Hard and soft EM in bayesian network learning from incomplete data

Ruggieri, Andrea ; Stranieri, Francesco ; Stella, Fabio ; Scutari, Marco

In: Algorithms, 2020, vol. 13, no. 12, p. 17

Incomplete data are a common feature in many domains, from clinical trials to industrial applications. Bayesian networks (BNs) are often used in these domains because of their graphical and causal interpretations. BN parameter learning from incomplete data is usually implemented with the Expectation-Maximisation algorithm (EM), which computes the relevant sufficient statistics (“soft EM”) ...

Covalent triazine frameworks incorporating charged polypyrrole channels for high-performance lithium–sulfur batteries

Kim, Jiheon ; Elabd, Ahmed ; Chung, Sung-Yoon ; Coskun, Ali ; Choi, Jang Wook

In: Chemistry of Materials, 2020, vol. 32, no. 10, p. 4185–4193

Organosulfur polymers have emerged as promising electrode materials for lithium– sulfur (Li–S) batteries, mainly because of their ability to incorporate and stabilize high sulfur content. The low ionic and electronic conductivity of these polymers, however, limit their cycling performance at high active mass loadings. Moreover, Li–polysulfide (Li–PS) shuttling, a fatal phenomenon in...

Variations of the Herschel–Bulkley exponent reflecting contributions of the viscous continuous phase to the shear rate-dependent stress of soft glassy materials

Caggioni, Marco ; Trappe, Veronique ; Spicer, Patrick T.

In: Journal of Rheology, 2020, vol. 64, no. 2, p. 413–422

We explore the flow behavior of concentrated emulsions for which the viscosity of the continuous phase can be significantly varied by changing the temperature. The exponents obtained by fitting the shear rate-dependent stress with the popular Herschel–Bulkley (HB) model display a systematic dependence on the viscosity of the continuous phase, revealing that viscous dissipation via the...

Colloidal gelation, a means to study elasto-capillarity effects in foam

Mikhailovskaya, Alesya ; Trappe, Véronique ; Salonen, Anniina

In: Soft Matter, 2020, vol. 16, no. 9, p. 2249–2255

We explore the evolution of the mechanical properties of a coarsening foam containing colloidal particles that undergo a sol–gel transition in the continuous phase. This enables us to investigate the impact of elasto-capillarity on foam mechanics over a wide range of elasto-capillary numbers. Right after initiating aggregation the foam mechanics is predominantly determined by the elasticity...

Hierarchically porous reduced graphene oxide coated with metal–organic framework hkust-1 for enhanced hydrogen gas affinity

Song, Kyung Seob ; Kim, Daeok ; Coskun, Ali

In: ACS Applied Nano Materials, 2020, vol. 3, no. 2, p. 985–991

Metal–organic frameworks (MOFs) are crystalline porous materials that have been actively explored for various gas storage, separation, and conversion applications because of their structural tunability. While the micropores (<2 nm) in MOFs are essential for increased gas affinity, these small pores significantly decrease the mass-transport kinetics. One way to address this challenge is to ...

A pyrene–poly(acrylic acid)–polyrotaxane supramolecular binder network for high-performance silicon negative electrodes

Cho, Yunshik ; Kim, Jaemin ; Elabd, Ahmed ; Choi, Sunghun ; Park, Kiho ; Kwon, Tae‐woo ; Lee, Jungmin ; Char, Kookheon ; Coskun, Ali ; Choi, Jang Wook

Although being incorporated in commercial lithium‐ion batteries for a while, the weight portion of silicon monoxide (SiOx, x ≈ 1) is only less than 10 wt% due to the insufficient cycle life. Along this line, polymeric binders that can assist in maintaining the mechanical integrity and interfacial stability of SiOx electrodes are desired to realize higher contents of SiOx. Herein, a...

Colloidal dynamics and elasticity of dense wax particle suspensions over a wide range of volume fractions when tuning the softness by temperature

Yoon, Jiwon ; Scheffold, Frank ; Ahn, Kyung Hyun

In: Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2019, vol. 576, p. 1–8

We report on the colloidal dynamics and rheology of liquid droplet emulsions and solid particle suspensions over a wide range of volume fractions. Diffusing wave spectroscopy and rheometry were utilized to study the micro/macroscale properties of 1-eicosene wax particles dispersed in water. By changing the temperature, the wax droplets change their properties from soft to hard or vice versa,...

Highly elastic polyrotaxane binders for mechanically stable lithium hosts in lithium‐metal batteries

Yoo, Dong‐Joo ; Elabd, Ahmed ; Choi, Sunghun ; Cho, Yunshik ; Kim, Jaemin ; Lee, Seung Jong ; Choi, Seung Ho ; Kwon, Tae‐woo ; Char, Kookheon ; Kim, Ki Jae ; Coskun, Ali ; Choi, Jang Wook

In: Advanced Materials, 2019, vol. 31, no. 29, p. 1901645

Despite their unparalleled theoretical capacity, lithium‐metal anodes suffer from well‐ known indiscriminate dendrite growth and parasitic surface reactions. Conductive scaffolds with lithium uptake capacity are recently highlighted as promising lithium hosts, and carbon nanotubes (CNTs) are an ideal candidate for this purpose because of their capability of percolating a conductive...
