Abstract: This invention relates to a disposable pipette tip or tube designed to perform biological or chemical sample preparation, purification or separation where the samples are in a closed bottle with a lid with septum or membrane. In an automatic sampler for HPLC or Gas chromatography, septum closed vials are used to prevent samples from drying out or evaporating during the analytical process. The auto sampler needles are used to prick the septum at the vial to get the sample out for injecting in injector for the analysis. The same needle takes the samples from each vial, and therefore a contamination of the samples is possible.

Abstract: The present invention provides a process for the preparation of sol-gel modified alternative Nafion-Silica composite membrane useful for polymer electrolyte fuel cell. The said composite membrane is made by embedding silica particles in perfluorosulfonic acid ionomer by a process that circumvents the use of added acid while using acidic characteristics of Nafion and polymerization reaction through a sol-gel route. The composite membrane has high affinity for water with capability to exchange protons. The approach may be used to manufacture polymer electrolyte membrane fuel cells operating at elevated temperatures under near-zero humidity.

Abstract: The present invention provides a process for the production of high-capacity kish graphitic lithium-insertion anode materials and negative electrodes prepared therefrom for lithium-ion batteries. The graphitic materials are produced by precipitating excess carbon present in supersaturated solutions of carbon in iron/steel uninoculated or inoculated with metals/metalloid singly or in combination. The form of carbon used for dissolution is a carbon-containing polymeric precursor such as biomaterials and non-biodegradable plastic wastes, the carbonization of which can be carried out in situ or prior to addition in the melt. The graphitic products deliver reversible capacities between 300 and 600 mAh·g?1 with flat voltage profiles for electrochemical insertion/deinsertion of lithium at potentials less than 200 mV.

Abstract: A precursor chemical compound is applied to a surface sought to be coated, and subjected to a rapid thermally activated chemical reaction process (RTACRP) in which the temperature is quickly raised and lowered. The desired coating is formed from the precursor chemical compound by a chemical reaction at the elevated temperature. The structural/chemical integrity of the surface is preserved due to the use of RTACRP. The approach may be used to manufacture a high-energy density lead-acid battery.

Abstract: In this invention we describe a shaking device that is used to shake, stir, mix, rotate or agitate samples in containers attached to the shaking device. The shaking device, herein referred to as the shaker, is used to mix the solid, liquid or gaseous components of the sample in the container. The shaker described in this invention has a flexible arm to which the containers containing samples are attached. Due to the flexibility of the arm, its shape can be changed such that the speed and type of sample shaking can be varied based on the shape of the arm and based on where on the arm a sample container is attached. In this manner, orbital, linear, circular and other two or three-dimensional shaking, mixing, agitation and stirring of the sample can be achieved. The present invention provides an easy new method for shaking samples in containers of different shapes and volumes, at different speeds and in different orientations in space.

Abstract: In this invention we describe a magnet or magnetic material that is attached to a pipette to hang it on a ferrous or magnetic material. The magnet can be attached to any place on the pipette in such a way that the pipette can be hung as desired on the magnetic or ferrous surface such as ferrous clips, iron or steel sheets (refrigerator, lab bench, hood etc.). This will help to organize the laboratories. Furthermore this will reduce the contamination from pipette to pipette and sample to sample.
