In the mutant plants deficient in light-induced phosphorylation of PSII less than every second PSII has a phosphoryl group and the adjacent grana membranes are pressed to each other and enlarged [7] in the absence of the electrostatic repulsion.
Conductivity measurements were carried out on membranes with 8 mm diameter, sandwiched between gas diffusion layers, which were pressed on the membrane surfaces by two porous stainless steel discs inside a homemade sample chamber [11, 12] that controls both the temperature and the relative humidity.
The pellets were pressed on hydraulic press at 1687.2 kg/cm2.
On the Microsoft Natural Elite keyboard, the cord is woven through several small gaps in the top cover to diffuse and relieve strain from pulls on it before leading to the circuit board, which connects to the membrane with an edge connector that rests against the membrane, which in turn is pressed down by a rubber pad.
Whereafter, the PVDF membrane bearing the CNTs/AgNWs is pressed against the PET substrate at a moderate pressure of 3 MPa, because we found that in our experiments the sheet resistance of AgNW film has little change when pressed at a pressure of more than 3 MPa, so 3 MPa is enough for a AgNW film to reduce resistance.
A drop of immersion oil was placed on top of the filter membrane, and a cover slip was pressed firmly on the oil, with the oil forming a seal at the edge.
In this method, a sharp glass capillary (patch-clamp electrode) is pressed against the plasma membrane of the cell, and suction is applied to form a tight seal (gigaohm seal) between the membrane and the electrode.
And underneath the keys of computer keyboards are membranes with printed circuits that sense when a key is pressed.
The tip of the AFM (sometimes shaped as a small sphere) is pressed against the cell so that the membrane is indented.
The silicone was painted over and around the membrane-facing side of the chip leaving <4 mm area around the membrane, and a piranha-cleaned, rinsed and dried #1 glass coverslip was pressed against the chip.
