Multi‐Material Gradient Printing Using Meniscus‐enabled Projection Stereolithography (MAPS)

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
MAPS is a new vat‐free printing technique that utilizes programmed delivery of resin droplets with custom formulations to enable multi‐material gradient printing of 3D structures with user‐defined variations in mechanical stiffness, opacity, surface energy, cell densities, and magnetic properties. Abstract Light‐based additive manufacturing methods are

Post-quantum public key-agreement scheme based on a new form of the hidden logarithm problem [PDF]

open access: yesComputer Science Journal of Moldova, 2019
A new form of the hidden discrete logarithm problem, proposed as primitive of the post-quantum public-key cryptoschemes, is defined over the 6-dimensional finite non-commutative associative algebra with a large set of the left-sided global units.

The discrete logarithmic Minkowski problem

open access: yes, 2014
Existence of solution of the logarithmic Minkowski problem is proved for the case where the discrete measures on the unit sphere satisfy the subspace concentration condition with respect to some special proper subspaces. In order to understand how optimal this condition is, we discuss certain conditions that any cone volume measure satisfies.

Driving Micro‐Objects Using Optical Force due to Fluorescence Emission From Molecules

open access: yesAdvanced Optical Materials, EarlyView.
Emission of fluorescence from a micro‐object in a specific direction is expected to generate an optical force driving the object in the opposite direction of the emission, like a rocket. To demonstrate this ‘photon‐driven micro‐rocket’, we prepared dye‐doped polymer micro‐object (PMO) one surface of which was covered with metallic film; the PMO ...

Efficient Low‐Voltage Phase Shifter with Inkjet‐Printed Liquid Crystal on a Silicon on Insulator Platform

open access: yesAdvanced Optical Materials, EarlyView.
Demonstration of an electro‐optic phase shifter fabricated by inkjet printing liquid crystal on an integrated silicon photonics chip surface. On a completed silicon photonics wafer (including modulators, detectors, and metallization), the back‐end‐of‐line stack is opened up to inkjet‐print liquid crystal. A phase shift of 6 for 2.7 V is obtained within

A Secure Anonymous E-Voting System based on Discrete Logarithm Problem

open access: yes, 2014
In this paper, we propose a practical and secure anonymous Internet voting protocol. This method integrates Internet reality and cryptology. Issues such as the kinds of "certificate authority" and " public proxy server" are integrated in our scheme to ...

Breaking Crystallinity for Optimal Dark Current: Nonfullerene Acceptor Dilution as a Strategy for High‐Performance Organic Photodetectors

open access: yesAdvanced Optical Materials, Volume 13, Issue 19, July 4, 2025.
Organic photodetectors (OPDs) based on polymer donor:non‐fullerene‐acceptor (NFA) bulk heterojunction blends offer strong light‐sensing potential, but require methods for optimization. This work demonstrates NFA dilution as an effective strategy to suppress dark current and enable state‐of‐the‐art performance by disrupting NFA crystallinity.
