The expanding dowel pin further includes a double-tapered cylinder with tapered cones tapering more narrowly from its middle. The expanding dowel pin further includes a lower collet with a lower-collet, inside-conical bore which has one or more lower-collet slits.

The compression by the bolt results in the expansion of the upper-collet and the lower-collet.

Abstract: Systems, methods, and techniques are described herein for characterizing well treatment fluids and well treatment fluid performance. For example, well treatment fluids can be characterized using microfluidic chips to determine fluid properties, with very small amounts of fluid used for the characterization process. Optical analysis and electrical conductivity analysis of well treatment fluids as they pass through different microfluidic pathways with different cross-sectional dimensions can be used to gain information about the well treatment fluid's composition, structure, and performance. In some cases, microfluidic pathways can be functionalized as a model for a wellbore and a reservoir (e.g., rock in the reservoir) to evaluate the performance of well treatment fluids by imaging the well treatment fluid as it flows into or through the functionalized model. These systems, methods, and techniques can allow for optimization of well treatment fluids prior to or during drilling or completion operations.

Abstract: A single solar battery device formed by a solid-state Li battery intrinsically stacked on a monolithic triple junction solar cell sharing the same electrode in between. The solar cell generates a voltage high enough to directly photo-charge a Li battery at the required C-rate without use of a converter. The subcells of the monolithic triple junction solar cell are connected monolithically in series via optimized tunnel recombination junctions through which electrons and holes from the connected subcells can recombine. The intrinsic integration of the battery with solar cell enables using of a single device without an external cable connection, thus facilitating and decreasing the installation cost.

Abstract: The invention relates to a perovskite solar cell modified by a chelating layer and its preparation method, within the field of perovskite material preparation. The process involves spin-coating N, N?-bis(4-pyridyl)-1,4,5,8-naphthalenetetracarboxylic diimide (DPNDI) solution on the perovskite surface, followed by annealing. This modification forms a chelating structure on the surface, passivating defect sites and grain boundaries, promoting charge transfer with optimized energy levels and carrier mobility. The Pb (II) coordination polymer layer enhances bonding strength and adhesion, effectively suppressing traps. The treated perovskite solar cell achieves a photoelectric conversion efficiency (PCE) of 24.2%, with a T80 lifetime retaining over 95% (40° C.) and 85% (85° C.) of the initial PCE after 2000 hours. This modified film inhibits ion migration, providing enhanced stability and high photoelectric conversion efficiency in optoelectronic devices.
