarettes in a day. The Indian Medical Association has called for the capital city’s upcoming half-marathon to be cancelled to avoid “disastrous health consequences” and urges residents to remain inside to protect themselves from the pollution. Arvind Kejriwal, chief minister of Delhi, described the city as “a gas chamber,” according to the Guardian , while he and other officials work to determine an effective response to the crisis. As the region struggles to breath, state and federal government have been urged to take action to protect its citizens. In response to the public health emergency, schools have been closed while transportation routes have suffered delays under the decreased visibility. While the smog contains a number of noxious chemicals, the most destructive are concentrations of fine pollutants smaller than 2.5 micro-meters, which are so tiny that they are able to slip through natural filters in the human body. These fine pollutants, which include lead, arsenic, cadmium and mercury, have reached concentrations in the air eleven times the level defined as safe by the World Health Organization. “It has terrible effects on every part of your body,” said Dr. Arvind Kumar, chest surgery chairman at Sir Ganga Ram hospital in Delhi, according to the Guardian . “It can precipitate an acute asthma attack and in the long run it will increase their risk of lung cancer .” Related: India to only sell electric cars by 2030 Delhi’s air is polluted for much of the year due to open burning of trash, road dust, exhaust from vehicles, and byproducts of industrial activity. However, it becomes even more unbearable in winter when seasonal changes trap the pollution closer to the ground. Attempts to improve Delhi’s air quality have included traffic rationing, shuttering of local coal power plants , and even banning fireworks during Diwali. Unfortunately, to truly tackle this urgent problem, local, state, and federal governments will need to examine the complex systems that result in an outpouring of pollution and craft comprehensive policies to discourage unhealthy practices and encourage healthy ones.

This modular orphanage in Thailand was built using local and recycled materials

November 7, 2017 by  
Filed under Green, Recycle

This cluster of tiny shelters for Burmese children in Thailand was built using reclaimed wood and locally sourced materials . Following the success of his Casa Techo emergency dwellings in Colombia, Chilean architect Sebastián Contreras Rodriguez developed a modular design that can be adapted to local conditions and material availability. The Hua-Fai – Youth Center is located in the city of Mae Sot in northwest Thailand close to the Burmese border. As this part of the country is prone to floods, the architect designed raised modules that stand 2.62 feet (80 cm) off the ground with steel profiles anchored to concrete dice. Related: Iranian Architect Builds Sustainable Bamboo Dome From Bamboo and Dry Rice Plants Rodriguez collaborated with Estudio Cavernas and a.gor.a architects to build the structures. Each unit can house two kids with a bedroom on the upper floor, and a social area on the lower level. Recycled wood taken from demolished houses was used to create the main trusses, while eucalyptus logs facilitate natural ventilation. The roofing is made from sugarcane leaves sourced from an adjacent site. + Sebastián Contreras Rodriguez + Estudio Cavernas + a.gor.a architects Photos by Juan Cuevas, Alejandro Sánchez, Albert Company-Olmo

Comments Off on The iKnife Helps Surgeons Find Tumors by Sniffing Out Cancer

Removing cancerous tumors from a patient is a very precise science, and it can be very difficult for surgeons to determine where tumors begin and end. That’s why chemist Zoltan Takats and his team of researchers from the medical school at Imperial College London designed the iKnife , a brilliant scalpel that can help physicians determine whether the tissues they’re removing are cancerous. The knife could save precious time in the operating room , and it could ultimately make surgeries much faster, safer and more effective.
