Compounds useful for associating with nanoparticle or microparticle emulsions to obtain magnetic resonance images permit control of the relaxivity of the signal and readily associate with the particulate components. The compounds are conveniently prepared from achiral derivatives of chelating moieties.

We describe pH-sensitive endosomolytic polymers, delivery particles containing pH-sensitive endosomolytic polymers. The described particles are capable of delivering polynucleotides to cells from the peripheral circulation with subsequent release from endosomes. The endosomolytic polymers are inactive outside the cell but disrupt membranes upon exposure to an acidified endosomal compartment.

An ink jet printer which is a recording device which ejects ink droplets onto a recording surface of a recording medium thereby recording, includes a material of slave rollers that are in contact with the recording surface in a transport path through which the recording medium is transported, the material being located on a polarity side opposite to a polarity in which mist that is generated in accordance with ejection of the ink droplets in a charge string is charged, further than a material of a member which configures the recording surface.

An image forming apparatus includes a transfer unit transferring a toner image on a first face of a sheet, a fixing unit fixing the toner image onto the first face of the sheet, and a sheet detecting unit detecting the sheet in a sheet transporting path. The sheet detecting unit includes a rotator which rotates by a slide contact on a second face which is backside of the first face of the sheet, and a supporting member which supports the rotator rotatably. The rotator is comprised of a material which is charged by the slide contact on the sheet with a first polarity, the first polarity being opposed to a second polarity with which a toner of the toner image is charged. The supporting member is comprised of a material charged by the slide contact on the sheet with the second polarity.

It is possible to provide a device and a method for combusting particulate substances which particulate matters discharged from an internal combustion engine can be effectively combusted, and the device configuration is simple and does not become large and heavy. The combustion device has: an introduction portion 8 used to introduce a particulate matter-containing gas 5 discharged from the exhaust port of an internal combustion engine; a charging unit 11 which is provided on the downstream side of the introduction portion 8, and in which all or part of the particulate matters 6′ are e negatively charged by bringing the particulate matter-containing gas into contact with; an electric discharge unit 15 which is provided in an insulation pipe 100 which is connected to the downstream side of the charging unit 11, and in which the particulate matters 6′, all or part of which are negatively charged, are introduced into a silent discharge area A1 and are combusted with an increased retention time, the silent discharge area being generated between an anode and a cathode; a discharge portion 9 which is connected to the insulation pipe 100 at the downstream side of the electric discharge unit and which discharges the combusted gas; and a power source unit which applies an electric field to the charging unit and the electric discharge unit.

Apparatus is provided, including a plurality of islets, and a hydrogel configured to macroencapsulate the plurality of islets. The hydrogel is implantable in a subcapsular space (21) of a kidney (22) of a subject and is shaped to define a planar configuration. Other applications are also described.

Described herein are systems and methods for the generation of electric current and / or electric potential utilizing micro- or nano-channels and capillary flow, including fluidic or microfluidic batteries and electrochemical cells. The provided systems and methods use capillary force to promote fluid flow through micro- and nano-fluidic channels by evaporating fluid at one terminus of the channel, and the resulting fluid flow generates electric potential and or current. Advantageously, the described systems and methods remove the need for pressurized vessels or external pumps, increasing net energy generation and decreasing complexity and size of potential fluidic batteries.
