Three years ago, back in December 2020, we were excited to launch the 20th issue of the journal Materials for Sports History [Spanish: Materiales para la Historia del Deporte (MHD)]. Since then, the issues from 21st to25th have been published. Among others, two monographics are included: one related to physical education, coordinated by Jean Saint ...

Mechanical and Electrical Properties of Free‐standing Polycrystal Diamond Membranes
We demonstrate a novel approach for synthesizing free‐standing and transferable polycrystalline diamond membranes (PCDm). Two types of PCDm cantilevers—Top‐Surface‐Up (TSU) and Bottom‐Surface‐Up (BSU)—are fabricated and systematically analyzed for mechanical and electrical properties, including elastic modulus, Bandgap, sheet resistance under the ...

Housing Affordability and Upward Mobility from Public to Private Housing in Singapore [PDF]
This paper examines the ability of buyers to afford and upgrade to private housing using the experience in land scarce Singapore as a case study. The concepts of the “threshold buyer” and “threshold upgrader” are introduced to construct an operational ...

The dimensions of the giant globes built in the second half of the nineteenth century quickly make us forget that they are paradigmatic cases of miniaturized worlds. This article focuses on Élisée Reclus’s project for the Paris “Exposition Universelle” of 1900. A relief globe of about 127 meters in diameter was to be housed in an even bigger globe. The

Mobility‐Lifetime Products in Organic Infrared Photodiodes with Peak Absorption at 1550 nm
This study analyzes the mobility‐lifetime products in organic infrared photodiodes with different donor‐to‐acceptor ratios to examine charge collection performance. Abstract Infrared photodiodes based on organic semiconductors are promising for low‐cost sensors that operate at room temperature. However, their realization remains hampered by poor device

Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives
The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.

Low Cost and High Speed Look-Up Table Implementation of Xilinx FPGA
There are two methods to implement LUT up to 7-bit depends on the type of Xilinx chip hardware and the software that can use in design and the code generation. The first method implements LUT as a RAM.
