this is peter finlay with the red cross. we are trying to set up an operation to supply health, medical attention, water, sanitation, hygiene, shelter, all of this amongst the covid epidemic, which makes incoming aid workers extra time to get in. remember, in november2010, you got off the plane and you were in the middle of the disaster. now you have to go through a series of health barriers to just get into the country. and when you are in the country, you make a line to get on an aircraft to get to the area. now, there is a security situation in some parts of the main road to le cai, and that s another consideration, so it s just a very complicated humanitarian crisis that has been exasperated by the storm. at least 25 rural health centres have been destroyed. doctors have been working in makeshift tents.
that s likely to put increased upward pressure on inflation, notjust in rising prices but lengthening queues and waiting times. andy verity, bbc news. a tropical storm that hit haiti overnight is hampering rescue work in the aftermath of the earthquake on the weekend. more than 1,400 people have been killed. thousands more are injured. our correspondent james clayton reports from the town of le cai, which is in the path off the storm. the church behind me is called l eglise du sacre coeur, and as you can see, it s been hugely impacted by this earthquake. you can see right the way through it. there is a statue of the virgin mary completely smashed, there are these huge lines that cut across the church that is structurally unsound, and actually the locals have told me they are worried about that spire up there could fall at any moment because there are these huge cracks down the side of it. up across the road, you have the local coffin maker, a small business trying
jab, and over 77% have had both doses. the medicines regulator says it is safe and actually receive the job. a tropical storm that hit haiti overnight is hampering rescue work in the aftermath of the earthquake which struck the island at the weekend. more than 1,400 people have been killed, and thousands more are injured. 0ur correspondent james clayton reports from the town of le cai, which is in the path of the storm. the church behind me is called l eglise du sacre coeur. and, as you can see, it s been hugely impacted by this earthquake. you can see right the way through it. there is a statue of the virgin mary completely smashed, there are these

The rapid development of silicon-based transistors leads to its integration getting closer to the limit of Moore s law. Graphene is expected to become the next generation of mainstream chip materials due to its ultra-high carrier mobility. However, it is difficult to obtain a high on/off current ratio for intrinsic graphene-based transistor owing to the absence of bandgap. Graphene nanoribbons, which possess a tunable bandgap and unique optoelectrical properties, have attracted extensive attention and exploration.
Nowadays, the preparation of graphene nanoribbons is underdeveloped, and common strategies include the clip of carbon materials (graphene films, carbon nanotubes, or graphite) and direct-growth on a specific substrate surface. All these methods are inspiring but also exhibit narrow scope they require concession steps to prepare precursors or pre-functionalize substrate as templates. The hundreds of nanometers in length, alignment problem and c
