Indian media and ecological issues

open access: yesEnvironment Conservation Journal
The ecological crisis of India, manifesting in the forms of rampant deforestation, pollution, water scarcity, loss of biodiversity, and several other issues, is rarely acknowledged by the mainstream Indian media.

Thickness‐Dependent Infrared Emissivity of Ultrathin Freestanding MoSiN Nanocomposite Membranes

open access: yesAdvanced Optical Materials, EarlyView.
ABSTRACT Metals and dielectrics show opposite trends in thickness‐dependent infrared emissivity: metallic films exhibit a rise in emissivity below a critical thickness, while dielectric films show a corresponding decline. For applications demanding both high emissivity and mechanical strength in membranes with nanoscale thickness, combining these ...

On mass communication and mass incommunication in Nigeria

open access: yes, 1990
Despite the prevalence of mass media institutions and 'paraphernalia' in Nigeria, the Nigerian masses still remain marginalized and denied their right to communicate through the conventional mass media.

Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption

open access: yesAdvanced Optical Materials, EarlyView.
ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Mitigating Efficiency Roll‐Off in Phosphor‐Sensitized Fluorescence OLEDs via Molecular Polarity‐Based Benzofuropyridine Host Engineering

open access: yesAdvanced Optical Materials, EarlyView.
Positional isomerism in dibenzofuran‐based n‐type hosts modulates molecular polarity, charge‐transport balance, and emissive‐layer packing. The higher‐polarity BFPDB‐2 host facilitates efficient energy funneling, reduced aggregation, and preferential dipole orientation, leading to phosphor‐sensitized fluorescence OLEDs with enhanced external quantum ...

Identity, responsibility, then politics : the Uyghur diaspora, Facebook and the construction of identity online

open access: yes, 2014
How are online and social media being used in transnational spaces? This paper presents empirical findings of an ongoing examination of the use of Facebook among the Uyghur diaspora. Described as a young ‘diaspora under construction’ (Dilnur, 2012, p.3),

Naphthyridine‐Based Donor–Acceptor Boron Difluoride Complexes Targeting Red Emission in Organic Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, EarlyView.
Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while

Soft Robotic Excretory Care Simulator for Nursing Education: Functional and Perceptual Biomimetics Approach

open access: yesAdvanced Robotics Research, EarlyView.
A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in

The merger of mass and interpersonal communication via new media : integrating metaconstructs

open access: yes, 2017
The convergence of mass and interpersonal communication requires integration of underlying processes, or theoretical metaconstructs, that originated in formerly separate research domains.
