Evidence: 100 • authority: 72

Exotic materials are minerals and metals that have uncommon characteristics, such as high strength, hardness, density, durability or radioactivity. It does not mean any material that is rare per se, but rather one that is exceptional in its physical or mechanical characteristics. Exotic materials are used for high performance tasks such as aerospace engineering, armour, cutting tools and nuclear technology, where ordinary materials may fail under stress, heat, wear, corrosion or impact.

The following is a list of experimental cat breeds and crossbreeds that do not have the recognition of any major national or international cat registries, such as The International Cat Association (TICA) in the US, Europe, and Australasia; the Governing Council of the Cat Fancy (GCCF) in the UK, the Fédération Internationale Féline (FiFE) in continental Europe, the Cat Fanciers' Association (CFA) in North America, or the more recent World Cat Federation based in Germany. Such a breed may be recognized by one of the smaller cat registries. Smaller registries include the Rare and Exotic Feline Registry (REFR), and others. This list only includes breeds recognized by at least one extant, natio…

Assembling a True "Olympic Gel" From over 16 000 Combinatorial DNA Rings.. Olympic gels are an elusive form of soft matter, comprising a 3D network of mechanically interlocked cyclic molecules. In the absence of defined network junctions, the high conformational freedom of the molecules was previously theorized to confer unique mechanical properties to Olympic gels, such as non-linear elasticity and unconventional swelling characteristics. However, the synthesis of an Olympic gel exhibiting these intriguing features is challenging, since unintended crosslinking and polymerization processes are often favored over cyclization. Here, we report the successful assembly of a true Olympic gel from…

The Stabilization of High-Nitrogen Systems: 10 Catenated Nitrogen Chain.. High-nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high-nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass percentage increase. Although approaches such as introducing alternating positive/negative charges and restricting electrocyclic N 2 loss have been reported for stabilizing high-nitrogen systems, these structural motifs have not previously been applied to highly catenated nitrogen chains. Accordingly, we sought to design a new highly catenate…

Mechanical, Physical, and Morphological Characteristics of Concrete Incorporating Wastewater Treatment Plant Sludge as a Supplementary Cementitious Material. The production of wastewater treatment plant (WWTP) sludge is constantly increasing due to global population growth, posing significant environmental challenges related to its sustainable management. This study aims to present an innovative approach for reusing dried waste sludge (DSS) as a cementitious additive in concrete production, contributing to reducing waste generated by WWTPs and mitigating negative environmental impacts. DSS was incorporated into concrete mixtures by replacing cement at levels of 0%, 5%, 10%, and 15% by weigh…

Repurposing Si CMOS nonidealities for stochastic and analog image processing.. Conventional semiconductor device engineering regards intrinsic device nonidealities as reliability concerns to be minimized or eliminated. Here, we demonstrate the strategic repurposing of these nonidealities as functional resources for advanced stochastic analog computing. We leverage two underutilized phenomena-deep-level channel trap-induced generation-recombination (G-R) noise and impact ionization-induced negative differential resistance (NDR) in body current-which have received limited attention compared to the extensively studied 1/ f noise and monotonic drain current behavior in logic-centric transistors…

Optimising (Al,Ga) (As,Bi) Quantum Well Laser Structures for Reflectance Mode Pulse Oximetry.. We explore quantum well laser diodes for applications in pulse oximetry based on two material systems, namely, classical AlGaAs and a rather exotic GaAsBi, with lasing at around 800 nm and 1100 nm, respectively. These spectral regions and material families were selected due to their closely matched effective penetration depths into soft tissue. An improved design of the band structure of device active areas was tested on both material systems, yielding enhancement of the two main parameters, namely, output power and threshold current. A maximum emission power of the AlGaAs laser diode was register…

An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting.…

In philosophy and metaphysics, materialism is a form of monism holding that matter is the fundamental substance of nature, so that all things, including mind and consciousness, arise from material interactions and depend on physical processes, including those of the human brain and nervous system. It contrasts with monistic idealism, which treats consciousness as fundamental, and is related to naturalism, the view that only natural laws and forces operate in the universe, and to physicalism, the view that all that exists is ultimately physical. Physicalism extends materialism by including forms of physicality beyond ordinary matter (e.g. spacetime, energy, forces, exotic matter), and some u…

An exotic pet is a pet which is relatively rare or unusual to keep, or is generally thought of as a wild species rather than as a domesticated pet. The definition varies by culture and location, and over time, as a given species becomes firmly enough established in the world of animal fancy, it may no longer be considered exotic.

Child pornography (CP), also known as child sexual abuse material (CSAM), is erotic material that involves or depicts persons under the local age of majority or age of consent. The precise characteristics of what constitutes child pornography vary by criminal jurisdiction. Child pornography is often produced through online solicitation, coercion, and covert photography. Sexual abuse (such as statutory rape or forcible rape) is mainly involved during its production. Pornographic pictures of minors are also often produced by children and teenagers without the involvement of an adult. CSAM images and videos are frequently collected and shared online. Laws regarding child pornography generally…
