The invention relates to the use of a microdevice for the modification of protein with carbohydrate. Preferably for the glycation of protein with a mono-, di-, oligo- or polysaccharide(s). The invention also relates to the process for modifying protein with carbohydrate in a microdevice. The invention also relates to a process for preparing a food, feed, personal care, cosmetic, pharmaceutical, paper or corrugated board product comprising the process steps to prepare the modified protein and the step of combining the modified protein with at least one other ingredient.

Disclosed herein are chemical actuators and ionic motive force transducers. The actuators and transducers are capable of converting an electrical stimulus into an ionic gradient within a reaction volume.

Methods are disclosed for operating devices in diffusion-limited regimes, where diffusion rates are sufficiently low that device operation can be optimized by taking the rate of diffusion into account when directing devices what actions to take.

The present invention is related to an electrochemical reactor (1) and a microfluidic platform (20) comprising this reactor (1), controlling pH in a closed environment, wherein this reactor (1) comprises at least one cell (2), wherein each cell (2) containing at least one micro-well (3a) able to contain a liquid and reagents and a cap (7) to close the said cell (2) and wherein the cell (2) further comprises at least one working electrode (5) producing reversible REDOX reactions.

A device for hydrogen production with waste aluminum includes a treatment apparatus for waste aluminum and a reaction tank. The apparatus includes a first crusher, a pickling tank, and a second crusher. The first crusher is for preliminarily crushing waste aluminum to obtain first aluminum chips. The pickling tank is for receiving and pickling the first aluminum chips crushed by the first crusher. The second crusher is for receiving and fine crushing the first aluminum chips to obtain second aluminum chips. The second aluminum chips are received by the reaction tank and then hydrolyzed with an alkaline solution in the reaction tank to produce hydrogen. Since waste aluminum is used as the raw material of hydrogen production, and a specific device is used for waste aluminum treatment, so the effects of recovering waste metal, reducing environmental damage, and saving costs can be achieved at the same time.

A method and device to adjust the concentration of at least two gasses in a fluid, wherein the method involves adjusting the concentration of a first gas in the fluid by adjusting the concentration of a second gas in the fluid wherein the first and second gases are kept separate until dissolved in the fluid.

A microfluidic device for storing a reagent includes a single unit includes a first portion having a reagent storage chamber configured to hold a reagent. The device also includes a second portion having a reaction chamber configured to support the reagent during a reaction process to form a product. The device also includes a valve configured to isolate the reagent storage compartment from the reaction chamber when the valve is in a closed state.

Embodiments described herein provide micro-fluidic systems and devices for use in performing various diagnostic and analytical tests. According to one embodiment, the micro-fluidic device includes a sample chamber for receiving a sample, and a reaction chamber for performing a chemical reaction. A bubble jet pump is structured on the device to control delivery of a fluid from the sample chamber to the reaction chamber. The pump is fluidically coupled to one or more chambers of the device using a fluidic channel such as a capillary. A valve may be coupled to one or more chambers to control flow into and out of those chambers. Also, a sensor may be positioned in one or more of the chambers, such as the reactant chamber, for sensing a property of the fluid within the chamber as well as the presence of a chemical within the chamber.
