2D/2D/0D TiO2/C3N4/Ti3C2 MXene composite S-scheme photocatalyst with enhanced CO2 reduction activity

, 2020
Herein, two-dimensional (2D) TiO2 mesoporous nanosheets with three to four C3N4 layers grown in situ are employed to design a core–shell 2D/2D van der Waals heterojunction (TiO2/C3N4). Edge-terminated zero-dimensional (0D) Ti3C2 MXene quantum dots (TCQD)

Prime Numbers and Highly Composite Numbers

2012
In 1915, Ramanujan wrote a long paper on “highly composite numbers.” This paper gives us a general method to analyse the growth of arithmetic functions. It is curious that this paper finds no discussion in Hardy’s “Twelve lectures.” In hindsight, we learn that the theory has a rich structure as well as interplay with other parts of number theory ...

Anion‐Sorbent Composite Separators for High‐Rate Lithium‐Ion Batteries

Advances in Materials, 2019
Novel composite separators containing metal–organic‐framework (MOF) particles and poly(vinyl alcohol) are fabricated by the electrospinning process. The MOF particles containing opened metal sites can spontaneously adsorb anions while allowing effective ...

A review of failure modes and fracture analysis of aircraft composite materials

, 2020
Composite material-based structures have become increasingly common for aircraft construction. While a large number of researches focused on the understanding of composite materials and structures’ behavior under a variety of scenarios to determine their

Notes on composite numbers

Proceedings of the Institution of Electrical Engineers, 1963
A certain number system, governing combinatorial operations of elements of a given set, is provided. The operations are commutative, associative and distributive. The system rules countable sets of elements, i.e. parameters, such as define a complex number, and serves for precise and compact statements and for rational evaluation of explicit computable

On distinguishing prime numbers from composite numbers

21st Annual Symposium on Foundations of Computer Science (sfcs 1980), 1980
A new algorithm for testing primality is presented. The algorithm is distinguishable from the lovely algorithms of Solvay and Strassen [36], Miller [27] and Rabin [32] in that its assertions of primality are certain (i.e., provable from Peano's axioms) rather than dependent on unproven hypothesis (Miller) or probability (Solovay-Strassen, Rabin).
