Room‐Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots

open access: yesAdvanced Functional Materials, EarlyView.
CsPbX3${\rm CsPbX}_3$ lead halide perovskite quantum dots (QDs) are synthesized in a room‐temperature, five‐minute synthesis, yielding size‐controlled QDs with bright, tunable emission governed by reaction conditions and halide composition. A strongly binding ligand, OD‐PEA, ensures months‐long stability under ambient conditions and facilitates their ...

Influence of Wear-Induced Turning on the Roll’s Fatigue Life

open access: yesMetals
Friction-induced wear during the rolling process needs periodic remachining of caliber roll grooves, which increases operational costs and reduces roll fatigue life.

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

To roll or not to roll(?) is the yield stress (in soft particulate gels)

open access: yes
While it is widely acknowledged that system-spanning particulate structures contribute to the observed yield stress and shear-thinning in attractive colloidal gels, a comprehensive understanding of the underlying microscopic mechanisms remains elusive.

Stress calculation of Plate Rolling

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1949
圧延機の円〓ロールの圧延部における円弧を, 頂点の曲率半径がロール半径に等しき双曲線にて置き換え, ロール圧力σ, 圧延方向の応力σnおよびロ一ル而の摩擦力τを考慮に入れて力の平衡式を立て, これに最大せん断応力説による塑性変形條件を入れてパラメータ表現法によつて解を得た.ロール面と圧延素材間の相対速度の方向によつてτの方向は変り, ために生ずる2種の式に, 入口と出口とにおいてσn=0,相対速度=0の所にて両式のσnが等しき條件より未定数を定めた.終りに数値例題を附記して計算の経路を示した.

Single‐Step Recovery of Water from Stable Crude Oil‐Water Emulsion Using Surface Engineered Hybrid Inorganic‐Polymer Membranes

open access: yesAdvanced Functional Materials, EarlyView.
Atomic layer deposition is used to conformally surface engineer polymeric membranes to fabricate inorganic–organic hybrid membranes. These membranes have exceptionally strong attraction toward water even in high oil containing emulsions, which leads to an extremely strong hydration layer at the interface.

Stress distributions along the roll contact arc [PDF]

open access: yesE3S Web of Conferences
The article provides the results of a mathematical description of the distribution of contact stresses of a roll module with smooth rollers. Analysis of the developed models shows that when the rollers rotate, the maximum of the normal stress ...

From Photoalignment to Structured Light: Liquid Crystal Platforms for Beam Shaping and Complex Wavefronts

open access: yesAdvanced Functional Materials, EarlyView.
Photoaligned and photopatterned liquid crystal platforms provide programmable control of optical phase, polarization, and spin‐orbit interactions, enabling compact generation of structured light and complex wavefronts. This review highlights how tailored molecular orientations transform simple beams into designed optical fields, opening versatile ...

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

open access: yesAdvanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable
