In this paper we investigated In2S3 as substitute for CdS, which is conventionally used as buffer layer in chalcopyrite based solar cells. In2S3 thin films were deposited by CBD and co-evaporation met...
Pancreatic β-cells are interconnected by gap junctions, which allow small molecules to pass from cell to cell. In spite of the importance of the gap junctions in cellular communication, modeling studi...
Zooming in on cells(图)     cells  microscopy technique  proteins  bacteria       font style='font-size:12px;'> 2010/3/24
For two decades, scientists have been pursuing a potential new way to treat bacterial infections, using naturally occurring proteins known as antimicrobial peptides (AMPs) that kill bacteria by poking...
Immune cells use 'bungee of death' to kill dangerous cells     Immune cells  bungee of death  dangerous cells       font style='font-size:12px;'> 2010/3/10
Immune cells use a bungee-like nanotube to snare dangerous cells, according to new research funded by the Medical Research Council (MRC).The findings by researchers from Imperial College London show t...
A new technique to study protein dynamics in living cells has been created by a team of University of Illinois scientists, and evidence yielded from the new method indicates that an in vivo environmen...
The most important hail event recorded in the region of the Ebro Valley (NE Spain) in 2004 was the 11 September episode. Large hailstones (some of them with a diameter of over 30 mm) caused important ...
Rain cells are structures which represent an important component of convective precipitation and a study of their properties represents a necessary step both towards improved stochastic models of smal...
Two strategies to identify tumor cells were developed in this research via analyzing the activity of telomerase inside the cells, which is regarded as the mark enzyme of tumors. The lysate of cells wa...
Skin cells ruffle to heal open wounds(图)     Skin cells  open wounds       font style='font-size:12px;'> 2009/12/8
Skin cells migrating to heal a wound have been observed in fine detail thanks to a novel form of microscopy developed by physicists in Taiwan. The method involves tracking tiny waves rippling along th...
We study experimentally the propagation dynamics and interaction of a pair of mutually incoherent nematicons: spatial optical solitons in nematic liquid crystals. In contrast to earlier studies, we co...
X-ray diffraction microscopy peers into tiny cells(图)     X-ray diffraction microscopy  tiny cells       font style='font-size:12px;'> 2009/11/24
Two independent groups of physicists have found a new way to get high-definition glimpses of the innards of living cells. The technique uses X-ray diffraction microscopy on cells frozen below –170 °C,...
Why blood cells move in slippers(图)     blood cells  move in slippers  blood vessels       font style='font-size:12px;'> 2009/11/24
Physicists in France and the US claim to have discovered why red blood cells adopt asymmetrical "slipper" shapes in small blood vessels. If correct, the knowledge could be used to diagnose certain dis...
Keeping track of time is one of the brain's most important tasks. As the brain processes the flood of sights and sounds it encounters, it must also remember when each event occurred. But how does that...
A new carbon nanotube sensor developed at MIT is the first sensor that can reversibly detect nitric oxide, a gas that cells commonly use to communicate with each other. Because the nitric oxide-carbon...
Displacement damage dose is applied to analyze the irradiation effects of 2 MeV carbon ions and 0.28~20 MeV protons on homemade GaAs/Ge solar cells. The NIEL for each ion is modified by taking into a...
