Deformation and strengthening behavior of Al-Cu-based alloys at ambient and elevated temperatures

Academia Materials Science
Aluminum alloys typically exhibit low to intermediate strength. Heat treatment may improve their strength through precipitation hardening. Al-Cu-based alloys have shown appropriate mechanical properties based on their specific strengthening ...

How far behind in number are socioeconomically disadvantaged pupils when they start school in England?

British Educational Research Journal, EarlyView.
Abstract This paper examines the gap in number skills between socioeconomically disadvantaged and non‐disadvantaged children in the first year of compulsory schooling in England. Past research mostly relies on statutory assessment data collected towards the end of the first year of school and does not show the attainment gap associated with ...

Engineering of 2‐ketoacid Decarboxylases for Production of Isobutanol and Other Fusel Alcohols in Saccharomyces cerevisiae

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Isobutanol is a fusel alcohol that can be produced microbially for use as a biofuel or upgraded into sustainable aviation fuel (SAF). A key enzyme in the isobutanol biosynthetic pathway is 2‐ketoacid decarboxylase (KDC), which irreversibly decarboxylates 2‐ketoisovalerate (KIV) to yield isobutyraldehyde.

Global Energy Corporations and Climate Change: The Role of Formal and Informal Institutions in Shaping Climate Change Risk Disclosure

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines climate change risk disclosure in the global energy sector, where firms face intense stakeholder scrutiny and legitimacy pressures. We develop a novel domain‐specific textual analysis measure to capture climate change risk disclosures, improving on prior approaches based on generic environmental terminology.

Fluorescence Properties and Mg2+ Selectivity of Aryl‐Alkynyl Derivatives of the o‐Aminophenoltriacetate (APTRA) Ligand

Chemistry – A European Journal, EarlyView.
It is a challenge to improve the selectivity of high‐denticity ligands for Mg2+ over Ca2+. We show that in aryl‐alkynyl derivatives of APTRA, electron‐withdrawing substituents lower the binding affinity for Ca2+ more than Mg2+, making the ligand more selective for Mg2+.

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Exploring Sustainability Reporting Practices in an Emerging Market: Insights From Corporate Governance and Disclosure Tone

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The study examines how narrative disclosure tones (NDTs) and corporate governance mechanisms (CGMs) affect sustainability reporting practices (SRP) in an emerging economy. Data from 125 non‐financial firms in Pakistan, spanning 2011–2022, are utilized. SRP is measured using both GRI and the novel IFRS S1 standards‐based indices. Three NDTs are
